RESUMEN
Retinal pigment epithelial (RPE) tear has been described to occur spontaneously, after laser photocoagulation and in recent times, after intravitreal injection of anti-vascular endothelial growth factor (VEGF) agents. In the latter case, the rapid contraction of the choroidal vascular membrane underneath a serous RPE detachment is believed to be the underlying cause. Preservation of good visual acuity after the occurrence of RPE tear with continued use of intravitreal VEGF agents has been reported. In this case report, we describe the occurrence of multiple RPE tears with the use of intravitreal bevacizumab and also correlate the preservation of visual acuity with features seen on spectral domain optical coherence tomography.

Incarceration of vitreous in sclerotomy sites during pars plana vitrectomy can lead to wound-related complications similar to vitreous incarceration in cataract surgery. We describe an illuminated curved 25-gauge vitrectomy probe for removing vitreous from sclerotomy sites. Polyester tubing is used to secure a fiber optic endoilluminator (0.5 mm) with the curved 25-gauge vitrector (0.5 mm). The resultant illuminated curved vitrector (20 G) has a diameter of 1.0 mm. It facilitates complete removal of vitreous around the internal sclerotomies under direct visualization in both phakic and pseudophakic eyes. The same was confirmed with ultrasound biomicroscopy of the sclerotomy sites. Curved vitrector reduces postoperative complications related to incarcerated vitreous in phakic and pseudophakic eyes and other sclerotomy-related wound complications.
