Abstract

Red eyes are a very common problem seen in the ophthalmology department. The causes of this common symptom are several and management protocols vary depending on the doctor. This article has been written to help shed light on the most serious as well as the most commonly seen causes of red eye with a list of over-the-counter medications which may help you find a cure.

A Simple Approach to Cure Red Eyes

Red eyes are a very common problem seen in ophthalmology day in and out. The causes of this common symptom are several. The management of red eye always presents a challenge to even the most experienced ophthalmologist due to the sheer number of causes and associated overlapping causative factors.

The most important symptoms to watch for are:

Given below are a few common causes of red eyes listed as per the "Sticky-Itchy-Dry" algorithm:

1. Viral conjunctivitis

This condition is more aptly called epidemic conjunctivitis, caused by strains of adenovirus. The condition is highly contagious and spreads from one person to another by contact with tears or nasal discharge of the patient. The common belief that it spreads by looking into a patient's eye is a myth. The infection in severe cases may cause ulcers on the cornea and can lead to corneal scarring which can decrease your visual acuity.

The main symptom is 'sticky eyelids on waking up from sleep'.

There are no treatments which are available to target the viruses and the current guidelines prohibit the use of antiviral ointments for treatment of conjunctivitis. This is a severe handicap to the ophthalmologist who has to haplessly wait for the patient's own immunity to save him, unable to start antivirals until the cornea has ulcerated.

The treatments usually prescribed are:

a) Lubricant eyedrops (over the counter) - Carboxymethylcellulose acetate 0.5 and 1 %, Carmellose 0.5 %, Hypromellose 0.5 %, Polyethylene glycol and Propylene glycol.

b) Antibiotics - Moxifloxacin eyedrops 0.5 % and Tobramycin eyedrops 0.3 %, antibiotics are also available in the ointment form for longer action.

2. Allergic conjunctivitis

It is a very common cause of red eyes, mostly in young children aged less than 10 years. A multitude of allergens (dust mite, pollen, temperature change, food items) can be the causative factors.

The main symptom is 'itching'.

The treatment principle in all the cases is to suppress the body's immune reaction in the allergy. These allergic responses are usually present throughout life, being most potent during childhood and will wane in intensity as children near adolescence, but will not stop completely.

A few of the commonly prescribed treatment modalities are:

a) Antihistamines and decongestants - Olopatadine 0.1 %/0.2 %, Naphazoline, Epinastine, Chlorpheniramine maleate.

b) Lubricant eyedrops - lubricant eyedrops (over the counter) - Carboxymethylcellulose acetate 0.5 and 1 %, Carmellose 0.5 %, Hypromellose 0.5 %, Polyethylene glycol and Propylene glycol.

c) Steroids - Loteprednol 0.5 %, Difluprednate, Dexamethasone, Prednisolone.

d) Immune modulators - Cyclosporine.

e) NSAIDS - Flurbiprofen, Nepafenac, Bromfenac.

3. Dry eyes

This is the ubiquitous red eye seen in IT and accounting professionals.

Most common symptoms include 'dryness or a burning sensation'.

Treatment options:

a) Lubricant eyedrops (over the counter) - Carboxymethylcellulose acetate 0.5 and 1 %, Carmellose 0.5 %, Hypromellose 0.5 %, Polyethylene glycol and Propylene glycol.

b) Blinking more frequently.

4. Acute congestive glaucoma

This is a serious buildup of pressure inside the eye which can permanently impair vision within a few hours. The disease is classified as an ophthalmic emergency and needs specialist ophthalmologist consultation.

This condition is seen in females, dark-skinned races, people having a family history of glaucoma, and hypertensives. The major risk factor is age and 2 % of all the world's population over 40 are at risk.

The symptoms are 'overwhelming pain', vomiting, headache, blurred or foggy vision, seeing colored rings around the light. Once such symptoms start, it is very important to rush the patient to the emergency department.

Treatment of this disorder is by medication and laser.

5. Acute anterior uveitis

This is also a very painful disorder although not as sudden and dramatic as acute congestive glaucoma. This condition is seen in young and middle-aged individuals. The disorder is nothing but an auto-destruction of our body by our own immune system. The reaction can be severe in young individuals and can lead to the destruction of the internal structures of the eye and permanent blindness.

The condition presents with 'severe pain and redness', some patients may have recurrent attacks of this disorder over their lifetime. These patients need ophthalmologist consultation.

The treatment involves immunosuppressants and recurrent cases will need blood tests also.

6. Subconjunctival and periorbital hemorrhage

These are blood clots around the eyeball. Subconjunctival hemorrhage is a benign condition and will disappear if left on its own. The problem is that, to the untrained eye, it looks similar to periorbital hemorrhage, which is a vision-threatening disorder.

Hence, even these two disorders are best sorted out by seeing the doctor. As an immediate measure, ice cubes may be applied over the closed eyelids. Doing this helps the blood clot dissolve faster.

Take Home Points

The causes of red eye are numerous, each with its own characteristic symptoms "Sticky-Itchy-Dry".

You must see a doctor in case you are not able to see clearly, have severe pain or have symptoms which are getting worse.
