PURPOSE to report a case of severe ocular hypertension occurring as a complication after a single intravitreal injection of triamcinolone acetonide for the treatment of a diabetic cystoid macular edema. METHODS interventional case report. RESULTS a 63-year-old pseudophakic diabetic woman developed a severe and relatively sudden IOP increase to 50 mm Hg one month after receiving a single 4-m...

PURPOSE To evaluate the changes in intraocular pressure (IOP) after intravitreal injection of triamcinolone acetonide for the management of diabetic macular edema (DME). METHODS The study design is a prospective, interventional, two-arm, dose-response study. Nineteen patients with bilateral DME were included, one eye for every patient underwent intravitreal injection of 4 mg triamcinolone ace...

PURPOSE To determine whether moxifloxacin can be used safely as an intraocular antibiotic, retinal safety of intravitreal moxifloxacin was studied with electroretinography (ERG) and histopathology in animal models. METHODS Moxifloxacin was injected into mouse eyes at intravitreal concentrations of 5 to 500 microg/mL and into rabbit eyes at 150 microg/mL. As the control, the vehicle was inject...

BACKGROUND/AIMS To evaluate intravitreal aflibercept versus laser in subgroups of patients with baseline Diabetic Retinopathy Severity Scale (DRSS) scores ≤43, 47, and ≥53 in VIVID-DME and VISTA-DME. METHODS Patients with diabetic macular oedema were randomised to receive intravitreal aflibercept 2 mg every 4 weeks (2q4), intravitreal aflibercept 2 mg every 8 weeks after five initial monthly ...

Purpose. To measure the chemotherapeutic effects of focal melphalan (intravitreal and subconjunctival) on tumor burden, hypoxia, and vasculature in LHBETATAG murine retinoblastoma model. Methods. LHBETATAG transgenic mice were treated with a single 1 mcg intravitreal injection of melphalan, 100 mcg subconjunctival injection, or semiweekly 10 mcg subconjunctival injections for 3 weeks. At 1 or 3...

In order to prevent central nervous system (CNS) involvement and improve the prognosis of primary intraocular lymphoma (PIOL), we prospectively evaluated the efficacy of combined therapy using intravitreal methotrexate (MTX) and systemic high-dose MTX on treatment-naïve PIOL. Patients with newly diagnosed PIOL whose lymphoma was limited to the eyes were enrolled. The patients were treated with ...

BACKGROUND Cytomegalovirus (CMV) retinitis is the most common opportunistic ocular infection in AIDS patients, and frequently leads to blindness if untreated. Intravitreal ganciclovir proved to be effective in stopping the progression of the disease. OBJECTIVES To determine the efficacy and complications of intravitreal ganciclovir (2 mg in 0.1 ml per injection) to control CMV retinitis. ST...

Polypoidal choroidal vasculopathy is a relatively common type of degenerative macular disease among the Chinese population. This study aims to describe the therapeutic responses to combination therapy with photodynamic therapy, intravitreal aflibercept and intravitreal dexamethasone in patients with polypoidal choroidal vasculopathy. A prospective series of 17 eyes of 13 patients suffering from...

We report the case of a patient with an aggressive retinal astrocytoma accompanied with macular edema and neovascular vessels, who was initially treated with intravitreal bevacizumab injections. A 24-year-old male presented to our clinic complaining of visual disturbance in his right eye. At 8 years of age, he had been diagnosed as having tuberous sclerosis complex. Fundus examination demonstra...

Intraocular injection has become an increasingly important intervention in the treatment of posterior segment diseases. However, an acute intraocular pressure (IOP) elevation after intravitreal injection is a common concern. This study aimed to evaluate the efficacy of intravitreal infusion in maintaining stable IOP in a rabbit model. Trypan blue (TB) 0.06% with an external pump was used to eva...
