Abstract
Objective: To investigate the central corneal thickness (CCT) in the central retinal vein occlusion fellow eye (CRVO-fellow eye) patients. Material and Method: A cross-sectional study with 97 CRVO-fellow eye patients and 112 healthy subjects. Three measurements of CCT were obtained with ultrasonic pachymetry. Results: Mean age of CRVO-fellow eye was higher than controls, 59.7 ±10.3 vs. 46.4 ± 5.8 years, (p < 0.001). Males were more prevalent in CRVO-fellow eye than in the controls, 47.4% vs. 25%, (p = 0.001). In CRVO-fellow eye group, systemic diseases were more prevalent. Glaucoma and ocular hypertension were detected in 23 eyes (23.7%) of CRVO-fellow eye. Mean CCT of CRVO-fellow eye was thinner than controls, 529.2 ± 30.3 vs. 543.3 ± 31.8 μm, (p = 0.001). Multiple linear regression models adjusted for age, sex, diabetes, hypertension, cup-to-disc ratio, IOP, and axial length revealed that mean CCT of CRVO-fellow eye was 16.9 μm thinner than controls. Conclusion: CRVO-fellow eye patients have thinner CCT than controls. The pathophysiology of this association is unclear. It may be related to less lamina cribosa rigidity in the thin corneal eye. Lamina cribosa displacement may compress central retinal vein, leading to CRVO.
