occurs after infancy. This condition may be seen in association with uncontrolled diabetes and certain types of cataracts. Antihypertensive drugs and other medications can also affect the refractive power of the lens

Yes, that is true. The male only needs to receive one defective copy, since a recessive gene becomes dominant when the other gene is missing -- and the Y chromosome generally cannot carry a healthy version of the gene. So most women who carry the gene are only carriers, since they usually have another X chromosome to balance it out. For women to get the typical forms of color blindness, they would have to get it from both parents, while men would only need to get it from the mother.

Now the rare form of colorblindness that impacts blue vision is not carried on the 23rd chromosomal pair, so everyone is equally likely to get it regardless of gender.

If you happen to be looking at a nuclear bomb without protection at the moment of explosion you will receive permanent retinal burns from the UV radiation. The US military actually did effects experiments in the 1950s using sheep with their eyelids clamped open so they could verify this and found "upside down mushroom shaped burns" on the retinas of those sheep.

Even with protection from the UV you may experience temporary flash blindness due to the brightness of the visible light bleaching the pigments in the rod and cone cells in the retina.

yes it is i would recommend spark eye care hospital in secunderabad. i had a best experience at reasonable price. it is a good hospital for retina related check up & regular eye check as well. their staff are good and polite. their diagnosis is perfect and treatment is also good. they would remind us followup calls their infrastructure is good

It is an eye condition that can lead to loss of vision. There are several variations of Glaucoma. Open Angle Glaucoma is common, slow to take effect, but progressively deteriorating. The number of people affected is high, up to 2% of the population over the age of 40. Vision loss in irreversible, treatment can slow the progression

Glaucoma is caused by the damage of optic nerves. Initially, it can cause peripheral vision loss and if not treated properly, it can lead to complete blindness. It is more common among people above age 50, but it is also caused for various other reasons like diabetes, family history, increased pressure in eye, myopia and so on. If you are having concerns about your eye health, it is highly recommended to consult a good optometrist from a good eye clinic like University Eye Clinic in Toronto. If detected early, glaucoma can be cured successfully using treatments like eye drops or laser surgery. Read more about glaucoma here: universityeyeclinic.com/glaucoma/ .

Unfortunately, glaucoma is one sneaky eye disorder. There is typically no pain and no noticeable symptoms. If you have glaucoma, you won't notice it until you have vision loss.

The early symptoms associated with chronic open angle glaucoma, the most common type, are usually unnoticeable. At first, in most cases, the build up of pressure is gradual without any discomfort or pain. Most people do not detect a change in their vision until substantial sight loss has occurred. Certain parts of peripheral (side) vision are affected first with the top, sides, and bottom of the field of vision becoming decreased. Later in the course of the disease central vision becomes affected, mild headaches and difficulty with night vision might be experienced. And if left untreated, total blindness will result.

High optic nerve pressure is associated with high CSF (cerebral spinal fluid) in the brain. The condition has two names: idiopathic Intercranial hypertension, or Pseudotumor Cerebri.

When the CSF level in the brain spikes, it causes fluid to back up an build up in the optic nerves. Pressure in the optic nerve and in the brain can be decreased with diuretics(such as Diamox). Pressure in the brain can be relieved by spinal taps, or a surgical procedure where a shunt is inserted into the brain. The fluid in the optic nerves can be decreased by a surgical procedure called Optic Nerve Sheath Fenestration.

When the trabeculum is blocked, pressure from the build up of aqueous humor either increases rapidly with pain and redness, or builds slowly with no symptoms until there is a significant loss of vision

The pressure within the eye(s) builds up causing horrible pain. once you're diagnosed you move to california, and find a doctor looking to make an extra 50 bucks. nee you end that Dr. get him to write you a lifetime prescription for medical marijuana. After that you get high off your butt every day and live happily ever after.

Yes, Glaucoma and Vertigo are linked as they both effect your vision. When you have glaucoma you see dark shadows or your vision is impared when you can not see at all. With vertigo again your vision is effected as your body is not balanced and you can not see clearly as well.

Abnormal curvature of the cornea can cause several conditions. When the curvature is excessively steep, it can lead to conditions such as keratoconus or pellucid marginal degeneration as a couple of examples. These conditions can lead to high degrees of nearsightedness, or myopia. In addition, when parts of the cornea are steeper than others in certain meridians, this can lead to astigmatism.

With astigmatism, the cornea is not perfectly round like a basketball but is curved more like an oval or football-shape. When light reaches the retina, it will not focus on one point but on multiple leading to blurred vision.

It can be if vision loss is extensive or does not respond to treatment, but as long as vision in the better eye is at 20/40 or better with glasses/contacts MEB may not be necessary and therefore no discharge. They will most likely monitor closely to be sure the condition does not worsen. If for some reason you feel it effects your job and feel you need discharged you can always request a med board.

during the first several years of elementary school when a teacher notices a child having difficulty seeing the chalkboard, reading, or concentrating. The teacher or school nurse often recommends an eye examination by an ophthalmologist or optometrist

In itself, most types of glaucoma are not life-threatening. Glaucoma causes damage to the optic nerve. There are four types of glaucoma and they are all characterized by increased pressure within the eyeball, which is what causes damage to the optic nerve.

However, certain medications used to treat glaucoma can have life-threatening side-effects. It is important that, if one is taking such medications, one remains regularly monitored by a doctor. "Closed-angle" glaucoma can also be life-threatening.

Yes, there have been several studies that have recently linked glaucoma and vertigo. These studies have also linked aging with glaucoma, vertigo, and diabetes.
