Nowadays, every person has eye issues. It can be major or minor and we are the main cause of this disease. Some are minor that can be treated; or some may disappear by time. But some are major that can be treated only with surgery or laser treatment but there are some major eye problems that can’t even be treated. There are some minor eyes issues like; eyestrain, red eyes, etc.
Now here are some major issues or diseases of eyes like night blindness, colour blindness, uveitis, cataracts, retinal diseases, optic neuritis, macular degeneration, glaucoma, conjunctivitis, diabetic eye problems etc.
cataracts:- A clouding of lens which is behind iris and pupil is called cataract. It mainly causes to old people, who have reached 40 years of age and above. The main cause; or we can say the principle cause of blindness is cataract worldwide then there are glaucoma, macular degeneration, and diabetic retinopathy. There are types of cataracts worldwide including:
Sub-capsular cataract: – this type of cataract appears at the back of the lens. This type of cataract is caused to those who have chronic diabetes or those who take steroid they have the greater risk of having cataract.
Nuclear cataract: – This disease causes at the deep in the part of the lens. This disease is greatly or mainly caused to aged people which are 40 above.
Cortical cataract:- This type of cataract appear at the lens cortex which is the part of the lens that surrounds the central nucleus . It is characterized by White, wedge-like opacities that start at the periphery of the lens and start spreading to the centre.
Optic neuritis :- Optic neuritis is a part of the eye which carries visual information to the brain .Optic neuritis (ON) in which a person’s optic nerve become inflamed it can appear suddenly due to infection or a nerve disease.
Inflammation usually causes temporary vision loss that only happens in one eye. Some people with this disease experience pain but with proper treatment and time the person can recover from it and vision can even return. Optic neuritis doesn’t require treatment sometime it can be treated with mediation such as corticosteroids. It helps the patient to recover faster. But it requires more time at least 12 months to gain full recovery.
How does the retinal tear happens?
Sometimes vitreous moves away from retina without causing any problem. But at some cases vitreous pulls heard enough that it tears the retina apart. This fluid moves the retina to the back of the eye just like when wallpaper is pulled off from the wall.
Macular degeneration :- These days macular degeneration is the leading cause of vision loss it has effected more than 10 million Americans; more than cataract or glaucoma and at this present time macular degeneration is an incurable disease. Macula means the centrall part of the retina that’s the area where this disease is caused. Macula is the main cause for focusing our vision and it provides us the ability to read, drive, and to recognise face or colour. Due to macular degeneration we are not able to get the high quality of the images we use to get. At the starting of macular degeneration the vision is not affected if the disease start’s growing the patient will first get a blur vision then it keep getting worse. There are some types of macular degeneration early AMD, intermediate AMD, late AMD.
Glaucoma:- this disease more happens when pressure is created within the eye this pressure is cause of the fluid at back of the eye which damages the optic nerve but with diagnose and cure you can get your vision back.
Conjunctivitis:- This disease cause the conjunctiva to swell it line-up our eyelid and eye surface when this disease appears it gets red and swollen; and irritation and infection start spreading. It is not that serious it can be treated with medical treatment and it will be gone in 7 to 10 days.
Diabetic eye problems such as diabetic retinopathy and diabetic macular edema:-
This disease is caused to diabetic patient with a group of eye conditions. The conditions are diabetic retinopathy, diabetic macular edema, cataract, glaucoma. Diabetic retinopathy includes changes in the retinal blood that make then leak blood from eyes this disease is the most common cause of vision loss among people with diabetes. DME this causes the swelling of the retina which is called macula.
We should take care of our eyes; it is the most important part in our body if we have these diseases whether it is minor or major we should take precaution. And prevent it from spreading if we have major problem prefer to a good doctor. This report provides the main causes of vision loss and eye disease. If you understand the consequences than take precaution as or meet a good eye doctor as soon as possible.
