Purpose: To describe a multimodal imaging and a 5-year follow-up of a case of cilioretinal artery occlusion (CLRAO) in a 40-year-old woman with idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) syndrome., Methods: Fundus photography, indocyanine green and fluorescein angiography, optical coherence tomography (OCT), OCT angiography (OCTA), and a literature review of retinal artery occlusions associated with IRVAN syndrome were performed., Results: Fundus examination revealed bilateral blurred margins of the discs and peri-vascular hard exudates. Fluorescein angiography (FA) demonstrated peripheral capillary nonperfusion areas in both eyes (OU). It also revealed an aberrant cilioretinal artery in the right eye (OD). OCT showed attenuation of the inner retinal layers and disruption of the outer retinal layers secondary to CLRAO in OD. OCTA allowed a clear identification of macular hypoperfusion in OU. Laser photocoagulation, along with anti-VEGF and corticosteroid intravitreal injections, was administered in OU. Best-corrected visual acuity remained stable, with no evidence of progression or development of neovascularization after a 5-year follow-up., Conclusion: IRVAN syndrome may be complicated by CLRAO, resulting in poor final visual acuity despite reperfusion of the occluded artery. In such cases, multimodal imaging allows the identification of complications such as macular atrophy on OCT and hypoperfusion areas that may not be detected on FA on OCTA., Competing Interests: Declaration of conflicting interests: The authors declared no potential conflicts of interest concerning this article's research, authorship, and publication.

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.

Purpose: To document the intraretinal migration of presumed toxocara larvae mimicking punctate inner choroidopathy, idiopathic choroidal neovascularization, and diffuse unilateral subacute neuroretinitis., Methods: Sequential color photographs, fluorescein angiograms, and optical coherence tomography were performed in three unrelated adult patients with presumed ocular toxocariasis., Results: Characteristic fundoscopic manifestations simulating punctate inner choroidopathy, idiopathic choroidal neovascularization, and diffuse unilateral subacute neuroretinitis were reported in these patients, respectively., Conclusion: Presumed toxocara larvae must be included as a potential cause of different inflammatory diseases as a result of its migration through the retinal layers.
