MATERIAL AND METHOD An interventional case series reviewed the segmental trichiasis and distichiasis patients who were treated with folliculectomy in the Ophthalmology Department, King Chulalongkorn Memorial Hospital. The data was collected from January 1997 to D...
Some time ago in another paper there was a symposium on the subject of which was the best operation for trichiasis. The contributors described many methods, but here in India where trichiasis is so common the operation performed by Anagnostakis has not received the attention which it deserves, so I wish to bring it before the attention of your readers. During the past three months I have perfor...
Trachoma is the leading infectious cause of blindness worldwide. Corneal scarring, which causes trachomarelated blindness, occurs when the upper eyelashes are turned inward and rub on the eye (cornea). This is called trichiasis, and if the lid margin turns inward, the term entropion is used. Currently, there are an estimated 8.2 million people with trichiasis and 3.1 million people are blind fr...
BACKGROUND We investigated vision status associated with trachomatous trichiasis (TT) and explored age-sex patterns of low vision and blindness associated with trichiasis in Mankien district of southern Sudan where trachoma prevention and trichiasis surgery were absent. METHODS A population based survey was undertaken and eligible persons underwent eye examination. Visual acuity (VA) was test...
Trichiasis is the sight-threatening consequence of conjunctival scarring in trachoma, the most common infectious cause of blindness worldwide. Trachomatous trichiasis is the result of multiple infections from childhood with Chlamydia trachomatis, which causes recurrent chronic inflammation in the tarsal conjunctiva. This produces conjunctival scarring, entropion, trichiasis, and ultimately blin...
BACKGROUND Uncontrolled trachoma is a leading cause of blindness. Current global trachoma burden summary measures are presented as disability adjusted life years but have limitations due to inconsistent methods and inadequate population-based data on trachomatous low vision and blindness. We aimed to describe more completely the burden of blinding trachoma in Southern Sudan using health expecta...
BACKGROUND Evidence of widespread distribution of trachoma in Egypt had not been clarified as previous surveys were limited to individual communities which may not have been representative of the general population. The Nile Delta of Egypt presents a unique environment for trachoma to persist. Economic improvements in the past decade have affected even the poorest rural environments; availabili...
The objective of the present study was to describe, for the first time in Brazil, the use by a non-ophthalmologist of a community-based marginal rotation procedure by a posterior approach in the indigenous population from the Upper Rio Negro basin. Seventy-three upper eyelids of 46 Indians (11 males and 35 females) with cicatricial upper eyelid entropion and trichiasis were operated in the Indi...
PURPOSE To determine the prevalence of trachomatous inflammation - follicular (TF) and trichiasis in each of the 20 local government areas (LGAs) of Bauchi State, Nigeria. METHODS We undertook a population-based prevalence survey in each LGA in Bauchi State, employing the Global Trachoma Mapping Project methodology. We used a 2-stage, systematic and quasi-random sampling strategy. Using proba...
PURPOSE To determine the local government area (LGA)-level prevalence of trachoma in all 34 LGAs of Katsina State. METHODS A population-based prevalence survey was conducted in each LGA of Katsina State, using the Global Trachoma Mapping Project methodology. We used a 3-stage cluster random sampling strategy to select 25 households from each of 25 clusters. We examined all residents of select...
