Purpose: To examine the epidemiological characteristics of children undergoing cataract surgery at a referral center in Sao Paulo State, Brazil, as well as the facts surrounding treatment delays.
Methods: In this transversal observational study, 240 operated eyes from 178 children undergoing cataract surgery were reviewed. The following aspects were analyzed: epidemiological and clinical characteristics, parental observations, red reflex test, operated eye, and age at cataract diagnosis and surgery.
Results: The mean ages at the first visit and cataract surgery were 48.9 months (SD=50.0 months) and 64.5 months (SD= 55.4 months), respectively. The most critical sign adverted by parents was leukocoria. The red reflex test was performed on two-thirds of the children, with abnormal results in 28.0%. A family history of cataracts was evident in 30 (20,9%) children (n=144). Previous ocular surgery was found in 37 (16,6%) of the eyes (n=223), anterior segment disorders in 20 (9,0%) eyes (n=221), strabismus in 21 (9,5%) of the eyes (n=220), and nystagmus in 38 (24,4%) of the children (n=156).
Conclusions: One of the causes for the delay in admission may have been the failure to complete the red reflex. In terms of etiology, heredity was the most crucial component. The presence of strabismus and nystagmus in many of these children points to late diagnosis. The most significant impediments to adequate cataract treatment in children were the lack of referral programs and children's specialized ophthalmologic centers, in addition to the restricted number of support professionals trained in the field and pediatric ophthalmology specialists.
