Eye Disorder-Infection,Types And Treatment.
Below we will be discussing types of eye disorder, eye infections and their treatment. The following below are types of eye problems :
INFECTION OF THE TEAR SAC (Dacryocystitis)
Dacryocystitis is an infection of the tears sac. This is caused when the nasolacrimal duct is blocked.
- There is Pain and swelling beneath the eye and next to the nose.
- The eye waters a lot.
- A drop of pus may appear in the corner of the eye when the swelling is gently pressed.
- Apply hot compresses.
- Put antibiotic eye drops or ointment in the eye.
- Take penicillin.
TROUBLE SEEING CLEARLY
Children who have trouble seeing clearly or who get headaches or eye pain when they read may need glasses. Have their eyes examined as early as possible (best around 4 years old).
In older persons, it is normal that with passing years, it becomes more difficult to see close things clearly. Reading glasses often help. Pick glasses that let you see clearly about 40 cm (15 inches) away from your eyes. If glasses do not help, see an eye doctor.
CROSS-EYE AND A WANDERING OR LAZY EYE (Strabismus, Squint)
If the eye sometimes wanders, but sometimes looks ahead normally, usually you need not to worry. The eye will grow straighter in time. But if the eye is always turned in the wrong way and if the child is not treated at a very early age, he or she may never see well with that eye.
See an eye doctor as soon as possible to find out if patching of the good eye, surgery or special glasses might help.
NOTE : Surgery done at a later age can usually straighten the eye and improve the child’s appearance but it will not help the weak eye see better.
A sty is a swollen lump on the eyelid, usually near its edge. To treat this, apply warm, moist compresses with a little salt in the water. Use of an antibiotic eye ointment; 3 times a day will help prevent more sties from occurring.
This is a fleshy thickening on the eye surface that slowly grows out from the edge of the eye near the nose and onto the cornea; this is caused by sunlight, wind and dust.
Dark glasses may help calm irritation and slow the growth of a pterygium. It should be removed by surgery before it reaches the pupil. Unfortunately, it may grow back again.
Treatments using powdered shells do more harm than good. However, eye drops of camomile tea (well boiled and without sugar) may help calm itching and burning. Also use cold compresses.
A SCRAPE, ULCER OR SCAR ON THE CORNEA
When the very thin, delicate surface of the cornea has been scraped, or damaged by infection, a painful corneal ulcer may result. If you look hard in a good light, you may see a grayish or less shiny patch on the surface of the cornea.
If not well cared for, a corneal ulcer can cause blindness. Apply antibiotic eye ointment 4 times a day for 7 days, give penicillin and cover the eye with a patch. If the eye is not better in 2 days, get immediate medical help.
A corneal scar is a painless, white patch on the cornea. It may result from a corneal ulcer, burn or other injury to the eye. Surgery (corneal transplant) is the only treatment. This is expensive and does not always give good results. Surgery should only be done if the person is blind but can still see light.
BLEEDING IN THE WHITE PART OF THE EYE
This is a painless, blood red patch in the white part of the eye which occasionally appears after lifting something heavy, coughing hard (as with whooping cough) or being hit on the eye.
The condition results from the bursting of a small blood vessel. It is harmless and will slowly disappear without treatment in about 2 weeks. Small red patches are common on the eyes of newborn babies. No treatment is needed.
BLEEDING BEHIND THE CORNEA (Hyphema)
The blood behind the cornea is a dangerous sign. It usually results from an injury to the eye with a blunt object like a fist. If there is pain, and loss of sight, refer the person to an eye doctor immediately.
If the pain is mild and there is no loss of sight, patch both eyes and keep the person at rest in bed for several days. If after a few days and the pain becomes much worse, there is probably hardening of the eye (glaucoma). Take the person to an eye doctor at once.
PUS BEHIND THE CORNEA (Hypopyon)
Pus behind the cornea is a sign of severe inflammation. It is sometimes seen with corneal ulcers and is a sign that the eye is in danger. Give penicillin and get medical help immediately. If the ulcer is treated correctly, the hypopyon will often clear up by itself.
The lens of the eye, behind the pupil becomes cloudy, making the pupil look gray or white when you shine a light into it. Cataracts are common in older persons but also occur rarely in babies.
If a blind person with cataracts can still tell light from dark and notice motion, surgery may let him or her see again. However, he or she will need strong glasses afterward, which will take time to get used to.
Medicines do not help cataracts. In some centers that do eye surgery, a plastic lens can be put inside the eye so that strong glasses will not be needed.
