Retinitis Pigmentosa

Background The name retinitis pigmentosa (RP) was first applied by Dr Donders in 1857. It is the phenotypic description of several related, yet distinct, hereditary, progressive dystrophies of the photoreceptors of the retina and of the pigment epithelium (which lies just underneath the photoreceptors). Patients[…] [patient.info]

Retinal Detachment

What is the retina? The retina is the thin layer of light-sensing nerve cells lining the inside back of your eye. It converts light rays into signals, which are sent through the optic nerve to your brain where they are recognized as images. An eye is like a camera. The cornea and lens in the front of the eye[…] [ohsu.edu]
