Evaluating the Effectiveness of Lacrimal Gland Botulinum Toxin Using the TEARS Score.

PURPOSE: Botulinum toxin (BoNTA) lacrimal gland injections are one treatment option for managing epiphora. Outcomes for epiphora in existing studies are subjective and lack grading. This study utilized validated grading instruments to evaluate the efficacy of BoNTA lacrimal gland injections. METHODS: Prospective study evaluating the TEARS score and quality of life in patients receiving incobotulinum toxin (Xeomin) lacrimal gland injections for epiphora. Epiphora was graded using the TEARS score. Quality of life was evaluated using the watery eye quality of life score. Etiology, benefit duration, complications and additional injections were recorded. RESULTS: Of the 28 patients, (median age 67.5 years), 19 (68%) had facial palsy gustatory epiphora (GE). Median effect duration was 13 weeks. Improvements in tearing frequency (T), clinical effects (E), and activity limitation (A) were seen in 57%, 57%, and 71% of patients, respectively. Median watery eye quality of life score improved from 42.4/100 ± 10.1 to 10.6 ± 15.5 (p < 0.001). Alongside crocodile tears, reflex tearing R-scores improved in 68% of patients with GE vs. 11% with non-GE causes (p = 0.004618). In total 89% of patients with GE and 56% with non-GE requested repeat injections. Self-reported percentage improvement ranged from 0% to 100% (median 60%, interquartile range 10%-76.25%). CONCLUSIONS: This is the first study reporting the outcomes of BoNTA lacrimal gland injections using validated TEARS and watery eye quality of life scores. Clinical and quality of life improvements are seen in most patients. Patients with GE achieve an additional improvement in dry eye-related reflex tearing alongside crocodile tears which both improve with BoNTA. TEARS data supports using BoNTA in these patients and is a useful validated grading instrument for epiphora.

Post-traumatic canalicular fistula: description and review of literature - SALDO update study (SUP) - paper II.

PURPOSE: To discuss the clinical spectrum and management strategies in patients with post-traumatic canalicular fistula (PTCF). METHODS: Retrospective, interventional case series of consecutive patients diagnosed with PTCF over a 6-year study period between June 2016 and June 2022. The demographics, mode of injury, location, and communication of the canalicular fistula were noted. The outcomes of several management modalities including dacryocystorhinostomy, lacrimal gland therapies, and conservative approaches were assessed. RESULTS: Eleven cases with PTCF over the study period were included. The mean age at presentation was 23.5 years (range: 6-71 years), with male: female ratio of 8:3. The median time interval between trauma to presentation at the Dacryology clinic was 3 years (range: 1 week to 12 years). Seven had iatrogenic trauma and four had the canalicular fistula following primary trauma. Management modalities pursued include conservative approach for minimal symptoms, and dacryocystorhinostomy, dacryocystectomy, and lacrimal gland botulinum toxin injection. The mean follow-up period was 30 months (range: 3-months-6 years). CONCLUSION: PTCF is a complex lacrimal condition and the management of the PTCF needs a tailored approach guided by its nature and location and patient symptomatology.

Hemolacria or bloody tears in presumed lacrimal endometriosis: a case report / Hemolacria o lágrimas hemáticas en sospecha de endometriosis lacrimal: reporte de un caso

Background: Hemolacria or the presence of blood in tears is a rare condition, and there are only a few cases reported in the literature. Hemolacria is associated with multiple underlying diseases, including vicarious menstruation due to extragenital endometriosis. Case report: We present a 26-year-old woman with hemolacria and abdominal pain related to her menstrual cycle. The patient was diagnosed with bilateral ovarian endometriomas. After ruling out other possible causes of hemolacria, a progestin-only treatment was applied, with improvement of the abdominal pain and complete remission of hemolacria. Conclusions: When faced with hemolacria, a thorough anamnesis and physical examination must be performed, sometimes involving more than one specialist to reach a diagnosis. Considering hemolacria is a sign of a subjacent pathology, its treatment should be specific one for the disease in each case.

Antecedentes: La hemolacria o presencia de sangre en las lágrimas es una afección poco frecuente y sólo hay unos pocos casos descritos en la literatura. La hemolacria se asocia a múltiples enfermedades subyacentes, incluida la menstruación vicaria debida a endometriosis extragenital. Caso clínico: Presentamos a una mujer de 26 años con hemolacria y dolor abdominal relacionado con su ciclo menstrual. La paciente fue diagnosticada de endometriomas ováricos bilaterales. Tras descartar otras posibles causas de hemolacria, se aplicó un tratamiento sólo con progestágenos, con mejoría del dolor abdominal y remisión completa de la hemolacria. Conclusiones: Ante una hemolacria se debe realizar una anamnesis y exploración física minuciosa, en la que a veces interviene más de un especialista para llegar al diagnóstico. Teniendo en cuenta que la hemolacria es signo de una patología subyacente, su tratamiento debe ser el específico para la enfermedad en cada caso.

Improvement in Epiphora Using TEARS Grading Following Surgical Treatment of Meibomian Gland Inversion in Patients With Facial Nerve Palsy.

PURPOSE: To assess epiphora outcomes using the TEARS grading score in patients with concomitant meibomian gland inversion (MGI) and facial nerve palsy (FNP) undergoing correction of MGI. METHODS: Retrospective, 5-year, noncomparative, single-center study of patients with MGI and FNP, treated with MGI correction, under the supervision of a single surgeon. A validated "TEAR" score was used to assess changes in epiphora. RESULTS: Ten patients with FNP, MGI, and epiphora were analyzed from a group of 160 patients with FNP who underwent MGI surgery between 2017 and 2022. The mean age at surgery was 50 years (range, 13-76 years). T, E, and A scores significantly improved (p < 0.05). Eighty percent of patients saw a reduction in tearing frequency (T), with 60% gaining ≥ 2-grade improvement. Improvements in clinical effects (E) and activity limitation (A) were seen in 80% of patients, with 40% and 50% gaining ≥ 2-grade improvement, respectively. R scores (related to reflex tearing) improved by 60%, with 40% seeing ≥ 2-grade improvement. Nine patients (90%) improved symptomatically with an average improvement "S" score of 65% over a mean follow-up period of 30 months. All patients demonstrated restoration of the normal anatomical position of the meibomian glands. CONCLUSIONS: MGI can cause epiphora in patients with FNP and may explain cases where symptoms persist despite standard surgical intervention. This study provides proof of concept that MGI correction can improve epiphora and that identifying MGI may be considered a critical step in the treatment algorithm for epiphora in patients with FNP.

[The role of miRNA in the pathogenesis of diseases associated with functional dysregulation of the lacrimal gland]. / Rol' mikroRNK v patogeneze zabolevanii, svyazannykh s narusheniem funktsii sleznoi zhelezy.

At this time, the mechanism causing lacrimal gland dysfunction is not understood completely. In diseases associated with lacrimal gland involvement (Sjogren's syndrome, sarcoidosis, IgG4-associated disease, etc.) patients have been observed to experience elevated cellular apoptosis, active production of autoantibodies to glandular tissue, increased level of pro-inflammatory cytokines, functional disruption of signaling molecules leading to changes in tear production. Difficulties in differential diagnosis of lacrimal gland dysfunction in above-listed diseases are associated, on the one hand, with similarity of the clinical picture of ophthalmological manifestations, and on the other hand - with complicated morphological interpretation of changes in the glandular tissues. In this view, miRNA is a promising diagnostic and prognostic marker that would help with differential diagnosis as well as with choosing the treatment tactics. Methods of molecular profiling and identification of "molecular phenotypes" of lacrimal gland and ocular surface damage will allow the use of miRNA as biomarkers and prognostic factors for personalized treatment.

[Lacrimal canalicular transposition for lower canaliculus repair: About four cases]. / Reconstruction du canalicule inférieur par transposition canaliculaire : à propos de quatre cas.

The main function of the eyelids is to support and protect the globe. The lower eyelid and medial canthus are often the location of malignant tumors that can be locally aggressive and require disfiguring surgeries. Chronic epiphora often appears in cases of inadequate reconstruction in this location and can require secondary procedures. We report four cases of medial canthus repair after tumor removal with loss of the inferior canaliculus. The ipsilateral superior canaliculus was removed before being transposed into the lower eyelid. This simple method allows for complete canalicular reconstruction. It obviates the need for artificial material and its potential associated complications. It has the advantage of a one-step eyelid and canalicular reconstruction and prevents epiphora after tumor resection.

Functional epiphora: an under-reported entity.

PURPOSE: To determine the etiology of epiphora in a tertiary Australian lacrimal clinic and highlight the high proportion of 'functional' cases. METHODS: Single-center retrospective review: Records of adult patients presenting to a tertiary lacrimal clinic from January 2011 to February 2021 with epiphora were reviewed. Patients underwent testing with syringing/probing and lacrimal imaging to reach a diagnosis of functional epiphora. Functional epiphora was diagnosed based on the exclusion of alternate causes of epiphora on clinical examination, patent lacrimal syringing, normal dacryocystography, and delay on dacryoscintigraphy. RESULTS: Five hundred and seventy-six symptomatic eyes of 372 adult patients (mean 66.2 ± 15.5 years, 63.4% females) with epiphora were evaluated for causes. Post-sac obstruction (stenosis/complete obstruction) and functional epiphora (non-anatomical delay) were the most common causes of presentations to the lacrimal clinic (26% each). Functional epiphora with post-sac delay was substantially more common than functional epiphora with pre-sac delay (89% vs. 11% of functional epiphora cases). In 16% of the cases, no cause for the epiphora was found while more than one cause (multifactorial) was present 11% of the time. CONCLUSION: Functional epiphora was found to be as common as a nasolacrimal anatomical obstruction when lacrimal imaging is utilized.

Long-term Surgical Outcomes in Patients of Centurion Syndrome: A Mystic Etiology of Epiphora in Young.

AIM: To describe the clinical features and long-term outcomes of the medial canthal tendon (MCT) release procedure in patients with Centurion Syndrome (CS). METHODS: We performed a retrospective analysis of the diagnosed patients with CS from July 2013 to December 2019. CS was diagnosed clinically based on the anterior displacement of MCT, anterior dislocation of lacrimal punctum out of tear lake, prominent nasal bridge, beak sign, and synophyrs. All symptomatic patients were advised the anterior limb of MCT release with modified closure of the skin incision. The outcome measures were based on Munk's score (subjective) and the fluorescein dye disappearance test (objective). A minimum postoperative follow-up of 12 months was an inclusion criterion. RESULTS: We studied 22 patients (44 eyes) having a median age of 14.5 years. Anteriorly displaced MCT and lacrimal punctum were noted in 44 eyes (100%), prominent nasal bridge in 20 patients (90.9%), beak sign in 36 eyes (81.8%), and synophyrs in 17 (77.3%) patients. All 44 eyes underwent MCT release with adjunctive punctoplasty (n = 6 eyes) or lower eyelid retractor plication (n = 4 eyes). At a mean follow-up of 12.6 months, 26 eyes (59.1%) showed complete response, i.e., negative FDDT and grade 0 Munk score. Partial response was noted in 14 (31.8%) eyes, i.e., delayed FDDT and reduction of ≥2 grades on Munk score. CONCLUSION: Along with the classic features of CS, beak sign and synophyrs are important diagnostic ophthalmic-facial features of CS. The transverse closure of surgical wounds may provide effective long-term benefits in the medial canthal tendon release procedure.

The Cry of the Third Eye: Exceptionally Rare Location of a Post-Traumatic Acquired Lacrimal Fistula.

PURPOSE: To report an unusual case of an ectopic lacrimal fistula in a setting of a naso-orbito-ethmoid fracture. CASE REPORT: The present case demonstrates a right-sided ectopic lacrimal fistula just below the glabella on the contralateral side on the outer edge of the midline. CT-Dacryocystography demonstrated a large dilated right lacrimal sac with a partly sequestered fundus traversing through the frontal process of the maxilla and frontal bone, close to the skull base and communicating with the fistula. The connection of the fistula with the sac was severed at the superior-most point, and the long fistulous tract was removed using external and endoscopic approaches, followed by endocautery and subsequent dacryocystorhinostomy. Post-operatively, the fistulous opening healed, ostium score was FICI grade 5, and the patient was asymptomatic. CONCLUSION: The case demonstrates multiple surgical challenges while managing an ectopic fistula with a long fistulous tract traversing several bony structures.

Canalicular laceration repair with a novel bicanalicular silicone tube.

PURPOSE: This study aimed to investigate the efficacy and safety of canalicular laceration repair using a novel bicanalicular silicone tube. METHODS: Retrospective and consecutive patients who underwent canalicular laceration repair using novel Runshi-RS bicanalicular silicone stents from January 2020 to February 2021 were included. The stent was placed for 3 months, and patients were followed up for more than 3 months after extubation. Demographics, causes of eyelid injuries, placement time and position of stent, and surgical outcomes at follow-up were recorded. Anatomical success was evaluated by diagnostic probing and irrigation of lacrimal passage, while functional success was evaluated by the patient's subjective symptoms of epiphora. RESULTS: This study included 43 patients with canalicular laceration. The median age was 43 years (3-75 years). The average duration of stent implantation was 12.9 weeks, and the follow-up time was 8.8 months. No complications were observed in any patients during operation and follow-up. After extubation, irrigation of the lacrimal passage in 43 eyes showed no obstruction, and the anatomical success rate was 100%. Overall, 39 patients (90.7%) had no subjective symptoms of epiphora. All patients got good cosmetic results. Furthermore, subgroup classification showed deep laceration group (distance from laceration to punctum>5 mm) accounted for 51.2%, and the functional success rate of the deep laceration group was lower than that of the shallow laceration group. CONCLUSION: Runshi-RS bicanalicular silicone stent achieved good anatomical (100%) as well as functional (90.7%) success and good cosmetic results (100%) in patients with canalicular laceration repair.

Clinical characteristics of lacrimal drainage pathway disease-associated keratopathy.

PURPOSE: To report the clinical characteristics of 13 cases of noninfectious corneal ulceration related to lacrimal drainage pathway disease. METHODS: Medical records of 13 patients with lacrimal drainage pathway disease-associated keratopathy who were examined at Ehime University Hospital between April 2007 and December 2021 were analyzed. RESULTS: The predisposing lacrimal drainage pathway diseases for corneal ulceration were chronic dacryocystitis in seven patients and lacrimal canaliculitis in six patients. The corneal ulcers were located at the peripheral cornea in 10 patients and the paracentral cornea in three patients. All patients indicated few cellular infiltrations of the ulcerated area at the slit-lamp examination. Corneal perforation was found in seven patients. The primary identified organisms were Streptococcus spp. in chronic dacryocystitis and Actinomycetes spp. in lacrimal canaliculitis. All patients showed rapid healing of the epithelial defects after treatment of the lacrimal drainage pathway disease. The mean time elapsed between treatment of the lacrimal drainage pathway disease and re-epithelialization of corneal ulcer was 14.5 ± 4.8 days. CONCLUSION: Lacrimal drainage pathway disease-associated keratopathy may be characterized by peripheral corneal ulcer with few cellular infiltrations, occasionally leading to corneal perforation. Treatment of the lacrimal drainage pathway disease could be the most effective treatment for lacrimal drainage pathway disease-associated keratopathy.

Clinical Findings and Management of Punctal Apposition Syndrome: Rare Cause of Epiphora.

ABSTRACT: The purpose of this study is to evaluate the diagnosis and treatment of punctal apposition syndrome. We retrospectively reviewed the medical records of 2 patients diagnosed with punctal apposition syndrome who underwent lateral tarsal strip procedure. The patients included 1 male and 1 female, with an average age of 76.5 years. Before surgery, both patients had epiphora symptoms with a Munk score of 4 in both eyes. in the primary gaze, it was noted that the upper and lower puncta were appose with each other in both eyes throughout the blinking cycle. On slit lamp examination, there were no keratoconjunctival diseases, and the shape of the puncta were normal. On fluorescein dye disappearance test, grade 3 findings were observed in both eyes of both patients. in dacryos-cintigraphy of the 2 patients, both eyes showed complete obstruction, However, no obstruction of the lacrimal duct system was found in probing and syringing tests. The patient's subjective symptoms improved after patching test. A lateral tarsal strip procedure was performed as a treatment and we obtain satisfactory results. Therefore, punctal apposition syndrome could be 1 of the causes of epiphora.

Conjunctival Fistula After Cosmetic Lateral Canthoplasty.

The authors report the diagnosis and treatment of a patient who developed a conjunctival fistula after undergoing cosmetic lateral canthoplasty. A 34-year-old female patient continued to shed tears in the canthus skin of the left eye for 3 years after undergoing cosmetic lateral canthoplasty. She underwent preoperative fluorescein sodium staining and tear duct probing, which led to a diagnosis of conjunctival fistula. Methylene blue was used as a diagnostic marker and the tear duct probe was positioned for conjunctival fistula resection intraoperatively. Postoperative recovery was good. The causes of tearing of the canthal skin after cosmetic canthal surgery are divided into the following 3 types: lacrimal gland fistula, lacrimal ductal fistula, and conjunctival fistula. The authors further developed its preoperative identification method and treatment.

Persistent epiphora after endonasal ENT surgery: CT dacryography findings.

OBJECTIVES: To analyze postoperative CT dacryography features in patients with persistent epiphora after endonasal surgery. METHODS: We conducted a retrospective study of 76 patients with a history of persistent epiphora after endonasal ENT surgery who underwent CT dacryography between January 2014 and February 2020. Volume acquisition of sub-millimeter sections allowed 2D and 3D reconstructions with virtual endoscopy of the nasosinusal cavities and the lacrimal canal. RESULTS: The postsurgical appearance of the nasosinusal cavities revealed a middle meatal antrostomy in 37% of cases, less frequently an ethmoidectomy or an inferior meatal antrostomy, sometimes completed by a middle or inferior turbinectomy. In thirty-five patients (46%), the lacrimal canal was distant from the endonasal ENT procedure. Epiphora was related to mucosal hypertrophy, constricting all or part of the lacrimal canal. Thirty-three patients (43%) showed changes in the lacrimal canal at the surgical site. In the inferior meatus, the nasolacrimal orifice was sometimes involved in the inferior turbinectomy or meatotomy, but most of the time, in the middle meatus, resection of the uncinate process prior to ethmoidectomy or middle meatotomy was associated with a lesion of the contiguous lacrimal canal. CONCLUSION: As a rare cause of persistent tearing, involvement of the nasolacrimal duct at the edge of the endonasal ENT surgery highlights the importance of intraoperative localization of the nasolacrimal duct before resection of the uncinate process or the inferior turbinate, ideally predicted by preoperative CT imaging.

Bilateral lacrimal gland disease: clinical features and outcomes.

BACKGROUND: Patients with bilateral lacrimal gland disease are a unique subset of patients where there is a paucity of literature. This presentation often represents systemic disease or malignancy and can cause diagnostic difficulties. We aim to describe the diagnoses and features of bilateral lacrimal gland disease. METHOD: Retrospective multi-centre case series involving 115 patients with bilateral lacrimal gland disease from 1995 to 2020. RESULTS: 115 patients were included. Their ages ranged from 9 to 85 (mean 47.3 years) with a female predominance (73, 63.5%). The most common category of diagnosis was inflammatory (69, 60%) followed by lymphoproliferative (23, 20%), structural (17, 14.8%) and other conditions (6, 5.2%). The five most common specific diagnoses were IgG4 related disease (20, 17.4%) and idiopathic orbital inflammatory disease (20, 17.4%), lymphoma (16, 13.9%), lacrimal gland prolapse (13, 11.3%), and sarcoidosis (11, 9.6%). Corticosteroid treatment was used most commonly (29, 25.2%) followed by observation (25, 21.7%). At last follow up, the majority of patients had complete resolution, significant improvement with mild residual disease or stable disease without further progression (104, 90.4%). CONCLUSION: Bilateral lacrimal disease may be due to a range of aetiologies, most of which are systemic. The most common are inflammatory and lymphoproliferative conditions. Due to the wide range of aetiologies of bilateral lacrimal gland disease, it is extremely difficult to accurately determine a cause based on clinical findings alone, highlighting the vital role of lacrimal gland biopsy in patients presenting with bilateral lacrimal gland disease.

Salvage of impending rhinostomy failure after dacryocystorhinostomy with office-based microdebrider treatment.

PURPOSE: This article is to introduce office-based salvage revision of impending rhinostomy failure after endoscopic dacryocystorhinostomy (EN-DCR), using a microdebrider. METHODS: The authors conducted retrospective medical chart review of 27 eyes of 26 patients who underwent microdebrider treatment for impending rhinostomy failure in an office setting. After local anesthesia, obstructive soft tissue, interfering with ostium function (granuloma, cicatrization, synechia), was treated with a microdebrider (Osseoduo s120, Bien-Air Surgery, Le Noirmont, Switzerland) within 6 months after primary EN-DCR. Anatomical improvement and functional relief of epiphora were evaluated after revision. RESULTS: The causes of impending rhinostomy failure were granuloma formation (17/27 eyes, 63.0%), cicatrization (8/27 eyes, 29.6%), and synechial formation (2/27 eyes, 7.4%). The surgery did not exceed 5 min in all cases, and partial damage to pre-placed silicone tubes occurred in the first two cases (7.4%). Salvage revision resulted in anatomical success in all eyes, based on patent syringing and a positive functional endoscopic dye test. All cases showed improvement of epiphora after revision surgery. CONCLUSIONS: Office-based salvage revision using a microdebrider provided effective management of impending rhinostomy failure during early follow-up period after primary EN-DCR. It enabled prompt management of excessive wound healing interfering with ostium function, while performing the routine postoperative nasal debridement.

Tear Trough Malar Implant Penetrating Lacrimal Sac Causing Lacrimal Obstruction and Epiphora: Case Report and Review.

Tear trough implantation may be associated with a number of well-reported complications. To our knowledge, penetration of the lacrimal sac has never been reported as a complication of malar or tear trough implants. We report a case of lacrimal sac penetration discovered at the time of endoscopic dacryocystorhinostomy surgery in a patient who developed epiphora soon after the tear trough implant was placed.
