NON-SURGICAL CORRECTION OF LONG-STANDING CONCOMITANT STRABISMUS

Authors:

Abstract:

Long-standing concomitant strabismus in childhood is often accompanied by functional complications, including functional suppression scotoma, also known as binocular haploscopic suppression, which interferes with binocular vision restoration and reduces the effectiveness of diploptic treatment. We present the case of a 15-year-old boy with esotropia and functional suppression scotoma. Comprehensive ophthalmological examination included assessment of ocular motility, prism-cover testing, and evaluation of binocular vision using a synoptophore and the special computerized diagnostic and therapeutic program. Initial best-corrected visual acuity was 0.9 in the right eye and 0.8 in the left eye, with esotropia of 30 PD without correction and 15 PD with correction. After a 10-day course of orthoptic therapy, haploscopic binocular vision was restored and the deviation angle decreased. Following diploptic therapy one month later, normal binocular vision with correction was achieved. One year later, orthotropia and stable normal binocular vision were maintained without surgical intervention.
