General Binocular Dysfunction (non-strabismic) in a population of Alribat University Students

Abstract

Objective: To determine the presence of general binocular dysfunction (non- Strabismic). In a Population of Alribat University Students. Material and Methods: A cross ectional- based study was conducted in Alribat University Hospital (Ophthalmic clinic), among Alribat University students during the period from June 2017 to January2018.The Main parameters evaluated include patients complain, visual acuity, Refractive Status. Accommodative assessment and orthoptic report. Results: A total of 250 University Students were enrolled in this study; 34% males' and 66% females, the Mean of age was 19.8±1.78 years.31.2 percentage of the subjects had binocular vision dysfunction and 68.8% Of the subjects had normal binocular vision. 11.6% of subjects had convergence Insufficiency, which represents more prevalent condition, 6% had accommodative Insufficiency while distribution of fusional vergence dysfunction 5.2%, Basic Exophoria and Convergence excess were same prevalent representing 3.6% and 1.2% of subjects had divergence excess. Conclusion: binocular vision dysfunction is Prevalent in this population. These Anomalies may cause symptoms of blurred vision, Fatigue, headache, and loss of Concentration. Key words: Binocular Dysfunction, Accommodation, Convergence Insuffiency, Fusional Vergence
