Purpose: To analyze the effects of injections of intravitreal triamcinolone acetonide (IVTA) and intravitreal bevacizumab (IVB) on the incidence rates of anterior segment neovascularization (ASN) and neovascular glaucoma (NVG) in patients with macular edema secondary to central retinal vein occlusion (CRVO). Methods: In this prospective, randomized, double-masked, sham-controlled study, 35 pa...

PURPOSE To compare the short-term effects of intravitreal versus posterior subtenon injection of triamcinolone acetonide for diabetic macular edema. METHODS This is a prospective and interventional study. Sixty eyes of 60 patients who had diffuse diabetic macular edema were assigned to receive a single intravitreal injection (4 mg) or a single posterior subtenon injection (40 mg) of triamcino...

PURPOSE To determine the incidence of rebound macular edema after intravitreal bevacizumab in eyes with macular edema secondary to branch retinal vein occlusion and to identify the pretreatment factors that were significantly associated with the rebound. METHODS The changes in the foveal thickness after the intravitreal bevacizumab (1.25 mg/0.05 mL) were studied in 65 eyes of 65 patients with...

Purpose. To report a case of postoperative endophthalmitis caused by Fusarium species successfully treated with intravitreal and systemic voriconazole after treatment failure with amphotericin B. Methods. Clinical case report of a 60-year-old immunocompetent woman who presents with endophthalmitis of unknown origin 4 weeks after uneventful cataract extraction and IOL implantation surgery. IOL e...

PURPOSE To develop and characterize a feline model of retinal degeneration induced by intravitreal injection of adenosine triphosphate (ATP). METHODS Nineteen normally sighted adult cats received 100 μL intravitreal injections of ATP with a final concentration of 11, 22, or 55 mM at the retina. Four animals were euthanized 30 hours after injection and retinal sections examined for apoptosis u...

PURPOSE To report an outbreak of endophthalmitis in three eyes of two patients following intravitreal methotrexate, caused by Ralstonia pickettii. DESIGN Retrospective, noncomparative, consecutive case series. METHODS Medical records and microbiology results of two patients who presented with acute endophthalmitis following intravitreal methotrexate injection in November 2013 were reviewed....

We appreciate the comments by Hui et al. (3) concerning our article (1). We agree about the potential benefits of repeated intravitreal injections of antibiotics. Intravitreal antibiotics have become part of the standard treatment for endophthalmitis. The current antibiotic treatment for acute-onset bacterial endophthalmitis includes vancomycin for gram-positive coverage and either ceftazidime ...

A case of migraine headache triggered by intravitreal injection, and aborted by retrobulbar injection, is reported. To date, migraine and related cephalgia have not been reported after intravitreal injection. Ophthalmologists and neurologists should be aware of this potential sequela of a very common procedure.

We hereby report a case of hemorrhagic macular infarction after intravitreal bevacizumab for chronic multifocal central serous chorioretinopathy (CSC). Issues regarding safety and adverse effects of bevacizumab are discussed. To the best of our knowledge, this is the first reported case of hemorrhagic macular infarction after intravitreal bevacizumab for chronic multifocal CSC.
