Here, 2% xylocaine is introduced into the muscle cone behind the eyeball. The injection is usually given through the inferior fornix of the skin of the outer part of the lower lid when the eye is in primary gaze. The ciliary nerves, ciliary ganglion, oculomotor nerve and abducens nerve are anesthetized in retrobulbar block. [2]
Trabeculectomy is a surgical procedure used in the treatment of glaucoma to relieve intraocular pressure by removing part of the eye's trabecular meshwork and adjacent structures. It is the most common glaucoma surgery performed and allows drainage of aqueous humor from within the eye
Diagnosis can be further made under a slit lamp upon the observation of redundant conjunctival folds. These folds can be made more apparent by staining with fluorescein dye and by applying gentle upward pressure with a finger to the eyeball through the lower lid. In pure aqueous tear deficiency dry eye patients, fluorescein stains in the ...
incise the conjunctiva or the eyelid skin •Keratotome: small triangular blade with two sharp edges used to incise the limbus (sclerocorneal junction) •Zeigler's knife: very tiny knife for intaoccular maneuvers specially when space is less Scissors - •Conjunctival sac scissors: flat small curved scissors to cut the conjunctive •Corneal ...
The eye is a fragile organ, and requires due care before, during, and after a surgical procedure to minimize or prevent further damage. An eye surgeon is responsible for selecting the appropriate surgical procedure for the patient, and for taking the necessary safety precautions.
Living-related conjunctival limbal allograft (lr-CLAL) is a type of ocular surface stem cell transplantation (OSST) that treats limbal stem cell deficiency (LSCD). [ 1 ] lr-CLAL has been shown to stabilize the ocular surface by providing both limbal and conjunctival stem cells where prior KLAL(keratolimbal allograft) has failed.
Schematic diagram of the human eye showing. Subconjunctival injection is a type of periocular route of injection for ocular drug administration by administration of a medication either under the conjunctiva or underneath the conjunctiva lining the eyelid.
Periocular injection is an ocular route of drug administration. It is well-established route of treatment for severe uveitis and cystoid macular edema (CME) by using corticosteroids. [1] [2] Subconjunctival injection is one of periocular routes of administration.
