[Study of electrooculogram [EOG] abnormalities in patient with ocular toxoplasmosis]

ABSTRACT

Toxoplasmosis is a parasitic disease caused by Toxoplasma gondii that can affect various parts of the body and it is most prevalent in Asian countries. There are various methods for detection of visual impairment in patients with toxoplasmosis. One of these non-invasive methods is electrooculogram [EOG] which evaluates visual function in patients with toxoplasmosis. This study was performed to determine the prevalence of ocular complications of toxoplasmosis by EOG. In this cross-sectional study, 50 subjects referred to Qods Clinic from 2011 to 2012 including 25 case with ocular toxoplasmosis and 25 control subjects without toxoplasmosis were enrolled and the EOG results were compared among two groups. The mean [ +/- standard deviation] Arden indices were 1.35 +/- 0.25 and 2.3 +/- 0.31 in control and case group, respectively [P=0.0001]. According to our results and comparison with other studies, it may be concluded that ocular complications of toxoplasmosis is more prevalent compared with control group according to EOG technique
