Medical or surgical orchidectomy: the patients' choice.

cantly different (p<00001). Visual estimation of pupil size is accurate to about 0-2 mm' so detecting anisocoria of 0-5 mm or more presents no clinical difficulty. For practical purposes, therefore, miosis in the affected eye of a patient with unilateral red eye may indicate serious eye disease. We found that when an inflamed eye shows 0 5 mm or more miosis relative to the unaffected eye the probability of serious eye disease is nine times greater than that of mild disease (relative risk, with 95% confidence interval 5 to 18, logit method). Though relative miosis is more common in serious eye disease, a dilated pupil does not necessarily indicate an innocuous condition-for example, acute angle closure glaucoma may present as an inflamed eye with a dilated pupil.
