RESUMEN

BACKGROUND: Trachoma control programs use multiple approaches to identify individuals with trachomatous trichiasis (TT). Evidence is limited regarding which approaches are most effective and cost-efficient. METHODS: We evaluated the effectiveness of two TT case-identification approaches in Ethiopia: community mobilization to encourage self-referral for centralized screening and house-to-house screenings conducted by case finders. We compared the number of true cases found per 1000 population and costs associated with case identification under each approach, stratified by villages that received one or multiple screening visits. RESULTS: We conducted screenings in 396 villages. In villages receiving one house-to-house visit, case finders identified 14,229 suspected cases, of whom 10,513 (73.9%) presented for TT confirmation. A median of 17.2% (interquartile range [IQR]: 9.1%-27.8%) of those presenting truly had TT (positive predictive value). In single-visit villages, the community mobilization approach yielded higher rates of confirmed cases than the house-to-house approach (1.5 [IQR: 1.1, 2.6] vs. 1.1 [IQR: 0.5, 1.9] cases per 1000 population), and the median cost of identifying a TT case was less ($5.59 vs. $31.18) using community mobilization than house-to-house. In multiple-visit villages, additional screening visits increased the median rate of confirmed cases to 2.5 per 1000 population in community mobilization villages, but the rate remained unchanged in house-to-house villages. CONCLUSIONS: Community mobilization-based TT case finding had a higher yield than house-to-house, at a substantially lower cost. Future research should examine whether additional tools to aid case finders in their diagnosis increases case-finding efficiency and accuracy and whether TT prevalence and surgical program duration impact case-finding success.

RESUMEN

PURPOSE: Evaluation of the results of sutureless amniotic membrane transplantation (AMT) using a pediatric nasogastric tube (NGT) for patients with acute Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN) was aimed. METHODS: Twenty-six eyes of 13 patients with SJS/TEN with ocular involvement at a single tertiary care hospital between May 2020 and January 2022 were included in the study. An amniotic membrane was implanted to the ocular surface and conjunctival fornix using a modified symblepharon ring (MR) created by inserting NGT end-to-end. Patients were followed for at least 6 months. The mean duration of the surgery was recorded. The presence of corneal epithelial defect and vascularization, meibomian gland dysfunction (MGD) grade, conjunctival scarring, eyelid margin keratinization, symblepharon, and trichiasis were recorded. RESULTS: The mean age of the patients was 38.4±17.6 years. Amniotic membrane transplantation was performed only once for eight patients and twice for five patients. The mean duration of the surgery was 3.2±0.4 min. The modified symblepharon ring was removed 28 days after its application. At the first examination, 20 eyes (76.9%) had a corneal epithelial defect and 6 (23.1%) had early symblepharon. At the postoperative 6 months, although seven eyes (26.9%) had conjunctival scarring and 5 (19.2%) had eyelid margin keratinization, all patients were without any corneal defect, corneal vascularization, or symblepharon. Only 11 eyes (42.3%) showed MGD, and 1 eye (3.8%) showed trichiasis. CONCLUSIONS: This study showed that sutureless AMT using pediatric NGT could be a potentially fast and inexpensive treatment option for the treatment of SJS/TEN with ocular involvement at the bedside without the need for general anesthesia.

RESUMEN

PURPOSE: The purpose of this study was to assess the long-term outcomes of severe cicatricial entropion repair with mucous membrane grafting in patients with chronic cicatrizing conjunctivitis and report histopathological changes in the eyelid margin area. METHODS: Prospective interventional study included 19 patients with severe cicatricial entropion with trichiasis (N = 20 eyelids; 19 upper and 1 lower eyelid) who underwent anterior lamellar recession (with back cuts) and mucous membrane grafting cover for bare anterior tarsus, lid margin, and 2 mm of marginal tarsus, and had a minimum 6 months of follow-up. The anterior lamella and metaplastic eyelid margins were sent for routine Haematoxylin and Eosin and special staining with Masson trichrome stain. RESULTS: The etiologies were chronic Stevens-Johnson syndrome (N = 6), chemical injury (N = 11), and drug-induced pseudopemphigoid (N = 2). Five eyes had undergone entropion correction in the past, and 9 had electroepilation for trichiasis. Entropion was well corrected (without residual trichiasis) in 85% of eyelids with primary surgery. The etiology-wise success rates were 100% for Stevens-Johnson syndrome, 72.7% for chemical injury, and 100% for drug-induced pseudopemphigoid. Three eyelids with failure belonged to chemical injury, and trichiasis in these eyes could be managed with subsequent interventions except in 1 case. All eyelids had no entropion at a mean follow-up of 10.8 months (range, 6-18). Histopathological evaluation of anterior lamella (N = 10) and eyelid margins revealed significant fibrosis in subepithelial, perimysium (muscle of Riolan), and perifollicular areas. CONCLUSION: Anterior lamellar recession combined with mucous membrane grafting achieves good cicatricial entropion correction except in eyes with chemical injury. The eyelid margins in these eyes have persistent inflammation, and fibrosis involving lash follicles.

RESUMEN

PURPOSE: To describe the surgical technique and clinical outcomes of the glabellar flap and its modification for the reconstruction of the medial canthus following resection of tumors in three dogs and two cats. METHODS: Three dogs (7-, 7-, and 12.5-year-old mixed breeds) and two cats (10- and 14-year-old Domestic shorthair) presented with a 7-13 mm tumor affecting the eyelid and/or conjunctiva in the medial canthal region. Following en bloc mass excision, an inverted V-shaped skin incision was made in the glabellar region (i.e., the area between the eyebrows in humans). The apex of the inverted V-shaped flap was rotated in three cases, whereas a horizontal sliding movement was performed in the other two cases to better cover the surgical wound. The surgical flap was then trimmed to fit the surgical wound and sutured in place in two layers (subcutaneous and cutaneous). RESULTS: Tumors were diagnosed as mast cell tumors (n = 3), amelanotic conjunctival melanoma (n = 1), and apocrine ductal adenoma (n = 1). No recurrence was noted in a follow-up time of 146 ± 84 days. Satisfactory cosmetic outcome with normal eyelids closure was achieved in all cases. Mild trichiasis was present in all patients and mild epiphora was noted in 2/5 patients, but there were no associated clinical signs such as discomfort or keratitis. CONCLUSIONS: The glabellar flap was easy to perform and provided a good outcome in terms of cosmetic, eyelid function, and corneal health. Postoperative complications from trichiasis appear to be minimized by the presence of the third eyelid in this region.

RESUMEN

BACKGROUND: The management of cicatricial entropion and trichiasis represents a therapeutic challenge. The authors determined the long-term stability of combined surgical procedures in severe cases. METHODS: The authors retrospectively studied consecutive patients with severe upper eyelid cicatricial entropion and trichiasis treated between 2019 and 2021 at Beijing Tongren Eye Center. Combined surgical procedures adjusted to clinical evaluations were performed. Clinical characteristics, procedures, and surgical outcomes were retrieved. RESULTS: The authors included data on 58 eyelids (25 left and 33 right) from 39 patients (19 males and 20 females). The mean age was 54.81 years. Follow-up averaged 20.67 months. Common diagnoses were chemical injury, trachoma, and chronic conjunctivitis. Seven eyelids with eyelid margin entropion were successfully treated using anterior lamellar recession and gray line split. Seven eyelids with eyelid margin entropion and posterior lamellar deficits were effectively treated using anterior lamellar recession, gray line split, and posterior lamellar lengthening. Thirty-eight eyelids with recalcitrant eyelid margin entropion were treated using anterior lamellar recession and gray line split with graft, with a success rate of 94.74% and 89.47%, 3 and 6 months after the operation, respectively. Six eyelids with recalcitrant eyelid margin entropion and posterior lamellar deficits were effectively treated using anterior lamellar recession, gray line split with graft, and posterior lamellar lengthening. Among various grafts, pediculated orbicularis muscle was significantly different from banked sclera or resected tarsus ( P = 0.011, P < 0.001). CONCLUSIONS: In severe upper eyelid cicatricial entropion and trichiasis, combined surgical procedures showed good functional and cosmetic results with excellent long-term stability.

RESUMEN

OBJECTIVE: In the intermarginal split lamella with labial mucous membrane graft procedure to manage major trichiasis, the graft is usually sutured in the receptor bed using 6-0 polyglactin sutures. We aimed to compare the use of fibrin sealant to seal the graft to the receptor bed versus the conventional technique using sutures. METHODS: This is a retrospective comparative study of patients who underwent conventional intermarginal split lamella with labial mucous membrane graft or sutureless procedure using fibrin sealant (Tisseel, Baxter Healthcare Corp) between 2016 and 2021. Etiology of the trichiasis, procedure duration, postoperative discomfort and edema, complications, and follow-up period were extracted from these patients' charts. RESULTS: Twenty-seven eyelids from 19 patients underwent the procedure: twelve patients underwent the sutureless procedure, while seven underwent the conventional procedure. Mean follow-up was 8.4 ± 2.9 months and 13.7 ± 6.5 months for the sutureless and conventional groups, respectively. Patients who underwent the sutureless procedure reported no postoperative foreign body sensation, while 71.4% of patients who underwent the conventional procedure reported some degree of ocular discomfort. In the sutureless group, operating time and postoperative edema were significantly reduced. Labial mucous membrane graft dehiscence was observed in one eyelid (8.3%) on the first postoperative day in the sutureless group. No dehiscence was observed in the conventional technique group. CONCLUSION: The use of fibrin sealant showed to be a good alternative to conventional absorbable sutures. Advantages include expedited operating time, decreased postoperative discomfort, and expedite postoperative recovery.

RESUMEN

The great variety of orbital traumas can surprise and challenge specialists attempting to cure its consequences with the best possible outcome. This article presents a clinical case of a patient diagnosed with cicatricial deformity of the free edge and trichiasis of the upper eyelid in the lateral angle area, keratopathy, enophthalmos on the left side; posttraumatic defect of the inferior orbital wall; multiple foreign bodies in the orbit and maxillary sinus on the left side. Patient examination included conventional ophthalmological study methods, as well as multislice computed tomography with 3D-reconstruction. Surgical treatment required involvement of an ophthalmologist, an otorhinolaryngologist and a maxillofacial surgeon. The first stage of surgical treatment addressed the deformity of the lateral part of the upper eyelid margin including resection of its fragment, trichiasis surgery, and lateral canthoplasty. In the second stage, the multidisciplinary team of surgeons removed foreign bodies through combined subciliary and endonasal access with placement of a mandibular autograft onto the inferior orbital wall. Radiological examination should be done in all patients with trauma to the orbital area in order to detect latent injuries. When choosing a treatment strategy, specialists should be aware of trauma complicity and necessity to enlist a multidisciplinary medical team. Patients should be informed that sometimes the consequences of the trauma may not be treated completely.

RESUMEN

Leukotrichia is one of the difficulties of vitiligo treatment. Hair follicle transplantation is an efficient method to treat vitiligo-associated leukotrichia. A trichiasis electrolyzer, commonly used for treating trichiasis, can be used to damage and remove the depigmented hair follicles. To evaluate the efficacy of the electrolysis of depigmented hair using a trichiasis electrolyzer combined with single hair follicle transplantation for the treatment of vitiligo-associated leukotrichia. A total of 15 patients with stable vitiligo-associated eyebrow and eyelash leukotrichia were enrolled from Department of Dermatology, Hangzhou Third People's Hospital between January 2020 and January 2021. All patients were treated using a trichiasis electrolyzer combined with single hair follicle transplantation. The patients were followed up at the first week, the first month, the third month, and the sixth month after surgery. The texture and growth state of the transplanted hair were observed, and the number of surviving transplanted follicles and regenerating depigmented follicles were recorded. The transplanted hair grew as expected with natural shape. No local infection or obvious scar was observed. Most of the depigmented hair in the lesion area re-pigmented and only a few depigmented hairs regenerated. The average survival rate of the transplanted hair follicles was 71.6%, and the average regeneration rate of the depigmented hair was 11.6%. The electrolysis of depigmented hair using a trichiasis electrolyzer combined with single hair follicle transplantation was an effective and safe method to treat vitiligo-associated leukotrichia.

RESUMEN

BACKGROUND: Describing the pattern of pediatric eye diseases is necessary for appropriate eye care in children. This study explored the spectrum and characteristics of pediatric ophthalmic diseases in a typical tertiary ophthalmology hospital in China. METHODS: A retrospective study was conducted at a tertiary ophthalmology hospital between 2010 and 2019 in Guangzhou, China. This study included 44,552 inpatients who were younger than 18 years old. Demographic and diagnostic data were collected from the electronic medical record system. Multiphase regression analysis was used to estimate trends in the annual percentages of ten common ophthalmic diseases. RESULTS: From 2010 to 2019, 44,552 inpatients met the inclusion criteria. The majority were male (61.9%), aged 7 to 12 years (30.3%) and self-paying (56.6%). The top ten conditions were refractive error (41.2%), strabismus (36.1%), cataract (13.6%), trauma (11.8%), congenital ptosis (8.8%), tumor (8.1%), amblyopia (7.1%), glaucoma (7.0%), entropion and trichiasis of eyelid (7.0%), and retinal detachment (6.5%). The annual percentage changes (APCs) for refractive error, strabismus, and retinal detachment were 9.3% (95% CI, 8.1-10.5%), 4.7% (95% CI, 3.8-5.6%) and - 2.8% (95% CI, - 5.1% to - 0.4%) respectively. For trauma, the average APC (AAPC = -9.2%, (95% CI, - 12.1% to - 6.2%) decreased gradually from 2010 to 2015 (APC = -4.2% (95% CI, - 8.8-0.7%)) and decreased rapidly from 2015 to 2019 (APC = -15.1% (95% CI, - 21.0% to - 8.7%)). CONCLUSIONS: Pediatric ophthalmic diseases are common in China. Preventive strategies and health education aimed at the prevention of refractive error, strabismus, and entropion and trichiasis of eyelid will be crucial in reducing the burden of pediatric ophthalmic diseases on health care systems and human development.

RESUMEN

Amyloidosis is characterized by systemic or local deposition of amyloid fibrils outside organs and tissues. Amyloidosis is rarely seen on cornea. A 30-year-old woman patient had had trichiasis in both eyes for 8 years. Trichiasis was observed, which touched the cornea. Slit lamp microscopy showed white gelatinous droplet-like eminences and trichiasis in the lower cornea of the right eye. Optical coherence tomography showed that the lesion involved most of the cornea. Hematoxylin and eosin staining showed that most of the stroma stained red, with scattered inflammatory cells. High expression of lactoferrin was detected by mass spectrometry, and the case was diagnosed as secondary corneal lactoferrin amyloidosis in the right eye.

RESUMEN

OBJECTIVE: To describe a technique to repair feline eyelid agenesis using a hyaluronic acid (HA) subdermal filler injection to allow for acute soft tissue expansion, followed by a free labial mucocutaneous graft. MATERIALS AND METHODS: Thirty-nine colobomatous eyelids in 24 feline patients with secondary keratitis were recruited to the study group. RESULTS: Keratitis and trichiasis were markedly resolved in 27/39 (69.2%) eyelids after a single procedure. Post-operative HA subdermal filler injections were required to resolve 5/39 (12.8%) eyelids that had mild post-operative trichiasis, and 1/39 (2.5%) eyelids that had post-operative lateral canthal collapse. Complications occurred in 6/39 (15.4%) cases, consisting of distal graft necrosis (n = 2 eyes), suture rubbing the cornea (n = 2 eyes), moderate trichiasis (n = 1 eye) and graft adherence to the episclera (n = 1 eye). CONCLUSION: The technique was successful in enhancing corneal protection, cosmesis and eyelid function and should be considered as a surgical option for any degree of eyelid agenesis in feline patients.

RESUMEN

INTRODUCTION: The World Health Organization has identified management of postoperative trichiasis (PTT) as one of the key remaining areas of focus needed to eliminate blinding trachoma as a public health problem. We developed the Bevel-Rotation Advancement Procedure (B-RAP) to treat individuals who need repeat trichiasis surgery. METHODS: Scarring caused by trichiasis surgery can cause the eyelid to become thick and distorted, making repeat surgery more difficult. To minimize eyelid thickness following B-RAP, a beveled incision of the tarsus is made allowing a marginal rotation of the eyelash fragment. Dissection between the anterior and posterior lamellae above the beveled incision and removal of scar tissue allows the marginal rotation to be combined with a posterior lamellar advancement to treat severely scarred eyelids with PTT and eyelid contour abnormalities (ECAs). RESULTS: Two surgeons performed B-RAP on 44 eyelids of 30 patients with PTT. The number of prior trachomatous trichiasis (TT) surgeries ranged from 2 to more than 4. At the 3-6 months postoperative visit, 37 eyelids (84%) had no recurrence of PTT. Three eyelids had central lashes touching; the remaining eyelids with recurrent PTT had nasal and temporal lashes touching. Fifteen eyelids (34%) had ECAs, but only 1 was severe. CONCLUSIONS: B-RAP was developed considering the altered eyelid anatomy found in the postsurgical eyelid with TT. Thinning of the eyelash fragment and removal of postoperative scar tissue improves the ability to advance and stabilize the eyelash fragment after external rotation. B-RAP shows promise as a procedure for improving outcomes of repeat trichiasis surgery.

RESUMEN

A simplified grading system for trachoma was published by the World Health Organization (WHO) in 1987. Intended for use by non-specialist personnel working at community level, the system includes five signs, each of which can be present or absent in any eye: (i) trachomatous trichiasis; (ii) corneal opacity; (iii) trachomatous inflammation-follicular; (iv) trachomatous inflammation-intense; and (v) trachomatous scarring. Though neither perfectly sensitive nor perfectly specific for trachoma, these signs have been essential tools for identifying populations that need interventions to eliminate trachoma as a public health problem. In 2018, at WHO's 4th global scientific meeting on trachoma, the definition of one of the signs, trachomatous trichiasis, was amended to exclude trichiasis that affects only the lower eyelid. This paper presents the amended system, updates its presentation, offers notes on its use and identifies areas of ongoing debate.


En 1987, l'Organisation mondiale de la Santé a publié un système de codage simplifié du trachome. Destiné au personnel non qualifié travaillant au sein des communautés, il comporte cinq signes, chacun pouvant être présent ou absent dans l'un ou l'autre œil: (i) le trichiasis trachomateux; (ii) l'opacité cornéenne; (iii) l'inflammation trachomateuse ­ folliculaire; (iv) l'inflammation trachomateuse ­ intense; et enfin, (v) la cicatrice trachomateuse. Bien qu'ils ne soient ni parfaitement précis, ni totalement spécifiques au trachome, ces signes constituent des outils essentiels pour identifier les populations qui nécessitent une intervention afin d'éliminer le trachome en tant que problème de santé publique. En 2018, lors de la quatrième réunion scientifique mondiale sur le trachome, la définition de l'un des signes, le trichiasis trachomateux, a été modifiée pour exclure du système de codage le trichiasis qui n'affecte que la paupière inférieure. Ce document expose le nouveau système, actualise sa présentation, formule des remarques sur son utilisation et identifie les domaines qui font encore l'objet de débats.


En 1987, la Organización Mundial de la Salud (OMS) publicó un sistema de clasificación simplificado para el tracoma. Este sistema fue diseñado para que lo utilice el personal no especializado que trabaja a nivel comunitario e incluye cinco signos, cada uno de los cuales puede estar presente o ausente en los ojos: i) la triquiasis tracomatosa; ii) la opacidad corneal; iii) la inflamación tracomatosa-folicular; iv) la inflamación tracomatosa-intensa; y v) la cicatrización tracomatosa. Si bien no son perfectamente sensibles ni muy específicos del tracoma, estos signos han sido herramientas esenciales para identificar a las poblaciones que requieren intervenciones para eliminar el tracoma como problema de salud pública. En 2018, se modificó la definición de uno de los signos, la triquiasis tracomatosa, en la 4.ª Reunión Científica Mundial sobre el Tracoma de la OMS, para descartar la triquiasis que solo afecta al párpado inferior. En el presente documento se describe el sistema modificado, se actualiza su presentación, se ofrecen observaciones sobre su aplicación y se identifican los ámbitos de debate en curso.

RESUMEN

BACKGROUND: Surgery for trichiasis is one of the pillars of the World Health Organization's strategy for global elimination of trachoma as a public health problem. A high incidence of post-operative trichiasis or other poor surgical outcomes could jeopardize these efforts. In this review, we aimed to summarize the reported incidence of post-operative trichiasis and other poor outcomes of trichiasis surgery in Africa. METHODS: We conducted a systematic literature search using PubMed, Academic Search Premier, Africa-Wide Information, CINAHL and Health Source Nursing through EBSCOhost, Web of Science, and the Cochrane Central Register of Controlled Trials. Reference lists of included studies were also reviewed to identify further potentially relevant publications. All observational and interventional studies that measured post-operative trichiasis in Africa as an outcome of trichiasis surgery were included. RESULTS: Thirty-five papers reporting on 22 studies (9 interventional,13 observational; total 13,737 participants) met the inclusion criteria. The reported incidence of post-operative trichiasis in the included studies ranged from 2% (at 6 weeks after bilamellar tarsal rotation) to 69% (at 3 weeks after anterior lamellar repositioning). The incidence varied by surgical procedure, study design, and length of follow-up. CONCLUSION: Trichiasis surgical outcomes should be improved. National trachoma programmes could benefit from identifying and adopting strategies to improve the performance and quality of their surgical service.

RESUMEN

BACKGROUND: Whilst previous work has identified clustering of the active trachoma sign "trachomatous inflammation-follicular" (TF), there is limited understanding of the spatial structure of trachomatous trichiasis (TT), the rarer, end-stage, blinding form of disease. Here we use community-level TF prevalence, information on access to water and sanitation, and large-scale environmental and socio-economic indicators to model the spatial variation in community-level TT prevalence in Benin, Cote d'Ivoire, DRC, Guinea, Ethiopia, Malawi, Mozambique, Nigeria, Sudan and Uganda. METHODS: We fit binomial mixed models, with community-level random effects, separately for each country. In countries where spatial correlation was detected through a semi-variogram diagnostic check we then fitted a geostatistical model to the TT prevalence data including TF prevalence as an explanatory variable. RESULTS: The estimated regression relationship between community-level TF and TT was significant in eight countries. We estimate that a 10% increase in community-level TF prevalence leads to an increase in the odds for TT ranging from 20 to 86% when accounting for additional covariates. CONCLUSION: We find evidence of an association between TF and TT in some parts of Africa. However, our results also suggest the presence of additional, country-specific, spatial risk factors which modulate the variation in TT risk.

RESUMEN

Epidermal growth factor receptor tyrosine kinase inhibitor therapy has been increasingly employed in the treatment of a variety of tumors. The authors report the rarely documented side effect of trichiasis with the use of Afatinib in a patient with spinal chordoma and review-related literature. A 67-year-old lady was referred to the oculoplastic service with a 3-month history of ocular irritation and pain associated with blurred vision. She has a 4-year history of spinal chordoma treated with daily Afatinib 50 mg over the past 6 months. Clinical examination revealed trichomegaly and trichiasis affecting all 4 eyelids associated with blepharitis, conjunctival, and corneal abrasion on fluorescein staining. Hypertrichosis of the eyebrow bilaterally was also present. Afatinib and other epidermal growth factor receptor tyrosine kinase inhibitor-associated changes to eyelash and eyebrow hair is a result of epidermal growth factor receptor pathway activation in keratinocytes results in remodeling of the hair follicle. This results in the variation in the severity of clinical presentation of trichiasis.

RESUMEN

IMPORTANCE: Australia is the only developed country to still have pockets of endemic trachoma. The research provides up-to-date, population-based prevalence data of later complications of trachoma amongst a national sample of Indigenous adults. BACKGROUND: To report the prevalence of trachomatous trichiasis (TT) in Indigenous Australians aged 40 years and older. DESIGN: Population-based cross-sectional study. PARTICIPANTS: A total of 1738 (41% male) Indigenous Australians aged 40 years or older, living amongst 30 randomly selected Australian sites, stratified by remoteness. METHODS: Anterior segment examination was performed and trachoma grading for the presence of TT and corneal opacification (CO) was conducted using the WHO (WHO) simplified grading system. MAIN OUTCOME MEASURES: Prevalence of TT. RESULTS: A total of three (0.17%) participants had TT, and there were no confirmed cases of trachomatous CO in the NEHS. All three participants with TT were female and aged 40 years or older. Although they had likely spent their childhoods in more remote areas, two of the three confirmed cases resided in an urban and outer regional area at the time of their examinations. CONCLUSIONS AND RELEVANCE: Our data are in line with ongoing national trachoma surveillance reports that suggest the prevalence of late sequences of trachoma appear to be decreasing in Australia.

RESUMEN

PURPOSE: To evaluate the use of autogenous tarsal graft for surgical correction of lower eyelid trichiasis associated with eyelid thinning. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

RESUMEN

Linear scleroderma en coup de sabre with ophthalmic findings has been previously described in the literature on numerous occasions. A 57-year-old woman presented with focal trichiasis secondary to tarsal thinning, adjacent to a linear brow and forehead deformity consistent with linear scleroderma en coup de sabre. Cases of linear scleroderma en coup de sabre involving the eyelids have been reported, most often with madarosis, ptosis, or skin atrophy; however, to the authors' knowledge, this is the first reported case of linear scleroderma associated with trichiasis and involvement of the deeper eyelid tissues, particularly the tarsus.

RESUMEN

The purpose of this article is to analyze the outcomes of two surgical techniques to treat major trichiasis. A retrospective chart review of 67 patients (89 eyelids) with major trichiasis was performed who underwent surgical treatment using one of two techniques: intermarginal split lamella with graft (ISLG group) or lid lamella resection (LLR group). There were 30 lids in the ISLG group with mean patient age of 71.8 years and 63.3% were females. There were 59 lids in the LLR group with mean patient age of 72.5 years and 52.5% were female. The minimum postoperative follow up was six months. Statistical analysis included descriptive measures, Goodman association test for contrasts between and within multinomial populations and nonparametric Mann-Whitney test for comparison between groups. P < 0.05 was considered statistically significant. The underlying causes of trichiasis were blepharitis (37.07%), chronic meibomitis (21.3%), multiple causes (20.2%), ectropion (11.2%), actinic keratosis (6.7%), or prior ocular surgery (3.3%). Postoperatively, in the ISLG group, there were 20% lids with complete success, 50% underwent laser or electrolysis, 16.7% required further surgery, and 13.3% were unsuccessful. Postoperatively, in the LLR group, there were 47.5% eyelids with complete success, 46.7% underwent laser or electrolysis, 6.8% required further surgery, and 5.1% were unsuccessful. There was a higher statistical chance of complete success with LLR (P < 0.05). LLR is superior to ISLG surgery for the treatment of major trichiasis. There is a greater chance of success with LLR and it is technically simpler.
