ABSTRACT Purpose: To observe the frequency of occurrence of affections involving the adnexa or the external eye, as well as to describe the demographic profile of patients. Methods: A prospective, population based, randomized study was done in the Midwest region of the state of São Paulo, in the years 2004/2005. Using a Mobile Ophthalmic Unit we evaluated 11,000 people. A comprehensive eye exam was performed. Data were transferred to excel table and for this study we used information relating to annexes and external eye diseases. The frequency of occurrence of the problems detected was statistically analyzed. Results: We identified 1,581(14.4%) disorders in the adnexa or in the external eye. The most common disorders were pterygium (9.4%), hordeolum (0.8%) and changes in eyelid position (1.7%) (ectropion, ptosis and trichiasis).

A total of four schools were selected, two from urban slum in Central Delhi Rouse Avenue and two from a peripheral village on the outskirts of Delhi. All the children studying in the above mentioned schools and residing in the same area were covered. All the study subjects were interviewed, clinically examined and given a proforma to be filled by their parents. Of the total 775 subjects only 91 (11.74%) had ocular infections. Conjunctivitis was the most prevalent infection followed by trachoma, stye, blepharitis and chalazion. The type and prevalence of infection was similar, in both sexes and both areas, rural and urban.
