Abstract
Limbal-scleral staphylomas in children are a serious problem in pediatric ophthalmology, as they lead to severe consequences, including anatomical death of the eye.The purpose of the work is to evaluate the results of a new combined method for treating limbal-scleral staphylomas in children using and local ultraviolet (UVA) crosslinking of scleral collagen (CSC) and transscleral diode laser cyclophotocoagulation (TDLC).Material and methods. CSC was performed for 2 children aged 12 and 15 with limbal-scleral staphylomas after TDLC. Biomicroscopy, optical coherence tomography of the anterior segment of the eye and determination of the acoustic density of the sclera were used for dynamic observation of patients. The procedure of local UVA crosslinking of limbal staphylomas of the sclera was carried out using a new device for local ultraviolet crosslinking based on the permission of the Ethics Committee of the Helmholtz National Medical Research Center of Eye Diseases. The CSC procedure time was 5 min with an exposure power of 2.5 mW/cm.Results. The use of TDLC and five local CLSC procedures combined with instillations of 0.1% riboflavin solution provided an increase in the thickness and acoustic density of the sclera, as well as a decrease in the area and height of the limbal staphyloma.Conclusion. The first results of treating scleral staphylomas in children using a new device for local UVA crosslinking showed its high therapeutic efficacy and the feasibility of further research to advance this method into clinical practice.
