BACKGROUND The purpose of this study was to evaluate the outcome of pterygium excision with inferior conjunctival autografting for primary pterygium. METHODS This was a prospective noncomparative interventional case series study enrolling 50 eyes of 50 patients with primary pterygium between November 1, 2010 and October 30, 2011. All patients underwent the standard surgical technique for pter...

OBJECTIVE The present study aimed to evaluate the association between smoking and incident pterygium in adult Korean men. DESIGN A retrospective nationwide longitudinal cohort. SETTING National Health Insurance database of South Korea. PARTICIPANTS This study included Korean men (age range: 40-79 years) registered in the Korea National Health Insurance Service database from 2002 through 2...

PURPOSE To investigate human beta-defensins (HBDs) and cathelicidin LL-37 (LL-37) expressions in patients with pterygium. METHODS In this retrospective consecutive case series, 26 pterygium specimens and 15 normal conjunctival specimens of 15 control subjects were in vestigated. Expressions of HBD-1, HBD-2, HBD-3, and LL-37 were assessed using immuno histochemical staining. A brown color in t...

Objective: To determine the difference in mean corneal curvatures before and after pterygium excision, by using automated refraction and keratometry. Methodology: This quasi-experimental study was conducted at Eye Unit-I, Bahawal Victoria Hospital, Bahawalpur, from March 2010 to August 2010. Thirty patients with primary pterygium were analyzed before and after pterygium surgery for corneal curv...

Pterygium is characterized by the thickening of the bulbar conjunctiva and the invasion of the cornea from the sclerocorneal limbus to the central portion of the cornea. Pterygium produces corneal deformation, which extends toward the central portion of the cornea. The visual disorders depend on the corneal extent. The treatment goal is the removal of the corneal and conjunctival portion of the...

Background Pterygium is a common degenerative eye disease. Despite various surgical methods to treat pterygium, recurrence is the main complication. The main issue is finding a surgical method with the lowest recurrence. Objective to compare the complications, recurrence rate and the cosmetic effects of two surgical techniques, namely conjunctival rotation autograft (CRA) and conjunctival aut...

Cannabinoids, as multi‑target mediators, activate cannabinoid receptors and transient receptor potential vanilloid (TRPV) channels. There is evidence to support a functional interaction of cannabinoid receptors and TRPV channels when they are coexpressed. Human conjunctiva demonstrates widespread cannabinoid receptor type 1 (CB1), CB2 and TRPV channel localization. The aim of the present study ...

Pterygium is a fibrovascular lesion of the ocular surface that can display an aggressive clinical behavior and, occasionally, threaten vision. Although there is no consensus on its pathogenesis, recent evidence suggests that it is a proliferative, rather than degenerative condition strongly correlated with exposure to ultraviolet radiation (UVR) of solar light. Molecular genetic alterations rep...

OBJECTIVE/METHOD The purpose of the study is to evaluate those cases of pterygium surgery with fibrin sealant that produced dehiscence of the graft, and then apply and evaluate the efficacy of a different surgical technique in an attempt eliminate this complication in previously identified cases of high risk. The first phase is a retrospective study of 42 cases of pterygium surgery. In the seco...
