Impaired Capillary Perfusion in Deep Retinal Layer and in Choriocapillaris in Foveomacular Retinoschisis (OCT, Triton-OCTA, Colour Photography Posterior Pole)

Retina -> Enfermedades Maculares Adquiridas
Patient: 63 years of age, female, BCVA 0,63 at OD, 0.8 at OS, IOP 15/17 mmHg. Ocular Medical History: blur at OD. General Medical History: arterial hypertension. Main Complaint: asthenopia symptoms. Purpose: to explore the structural features of retinoschisis using optical coherence tomography angiography (OCT-A), and to evaluate the characteristics of the perfusion of inner/outer retina, and choriocapillaris. Methods: Colour Photography Posterior Pole, Triton OCT, Triton OCT-Angiography Findings: Colour Photography Posterior Pole: radial spoking around the fovea. Triton OCT: revealing schisis predominantly in the outer plexiform layer (OPL) in the foveal region. Triton OCT-Angiography, Deep Retinal Layer: impaired capillary perfusion in deep retinal layer, increased area of foveolar avascular zone. Triton OCT-Angiography, Choriocapillaris: impaired capillary perfusion in choriocapillaris with focal drop outs. Triton OCT-Angiography, Superficial Retinal Layer: mainly regular capillary perfusion in superficial retinal layer, regular foveolar avascular zone. Discussion: Padrón-Pérez et al. (1) explored the structural features of juvenile X-linked retinoschisis (XLRS) using swept-source-optical coherence tomography and optical coherence tomography angiography (OCT-A). He found that BCVA was significantly correlated with defects in outer plexiform layer, external limiting membrane, and ellipsoid portion of inner segment. Literature: 1.
