Abstract

Purpose:

This study investigated factors associated with persistent serous retinal detachment in highly myopic eyes with vertical oval-shaped domes.

Methods:

Twenty-eight highly myopic patients (40 eyes) with smooth macular elevations related to a vertical oval-shaped dome were recruited. Serous retinal detachment was investigated; 11 eyes had persistent submacular fluid (study group) and 29 eyes lacked submacular fluid (control group). All patients underwent complete ophthalmologic examinations, including axial-length measurement and fluorescein angiography. Spectral domain optical coherence tomography scans through the fovea measured choroidal thicknesses, macular bulge height, and vitreoretinal interface factors.

Results:

No studied variables (age, sex, spherical equivalence, axial length, vitreomacular traction, epiretinal membrane, and internal limiting membrane detachment) except higher macular bulge height (P = 0.03) and a reduced macular choroidal thickness (P = 0.02) were associated with the risk of serous retinal detachment. No statistically significant differences in best-corrected visual acuity were observed between the study and control groups. Serous retinal detachment always occurred at the top of the inward incurvation of the macula and was characterized by multiple hyperfluorescent granular patches on fluorescein angiography.

Conclusion:

A higher macular bulge height and a reduced macular choroidal thickness might be important factors in the development of serous retinal detachment in patients with vertical oval-shaped domes.
