[Frequency of detection and distribution of narrow pupil in patients with cataracts]

The authors have analyzed 445 patients (464 eyes) living in the Leningrad Region who underwent the removal of age and complicated cataracts (except posttraumatic and diabetic). The pupils width was evaluated against the background of mydriasis with instillations of 1% tropicamid solution. The patients were investigated for the presence of pseudoexfoliative syndrome (PES) and glaucoma. Narrow pupil, PES and glaucoma were observed more often in men than in women (P < 0.05). In patients with isolated PES the narrow pupil was revealed in 32.6%, with isolated glaucoma--in 41.4%, with pseudoexfoliative glaucoma--in 90.9% of the cases. In eyes without PES and glaucoma the narrow pupil was noted in 1.2%. The frequency of detection of narrow pupils increases with age (in patients older than 50 years) and depends on the degree of cataract maturity.
