This paper sought to review literature on the different classifications and types of nonstrabismic binocular vision anomalies and harmonize these classifications. Search engines, namely Google scholar, Medline, Cinahl and Francis databases, were used to review literature on the classification of accommodative and vergence dysfunctions using keywords like <em>binocular vision dysfunctions</em>, <em>classification of nonstrabismic binocular vision disorders or anomalies</em>, <em>accommodative disorders/anomalies classification</em> and <em>vergence disorders/anomalies classifications</em>, and included works that described these anomalies. Nonstrabismic binocular vision anomalies are classified as accommodative and vergence anomalies. There are three different major types of accommodative anomalies, namely accommodative insufficiency, accommodative infacility (accommodative inertia), and accommodative excess (accommodative spasm), and seven different types of vergence anomalies (convergence insufficiency, convergence excess, divergence insufficiency, divergence excess, basic esophoria, basic exophoria and fusional vergence dysfunctions), which are functional in origin. Functionally, there is a commonly reported interaction between accommodative and convergence insufficiency referred to as pseudoconvergence insufficiency. Accommodative paralysis (subtype of accommodative insufficiency) and vergence anomalies – <em>i.e.</em>, convergence paralysis, convergence spasm and divergence paralysis – are non-functional in origin with underlying systemic disease etiologies. Systemic convergence insufficiency, associated with subnormal accommodation, is a non-functional interaction between the accommodative and convergence insufficiency. The classification of nonstrabismic binocular vision anomalies is based on the description of the clinical signs and the underlying etiology either functional or non-functional in origin. Proper diagnosis and management involves investigation of the underlying etiology in addition to the battery of binocular vision test procedures. 2016-06-17T16:06:59+02:00 ##submission.copyrightStatement## https://www.pagepressjournals.org/index.php/opto/article/view/5566 Symptomatic classic convergence insufficiency treated with dot card orthoptic exercise 2017-04-28T15:06:09+02:00 Charles Darko-Takyi chadarko@yahoo.com Kofi Asiedu kasiedu60@yahoo.com Although lots of studies have been reported on convergence insufficiency (CI), no specific case of CI among African patients has been reported. We report a case of symptomatic <em>classic</em> convergence insufficiency in a female student who previously had been misdiagnosed and managed for refractive error. This case highlights the need for comprehensive binocular vision assessment, administration of validated symptom questionnaires in cases of suspicious CI, and the use of simple and inexpensive vision therapy procedures to manage CI in optometric centres in developing countries. 2016-11-22T09:16:25+01:00 ##submission.copyrightStatement##
