Myopic macular hole detachment associated with intravitreal ocriplasmin
Abstract
Purpose: To describe a case of macular hole retinal detachment in a high myope following intravitreal ocriplasmin injection. Observations: A 71-year-old highly myopic (−18.63 Dioptres) female received 125 μg of intravitreal ocriplasmin (Jetrea, Oxurion, Leuven, Belgium) to treat a right, full-thickness macular hole (FTMH) with vitreomacular adhesion. Presenting best-corrected visual acuity (BCVA) letter score was 45, using the Early Treatment Diabetic Retinopathy Study chart. Past ocular history in the affected, pseudophakic eye included anisometropic amblyopia, but with a documented pre-morbid BCVA of 75 letters. One week post-injection the vitreomacular adhesion persisted. One month post-injection, a large posterior macular hole retinal detachment developed with BCVA of 45 letters. Over the course of one year she underwent three pars plana vitrectomies aiming to treat the retinal detachment and close the FTMH. The detachment was treated successfully but the FTMH persisted, albeit with a reduced diameter. Final BCVA was 55 letters. Conclusions: The pathogenesis of this macular hole detachment may be related to the combination of a FTMH and high myopia. Ocriplasmin functions in a twofold manner; inducing a posterior vitreous detachment and as a proteolytic enzyme digesting the fibronectin and laminin at the pathological vitreoretinal interface. With access through a FTMH, ocriplasmin may exert an enzymatic effect on the interphotoreceptor matrix and the photoreceptor-retinal pigment epithelium interface that normally helps maintain neuroretinal adhesion to the retinal pigment epithelium. The reported increase in basal diameter of FTMHs following ocriplasmin supports this hypothesis. High myopia was another likely contributing factor. Highly myopic patients were excluded from the initial ocriplasmin registration studies, mainly due to the risk of retinal detachment, but were eligible for subsequent large trials. Importance: Clinicians should be aware of a potential association between ocriplasmin and macular hole detachments in eyes with high myopia.
