Management of neovascular glaucoma related to the persistence after retinal detachment surgery of a circumferential peripheral retinal detachment

OBSERVATION: A 41-year-old male with a medical history of high myopia and several retinal detachment (RD) surgeries was referred for vitreous hemorrhage coexisting with neovascular glaucoma occurring 2 months after uncomplicated silicone oil removal on his left and single eye. The right eye had been lost to RD. The retina behind the equator was reattached on ultrasonography. We performed a washout pars plana vitrectomy on the left eye, revealing a chronic circumferential RD of the anterior retina stopped in its posterior spread by dense photocoagulation scars. We combined a retinectomy of the detached retina with an intracamerular injection of bevacizumab, resulting in complete disappearance of rubeosis and normalization of the intraocular pressure. CONCLUSIONS: The retinal ischemia related to the persistence of a chronic and circumferential RD anterior to dense photocoagulation scars after ab-interno RD surgery, whereas the rest of the retina appears reattached, is probably the causative factor of neovascular glaucoma. In the present case, the removal of RD by circumferential retinectomy combined with an intraocular injection of anti-VEGF allowed the complete and definitive regression of neovascular glaucoma.
