Bilateral deprivation amblyopia.
Two children had toxic bilateral cataracts at the ages of 36 months and 41 months and were deprived of treatment for the next 15 and eight years, respectively. After successful surgery the visual results were about 20/40 in both eyes. This visual recovery suggests that the susceptibility to bilateral stimulus deprivation at this age is slight but not absent, and furthermore that the longtime deprivation beyond the sensitive period does not effect greatly the ultimate outcome of the treatment. Absence of nystagmus supports the opinion that the visual motor system is mature by the age of 3 years.
