ABSTRACT
ABSTRACT

Purpose:

The present study compared the efficacy of aflibercept for neovascular age-related macular degeneration (NV-AMD) in patients with complete ranibizumab resistance and tachyphylaxis.

Methods:

Forty-four eyes of 38 neovascular age-related macular degeneration patients were evaluated. Eyes were divided into a complete resistance group (n=23 eyes) and tachyphylaxis group (n=21 eyes).

Results:

After three injections, eight (38.1%) patients in the tachyphylaxis group and nine (39.1%) in the complete resistance group presented with macular dryness. After the first injection of aflibercept, the mean visual acuity improved significantly in the tachyphylaxis group (p=0.018) but remained unchanged in the complete resistance group (p=0.37). There was a non-significant trend towards improved mean visual acuity in both groups after the second and third injections relative to the acuity at the final visit for ranibizumab treatment. In the tachyphylaxis group, the presence of subfoveal pigmented epithelium detachment (PED) decreased significantly after intravitreal aflibercept treatment.

Conclusions:

Although treatment with aflibercept yielded generally positive anatomical results in both groups, no significant increase in visual acuity was achieved.
RESUMO
RESUMO

Objetivo:

O presente estudo comparou a eficácia do aflibercept na degeneração macular neovascular relacionada à idade (NV-AMD) com de resistência completa ao ranibizumab e taquifilaxia ao ranibizumab.

Método:

Quarenta e quatro olhos de 38 pacientes com degeneração macular neovascular relacionada à idade foram inscritos. Eles foram divididos em dois grupos grupo de resistência completa (n=23 olhos) e grupo taquifilaxia (n=21 olhos).

Resultados:

Depois de três injeções, 8 (38,1%) olhos no grupo de taquifilaxia e 9 (39,1%) olhos no grupo de resistência completa, apresentaram mácula seca. Após a primeira injeção de aflibercept, a acuidade visual média melhorou significativamente no grupo taquifilaxia (p=0,018) e manteve-se inalterada no grupo de resistência completa (p=0,37). Houve uma tendência de melhora da acuidade visual média em ambos os grupos após a segunda e terceira injeções em comparação com a última visita do tratamento com ranibizumab, mas isso não foi estatisticamente significativo. A presença de descolamento do epitélio pimentado subfoveal (PED) em olhos com taquifilaxia ao ranibizumab diminuiu significativamente após o tratamento aflibercept intravítreo.

Conclusões:

Embora o tratamento com aflibercept tenha mostrado resultados anatômicos positivas em ambos os grupos, não foi obtida melhora significativa da acuidade visual.
