To describe the clinical features and optical coherence tomography (OCT) findings of highly myopic eyes with posterior staphyloma.
A retrospective review of all patients with high myopia (≥-8.0D) and posterior staphyloma underwent biomicroscopy, OCT examination and met the study inclusion criteria at the Linkou Chang Gung Memorial Hospital was performed. The data recorded from the patients included age, gender, refractive status,, best-corrected visual acuity. The relationships between the presence of macular retinoschisis and age, refractive error, visual acuity were compared.
111 eyes of 57 patients (37 female, 20 male), aged from 28 to 80 years (mean, 51.6 years) were included in the study. There were 40 eyes (36.04%) with abnormal OCT finding that included outer retinoschisis, inner retinoschisis, macular hole, foveal detachment. 2 cases of macular retinoschisis proceeded with spontaneous resolution during following up. There were no significant difference between the incidence of retinoschisis and age (P-value: 0.444, t-Test), refractive status (P-value: 0.600, t-Test) in these highly myopic eyes.
Macular retinoschisis is not uncommon in highly myopic eyes with posterior staphyloma and is well demonstrated by OCT. The major cause of decreased visual acuity was the development of foveal detachment during the follow-up period.
