Systemic vasculitides can cause retinal vascular pathology, including cotton-wool spots, retinal hemorrhages, vascular occlusion, and capillary nonperfusion. Two main causes of visual decline include macular edema and retinal neovascularization. Presumably, both of these complications are caused by increased intraocular levels of vascular growth and permeability factors. We report a patient with occlusive retinal vasculitis associated with mixed connective tissue disease who was treated with intravitreal bevacizumab for chronic macular edema. One month after treatment, visual acuity improved from 20/80 to 20/60, and foveal thickness decreased from 543 microns to 306 microns. This effect persisted for at least 3 months after treatment. No complications, including increased retinal ischemia, were observed.

Background: Pseudophakic cystoid macular edema (CME) following primary anterior-chamber intraocular lens (ACIOL) implantations is commonly seen. Intravitreal triamcinolone acetonide (IVTA) injections have shown significant improvement in visual acuity and retinal thickness in refractory pseudophakic CME. Pseudohypopyon following IVTA injection is a known entity.

Introduction: Diabetic macular oedema (DMO), a serious ocular complication of diabetic retinopathy (DR), is a leading cause of vision impairment worldwide. If left untreated or inadequately treated, DMO can lead to irreversible vision loss and blindness. Intravitreal injections using antivascular endothelial growth factor (anti-VEGF) and laser are the current standard of treatment for DMO.

Juvenile dermatomyositis with emphasized vasculopathy is rare, but the most severe form of the disease, with a poor prognosis with relapsing and chronic course or, in some cases, lethal outcome. We present a case of a 19-year-old Caucasian female, who developed severe acute juvenile dermatomyositis with emphasized multisystem vasculopathy, including retinal vasculopathy and maculopathy (cotton-wool spots, retinal hemorrhages, macular edema) at the age of 8. Due to no response to standard treatment protocols and rapid worsening of clinical symptoms and laboratory findings, a TNF inhibitor (infliximab) was introduced after the third week of treatment resulting in complete normalisation of muscle enzyme levels and complete resolution of eye changes within the next 2 weeks with a gradual general recovery.

Methods: Spectral-domain optical coherence tomography (SD-OCT) scans were conducted on 22 DME patients and 20 RVO patients. Ordinary least squares (OLS) regression was employed to analyze the association between VA and the presence of the foveal bulge, as well as factors such as sex, age, central foveal thickness, various line scans of the fovea, and the external limiting membrane (ELM).
