Background: A pterygium is a fleshy, wing-shaped growth from the conjunctiva, crossing over limbus onto cornea. The tissue fibrovascular and can occur nasal or temporal It be bilateral process asymmetric with one eye affected by larger than other. Objectives: To compare between Subconjunctival injection of bevacizumab (Avastin) conjunctival autograft in treatment primary pterygium. Patients Met...

Purpose: Pterygium is a benign growth of conjunctival tissue frequently related to chronic sunlight exposure and hot and dry climate. Purpose of this study was to prospectively analyze the most common pterygium symptoms and risk factors leading to the decision for surgical removal. Methods: 40 patients (27 males, 13 females), mean age 48.75 years old (SD 8.5), with primary pterygium and no othe...

PURPOSE To assess matrix metalloproteinase (MMP)-9 expression in pterygium lesion. METHODS A prospective randomized clinical trial was done to evaluate the expression of matrix metalloproteinase in normal and in primary or recurrent pterygia in Tenon's capsule by immunohistochemical analysis and a computerized image analysis system. The data were submitted to statistical analysis. RESULTS M...

Purpose. To investigate changes of dry eye test results in patients who underwent pterygium surgery. Methods. Seventy-four patients who underwent primary pterygium surgery were enrolled in this study. At the baseline, 3-, 12-, and 18-month visits, measurements of tear osmolarity, BUT, and Schirmer test were performed. The patients were divided into 2 groups: Group 1, which consisted of patients...

Aims—To compare the rate of recurrence and complication after surgery for primary pterygium performed by one surgeon using either intraoperative mitomycin C or â irradiation. Methods—A retrospective study was performed of 164 eyes in 164 patients who had undergone primary pterygium surgery. After the pterygium was excised, the bare sclera was covered by sliding adjacent superior conjunctiva. 10...

The expression of growth factors in ophthalmic pterygium and phenotypically normal conjunctiva was examined and correlated with the clinical findings. Fifteen specimens of ophthalmic pterygia and 8 specimens of phenotypically normal conjunctiva were examined. Total RNA was extracted from all specimens and mRNA levels for transforming growth factor (TGFB1), vascular endothelial growth factor (VE...

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...

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...

Purpose: The purpose of this study is to reflect anterior segment specialists’ current practice pattern regarding the management primary pterygium. Methods: A 24-item survey indications for surgery, different surgical techniques, use adjuvant pharmacological therapy, type intraoperative and postoperative preferred treatment early recurrences was sent members Saudi Ophthalmological Society (SOS)...

–Pterygium is a fibrovascular proliferation of conjunctiva onto the cornea which leads to considerable visual impairment due to corneal astigmatism. Surgical excision is the only treatment; however recurrence continues to be a complication. Therefore, ant metabolites like Mitomycin C & 5Fluorouracil have been used as chemoadjuvant to reduce it. Present study was carried out to evaluate the effi...
