BACKGROUND To compare the efficacy of intravitreal conbercept and ranibizumab in the treatment of diabetic macular edema (DME) in a real-life clinical practice. METHODS This was a retrospective study. Among 62 Chinese patients with DME, 32 patients (36 eyes) received intravitreal conbercept (IVC) injections and 30 patients (32 eyes) received intravitreal ranibizumab (IVR) injections, once a m...

OBJECTIVE To investigate whether intravitreal corticosteroid therapy reduces the extent of inflammatory intraocular tissue damage caused by Bacillus cereus endophthalmitis. METHODS New Zealand white rabbits were inoculated with 1 x 10(6) B cereus organisms and randomized to receive no treatment (control eyes; n=14), intravitreal vancomycin hydrochloride (n=13), or a combination of intravitrea...

OBJECTIVE To elucidate the mechanism of the unique beneficial effect of intravitreal steroid therapy on diabetic macular edema, we investigated the effect of locally administered triamcinolone acetonide (TA) on the expression of vascular endothelial growth factor (VEGF)-A and its receptors in retinas of rats with streptozotocin (STZ)-induced diabetes. We then correlated the expression of these ...

AIMS To evaluate the effect of trans scleral cyclophotocoagulation (TSCPC) on intraocular pressure (IOP) in the eyes retaining intravitreal silicone oil with medically uncontrolled secondary glaucoma following intravitreal silicone oil injection. METHODS Medical records of 11 eyes of 11 patients who underwent TSCPC for medically uncontrolled glaucoma without pupillary block following intravit...

Introduction: Submacular hemorrhage (SMH) is a leading cause of severe visual loss. Pneumatic displacement of SMH from the macular area using intravitreal injection of tissue plasminogen activator (tPA) and gas and vitrectomy with subretinal injection of tPA and intravitreal injection of gas have recently been used as the standard therapies for SMH patients. However, little has been reported on...

PURPOSE To investigate the short-term effects of panretinal photocoagulation (PRP) combined with an intravitreal injection of Avastin(bevacizumab) as an adjuvant to high-risk proliferative diabetic retinopathy (PDR). METHODS The data was collected retrospectively from the eyes of high-risk PDR patients, which were divided into two groups. One eye was treated with only PRP (PRP only group) and...

BACKGROUND Intravitreal injection of triamcinolone has been advocated to treat exudative macular diseases such as macular edema and choroidal neovascularization. OBJECTIVE To describe 7 patients who developed a clinical picture simulating endophthalmitis after intravitreal triamcinolone injection. METHODS Intravitreal triamcinolone injections were performed to treat refractory cystoid macul...

PURPOSE To compare the pharmacokinetics and retinal toxicity of various doses of intravitreal triamcinolone acetonide (TA) in rabbits. METHODS The rabbits received intravitreal injections of 4 mg and 8 mg TA. The drug concentrations were determined with high-performance liquid chromatography after extraction from the vitreous at various time points. The main pharmacokinetics parameters were c...

AIM To evaluate the association between the size of peripheral retinal non-perfusion and the number of intravitreal ranibizumab injections in patients with treatment-naive branch retinal vein occlusion (BRVO) and macular edema. METHODS A total of 53 patients with treatment-naive BRVO and macular edema were included. Each patient underwent a full ophthalmologic examination including optical co...
