Abstract:
We conducted a prospective study of 30 cases which had unilateral congenital blepharoptosis on visual acuity, refractive error, degree of ptosis, levator function, axial length and stereoacuity. A comparison of visual acuity between ptotic and healthy eyes revealed a reduction of visual acuity, but nearly same incidence of myopia in the ptotic eyes. But astigmatism in the ptotic eye was shown higher incidence with a borderline statistic significance(healthy eye 7/30, ptotic eye 14/30, p=0.056). Axial length for ptotic eyes was longer than healthy eye with statistic significance (22.80 +/- 1.46 vs 22.64 +/- 1.40mm, p=0.029). Strabismus was found in 4 cases; of them, 3 exotropia and remaining 1 hypertropia. Stereoacuity was more than 80 seconds except 7 cases which were amblyopic case. We concluded that in case of unilateral congenital ptosis, axial length was longer than healthy eye but incidence of myopia was nearly similar.
