Vision training for presbyopic nonstrabismic patients.
Home vision training was prescribed for 161 presbyopic patients (ages 45 to 89) who had vision-related symptoms and convergence insufficiency or visual skills deficiencies. Most patients required 10 weeks or less of treatment, the longest treatment period being 15 weeks. Elimination of the symptoms and improved responses on certain optometric tests was achieved by 92% of the patients. Evaluation 3 months after therapy indicated that 77 patients required additional training, the older patients requiring it more often, to retain the initial improvement.
