Styes
An inflammation of a gland at the base of an eyelash.
Painful but disappears after a few days with out treatment. The
use of warm compression and the use of anti-infective drops and
ointment may be prescribed to prevent the infection.
Blepharitis
he generalized inflammation of the eyelid margins, with
redness, itching and discharge. It tends to be persistent and mat
cause the eyelashes to fall out or to turn inward so they irritate
the cornea. Blepharitis is probably the single most common cause
of all eye discomfort. Blepharitis is of two types, seborrheic blepharitis
and ulcerative blepharitis. An anti-infective is required to eliminate
the eye infection and, if necessary, a topical steroid.
Microbial
Keratitis/ Corneal Ulcer
Inflammation of the cornea due to microorganisms. The
term keratitis and corneal ulcer are often used interchangeably.
It is usually regarded as more serious than conjunctivitis because
scarring of the cornea and cause blurring of vision.
Pre disposing factors:
1. Contact lens wear
2. Ocular surface disease (dry eye)
3. Corneal-anaesthesia
4. Bullous keratopathy
5. Trauma.
Corneal infection can spread through the deeper layers
of the cornea. A superficial keratitis can cause loss of sight if
it occurs in the field of vision, and a deeper keratitis can result
in blindness or loss of the eye within 24 hours of infection if
an aggressive microorganism is involved.
Patient with corneal ulcer suffer pain, blurry vision,
inability to see bright light, redness, discharge and foreign body
sensation in the eye.
Treatment for keratitis/ corneal ulcer is usually
quite aggressive. Dosing of the prescribed antibiotic is frequent,
sometimes every hour or more, especially for the first couple of
the days. Serious patients require hospitalization, and they are
always followed very closely.
Treatment can last for as long as several weeks.
Treatments used by the ophthalmologists are as per the severity
of the infection. Latest advancement for treating microbial keratitis/
corneal ulcer are fluoroquinolones.
