A paradigm shift in the treatment of refractory angle closure glaucoma in a patient with X-linked juvenile retinoschisis

Abstract

ABSTRACT Background X-linked retinoschisis (XLRS) is a rare inherited bilateral retinal degeneration caused by mutations in RS1 gene, occurring exclusively in men. Various ocular complications associated with XLRS are reported, and angle closure glaucoma in these eyes is one such complication that is refractory and needs surgery for intraocular pressure control. Glaucoma surgery in these eyes often results in refractory malignant glaucoma with its serious sequelae. Several surgical modifications to prevent this complication have been tried with no or limited success. Methodology In this report, we present a case of XLRS in a young male with a 22-year follow-up. We have described the natural history and progression of retinal disease and glaucoma. Results Refractory angle closure glaucoma in our patient was treated with core vitrectomy, phacoemulsification with intraocular lens implantation, and irido-zonulo-hyaloido-vitrectomy. This helped in successful deepening of anterior chamber, good IOP control, and preventing malignant glaucoma. Conclusion Our case highlights the role of vitrectomy in managing the secondary angle closure glaucoma in eyes with X-LRS.
