  • Title: Optical coherence tomography in the diagnosis of juvenile X-linked retinoschisis.
    Author: Eriksson U, Larsson E, Holmström G.
    Journal: Acta Ophthalmol Scand; 2004 Apr; 82(2):218-23. PubMed ID: 15043546.
    Abstract:
    PURPOSE: To describe the value of optical coherence tomography (OCT) as a diagnostic tool in the diagnosis of X-linked retinoschisis. METHODS: We report three boys aged between 8 and 17 years, diagnosed with X-linked retinoschisis. During investigations they were examined with OCT (Zeiss Humphrey OCT 1, upgraded version). Single scans of the central posterior pole and the region around the vascular arcades were obtained. Two of the boys underwent full-field ERG according to ISCEV standards. Genetic analysis was performed in all three boys, with sequencing of the XLRS gene. RESULTS: The OCT results revealed a pattern with a cleavage of the retina in two distinct planes, one deep (outer retina) and one superficial. This was very obvious in one patient and a similar but not as pronounced pattern was seen in the other two cases. The two layers were superficially connected with thin-walled, vertical palisades, separated by low reflective, cystoid spaces, confluent and most prominent in the foveal region. CONCLUSION: Full-field ERG and/or DNA analysis are well known methods used for diagnosis of X-linked juvenile retinoschisis. In this paper, we suggest that OCT can also be a helpful diagnostic tool.
