To investigate factors associated with persistent serous retinal detachment in highly myopic eyes with vertical oval-shaped dome.
Cross-sectional study from the University Medical School of Málaga and Santiago de Compostela.
Twenty nine highly myopic patients (41 eyes) presenting with smooth macular elevations related to a vertical oval-shaped dome were recruited. The eyes were characterized as having or lacking a serous retinal detachment: 11 eyes had persistent submacular fluid (study group), and 30 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 were performed to measure the choroidal thicknesses, macular bulge height and vitreoretinal interface factors.
No studied variables (age, sex, spherical equivalence, axial length, vitreomacular traction, epiretinal membrane, internal limiting membrane detachment) except higher macular bulge height (p=0.03) and a reduced macular choroidal thickness (p=0.02) were associated with a risk of serous retinal detachment, and no statistically significant differences in the best-corrected visual acuity were observed between the study and control groups. The serous retinal detachment always occurred at the top of the inward incurvation of the macula and was characterized by multiple hyperfluorescence granular patches on fluorescein angiography.
A higher macular bulge height and a reduced macular choroidal thickness might be an important factor in the development of serous retinal detachment in patients with vertical oval-shaped dome.
