\An anatomical structure that consists of the maximal set of organ parts so connected to one another that together they constitute a self-contained unit of macroscopic anatomy, distinct both morphologically and functionally from other such units. Together with other organs, an organ constitutes an organ system or a body part. An organ is divisible into organ parts but not organs (examples: femur, biceps, liver, heart, aorta, sciatic nerve, ovary).\Structure of sensory organ\Eye structure\Eye proper part (body structure)\...

Cone 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.
