Avastin (bevacizumab) does not exert any toxic effects on the retina and its function, according to a study published in the January issue of Retina journal.

Delaying treatment in patients with subfoveal neovascular age-related macular degeneration (wet AMD) correlates to progressive and substantial loss of visual acuity (VA), according to a report published online ahead of print by Eye.

The OPTTX System (Novadaq Technologies) stabilizes or improves vision at one year in patients with wet age-related macular degeneration (AMD), many of who have failed previous therapies and have no other treatment alternatives, according to Professor Giovanni Staurenghi of Sacco Hospital, University of Milan, Italy, reporting at this year?s EURETINA congress in Vienna, Austria.

V2 Vantage DX, a new generation of retinal imaging software, has been released by Optos plc, UK.

Diabetes-induced changes to 37 separate proteins of the vitreous may be the key to understanding the mechanisms of diabetic retinopathy (DR), according to a study to be published in the June issue of the Journal of Proteome Research.

Clinical doses of Avastin (bevacizumab; Genentech) and Lucentis (ranibizumab; Novartis) are equally effective in neutralizing vascular endothelial growth factor (VEGF), while Macugen (pegaptanib; Pfizer) has no effect, according to a study published online ahead of print by the Journal of Investigative Ophthalmology.

VEGF Trap (Regeneron) maintains a significant improvement in the visual acuity of neovascular age-related macular degeneration (wet AMD) patients up to 32 weeks, according to a study presented at this year's Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO).

Xibrom (bromfenac 0.09 mg ophthalmic solution; ISTA Pharmaceuticals) significantly improves visual acuity outcomes and lowers retreatment rates when administered as an adjuvant to Lucentis (ranibizumab; Novartis) therapy in neovascular age-related macular degeneration (AMD) patients, when compared with Lucentis monotherapy, according to a poster presented at this year's Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO).

All of the excitement surrounding anti-VEGF therapy has been countered slightly by one major issue: the regular treatment and follow-up regimen associated with the new class of treatments.

The authors undertook a study based on their own patient records to elucidate whether Avastin does have a viable role to play in the treatment of neovascular glaucoma associated with retinal ischaemic disease.

At present, there is no effective early-stage treatment for AMD or for arresting its progression in the early phases.

Besides external magnifying glasses, certain intraocular lenses and devices have been proposed as feasible visual aids for AMD patients.

Providing patients with renewed hope and the chance of halting and maybe even reversing vision loss, the launch of this anti-VEGF therapy has signalled a permanent change in the way this debilitating disorder is treated worldwide.

New treatments have not only caused major shifts in practice patterns but have also presented feasible options for pathologies other than those for which they were initially developed.

Second Sight's "bionic eye" implant, the Argus II Retinal Prosthesis System, has been implanted into two blind patients at London's Moorfields Eye Hospital by Dr Lyndon da Cruz and team.

Spectral domain, three-dimensional (3-D), high-resolution optical coherence tomography (OCT) represents a step forward in OCT technology, with precise registration, complete data set acquisition, and improved coverage of the retina being the major advantages.

VEGFb, a novel form of vascular endothelial growth factor (VEGF), an anti-angiogenic which is cytoprotective for retinal cells, can inhibit choroidal neovascularization significantly, according to preclinical results presented at this year's BIO National Venture Conference, held April 22?23 in Cambridge, US.
