ABSTRACT
As a potent collagenase activator,ocriplasmin is a recombinant truncated form of serine protease that retains the protease activity of plasmin.Pre-clinical animal experiments,clinical trials and recent clinical studies all indicated a promising outcome of intravitreal injection of ocriplasmin to treat vitreomacular interface diseases,including vitreomacular adhesion (VMA),vitreomacular traction (VMT) and full-thickness macular hole.Ocriplasmin was approved by the Food and Drug Administration of USA in the management of symptomatic VMA,and by the European Medicines Agency in treating VMT-associated macular hole with less than or equal 400 pm.Further randomized controlled clinical trials are needed for further comprehensive observation and evaluation on its efficiency,safety and other noteworthy issues.
ABSTRACT
ABSTRACT This study aimed to report the clinical and structural outcomes of intravitreal ocriplasmin in the treatment of vitreomacular interface disorders in two tertiary centers in Brazil. A retrospective study was performed by reviewing medical records and spectral domain optical coherence tomography (SD-OCT) findings of seven patients who were treated with a single ocriplasmin injection. A total of 57.14% of patients achieved resolution of vitreomacular traction as evidenced by SD-OCT. Regarding our functional results, 87.71% maintained or improved visual acuity after follow-up. To the best of our knowledge, this is the first study reporting initial results of ocriplasmin therapy in Brazil.
RESUMO O objetivo desse estudo é relatar os resultados iniciais, tanto do ponto de vista funcional quanto anatômico, no tratamento das doenças da interface vítreo-macular com a ocriplasmina em 2 serviços terciários no Brasil. Um estudo retrospectivo foi realizado através de revisão de prontuários, além de análise de achados em tomografia de coerência óptica de domínio espectral (SD-OCT) em 7 pacientes tratados com uma única injeção intravítrea de ocriplasmina. Em nosso estudo 57,14% dos pacientes apresentaram resolução da tração vítreo-macular no SD-OCT. Em relação aos resultados funcionais, 87,71% dos pacientes mantiveram, ou melhoraram sua acuidade visual durante o acompanhamento. Para nosso conhecimento, trata-se do primeiro estudo em nosso país, mostrando resultados iniciais com ocriplasmina em pacientes tratados no Brasil.
