Clinical Outcomes of Eyes with Submacular Hemorrhage Secondary to Age-related Macular Degeneration Treated with Anti-vascular Endothelial Growth Factor

PURPOSE: To evaluate the long-term outcomes of intravitreal anti-vascular endothelial growth factor (VEGF) monotherapy for patients diagnosed with submacular hemorrhage secondary to exudative age-related macular degeneration. METHODS: This retrospective, observational study included 49 patients (49 eyes) who initially presented with submacular hemorrhage associated with exudative age-related macular degeneration and who were followed-up for at least 24 months. Only eyes that were treated with intravitreal anti-VEGF monotherapy were included in the study. Best-corrected visual acuity (BCVA) measurements obtained at diagnosis, six months, and the final visit were compared. The associations of BCVA at the final visit with baseline BCVA, BCVA at six months, symptom duration, hemorrhage extent, and central foveal thickness were also analyzed. RESULTS: Over the course of follow-up (mean, 32.1 +/- 8.5 months), an average of 5.1 +/- 2.2 anti-VEGF injections were administered. Recurrent hemorrhage was noted in 13 eyes (26.5%). The mean logarithm of the minimal angle of resolution BCVA at diagnosis, six months, and the final visit were 1.40 +/- 0.52, 0.87 +/- 0.64, and 1.03 +/- 0.83, respectively. Both baseline BCVA (p = 0.012) and BCVA at six months (p < 0.001) were significantly associated with BCVA at the final visit. CONCLUSIONS: Improved visual acuity was maintained for more than two years with intravitreal anti-VEGF monotherapy. BCVA at six months is a useful clinical index to predict long-term visual prognosis.

Tratamento da DMRI exsudativa: revisão das drogas antiangiogênicas / Wet-amd treatment: a review in the anti-vegf drugs

Degeneração Macular Relacionada à Idade (DMRI) exsudativa é a principal causa de perda visual severa em indivíduos acima de 50 anos nos países desenvolvidos. O fator de crescimento endotelial (VEGF) é considerado um dos mais importantes reguladores da angiogênese e da permeabilidade vascular . Drogas com atividade antiVEGF tem se mostrado eficaz em preservar ou melhorar a acuidade visual (AV) ao inibir a permeabilidade vascular e o crescimento neovascular nos pacientes tratados. Este artigo de revisão descreve o atual uso terapêutico das medicações antiVEGF para DMRI exsudativa e fornece uma visão geral do futuro da terapia antiangiogênica.

Neovascular age-related macular degeneration is the leading cause of severe, irreversible vision loss in individuals over 50 years in developed countries. Vascular endothelial growth factor (VEGF) has been shown to play a role in the regulation of choroidal neovascularization and vascular permeability. Anti-VEGF drugs have been shown to preserve or improve visual acuity by inhibiting vascular permeability and arresting the growth of neovascularization in the vast majority of treated patients. This review describes the current literature on the use of this therapeutic approach in the management of neovascular AMD and gives an overview of the future directions.
