BACKGROUND/AIMS Bare sclera resection with and without use of mitomycin C and conjunctival autograft placement are three surgical techniques currently in use for the treatment of primary pterygium. The purpose of this study was to determine through a meta-analysis the risk for postoperative pterygium recurrence comparing the three surgical treatment modalities. METHODS A search through Medlin...

OBJECTIVE To evaluate the safety, efficacy, and recurrence of pterygium following 90 degrees versus zero degrees and 180 degrees rotation autograft for treating primary pterygium. METHODS We included in this observational, prospective, and comparative study, 74 patients (47 males, 27 females) with advanced primary pterygium, with a mean age of 47.5 years (range 19-79 years). This study was co...

This study was aimed to assess the predictability of intraocular lens (IOL) power calculation after simultaneous pterygium excision and phacoemulsification with IOL implantation. We retrospectively reviewed the clinical charts of 60 eyes of 60 consecutive patients (mean age ± standard deviation, 73.5 ± 7.0 years) who developed pterygium and cataract. We determined visual acuity (logMAR), manife...

The angiotensin II (Ang II) is the principal effector peptide of the RAS system. It has a pleiotropic effect and, beside its physiological role, it has the property to stimulate angiogenesis and activate multiple signalling pathways related to cell proliferation. The purpose of the study was to determinate the Ang II expression and localization in Sardinian pterygium and normal conjunctiva by i...

Pterygium is a chronic eye disease: among its recognized risk factors there is long-term exposure to ultraviolet (UV) radiation. The Sun is the main source of UV exposure: according to the World Health Organization, the Population Attributable Fraction of pterygium due to solar radiation (SR) is 42-74%. Outdoor work can deeply influence the eye exposure to solar UV rays, but, despite this, pter...

Vascular growth factors such as vascular endothelial growth factor (VEGF) have been detected in pterygium [12-15].There is marked elevation of VEGF in pterygia in comparison to normal conjunctival samples [12-15]. Although the pathogenesis of pterygia is still poorly understood, their formation and progression are known to depend on neovascularization. It has been postulated that the developmen...

Of various techniques of pteryium surgeries to prevent recurrence, conjunctival limbal auto graft has been the most successful adjuvant since studies have shown role stem cell deficiency (LSCD) as pathology pterygium. The common method auto-graft fixation post pterygium excision is suturing; with drawbacks prolonged operating time and postoperative discomfort. Replacing sutures tissue adhesives...

AIM To assess the effect of topical bevacizumab use on postoperative pterygium recurrence in eyes who underwent pterygium excision with limbal-conjunctival autograft transplantation (LCAT). METHODS Eighty-eight eyes of 88 patients with primary pterygium were included. Pterygia were graded preoperatively from type 1 to type 3 (type 1 atrophic, type 3 inflamed) according to the inflammatory sta...

BACKGROUND Pterygium is a common ocular disease. Outcomes ofpterygium surgery are variable. OBJECTIVE To evaluate the results ofpterygium excision, particularly the recurrence rate and complications of surgery. MATERIAL AND METHOD Patient data who had pterygium excision at Thammasat Hospital from October 2010 to September 2013 were reviewed. Age, sex, primary or secondary pterygium, methods...

OBJECTIVE To investigate the changes induced by a pterygium or its surgical removal on the biomechanical properties of the cornea and to determine factors that might affect these parameters. METHODS This prospective pilot interventional, non-randomized, observer-masked study included 20 eyes of 20 patients with a unilateral primary pterygium (pterygium group) and 19 fellow healthy eyes (contr...
