Mitchell Scheimann and colleagues from the Convergence Insufficiency (CI) Treatment Trial Investigator Group (Pennsylvania) presented results from their recent investigation into the management of CI. They compared the effectiveness of practice-based treatments with home-based therapy. Looking at 221 children aged between nine and 17 years, the group monitored CI over a 12-week period and how it responded to each of four different treatments home-based pen-to-nose, the same but with additional computer-based vergence/accommodation exercises, practice based V/A exercises with home reinforcement and a practice-based placebo with home-based reinforcement. Seventy-three per cent of the group using practice-based techniques with home reinforcement showed improvement as compared with only 30 to 40 per cent in the other groups (note a 35 per cent improvement in the placebo group). While this is possibly simply a confirmation of the need for good compliance with instructions, it is also strongly implicatory of the benefit of setting up treatment sessions in the practice under supervision for treating CI.
