Sensory Evaluation of Cases of Primary Comitant Exotropia

Abstract

This work was designed in order to evaluate the sensory status of pati<:nts having primary comitant exotropia (intermittent and constant exotropia), whom were not subjected to any form of therapy before the time of the tirst examination.

All patients underwent a conventional and complete ocular examination to exclude patients having incomitant strabismus, or sensory exotropia, also patient having vertical incomitance were excluded.

All the patients were subjected to the following:

-History taking

-Cycloplegic refraction

-Best corrected visual acuity

-Measurement of the angle of strabismus at 0.33m and at 6m using the prism and alternate cover test, before and after patching of one eye for 45 minutes -Measurement of the AC/A ratio using the gradient method

-Synoptophore for the detection of stereopsis •.; -Bagolini striated lens, for the assessment of the status of retina I

coiTespondence

-Worth's four- dot test for detection of suppression
