Zusammenfassung:To evaluate the association of axial length and posterior segment length with central retinal vein occlusion (CRVO) using optical coherence interferometry. The study group consisted of 29 patients (13 female and 16 male) with unilateral CRVO who were referred to Farabi Eye Hospital. Patients with macular edema were excluded. The mean keratometry (mean K), axial lengths (AL), anterior chamber depths (ACD), and posterior segment lengths (PSL, defined by AL - ACD) of affected and fellow eyes were measured using optical coherence interferometry. Age range was 45 to 74 years (mean 59.2 +/- 7.5 years). The mean K of affected eyes was not statistically significantly lower than that of unaffected eyes in the CRVO group. This was also true for ACD. Although affected eyes had shorter axial length (23.26 mm vs 23.33 mm), the difference was not significant. There was a statistically significant difference in PSL affected and unaffected eyes (20.15 mm vs 20.26 mm) (p=0.008). Posterior segment length of eyes with CRVO may be shorter than unaffected eyes. This may predispose them to more crowding of central retinal vein and artery in lamina cribrosa, and developing CRVO.
