Background And Objective:
Macular anatomic abnormalities in high myopia are more frequent in the presence of posterior staphyloma. The objective was to determine the prevalence of foveoschisis, foveal detachment, vascular traction, epiretinal membrane (ERM), and macular hole (MH) in eyes with high myopia by spectral-domain optical coherence tomography.
Patients And Methods:
Prospective, observational study. Eyes with myopia greater than 8 diopters (D) were included. Results were analyzed using chi-square and Student's t tests.
Results:
The study included 116 eyes of 72 patients. Mean spherical equivalent: -15.04 ± 5.33 D. Mean axial length: 28.88 ± 2.31 mm. Foveoschisis was observed in 17 eyes (14.65%), vascular traction in 17 (14.65%), ERM in 13 (11.2%), lamellar MH in two (1.72%), and posterior staphyloma in 41 (35.34%). Presence of foveoschisis, vascular traction, and ERM was more frequent in eyes with posterior staphyloma (P = .0001).
Conclusion:
Macular anatomic abnormalities were observed in 22.41% of eyes with high myopia and in 53.65% of eyes with posterior staphyloma.
