Intraoperative Drainage of a Bullous Serous Pigment Epithelial Detachment

Abstract

To describe a novel, simple technique for surgically draining a bullous serous pigment epithelial detachment (PED). Pars plana vitrectomy was performed with confirmed elevation of the hyaloid face. Proportional diathermy allowed stepwise entry into the PED superotemporally through an initially small, needle-point focus while providing control of any potential bleeding. Thick fluid was aspirated with a soft-tipped cannula, fluid-air exchange was performed, and intravitreal bevacizumab was injected before removing the cannulas. The PED was successfully completely drained intraoperatively and remained flat at 1 week postoperatively. However, the draining site ultimately closed, and continued exudation from choroidal neovascularization led to recurrent PED and eventual nonhemorrhagic retinal pigment epithelial tear despite aggressive treatment with aflibercept and photodynamic therapy. The early visual acuity benefit may relate to resolution of hyperopic shift. Serous PED can be surgically reduced without hemorrhagic complications, but long-term success depends upon control of the underlying choroidal neovascularization.
