Strabismus surgery may improve outcomes in adults with comitant non-accommodative esotropia: Study

A recent retrospective study found the clinical characteristics and surgical outcomes of adults suffering from comitant non-accommodative esotropia. This condition is characterized by inward deviation of the eyes, affects many adults and often leads to significant visual disturbances such as diplopia (double vision).

The study spanned nearly a decade from 2014 to 2023 and meticulously reviewed the medical records of 219 patients aged between 18 and 60 years who underwent strabismus surgery. The patient cohort predominantly consisted of women who accounted for 64% of the cases, with an average age of 36.7 years. 72% of the patients were myopic which indicated a high prevalence of nearsightedness among the patients affected by this condition.

This study categorized esotropia into three distinct groups based on the disparity between near and distance angles of deviation as, basic esotropia (ETBA), esotropia divergence insufficiency pattern (ETDI) and esotropia convergence excess pattern (ETCE). This classification helped to better understand the varying presentations of the condition and tailor surgical interventions accordingly.

The key findings from the study revealed that patients in the ETCE group expressed the largest mean deviations with 45.5 prism diopters (PD) at distance and 64 PD at near. Also, the ETBA group demonstrated the greatest range in deviations with 31 PD at distance and 30 PD at near which highlighted the variability in esotropic presentations.
