History |
A 58 year old woman with a history of metastatic parotid adenocarcinoma presented with bilateral vision loss over 2 months. She had undergone surgical resection of the tumor followed by fractionated external beam radiation with a total of 66.6 Gy 18 months prior to presentation. She was recently found to have metastatic disease involving V3 and Meckel's cave on the left. On initial exam, her vision was 20/125 right eye, 20/50 left eye, without APD. She had reduced color vision in both eyes (2.5/14 right eye, 3/14 left eye). She had a left facial droop secondary to her parotid resection with resulting mild exposure keratopathy in the left eye. Posterior segment exam was unremarkable. Perimetry was normal in the left eye and showed superior/central depression in the right eye. The day following initial evaluation she underwent stereotactic radiosurgery to her left middle cranial fossa lesion, with a total dose of 2.12 Gy to the left optic nerve. Her vision loss progressed to counting fingers in the right eye and 20/200 in the left eye over the following month and at last follow-up was 8/200 right eye and 4/200 left eye. |
