I have hereditary short eyesight which developed at puberty. Can laser eye surgery fix this?

---

Blurry vision is not hereditary. It is a learned behavior which can be unlearned.

Because blurry vision is learned during times of stress our vision, even lasered, is at risk of getting worse. Many people have blurr again one to three years after LASIK surgery.  (+ info)

Are physical disabilities hereditary? Can they be passed down to my children?

---

I have a physically noticeable disability, which I've had since birth. Although it is noticeable, if I wear sunglasses I can easily cover it up. My left eye is completely blind, shut at all times and my eyebrows are a bit raised. To those with no prior knowledge, it could seem as if I'd been in a fight or a mild car accident. Nothing else on my body is affected.

I now find myself an expecting father and I am concerned about passing this disability on. Where can I find a source which deals with physical, as in affecting one's structural appearance, disabilities/defects. Most sites that I have found deal with hereditary issues such as diseases.
Although the internet is a wonderful place to gather information, there is risk in self-diagnosis. This is especially true in situations where hereditary issues are of concern. For example, some forms of muscular dystrophy are x-linked, while others are recessive. This difference has tremendous impact on prediction of what will occur in future generations. Conversely, not all birth defects are hereditary, some are just plain congenital anomalies.

While pediatricians and OB/Gyns are good with the common hereditary disorders, most are unfamiliar with the rarer ones. My suggestion would be to consult an MD who is a boarded clinical geneticist.  (+ info)

what are the other diseases related to eyelid muscles besides ptosis that cause difference in eye size?

---

the difference in eye size is specifically noted when the head its tilted or while looking down or when the cheek goes up while laughing or smiling. here, the eyelid of one eye raises while the other eyelid is normal.
When you say eye size, I assume you mean the amount of your eye that you can see between your upper & lower eye lid (?)....if this is the case (this is a ptosis & there are MANY types), then I want to tell you about a number of diseases that can cause this:

Myasthenia gravis (more common in diabetes patients), Myotonic dystrophy, Ocular myopathy are all diseases that commonly cause a type of ptosis called Myogenic ptosis. This is a ptosis that results from an abnormal functioning muscle. You mentioned that the difference in size was larger in some positions of gaze (ex. while looking down). A myogenic ptosis could explain this.

Another very common cause for this difference in size is a class of ptosis called Neurogenic ptosis (has there been a recent stroke, seizure...?). This includes a cranial nerve 3 palsy (or misdirection), and Horner's syndrome. Specifically, it can lead to a condition called "Marcus Gunn jaw winking" syndrome. This would help explain the difference in palpebral fissure size (distance between upper & lower lid) while smiling vs while not smiling. Classically, this condition is easily seen while the patient is eating/chewing.

A Mechanical ptosis can occurs from to edema (swelling) or tumors of the upper lid. If you recently have had eye/lid surgery, you may have an Aponeurotic ptosis.

Aside from a true ptosis, this may be due to something known as dermatochalasis. This is simply when excess skin in the upper lid hangs down. Lastly, if you are asking regarding a child/infant, you'll want to consider a Congenital ptosis.

Sometimes patients will think that their palpebral fissure size is decreasing....while in fact it is not decreasing, but the other eye's palpebral fissure size is increasing. The palpebral fissure size of the other eye can increase for many reasons: drug use, space occupying mass behind the eye pushing it forward, and many other reasons.

Best of Luck! If this condition had an acute onset (you noticed it all of the sudden), then it is my recommendation to go see an eye doctor ASAP.  (+ info)

I would like to know if my child will be left handed and whether the kid will inherit any hereditary diseases.

---

I was left handed. My dad had changed me to use my right hand and now I use my right hand. In my family, me and my father's younger brother are the only people who got the left handed tendency. My uncle's (left handed) kids are all right handed from birth. My mom and dad are both right handed. My husband's family is also right handed.

About hereditary diseases, in my side , my dad's family doesnt have any particular hereditary disease, my mom's side, my grandmom is diabetic. My husband's side, his mom was diabetic and dad has triglyceride. My husband has asthma lightly. I am not a mother yet. But just wanted to know everything in advance.
My Goodness !
Why would it matter if you had a child who was left handed ?
There seem to be several auto immune diseases in your family and there is no way to know ahead of time how healthy your future child will be.
You could go for genetic counseling but I don't see the reason.
You will do whatever you have to do for your child regardless of any ailments he/she has.
I wish you the best.  (+ info)

What's better at detecting orbit (eye) diseases- Orbit MRI or a Orbit CT Scan?

---

Orbit MRI or a Orbit CT Scan?
Depends on what your suspicion is. MRI would probably be better for things like a choroidal tumor, but a CT would be great for something like an orbital osteoma.  (+ info)

Interesting or strange hereditary diseases?

Does anyone know of any strange/interesting hereditary diseases and a source if possible?
'Phenylketonuria (PKU) is an inborn error of metabolism that is detectable during the first days of life with appropriate blood testing (e.g., during routine neonatal screening). PKU is characterized by absence or deficiency of an enzyme (phenylalanine hydroxylase) that is responsible for processing the essential amino acid phenylalanine. (Amino acids, the chemical building blocks of proteins, are essential for proper growth and development.) With normal enzymatic activity, phenylalanine is converted to another amino acid (tyrosine), which is then utilized by the body. However, when the phenylalanine hydroxylase enzyme is absent or deficient, phenylalanine abnormally accumulates in the blood and is toxic to brain tissue.'

NORD's Rare Disease Database (link) is THE clearinghouse on rare diseas and conditions.

It is a great source of information for those so inclined. : )

Hope this helps.  (+ info)

Can a regular eye exam from from an opthemetrist detect diseases and disorders in the eye ?

---

My eyes having been hurting me since i started plaing my xbox excessively, even when i stopped the pain still went on... it's been a month now and i still have the pain and my vision gets kindas glarey when i try to watch anything 3d or when i look at the digital alrm clock.. i'm also having headaches which as lasted up until a month now and painkillers don't do much.. i think i might have the dry eyes syndromn but i don't know whether or not a regular eye exam from an optemetrist can detect and diagnose my problems.
You should see an opthalmologist as soon as possible. But, depending on where you are, I think you need to get a referred by a GP or optometrist.

The main job of optometrists is in the optical field i.e. diagnosing refractive errors such as myopia. They also diagnose and treat various eye diseases. However, that is not their primary role, and you that's why you should go to an ophthalmologist.

Opthalmologists on the other hand specialise in the anatomy of the eye and surgical procedures.

Don't worry! But you should go make an appointment asap, to make sure.

Also, you should have ideally have an yearly examination with your optometrist. Such examinations are covered by health insurance in many countries.  (+ info)

screening for hereditary genetic diseases?

---

What steps should I take to screen for rare genetic diseases to find out wether or not they run in my family.I want to do this before I have a child and not get surprised after nine months.
I had to get genetic testing because I have a trait that could have affected my shildren. I also had to get genetic counseling. What you have to do is ask your doctor for a simple blood test that can find any possible genetic traits. If they find something then you can be referred to genetic counseling. It's scary. I have a trait called Mediterranean Thalyssemia. They told me that if my spouse had the trait there would be a one in four chance that the baby could come out with a severe blood disorder (luckily my hubby did not have the trait. They ask you about your family history and everything.  (+ info)
