RUPTURE GLOBE

Rupture globe occurs when the integrity of the outer membranes of the eye is disrupted by blunt or penetrating trauma. Any full-thickness injury to the cornea, sclera, or both is considered an open globe injury. Globe rupture represents a major ophthalmologic emergency and always requires surgical intervention. damage to the posterior segment of the eye is associated with a very high frequency of permanent visual loss. Early recognition and ophthalmologic intervention are critical to maximizing functional outcome.

Alkali chemicals are more destructive then acidic chemicals because of their ability to adhere to the eye and penetrate tissues.more detail.....
CATARACT

A cataract is an opacity that develops in the lens of the eye, which lies behind the iris and the pupil.The lens works much like a camera lens, focusing light onto the retina at the back of the eye. The lens also adjusts the eye's focus, letting us see things clearly both up close and far away.
Cataracts develop from a variety of reasons, including long-term ultraviolet exposure,exposure to radiation, secondary effects of diseases such as diabetes, or simply due to advanced age; they are usually a result of Denaturation of lens. genetic factors are often a cause of congenital cataracts and positive family history may also play a role in predisposing someone to cataracts at an earlier age, a phenomenon of "anticipation" in pre-senile cataracts. Cataracts may also be produced by eye injury.read more....

RETINAL DETACTMENT

The retina is the light-sensitive tissue that lies smoothly againts the inside back wall of the eye and send message to the brain tghrough the optic nerve. Underneath retina is the coroid - a thin layer of blood vessel that supplies oxigyn and nutrients to the retina. Retinal detatchment happened when the retina separates from the coroid.

The retinal detatchment is when part of the retina either tears or pulls away (detaches) from the back of the eye. If it does, that part of the retina cannot gather light. Vision loss may occur. Tears or detachment may be caused by aging, an eye injury, or another eye problem.MORE detail......
. Retinal detacthment is amedical emergency, and time is critical. unless the detached retina is promptly surgically reattached. This condition can cause permanent loss of vision.

SIGN AND SYMTOMS
Retinal detachtment is painless, warning sign retinal detachtment is :
a. the sudden appearance of many foater.
b. flashes of light one or both eyes.
c. sudden loss in vision.
d. a shadow or curtain over a portion of the visual field.
