Vacularization I More Delayed in Amniotic Membrane Graft Than Conjunctival Autograft After Pterygium Exciion Original Reearch Article

Purpoe To monitor the development of graft vacularization by indocyanine green angiography (ICGA) after pterygium exciion with limbal-conjunctival autograft tranplantation (LCAT) and amniotic membrane tranplantation (AMT). Deign Randomized propective interventional cae erie. Method Anterior egment ICGA finding at one, even, and 30 day after urgery were evaluated in eye with primary pterygium treated by exciion and LCAT (14 eye of 14 patient) or AMT (13 eye of 13 patient), and the reult for graft vacularization were compared. Reult All conjunctival autograft howed early vacularization from underlying epicleral vacular bed a multiple hyperfluorecent foci at the graft margin on potoperative day 7; graft vacularization wa complete on potoperative day 30. In contrat, all graft in AMT group howed no graft vacularization at any tage after pterygium urgery. Thi delay of vacularization with AMT perited until one month after urgery. Concluion Anterior egment ICGA i ueful to monitor graft vacularization after pterygium urgery. Graft health after LCAT may be demontrated by early graft vacularization and perfuion; however, there i a delay in graft vacularization after AMT that may be related to the antiangiogenic effect of the membrane. Further tudy i needed to demontrate the relationhip between thi delay of graft perfuion and early potoperative pterygium recurrence.
