Prognostic indicators in ocular hypertension.

Decreased pupil size and lens opacity, rather than high intraocular pressure, have been cited as reasons for the concentric constriction of the visual field occurring in eyes with suspected glaucoma. We studied a group of eyes showing ocular hypertension and found increased concentric constriction of the visual field when compared with that of healthy control eyes. While the degree of constriction and patient age tended to predict the transition to glaucoma, we found the absence of hypermetropia to be a strong prognostic indicator.
