Lens correction of infantile myopia in identical twins: a case report.

Spectacles were prescribed for 5-year-old identical twins with similar high, uncorrected, isometropic myopia. One received the full correction, and the other was undercorrected by 4 D. The fully corrected subject was a constant esotrope at distance and near; the undercorrected subject exhibited exotropia at near only. Evaluations over a 5-month period indicated that the full correction was the treatment of choice.
