Description
Summary:Purpose To describe the clinical implications of outer foveolar defects on optical coherence tomography (OCT) in eyes treated surgically for macular hole (MH). Design Retrospective observational case series. Methods Ninety-six eyes of 93 subjects who had undergone surgery for the treatment of idiopathic MH were included. Clinical data, including OCT prior to and at follow-up visits ranging from 3 to 32 months after surgery, were analyzed. Incidence, risk factors, and clinical outcomes of outer foveolar defect were evaluated. Results Outer foveolar defects were noted on postoperative OCT in 44 of the 96 eyes (45.8%). The mean preoperative diameter of MH in the eyes (333.5 ± 126.3 μm) evidencing outer foveolar defects was significantly smaller than those that did not (504.2 ± 155.6 μm) ( P < .0001). The mean disappearance time of the defect was estimated to be 182 days after surgery. The mean postoperative visual acuity (logMAR) improved to 0.40 ± 0.26 from 0.58 ± 0.23 after the disappearance of outer foveolar defects. Conclusions Outer foveolar defects were detected predominantly after surgery for small MHs. The defect decreases gradually in size and eventually disappears completely approximately 6 months after surgery.
