A 32-year-old female presented with visual acuity of hand movement close to face, an old inferior rhegmatogenous retinal detachment (RRD), and a large hemorrhagic macular macrocyst (HMM) in the right eye. After 2 weeks of successful vitreoretinal surgery, the HMM started decreasing in height and resolved by 3 months. On optical coherence tomography, a zone of hyperreflectivity in the outer retinal layers was evident on resolution of the cyst. At final follow-up, the visual acuity improved to 1/60 only. Though HMM resolved completely after retinal reattachment, alteration and thickening of microarchitecture of the outer retinal layers ensued.
