The sequelae of retinopathy of prematurity (ROP) are blindness and visual disabilities. To prevent those problems, photocoagulation and cryotherapy are broadly accepted today. Especially in Japan, photocoagulation treatment was accepted earlier than in other countries. Here we show thirty year outcomes for adults with ROP treated by photocoagulation and/or cryopexy treatments.
Visual acuity (logMAR) was examined. After dilating pupils with tropicamide/phenylephrine, spherical equivalent refraction, axial length, lens thickness, and corneal radii (CR) were measured.
Forty one eyes from 21 patients were followed in this study. The average age was 21.8±4.8 (15-30 years old). Their average visual acuity (logMAR), spherical equivalent refraction, axial length, lens thickness, and CR were 0.03±0.2, -6.0±3.4 diopter, 24.6±1.4 mm, 3.9±0.4 mm, and 7.6±2.3 mm, respectively. Compared to the data from the full-term adults with the same ages, the adult eyes which were treated for ROP have larger lens thickness and smaller CR.
These indicate that higher myopia of the adults treated for ROP is caused by thicker lens and steep cornea, but not by large axial length.
