Cone dystrophy with supernormal rod response
MONDO:0012475Cone dystrophy with supernormal rod response (CDSRR) is an inherited retinopathy, with an onset in the first or second decade of life, characterized by poor visual acuity (due to central scotoma), photophobia, severe dyschromatopsia, and occasionally, nystagmus. Night blindness usually develops later in the course of the disease, but it can also be apparent from childhood. A hallmark of CDSRR is the decreased and delayed dark-adapted response to dim flashes in electroretinographic recordings, which contrasts with the supernormal b-wave response at the highest levels of stimulation.
Also known as: cone dystrophy with supernormal rod ERG, cone dystrophy with supernormal rod electroretinogram, cone dystrophy with supernormal rod response, cone dystrophy with supernormal scotopic electroretinogram, retinal cone dystrophy type 3B, RCD3B, cone dystrophy with night blindness and supernormal Rod responses, Kcnv2-related, cone dystrophy with night blindness and supernormal rod responses KCNV2 related

New eye camera could spot retinal disease earlier
Knowledge-focused Not yet recruitingThis study will test a new, noninvasive camera called XyCAM CRE that measures blood flow in the back of the eye. Researchers will compare its images with standard eye tests in 350 adults with retinal disorders. The goal is to see if this camera can provide extra information to he…

Scientists track eye disease patterns to speed future cures
Knowledge-focused Not yet recruitingThis study looks back at medical records of 200 people with inherited retinal diseases, like retinitis pigmentosa and Stargardt disease. Researchers will analyze vision tests and eye scans to see how these diseases progress and how genetics affect symptoms. The goal is to find be…
