Clinical Presentation

A 42-year-old man was evaluated for blurred vision in the left eye. He stated that the blurred vision came on gradually over 6 months and was painless, and that the right eye had no problems. He was seen 3 months after the symptoms began and was given a new glasses prescription. He was told that only the prescription of the left eye had changed.

The patient had a history of hyperlipidemia and was taking atorvastatin. He does not drink alcohol or smoke tobacco. There is no family history of vision loss.

Best-corrected visual acuity (-1.25 D sphere in the right eye and -0.50 D sphere in the left eye) was 20/20 for the right eye and 20/25 for the left eye. Color vision with Ishihara pseudoisochromatic plates was 10/10 for each eye. Pupils were both briskly reactive to light, with no anisocoria and no relative afferent pupillary defect. Intraocular pressures were 14 mm Hg in each eye.

Slit-lamp examination of the anterior segment was normal for both eyes, and confrontation visual fields were full. Amsler grid testing was normal in the right eye, but he noted that all the lines were wavy in the left eye. He had full ductions in each eye, and no evidence of ocular misalignment was found.
