Purpose Endogenous endophthalmitis (EE) is a sight-threatening emergency and the aetiology is often multifactorial. Delayed diagnosis may exacerbate the poor visual prognosis. We describe the management and visual outcomes of EE presenting to a tertiary referral centre. Patients and methods A prospective consecutive case series of 64 patients presenting with presumed EE from 1997 to 2007 to the Royal Victorian Eye and Ear Hospital were included. All data were collected in a standardized manner. Outcome measures included: visual acuity, microbial profiles, and vitrectomy rate. Results In total, 64 cases of EE were identified over the study period with a mean age of 57.5 years, and 53.5% were male. Presenting acuities ranged from Snellen 6/6 to no perception of light (NPL). Identifiable risk factors were present in 78.1%, with the majority related to intravenous drug abuse. A 64.1% culture positivity rate was recorded. A vitrectomy rate of 57, 56, and 21% was recorded in documented bacterial, fungal, and no growth cases, respectively. Final Snellen acuities ranged from 6/6 to NPL. A total of 5 out of 64 eyes were enucleated, of which 3 identified Klebsiella species. Better visual outcome was documented in fungal cases. Conclusion EE is a serious ocular condition and has a varied aetiology. Visual outcomes are often poor, irrespective of the method of management. Fungal aetiology often confers a better prognosis, and vitrectomy is advocated for bacterial proven cases.

Purpose: Bevacizumab (Avastin) is a monoclonal antibody which targets all isoforms of vascular endothelial growth factor A. Its potent anti-angiogenic effects have been shown to cause regression of neovascularization in proliferative diabetic retinopathy. The aim of this study is to investigate the role of Avastin as an adjunct to vitrectomy in the management of severe diabetic eye disease. Methods:Sixteen patients (18 eyes) with severe proliferative diabetic retinopathy were recruited into the study. All eyes underwent a single intravitreal injection of bevacizumab 1.25 mg in 0.05 mL prior to vitrectomy surgery for the management of tractional retinal detachment or vitreous haemorrhage due to severe proliferative diabetic retinopathy.Results: At 3 months, seven eyes had visual acuities which were better than baseline, four were unchanged and seven were worse. At 6 months, 14 eyes had visual acuities better than baseline, one was unchanged and three were worse. Seven of the 18 eyes (38.8%) had postoperative rebleeds, six of which required surgical washout. Conclusion:Avastin improved the ease of the surgery in these complex eyes and the early results are encouraging. We have found it to be particularly useful in diabetic eyes with traction detachments of short duration in which there is still active neovascularization.
