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 evaluate the effects of posterior subtenon triamcinolone acetonide (ta) injection on clinical, angiographic, and optical coherence tomographic (oct) features in refractory diabetic macular edema (dme). method: in a randomized double-masked placebo-controlled clinical trial, 38 consecutive patients (64 eyes) with dme refractory to previous laser therapy or not suitable for such treat...

BACKGROUND Ubiquitous fungi of the Scedosporium apiospermum species complex (SASC) cause various opportunistic infections. Posterior subtenon triamcinolone acetonide (STTA) injection is a standard therapy for intraocular inflammation and macular edema. We report a case of Scedosporium apiospermum infectious scleritis after a posterior STTA injection. CASE PRESENTATION A 75-year-old man receiv...

purpose : to evaluate the intraocular pressure (iop) rising effect of anterior versus posterior subtenon injection of triamcinolone in eyes with retinal vein occlusion methods : this prospective nonrandomized study was performed on 57 eyes of 57 patients with macular edema due to retinal vein occlusion. 26 eyes received posterior subtenon injection of 40 mg triamcinolone acetonide [pstt] and 31...

Posterior subtenon injections of steroidal drugs are commonly used to treat various chorioretinal inflammatory diseases. Subsequent strabismus is rare, but it is associated with severe visual disturbance when present. We report a case of simultaneous bilateral inferior oblique muscle paresis in a 60-year-old man who developed it after receiving intravitreal injections of bevacizumab and posteri...

PURPOSE To evaluate the effects of posterior subtenon triamcinolone acetonide injection on refractory diabetic macular edema (DME) after intravitreal bevacizumab (IVB) injection failure. METHODS Patients with DME and central subfield thickness (CST) >300 µm who did not respond to IVB injections were retrospectively included. Specifically, we enrolled patients who were diagnosed with refractor...

A 65-year-old male with uncontrolled diabetes, received posterior subtenon triamcinolone (PST) injection in the right eye for diabetic macular edema. Two days following PST, he developed scleral abscess at the injection site. The Gram stain showed Gram positive cocci in clusters. He responded favorably with systemic control of diabetes, topical concentrated cefazolin, concentrated tobramycin, a...

BACKGROUND To investigate the efficacy of posterior subtenon methylprednisolone acetate injection in treatment of refractory diffuse clinically significant diabetic macular edema (CSME). METHODS In a prospective, nonrandomized, interventional case series, 52 eyes were diagnosed with CSME and treated with at least two sessions of laser photocoagulation according to Early Treatment Diabetic Ret...
