BACKGROUND Refractory pseudophakic cystoid macular edema (PCME) following cataract surgery has long posed a challenge to clinicians, but intravitreal injections with a sustained delivery 0.7 mg dexamethasone implant has emerged as a promising therapy for this condition. OBJECTIVE To present a case of longstanding and refractory PCME with complete remission through 189 days of follow-up after ...

OBJECTIVE Plasma kallikrein (PK) has been identified in vitreous fluid obtained from individuals with diabetic retinopathy and has been implicated in contributing to retinal vascular dysfunction. In this report, we examined the effects of PK on retinal vascular functions and thickness in diabetic rats. RESEARCH DESIGN AND METHODS We investigated the effects of a selective PK inhibitor, ASP-44...

PURPOSE To evaluate the concentration of vascular endothelial growth factor (VEGF) in aqueous humor after a single intravitreal injection of bevacizumab (IVB) in eyes with neovascular age-related macular degeneration (AMD). METHODS In this prospective interventional case series study, 24 eyes of 24 patients with types 1 and 2 choroidal neovascularization secondary to neovascular AMD were trea...

AIM The current study was designed to determine whether intravitreal injection of tacrolimus (FK506) modulates the gene expression of neurotrophic factor-related molecules in the retina from eyes with induced experimental autoimmune uveoretinitis (EAU) in rats. METHODS Rats were immunised with interphotoreceptor retinoid binding protein peptide (R14) and given intravitreal injection of tacrol...

PURPOSE To evaluate bevacizumab toxicity in neurosensorial retina and retinal pigment epithelium in pigmented rabbit eyes by means of histological studies. METHODS Thirty eyes of fifteen rabbits were distributed into three groups: sham group (S), that received a 0.1 ml balanced saline solution (BSS) intravitreal injection (10 eyes); group 1, that received a 1.25 mg (0.1 ml) bevacizumab intrav...

Peripheral exudative hemorrhagic chorioretinopathy (PEHCR) is a rare disorder that sometimes causes sudden subretinal and/or vitreous hemorrhage. Choroidal neovascularization is involved in the pathogenesis, but the etiology is unknown. Treatments with photocoagulation, cryopexy, and intravitreal bevacizumab injection have been reported. However, the therapeutic effect of intravitreal injection...

The efficacy and toxicity of ganciclovir given by intravenous or intravenous plus intravitreal injection were studied in nine patients with cytomegalovirus (CMV) retinitis; seven with AIDS and two with drug induced immunodeficiency. Five patients had retinitis with macular involvement in six sighted eyes; six patients had only peripheral retinitis in seven eyes. In two patients (two eyes) with ...

PURPOSE To identify anomalous features that impact drug delivery in the eye as a result of intravitreal injections using micro-computed tomography imaging. METHODS Three-dimensional micro-computed tomography images were acquired following an intravitreal injection of 0.03 mL of contrast agent into ex vivo porcine eyes (n = 24). A baseline scan was acquired prior to injection to detect any abn...

PURPOSE To report the effect of an intravitreal injection of 1.25 mg (0.05 ml) of bevacizumab (IVB) as symptomatic treatment for neovascular glaucoma. PATIENTS AND METHOD This prospective study included 13 eyes of 12 patients presenting neovascular glaucoma, in two cases secondary to ischemic central retinal vein occlusion and, in ten cases, to proliferative diabetic retinopathy. Each patient...
