PURPOSE Anti-VEGF-A antibody (Ab) (e.g., bevacizumab, ranibizumab) is widely used as a treatment against retinal angiogenesis and edema. The purpose of this study was to evaluate whether intravitreal anti-VEGF Ab injection modulates inflammatory cells in retinal angiogenesis. METHODS To investigate whether intravitreal bevacizumab injections affect the number of inflammatory cells in prolifer...

PURPOSE In an earlier study we found normal adeno-associated viral vector type 2 (AAV2)-mediated GFP expression after intravitreal injection to one eye of normal C57BL/6J mice. However, GFP expression was very poor in the partner eye of the same mouse if this eye received an intravitreal injection of the same vector one month after the initial intravitreal injection. We also found both injectio...

PURPOSE To investigate the ultrastructural changes of the rabbit retina induced by intravitreal methotrexate injection. MATERIALS AND METHODS Ten New Zealand white rabbits were enucleated bilaterally at different time periods after intravitreal methotrexate injection. One rabbit was used as control group and one rabbit was used as intact group. Histopathological examinations were performed un...

AIMS To report the beneficial effect of intravitreal bevacizumab (Avastin) injection in patients with acute central serous chorioretinopathy. METHODS Ten eyes of 10 patients with acute central serous chorioretinopathy received an intravitreal bevacizumab (1.25 mg/0.05 ml) injection. At baseline and follow-up visits patients had best corrected visual acuity (BCVA), IOP assessment, dilated fund...

Aim: To evaluate the effect of intravitreal triamcinolone acetonide on the visual acuity of patients with exudative age related macular degeneration, to assess the duration of a possible effect, and to evaluate clinical side effects of the treatment. Methods: The study included 67 patients (71 eyes) who presented with exudative age related macular degeneration of predominantly or total occult t...

Purpose To describe the efficacy of intravitreal bevacizumab for the treatment of type 1 retinopathy of prematurity (ROP) in zone I. Methods Preterm infants with type 1 ROP in zone I (zone I ROP, any stage with plus disease or zone I ROP, stage 3 without plus disease) were enrolled in this prospective study. Intravitreal bevacizumab (0.625 mg/0.025 ml) was injected under topical anesthesia. P...

PURPOSE This report describes the first recognised case of Rothia dentocariosa endophthalmitis following intravitreal injection. CASE REPORT A 57-year-old indigenous Australian diabetic female developed pain, redness and decreased vision 3 days after intravitreal aflibercept injection to the right eye-administered for diabetic vitreous haemorrhage with suspected macular oedema and proliferati...

AIMS To determine the level of vascular endothelial growth factor (VEGF) and pigment epithelium-derived factor (PEDF) in the plasma of patients with proliferative diabetic retinopathy before and after an intravitreal injection of bevacizumab. METHODS Eleven patients with type 2 diabetes and control of 30 non-diabetic patients were studied. The 11 eyes of 11 patients received an injection of b...

PURPOSE To investigate the efficacy of plasmin and sulfur hexafluoride (SF(6)) on the vitreoretinal junction, as well as the long-term safety in the eye and effect on the recipient's general health after application in the eye. METHODS The study design included four groups of rabbits with three animals in each group. Group 1 received an intravitreal injection (IVI) of plasmin and SF(6) in the...

purpose : to evaluate the toxic retinal effects of intravitreal bevacizumab used for the treatment of exudative age-related macular degeneration (amd) using ganzfeld electroretinography (g-erg) methods : in this prospective comparative interventional study, 23 patients with active choroidal neovascularization (cnv) associated with amd were enrolled. patients were received intravitreal injection...
