Corneal Burns
Treatment with MEBO
Therapy with MEBO to treat thermal corneal burns is more advantageous
than traditional therapy, lessen the healing time obviously.
MEBO can
higher the post-healing vision and decrease the corneal complications.
The corneal
thermal burns can divide into the flame burns and the
contact burns, which latter refers to the boiling water, boiling oil,
the scalding ashes and so on.
The corneal thermal burns often complied
with burns on face and four limbs, while treatment, the corneal thermal
burns are often neglected that delay the treatment opportunity and
increase the pain for the patient.
Therefore, pay attention to the
treatment of corneal thermal burns have extremely significance.
Treatment: 26 cases with 46 eyes of corneal thermal burns in the
treatment group applied MEBO locallly, qid, expose without wrapping,
and promptly cleaned up when eye secretion increased. 22 cases with 40
eyes of corneal thermal burns applied 0.25% chloromycetin eye drops,1~2
drops every time, qid to q4h,and applied erythromycin eye ointment
before sleeping. The severe corneal thermal burns of the entire group
applied 1% atropine eye drops to dilate the pupil, 1 drop every time,
qd to qid.
Those who complied with burns on the face and so on, follow
the MEBT/MEBO therapy, and, on the base of total injury condition,
applied high protein, high energy and high vitamin support, as long as
proper antibiotic prophylaxis.
Discussion
Corneal thermal burns is a very common type of
burns, neglect or
improper treatment of corneal thermal burns can easily result in
corneal permanent scars, such as corneal nebula, keratoleukoma,
severely might result in corneal ulceration or perforation, and lead to
atretoblepharia, granulation, adherent leucoma or staphyloma that
result in permanent vision damage and blindness.
In this article,
through observed the treatment of 48 cases with 86 eyes corneal thermal
burns, the mild burns were generally completely recovered in 1 to 2
days.
The average
healing time of moderate and severe burns in
treatment group that applied MEBO are apparently shorter than
traditional therapy and have obvious difference between two groups
(P<0.05).
Besides, MEBO therapy obviously relieved the
subjective
feeling and elevated healed vision in certain degree, and alleviated
corneal complications.
There are
some characteristics in applying MEBO in corneal thermal
burns:
Cornea is
invascular tissue, 15% of its nutrition comes from limbus
blood vessels network, 5% relies on aqueous humor diffusion, 80%
acquired from direct exchange with the air.
After corneal
burns, limbus blood vessels network was damaged, limited
the supplement of nutrition, and affected the repair and regeneration
of cornea.
After burned,
vasculization causes corneal pannus and leads to long
term keratitis. MEBO consists of various nutrients, such as
polysaccharide, lipid, protein, etc., and the plenty glucose can supply
the insufficient energy of burned corneal lesion, vitamin and organic
acid can directly involve the topical nutrition support, maintain
respiratory metabolism, protein and enzymes involve in cell growth and
differentiation and enhance the corneal epithelium repair.
MEBO can smooth the drainage and substitute the topical metabolic
dysfunction that caused by injury. MEBO matrix ingredients can absorb
the metabolite of corneal lesion and can carry them to the surface of
the ointment, at the same time, the nutrients of MEBO continuous
diffuse on the corneal lesion, supply the ingredients that corneal
lesion repair need, accelerate the repair of injured cornea and shorten
the healing time.
Corneal
thermal burns, especially moderate and severe burns, all
involved corneal epithelium and Bowman’s membrane, even the
stroma. General concepts of these corneal structures will be granulated
by connective tissue and formed permanent scars after injured.
MEBO
consists of vitamin and organic acid that related to the granulation of
connective tissue. They can reduce the proliferation of opaque fibers,
avoid escharation, and maintain the corneal transparency and visual
function.
The cornea is abundant in trigeminal nerve terminals with sensitive
sensation.
After corneal thermal burns, the corneal algogenic nerve
terminals injured or caused blood supply insufficiency or anoxemia that
lead to obvious pain and subjective irritation.
MEBO can
clear away the
heat and can disintoxicate, invigorates the blood to remove extraverted
blood, and improve local microcirculation, recovers limbus midterm
tissue, alleviates or relieves the pain.
MEBO consists of endolipid of golden cypress that can sterilize and can
be antalgesic and directly
relieve the pain from the injured eye.
