Résumé :
Trichiasis surgery is a pillar of the World Health Organization (WHO) strategy for trachoma control. Visual acuity improvement and symptomatic relief follow surgery for trichiasis, and non-ophthalmologists have been trained to carry out the surgery in trachoma-endemic communities. However, recurrence of trichiasis following surgery is unfortunately common, which can undermine public confidence in national trachoma programs. Recurrence of trichiasis following surgery is more likely in high-risk patients (those with previous surgery or who have severe entropion). The most common cause appears to be surgeon skill, with large variations in recurrence reported by surgeon. Proper training, standardization, certification, and supervision would reduce adverse outcomes after surgery. Ideally, recurrence should be 10% at one year, or less with post-operative use of a single dose of azithromycin. The post-operative environment, and acquisition of bacterial infection, may also play a role in recurrence of trichiasis, but it is not clear thatChlamydia trachomatisis important. Efforts to ensure good outcomes of trichiasis surgery for trachoma-endemic, and formerly endemic, countries are imperative. Even with control of active trachoma, trichiasis cases will continue to emerge for years. Detection of these cases, proper surgery, and case management are critical to achieving all the goals of the elimination of blinding trachoma.

Résumé :
Background: Trachomatous trichiasis (TT) may lead to disability, impeding productive activities, resulting in loss of income. This study was conducted to determine if trichiasis surgery improves participation in productive and leisure activities, and ability to perform activities without difficulty or assistance. Methods: We recruited 1000 adults with trichiasis (cases) and 200 comparison participants, matched to every fifth trichiasis case on age (+/- two years), sex and location. The ‘Stylised Activity List’ tool, developed for the World Bank Living Standard Measurement Survey, was adapted to collect data on activity in the last week (participation in activity, difficulty with activity, requirement of assistance for activity), at baseline and 12 months later. All trichiasis cases received trichiasis surgery at baseline. Random effect logistic regression was used to compare cases and comparison participants. Results: There was strong evidence that trichiasis surgery substantially improves the ability of trichiasis cases to perform all the productive and leisure activities investigated without difficulty, with large increases in processing agricultural products, 21.1% to 87.0% (p<0.0001), farming, 19.1% to 82.4% (p<0.0001), and fetching wood, 25.3% to 86.0% (p<0.0001). Similarly, there was a significant increase in the proportion of cases who could perform activities without assistance, with the largest increases in animal rearing 54.2% to 92.0% (p<0.0001) and farming 73.2% to 96.4% (p<0.0001). There was no change in the proportion of comparison participants performing activities without difficulty or assistance. The change in most of the activities in cases was independent of visual acuity improvement and recurrent TT at 12 months. One year after trichiasis surgery, the proportion of cases reporting ocular pain reduced from 98.9% to 33.7% (p<0.0001). Conclusions: Eyelid surgery for TT improves functional capabilities regardless of vision gains. These data lend strong support to the view that TT surgery improves function and contributes to improved household income and wealth.

Résumé :
Background Trachomatous trichiasis is the leading infectious cause of blindness worldwide. The World Health Organization recommends eyelid surgery to reduce the risk of visual impairment from trichiasis. Unfortunately, the number of cases operated has grown less than expected. An understanding of barriers is fundamental for instituting measures to increase surgical uptake. Therefore, the aim of this study was to explore barriers of TT surgery implementation. Methods A qualitative study design was employed in December 2019. Purposive sampling technique was used to select three districts from Gamo zone, Southern Ethiopia. We conducted 9 FGDs and 12 in-depth interviews. Data was collected by audio tape recorder in Amharic and Gamogna languages and then transcribed to English language. The recorded interviews and focus group discussions were transcribed to verbatim (written text) and thematic analysis was done manually and reported accordingly. Findings we explored a number of barriers that hindered implementation of trichiasis surgery. The recurrence of trichiasis after surgery was the main challenges faced by operated individuals. The other barriers reported are negative perception towards trichiasis surgery, lack of logistic and supplies, transportation access problem for remote communities, inadequate trained health professional, less commitment from higher officials, lack of interest of integrated eye care workers due to incentive issues, believes of patients waiting supernatural power for healing service and carelessness of patients to undertake operation. Conclusion and recommendation Post-surgical trichiasis, lack of commitment from government officials and negative perception of patients towards the disease were considered as the reported barriers for implementation of trachomatous trichiasis. Closely supervising the integrated eye care workers would be the first task for district health offices to increase the uptake and improve the quality of service. Logistics and supplies should be made available and adequate to address all affected people in the community.

Résumé :
Background High incidence of post-operative trichiasis and other poor outcomes after surgery in most trachoma-endemic settings poses a major challenge to global elimination of trachoma. This systematic review aimed to assess the incidence of post-operative trichiasis and other poor outcomes of trichiasis surgery in Africa, based on findings of observational and interventional studies. Search methods We searched PubMed, Academic Search Premier, Africa-Wide Information, CINAHL and Health Source Nursing through EBSCOhost, Web of Science [all databases], and Cochrane Central Register of Controlled Trials for relevant studies on the subject. We also searched the reference lists of included studies to identify further potentially relevant studies. We included all observational and interventional studies that measured post-operative trichiasis as one of the primary outcomes. Only studies conducted in Africa were included in this review. Data collection and analysis Two reviewers independently screened the titles and abstracts, selected and assessed the articles for inclusion in this review. Any disagreements were resolved through discussion or by consulting a third reviewer. Where necessary, the corresponding authors of included studies were contacted to provide any missing data. Our primary outcome was post-operative trichiasis, which was defined as any eyelash touching the globe at different time points after surgery. Main results Thirty-five studies, including 12,943 participants, met the inclusion criteria. A number of the studies included in this review utilized the same data to measure the incidence of post-operative trichiasis and other poor outcomes over different follow-up periods. Overall, a review of the included studies revealed a pattern of high incidence of post-operative trichiasis and other poor outcomes ranging from 2.3 at 6 weeks to 65% at 7 years. This incidence varied by type of study design, surgical procedure and technique used as well as the follow up period among other factors.

Résumé :
Entropion is a posterior rotation of the upper or lower lid margin against the globe; the causes include involutional changes within the eyelid tissues or cicatricial shortening of the posterior lamella of the eyelid. Congenital lower lid entropion is rare and results from an excess of skin and orbicularis oculi muscle being only loosely attached to the eyelid retractors. The symptoms of entropion—which include ocular irritation, lid spasm, pain, redness, and watering—are worse in the presence of a keratinized lid margin (occurring in cicatricial disease) and where the ocular surface is compromised. Discomfort may lead to secondary blepharospasm, which exacerbates the entropion by causing the preseptal part of the orbicularis muscle to override the pretarsal component. The eyelids and globe should be examined to identify underlying causative factors—in particular the degree and position of tissue laxity, the position of the eyelid margin and lashes, and the thickness of the tarsus. Any secondary effects of entropion, both within the lid and on the ocular surface, should also be noted. 7-1-1 Tissue Laxity. Aging of collagen and the force of gravity leads to eyelid laxity and an excess of tissues, particularly the anterior lamella of the lid. Stretching of the orbicularis muscle and canthal tendons results in horizontal laxity, and eyelid stability is further compromised by enophthalmos due to age-related fat atrophy. Where there is a relative dissociation between the anterior and posterior lamellae, the preseptal orbicularis muscle overrides the pretarsal muscle, leading to eyelid inversion, and this effect is exacerbated both by laxity of the lower lid retractors and age-related tarsal atrophy. Tissue laxity in the absence of orbicularis overriding tends to cause ectropion; with complete loss of retractor action, this can result in complete eversion of the tarsus (“shelf ectropion”). Horizontal laxity of the eyelid tissues is assessed by grasping the lid skin and applying gentle traction in the appropriate direction. The overall horizontal laxity is judged by the extent to which the eyelid can be parted from the globe—greater than about 6 mm is abnormal for a lower eyelid—and by the speed with which the retracted lid returns to the surface of the globe (the “spring-back” test).
