PURPOSE To evaluate the risk factors for pterygium in the dry, high altitude province of Ilam, Iran. METHODS The study included patients who presented to ophthalmology clinic. The patients were divided into two groups: 210 diagnosed with pterygium or pinguecula (unilateral or bilateral), and 210 healthy controls. Demographic variables, living environment, disease type, disease laterality, fam...

OBJECTIVE To compare the rate of recurrence and complications of pterygium following surgical excision by applying 0.02% mitomycin-C intraoperatively or using topical 0.02 % mitomycin-C drops postoperatively. STUDY DESIGN Randomized clinical trial. PLACE AND DURATION OF STUDY Baqai Medical University Hospital, Department of Ophthalmology, from January 2001 to July 2005. METHODOLOGY Eighty...

OBJECTIVE Pterygium is considered to be a proliferative overgrowth of bulbar conjunctiva that can induce significant astigmatism and cause visual impairment; this is the first meta-analysis to investigate the pooled prevalence and risk factors for pterygium in the global world. DESIGN A systematic review and meta-analysis of population-based studies. SETTING International. PARTICIPANTS A ...

PURPOSE To evaluate the effectiveness of amniotic membrane transplantation associated with conjunctival autograft in primary pterygium treatment. METHODS We have analyzed, prospectively, 26 patients (14 women and 12 men), from 20 to 60 years old, examined at the Evangelic Hospital Ophthalmology Outpatient Clinic. They were submitted to primary pterygium treatment with pterygium excision surge...

OBJECTIVE To compare the excision of primary pterygium by bare sclera technique and excision combined with amniotic membrane transplantation (AMT). STUDY DESIGN An experimental study. PLACE AND DURATION OF STUDY Eye Department, Military Hospital, Rawalpindi, presently known as Armed Forces Institute of Ophthalmology, Rawalpindi, from May 2007 to July 2008. METHODOLOGY A pilot study of 70 ...

AIMS The effectiveness of instillation of mitomycin C eyedrops on the recurrence rate of pterygium was assessed in patients undergoing primary pterygium surgery. Any side effects were also noted. METHODS Primary pterygia in 38 consecutive patients were surgically excised during July to December 1992. After surgery, mitomycin C 0.02% eyedrops twice daily for 5 days as well as dexamethasone 0.1...

PURPOSE To evaluate the efficacy and safety of fibrin bioadhesive in conjunctivolimbal autograft surgery for primary pterygium. METHODS Thirty-six eyes in 34 patients were reviewed with nasal primary pterygium who were treated with pterygium excision with superior conjunctivolimbal transplantation with fibrin bioadhesive. Surgical durations were recorded and the patients were followed up on t...

PURPOSE Little is known about DNA damage in human pterygium, and no data about DNA damage involvement as a potential angiogenic factor are available. We studied, with immunohistochemistry, the presence and localization of thymine dimers in the epithelial and stromal components of the human primary pterygium and its recurrences with a special emphasis on the vascular network and its interactions...

BACKGROUND To examine the immunohistochemical expression of heat shock protein 90 (Hsp90) and Ki-67 protein in human pterygium. MATERIALS AND METHODS Tissues obtained during pterygium surgery of 15 patients who underwent the bare-sclera procedure and 10 normal conjunctivae were studied. All of these pterygia were primary ones. Recurrent pterygia were excluded. Normal bulbar conjunctivas (2 x ...
