A man in his early 50s had severe primary open-angle glaucoma and proliferative diabetic retinopathy in both eyes, for which he underwent panretinal photocoagulation. His intraocular pressures were well-controlled after trabeculectomies, and his optic nerves appeared stable. However, he was noted to have progressive superior visual field loss in both eyes (Figure, A). He subsequently underwent bilateral upper eyelid levator advancement with blepharoplasty for worsening ptosis. One week following surgery, his visual fields improved (Figure, B).
