Purpose The aim of this study was to evaluate the clinical outcomes of surgery for recurrent pterygia using mitomycin C (MMC), double amniotic membrane transplantation (AMT), and a large conjunctival flap. Patients and methods This retrospective case series included 31 eyes in 31 patients with recurrent pterygia. All patients underwent pterygium excision, application of MMC, double AMT, and p...
PURPOSE To report and discuss cases of lamellar keratoplasty using corneas obtained during previous penetrating keratoplasty in keratoconus eyes. METHODS Corneal buttons were obtained from 7 keratoconus patients and stored in a preserving solution for 7-60 days (average, 32.4 days) before use. The recipient eyes comprised recurrent pterygium 3 eyes, primary pterygium 1 eye, pseudopterygium 1 ...
This paper will discuss the different approaches to the surgical management of pterygium, emphasizing the conjunctival autograft technique and the use of antimetabolites. HISTORICAL PERSPECTIVE Clinically, a pterygium is a wing-shaped fibrovascular growth arising from the bulbar conjunctiva onto the superficial cornea.1 It is composed of a body, which overlies the sclera, and a head, which conf...
PURPOSE To study the expression of matrix metalloprotease (MMP)-2 and MMP-9 mRNA and activities in various stages of surgically excised pterygium specimens and cultured pterygium fibroblasts and to study the effects of activation of protein kinase C (PKC) on the expression of these MMPs in pterygium fibroblasts. METHODS MMP-2 and MMP-9 mRNA expression and activities in 15 pterygium tissues an...
BACKGROUND Anti-fibrotic, anti-VEGF (vascular endothelial growth factor) medications, or radiotherapy, as adjuvant for pterygium surgical procedure, has been suggested for reducing recurrence, but difficulties may be experienced in deciding which treatment to use. The purpose of this study was to compare the efficacies of these different adjuvants for preventing recurrence following pterygium s...
PURPOSE We previously reported that importin 13 (IPO13), a member of the importin-β family of nuclear import proteins, regulates nuclear import of the glucocorticoid receptor in airway epithelial cells, IPO13 serves as a potential marker for corneal epithelial progenitor cells, and IPO13 is associated with corneal cell proliferation. Here we investigated the role of IPO13 in the pathogenesis of...
