Preretinal fibrosis, also known as cellophane maculopathy or surface wrinkling retinopathy, was diagnosed in this patient.  The patient presented with complaints of metamorphopsia and mild blurring of vision in the affected eye.  Visual acuity was [insert visual acuity, e.g., 20/40] in the right eye and [insert visual acuity, e.g., 20/25] in the left eye.  Funduscopic examination revealed a delicate, glistening, semitransparent membrane on the inner surface of the retina, consistent with preretinal fibrosis.  Optical coherence tomography (OCT) confirmed the presence of a thin, hyperreflective membrane anterior to the retina without significant retinal traction or distortion.  Fluorescein angiography showed no leakage.  Differential diagnosis included epiretinal membrane, macular pucker, and vitreomacular traction syndrome.  The patient's symptoms are currently mild and stable.  Management at this time consists of observation and monitoring for progression.  Patient education regarding the natural history of preretinal fibrosis and potential complications such as macular edema or retinal detachment was provided.  Follow-up examination in [insert timeframe, e.g., 3-6 months] is recommended to assess for any changes in visual acuity or retinal status.  ICD-10 code H35.31 (Preretinal macular fibrosis) is applicable.
