Öğe ANTHRAX IN UPPER EYELID(NOBEL ILAC, 2013) Koktekir, Bengu Ekinci; Sumer, Sua; Gedik, Sansal; Okudan, SuleymanAnthrax is an acute infection caused by Bacillus anthracis. Although it is a zoonotic disease that mainly affects herbivorous animals, it might also be contagious to humans by infected animals. The most common type is skin anthrax. When eyelid is involved; echymosis, bulla formation and necrosis can be observed. We report a 75 years old woman presenting with bilateral extensive lid echymosis and edema and diagnosed as anthrax. The clinical findings resolved with appropriate systemic and topical antibiotic treatment, and the lesions on the eyelid resulted with scatrizating ectropion. In failure of early diagnosis and treatment, there is a high risk of mortality and sequela with this particular disease which rarely involves eyelids.Öğe Association of Apolioprotein E Polymorphism with Intravitreal Ranibizumab Treatment Outcomes in Age-Related Macular Degeneration(KARGER, 2014) Bakbak, Berker; Ozturk, Banu Turgut; Zamani, Ayse Gul; Gonul, Saban; Gedik, Sansal; Yildirim, Selman; Okudan, Suleyman[Abstract not Available]Öğe Association of Apolipoprotein E Polymorphism with Intravitreal Ranibizumab Treatment Outcomes in Age-Related Macular Degeneration(TAYLOR & FRANCIS INC, 2016) Bakbak, Berker; Ozturk, Banu Turgut; Zamani, Ayse Gul; Gonul, Saban; Iyit, Neslihan; Gedik, Sansal; Yildirim, M. SelmanPurpose: Genetic factors are known to influence the response to anti-vascular endothelial growth factor (VEGF) treatment in exudative age-related macular degeneration (AMD). The current study was conducted to investigate the association of Apolipoprotein E (ApoE) polymorphism with the treatment response to ranibizumab for exudative AMD.Methods: One hundred nine eyes (109 patients, 59.6% male, mean age 63.847.22 years) treated with intravitreal ranibizumab injections were included in the analysis. Smoking status and lesion type were recorded. Patients were categorized into three groups according to visual acuity (VA) change at 6 months after the first injection: VA loss >5 Early Treatment Diabetic Retinopathy Study (ETDRS) letters (Group 1); VA change between five ETDRS letters gain and loss (Group 2); VA improvement >5 ETDRS letters (Group 3). The association of ApoE gene polymorphisms with the three groups was evaluated.Results: Both smoking status and lesion type showed no significant association with VA change (p=0.12 and p=0.64, respectively). A lower frequency of 2 and a higher frequency of 4 were observed in Group 3 (2.9 and 25.7%, respectively). VA improvement with more than five ETDRS letters was significantly associated with the presence of the 4 genotype (p=0.01).Conclusions: This study demonstrated that carriers of the ApoE 4 polymorphism genotype show demonstrable improvement in VA after treatment with ranibizumab in exudative AMD. ApoE polymorphism identification may be used as a genetic screening to tailor individualized therapeutic approach for optimal treatment in neovascular AMD.Öğe Bilateral Papillophlebitis in a Patient with Mutation of Metilenetetrahydrofolate Reductase Enzyme(TURKISH OPHTHALMOLOGICAL SOC, 2016) Guzel, Huseyin; Ozturk, Banu Turgut; Gedik, Sansal; Bakbak, Berker; Beyoglu, Abdullah; Kocak, NadirPapillophlebitis is known as central retinal vein occlusion seen in young patients. It usually presents as unilateral optic disc edema with cotton wool spots and hemorrhage in the peripapillary region. As it may be due to many autoimmune and inflammatory causes, a thorough systemic evaluation of the patient is warranted. In this case report we describe a bilateral, simultaneous papillophlebitis case thought to be related to hyperhomocysteinemia secondary to C677T polymorphism of methylenetetrahyrofolate reductase enzyme.Öğe Bilateral severe anterior uveitis after unilateral selective laser trabeculoplasty(WILEY, 2013) Koktekir, Bengu E.; Gedik, Sansal; Bakbak, Berker[Abstract not Available]Öğe Bilateral Tonic Pupils in the Absence of Pupillary Cholinergic Supersensitivity(INFORMA HEALTHCARE, 2012) Bakbak, Berker; Gedik, Sansal; Koktekir, Bengu Ekinci[Abstract not Available]Öğe Characteristics of the Anterior Segment Biometry and Corneal Endothelium in Eyes with Pseudoexfoliation Syndrome and Senile Cataract(TURKISH OPHTHALMOLOGICAL SOC, 2015) Bozkurt, Banu; Guzel, Huseyin; Kamis, Umit; Gedik, Sansal; Okudan, SuleymanObjectives: To evaluate the anterior segment biometric features and corneal endothelial changes in eyes with pseudoexfoliation (PEX) syndrome and senile cataract. Materials and Methods: The central corneal thickness, anterior chamber depth (ACD), pupil diameter, lens thickness, endothelial cell density (ECD), and percentages of polymegathism and pleomorphism of 52 subjects with PEX and cataract were compared with 51 age-and gender-matched control subjects with cataract using optical low-coherence reflectometry (OLCR, Lenstar LS 900; Haag Streit AG, Switzerland) and in-vivo confocal microscopy (Confo Scan 4, Nidek Co. Ltd, Osaka, Japan). Nineteen subjects with PEX syndrome had glaucoma and were using anti -glaucoma medications. Only one eye of the subjects was used in statistical analysis and a p value less than 0.05 was considered statistically significant. Results: None of the OLCR parameters reached statistically significant differences among the 3 groups (ANOVA p>0.05). The percentage of eyes with ACD <2.5 mm was 13.7% in the control group, 24.2% in PEX eyes without glaucoma and 21.1% in PEX eyes with glaucoma, with no statistically significant differences (p=0.45). There was a significant difference in mean ECD among the 3 groups (ANOVA p=0.02), whereas no differences could be found in respect to polymegathism and pleomorphism (p>0.05). Mean ECD was significantly lower in the PEX glaucoma group (2,199.5 +/- 176.8 cells/mm(2)) than the control group (2,363 +/- 229.3 cells/mm(2)) (p = 0.02), whereas no difference was found in mean ECD of PEX eyes without glaucoma and the control group (p=0.42). ECD was less than 2,000 cells/mm(2) in 15.8% of PEX subjects with glaucoma, 9.8% of control subjects and 6.1% of PEX eyes without glaucoma, with no statistically significant difference (p=0.52). Conclusion: As eyes with both PEX glaucoma and cataract seem to be associated with decreased endothelial cell number, specular or confocal microscopy screening should be done for the patients scheduled for intraocular surgery.Öğe Comparison of central corneal thickness measurements using optical low-coherence reflectometry, Fourier domain optical coherence tomography, and Scheimpflug camera(CONSEL BRASIL OFTALMOLOGIA, 2014) Gonul, Saban; Koktekir, Bengu Ekinci; Bakbak, Berker; Gedik, SansalPurpose: To compare the results of central corneal thickness (CCT) measurements obtained using optical low-coherence reflectometry (OLCR), Fourier domain optical coherence tomography (FD-OCT), and a Scheimpflug camera (SC), combined with Placido corneal topography. Methods: A total of 25 healthy subjects were enrolled in the present study, and one eye of each subject was included. A detailed ophthalmic examination was performed in all cases following CCT measurements with OLCR, FD-OCT, and SC. The results were compared using an ANOVA test. Bland-Altman analysis was used to demonstrate agreement between methods. Intra-examiner repeatability was assessed by using intraclass correlation coefficients (ICCs). Results: Statistically significant differences were observed between the results of the CCT measurements obtained using the three different devices (p=0.009). Significant correlations were found between OLCR and FD-OCT (r=0.97; p<0.0001), FD-OCT and SC (r=0.91; p<0.0001), and OLCR and SC (r=0.95; p<0.0001). The 95% limits of agreement (LOA) obtained from Bland-Altman plots were from -7.2 mu m to 28.7 mu m for OLCR versus FD-OCT, from -19.2 mu m to 30.4 mu m for OLCR versus SC, and from -42.6 to 32.3 mu m for FD-OCT versus SC. Intra-examiner repeatability was excellent for each method, with ICCs >0.98. Conclusions: Although the results of CCT measurements obtained from these three devices were highly correlated with one another and the mean differences between instruments were comparable with the reported diurnal CCT fluctuation, the measurements are not directly interchangeable in clinical practice because of the wide LOA values.Öğe Comparison of Central Corneal Thickness Measurements With Optical Low-Coherence Reflectometry and Ultrasound Pachymetry and Reproducibility of Both Devices(LIPPINCOTT WILLIAMS & WILKINS, 2012) Koktekir, Bengu E.; Gedik, Sansal; Bakbak, BerkerPurpose: To compare the accuracy of optical low-coherence reflectometry (Lenstar LS 900; Haag Streit, Koniz, Switzerland) and conventional ultrasound pachymetry (UP) (US 4000; Nidek, Japan) for measuring central corneal thickness and to assess the interexaminer reproducibilities of both devices. Methods: Department of Ophthalmology, Selcuklu Faculty of Medicine, Selcuk University was the study setting. Central corneal thickness (CCT) was measured in both eyes of 65 emmetropic patients by the same examiner using Lenstar LS 900 noncontact biometry and UP. To assess the interexaminer reproducibility, 2 different examiners consecutively obtained CCT measurements in 16 eyes with Lenstar LS 900 noncontact biometry and UP. Results: Mean CCT measurements with Lenstar LS 900 noncontact biometry and ultrasound biometry were 541.09 +/- 33.8 and 545.69 +/- 34.0, respectively. Significant correlation was present between these 2 measurements; intraclass correlation coefficient was found to be 95.8% (95% confidence interval: 93.2%-97.4%) (P < 0.001). Interexaminer reproducibility with Lenstar was high, and the intraclass correlation was found to be 99.3% (95% confidence interval: 98.0%-99.7%). We have also investigated the interexaminer reproducibility with UP in these 16 patients, and the results showed a 99.2% (95% confidence interval: 97.7%-99.7%) intraclass correlation. Conclusions: The results of Lenstar LS 900 noncontact biometry correlated with the results of UP. It may be used as an alternative method to UP for measuring CCT. Because of the mild underestimation of CCT by Lenstar, the measurements should be carefully evaluated in patients whose intraocular pressure must strictly be monitored.Öğe Comparison of pupil diameter measurement with Lenstar LS 900 and OPD Scan II. Not interchangeable devices(SAUDI MED J, 2012) Gedik, Sansal; Koktekir, Bengu E.; Bakbak, Berker; Gonul, Saban[Abstract not Available]Öğe Comparison of the Effect of Unilateral Intravitreal Bevacizumab and Ranibizumab Injection on Diabetic Macular Edema of the Fellow Eye(MARY ANN LIEBERT, INC, 2013) Bakbak, Berker; Ozturk, Banu Turgut; Gonul, Saban; Yilmaz, Mevlut; Gedik, SansalPurpose: To find out whether intravitreally administered bevacizumab and ranibizumab affect the contralateral, untreated, eyes of patients with bilateral diabetic macular edema (DME). Methods: A retrospective review of patients with bilateral DME, who were treated with intravitreal bevacizumab or ranibizumab, was performed. All enrolled patients received intravitreal 1.25mg bevacizumab or 0.5mg ranibizumab in the eye with more severe macular edema. As outcome measures, best-corrected visual acuity (BCVA) was assessed with the Early Treatment Diabetic Retinopathy Study chart and central foveal thickness (CFT) measurement was obtained using optical coherence tomography-3 before and at 2 and 4 weeks after injections. Results: The study included 55 eyes of 55 patients who received bevacizumab (group 1) and 32 eyes of 32 patients who received ranibizumab (group 2). The mean age of the 55 patients [35 female (63.6%), 20 male (36.4%)] in group 1 was 54.3112.67 years, and the mean age of the 32 patients [20 female (62.5%), 12 male (37.5%)] in group 2 was 56.01 +/- 13.29 years. The median BCVA in the uninjected eye showed no statistically significant change at any visit after either bevacizumab or ranibizumab injection (P=0.302, P=0.582, respectively). In group 1, the median CFT in the uninjected eye was 417m at baseline; this was reduced to 401m at 2 weeks and 372m at 4 weeks. The change in CFT was found to be statistically significant (P=0.009). No statistically significant change was found in the median CFT of uninjected eyes of patients treated with ranibizumab (399, 403, and 407m before and at 2 and 4 weeks after treatment, respectively). Conclusions: Compared with ranibizumab, intravitreal administration of bevacizumab resulted in a greater decrease in macular thickness in the untreated eye, in patients with bilateral DME.Öğe Comparison of the ganglion cell complex and retinal nerve fibre layer measurements using Fourier domain optical coherence tomography to detect ganglion cell loss in non-arteritic anterior ischaemic optic neuropathy(BMJ PUBLISHING GROUP, 2013) Gonul, Saban; Koktekir, Bengu Ekinci; Bakbak, Berker; Gedik, SansalObjective To evaluate the diagnostic ability of macular ganglion cell complex (GCC) and peripapillary nerve fibre layer (NFL) measurements to detect ganglion cell loss (GCL) in patients with non-arteritic anterior ischaemic optic neuropathy (NAION), at the chronic stage. Methods This study included 10 eyes from 10 patients with NAION and 15 eyes from 15 age-matched healthy subjects. The measurements included the GCC thicknesses as average, superior and inferior, the GCC parameters as focal loss volume (FLV) and global loss volume (GLV), the NFL thicknesses as average, superior hemisphere and inferior hemisphere, and the disc parameters as rim area and rim volume. The curves for the area under the receiver operator characteristic (AUROC) were generated to assess the ability of each parameter to detect GCL. Results The patient group had significantly lower GCC thicknesses than the control group (p<0.001, <0.001 and 0.004, for the GCC average, superior and inferior, respectively), and also significantly higher FLV and GLV measurements (p<0.001). The NFL thicknesses were found to be significantly lower in the patient group than the control subjects (p<0.001). Among all the parameters, the FLV and the GLV had the highest levels of AUROC values (1.000, 0.990, respectively). Conclusions The FLV and the GLV showed the strongest abilities to detect GCL in patients with NAION. In addition, peripapillary NFL thickness was comparable to macular GCC thickness in detecting GCL. Therefore, macular GCC scans may provide a good alternative or a complementary practice to NFL scans in the detection of GCL in patients with NAION.Öğe The effect and safety of intravitreal injection of ranibizumab and bevacizumab on the corneal endothelium in the treatment of diabetic macular edema(TAYLOR & FRANCIS LTD, 2017) Guzel, Huseyin; Bakbak, Berker; Koylu, Mehmet Talay; Gonul, Saban; Ozturk, Banu; Gedik, SansalObjective: To investigate the effect and safety of intravitreal injection (IVI) of bevacizumab and ranibizumab on corneal endothelial cell count and morphology in patients with diabetic macular edema.Materials and methods: A total of 60 eyes from 60 consecutive patients who received 0.5mg/0.05ml IVIs of bevacizumab (n=30, IVB group) or 1.25mg/0.05ml ranibizumab (n=30, IVR group) for three consecutive months were investigated prospectively. Specular microscopy was performed to evaluate endothelial cell count, the percentage of hexagonal cells (pleomorphism), and the coefficient of variation of the cell size (polymegathism); optical biometry was performed to evaluate central corneal thickness. Results before injection and 1 month after the first and third injections were compared.Results: The groups were matched for age (p=0.11) and gender (p=0.32). There was no significant difference in endothelial cell count (IVB group, p=0.66; IVR group, p=0.74), pleomorphism (IVB group, p=0.44; IVR group, p=0.88) and polymegathism (IVB group, p=0.21; IVR group, p=0.24) before injection or 1 month after the first and third injections. There was also no difference in central corneal thickness (IVB group, p=0.15; IVR group, p=0.58) before injection or 1 month after the first and third injections.Conclusion: Monthly 1.25mg/0.05ml IVIs of bevacizumab or 0.5mg/0.05ml of ranibizumab for three consecutive months in the treatment of diabetic macular edema does not affect corneal morphology and has no harmful effects on the endothelium.Öğe The Effect of Pupil Dilation on Biometric Parameters of the Lenstar 900(LIPPINCOTT WILLIAMS & WILKINS, 2013) Bakbak, Berker; Koktekir, Bengu E.; Gedik, Sansal; Guzel, HuseyinPurpose: To evaluate the effect of pupil dilation on the biometric parameters of the Lenstar LS 900 (Haag Streit AG, Koeniz, Switzerland). Methods: In this cross-sectional study of 33 eyes with cataracts, axial length (AL), anterior chamber depth, intraocular lens (IOL) power, keratometry, and pupil diameter measurements were performed using Lenstar biometry before and after pupil dilatation. Intraobserver repeatability was assessed by taking 2 consecutive recordings of biometric parameters using Lenstar biometry in the undilated pupils of 30 eyes with cataracts. Results: The mean difference in AL measurements from intraobserver readings was -0.001 +/- 0.01 mm. The study group showed a statistically significant change in the first keratometry reading and anterior chamber depth values (P < 0.05); however, the mean difference in AL and IOL power was statistically insignificant between the undilated and dilated pupil Lenstar biometry readings. Three cases in the study group (9.1%) and 1 case in the control group (3.3%) demonstrated changes in IOL power >0.50 diopter. Conclusions: Dilated and undilated pupil size did not affect the measurement of IOL using the Lenstar biometry.Öğe Effect of Religious Fasting on Tear Osmolarity and Ocular Surface(LIPPINCOTT WILLIAMS & WILKINS, 2014) Koktekir, Bengu Ekinci; Bozkurt, Banu; Gonul, Saban; Gedik, Sansal; Okudan, SuleymanObjective: To evaluate the effects of religious fasting on tear secretion, tear osmolarity, corneal topography, and ocular aberrations. Methods: This prospective controlled study comprised 29 eyes of 29 healthy men. Before ophthalmologic examination, all subjects underwent corneal topography by a placido disc corneal topography and aberrometry device (OPD Scan II). Tear osmolarity was measured using OcuSense TearLab osmometer. Ocular surface disease index (OSDI) scores, tear break-up time (BUT), Schirmer I test, and lissamine green staining were evaluated. The measurements taken before and during Ramadan at the same hours between 4.00 and 5.00 PM were compared using paired sample t test, and a P value less than 0.05 was accepted as statistically significant. Results: The mean age of the study group was 27.8 +/- 5.9 years (range, 20-47 years). The mean tear osmolarity values were measured as 285.6 +/- 8.2 mOsm/L and 293.3 +/- 16.0 mOsm/L, whereas the mean Schirmer I values were 14.8 +/- 6.0 mm and 10.6 +/- 5.3 mm in nonfasting and fasting periods, respectively. Tear osmolarity, OSDI, and Oxford grading scores significantly increased (P=0.02, P=0.002, P=0.003, respectively), whereas Schirmer I values and intraocular pressure decreased (both, P<0.001) during the fasting period compared with the nonfasting period. There were no significant differences in tear BUT, keratometry values, and corneal aberration measurements between nonfasting and fasting periods (P>0.05, for all). Conclusion: Fasting significantly decreases tear production and increases tear osmolarity; however, it does not deteriorate corneal topographic parameters and ocular aberrations in healthy subjects.Öğe The Effect of Room Illumination on the Measurement of Anterior Segment Parameters(LIPPINCOTT WILLIAMS & WILKINS, 2014) Koktekir, Bengu Ekinci; Gonul, Saban; Bakbak, Berker; Gedik, Sansal; Dogan, Omer KamilObjective: To evaluate the effect of room illumination on the measurement of anterior segment parameters. Methods: In this comparative study, measurements of anterior segment parameters of 25 eyes of 25 healthy patients were performed by optical low-coherence reflectometry (OLCR). Measurements were taken under photopic conditions (150 lux) and under mesopic conditions (3 lux). Paired t test by SPSS 16.0 was used to compare the anterior segment measurements performed in both conditions. A P value lower than 0.05 was accepted as statistically significant. Results: The mean age of the patients was 27.09 +/- 1.72 years (range, 20-40 years). Of the anterior segment parameters, axial length and keratometry did not show significant difference between photopic and mesopic conditions (P=0.541 and P=0.812, respectively). The mean anterior chamber depth measurements was 3.04 +/- 0.35 mm and 3.06 +/- 0.35 mm, whereas the mean lens thickness was 3.75 +/- 0.36 mm and 3.77 +/- 0.36 mm in the mesopic and photopic conditions, respectively. The mean pupil diameter measurement was 4.86 +/- 0.70 mm under photopic conditions and 6.36 +/- 0.94 mm under mesopic conditions. The anterior chamber depth, lens thickness, and pupil diameter showed significant difference between photopic and mesopic conditions (P=0.01, P=0.006, and P=0.0001, respectively). Conclusion: Anterior chamber depth, lens thickness, and pupil diameter were affected by the changes in luminance while performing measurements with OLCR. Considering the age of the study group, further studies are needed to test the measurement of accommodation amplitude.Öğe Efficacy of Frequency Doubling Technology Perimetry in Non-arteritic Anterior Ischaemic Optic Neuropathy with Altitudinal Visual Field Defects(INFORMA HEALTHCARE, 2012) Bakbak, Berker; Gedik, Sansal; Koktekir, Bengu Ekinci; Pehlivan, Nimet YapiciThe aim of the study was to evaluate the ability of frequency doubling technology perimetry to detect altitudinal hemifield defects in cases of non-arteritic anterior ischaemic optic neuropathy. Thirty eyes of 24 cases of the disorder with typical altitudinal visual field defects underwent standard automated (Humphrey 24-2) and frequency doubling technology (N-30 threshold) perimetry. For both techniques locations showing a defect of p < 5% were considered abnormal and the mean percentage defect of both the involved and uninvolved hemifields and global visual field parameters were compared. The mean percentage defects for the involved and uninvolved hemifields were comparable (p = 0.1 and p = 0.07, respectively) but there were statistically significant differences in fixation losses and in test duration (p < 0.001 and p < 0.001, respectively) for the two techniques. The authors conclude that frequency doubling technology perimetry is reliable and easily performed in patients with altitudinal visual field defects. The similarity of the extent of visual field defects found using the two techniques suggests that frequency doubling technology perimetry can be used for the rapid detection of altitudinal defects in anterior ischaemic optic neuropathy.Öğe Evaluation of Choroidal Thickness in Non-arteritic Anterior Ischaemic Optic Neuropathy at the Acute and Chronic Stages(TAYLOR & FRANCIS AS, 2016) Gonul, Saban; Gedik, Sansal; Koktekir, Bengu Ekinci; Yavuzer, Kamil; Okudan, SuleymanThe objective of this study was to evaluate the measurements of choroidal thickness (CT) in patients with non-arteritic anterior ischaemic optic neuropathy (NAION) at the acute and chronic stages. This case-control study compares three groups: Group 1 included 23 eyes of 23 patients with chronic NAION, Group 2 consisted of 24 eyes of 24 patients with acute NAION, and Group 3 included 24 eyes of 24 age-matched control subjects. The average CTs for Group 1, Group 2, and Group 3 were 261.24 +/- 50.04, 280.05 +/- 74.94, and 254.74 +/- 50.11 mu m, respectively. For all measurements, no statistical significance was found between the groups (p = 0.319, 0.357, 0.680, and 0.178 for the CTs as average, foveal, superior, and inferior, respectively). Similarly, there was no difference between the CT measurements of the affected and unaffected eyes in Group 1 and Group 2 (p = 0.571, 0.741 for average, respectively). The amount of time after the onset of the disease ranged from 6.0 to 48 months (23.86 +/- 16.70 months) in Group 1 and from 1 to 30 days (7.45 +/- 8.86 days) in Group 2. There was no correlation between the CTs and follow-up times in Group 1 (p = 0.768 for average) and no association between the CTs and the thicknesses of the retinal nerve fibre layers in Group 2 (p = 0.453 for average). CT is not directly influenced by NAION at either the acute or the chronic stage of the disease. These results may also demonstrate that the changes of CT do not increase the risk of experiencing a NAION attack.Öğe Extensive Bone Formation in a Painful Blind Eye(LIPPINCOTT WILLIAMS & WILKINS, 2014) Koktekir, Bengu Ekinci; Karabagli, Pinar; Gonul, Saban; Bozkurt, Banu; Gedik, SansalOsseous metaplasia may occur in phthisis bulbi, usually caused by long-standing retinal detachment, ocular trauma, or inflammation. However, extensive intraocular bone formation is a rare phenomenon. We report a case with long-standing phthisis bulbi demonstrating subretinal extensive bone formation. Results of histopathologic examination revealed extensive bone formation overlying the choroid with accompanying bone marrow without hematopoiesis.Öğe Giant Ethmoido-Orbital Osteoma Presenting with Dacryocystitis and Metamorphopsia(LIPPINCOTT WILLIAMS & WILKINS, 2012) Köktekir, Bengü Ekinci; Öztürk, Kayhan; Gedik, Sansal; Güzel, Hüseyin; Karabağlı, PınarOsteoma is the most common benign neoplasm of the paranasal sinuses. Intraorbital extension is rare. Here we report a 16-year-old adolescent boy who presented with epiphora and pain in the medial canthal area. A computed tomographic scan revealed a bone density mass in the left ethmoid cavity extending into the adjacent orbit. The tumor was removed via endoscopic endonasal surgery. The pathologic evaluation was consistent with osteoma. After surgery, all complaints have been resolved and there was not any sign of recurrence in the computed tomographic scan.
