ClinConnect Summary

This clinical trial is looking at how well certain tests can measure the effects of retinitis pigmentosa, a condition that causes vision loss. The study is being conducted at The Vision Research and Assessment Institute (VRAI), which is dedicated to helping people with low vision. They want to find out if these tests work effectively for patients with severe vision loss and help doctors understand the best ways to assess their patients' vision.

To participate, you need to be diagnosed with bilateral retinitis pigmentosa, meaning both of your eyes are affected, and have some level of vision loss that can be measured. Participants should be comfortable communicating in English. The study is open to both men and women aged 65 and older. If you join, you can expect to undergo various tests related to your vision, all conducted by experienced professionals in a supportive environment. It's important to note that if you have any significant cognitive issues that could affect your ability to complete the tests, you may not be eligible to participate.
