Optical Coherence Tomography Evolution in a Case of X-Linked Juvenile Retinoschisis: 15 Years of Follow-Up.

Purpose: We present the evolution of X-linked juvenile retinoschisis (XLRS) in a male patient using optical coherence tomography (OCT) with a long-term follow-up time of 15 years.

Case Description: A 10-year-old male patient presented at the Medical Retina Department of our hospital complaining for blurred vision in both eyes. At the initial presentation in 2001, his best corrected visual acuity (BCVA) was 6/12 in both eyes on the Snellen chart. Based on clinical and OCT findings, the diagnosis of XLRS was made, and it was confirmed by genetic testing. No treatment was performed, but the patient was regularly examined. His BCVA and OCT findings remained relatively stable from 2001 to 2012, when BCVA decreased to 6/18 and 6/24 in the right and left eye, respectively. In 2016, his BCVA was 6/24 and 6/36 in right and left eye, respectively, while OCT depicted significant macular thinning, accompanied by irregularities of the foveal contour in both eyes.

Conclusion: Patients with XLRS should be monitored regularly to evaluate the progression of the disease and manage the potential complications.
