Prevalence of Post-Operative Trichiasis in Southern Ethiopia, 2021: A Community Based Cross Sectional Study.

Post-operative trichiasis (PTT) is a major challenge following corrective eyelid surgery for trachomatous trichiasis. There is a scarcity of research on post-operative trichiasis in Southern Ethiopia, particularly in the study area. This study aimed to assess the prevalence of post-operative trichiasis in patients who underwent corrective surgery. To assess the prevalence of post-operative trichiasis in the Gamo Zone in Southern Ethiopia in 2021. A descriptive community-based cross-sectional study was conducted in the Dita district, Southern Ethiopia. The data were collected between 2014 and 2020. Three Qualified trachoma trichiasis (TT) graders working on a trachoma impact survey were recruited for this study. Eye examinations were performed by graders on all study subjects using a loupe to identify post-operative trichiasis. All patients underwent upper eyelid surgery only. A systematic sampling technique was used to select 459 participants from the TT Surgery Logbook. Of the 459 study participants, more than three quarter 353 (76.9%) were female. The mean age of the study subjects was 48.38 years with a standard deviation of +-10.4. A total of 10 upper eyelids (7 bilateral and 3 left upper eyelids) underwent PTT. The prevalence of post-operative trichiasis in the study area was 2.2% (95% CI: 0.9-3.5%. Fourteen (4.7%) unoperated upper eyelids developed trichiasis infection. A few patients had left and right lower eyelid trichiasis (6/459 [1.3%] and 3/459 [0.7%], respectively). The prevalence of post-operative trichiasis in the study area was similar to that recommended by the World Health Organization (WHO) recommendation range. Trachoma trichiasis was observed on the lower and upper unoperated eyelids of the study participants. Therefore, sustainable interventions should be considered in the study area for all the components of the SAFE strategy, particularly on S component.

Prospective audit of the phenotype, causes and correlates of trachomatous and non- trachomatous trichiasis in a peri-elimination setting.

To explore the burden, clinical features and associations of trichiasis due to trachomatous and non-trachomatous aetiologies. Consenting patients presenting with trichiasis of either eyelid (of one or both eyes) attending the outpatient department, cornea and oculoplasty clinics of a tertiary eye care hospital in New Delhi between August 2018 to March 2020 were included. A comprehensive examination including visual acuity and anterior segment evaluation and photography was performed. Grade of trichiasis, laterality, presence and grade of entropion, and information on corneal opacity, conjunctival scarring, Herbert's pits, and pannus, if present, were recorded in the case record form. Overall, 302 patients (454 eyes) with trichiasis were recruited. The most common attributed cause of upper eyelid trichiasis (276 patients, 405 eyes) was trachoma (26% of patients), followed by Stevens-Johnson syndrome (23%), blepharokeratoconjunctivitis (17%) and old age (10%). A total of 296/405 eyes (73%) had some form of corneal involvement. Trachoma was not identified as the cause of trichiasis in any eye with lower eyelid-only disease. Only about a quarter of upper eyelid trichiasis in this peri-elimination setting was attributed to trachoma. A distinction between trachomatous and non-trachomatous trichiasis is imperative to meaningfully determine whether elimination of trachoma as a public health problem has occurred. These data may have implications for population-based estimates of TT prevalence in India and other peri-elimination settings.

Interlamellar Autogenous Tarsal Graft for the Correction of Lower Eyelid Trichiasis Associated With Eyelid Margin Thinning.

To evaluate the use of autogenous tarsal graft for surgical correction of lower eyelid trichiasis associated with eyelid thinning. A total of 23 eyelids of 19 consecutive patients with trichiasis were operated with a variant of the Van Millingen procedure. The surgery consisted of interposing a 3-mm high fragment of autogenous ipsilateral upper eyelid tarsus corresponding to the trichiasis segment between the pretarsal anterior lamella and the lower tarsal plate. Preoperative assessment included quantification of eyelid thickness on the midpoint of the segment with trichiasis, biomicroscopy of the eyelid margin and location of the trichiasis. All patients were examined at 1, 3, 6, and 12 months after surgery. Eyelid thickness was measured at 1 month and 12 months of follow up. Preoperatively the mean thickness of the eyelid margin was 0.99 mm ± 0.06 standard error. One month postoperatively eyelid thickness increased to 2.08 ± 0.28 standard error, decreasing over time to reach 1. 48 mm ± 0.18 standard error 1 year after surgery, a value that did not differ from that of the control group. Small granulomas were diagnosed only in the early phases of the postoperative period. Trichiasis recurrence was seen in just 1 eyelid. Isolated abnormal lashes lateral or medial to the graft were present in 5 eyelids at the end of the study. Autogenous tarsal grafts placed parallel to the lower tarsus are a good option both to correct misdirected eyelashes and to restore normal lower eyelid thickness.

Het gelijktijdig voorkomen van een plaveiselcelcarcinoom en hemangiosarcoom in de cornea bij een kat

Een veertien jaar oude, vrouwelijke, gesteriliseerde huiskat werd aangeboden omwille van een uitgesproken donker roodverkleuring van de cornea van het linkeroog. Het oog vertoonde eveneens trichiasis van het bovenooglid, entropion van het onderooglid en een uitgesproken symblefaron. Het rechteroog vertoonde trichiasis van het bovenooglid, entropion van het onderooglid, een uitgesproken symblefaron en chronische stromale en ulceratieve keratitis. Aan de hand van een biopsie van de cornea van het linkeroog werd een plaveiselcelcarcinoom gediagnosticeerd en het linkeroog werd vervolgens weggenomen. Histologisch onderzoek van de cornea toonde met bloed gevulde kanaalvormige structuren van verschillende grootte, die op bloedvaten geleken en afgelijnd waren door spindelvormige cellen. In het centrale deel van de cornea was een uitgesproken hyperplastisch epitheel aanwezig met infiltratie van atypische cornea-epitheelcellen in het oppervlakkige stroma. Zowel een primair hemangiosarcoom als een primair plaveiselcelcarcinoom in de cornea werd gediagnosticeerd. In deze casuïstiek wordt het zeldzame voorkomen van meerdere primaire tumoren in dezelfde anatomische structuur beschreven.

Clinical effects of intra-lamellar orbicularis dissecting micro-traumatic double eyelid surgery for the treatment of adolescent upper eyelid trichiasis

Objective To evaluate the clinical effects of intra-lamellar orbicularis dissecting micro-traumatic double eyelid surgery for the treatment of adolescent upper eyelid trichiasis. Methods Three cutaneous micro-incisions following intra- and sub-lamellar orbicularis dissections were performed and the deep orbieularis and suborbicularis fat pad between the intended eyelid crease and 1 mm above the eyelid margin were resected. The subcutaneous orbicularis was fixed to the exposed levator aponeurosis at the medial, center and lateral regions. For the quantitative analysis, the entire eyelid margins' eyelashes were equally divided into three sections and the eyelashes lift-up angle (LA), the body curl-up angle (BC) and the end curl-up angle (EC) were compared before and after surgery in each section, respectively. Results One hundred and fourteen eyes of 57 cases were followed up during 24-30 months. Compared to the LA before surgery and 2 years after surgery, it was changed from (26.37±9.67)° to (55.42± 10.03)° in section Ⅰ , and from (22.03±11.64)° to (50.03±10.02)° in section Ⅱ , and from (25.31±8.01)° to (64.05±8.33)° in section Ⅲ. There were no significant changes of BC and EC during following-up. Con-clusions For the adolescent upper eyelid trichiasis, the intra-lamellar orbicularis dissecting micro-trau-matic double eyelid surgery could acquire satisfactory aesthetic appearance and stable eyelashes'position at the same time.
