Label	Id	Description
Retinal Dysplasia	D015792	[Congenital, often bilateral, retinal abnormality characterized by the arrangement of outer nuclear retinal cells in a palisading or radiating pattern surrounding a central ocular space. This disorder is sometimes hereditary.]
Retinal Dystrophies	D058499	[A group of disorders involving predominantly the posterior portion of the ocular fundus, due to degeneration in the sensory layer of the RETINA; RETINAL PIGMENT EPITHELIUM; BRUCH MEMBRANE; CHOROID; or a combination of these tissues.]
Retinal Hemorrhage	D012166	[Bleeding from the vessels of the retina.]
Retinal Necrosis Syndrome, Acute	D015882	[Mild to fulminant necrotizing vaso-occlusive retinitis associated with a high incidence of retinal detachment and poor vision outcome.]
Retinal Neoplasms	D019572	[Tumors or cancer of the RETINA.]
Retinal Neovascularization	D015861	[Formation of new blood vessels originating from the retinal veins and extending along the inner (vitreal) surface of the retina.]
Retinal Perforations	D012167	[Perforations through the whole thickness of the retina including the macula as the result of inflammation, trauma, degeneration, etc. The concept includes retinal breaks, tears, dialyses, and holes.]
Retinal Telangiectasis	D058456	[A group of rare, idiopathic, congenital retinal vascular anomalies affecting the retinal capillaries. It is characterized by dilation and tortuosity of retinal vessels and formation of multiple aneurysms, with different degrees of leakage and exudates emanating from the blood vessels.]
Retinal Vasculitis	D031300	[Inflammation of the retinal vasculature with various causes including infectious disease; LUPUS ERYTHEMATOSUS, SYSTEMIC; MULTIPLE SCLEROSIS; BEHCET SYNDROME; and CHORIORETINITIS.]
Retinal Vein Occlusion	D012170	[Blockage of the RETINAL VEIN. Those at high risk for this condition include patients with HYPERTENSION; DIABETES MELLITUS; ATHEROSCLEROSIS; and other CARDIOVASCULAR DISEASES.]
Retinitis	D012173	[Inflammation of the RETINA. It is rarely limited to the retina, but is commonly associated with diseases of the choroid (CHORIORETINITIS) and of the OPTIC DISK (neuroretinitis).]
Retinitis Pigmentosa	D012174	[Hereditary, progressive degeneration of the retina due to death of ROD PHOTORECEPTORS initially and subsequent death of CONE PHOTORECEPTORS. It is characterized by deposition of pigment in the retina.]
Retinoblastoma	D012175	[A malignant tumor arising from the nuclear layer of the retina that is the most common primary tumor of the eye in children. The tumor tends to occur in early childhood or infancy and may be present at birth. The majority are sporadic, but the condition may be transmitted as an autosomal dominant trait. Histologic features include dense cellularity, small round polygonal cells, and areas of calcification and necrosis. An abnormal pupil reflex (leukokoria); NYSTAGMUS, PATHOLOGIC; STRABISMUS; and visual loss represent common clinical characteristics of this condition. (From DeVita et al., Cancer: Principles and Practice of Oncology, 5th ed, p2104)]
Retinopathy of Prematurity	D012178	[A bilateral retinopathy occurring in premature infants treated with excessively high concentrations of oxygen, characterized by vascular dilatation, proliferation, and tortuosity, edema, and retinal detachment, with ultimate conversion of the retina into a fibrous mass that can be seen as a dense retrolental membrane. Usually growth of the eye is arrested and may result in microophthalmia, and blindness may occur. (Dorland, 27th ed)]
Retinoschisis	D041441	[A vitreoretinal dystrophy characterized by splitting of the neuroretinal layers. It occurs in two forms: degenerative retinoschisis and X chromosome-linked juvenile retinoschisis., Splitting of the RETINA into two layers at the level of the outer plexiform layer, beginning as a cystic degeneration in the extreme retinal periphery. It usually occurs after 40 years of age and is generally not progressive., X chromosome recessive disorder, found nearly exclusively in males and becoming apparent around puberty. Characterized initially by a cystlike structure involving the FOVEA CENTRALIS, a peripheral retinoschisis occurs in about half the patients.]
Retrobulbar Hemorrhage	D019315	[Hemorrhage within the orbital cavity, posterior to the eyeball.]
Retrocaval Ureter	D064749	[A rare congenital abnormality resulting in the URETER passing dorsal to and being obstructed by the INFERIOR VENA CAVA.]
Retrocochlear Diseases	D012181	[Pathological processes involving the VESTIBULOCOCHLEAR NERVE; BRAINSTEM; or CENTRAL NERVOUS SYSTEM. When hearing loss is due to retrocochlear pathology, it is called retrocochlear hearing loss.]
Retrognathia	D063173	[A physical misalignment of the upper (maxilla) and lower (mandibular) jaw bones in which either or both recede relative to the frontal plane of the forehead., The condition or state of a person suffering from retrognathia.]
Retrograde Degeneration	D012183	[Pathologic changes that occur in the axon and cell body of a neuron proximal to an axonal lesion. The process is characterized by central chromatolysis which features flattening and displacement of the nucleus, loss of Nissl bodies, and cellular edema. Central chromatolysis primarily occurs in lower motor neurons.]
