Herein, we report a case of acquired optic nerve pit in a 46-year-old Indian male, a known case of primary angle closure glaucoma (PACG) compatible with treatment for the past 15 years. He presented to our clinic with complaints of recent decrease in vision; on examination, his visual acuity was found correctable to 6/6 and 6/12 in the right and left eye, respectively. Fundoscopy revealed glaucomatous cupping in both the eyes and subretinal fluid in macula of the left eye. Swept-source optical coherence tomography macula and retinal nerve fiber layer disclosed acquired pit of the optic nerve (APON) in the left eye. The patient was under continuous follow-up and maculopathy spontaneously resolved. An APON may indicate progression of glaucoma and was more commonly reported in cases of primary open-angle glaucoma; we aimed to report an unusual presence of APON in a case of PACG.
