X-linked juvenile retinoschisis: A case report

X-linked juvenile retinoschisis is a hereditary macular dystrophy that is transmitted in the X-linked recessive mode. Clinical signs include a macular star with or without peripheral retinoschisis responsible for decreased visual acuity. This study dealt with a 12-year-old boy who came in for a consultation for progressive decline in visual acuity. His distance visual acuity without correction was scored at 5/100; the right eye (RE) improved to 10/100 after the correction of a myopic astigmatism; and the unimproved left eye was scored at 20/100. The eye fundus showed perimacular radial lines without increased separation for the right eye with some microcysts and a macular hole on the left. An examination of the retinal periphery of both the eyes found inferotemporal retinal splitting. The electrophysiological assessment showed a major dysfunction on the electroretinogram.Keywords: Degeneration, macula, retinoschisis, sta

Effect Of Trabeculectomy On Ocular Biometry And Refractive Errors In Pediatric Glaucoma

Background: Pediatric glaucoma triggers refractive errors by modifying the biometry of the eye. This study was conducted with the objective of estimating the short-term biometric and refractive changes prior to and post trabeculectomy in pediatric glaucoma. Material and Methods: A 12-month, descriptive, cross-sectional study was carried out from January to December 2019, using patients operated on for pediatric glaucoma. Pre- and post-operative biometric and refraction measurements were noted. Visual acuity, axial length, corneal diameter and refraction were obtained. All ethical requirements (anonymity, free, informed, and continuous consent) were satisfied. Data analysis was done using SPSS 20.0. Results: In the present study, 47 eyes of 27 patients were surgically operated upon, from January 2019 to December 2019 at CHU-IOTA. The predominant sex was male (17 patients) at 63%, giving a sex ratio (M / F) of 1.7. The mean age was 5.04 ± 4.24. Preoperatively, the mean corneal diameter, and D90 were respectively 13.83 ± 1.51 and 12.55 ± 0.99. Preoperatively, the mean axial length, and D90, were 23.87 ± 1.29 and 22.28 ± 1.07, respectively. Preoperatively and at three month, the mean myopia (n = 36), were respectively -3.13 ± 1.83 and -1.59 ± 0.97. The mean preoperative astigmatism (n = 47) and D90 were respectively, -1.59 ± 0.77 and -1.23 ± 0.57. A statistically significant relationship (p <0.05) was found to exist between the preoperative and postoperative data of the axial length, corneal diameter, and refractive errors. Conclusions: Trabeculectomy significantly exerts a short-term positive impact on the biometrics and refraction by modifying the initial measurements and diopters.&nbsp
