Özet

Objective: The aim of the present study was to represent thelong term follow-up of unilateral keratoconus (KC) patients with rotatingScheimpflug camera. Material and Methods: Medical records of 919 KC follow-up patients were reviewed. A total of 16 patients with at least 12 monthsof follow-up period were recruited. The KC positive eyes constituted the “KCgroup”, normal fellow eyes constituted the “fellow eye group”, and 24 eyes of24 normal age-matched subjects “control group”. All subjects underwent acomplete ophthalmologic examination and were evaluated by rotatingScheimpflug imaging system. Also, 9 patients with at least 36 months of follow-up were evaluated separately. Results: The mean ages of KC and controlgroups were 30.38±9.34, 31.62±8.49, respectively (p= 0.664). The mean follow-up time in KC and control groups were 38.13±38.86 and 13.45±2.08, respectively.Demographic factors were similar between groups. At baselineexamination, keratometry values , inferior superior difference at 4 mm (I-S),topometric indices and corneal thickness at apex and the thinnest point weresignificantly different between KC group and fellow eye group (p<0.05 for allcomparisons). In the longer follow-up of 9 eyes in KC group for a mean of59.67±26.68 months, KC progressed in 2 eyes, however the fellow eyes ofthese 9 remained stable. Conclusion: Although KC is known to be asymmetricalbut bilateral, unilateral diseases might also be detected. Follow-up of unilateralKC patients is important to discrimiate asymmetrical keratoconus, whichrequires early progression analysis for crosslinking decision to protect better visionfrom really healthy fellow eyes that do not need intervention.
