Papillomacular retinoschisis associated with glaucoma: Response to topical carbonic anhydrase inhibitor

PURPOSE: We report the clinical courses of two patients with papillomacular retinoschisis in eyes with advanced glaucomatous optic neuropathy. OBSERVATIONS: In case 1, a 67-year-old woman was diagnosed with papillomacular retinoschisis and normal tension glaucoma in the left eye. Her medication was switched from topical latanoprost to brinzolamide, resulting in gradual improvement in the papillomacular retinoschisis thereafter. In case 2, a 76-year-old man was diagnosed with papillomacular retinoschisis, foveal detachment, and normal tension glaucoma in the left eye. His medication was switched from topical tafluprost/timolol to brinzolamide, resulting in gradual improvement in the papillomacular retinoschisis and foveal detachment thereafter. CONCLUSIONSAND IMPORTANCE: Papillomacular retinoschisis may occur in eyes with advanced glaucomatous optic neuropathy. Topical brinzolamide therapy may lead to improvement of papillomacular retinoschisis.
