چکیده

Purpose To assess the effect of ocriplasmin on visual function response (VFR) measured using visual acuity (VA) and vision-related quality of life, and to quantify the association between release of vitreomacular adhesion (VMA) at day 28 and VFR. Methods Prespecified analysis of secondary endpoints from a randomized controlled trial. Of 220 participants with symptomatic VMA/vitreomacular traction (VMT), including VMT associated with a macular hole up to 400 μm, 146 received a single intravitreal injection of 125 μg ocriplasmin and 74 a sham injection. Based on principal components analysis results, a VFR was defined as either a VA improvement of ≥2 lines or an improvement exceeding the minimal clinically important difference (MCID) in the composite or the mental health subscale scores of the Visual Function Questionnaire (VFQ-25). The MCID was estimated using the standard error of measurement approach. The main outcome measure was the VFR at month 6, with further assessments at months 12 and 24. Results The MCID was estimated at 3.71 points for the VFQ-25 composite score and 10.71 for the VFQ-25 mental health subscale score. A VFR occurred in 51.0% of ocriplasmin versus 23.3% of sham participants (P = 0.0001). The VFR was maintained through months 12 and 24: 53.1% and 50.3% in ocriplasmin versus 21.9% and 20.5% in sham participants, respectively (P < 0.0001). Resolution of VMA at day 28 significantly increased the odds of a VFR at each assessment period. Conclusions Treatment with ocriplasmin compared with sham resulted in a significant improvement in VFR. The 6-month treatment effect was sustained at months 12 and 24.

Ocriplasmin for Treatment of Vitreomacular Traction: An Update

Pharmacologic vitreolysis with ocriplasmin, a 27 kilodalton serine protease, is an effective nonsurgical treatment option for vitreomacular traction (VMT). Data from phase III clinical studies, including the Microplasmin for Intravitreal Injection-Traction Release without Surgical Treatment (MIVI-TRUST) and Ocriplasmin for Treatment for Symptomatic Vitreomacular Adhesion Including Macular Hole ...

Transient visual loss and delayed resolution of vitreomacular traction after intravitreal ocriplasmin

Vitreomacular traction and vitreomacular traction with macular hole are conditions associated with visual disturbance and decreased visual acuity. Recent studies have demonstrated that ocriplasmin is effective and safe in specific patient groups with vitreomacular traction, and hence is recommended as a treatment option. We present here a case report of a patient treated with intravitreal ocrip...

Ocriplasmin for Vitreoretinal Diseases

Fibronectin and laminin are clinically relevant plasmin receptors in the eye. Located at the vitreoretinal interface, they are cleaved by ocriplasmin (Microplasmin, ThromboGenics, Iselin, NJ), a novel ophthalmic medication. A series of clinical trials to study ocriplasmin for the treatment of vitreoretinal diseases such as vitreomacular traction, macular hole, and exudative age-related macular ...

Retinal breaks due to intravitreal ocriplasmin

Ocriplasmin represents a new treatment option for numerous vitreoretinopathies involving an abnormal vitreomacular interface. While the drug may circumvent the traditional risks of surgical treatment, pharmacologic vitreolysis is not devoid of risk itself. This report presents two cases, one of vitreomacular traction syndrome and the other of a full-thickness macular hole, both of which were tr...

Enzymatic vitreolysis with ocriplasmin for vitreomacular traction and macular holes.

BACKGROUND Vitreomacular adhesion can lead to pathologic traction and macular hole. The standard treatment for severe, symptomatic vitreomacular adhesion is vitrectomy. Ocriplasmin is a recombinant protease with activity against fibronectin and laminin, components of the vitreoretinal interface. METHODS We conducted two multicenter, randomized, double-blind, phase 3 clinical trials to compare...
