We report the occurrence of macular hemorrhages after one year of use of anti-VEGF intravitreal injections, mainly for subfoveal choroidal neovascularization.
MATERIAL AND METHODS: Four hundred forty five injections were given over one year (from 15 March 2007 to 15 March 2008), for age-related macular degeneration, retinal vascular occlusion, diabetic retinopathy, neovascular glaucoma, and idiopathic macular choroidal neovascularization; distributed as follows: 11.5% Bevacizumab, 18.6% Pegaptanib, 19.3% Triamcinolone, and 50.6% Ranibizumab.
RESULTS: Six macular hemorrhages were observed, resulting in to a sharp decrease in visual acuity (20/400), with loss of five lines. All occurred after one injection of nonselective anti-VEGF (Ranibizumab) on already treated eyes (four previous injections on average, +/- photodynamic therapy). All were secondary to occult choroidal neovascularization or a large pigment epithelial detachment. Three patients presented a pigment epithelial tear.
DISCUSSION: Anti-VEGF intravitreal injections can lead to pigment epithelial tears in case of large pigment epithelial detachment, especially with a small feeder vessel or with large occult choroidal neovascularization. The authors discuss the possible implications of anti-VEGF when macular hematoma occurs: retraction of choroidal neovascularization and alteration of physiological retinal vascularization.
CONCLUSION: Macular hematoma affects visual prognosis in age-related macular degeneration. It may follow intravitreal anti-VEGF injection with large occult neovascularization, especially in previously treated eyes. Injection in large pigment epithelial detachment may cause a risk of epithelial tear. Other studies are necessary to evaluate the role of the nonselective anti-VEGF in the incidence of macular hematoma. | | Language | fre | | Pub Type(s) | English Abstract
