In patients with a unilateral full-thickness macular hole, fellow eyes with a foveolar detachment, perifoveal posterior vitreous detachment or inner foveal splits may have an increased risk for progression to macular hole, according to a study.
The retrospective observational case series included 176 patients with a unilateral full-thickness macular hole. Forty-two fellow eyes of 42 patients were found to have a perifoveal posterior vitreous detachment.
After an average follow-up of 18.2 ± 13 months, 16 eyes had a foveolar detachment, of which nine had concurrent inner foveal splits. Four eyes had a foveal pseudocyst only, the study said.
After 2 years of additional follow-up, a second full-thickness macular hole was observed in five of 16 fellow eyes with a foveolar detachment and five of nine fellow eyes with a foveolar detachment and inner foveal splits.
Of the four eyes with a foveal pseudocyst, two developed vitreofoveal separation without hole formation, and two eyes remained stable, the study said.
