Atrophic Holes Atrophic retinal holes are full thickness retina breaks often existing in the peripheral retina. They are the result of atrophic changes within the sensory retina that are not induced by vitreous adhesions. Often, these lesions are found in association with lattice degeneration.

- Cerebral atrophy is a common feature of many of the diseases that affect the brain. Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them.Atrophy can be generalized, which means that all of the brain has shrunk; or it can be focal, affecting only a limited area of the brain and resulting in a decrease of the functions that area of the brain controls.n brain tissue, atrophy describes a loss of neurons and the connections between them.

What Is Retinitis Pigmentosa Retinitis Pigmentosa (RP) refers to a group of diseases which cause a slow but progressive vision loss. In each of them there is a gradual loss of the light-sensitive retinal cells called rods and cones. Most forms of RP are inherited or genetic, though its signs do not necessarily appear in every generation.

Cause of a hereditary form of blindness discovered Initially the occurrence of progressive retinal degeneration -- progressive retinal atrophy, in humans called retinitis pigmentosa -- had been identified in Schapendoes dogs. Retinitis pigmentosa is the most common hereditary disease which causes blindness in humans.

ATROPHY Atrophy is a form of cell adaptation in response to decreased trophic influences, decreased functional demands or decreased nutrition. Cellular Atrophy is a decrease in cell size caused by loss of subcellular organelles and substances. Organ Atrophy is a decrease in the tissue mass of an organ due to either a decrease in size of individual cells (cellular atrophy), a decrease in number of cells, or both.

Progressive Retinal Atrophy (PRA) in Dogs PRA is a blinding disease in most affected dogs, but in the opinion of many veterinary ophthalmologists, including Dr. McCalla, PRA is no longer a hopeless disease.New insight into the mechanisms of retinal damage from oxidative stress has resulted in much more hope for prolonging the vision of affected dogs.hat to do if you suspect your dog has PRA: Don’t give up! PRA is no longer a hopeless disease. Have your dog examined by a board-certified veterinary ophthalmologist to determine if PRA is indeed present.

atrophy Atrophy resulting from disease of the tissue itself, or loss of trophic support due to other disease is termed pathological atrophy. Shrinkage in the size of the cell by loss of cell substance is known as atrophy. It represents a form of adaptive response and may culminate in cell death.ormonal and nerve inputs that maintain an organ or body part are referred to as trophic. Atrophy is a general physiological process of reabsorption and breakdown of tissues, involving apoptosis on a cellular level. It can be part of normal body development and homeostatic processes, or as a result of disease.

Acquired Retinal Astrocytoma Abstract. 1  Acquired retinal astrocytoma is a rare intraretinal tumor, appearing as a yellow-white ­nodular mass of the retina. This tumor resembles retinal astrocytic hamartoma, and it is rarely associated with tuberous sclerosis. 2  Acquired retinal astrocytoma is a very rare intraretinal tumor.

But atherosclerosis can exist alone, often through clinical arteriosclerotic retinopathy as an important basis to measure blood pressure and arteriosclerosis.

Overview Vaginal atrophy (atrophic vaginitis) is thinning, drying and inflammation of the vaginal walls due to your body having less estrogen. Vaginal atrophy occurs most often after menopause. For many women, vaginal atrophy not only makes intercourse painful, but also leads to distressing urinary symptoms.

Porokeratosis Porokeratosis is a clonal disorder of keratinization characterized by one or more atrophic patches surrounded by a clinically and histologically distinctive hyperkeratotic ridgelike border called the cornoid lamella.Multiple clinical variants of porokeratosis are recognized.mmunosuppression may induce new lesions or cause preexisting lesions to flare. New lesions of porokeratosis have occurred as quickly as 4 months after initiation of immunosuppressive therapy, or as long as 14 years and may resolve following cessation of immunosuppressive therapy.

Optic Atrophy Disease Entity. Optic atrophy refers to the death of the retinal ganglion cell axons that comprise the optic nerve with the resulting picture of a pale optic nerve on funduscopy. Optic atrophy is an end stage that arises from myriad causes of optic nerve damage anywhere along the path from the retina to the lateral geniculate.

Vaginal Atrophy (Atrophic Vaginitis) Vaginal atrophy is a change of the vagina that develops when there is a significant decrease in levels of the female hormone estrogen. The condition also is called atrophic vaginitis. Estrogen, which is produced by the ovaries, plays a vital role in keeping vaginal tissues lubricated and healthy.

Proliferative Vitreo-Retinopathy Norman D. Radtke, MD. Proliferative vitreo-retinopathy (PVR) is the most common cause of failed repair of a retinal detachment and occurs when scar tissue creates traction on the retina.VR is characterized by proliferation of retinal pigment epithelial cells, glial cells, and inflammatory cells on the surface of the retina and within the vitreous gel. Traction is the key feature in the pathogenesis of PVR. The location, extent and severity of traction vary substantially.

Retinopathy In proliferative retinopathy, new, structurally unstable blood vessels grow on the surface of the retina. These unstable blood vessels cause frequent minor bleeding. The bleeding causes local irritation and scarring.Proliferative retinopathy can cause retinal detachment. This is a separation of the layers of the retina. It is one of the most serious consequences of proliferative retinopathy.The vitreous is the clear gel between the lens and the retina.
