Pterygium is known to affect refractive astigmatism, which can have a significant impact on vision. This study was undertaken to evaluate the effect of pterygium excision on refractive astigmatism. Thirty-six eyes with primary pterygium with astigmatism of 2D or more were analysed before and after pterygium excision. Astigmatism increased with the increase in the grade of pterygium (P = 0.00000...

This study determined the clinical effect of subconjunctival administration of bevacizumab in patients with primary and recurrent pterygium. The study was an off-label, single-dosing, interventional case series involving 22 patients with primary and recurrent pterygium. They received subconjunctival bevacizumab (0.2 cc). Pterygium vascularity and thickness was graded. The size of the pterygium ...

Objective: To determine and compare the mast cell count in primary and recurrent vascularized pterygium, and in normal bulbar conjunctiva. Methods: The study included 22 patients with primary pterygium (PP group) and 28 patients with vascularized recurrent pterygium (VRP group) that underwent excision via the limbal conjunctival autograft technique. Normal conjunctiva samples were collected fro...

BACKGROUND Pterygium is a disorder of the ocular surface induced by chronic exposure to UV-light. Abundant data is available from patients with primary pterygium, but scarce from those with recurrent pterygium. The present study aimed to explore the oxidant/antioxidant status in tissue of primary and recurrent pterigium in men and women. METHODS Pathological tissue samples were taken during s...

The purpose of this study was to compare the inhibitory effect of bevacizumab on human Tenon's fibroblasts (HTFs) cultured from primary and recurrent pterygium. Cultured HTFs were exposed to 2.0, 5.0, 7.5, and 15.0 mg/mL concentration of bevacizumab for 24 hours. The 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyl tetrazolium bromide and lactate dehydrogenase leakage assays were then performed to ass...

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 ...

Recurrence of pterygium is the main concern for ophthalmic surgeons after the excision of pterygium. To evaluate the efficacy and safety of ethanol treatment during pterygium excision in preventing the recurrence of pterygia. A prospective randomized study was performed of 78 eyes in primary pterygium patients treated by excision. Primary pterygium patients were randomly assigned to ethanol gro...

Material and Method: There were 120 cases aged between 30-60 years of both genders. Included patients had primary Pterygium encroaching cornea up to 2 mm from limbus. Patients with Pseudopterygium, recurrent Pterygium and active ocular infection were excluded. All the selected patients underwent limbal stem cell autograft technique for pterygium treatment and recurrence was noted after 6 months...

purpose: to present an extraocular muscle disinsertion in a pterygium surgery case report: a 61-year-old woman presenting an acute diplophia after a nasal pterygium surgery. the medical rectus muscle was cut during the primary surgery which was immediately reported and the muscle was reinserted to its original site and recovery was more or less obtained. conclusion: anatomical consideration met...

I enjoyed reading the article by Malik et al titled ‘Efficacy of sutureless and glue-free limbal conjunctival auto-graft for primary pterygium surgery’ published in the Nepalese Journal of Ophthalmology (Malik et al, 2012). The authors highlighted an important technique of primary pterygium surgery without application of sutures or bio-fibrin glue. This is, of course, a very challenging procedu...
