Visual Outcomes in Delayed Ophthalmic Procedures After Early and Prolonged Childhood Blindness in Adults

Delayed ophthalmic procedures in amblyopic-age children may lead to irreversible visual impairment. The impact of delayed ophthalmic care in adults after early and prolonged childhood blindness has not been well studied. We conducted a review of historical cases to examine visual outcomes in the setting of delayed ophthalmic procedures after early and prolonged childhood blindness due to bilateral visual deprivation. Based on 11 cases which we identified, the best visual acuity which reasonably can be expected after surgery as an adult for severe visual impairment throughout childhood appears to be about 20/200, following a period of visual recovery and rehabilitation, which can take 1 to 1.5 years. These findings underscore the importance of prompt intervention for individuals with visual impairment and better define the best possible outcome when intervention is delayed.
