Disorders in the conjunctiva may lead to:

● Red Eye

● Conjunctivitis

● Pinguecula

● Pterygium

 

red eye

noun. an eye that appears red due to illness or injury

Redness in the eye can be caused by many conditions and injuries that can lead to irritation, blood in the eye, or swelling of blood vessels.

 

It is usually injection and prominence of the superficial blood vessels of the conjunctiva, which may be caused by disorders of these or adjacent structures. Conjunctivitis and subconjunctival hemorrhage are two of the less serious but more common causes.

conjunctivitis

noun. a swelling and irritation of the membrane that covers the white part of the eye and eyelid lining

It is often referred to as “pink eye” due to the pink color of inflamed blood vessels. Many irritants can cause temporary conjunctivitis. Seasonal or indoor allergens, pollutants in the air, eye makeup, contact lenses, or other kinds of debris may cause irritation and inflammation. It is usually alleviated when debris or allergens are no longer present. Washing the affected eye and keeping it clean often allows enough time to heal, and symptoms should subside.

Infection conjunctivitis may be viral or bacterial. The viral type may accompany a cold, fever, sore throat, or flu. Eye redness and watery discharge are common symptoms. Staph or strep bacteria may cause bacterial conjunctivitis. It can include eye redness and discharging mucus.

Bacterial and viral pinkeye can be highly contagious and can easily be passed between people. This is often seen in children as they can contract it during play in schools or daycares. The symptoms are generally mild and do not pose a serious threat to eye health. However, it should be treated by an eye doctor. A doctor should also see newborns with symptoms as it’s important to diagnose and treat symptoms in young babies to ensure no vision loss occurs.

Conjunctivitis is a common condition we see often. Some eye diseases are similar, so it’s important for patients to have a professional evaluation by an eye doctor to determine their specific needs and proper treatment. Treatment is different depending on the cause, but all forms of conjunctivitis need professional evaluation to ensure good eye health. In most cases, it can be successfully treated with antibiotics, eye drops, or ointments.  

pinguecula

noun. a yellowish, raised growth on the conjunctiva. It’s usually on the side of the eye near your nose, but can happen on the other side too. A pinguecula is a deposit of protein, fat, or calcium.

pterygium

noun. a growth of fleshy tissue (has blood vessels) that may start as a pinguecula. It can remain small or grow large enough to cover part of the cornea. When this happens, it can affect your vision.

lf you have had a pinguecula or a pterygium at least once before, try to avoid the things that cause these growths. Here are some ways:

  • wear sunglasses to protect your eyes from ultraviolet (UV) light

  • protect your eyes from dust by wearing glasses or goggles

Symptoms of pinguecula and pterygium can range from mild to severe. They include:

  • redness and swelling of the conjunctiva, mostly while the pterygium grows

  • a yellow spot or bump on the white of your eye

  • dry, itchy, burning eyes. Or feeling like sand or grit is stuck in your eye

  • blurry vision
