Abstract Details

Purpose:

To evaluate the prevalence, clinical characteristics and outcome of strabismus in children undergoing surgery for congenital cataracts

Setting:

Department of Ophthalmology Istanbul Faculty of Medicine Istanbul University, Istanbul, Turkey

Methods:

Clinical records of 138 patients who underwent surgery for congenital cataract between November 1980 and October 2014 were retrospectively reviewed and 69 patients (112 eyes) followed for at least 24 months were included. Demographic characteristics, age at diagnosis, cataract laterality, age at surgery, time between cataract surgery and onset of strabismus, type and degree of stabismus, outcomes were recorded.

Results:

32 (46.4%) were male and 37 (53.6%) were female. 43 patients (62.3%) had bilateral and 26 patients (37.7%) had unilateral congenital cataracts. Mean age at diagnosis of congenital cataract was 11.9+15.3 months and mean age at cataract surgery was 17.4+18.8 months. Mean follow-up was 123.9+71.2 months. IOL implantation was performed in 45 (65%) patients and 24 (35%) were followed as aphakic. Strabismus developed in 23 patients (47.9%) after cataract surgery. 12 (52.1%) had esotropia, 8 (34.8%) exotropia and 3 (13%) had combined deviation. Mean time interval between cataract surgery and strabismus diagnosis was 29.3+29.4 months. Before cataract surgery, strabismus was present in 30% and increased to 62% after surgery. Strabismus surgery was performed in 13 patients.

Conclusions:

Strabismus secondary to congenital cataract was highly prevalent and increased after cataract extraction. Esotropia was more common than exotropia and horizontal and vertical deviations decreased to some extent following strabismus surgery. Children undergoing surgery for congenital cataract should be carefully monitored for the development of strabismus.
