Özet
Objective: The aim of the present study was to represent the long term follow-up of unilateral keratoconus (KC) patients with rotating Scheimpflug camera. Material and Methods: Medical records of 919 KC fol- low-up patients were reviewed. A total of 16 patients with at least 12 months of follow-up period were recruited. The KC positive eyes constituted the “KC group”, normal fellow eyes constituted the “fellow eye group”, and 24 eyes of 24 normal age-matched subjects “control group”. All subjects underwent a complete ophthalmologic examination and were evaluated by rotating Scheimpflug imaging system. Also, 9 patients with at least 36 months of fol- low-up were evaluated separately. Results: The mean ages of KC and control groups were 30.38±9.34, 31.62±8.49, respectively (p= 0.664). The mean fol- low-up time in KC and control groups were 38.13±38.86 and 13.45±2.08, re- spectively. Demographic factors were similar between groups. At baseline examination, keratometry values , inferior superior difference at 4 mm (I-S), topometric indices and corneal thickness at apex and the thinnest point were significantly different between KC group and fellow eye group (p<0.05 for all comparisons). In the longer follow-up of 9 eyes in KC group for a mean of 59.67±26.68 months, KC progressed in 2 eyes, however the fellow eyes of these 9 remained stable. Conclusion: Although KC is known to be asymmet- rical but bilateral, unilateral diseases might also be detected. Follow-up of uni- lateral KC patients is important to discrimiate asymmetrical keratoconus, which requires early progression analysis for crosslinking decision to protect better vi- sion from really healthy fellow eyes that do not need intervention.
