Accommodative dysfunction

Abstract

A retrospective review of the records of 114 subjects with accommodative dysfunction has been completed. Most subjects (N = 96) were found to have accommodative insufficiency. Lesser numbers of subjects were categorized in the class of infacility of accommodation (N = 14), spasm of accommodation (N = 3) and fatigue of accommodation (N = 1). A majority of the subjects presented with complaints of blur, headaches and/or asthenopia while attempting nearwork. Most subjects presented with reduced abilities in one or more of the following areas: accommodative amplitude and facility, fusional vergences, near point of convergence and stereo acuities. The clinical characteristics of the group as a whole and the major subgroups have been examined both before and after treatment of the condition with orthoptic exercises and/or plus lenses at the nearpoint. The result of the treatment indicates that although most subjects (96%) experienced some relief with treatment only about half (53%) had their problems totally solved. The importance of these findings is briefly discussed.

Evaluating Relative Accommodations in General Binocular Dysfunctions

“…Traditionally, their importance has been less than other binocular tests, and some authors have not included them when assessing the diagnosis of general binocular anomalies. [2][3][4][5][6] Depending on the authors, [7][8][9][10][11] the anomalous values of relative accommodations can be associated with particular dysfunctions. Thus, a low value of NRA may be encountered in convergence insufficiency and with accommodative excess, whereas a reduced PRA is associated with accommodative insufficiency and with convergence excess.…”

“…Due to the interactions between accommodation and vergence, the values of fusional vergences and relative accommodations are so related that one would think that it is not necessary to study them together in a visual analysis. In fact, some authors [2][3][4][5][6] do not use relative accommodations for diagnosing general binocular disorders, more because of a question of duplicity than for not being a valid test. However, other authors use relative accommodations as a reference in the diagnosis of accommodative and vergence dysfunctions [7][8][9][10][11] or as tests associated with the visual function.…”

Near Reflex Spasm

“…Olguların yaklaşık %3' ünde akomodatif bozukluklara serebellar tümörler, kafa içi basınç artışı, pineal kist veya kafa travmaları gibi nörolojik hastalıklar eşlik eder. 10 London ve ark.…”

Uveitis Induced Cyclospasm Induced Myopia-A Unique Case

“…With AS, hyperopes may appear less hyperopic, emmetropes may appear myopic, and myopes may appear more myopic [2,3]. AS is rare and occurs in less than 3% of patients with accommodative disorders [4]. Even though uveitis is known to produce ciliary muscle spasm, there has not been any case in literature of uveitis induced AS with induced myopia as a presenting symptom.…”
