Ocular Changes in Vitiligo Patients on Therapy

April 17, 2022 updated by: Ahmed Abdelshafy, Benha University

Chorioretinal Changes in Vitiligo Patients on Therapy

Vitiligo patients on systemic and local therapy may have some ocular adverse effects associated with the disease and its therapy.

Study Overview

Detailed Description

Chorioretinal changes associated with vitiligo therapy could address patients visual acuity and life style. Early detection of these changes can help these patients to evade such adverse effects.
