How much can you see when you've got Aniridia?

---

The Wikipedia article doesn't really make clear exactly how much you can see if you've got Aniridia. So how much can you see?
How much a patient with aniridia could see depends on different things-there are special made contact lenses and glasses with tint to prevent glare-it also depends on other anomalies that could be accompanying aniridia- briefly there is only one way to know consulting your specialist. because visual outcomes are different from eye to eye ,patient to patient .(concretely aniridia patients could never see as well as you do)  (+ info)

Is the genetic disorder aniridia a sex linked disease?

---

Is the genetic disorder aniridia a sex link disease, if so what sex is the carrier for the disease?
This is not a sex-linked disorder but, it is a rare, congenital absence or partial absence of the Iris. It is autosomal dominant trait or recessive hereditary pattern. It affects the eyes.

What negative effects does aniridia have?

---

Does it make your eyesight worse? Does it hurt to be in the sunlight? etc...
Aniridia is usually a congenital malformation of the iris, and presents as a black or red iris. Symptoms are usually nystagmus, sensitivity to light (so problems with glare) and poor vision.  (+ info)

Was anyone else born with congenitial cateracts,coloboma's or Aniridia?

---

I was born with cateract & coloboma's in both eye's,Daughter was born with Glaucoma & Aniridia,9 month old granddaughter was born with Aniridia.Anyone with any info on these rare eye disease"s that current?
Hi

My name is Hannah and I have aniridia, involving Cataracts and cornea disease.

I run the Aniridia Network and have meet and spoken to 100's of people with aniridia as well as doctors who treat people with aniridia have conduct studies into it.

I would have happy to answer any questions you have. You can email me at [email protected] hannah at aniridia dot org  (+ info)

please be kind to let me know where I can buy ANIRIDIA LENS and what would be the cost? Power +18?

---

please be kind to let me know where I can buy ANIRIDIA LENS and what would be the cost? Power +18. She is based in Hyderabad - South India. Her operation is due as we are not able to find this lens with power +18.
This site says it is available up to a + 30.00

The ophthalmologist doing the surgery should be able to get it.

Help on aniridia?

---

My friend has aniridia and is already blind in one eye, what can i do to help or get help for him to keep the other eye?
Aniridia is a genetic eye condition that is present at birth (congenital) and is almost always bilateral.
Aniridia literally means "without iris." In most cases this is the most visible sign of the condition. However, aniridia is caused when the gene responiable for eye development - the PAX6 gene - does not function correctly. This causes the eye to stop developing too early and when the baby is born most of the eye is underdeveloped to some degree. Some aniridic eyes are more developed than others and therefore it is difficult to say exactly how aniridia will progress in an individual, however, in general people with aniridia are prone to.
Medical Care:

* Prophylaxis is directed toward the prevention of glaucoma, which includes the following:

o Medical treatment with miotics

o Surgical separation of the iris from the trabecular meshwork in selected cases

* The medical treatment is directed toward control of intraocular pressure, which includes the topical use of the following:

o Miotics

o Beta-blockers

o Sympathomimetics

o Carbonic anhydrase inhibitors

* The chances of failure with local antiglaucoma treatment are high.

* Treatment of photophobia and nystagmus

o Tinted or iris contact lenses

o Tinted spectacle lenses

o Tinted intraocular lenses (IOLs)

o By the above measures, reducing the amplitude and frequency of nystagmus is possible.

* Treatment of refractive errors - Careful refraction and complete correction

* Treatment of amblyopia and strabismus

o Usually, the potential visual acuity in both eyes should be symmetrical.

o When the vision is unequal without structural difference, vigorous amblyopia exercises should be performed in the worst eye.

o Binocularity can be achieved if macular hypoplasia is not severe.

o Strabismus surgery is indicated at an early age.

Surgical Care:

* Management of cataract

o In-the-bag lens implantation in cases without lens dislocation

o In-the-bag IOL placement with intracapsular ring, when there is slight lens displacement

o Lens extraction followed by contact lens correction, if the lens is grossly out of place

* Management of glaucoma

o Goniotomy

+ Prophylactic

+ Early surgical therapy - Some risk to the crystalline lens and zonules exists because the surgery is performed from the anterior approach.

o Trabeculotomy is safer than goniotomy. The tissues can be defined more clearly, and accurate surgery can be performed. However, failures are common.

o Filtering procedures - Greater danger of injury to the crystalline lens and disturbance of the vitreous exists because the iris is absent.

o Laser therapy to angle abnormalities

o Cyclocryotherapy - Endocyclophotocoagulation in selected cases

o Glaucoma valve procedure - The choice of the techniques and the order in which they are used depends upon the peculiarities of the case and the perception of the surgeon.

Consultations:

* Banded chromosome analysis on the patient and both parents

* Linkage analysis when large families are available

* Genetic counseling

Who gets ANIRIDIA? [Race, gender, etc]?

I'm doing a project on it for my biology class, and I can't find anything on that specific question. I'm making an educated guess and saying "everyone can get it", but am I right?
I think its genetic but heres some info

Aniridia and Glaucoma - can anything be done?

---

I have a friend with aniridia and glaucoma. He's been blind in one eye for years already. If he goes blind in the other eye too, is there anything that can be done?

I don't know much about glaucoma, but I think it damages the optic nerve? Is there any possible way to regenerate or replace the optic nerve? If not, would any kind of transplant work?

If these are stupid, unheard of questions, I'm sorry. But he's my best friend and he doesn't deserve this at all. = (
And yes, unfortunately, he does have glaucoma in both eyes. He already takes meds for it.
Good questions! Glaucoma occurs when neurons in the the optic nerve are killed. Unfortunately, once they are dead there is no regeneration (yet discovered anyway), and no transplant will help. It sounds like your friend has some structural defect (anirida) that caused the glaucoma in one eye. Hopefully, the same defect is not present in the other. He needs to keep up with his appointments and will be put on meds if they ever find even the slightest possibility of glaucoma in his good eye.  (+ info)

Is it possible for Aniridia to cover the sclera?

---

I am working on a rather lengthy fantasy based story, but would like to have more realistic explanations for some of the oddities that occur in it. One of which is that a few of the characters have a specific eye quality where the entirety of the eye is a single solid color with no visible pupil. The closest thing to this that I could find through Google is a medical condition called Aniridia where there is no visible iris in the eye.
Is it possible for Aniridia to completely cover the sclera (white) of the eye? If not, is there another condition out there that might?
Since I'm Greek, I can mke you understand what "anirdia" is. Aniridia comes from Greek: αν + ίρις = ανιριδία => un + iris = aniridia so it means no iris. It exists only onto the iris part, not the sclera.  (+ info)
