Background
Convergence insufficiency is a common binocular vision disorder in which the eyes have a strong tendency to drift outward (exophoria) with difficulty turning the eyes inward when reading or doing close work.
Objectives
To assess the comparative effectiveness and relative ranking of non-surgical interventions for convergence insufficiency through a systematic review and network meta-analysis (NMA).
Search methods
We searched CENTRAL, MEDLINE, Embase, PubMed and three trials registers up to 20 September 2019
Current research suggests that office-based vergence/accommodative therapy with home reinforcement is more effective than home based pencil/target push-ups or home-based computer vergence/accommodative therapy for children. In adults, evidence of the effectiveness of various non-surgical interventions is less clear.
