My niece is 15 month old. She is suffering from intermittent extropia which comes n goes since she was 10 month. We took. Her to pediatrician eye specialist. The doctor explained she is having squint in both eyes .The vision in her eyes is 20/20. He mentioned the only option is eye muscle surgery at the age of 4. We wanted to know as this the only option for her. We need to evaluate her eye checkup at 6 month interval. What we have observed that nowadays that she is not squinting frequently its like 3 or 4 times a day. Pls suggest some other. Options for her.
