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.
