| History |
A 66-year-old woman presented with a four-month history of insidious bilateral visual loss. Ophthalmologic examination revealed visual acuity reduced to finger counting in both eyes. On fundus examination, maculae and optic discs appeared normal. Visual fields showed bilateral central scotoma with mainly nasal defects. Past medical history was extensive including type 2 diabetes and coronary artery disease with myocardial hypertrophy. Surgical history included bilateral hip replacements with revision on the left. Review of systems was notable for recurrent depression, fatigue and decreased appetite with weight loss. She also complained of paresthesias in her hands and feet, imbalance, and bilateral hearing loss. Electroretinography (ERG) revealed severe cone dysfunction. Based on the clinical and ERG findings, cancer-associated retinopathy (CAR), melanoma-associated retinopathy (MAR) or autoimmune retinopathy (AIR) was suspected. An extensive tumor screening including brain MRI, FDG-PET-CT and anti-CNS antibodies (including anti-recoverin for CAR) did not reveal any small-cell lung carcinoma, gynecologic tumor, melanoma or other malignancy. Autoimmune screening was negative. Two years after first presentation, the patient consulted an orthopedic surgeon because of chronic left hip pain and muscle tenderness after hip replacement surgery. A diagnostic test was performed. |
