The Effect Of Digital Training System On Convergence Insufficient Asthenopia

Objective:The purpose is to observe the clinical effect of digital training system on convergence insufficient asthenopia.Methods:Eighteen patients with convergence insufficient asthenopia aged18to35years were divided into2groups in a randomized clinical trial, separately treated by digital training system and pen nib training system for12weeks. The author tested the point near convergence and fusional convergence before and after the training, with the data collected from Convergence Insufficiency Symptom Survey (CISS). Treatment effects were compared at last.Results:The author found that after treated, both groups’near convergence points became nearer and fusional convergence increases significantly. The results of digital training system were better than those of pen nib training system. Asthenopia was significantly reduced in digital training system but not in pen nib training system.Conclusions:No matter in subjective assessment or convergence function test, digital training system was better than pen nib training system in treating convergence insufficient asthenopia.
