Background and design: Alopecia areata (AA) has been accepted as a systemic disease because of its association with some autoimmune diseases and involvement of nail and eye. Ocular alterations have previously been reported in alopecia areata. Indeed, there have been reports of various lens alterations, from cases of cataract to minor punctate opacities. However, there are contrasting opinions as to the prevalence of these lens changes. Involvement of the chorioretina has also been reported in AA, but the significance and etiopathogenesis of both the lens changes and the fundus alterations in patients with AA is obscure. The purpose of this case-control study was to investigate the prevalence and appearance of the lenticular changes occurring in AA. Materials and Methods: One hundred patients (45 women, 55 men; age range 2-70) with AA who were seen at the Dermatology Clinic of Istanbul Medical Faculty were referred for ophthalmological examination including slit-lamp examination as part of the study. One hundred healthy control patients (50 women, 50 men) were also included in this study. Results and Conclusion: There was no statistical difference between the patient and control groups regarding the rates of lenticular alterations. Asymptomatic lens opacity was found in 27 of the 100 patients and 25 of the controls. Cataract was not found either in patient or in control groups. Our data support the hypothesis that lens opacities in patients with AA do not have any significant clinical relevance. So, the opinion of advising ophthalmological examinations in AA patients, emphasized by some authors is not supported.
