Clinical features at presentation of anterior segment pigment dispersion syndrome.
One hundred and twenty patients with anterior segment pigment dispersion syndrome were reviewed in order to ascertain the features of the condition and form some idea of their significance. Patients were regarded as having pigment dispersion syndrome on the basis of heavy trabecular mesh pigmentation with at least one other feature of the condition. Although common in men, 44 patients, or a little over one-third, were women. Average age at presentation was 47.8 years with women presenting 10 years later than men. Intraocular pressure was very variable at presentation being less than 20 mmHg in 23 patients. Some patients with elevated pressure had no field loss. Variable myopia was recorded in 38 patients: 30 patients were not myopic. Anterior chamber depth was also variable, the average being 3.0 mm, but six patients had a depth of 2.2 mm or less. The syndrome is extremely variable in its features at presentation. The mild hypoplasia and the hypoperfusion of the iris previously described is consistent with the laxity of the iris noted by Ritch and colleagues.
