ABSTRACT

Purpose:

To determine the preoperative factors effecting the operation success in patients with concomitant esotropia.

Method:

75 patients with concomitant esotropia operated in Bakirkoy Dr. Sadi Konuk Education and Research Hospital Ophthalmology Clinic between January 2004- December 2007 were included in the study. The strabismus unit records of the patients who were included in the study were surveyed retrospectively. The results were analyzed by using Chi-square test. The surgical success was defined as a squint of 10 Δ or less during far fixation.

Results:

The operative success ratio was 64%. The factors inquired for their effects on the operative success were gender, refractive error, angle of squint, the existence and amount of amblyopia, the existence of anisometropia, the existence and type of fusion, the existence and depth of stereopsis, the age of onset of squint, the age at the time of surgery, the duration and the type of squint. As a result of statistical analyses, while no statistically significant effect of gender, angle of squint, anisometropia, the age of onset of squint and the type of squint on the success of the operation were identified (p>0.05); significant effects of visual acuity, refractive error, the existence of fusion and stereopsis, duration of the squint and the age at the time of surgery were identified (p

Discussion:

We consider that the use of preoperative squint angle as the only criteria in planning the surgery is not enough and determination of new criterias regarding the new studies is required.
