Article Abstract
Idiopathic retinal vasculitis, aneurysms, and neuroretinitis (IRVAN) is a rare syndrome affecting the retinal and optic disc vasculature. Diffuse retinal ischemia, macular edema, and neovascularization may lead to bilateral vision loss. The authors report a case of a 36-year-old woman presenting with branch retinal artery occlusion (BRAO) in her right eye who was subsequently diagnosed with IRVAN syndrome. She was treated with panretinal photocoagulation for peripheral retinal ischemia and pars plana vitrectomy for vitreous hemorrhage. She later developed a BRAO in her left eye. This case demonstrates that BRAO may be a presenting feature of IRVAN syndrome. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:948-951.].

Neuroretinitis (NR) is characterised by optic disc oedema associated with macular exudates in a star-shaped pattern. Several aetiologies of NR have been described, with cat-scratch disease being the most common. However, despite thorough investigations, one-quarter of cases are classified as idiopathic neuroretinitis (INR), in which visual prognosis is generally good.

Purpose: To report a rare case of bilateral idiopathic multifocal retinal pigment epithelial detachments (imfPEDs) and to describe the long-term morphological and functional changes observed over a 16-year follow-up period.
Methods: A 49-year-old woman was diagnosed with imfPEDs based on multimodal imaging, including optical coherence tomography (OCT), fluorescein angiography (FA), and fundus photography. Full-field electroretinograms (ffERGs) and multifocal ERGs (mfERGs) were recorded to assess retinal function.

Idiopathic macular telangiectasia (MacTel II) is a degenerative disorder of the Müller cells, characterised by pigment proliferation and retinal degeneration. We present a case of an elderly woman with bilateral asymmetric loss of vision. Fundus examination in the right eye revealed profuse pigment proliferation at the macula and pigment plaques temporal to the macula in the left eye, with bilateral retinal greying and right-angled venules.

Purpose: The optimal treatment approach for submacular hemorrhage (SMH) secondary to idiopathic polypoid choroidal vasculopathy (IPCV) remains uncertain. This study aimed to explore the prognosis and complications of pars plana vitrectomy (PPV) followed by subretinal or intravitreal injection with Conbercept (0.05 ml, 10 mg/ml) and tissue plasminogen activator (t-PA) (0.

Growing evidence suggests that Reelin signals and cleavages are affected in neurodegenerative diseases, prospecting a potential role for Reelin in the pathogenesis of neurodegenerative processes occurring in insulted retinas. We sought to determine whether Reelin, Aβ1-42, FTH1 and TAU proteins accumulate in ocular fluids of idiopathic epiretinal membrane (iERM) specimens and whether such accumulations depend on disease severity. Comparisons and correlation studies were used to verify the hypothesis of a Reelin, Aβ1-42, TAU and FTH1 marker expressions in this vitreoretinal disease, extending the knowledge on the pathological spectrum of neurodegenerative eye diseases.
