Abstract:
Objective To investigate the characteristics of optical coherence tomography (OCT) in eyes with repaired idiopathic macular hole (IMH) after operation and the relation with recovery of visual acuity. Methods The characteristics of OCT images of 24 patients (25 eyes) with repaired IMH after vitrectomy,internal limiting membrane(ILM)peeling and auto-serum healing were analyzed retrospectively. In the patients with IMH, the macular hole was found in 9 eyes at stage Ⅱ, 13 eyes at stage Ⅲ, and 3 eyes at stage Ⅳ. Examinations of best-corrected visual acuity, slit-lamp biomicroscopy with fundus contact lens, fundus photography, fundus fluorescein angiography(FFA) and OCT were performed on the patients 3 to 24 months after surgery. Results OCT images of the repaired IMH were categorized into 3 patterns: U-type (5 eyes) with relative normal foveal contour; V-type (7 eyes) with steep foveal contour;W-type (13 eyes) with foveal defect of neurosensory retina, but without warped hem of retinal hole or cystic formation. Postoperative visual acuities were improved in all of the patients and the best ones were in group U-type. Conclusion Characteristics of OCT images of repaired IMH may be related to the postoperative visual acuity.
