Presumed Lacrimal Gland Pleomorphic Adenoma With Extensive Ossification and Necrosis.

Calcification within pleomorphic adenomas of the lacrimal gland is well recognized but uncommon, being seen more readily in lacrimal gland carcinomas. Bony formation, ossification, in pleomorphic adenomas of the lacrimal glands is even rarer. Together with extensive sclerosis, or "coagulative necrosis," ossification and necrosis should alert the clinician to the risk of malignant transformation. However, both can mimic carcinomatous change, leading to misinterpretation of malignancy in an otherwise benign lacrimal gland neoplasm. We present 2 case reports of patients with clinically presumed pleomorphic adenomas of the lacrimal gland whose histopathology demonstrated lacrimal gland ossification and necrosis without features of malignancy or invasive disease.

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.

Primary Lacrimal Sac Tumors with Extension into Vicinity: Outcomes with Endoscopy-Assisted Modified Weber-Ferguson's Approach.

PURPOSE: To evaluate the outcomes of endoscopy-assisted modified Weber-Ferguson's approach in the management of primary lacrimal sac tumors with extension into the neighboring tissues. METHODS: A retrospective interventional study was performed on all patients with lacrimal sac tumors treated with the endoscopy-assisted modified Weber-Ferguson approach between January 2010 and June 2022 at the Shanghai Ninth People's Hospital, China. Data assessed include demographics, clinical presentations, imaging features, surgical techniques, histopathology, adjuvant modalities of management, complications, and outcomes. RESULTS: A total of 13 patients were included in the analysis. Epiphora and palpable mass lesion were the presenting complaint in 84.6% (11/13) of the patients. Nearly half of the patients (46.1%, 6/13) were misdiagnosed as lacrimal duct obstruction. All the lacrimal sac tumors in the present series showed uneven enhancement on T1-weighted MRI imaging. Postoperatively, 84.6% (11/13) patients recovered well with excellent esthetics and were disease-free after a mean follow-up of 58.6 months. Two patients who underwent additional exenteration developed recurrence and succumbed (at 41 and 96 months follow up) while they were on palliative chemoradiation. CONCLUSION: The endoscopic-assisted modified Weber-Fergusson surgical approach is effective in providing better visibility and accessibility to lacrimal sac tumors with extension into neighboring tissue.

Comparing the diagnostic accuracy of MR dacryocystography (MRD) and dacryoscintigraphy (DSG) in NLDO-related acquired epiphora.

PROPOSE: This study aimed to compare the diagnostic accuracy of MR dacryocystography (MRD) and dacryoscintigraphy (DSG) in the diagnosis of acquired epiphora related to NLDO. A total of 15 patients with acquired epiphora and suspected NLDO were included in this study. METHODS: All patients underwent MRD and DSG examinations. MRD was performed using a 3-Tesla magnetic resonance imaging (MRI) scanner, while DSG involved injection of a radiotracer into the lacrimal drainage system followed by DSG. The results of both imaging methods were compared with the reference standard that was a combination of clinical examination findings and surgical exploration. RESULTS: The results of this study showed that no abnormal findings were observed in MR-DCG in patients before the Valsalva maneuver. However, after the Valsalva maneuver, stenosis/obstruction at the canal surface was observed in all 15 patients diagnosed by DSG, giving a sensitivity of 100% for canal stenosis. Moreover, the results revealed that among these 15 patients, 9 showed stenosis or simultaneous obstruction at the level of the canal and lacrimal sac, but MR-DCG showed these lesions in only 9 patients, giving a sensitivity of 60%. The specificity of MRD and DSG were 85% and 76.7%, respectively. There was a statistically significant difference in the sensitivity of MRD and DSG (p < 0.05). CONCLUSION: This study demonstrated that MRD has a higher diagnostic accuracy in the diagnosis of acquired epiphora associated with NLDO compared to DSG. MRD showed significantly higher sensitivity and specificity than DSG. Therefore, MRD can be considered as the preferred imaging modality in the diagnosis of acquired epiphora due to NLDO. By accurately identifying the underlying cause of NLDO, MRD can help determine the most appropriate treatment approach for patients and lead to better outcomes.

Epstein-Barr Virus-Associated Acute Dacryocystic Retention.

Epstein-Barr virus (EBV) associated dacryocystic retention presents with an acute swelling in the lacrimal sac area with epiphora and lymphadenopathy. The patient would usually have a preceding history of infectious mononucleosis with clinical features of fever, pharyngitis, preauricular and cervical lymphadenopathy, hepatosplenomegaly, subclinical hepatitis, nausea, and palatine petechiae. The present case is of a 3-year-old child who presented with a sudden painless swelling in the lacrimal sac region with epiphora. Investigations and a biopsy helped in establishing the diagnosis of EBV-associated dacryocystic retention which resolved completely with conservative management.

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.

A Pilot Study of Dynamic Magnetic Resonance Dacryocystography Imaging to Assess Functional Epiphora.

OBJECTIVE: To evaluate dynamic magnetic resonance dacryocystography (MRDCG) in eyes with functional epiphora. METHODS: We included prospective eyes with epiphora if no alternative cause was found on clinical examination, were patent on syringing, had no obstruction or stenosis on DCG, and had an abnormal DSG. MRDCG was performed to qualitatively assess for block or patency and quantitatively measure tear transit time. We compared measurements to asymptomatic fellow eyes and to historical reference values from asymptomatic eyes. RESULTS: We included 26 symptomatic eyes of 19 patients (median age 63 years). There was a block on MRDCG in 18 (69%) eyes and patency in 8 (31%) eyes. The block occurred at the sac-nasolacrimal duct (NLD) junction in 9 (50%), proximal NLD in 5 (28%), mid-NLD in 1 (5.6%), and distal NLD in 1 (5.6%) eye(s). No contrast was observed in the lacrimal system in two eyes. For eyes patent on MRDCG, median times to the sac, NLD, inferior meatus, first 25%, and first 50% of the fundus-to-nose distance (FND) were 22, 54, 118, 34, and 84 s, respectively. Times to the sac, NLD, and to fill the first 25% and 50% of the FND were significantly longer than historical values from asymptomatic lacrimal systems (p = 0.017, 0.050, 0.035, 0.017, respectively). CONCLUSION: MRDCG shows a high rate of block in functional epiphora. However, DSG and MRDCG results may not always correlate. The improved temporal resolution of this emerging modality may be advantageous in the critical first 2 min of tear transit.

[Concrements of the lacrimal apparatus]. / Konkremente des Tränenapparates.

Concrements of the lacrimal apparatus, known as dacryoliths, can occur at different localizations and can cause a variety of symptoms. A common clinical sign is chronic inflammation, possibly exhibiting acute exacerbation. Based on a literature review and descriptive clinical cases with histopathological correlations, this contribution summarises the most important information concerning epidemiology, aetiopathogenesis, composition, histology, and therapy of lacrimal concrements. Furthermore, factors known to affect lacrimal lithogenesis are addressed. Concrements of the lacrimal gland cause a swelling at the lateral canthus. With only mild pain, this manifests as circumscribed conjunctival hyperaemia. Histologically, the gland tissue is characterised by acute-erosive to chronic inflammation. The concrements consist of amorphic material. Inflammatory infiltration is dominated by neutrophil granulocytes. Canalicular concrements are highly correlated with chronic canaliculitis. Besides epiphora, patients present with purulent discharge at the affected canaliculus. Actinomyces are frequently found inside these deposits and form drusen-like formations. The surrounding tissue reacts with plasma-cellular and granulocytic inflammation. Dacryoliths (concrements of the lacrimal sac) are associated with dacryocystitis, whereby acute and chronic types are common. Stones can be found in up to 18% of patients undergoing dacryocystorhinostomy or dacryoendoscopy. Preoperative diagnostic testing is challenging, as many lacrimal sac stones cannot be reliably visualised by diagnostic procedures. Recurring episodes of epiphora, mucopurulent discharge, and dacryocystitis are common indicators of dacryoliths. Lacrimal syringing is often possible and shows that total blockage is not present. Histology of the lacrimal mucosa reveals lymphocytic infiltration and submucosal fibrosis. The immediate vicinity of the dacryoliths shows acute inflammation. Therapy consists of stone extraction and improving lacrimal drainage, as the latter is recognised as the main risk factor for dacryolith formation.

An Unusual Case of Lacrimal Gland Dacryops in a 10-Year-Old Child.

Lacrimal gland dacryops are an unusual type of benign epithelial neoplasm. Most of the literature refers to dacryops of the lacrimal palpebral lobe, with orbital lobe involvement less frequent. The authors report a case of dacryops in a 10-year-old child involving the orbital lobe of the lacrimal gland. [J Pediatr Ophthalmol Strabismus. 2023;60(6):e79-e82.].

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.

[Watery eyes: diagnostic and therapeutic considerations]. / Tranende ogen.

Tear complaints can arise from either an increased tear production or from a disturbed tear drainage. Increased tear production from the lacrimal gland is a neuroregulated response to a dried out or irritated ocular surface. Dryness often results from a reduced quality of the tear film, but can also be caused by eyelid malposition with increased globe exposure. Impaired tear drainage usually occurs when the lacrimal drainage system is blocked at the level of the ductus nasolacrimalis, the canaliculi or the lacrimal punctae. Anatomical knowledge of the lacrimal system is necessary to distinguish between the different causes. Using cases and illustrations, we provide insight into the diagnostic considerations for a patient with a watery eye.

Supernumerary lacrimal puncta: case series and review of the literature.

We report a case series of supernumerary puncta-canaliculi, a very rare congenital anomaly, and describe different clinical presentations and new treatment options. This is a retrospective chart review of patients diagnosed with supernumerary lacrimal puncta during the time between June 2015 and December 2021 at the Research Institute of Ophthalmology, Giza, Egypt. Four patients (two females and two males) with a mean presenting age of 54 ± 14 years had unilateral double puncta. Of those four patients, three had double puncta on the right lower eyelid whereas one had double puncta on the left upper and lower eyelid. In one of the three patients, the double puncta anomaly was an incidental finding, and the patient was asymptomatic. The other three patients had associated epiphora. All four patients were found to have patent double puncta with no mechanical obstruction. No surgical interventions were necessary for all four patients as one resolved after discontinuing the topical eye drops. Another patient resolved after the diagnostic probing of the puncta, and the third asymptomatic patient required no interventions. Epiphora in the fourth patient resolved with botulinum toxin injection in the lacrimal gland. Accessory lacrimal puncta can present in patients as an incidental asymptomatic finding or patients may present with epiphora. Patients who present with unilateral epiphora, dry eye, or canaliculitis should be carefully evaluated with a detailed slit-lamp examination using lid eversion to appreciate potentially easily missed supernumerary lacrimal puncta.

Don't forget Allgrove syndrome in adult patients as a bulbar-ALS mimicker.

INTRODUCTION: Allgrove syndrome is a genetic disorder characterized by a multisystem involvement manifesting mainly in childhood with esophageal achalasia, adrenal insufficiency, and alacrima. Associated neurological manifestations are frequent in patients with late-onset forms and include peripheral, central, and autonomic dysfunction. The definitive diagnosis remains genetic, but neurological symptoms/signs could be a relevant clue for the diagnosis. DISCUSSION: This syndrome is rare, but it is not impossible for it to occur in adults, so all neurologists must be alert. Moreover, in this regard, neurological symptoms can sometimes be very similar to those of motor neuron disease patients, so that, although rare, Allgrove syndrome may also enter into the differential diagnosis with the bulbar variant of amyotrophic lateral sclerosis. Nevertheless, attention to extra-neurological symptoms must remain high as these play an equally important role in reaching the diagnosis. CASE REPORT: Here we present the case of a patient with some peculiarities that are onset at an advanced age, genetic confirmation of the diagnosis, and prominent neurological involvement, which also opens the differential diagnosis to amyotrophic lateral sclerosis.

[Congenital anomalies in lacrimal drainage]. / Angeborene Fehlbildungen der ableitenden Tränenwege.

Congenital dacryostenosis is the most common reason for ophthalmic consultation in childhood. It is most often caused by persisting of Hasner's membrane. However, congenital malformations of the lacrimal drainage system can also occur in rare cases. In the area of the proximal lacrimal drainage system, supernumerary lacrimal puncta and canaliculi can arise as well as diverticula, fistula, and atresia. The distal lacrimal drainage system can be affected by fistulas, amniotoceles, and cysts. Association of lacrimal malformations with congenital systemic diseases is reported in about 10% of cases. Depending on the severity of the symptoms, surgical rehabilitation can be performed, and endoscopic procedures and modern lacrimal drainage intubation systems may be employed.

[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.
