Arm && Interventions

Group	Intervention	Description
Ocriplasmin	Ocriplasmin 0.125 mg in a 0.1 mL volume	Ocriplasmin 0.125 mg in a 0.1 mL volume administered as a single dose by intravitreal (IVT) injection

Primary Outcome Measures

Name	Time	Method
Percentage of Subjects With Non-surgical Resolution of Focal VMT/sVMA at Day 28, as Determined by Central Reading Center (CRC) Spectral Domain Optical Coherence Tomography (SD-OCT) Evaluation	Day 28	Vitreous separation was assessed, by SD-OCT according to CRC OCT image reading, into 1 of 12 categories, where the targeted status of VMA resolution was 7=Vitreous attached only at optic nerve (ON) or at ON and elsewhere, but not attached in macular, 9=Vitreous visible with complete separation and no attachment, and 10=No visible vitreous separation, which needed to be reached without prior vitrectomy. The assessment of resolution of VMT/sVMA was based upon the anatomical resolution of VMA only, i.e. no resolution of the related symptoms was considered. One eye (study eye) contributed to the analysis.

Secondary Outcome Measures

Name	Time	Method
Change From Baseline in Best-corrected Visual Acuity (BCVA) at Distance at Days 7, 28, 90, and 180	Baseline (Day 0), Day 7, Day 28, Day 90, Day 180	BCVA was assessed using Early Treatment Diabetic Retinopathy Study (ETDRS) testing. BCVA was determined as follows: if tested at 4 meters, BCVA=the number of letters read correctly at 4 meters+30; if tested at 1 meter, BCVA=the number of letters read correctly at 1 meter, with 83-84 representing normal vision. BCVA change was defined as a change in letters read from the baseline assessment. A positive change value indicates improvement. One eye (study eye) contributed to the analysis.
Percentage of Subjects With Closure of Macular Hole (MH), at Days 7, 28, 90, and 180 (if Present at Baseline)	Day 7, Day 28, Day 90, Day 180	The closure of macular hole (a full thickness defect of the retinal tissue involving the anatomical fovea) is defined as a flattened and reattached hole rim along the whole circumference of macular hole. Closure was determined by SD-OCT evaluation and the percentage of subjects tabulated. One eye (study eye) contributed to the analysis.
Percentage of Subjects With Non-surgical Resolution of VMT/sVMA at Days 7, 90, and 180	Baseline (Day 0), Day 7, Day 90, Day 180	As described in Primary Outcome Measure
Percentage of Subjects Experiencing Pars Plana Vitrectomy (PPV) at Day 180	Day 180	Pars plana vitrectomy (the surgical removal of vitreous gel from the eye) was captured in Concomitant Ocular Procedures. One eye (study eye) contributed to the analysis.
Change From Baseline in Central Foveal Thickness at Days 28 and 180	Baseline (Day 0), Day 28, Day 180	Central foveal thickness (CFT) was determined by subtracting the measurements in subretinal fluid (SRF) and retinal pigment epithelium (RPE) elevation and/or subretinal hyper-reflective material (SHRM) from the value in total retinal measurement. The change was defined as a change from baseline values of CFT. One eye (study eye) contributed to the analysis.
