Effects of Pneumatic Vitreolysis on Macular Hole

Not Applicable
Completed
Conditions
Full-thickness Macular Holes (MH)
Vitreomacular Traction (VMT)

Device: Intraocular gas (C3F8)
Registration Number
NCT03677869
Lead Sponsor
Jaeb Center for Health Research
Brief Summary

Eyes with vitreomacular traction (VMT) and full-thickness macular holes (MH) will be enrolled into a non-randomized cohort treated with pneumatic vitreolysis (PVL) to determine the proportion with VMT release and MH closure and to assess factors associated with success.

Detailed Description

The objective of this trial is to obtain estimates of the proportion of eyes with MH closure of the inner retinal layers for eyes with VMT and full-thickness MHs treated with PVL. Understanding the rates of VMT release and MH closures in eyes with full-thickness MH treated with PVL is of interest. Surgery would result in nearly 100% hole closure and VMT release, making vitrectomy a poor control group choice. Spontaneous resolution of MH is highly unlikely, making an observation arm unnecessary. Therefore, these eyes will be enrolled into a non-randomized cohort treated with PVL to assess the outcomes of treatment.

Primary Outcome Measures
NameTimeMethod
Proportion of Eyes With Macular Hole Closure of Inner Retinal Layers Without Rescue Vitrectomyat 8 weeks
Secondary Outcome Measures
NameTimeMethod
No Macular Hole Closure Despite Rescue Vitrectomy8 weeks
Mean Change in E-ETDRS Visual Acuity Letter Score From BaselineBaseline to 8 weeks

Best-corrected visual acuity following protocol-defined refraction. Visual Acuity was measured with the Electronic Early Treatment Diabetic Retinopathy Study (E-ETDRS) visual acuity test on a scale from 100 letters (Snellen equivalent of 20/10) to 0 letters (Snellen equivalent \<20/800). Higher scores indicate better visual acuity and lower scores indicate worse visual acuity.
