The introduction of pars plana vitrectomy in clinical ophthalmology by Robert Machemer and colleagues was a profound paradigm change which opened up new avenues for the treatment of ocular diseases, such as proliferative vitreoretinopathy, which up to that time had been incurable [79]. It was again Robert Machemer who together with Yasuo Tano, Gholam Peyman, Stephan Ryan and other researchers f...

Intravitreal triamcinolone acetonide (IVTA) has increasingly been applied as treatment for various intraocular neovascular and oedematous diseases. Comparing the various diseases with respect to effect and side-effects of the treatment, the best response in terms of gain in visual acuity (VA) has been achieved for intraretinal oedematous diseases such as diffuse diabetic macular oedema, branch ...

Purpose: To assess the effectiveness of intravitreal injection of triamcinolone acetonide on macular edema associated with branch retinal vein occlusion (BRVO). Design: A prospective noncomparative interventional case series. Patients & Methods: Fourteen eyes of 14 patients with macular edema associated with BRVO were enrolled. In all patients after thorough ophthalmic examination, 4 mg triamci...

PURPOSE To assess the efficacy of intravitreal use of triamcinolone acetonide combined with laser photocoagulation for the treatment of diffuse diabetic macular edema and to compare it with the separate use of each treatment. METHODS After systemic clinical control, thirty patients with diffuse diabetic macular edema were divided into 3 treatment groups: (1) macular grid photocoagulation; (2)...

OBJECTIVE To evaluate the results of treatment with intravitreal triamcinolone acetonide injection in patients with cystoid macular edema secondary to retinitis pigmentosa. METHODS This prospective, nonrandomized comparative trial included 20 eyes of 20 patients with cystoid macular edema secondary to retinitis pigmentosa (group A) and 20 eyes of 20 control individuals (group B) with the same...

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...
