Abstract

The authors reported a high incidence of astigmatism and longer axial length in cases of unilateral congenital ptosis. But post-operative changes of refraction and axial length were still obscure. In this reason we analysed on axial length operation. Post-operative refractive errors between ptotic and normal eyes were similar without significant differences(p=0.38). But the incidence of astigmatism in the ptotic eyes was higher(72% vs 32%) and amounts of astigmatism was also increased in the ptotic eye with statistically significant(-1.25 +/-0.49 vs 0.56+/-0.66D, p=0.04). Pre-operative axial lengths for ptotic eyes was longer than those of healthy eyes (22.80+/-1.46 vs 22.64+/-1.40mm, p=0.029) but postoperative axial lengths between ptotic and normal eyes were similar(23.26+/-1.63mm vs 23.28+/-1.60, p=0.87). As results of above, wer concluded that axial lengths of unilateral ptotic eye were similar to those of healthy eye but incidence of astimatism was higher in cases of unilateral congenital ptosis after one year of operation for ptosis.
