Eye allergies and infections- spot on diagnosis and treatment
Eye allergies and infections is a condition of invasion of microbes which interfere with the normal functioning of eye. The symptoms include foreign body sensation, photophobia, itching, redness and lacrimation and pain in the associated area.
The diseases and allergies of cornea, conjunctiva, eyelid and sclera can be the result of bacterial, viral, fungal, protozoa and algal attack. It can also be due to entry of foreign particle into the eye.
Chances of astigmatism
The particles when enter the eye can also damage the natural tear film. These particles or microbes cause irritation to the eye due to which they a person rubs the eye very frequently although there are no signs of redness. This frequent rubbing can damage the curvature of the cornea and can cause astigmatism.
Why do we need spot on treatment
In any type of disease or condition of the body (acute or chronic; mild or severe) the spot on diagnosis and treatment plays a key role in the prevention of spread of disease.
Huge demand of qualitative clinical practice
We need best of clinicians in the field of ophthalmology who have command over diagnosis. This helps in prescribing medications. The diseases spread by bacteria are of various types. The diversity in pathologically active bacteria is very large. This means that there must be variety of anti-biotic as per requirement of certain type of ocular infection.
How to do spot on diagnosis and treatment
The best way of prescribing any medicine for eye allergies and infections depends upon the following factors
- Site of infection and local susceptibility pattern
- Age, hepatic and renal functions of the patient
- Previous history of the disease
- History about allergies to certain drugs
Sometimes to achieve prompt treatment of mixed infections, the physician prescribes combination therapy of anti-microbial drugs.
This is a crucial step as the clinician should be very obvious about the diagnosis as if clinicians fail to do specific diagnosis, the patients can develop adverse effect and resistance to certain drugs.
Classes of bacteria
The most common classes of bacteria which cause a variety of diseases are gram positive cocci, gram positive rods, gram negative cocci and gram negative rods.
Eye allergies and infections
The diseases caused by them and other microbes are allergic conjunctivitis, Dacryocystitis, interstitial keratitis, chalazion, blepharitis, meibomitis, episcleritis, sclerites, herpes zoster keratitis, ocular tuberculosis, dendritic keratitis, mycobacterial infections of the eye, uveitis etc.
Prescribing medicines
The list goes on and hence the anti-biotic must be prescribed by considering their scope and mode of action. For all the mild infections and allergies it is not necessary to give bactericidal antibiotics because the bacteria can develop resistance to their strong bactericidal effect.
Prescribing painkillers
The diseases of the eye can cause pain. Hence analgesics along with anti-microbial drugs are also prescribed to relieve pain and treat infection.
What we actually want
It is necessary to give correct and spot on diagnosis along with prescribing best of medicines by considering their contra-indications as well. The purpose of giving drug is to treat the infection or allergy of eye without letting microbe to develop resistance against the drug.
