Abstract

Purpose: To identify the risk factors for myopic foveoschisis among ocular biometries

Methods: We collected 392 highly myopic eyes of 220 patients. High myopia was defined as axial length exceeding 26 mm. Among them, 31 eyes of 25 patients having foveoschisis were included. Retinal curvature was calculated from macula scan of spectral domain optical coherence tomography using customized software. Axial length and anterior chamber depth were obtained using coherence interferometry. Corneal curvature was also measured using keratometry. The parameters were compared between foveoschisis patients and others.

Results: Axial length was significantly longer in the foveoschisis group. (average 29.5 vs 28.0 mm, P = 0.04) Retinal curvature was significantly larger in the affected eyes. (average 0.139 vs 0.095, P = 0.02) Retinal curvature was also larger in the affected eyes compared to axial length matched control group. (average 0.139 vs 0.104, P = 0.04) However, corneal curvature and anterior chamber did not differ between foveoschisis and control group.

Conclusions: Longer axial length and larger retinal curvature were risk factors for the myopic foveoschisis.
