Optical Scattering from Vitreous Floaters.

Vitreous "floaters" are a common entoptic phenomenon that can result in significant reduction in quality of life in a proportion of sufferers. The authors use a computational mathematical model based on Fourier optics and reflection and transmission coefficients calculated for a planar type II collagen opacity suspended in aqueous to show that floaters are perceived by the patient through interference effects that result in significant variations in intensity on the retina when viewing a constant brightness surface. The model also predicts that backscattered intensity from floaters is ten thousand to one million times lower than the variations in intensity produced on the retina, which demonstrates that the visible effects of floaters for the patient can be highly significant, whereas clinical observation of the vitreous may be entirely unremarkable.

Management of optic disc pit maculopathy: the European VitreoRetinal society optic pit study.

Purpose: To evaluate a variety of techniques, and their anatomical and functional results, for the treatment of optic disc pit maculopathy (ODP-M). A secondary aim was to report on results of secondary procedures in cases of initial failure or recurrence.

Methods: Multicentre retrospective study of 95 eyes with ODP-M, treated by 25 surgeons from 12 countries.

Survey of the use of laser protective eyewear among international retina specialists: a European vitreoretinal society study.

Objective: To report the trends for the use of eye protection methods during retinal laser in clinic and operating room.

Methods And Analysis: Retrospective analysis of a 14-item survey questionnaire submitted to the European Vitreoretinal Society members.

Results: Responses from 630 members were analysed.

VISUAL OUTCOME OF EARLY VITRECTOMY AND INTRAVITREAL ANTIBIOTICS IN ACUTE POSTSURGICAL AND POSTINTRAVITREAL INJECTION ENDOPHTHALMITIS: European Vitreo-Retinal Society Endophthalmitis Study Report Two.

Purpose: To evaluate the visual outcome associated with intravitreal antibiotics (IVA) and pars plana vitrectomy (PPV) for acute postprocedure endophthalmitis.

Methods: Data from 237 eyes presenting with acute postprocedure endophthalmitis were collected from 57 retina specialists in 28 countries. All eyes were treated with IVA on the day of presentation.

Management of vitreous floaters: an international survey the European VitreoRetinal Society Floaters study report.

Background/objectives: To evaluate the efficacy and safety of pars plana vitrectomy for symptomatic floaters.

Subjects/methods: Forty-eight vitreoretinal surgeons from 16 countries provided information on 581 eyes who underwent vitrectomy for floaters in this retrospective survey study conducted by European VitreoRetinal Society. Percentage symptomatic improvement, incidence of retinal tears/detachment and post-vitrectomy cataract surgery, and the factors associated with satisfaction and complications were investigated.

Management of bacterial postoperative endophthalmitis and the role of vitrectomy.

Management of postoperative bacterial endophthalmitis was explored in the Endophthalmitis Vitrectomy Study in 1995, which has underpinned the core protocols in treatment ever since. While surgical techniques have continued to evolve, little has changed in the overall clinical management as no further large randomized controlled trials have taken place. We review the literature addressing the incidence of endophthalmitis, pathogens, antibiotic therapies, and the role of vitrectomy.
