Abstract Details

Purpose:

To evaluate and describe the vitreo-retinal interface changes on spectral domain optical coherence tomography (SD-OCT) in the fellow eyes of patients with idiopathic full thickness macular holes (FTMH) with indication for surgery or idiopathic lamellar macular holes (LMH).

Setting:

Hospital Garcia de Orta E.P.E. (Almada/Portugal)

Methods:

Patients with idiopathic FTMH in one or both eyes which underwent surgical repair or who were awaiting surgery and patients with idiopathic LMH observed at our centre between January 2010 and December 2013 were evaluated retrospectively. Demographic details, best corrected visual acuity and results of SD-OCT of the primary and fellow-eye were evaluated. Exclusion criteria for this study included refractive error less than -3 diopters (D) or more than +3D, amblyopia, glaucoma, history of uveitis, ocular trauma or tumor, ocular surgery (in the fellow eye), choroidal neovascularization, diabethic retinopathy or any associated systemic disorders that might affect the eye.

Results:

Twenty-five patients were included in the study. 9 (36%) were males and 16 (64%) were females with an average age was 67,6±8,7years. Macular holes of the primary-eye were lamellar in 7 patients (28%), full thickness grade III in 5 patients (20%) and grade IV in 13 patients (52%). On the contralateral eyes, foveal contour was classified as normal in 13 eyes (52%) and abnormal in 12 (48%). The vitreo-retinal interface changes in the fellow-eye were: FTMH in one eye (4%), vitreomacular traction with edema in four eyes (16%), epiretinal-membrane (ERM) in nine eyes (36%) and LMH in two eyes (8%). Two eyes had an ERM and a LMH and two eyes had an ERM and vitreo-macular traction. Central-foveal-thickness was low (below the fifth percentile of the software database) in 8 eyes (32%). Posterior vitreous detachment was present in 9 eyes (in 6 eyes with normal and 3 with abnormal foveal contour). Visual acuity was equivalent in eyes with normal or abnormal foveal contour (p=0,68). There was no statistical correlation between the grade of the FTMH or LMH and the presence of fellow eye vitreo-retinal interface changes (p=0,25). No difference was observed in choroidal thickness of the primary or contralateral-eye (p=0,12).

Conclusions:

As previous studies have suggested, patients with idiopathic macular holes have a considerable risk of presenting vitreo-retinal interface changes in their contralateral eye. An early SD-OCT should be considered for detection of these fellow-eye changes, even if the visual acuity is normal. Patients with idiopathic LMH must also be evaluated, as both patients with idiopathic FTMH or idiopathic LMH seem to present an equal risk for the development of vitreo-retinal interface changes.
