Laser conjunctivoplasty: A new technique for correction of mild medial ectropion

Abstract

Thirty patients with mild medial ectropion of the lower lid were treated by Argon green laser. A diamond-shaped area (6 x 4 mm in size) on the medial part of the tarsal conjunctiva of the lower lid was burnt with overlapping spots until white blanching and visible contraction of tissue were seen. The apex of the diamond was kept 4 mm below the punctal opening. After an average follow-up of 6 months, functional success was achieved in 22/30 eyes. Anatomical success in terms of repositioning of the punctum was attained in 24/30 eyes. The only side effect noted was a mild burning sensation of the eyes lasting for two hours after the procedure. This is the authors' initial experience with a somewhat new and easy procedure to treat mild medial ectropion of the lower lid that can be performed on an outpatient basis.

Treatment outcomes of modified argon laser photocoagulation for conjunctivochalasis

“…[ 21 ] Furthermore, a study on medial ectropion repair using palpebral laser conjunctivoplasty indicated that laser-induced conjunctival shrinkage is safe since it does not induce excessive conjunctival burns or scarring. [ 22 ]…”

“…[21] Furthermore, a study on medial ectropion repair using palpebral laser conjunctivoplasty indicated that laser-induced conjunctival shrinkage is safe since it does not induce excessive conjunctival burns or scarring. [22] Conjunctival shrinkage may reduce its redundancy, and conjunctival coagulation may reinforcement the conjunctival attachment to the globe, reducing conjunctival laxity. [23] The photothermal mechanism underlying CCh shrinkage induced by the argon laser is similar to that of a thermal cautery device or high-frequency radiowaves.…”

ImageJ assessment of double-frequency YAG laser efficacy in treatment of mild lower eyelid ectropion with punctal eversion

“…To our knowledge, using of argon laser without excision of tissue, or the use of full-thickness everting sutures has been described only at 2003 by Nainiwal S, and co-authors [ 17 ] and achieved good functional results by relief of symptoms in 22 (73%) eyes, and an acceptable anatomical outcome with repositioning of the punctum in 24 (80%) eyes.…”

Near-infrared laser thermal conjunctivoplasty

“…Argon lasers have been used for laser conjunctivoplasty 12,13 . However, they work at a wavelength of 532 nm and the laser energy is primarily absorbed by blood and can lead to vessel rupture and hemorrhage.…”
