RESUMEN
PURPOSE: To review the clinical features, microbiology spectrum, management, and outcomes of patients with endogenous endophthalmitis in Western Australia over a 16-year period. METHODS: This is a retrospective chart review of all patients with endogenous endophthalmitis who presented to all tertiary ophthalmology departments between 2000 and 2015 in Western Australia. RESULTS: Sixty-six eyes of 57 patients with endogenous endophthalmitis were identified, and follow-up data were available for a mean of 554 days. The average frequency was 1.6 per 1,000,000 population per year. Diabetes mellitus (33%) and intravenous drug use (30%) were the most common risk factors. Concurrent systemic infections included urinary tract infection (28%), pneumonia (23%), and endocarditis (21%). Among culture-positive cases (93%), 57% were bacterial and 43% were fungal. Visual acuity improved in 33 (50%) and declined in 15 eyes (22.7%). Baseline visual acuity and the presence of Gram-negative or filamentous fungi were the only predictors of final visual acuity (P = 0.023 and P = 0.001). CONCLUSION: The population frequency of endogenous endophthalmitis has not changed over 16 years despite the changing profile of pathogen and risk factors. Similar to previous studies in Asian and Western countries, visual and anatomical prognosis depends on initial visual acuity and isolated pathogen. Gram-negative and filamentous fungi culture predicted a worse visual outcome.

PURPOSE: The Spectralis Heidelberg retina angiography + optical coherence tomography (OCT) device often fails to acquire near-infrared autofluorescence (NI-AF) due to poor signal because of interference by the beam splitter used for aligning the laser source with the OCT diode light source. We report the rates of successful NI-AF image acquisition using indocyanine green angiography (ICGA) mode (without dye) compared with combined fluorescein angiography (FA) + ICGA mode (without dye) in patients with geographic atrophy (GA). DESIGN: This was a retrospective review. METHODS: Two hundred images from 50 eyes of 25 patients with GA were included. All patients underwent NI-AF imaging using ICGA (787 nm) and combined FA + ICGA (488 + 787 nm) modes in both eyes. Each eye had macula- and disc-centered imaging. The rates of successful image acquisition were compared using McNemar test. RESULTS: Successful NI-AF acquisition using ICGA was 48% to 52% in macula-centered views and 36% to 56% in disc-centered views. Only 36% of patients had successful bilateral NI-AF imaging. This improved to 100% in all views in both eyes after switching to combined FA + ICGA mode (P < 0.001). Logistic regression showed no patient or ocular factors were predictive of NI-AF acquisition failure in ICGA mode. CONCLUSIONS: Acquisition of NI-AF images in GA using ICGA mode has a high failure rate, which can be eliminated by using combined FA + ICGA mode. This finding has implications on the design of imaging protocols for routine assessment and clinical trials of geographic atrophy.
