Prevalence and clinicopathologic findings of conjunctival epithelial neoplasia in pterygia.

Purpose: To study the prevalence of conjunctival neoplasia in clinically diagnosed pterygia and the clinicopathologic characteristics of conjunctival tissues obtained from pterygium excision.

Design: Prospective, observational case series.

Participants: From February through August 2007, consecutive subjects indicated for pterygium excision were enrolled from an outpatient eye clinic of King Chulalongkorn Memorial Hospital, Bangkok, Thailand, and from the eye camp at the 6th Station of the Thai Red Cross Society, Aranyaprathet District, Sa Kaeo, Thailand.

Combined deep topical and superior subconjunctival anesthesia for extracapsular cataract extraction in a rural eye camp.

Background: Anesthesia for cataract surgery at eye camps needs to be simple, safe, and effective.

Methods: We prospectively studied 98 patients undergoing cataract extraction in a rural eye camp in Thailand. Patients undergoing extracapsular cataract extraction with intraocular lens implantation (ECCE/IOL) received deep topical anesthesia with subconjunctival anesthesia.
