Pathology Associated with Optical Coherence Tomography Macular Bending due to either Dome-Shaped Macula or Inferior Staphyloma in Myopic Patients

PURPOSE: To evaluate the prevalence of and describe the pathology associated with macular bending (MB) defined as a smooth macular elevation found in optical coherence tomography (OCT) of patients with high myopia related to either dome-shaped macula (DSM) or the border of an inferior staphyloma. PROCEDURES: We reviewed the 330 files of all highly myopic patients in our database that had had an OCT performed in the last 5 years. Main outcome measures were MB prevalence and its associated pathology. RESULTS: Sixty-eight eyes from 45 patients (13.63%) presented MB; 23 bilateral, 40 in a posterior pole or macular staphyloma and 21 in an inferior staphyloma. Eighteen eyes presented choroidal neovascularization (CNV), 7 subretinal fluid without CNV, 11 retinoschisis and 3 a macular hole which had been stable for years. No differences were found in the rate of complications between patients with DSM or inferior staphyloma. CONCLUSIONS: MB is not an uncommon clinical feature. Associated pathology prevalence in MB was elevated and similar in posterior and inferior staphylomas.
