What is red eye? How can I heal watery red eyes?  What are the causes for red eyes? Are there means I can use to get rid of my red eyes? In this discussion, apart from focussing on causes of red eye we shall delve into symptoms of red eyes, what to do for itchy eyes, how to treat red eyes as well as preventive measures.

What causes red eyes?

Contents

Red eye concept is not confined to a single definition because there are various causes of eye redness.

1. Allergic conjunctivitis

One of the most common cause of eye redness is allergic conjunctivitis. What really causes red eyes is entry of foreign substances (allergens) into your eyes leads to irritation. As a result the conjunctiva is stimulated to release histamine (a chemical substance) to help fight off the unwanted foreign substance. Victims commonly have burning red eyes that itch and sometimes are watery.

Some of the allergens are pollen from grass, trees and some plants; moulds, strong perfumes, animal skin, smoke and certain eye drops.

2. Bacterial conjunctivitis infection – Acute form

Secondly, as opposed to allergic conjunctivitis, bacterial conjunctivitis is brought about by bacterial invasion of the conjunctiva. These bacteria get their way to the body via the sinus or the ear.

During the onset of acute bacterial conjunctivitis, bacteria such as Streptococcus pneumoniae and Pseudomonas aeruginosa cause swelling of the eyelid, and pus-like discharge of thicker, yellow-green small discharges released from one eye but may transfer to the other eye.

3. Chronic Chlamydial conjunctivitis

Now, chlamydial conjunctivitis is mainly caused by the bacteria Chlamydia trachomatis. This bacterial conjunctivitis normally affect new-born babies who are exposed to the chlamydia bacteria during natural birth. Common symptoms in new-borns include may be eye redness, swollen eyelids and watery discharge in first week after birth. How is the bacteria spread? Chlamydia trachomatis is spread through the following means:

  1. Sharing with an infected red eyes patient (make-ups, washcloths – handkerchiefs, towels, e.t.c.)
  2. Sexual contact with someone who is infected with trachoma,
  • Touching your eyes with hands after attending to an infected person

Both of the bacterial conjunctivitis are contagious especially in the US and is prevalent among people who are less than 25. It may be necessary to go for diagnosis of gonorrhoea, trachoma, syphilis and other STIs testing.

4. Dry eyes & Dry Eye Syndrome

How do dry eyes cause red eyes? Under certain conditions tear glands may produce little tears and when this occurs the eye ball is not sufficiently lubricated. This leads to inflammation and irritation of the conjunctiva because eye lids cannot open and close normally in absence of tear film. Very painful red eyes is also be a usual sign. A few conditions and factors are known to result in dry eye syndrome:

5. Hormonal changes in Menopause

Hormones stimulate tear production. However, during the menopause or pregnancy period there occurs hormonal changes that render women susceptible of dry eye syndrome.

6. Ageing

As you grow older eye lids become droopy and less effective. This proves why there are many common dry eye syndrome cases in aged people, than young. Old age contributes to ectropion is a condition where the eyelids turn outward leaving the eyes exposed. Dryness results as more evaporation occurs.

7. Environmental Factors

A combination of environmental factors (hot blowing air during sunny and windy weather) dry climate and other factors such as high altitude have an influence on drying eyes.

8. Certain Laser eye surgery and Medications

After certain types of laser eye surgery e.g. LRS – Laser Refractive Surgery and Laser-assisted in situ keratomileusis (LASIK) some patients start to show symptoms of dry eye syndrome. Eye treatments involving antihistamines, beta-blockers, and oral contraceptives may result in reduced tear production.

At critical stages, chronic dry eye develops and is inflamed, to the extent that irritation is so high that you see dry red eyes. This condition is also contributed by overusing contact lenses where normal tear flow is interfered with. Overusing contact lenses also restricts amount of oxygen supplied to the cornea.

9. Eye Injury – Surgery, Abrasion and Chemical Burns

A number of actions may lead to eye injury.

Corneal Abrasion

One, is to do with corneal abrasion. You find that minor eye scratches rubs off layers of the cornea, (the transparent cover of your eye). These injuries are commonly caused by someone poking by finger, walking into a tree branch with sharp twigs, careless removal of soft lenses and use of old contact lenses. The signs and symptoms of corneal abrasion include:

  • acute pain in the eye,
  • being uncomfortable in bright lights,
  • a foreign-body sensation,
  • too much squinting,
  • production oftears,

Corneal abrasions may result into trauma and eye dryness if it is not attended to in good time. Treatments such as topical antibiotics and non-steroidal anti-inflammatory drugs (NSAIDS) are recommended.

Chemical Burns

The second cause is chemical burns.  It could either be an acid or alkali. Alkalis are typically worse than acidic burns because they lead to an elevated pH in the eye. A mild acid burn will cause eye conjunctivitis. During diagnosis, a litmus paper is useful at verifying a pH that is within the normal range of 7.0 – 7.2.

Local anaesthetic eye drops can be used to relieve pain or an irrigation treatment with Ringer’s lactate or saline solution will be given which aims at reducing the pH of the eye. People who suffer chemical burns should desist from touching their eyes as further inflammation is likely to occur.

Cosmetic Eyelid Surgery

Another cause of eye injury is when cosmetic eyelid surgery is operated to treat an infection cause of red eye. How about the red eye? Blood capillaries relax and dilate to allow more oxygen to reach the target point in eyelid. In response, there is an inflammation. Eyelid surgery also known as Blepharoplasty that involves removal of droopy upper or lower eyelids is responsible for dry eyes.

10. Blocked tear duct

What causes watery eyes in toddlers and many infants after birth is blocked tear ducts. The occurrence of this condition could be attributed to nature of tear ducts to fail to develop well, or due to an abnormal growth of nasal bone. These structures (tear ducts) help in regulating, directing secreted tears and channelling out efficiently.

The aged and older people whose eyelids have started to sag tear more often. Why it? The eyelids no longer can hold back tears from flowing. Otherwise, you are urgently required to seek help from a professional if you start to experience the following symptoms:

  • Blurred and poor vision
  • Pain around your eyes
  • Feeling presence of foreign material inside eyes

Other Causes of Red Eyes or Redness in Eyes

Other red eye causes include:

1. Blepharitis

Simply refers to inflammation of eyelids or part of the eyelids as a result of bacteria. How can it bring about irritation and cause red eye? The region near the eyelashes have oil secretion glands. Certain conditions force the glands to get clogged. Due to this fact the eyelids close and open with difficulty.

Bacterial Blepharitis – Anterior & posterior Blepharitis

Bacterial blepharitis is caused by Staphylococcal aureus bacteria which affects the anterior/posterior part of the eyelid. Symptoms include burning a foreign body sensation, eyelashes may also get removed.

Apart from the very common symptoms namely – watery eyes, red eyes, swollen and red eyelids other signs are:

  • Itching eyelids,
  • Formation of crusts on the eyelids – evident in the morning after sleep,
  • Greasy eyelids,
  • Blinking too often,
  • Light sensitivity,
  • Irregular/abnormal growth of eyelashes,
  • Eyelash loss or broken eyelashes.

Blepharitis may be complicated if what cause red eyes in anterior blepharitis is linked to demodex (microscopic harmless mites). Posterior blepharitis occurs due to a problem with the Meibomian glands, found on the inside edge of eyelids. Either excessive oil is produced or a blockage of oil ducts that cause irritation. The blocking is said to be due to a skin condition called rosacea whereas seborrhoeic dermatitis may be associated with excessive oil.

Your doctor can prescribe drugs for bacterial blepharitis or you may use topical antibiotics medicine available over the counter.

2. Herpes Simplex Virus Type 1

Herpes simplex virus Type 1 can cause eye infections. For instance, patients who are living with HIV have a weakened immune system and this provides a favourable internal environment for HSV-1.

Symptoms include redness of the eye cornea, eye ache or pain, difficulty when opening the eyes in bright light (photophobia), watering of the eye and blurry vision. These signs usually appear during the secondary infection. However, there may never be observable signs during the primary infection.

Treatment for viral conjunctivitis due to HSV-1 is applying antiviral eye ointment such as Aciclovir ointment or Ganciclovir gel will be used to stop the virus from spreading. Note the viruses do not get killed but are stopped from multiplying further until the infection goes away.

3. Corneal Herpes or Ocular Herpes?

Eye infection caused by the herpes simplex virus (HSV-1) type 1 may lead to partial vision problems if the virus spreads deep into the cornea. You should be careful to see signs and symptoms. When you start to have much sensitivity to light, eye redness, swollen eyes, eye pains or watery discharge, see your doctor immediately for diagnosis and test.

4. Non-allergic Bloodshot Red Eye

Did you wake up one morning and found out blood red eyes? Red bloodshot eyes is a condition where the blood vessels beneath the white eye swell, expand and redden. Why? It is because of the small dust particles, or other similar material present in one eye or both.

5. Red Eye Contacts – Overused contact lens

You are most likely to have red eyes if you exceed the exact time meant for your soft eye lenses. Wearing your contact lenses for longer than the recommended period can cause irritation and discomfort. Never extend the specified period of contact lens use. Ensure you discard them and get new package.

6. Poor Hygiene of Contact lens & Bacterial Keratitis

Extra care is needed for the contact lens users. If your contact lenses are not cleaned, and rinsed using disinfecting solutions, the biggest risk is accumulation of microbes which definitely end up in the eyes. Further on, bacterial keratitis – red eyes disease – develops because of recurring infections. As a cautionary action immediately see an ophthalmologist doctor to remove your contact lenses.

7. Cold and flu

What causes watery eyes in the morning is mainly cold and flu. Eye redness, sneezing and coughing are red eye symptoms of cold and flu. Use of herbal products and natural fruits helps to fight germs and reduce symptoms. You can swallow Beechams all in one tablets, strepsils and syrups to reduce fever, headache and coughing. Avoid areas with congestions and large crowds so as to prevent catching it.

8. Conjunctival Haemorrhage

In certain rare situations your eyes may turn red in that a blood vessel bursts beneath the sclera without your conscience thus not easy to realise. In most cases this is a condition that does not require any treatments.

Red Eye Diagnosis – Differential Diagnosis

What are some of the diagnosis procedures of red eyes? Where is differential diagnosis applied?

Bacterial Conjunctivitis

First, Conjunctival scrapings are commonly used in diagnosis of bacterial conjunctivitis where Gram stain is useful for identifying bacterial characteristics. These conjunctival scrapings are acquired by using special tools during the process of diagnosing the species of bacteria that cause it. Giemsa stain is applied in screening and studying causes of red eye bodies of Chlamydia.

Chlamydial Conjunctivitis – Diagnosis

Cultures can be completed for chlamydial conjunctivitis diagnosis, and other bacterial infections as well as for viral agents. However, cultures are not necessary except for the case of known fungal contamination of a contact lens solution or a corneal ulcer.

How does viral diagnosis differ from bacterial tests? The cellular response in conjunctivitis differs according to the cause, for example after differential diagnosis of viral infections the lymphocytes are found out to be predominant.

Dry Eye Diagnosis

During diagnosis of dry eye the following techniques may be used.

Volume measure tears – In carrying out this diagnosis the Schirmer test is put into practical use. A blotting paper strip is placed under lower dry eye patient eyelids where measurements are taken from.

Tears quality. Your doctor checks out for corneal eye condition using test eye drops in order to detect any unusual changes.

Red eye history examination. Overall health of your eye health can help your doctor diagnose the cause of your dry eyes.

How is Herpes Simplex Eye infection diagnosed?

Since the cornea is transparent, a doctor easily uses clinical stain and views it under a magnifier. In case the doctor notices a small ulcer erosion on the cornea urgently visit an eye specialist (ophthalmologist).

Red eye effect or Natural Red Eyes?

Didn’t you know red eye effect is a phenomenon in photography? It produces really red eyes especially the pupil. Occasionally it happens when there is live performance on stage while flashes of camera operators come too close to eyes now and then. Have a glance at red eye effect pictures captured below.

What are some of the preventive strategies I can use at home? How do I prevent viral conjunctivitis?

Like any other contagious infections it is important to prevent transmission of viral conjunctivitis to get control of it. By ensuring that both patient and care provider wash hands thoroughly and avoid touching the infected eye. In addition avoid sharing towels, linens, and other cosmetics. Patients who have been infected with pink eye disease are advised to stay away from school and work until it is well contained.

Eye Contacts, Hygiene, Handling & Care
