ClinConnect Summary

This clinical trial is studying a surgical procedure called pars plana vitrectomy, which involves removing the vitreous gel from the eye, to treat a condition known as hypermyopic foveoschisis. This condition affects the central part of the retina and can lead to serious vision problems, like a macular hole. The trial is specifically looking at the safety and effectiveness of using silicone oil to help support the eye after surgery, without removing a layer of retina called the internal limiting membrane.

To be eligible for this study, participants should be between the ages of 65 and 74, have significant vision challenges, and meet specific eye measurement criteria. For instance, they must have a certain degree of nearsightedness or a particular eye length. Participants will be closely monitored throughout the study to ensure their safety and to observe how well the surgery works. It's important to note that individuals with certain eye diseases or conditions might not qualify, as the focus is on those who specifically have hypermyopic foveoschisis without other complicating factors.
