    Do daily wear opaquely tinted hydrogel soft contact lenses affect contrast sensitivity function at one meter?
    (2003) Özkağnıcı, A.; Zengin, N; Kamış, Ü.; Gündüz, K.
    Purpose. To investigate the effects of daily wear opaquely tinted hydrogel soft contact lenses on contrast sensitivity functions, as measured using the Pelli-Robson chart viewed at 1 meter. Methods. Contrast sensitivity was measured in 48 healthy individuals before and 6 hours after soft contact lens wear. Twenty-four subjects used clear soft contact lenses and 24 used tinted soft contact lenses. Results. The contrast sensitivity scores were significantly decreased monocularly and binocularly (P= 0.000 and P= 0.002, respectively) in the colored contact lens group whereas there were no significant changes in the clear contact lens group (P = 0.317 and P = 0.317, respectively). Conclusions. Color-tinted contact lenses were associated with a reduction of contrast sensitivity function. Therefore, those who wear colored contact lenses should be informed about the possible consequences of tinted contact lens wearing. © 2003 Contact Lens Association of Ophthalmologists, Inc.

    Tear film and meibomian gland functions in psoriasis
    (SCRIPTOR PUBLISHER, 1996) Zengin, N; Tol, H; Balevi, S; Gunduz, K; Okudan, S; Endogru, H
    Tear secretion, tear film stability, and meibomian gland function (plugging, volume, and thickness) were assessed;in patients with psoriasis vulgaris (n = 70), As compared to that of the healthy controls (n = 125) mean Schirmer I value of psoriatic patients was found to be in normal ranges, whereas tear film break-up time was significantly lowered. When evaluating meibomian gland function, psoriatic patients were found to have higher plugging and thickness indices but a normal volume of meibomian gland secretion, These findings suggested an obstructive type of meibomian gland dysfunction in psoriatic patients which might result from increased turnover of the epithelia lining the meibomian gland duct.
