ABSTRACT

@#AIM: To observe the clinical efficacy of limbal-conjunctival autograft transplant(LCAT)for double-head pterygium.<p>METHODS: Prospective case study. Totally 46 patients(54 eyes)diagnosed with double-head pterygium collected in PLA 474 Hospital from January 2014 to July 2015, including 8 patients(16 eyes)with binocular double-head pterygium, 11 patients(11 eyes)with monocular double-head pterygium and the other eye with nasal side pterygium, pterygiun eyes only included as study subject, and 27 patients(27 eyes)with monocular double-head pterygium. The eyes with double-head pterygium underwent pterygium resection and autologous corneal limbal stem cell transplantation, nasal conjunctival flap was gotten from the superior bulbar conjunctiva of affected eye, and temporal conjunctival flap was gotten from the inferior bulbar conjunctiva of other eye. Follow-up the patients on 1d, 7d, 1mo and 1a after operation to complete the vision and slit lamps to observe the complications and pterygium recurrence.<p>RESULTS: Forty-four patients(52 eyes)completed the follow-up of 1a, while 2 patients(2 eyes)were lost. Three patients(3 eyes)developed recurrence, and the recurrence rate was 6%. Two eyes with nasal side pterygium developed recurrence and 1 eye with temporal side pterygium developed recurrence, while there was no complication observed.<p>CONCLUSION: Nasal conjunctival flap was gotten from the superior bulbar conjunctiva of affected eye, and temporal conjunctival flap was gotten from the inferior bulbar conjunctiva of other eye for double-head pterygium had good clinical effect and low recurrence rate, which provide a better way to treat double-head pterygium.
