- Stellate nonhereditary idiopathic foveomacular retinoschisis resolution after vitreomacular adhesion release(2021) NOGUEIRA, T. Machado; COSTA, D. de Souza; ISENBERG, J.; REZENDE, F. A.Purpose: To present a case of stellate nonhereditary idiopathic foveomacular retinoschisis (SNIFR) resolution associated with vitreomacular adherence (VMA) release and propose a potential contributing association between SNIFR and vitreomacular interactions. Observations: A 67-year-old female patient was diagnosed and followed for SNIFR in OD with spectral-domain optical coherence tomography (SD-OCT) scans at presentation and subsequent visits at 3, 6, 16 and 22 months. VMA and foveomacular retinoschisis remained unchanged on SD-OCT during the first 6 months of the follow-up. At 16-month follow-up visit, SD-OCT revealed VMA release and an important improvement of the macular schisis. At 22 months of follow-up, SNIFR cavities completely resolved in the presence of posterior hyaloid separation from the macular area without any adjunct treatment. The authors could not identify any other possible cause to justify the resolution of SNIFR other than VMA release in this case. Patient did not undergo any treatment for OD other than phacoemulsification 3 months after initial visit. Conclusion: The present case illustrates with SD-OCT scans a possible association between SNIFR resolution and VMA release, highlighting a potential tractional component of the posterior vitreous on the internal limiting membrane and consequent glial cells stretching with schisis formation. © 2021
- VITRECTOMY for STELLATE NONHEREDITARY IDIOPATHIC FOVEOMACULAR RETINOSCHISIS ASSOCIATED with OUTER RETINAL LAYER DEFECT(2022) MORAES, B. R. M.; FERREIRA, B. F. A.; NOGUEIRA, T. M.; NAKASHIMA, Y.; JúNIOR, H. P. P.; SOUZA, E. C.Purpose:To describe a case of stellate nonhereditary idiopathic foveomacular retinoschisis associated with outer retinal layer defect treated with pars plana vitrectomy, internal limiting membrane removal, and C3F8 tamponade.Methods:Spectral-domain optical coherence tomography (Heidelberg Engineering, Heidelberg, Germany) scans of a 46-year-old woman with unilateral stellate nonhereditary idiopathic foveomacular retinoschisis were acquired at baseline and 1, 3, 6, and 12 months after surgery.Results:Pars plana vitrectomy was performed after phacoemulsification. The vitreous was circumcised, and the internal limiting membrane was removed with a Tano brush, releasing tangential forces. The patient experienced progressive recovery of the outer retinal layers and improvement of visual acuity during follow-up.Conclusion:Stellate nonhereditary idiopathic foveomacular retinoschisis may be associated with outer retinal layer defect and severe vision loss. Pars plana vitrectomy with internal limiting membrane removal and C3F8 infusion seems to be a safe and feasible treatment in such cases, with potentially good anatomical and functional outcome. © 2022 Lippincott Williams and Wilkins.
