Purpose To evaluate the clinical manifestations and factors affecting onset of strabismus and nystagmus in the congenital cataracts. Methods 148 eyes of the 88 patients who had undergone cataract removal for congenital cataracts between January 1996 year and January 2011 year were reviewed. The age at the surgery was from 6 weeks to 21 years. The factors related with the development of strabismus and nystagmus were analyzed. Results The prevalence rate of strabismus was 28.8% in the bilateral cataracts, and 45% the unilateral cataracts at the last follow‐up. Exotropia was the most common type of strabismus both preoperatively and postoperatively regardless of bilaterality of the cataracts. The same type of strabismus persisted after surgery. Nystagmus was noted in the 18 patients (30.5%) only with bilateral cataracts. Nystagmus was accompanied significantly by strabismus in the 10 patients (55.6%). In the patients with nystagmus, esotropia:exotropia was 4:6 and poor visual prognosis was noted. Strabismus developed more significantly in the patients without primary IOL implantation. Conclusion The factors related with development of strabismus were unilateral cataracts, nystagmus, and aphakic state. Exotropia was the most common type and nystagmus was shown only in the bilateral cataracts.
