[Comparison of retinal breaks between patients with atopic dermatitis and mentally retarded patients with...

We compared the distribution of retinal breaks in retinal detachment between patients with atopic dermatitis (AD) and mentally retarded patients who had self-inflicted ocular injury (MR). The cases of AD were 16 eyes in 14 patients (six males and eight females, ranging in age from 15 to 52 years, mean 24.5) and the cases of MR were 6 eyes in 5 patients (5 males, ranging in age from 14 to 25 years, mean 20.2). There was no corneoscleral laceration in either group. In the patients with AD, 14 (87.5%) of 16 eyes had retinal breaks at the vitreous base, and 21 (87.5%) of 24 retinal breaks in 16 eyes were at the vitreous base. In the patients with MR, five (83.3%) of 6 eyes had retinal breaks at the vitreous base and 6(66.7%) of 9 retinal breaks in 6 eyes were at the vitreous base. In both groups, ciliary epithelial breaks and peripheral retinal tears were frequently observed, suggesting that retinal detachment in AD has a pathophysiology similar to traumatic retinal detachment with repeated ocular contusion (self-inflicted injury).
