    Meibomian Gland Dysfunction and Tear Film Abnormalities in Rosacea
    (LIPPINCOTT-RAVEN PUBL, 1995) Zengin, N.; Tol, H.; Gündüz, K.; Okudan, S.; Balevi, S.; Endoğru, H
    In order to determine the relationship between meibomian gland dysfunction and tear film abnormalities in rosacea, tear film flow and stability and meibomian gland function were assessed in 43 consecutive patients. Schirmer, tear film break-up time, and meibomian gland function values in patients with ocular rosacea (n=28) were found to be significantly decreased as compared with those of the patients with only cutaneous involvement and control patients (p>0.05). In patients with dermatologic rosacea (n=15) these values were not different from those of the age- and sex-matched controls (p>0.05). The effects of tetracycline and meibomian gland expression therapy were also investigated in patients with ocular rosacea. Neither meibomian gland expression therapy nor tetracycline administration had beneficial effects on decreased tear secretion, but tetracycline improved the break-up time values. Our findings showed a positive relationship between tear film abnormalities and meibomian gland dysfunction in patients with rosacea. Decreased tear secretion in patients with ocular rosacea would seem to be a result of structural changes secondary to meibomian gland dysfunction, and short break-up time might be due to an abnormal meibum composition.

    Ocular and Periorbital Anthropometric Measurements in Term Turkish Newborns
    (SPRINGER FRANCE, 2001) Özkağnıcı, A.; Büyükmumcu, M.; Zengin, N.; Gündüz, K.; Koç, H.
    This study was conducted in an effort to determine the normal landmarks in the eyelids and eyebrows of newborns and the relationships between them. We also correlated all measurements with gender and head circumferences. The anthropometric measurements were performed on 86, normal term newborns (40 mates and 46 females) in the first 48 hours after delivery. There was no significant difference between either sex, or between the right and left eyes. In contrast, a statistically significant positive correlation was found between the head circumference and the horizontal fissure length (r = 0.42, p < 0.01). In addition, a significant correlation was found between the upper eyelid crease distance and the horizontal and the vertical fissure lengths (r = 0.27, p < 0.01; r = 0.22, p < 0.05, respectively). The results indicate that the normal eyelid crease location may be used as a landmark for guidance to plan surgical and reconstructive procedures.
