Background: Intravitreal injection of triamcinolone has been advocated to treat exudative macular diseases such as macular edema and choroidal neovascularization. Objective: To describe 7 patients who developed a clinical picture simulating endophthalmitis after intravitreal triamcinolone injection. Methods: Intravitreal triamcinolone injections were performed to treat refractory cystoid macular edema or diffuse macular edema associated with diabetic retinopathy, macular pucker, branch retinal vein occlusion, or pseudophakia. One patient received an injection in an attempt to treat exudation associated with occult choroidal neovascularization. Results: Preinjection visual acuity ranged from 20/50 to 20/400. An extensive inflammatory response developed 1 to 2 days after injection in all 7 eyes. Five eyes had previously undergone vitrectomy. Four eyes had a layered hypopyon. All 7 eyes had an anterior chamber cellular reaction and vitritis. Visual acuity ranged from 20/400 to hand movements. The first 6 patients were treated for presumed endophthalmitis with vitreous cultures and intravitreal injections of antibiotics. All 6 cultures were negative for any organisms, and the eyes resolved their inflammatory response, with recovery to preinjection visual acuity or better. The seventh patient was treated with topical prednisolone without antibiotic therapy, and the inflammation resolved, with resolution of the macular edema seen before the intravitreal triamcinolone injection. Conclusion: It may be appropriate to closely observe noninfectious, toxic endophthalmitis in patients treated with intravitreal triamcinolone before assuming it to be infectious, especially in the absence of eye pain.

Objective To evaluate the association of subretinal hyper-reflective material (SHRM) with visual acuity (VA), geographic atrophy (GA) and scar in the Comparison of Age related Macular Degeneration Treatments Trials (CATT) Design Prospective cohort study within a randomized clinical trial. Participants The 1185 participants in CATT. Methods Participants were randomly assigned to ranibizumab or bevacizumab treatment monthly or as-needed. Masked readers graded scar and GA on fundus photography and fluorescein angiography images, SHRM on time domain (TD) and spectral domain (SD) optical coherence tomography (OCT) throughout 104 weeks. Measurements of SHRM height and width in the fovea, within the center 1mm2, or outside the center 1mm2 were obtained on SD-OCT images at 56 (n=76) and 104 (n=66) weeks. VA was measured by certified examiners. Main Outcome Measures SHRM presence, location and size, and associations with VA, scar, and GA. Results Among all CATT participants, the percentage with SHRM at enrollment was 77%, decreasing to 68% at 4 weeks after treatment and 54% at 104 weeks. At 104 weeks, scar was present more often in eyes with persistent SHRM than eyes with SHRM that resolved (64% vs. 31%; p<0.0001). Among eyes with detailed evaluation of SHRM at weeks 56 (n=76) and 104 (n=66), mean [SE] VA letter score was 73.5 [2.8], 73.1 [3.4], 65.3 [3.5], and 63.9 [3.7] when SHRM was absent, present outside the central 1mm2, present within the central 1mm2 but not the foveal center, or present at the foveal center (p=0.02). SHRM was present at the foveal center in 43 (30%), within the central 1mm2 in 21 (15%) and outside the central 1mm2 in 19 (13%). When SHRM was present, the median maximum height in microns under the fovea, within the central 1 mm2 including the fovea and anywhere within the scan was 86; 120; and 122, respectively. VA was decreased with greater SHRM height and width (p<0.05). Conclusions SHRM is common in eyes with NVAMD and often persists after anti-VEGF treatment. At 2 years, eyes with scar were more likely to have SHRM than other eyes. Greater SHRM height and width were associated with worse VA. SHRM is an important morphological biomarker in eyes with NVAMD.

Retinal vein occlusion patients treated with multiple DEX implant injections, either alone or combined with other therapies, had improved central retinal thickness and visual acuity with each subsequent injection. No new safety concerns developed with multiple implants.
