In otherwise healthy patients, the observance of a cotton wool spot (CWS) is not considered normal. A single cotton wool spot in one eye can be the earliest ophthalmoscopic finding in diabetic or hypertensive retinopathy. In a series of patients who had cotton-wool spots and no known medical history, diastolic blood pressure equal to or greater than 90 mmHg was detected in 50% of patients, and an elevated blood sugar was found in 20% of patients.
