Can you tell me the difference between macular dystrophy and macular degeneration?

Can you tell me the difference between macular dystrophy and macular degeneration?

Macular degeneration: A dystrophy is something a person is born with. A degeneration is an acquired condition that occurs as a person ages. Macular degeneration is a disease of older people, whereby the macula suffers progressive damage and the patient suffers visual loss, either slowly or rapidly. A macular dystrophy usually shows up earlier in life, with variable visual consequences, depending on the disorder.

What is the difference between macular dystrophy vs macular degeneration?

What is the difference between macular dystrophy vs macular degeneration?

Genetics: Macular dystrophy is often cause by a defect in a gene for macular function, while age-related macular degeneration is not (currently known) to be caused by a gene malfunction, but from oxidative damage over time to the macula. Essentially it's genetics vs environment.

Please help! What is the difference between macular dystrophy and macular degeneration?

Please help! What is the difference between macular dystrophy and macular degeneration?

Age of onset.: Typically, macular degeneration occurs in patients older than 55 years, and called age-related. There may be genetic associations as well. However, macular dystrophies are typically rare, inherited disorders occurring earlier in life which usually cause photoreceptor loss in the retina tissue. Both tend to cause central vision loss of varying degree. There is no effective treatment for dystrophy.

Can you compare and contrast the differences between glaucoma and macular degeneration?

Can you compare and contrast the differences between glaucoma and macular degeneration?

Eye diseases: Both are incurable. Both have recommended treatment algorithms. Glaucoma is a disease of the optic nerve that generally affects peripheral vision first and moves inward late in disease to affect center vision. Macular degeneration is a disease of the macula (center of vision), that slowly robs the ability to read and see centrally without affecting peripheral vision. Both generally aging diseases.

Is there a difference between macular degeneration and age-related macular degeneration?

Is there a difference between macular degeneration and age-related macular degeneration?

Technically yes: In general when people use the term 'macular degeneration' they are referring to the age-related form, but technically there are other types. Age-related macular degeneration is by far the most common, and the other and more rare forms are often hereditary and present much earlier in life.

What is the difference between macular degeneration and night blindness?

Well,: Night blindness is congenital, due to disease of the rods. Macular is a disease of the central retina, due to degeneration of the membrane that nourishes it.

What is the difference between macular degeneration & epiretinal membrane?

Totally different: Macualr degeneration is a condition that directly affects layers of the retina in the back of these that are responsible for light sensing (outer segments and RPE). The condition is usually present in the setting of having genetic suseptability. Epiretinal membrane grows on the inner surface of the retina. Is causes secondary retinal swelling and distortion affecting vision.

What is symptom of macular degeneration?

What is symptom of macular degeneration?

Decreased vision: Both the wet and dry forms of armd cause decrease in central vision. Distortion is often an early symptom and an amsler grid is a good self screening tool. Vision loss from the dry form is usually slowly progressive and lessor in degree than the wet form which can have very dramatic decrease in vision that is rapid and significant.

What is the first symptom of macular degeneration?

What is the first symptom of macular degeneration?

Vision changes: The first symptom most people experience with macular degeneration is a change in vision. An amsler grid is a simple screening tool available for home use that can allow patients who are at risk for macular degeneration to monitor for such changes.

What are the different kinds of macular degeneration?

Wet and Dry: There are two general forms: dry about 85% which is the slow breakdown of macular pigment and vision decrease. The wet form has a more rapid progression with formation of new blood vessels, severe vision loss and occasionally intraocular hemorrhage. There are new medications which can address this.

Is it rare for teenagers to have macular degeneration?

Very rare: The common type of macular degeneration is called amd, standing for "age-related macular degeneration", and the age is old age, usually over 60. However, there are rarer conditions of the retina that can lead to degeneration. Stargardt's disease, retinitis pigmentosa, pattern dystrophies of the retinal pigment epithelium, retinal cone dystrophies, and familial drusen can affect teens.

What happens to the vision if a person has macular degeneration?

What happens to the vision if a person has macular degeneration?

Fairly common: Macular degeneration was the most common cause of legal blindness in individuals over 50. With modern treatment strategies, severe vision loss is much less common. Some degree of vision impairment usually develops with this chronic degenerative disease over time. The earliest symptoms include delay in adjusting to dim light ; needing more light to read. Visual acuity decline follows.

AREDS vitamins: The national eye institute did a study that showed that a particular vitamin formula called areds can help reduce progression of macular degenration in people with high risk characteristics. You should see your ophthalmologist to determine if you have these characteristics. There are particular eye vitamins that your eye md may recommend for your general ocular health.

Macular degeneration--is it always in old people?

See below: Age-related macular degeneration (amd) only occurs in adults after one's forties. Diseases that may look like amd but happen earlier include macular dystrophy, best's disease, stargardt disease, among others. See a retina specialist.
