RESUMO
PURPOSE: To report the causes of childhood-onset uveitis in a tertiary pediatric ophthalmology hospital in Egypt. METHODS: Retrospective study of the medical records of all uveitis patients following up at a tertiary pediatric ophthalmology hospital in Egypt from January 2017 to December 2020. RESULTS: The present study included 388 patients. The most common anatomical category was intermediate uveitis (30.4%), and around half of these children had pars planitis. This was followed by panuveitis (25.5%), posterior uveitis (23.5%), and anterior uveitis (20.6%), in decreasing frequency. Juvenile idiopathic arthritis, toxoplasmosis, and Vogt-Koyanagi-Harada syndrome were the most common causes of anterior uveitis, posterior uveitis, and panuveitis respectively. Cataract (40.5%), glaucoma (33.8%), and cystoid macular edema (31.6%) were the most frequent ocular complications. CONCLUSION: The present report provides the relative prevalence of the different anatomical types of uveitis, as well as their main causes in a cohort of Egyptian patients with childhood-onset uveitis.

PURPOSE: To assess the clinical outcomes after sequential surgical implantation of intracorneal ring segments and transepithelial corneal collagen cross-linking (TE-CXL) in keratoconic eyes. METHODS: In this consecutive randomized study, 40 eyes of 29 patients with progressive mild to moderate keratoconus were included and were randomly divided into two groups. Group 1 included 20 eyes that underwent Keraring implantation, and group 2 included 20 eyes that underwent Keraring insertion followed by TE-CXL 1 month later. In both groups, channel creation was performed manually. Visual, refractive, and topographic outcomes were measured preoperatively and 1, 3, and 6 months postoperatively. RESULTS: There was statistically significant improvement in both groups regarding uncorrected distance visual acuity (P < 0.001) and corrected distance visual acuity (P < 0.001), with a significant reduction in the refractive error and keratometric values (P < 0.001). There was no statistically significant difference between both groups regarding changes in uncorrected distance visual acuity, corrected distance visual acuity, and refractive error (P > 0.05). However, group 2 revealed a more statistically significant reduction in spherical refraction after 3 months (P = 0.04) and highly significant improvement after 6 months (P = 0.004). CONCLUSIONS: Intracorneal ring segment implantation is an effective procedure for visual and refractive improvement in keratoconic eyes. The addition of TE-CXL to the procedure compensates for residual superficial irregularities, disrupts the progression of the disease, and provides greater improvements in spherical values. The process is simply a deep stretch with superficial lamellar stiffness.
