Unilateral corneal arcus without carotid artery stenosis.

To the Editor.— A 65-year-old woman with hyperlipidemia (fasting cholesterol level, 315 mg/dl; triglyceride level, 568 mg/dl) was noted to have unilateral corneal arcus of the right eye. Onset of the arcus was unknown. She had no symptoms to suggest amaurosis fugax, cerebral ischemia, or infarction. Her past history included "erysipelas" involving the right eye at the age of 4 years and subsequent recurrences of erythema, pain, and swelling involving the maxillary regions with periorbital swelling of either or both eyes without corneal involvement. This was associated with exacerbations of chronic otitis media. The remainder of her past and family history was noncontributory. Results of the physical examination showed a moderately obese (weight, 76.4 kg; height, 157 cm), mildly hypertensive (blood pressure, 150/95 mm Hg) woman with corneal arcus of the right eye involving the entire circumference of the cornea, separated from the limbus by a lucid zone (Figure).
