    Anatomic and functional results of macular hole surgery with silicone oil tamponade
    (2013) Bakbak B.; Öztürk B.T.; Gönül S.; Gedik S.
    Purpose: To review the anatomical and visual outcomes in patients who underwent macular hole surgery with silicone oil tamponade. Materials and Methods: A retrospective review of 21 patients who had undergone macular holes surgery with silicone oil tamponade was conducted The primary outcome variables include best-corrected visual acuity (BCVA) in Early Treatment of Diabetic Retinopathy Study (ETDRS) letters and optical coherence tomography changes in eyes with a macular hole after the surgery. Results: The median age of 21 patients was 58.32 years. Thirteen patients had Stage 3 macular holes and eight patients had Stage 4 macular holes. Anatomical closure rate was achieved in 90.4% (19/21) of all patients. The median preoperative BCVA was 31.2 ETDRS letters (range: 13-52 letters), which increased to 42.9 ETDRS letters (range: 27-74 letters), six weeks following the removal of the silicone oil. Conclusion: Our study with 21 patients indicates that the use of silicone oil tamponade in macular hole surgery showed satisfactory anatomical and functional outcomes. As an alternative to gas tamponade, silicone oil can be used for primary macular hole surgery in patients that are unable to position themselves in a face-down posture after surgery.

    Bilateral adie's tonic pupil [Bilateral adie'Nin tonik pupillası]
    (Turkish Ophthalmology Society, 2013) Bakbak B.; Ekinci B.K.; Gedik S.; Yavuzer K.; Öztürk B.T.
    A 37-year-old male patient applied with the complaint of photophobia and having difficulties in reading. Both pupils were found to be dilated and un reactive to light but responsive to accommodation. The case was diagnosed with bilateral tonic pupil following neurological, radiological and laboratory evaluations. Tonic pupil should be kept in mind in eyes with light-near dissociation. In this case report, bilateral tonic pupils and the possible mechanism which may cause this disorder were discussed.

    Granulomatous anterior uveitis, internal ophthalmoplegia, and retinal vasculitis during chickenpox disease in a child [Suçiçe?i geçiren bir çocukta granülomatöz ön üveit, İnternal oftalmopleji ve retinal vaskülit]
    (2013) Donbalo?lu M.; Bozkurt B.; Kerimo?lu H.; Öztürk B.T.
    Herein, we report the case of a patient who had granulomatous anterior uveitis, internal ophthalmoplegia, and retinal vasculitis during chickenpox disease. A 9-year-old girl was admitted to our clinic with blurred vision and hyperemia in the right eye. Corrected visual acuity was 20/20 in both eyes. Direct/indirect pupillary reactions were negative in the right eye and pupil was dilated. Biomicroscopic examination revealed middle-sized granulomatous keratic precipitates and a severe anterior chamber reaction. Fundus examination was normal. As there were red papules all over the body she was diagnosed as anterior uveitis secondary to chickenpox and systemic/topical acyclovir, topical steroid, antihistaminic suspension, isolation, and follow-up were recommended. On day 6, anterior chamber inflammation decreased remarkably, whereas a salt-pepper appearance was observed in the retina. On day 10, a perivascular sheathing was observed, which regressed after 1 month, and her medications were slowly tapered and discontinued. Although anterior uveitis is a common finding after chickenpox, the occurrence of three different involvements is very rare.

    Optical coherence tomography findings in bietti crystalline retinopathy [Bietti Kristalin Retinopatisinde Optik Koherens Tomografi Bulgular?]
    (2011) Öztürk B.T.; Bozkurt B.; Kamíş Ü.; Oka M.
    Optical coherence tomography (OCT) findings of two patients with Bietti crystalline retinopathy were evaluated. The fundus examination of patients who admitted to our clinic with the complain of decreased visual acuity, revealed diffuse crystalline deposits and retinal pigment epithelial atrophy at the posterior pole. In OCT, high reflective foci, thickening and increased reflectance of the retinal pigment epithelium-choriocapillaris complex were observed. These cases demonstrate that OCT is an adjunctive tool for the follow-up of crystalline deposits and atrophy of the retinal pigment epithelium in Bietti crystalline retinopathy.

    Spectral domain optical coherence tomography findings in posterior microphthalmia [Posterior mikroftalmide spektral domain optik koherens tomografi bulgulari{dotless}]
    (Turkish Ophthalmology Society, 2014) Kayitmazbatir E.T.; Öztürk B.T.; Kerimo?lu H.; Özka?nici A.; Okudan S.
    The retinal spectral domain optical coherence tomography (SD-OCT) findings of two posterior microphthalmia cases are presented in this case report. For this purpose, the findings of two siblings aged five and seven years who presented to our clinic with the complain of far-sightedness and high hypermetropia were evaluated. Both cases diagnosed to have posterior microphthalmia demonstrated normal biomicroscopic anterior segment examination and gonioscopy findings and the axial lengths were measured to be shorter than 17mm. The SD-OCT analysis of papillomacular folds detected in fundus examination revealed contribution of only neurosensorial retina. Beneath the retinal fold, we observed bilateral cysts in the intraretinal area in one of the cases and a triangle-shaped hyporefective space with an apex corresponding to that of the retinal fold in the subretinal area in both cases. SD-OCT is an adjunctive imaging tool for diagnosis and follow-up of degenerative changes in posterior microphthalmia. These changes may be also important for visual prognosis.

    Spontaneous closure of macular hole induced by accidental Nd: YAG laser injury
    (2013) Bakbak B.; Gedik Ş.; Öztürk B.T.; Kerimoglu H.
    The natural history of Neodymium:yttrium aluminum garnet (Nd:YAG) laser-induced macular holes remains uncertain because this type of injury is uncommon. A 47 years old male physicist with the diagnosis of macular hole induced by accidental Nd:YAG laser injury was followed-up. The size of the macular hole decreased and vitreous hemorrhage resolved spontaneously. Accidental exposure to high-energy Nd:YAG laser may lead to concussive retinal damage and create a macular hole. Laser-induced macular holes can resolve spontaneously. The presence of an epiretinal membrane and the size of the macular hole are the common ocular signs that seem to affect the natural course of laser-induced macular holes.

    Transscleral diode laser cyclophotocoagulation in refractory glaucoma [Dirençli glokom olgularında transskleral diod lazer siklofotokoagülasyon]
    (Turkish Ophthalmology Society, 2013) Bitirgen G.; Okka M.; Bozkurt B.; Do?ru I.; Kerimo?lu H.; Öztürk B.T.; Kamiş U.
    Purpose: To evaluate the safety and efficacy of transscleral diode laser cyclophotocoagulation (TSDLC) in advanced glaucoma refractory to medical or surgical treatment. Material and Method: The data of subjects who were treated with TSDLC between 2009 and 2011 were retrospectively reviewed. Intraocular pressure before and after treatment, visual acuity, the number of medications and complications were analysed. Success was defined as final IOP of 6-22 mmHg with or without antiglaucomatous medications. Results: Thirty seven eyes of 37 patients were included in the study. Mean age of patients and mean follow-up time were 61.73±17.13 years (range: 19-80 years) and 8.06±5.81 months (range: 3-22 months), respectively. Mean pretreatment IOP was 38.68±8.94 mmHg and IOP was 26.46±11.34 mmHg (p <0.01) at the second week, whereas it was 24.97±10.84 mmHg (p<0.01) at the last visit. IOP of less than 22 mmHg was achieved in 40.5% of eyes at the last visit. Mean treatment number per eye was 1.48±0.73, and more than one treatment was required in 13 (35.1%) eyes. Preoperative and postoperative mean total antiglaucomatous medications were 3.14±1.18 and 2.76±1.23, respectively. No phthisis bulbi or persistent hypotonia developed during the follow-up period. Discussion: TSDLC is an effective and safe method for the treatment of refractory glaucoma. It also served to reduce the number of antiglaucoma medications, thus improving both the quality of life of the patients and their compliance to therapy. © Galenos Yayinevi.
