purpose: to evaluate the efficacy of radial optic neurotomy (ron) combined with or without intravitreal triamcinolone acetonid (ivta) injection in the management of central retinal vein occlusion (crvo). methods: this non-randomized clinical trial was conducted on 23 patients with crvo, who underwent ron with or without ivta injection. preoperative and postoperative best corrected visual acuity...

OBJECTIVE To compare intravitreal triamcinolone acetonide (IVTA) injection versus no treatment or sub-Tenon triamcinolone acetonide (STTA) injection in improving visual acuity (VA) of patients with refractory diabetic macular edema (DME; unresponsive to focal laser therapy). CLINICAL RELEVANCE Diabetic macular edema is the leading cause of visual loss in diabetic retinopathy. Laser therapy ha...

PURPOSE To evaluate the response to intravitreal triamcinolone acetonide for macular edema persisting or recurring despite multiple intravitreal bevacizumab (IVB) treatments for central retinal vein occlusion (CRVO). METHODS Retrospective interventional case series of 21 eyes with CRVO from 21 patients who were diagnosed with persistent or recurrent macular edema secondary to CRVO and treated...

AIM To report an increased incidence of sterile endophthalmitis following intravitreal injection of preserved triamcinolone acetonide (IVTA) from 1 May to 31 July 2006. METHODS Charts were reviewed for all patients who underwent IVTA injections between 1 January 2005 and 31 July 2006 at the offices of a referral vitreo-retinal practice. Patients were included if they presented post-IVTA with ...

purpose: to report treatment with intravitreal triamcinolone acetonide (ivta) in a patient with cystoid macular edema (cme) secondary to retinitis pigmentosa (rp). case report: a 22-year-old male patient with rp presented with progressive visual loss. visual acuity was 9/10 in the right eye and 10/10 in the left eye without refractive error. examination revealed cme in the right eye. after fail...

PURPOSE To report the experiences at our institute of pars plana vitrectomy (PPV) in combination with intravitreal triamcinolone acetonide (IVTA) injection in patients with retained lens material after cataract surgery. METHODS The medical records of patients who underwent PPV between January 2005 and December 2006 after complicated cataract surgery in which lens material was dropped into the...

Intravitreal injection of triamcinolone acetonide (IVTA) has gained widespread use in the treatment of a variety of neovascular and inflammatory intraocular conditions, including proliferative diabetic retinopathy, chronic cystoid macular edema, and chronic uveitis. Intraocular pressure (IOP) greater than 21 mm Hg occurs in approximately 42% of eyes following IVTA. Most of these patients are su...

Background: Cystoid Macular Edema (CME) is one of the most common and sight threatening complications of uveitis. Intravitreal injection of corticosteroids and anti-VEGF antibody are two routine options for treatment. Objective: To compare the effects of intravitreal injections of Bevacizumab and Triamcinolone Acetonide for the treatment of persistent macular edema in non-infectious uveitis. Me...

A 56-year-old man presented with anterior chamber inflammation, increased intraocular pressure, peripheral retinal infiltration, and generalized retinal arterial obstruction suggesting acute retinal necrosis five months after intravitreal triamcinolone acetonide injection (IVTA). He was treated with intravenous antiviral agents and aspirin. Shortly after treatment, retinal infiltrations were re...

AIM To compare therapeutic effects of intravitreal triamcinolone acetonide (IVTA) versus intravitreal bevacizumab (IVB) injections for bilateral diffuse diabetic macular edema (DDME). METHODS Forty eyes of 20 patients with bilateral DDME participated in this study. For each patient, 4 mg/0.1 mL IVTA was injected to one eye and 2.5 mg/0.1 mL IVB was injected to the other eye. The effects of in...
