Idiopathic retinal vasculitis, aneurysm, and neuroretinitis (IRVAN) syndrome, pigmented paravenous chorioretinal atrophy (PPCRA) are rare clinical manifestations of unknown etiology. In recent years, with the widespread use multimodal imaging methods in diseases, information about pathogenesis course these diseases has increased. PPCRA is often detected incidentally asymptomatic, whereas IRVAN,...

Giant retinal tear (GRT) is defined as peripheral break extending through 900 or more of the retinal circumference in which the vitreous gel is attached essentially to the anterior flap thereby allowing independent mobility of the posterior edge of tear. GRT needs to be differentiated from Giant dialysis, which is retinal disinsertion from the ora serrata with 90 degrees or more of circumferent...

We describe three cases of shallow posterior rhegmatogenous retinal detachment caused by tiny retinal tears. The clinical appearance of the detachments was very similar to that of idiopathic central serous chorioretinopathy or traction retinal detachment. However, the correct diagnosis was made by finding a tiny paravascular break. Vitrectomy without a thermal adhesion was successful in repairi...

PURPOSE To describe the appearance of inner retinal defects using en face spectral domain optical coherence tomography (SD-OCT) after idiopathic full-thickness macular hole (FTMH) surgery, referred to as concentric macular dark spots (CMDS). METHODS In a retrospective cohort study, the authors evaluated 36 eyes of 36 patients with large idiopathic MH (>400 μm) who underwent standard three-por...

We report a case of bilateral peripheral retinal neovascularization and chronic idiopathic myelofibrosis in a 69-year-old man. Ophthalmic examination revealed peripheral retinal nonperfusion with retinal neovascularization in both eyes and vitreous hemorrhage in the right eye. Fluorescein angiography of both eyes showed a marked midperipheral and peripheral avascular retina temporally with arte...

PURPOSE To evaluate the association between degree of retinal abnormalities and uncorrected visual acuity (UCVA) in idiopathic epiretinal membrane (ERM) patients with a small amount of refractive error. METHODS We retrospectively reviewed 49 eyes (37 patients) of idiopathic ERM patients. We investigated the association between visual acuity and macular status (central macular thickness [CMT],...

AIM To evaluate macular function before and after successful surgical closure of idiopathic macular holes using multifocal electroretinogram (ERG). METHODS 40 patients (40 eyes) with idiopathic macular holes were examined using multifocal ERG both before and after vitreous surgery. The postoperative period was from 1 to 12 months. RESULTS Preoperatively, the electrical retinal response dens...

To assess the potential visual benefit of intravitreal bevacizumab in a patient with macular edema from idiopathic retinal vasculitis, aneurysms, and neuroretinitis, an intravitreal injection of bevacizumab (1.25 mg) was given. Within 1 week, visual acuity improved from 20/60 to 20/30 and optical coherence tomography demonstrated resolution of macular edema. There was no adverse effect. The mac...
