Disorders of choroid and retina

retinal degeneration characterized by gradual deterioration of light-sensing cells in the tissues at the back of the eye

retinal degeneration characterized by the gradual deterioration of the photoreceptors or the retinal pigment epithelium of the retina leading to progressive sight loss

eye disease that causes visual impairment, often temporary, usually in one eye; when the disorder is active, it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula

Chorioretinitis is an inflammation of the choroid (thin pigmented vascular coat of the eye) and retina of the eye. It is a form of posterior uveitis. Inflammation of these layers can lead to vision-threatening complications. If only the choroid is inflamed, not the retina, the condition is termed choroiditis. The ophthalmologist's goal in treating these potentially blinding conditions is to eliminate the inflammation and minimize the potential risk of therapy to the patient.

Choroideremia (; CHM) is a rare, X-linked recessive form of hereditary retinal degeneration that affects roughly 1 in 50,000 males. The disease causes a gradual loss of vision, starting with childhood night blindness, followed by peripheral vision loss and progressing to loss of central vision later in life. Progression continues throughout the individual's life, but both the rate of change and the degree of visual loss are variable among those affected, even within the same family.

Retinitis is inflammation of the retina in the eye, which can permanently damage the retina and lead to blindness. The retina is the eye's "sensing" tissue. Retinitis may be caused by a number of different infectious agents. Its most common form, called retinitis pigmentosa, has a prevalence of one in every 2,500–7,000 people. This condition is one of the leading causes that leads to blindness in patients in the age range of 20–60 years old.

disease of the eye in response to changes in the vitreous humor or more rarely, diabetes

macular degeneration that can cause progressive vision loss, it is characterized by the disruption of cells in a small area near the center of the retina, the macula

Retinoschisis is an eye disease characterized by the abnormal splitting of the retina's neurosensory layers, usually in the outer plexiform layer. Retinoschisis can be divided into degenerative forms which are very common and almost exclusively involve the peripheral retina and hereditary forms which are rare and involve the central retina and sometimes the peripheral retina. The degenerative forms are asymptomatic and involve the peripheral retina only and do not affect the visual acuity. Some rarer forms result in a loss of vision in the corresponding visual field.

retinitis that has material basis in Cytomegalovirus

retinal artery occlusion characterized by blockage of blood flow through the central retinal artery

eye disease in dogs

inherited ocular disorder characterized by the loss of cone cells

small break in the macula, located in the center of the eye's light-sensitive tissue called the retina

retinal vascular disease characterized by the prevention of blood vessel formation at the edges of the retina and the hemorrhage of the blood vessels in the retina
