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...

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...

OBJECTIVE Purpose of this study was to validate that Subtenon (SB) Triamcinolone (TA) injection is an alternative to Intravitreal (IV) Triamcinolone (TA) injection for the treatment of diabetic macular edema (DME). METHODS Forty eyes were selected having DME due to type 1 or type 2 diabetes. All the patients were treated with photocoagulation. IVTA was administered in one eye and SBTA in foll...

PURPOSE To assess the effect of intravitreal and posterior subtenon injections of triamcinolone acetonide (TA) on intraocular pressure (IOP). METHODS we reviewed 42 consecutive eyes after intravitreal TA injection (IVTA) and 43 eyes following posterior subtenon TA injection (PSTA). All cases had a minimum follow-up time of three months. After injection, the value and time of the maximal IOP, ...

Comment. Subtenon corticosteroid injections are commonly used in the treatment of macular edema or posterior segment intraocular inflammation. Complications include inadvertent intravascular injection, globe perforation, cataract formation, ocular hypertension, blepharoptosis, orbital fat atrophy, strabismus, or allergic reactions. To our knowledge, this is the first report of an abscess result...

bitis can progress very rapidly— often in a matter of hours—and even with appropriate surgical and antibiotic treatment, it can be fatal or result in serious complications. Escardo et al reported a case of orbital cellulitis caused by F necrophorum that required 3 urgent surgical interventions and 30 days of intravenous antibiotic treatment. Despite this intensive treatment, the patient’s visio...

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...

BACKGROUND To compare the effects of laser photocoagulation combined with subtenon injection of triamcinolone acetonide with photocoagulation alone, for diabetic cystoid macular edema. METHODS This retrospective comparative study analyzed data for 34 eyes with cystoid macular edema treated with photocoagulation alone (n=17) or combined with triamcinolone (n=17). All patients were followed for...
