Abstract
PURPOSE: To assess the influence of scleral reinforcement on the evolution of severe myopia in children. MATERIAL AND METHODS: Scleral reinforcement after Thompson was performed on 251 eyes of 154 children with high myopia from 2 to 18 years of age. The main indication criteria for surgery during the period 1992-2000 included: severe myopia more than -7 Diopters and the increase in refraction more than -1 D(per year. Zenoderm (porcin skin) was the main alloplastic material used during surgery. No serious complications were observed. The following main indicators of myopia advancement were investigated on a long-term basis and evaluated: axial length, refraction, visual acuity, fundus findings and perimetry. RESULTS: The positive influence of surgery on myopia advancement was observed in 100% of patients. In about 53% of operated eyes, myopia was absolutely stopped, and in about 47% of operated eyes, its advancement was considerably reduced. During 10 years of postsurgical check-up, stabilisation of myopia was achieved, the following in individual indicators: axial length--53.8% of eyes, refraction--52.9% of eyes, visual acuity--85% of eyes, fundus findings--58.6% of eyes, perimetry--59.1% of eyes. The advancement of myopia in other 47% of patients has been decreased from 1.1 D/per year before surgery to 0.1 D till 10 years after surgery. CONCLUSION: Scleral reinforcement is an effective and safe surgery that can stabilise the progression of severe myopia in children. (Tab. 6, Fig. 7, Ref. 12.).
