Cataract and pseudoexfoliation. A clinicopathological study.

U Krause, A Tarkkanen

    Acta Ophthalmologica
    |June 1, 1978
    PubMed
    Summary

    Histological examination of 100 cataract lenses revealed pseudoexfoliation in 33 cases, often missed in preoperative clinical evaluations. Incidence increased with patient age, and enzyme use did not hinder diagnosis.

    Area of Science:

    • Ophthalmology
    • Pathology

    Background:

    • Pseudoexfoliation syndrome is a common condition affecting the elderly.
    • High incidence areas for pseudoexfoliation exist, necessitating further investigation.
    • Accurate diagnosis is crucial for managing cataract and pseudoexfoliation.

    Purpose of the Study:

    • To histologically determine the incidence of pseudoexfoliation in cataractous lenses from a high-incidence area.
    • To compare histological findings with preoperative clinical diagnoses.
    • To assess the impact of patient age and intraoperative factors on pseudoexfoliation detection.

    Main Methods:

    • Histological examination of 100 cataractous lenses from 98 patients.
    • Patients were from a region with a known high prevalence of pseudoexfoliation.
    • Examiner was blinded to clinical findings; alpha-chymotrypsin use was noted.

    Main Results:

    • Pseudoexfoliation was histologically confirmed in 33 out of 100 lenses (33%).
    • Only 16 cases (48.5% of positive cases) were clinically recorded preoperatively.
    • Pseudoexfoliation incidence appeared to increase with patient age.

    Conclusions:

    • Histological examination reveals a higher prevalence of pseudoexfoliation than clinically diagnosed in cataract patients.
    • Age is a significant factor in the incidence of pseudoexfoliation.
    • Routine pupillary dilatation and enzyme use during surgery do not prevent histological detection.
