Monitoring retinoschisis and non‐acute retinal detachment by optical coherence tomography: morphologic aspects and clinical impact

Abstract

Optical coherence tomography (OCT) is a reliable method to differentiate and monitor RS from naRD. Morphological characteristics, including ILB and OLB, could be accurately illustrated in RS.

Paravascular abnormalities observed by spectral domain optical coherence tomography are risk factors for retinoschisis in eyes with high myopia

“…Progression of the splitting and extension of the retinoschisis from the peripheral retina to the macular area has been observed among 4% of patients diagnosed with retinoschisis in a recent prospective study (Eibenberger et al. ). Although vitrectomy combined with ILM peeling technique has improved the anatomical and functional recovery of patients with symptomatic foveoschisis (Lee et al.…”

“…The splitting of the tissue within multiple retinal layers may play a role in transmitting stretching force from the vessels as well as globe expansion. Progression of the splitting and extension of the retinoschisis from the peripheral retina to the macular area has been observed among 4% of patients diagnosed with retinoschisis in a recent prospective study (Eibenberger et al 2017). Although vitrectomy combined with ILM peeling technique has improved the anatomical and functional recovery of patients with symptomatic foveoschisis (Lee et al 2017), follow-up examinations of morphologic features of the PVAs and retinoschisis at vascular arcades may be essential in clinical routine for asymptomatic patients to prevent further visual loss.…”

Optical coherence tomography imaging of the peripheral retina

“…UWF-OCT serves a critical role in distinguishing between retinal detachments and degenerative retinoschisis or schisis detachments, particularly in instances where clinical indicators may be unclear [ Figure 2 ]. [ 5 6 7 ] Clinically diagnosed retinoschisis cases have occasionally demonstrated retinal detachment when observed through OCT, and vice versa. [ 8 9 ] In 2014, Stehouwer et al .…”

“…at the University of Amsterdam’s Academic Medical Centre identified that out of 18 presumptive retinoschisis cases, three displayed retinal detachment upon peripheral OCT examination; another study reported a similar finding in six out of 53 eyes. [ 6 9 ] This differentiation is paramount since the treatment approaches for these two conditions vary considerably. Retinoschisis is often a harmless condition that may not necessitate intervention, but retinal holes, an indication for intervention in retinoschisis, can also be detected on peripheral OCT.[ 10 ] These preliminary studies provide support that UWF-OCT can provide valuable insights for diagnosing and managing retinal detachment in the far periphery.…”

Novel features of degenerative retinoschisis identified using ultra‐widefield multicolor channels: A review of 139 eyes

“…On autofluorescence imaging, retinoschisis usually appears isoautofluorescent, whereas retinal detachments are often hypoautofluorescent (Francone et al, 2020;Huang et al, 2020;Nadelmann et al, 2019;Navaratnam et al, 2021). Peripheral OCT beyond the posterior pole has also proven useful, allowing for diagnostic confirmation and detection of retinal holes or RSRD (Eibenberger et al, 2017;Rachitskaya et al, 2017;Stehouwer et al, 2014;Yeoh et al, 2012). Optos pseudocolour scanning laser ophthalmoscopy, which uses red and green lasers to generate a colour image of the retina, can be reviewed as a combined pseudocolour image or as monochromatic redor green-separated images (Park et al, 2022) This has implications with regards to image interpretation, as different laser wavelengths are able to capture detailed information at different depths of penetration (Park et al, 2022).…”
