Preoperative Predictors for Esodeviation and Exodeviation after Cataract Surgery in Children.

Purpose: For those children that went on to have strabismus surgery after cataract surgery, we sought to identify preoperative predictors for whether strabismus surgery would be for an esodeviation or for an exodeviation.

Design

Retrospective studyMethods: Charts of patients <18 years who underwent cataract surgery were reviewed. Data from the first strabismus surgery after cataract surgery were reviewed. Statistical analysis was performed using T-test for continuous variable and chi-square test for categorical variable. A binomial logistic regression was performed to ascertain the effects of variables that were found to be significant.

Results

142 patients were identified having strabismus surgery. Type of deviation at first strabismus surgery was: Esodeviation: 72 (50.7%), exodeviation 55 (38.7%), and surgery for only vertical strabismus 15 (10.6%). Age at cataract surgery was an independent variable determining subsequent surgery for esodeviation or exodeviation. For each year increase in age at cataract surgery, the odds of having surgery for exotropia instead of esotropia increases by a factor of 1.620 (P = .005). Odds that strabismus surgery will be for exodeviation is 4.9 times higher in children who had cataract surgery at 1 year of age or greater as compared to children <1 year of age (P < .001).

Conclusion

For those children who went on to have strabismus surgery after cataract surgery, younger age at cataract surgery increases the chance that subsequent strabismus surgery will be for an esodeviation. Those who had cataract surgery at an older age were more likely to have surgery for exotropia than for esotropia.
