Table shows the places of retinoschisis in different retinal layers of XLRS patients detected by OCT, the number of affected eyes, the BCVA LogMAR values and the prevalence of different appearance forms. GCL represents ganglion cell layer, INL indicates inner nuclear layer and PRL refers photoreceptor layer. Group A means the presence of cysts in all 3 layers, group B means the presence of cysts in GCL and INL, group C means the presence of cysts in INL only, and group D means the presence of cysts in INL and PRL. Group A and B were the most common appearing forms. The INL was always affected in the cystic stage of the disease. The worst visual acuity was detected when cysts were located in all 3 layers (Group A).
