Outcomes of persistently active neovascular age-related macular degeneration treated with VEGF inhibitors: observational study data


Barthelmes, D; Walton, R; Campain, A E; Simpson, J M; Arnold, J J; McAllister, I L; Guymer, R H; Hunyor, R H; Essex, R W; Morlet, N; Gillies, M C (2015). Outcomes of persistently active neovascular age-related macular degeneration treated with VEGF inhibitors: observational study data. The British Journal of Ophthalmology, 99(3):359-364.

Abstract

AIM: To describe outcomes of eyes with wet age-related macular degeneration (AMD) subdivided by lesion activity in a large multicentre cohort study.
METHODS: Treatment-naive eyes with subfoveal choroidal neovascularisation receiving antivascular endothelial growth factor therapy enrolled in the Fight Retinal Blindness observational study were included. Lesions were graded at each visit as active if there was intraretinal or subretinal fluid attributable to leak from choroidal neovascularisation lesion or fresh haemorrhage. Eyes were divided into four groups; based on the proportion of visits, each eye was graded as active during the first 12 months of treatment (persistent, high, moderate and low activity).
RESULTS: 655 eyes were included. Similar mean visual acuity changes compared with baseline were observed in all four groups at 12 months (+6.8, +8.3, +6.2 and +5.5 letters for the low, moderate, high and persistent groups, respectively; p<0.001 for each group). The mean number of injections given increased only modestly in groups with more active lesions (7.6, 7.9, 8.4 and 8.3, respectively, p=0.015). Occult and minimally classic lesions were more frequent in the more active groups (p=0.024).
CONCLUSIONS: Persistent activity of neovascular lesions during 12 months after starting intravitreal therapy was not associated with worse visual outcomes in this observational study of AMD.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
