Abstract
OBJECTIVE Dry eye disease (DED) is a multifactorial disease involving the tears and ocular surface. It impacts a patient's quality of life (QoL) and ability to perform daily activities. This study assessed the burden of self-reported DED among adults in eight European countries. DESIGN Online cross-sectional survey. SETTING General population in France, Italy, Germany, Greece, the Netherlands, Portugal, Spain and Sweden. PARTICIPANTS Adults aged ≥18 years with (n=6084) and without (n=6161) self-reported DED were recruited via emails and screened. MAIN OUTCOME MEASURES All participants completed National Eye Institute Visual Function Questionnaire-25 (NEI-VFQ-25) and EuroQol-5 Dimension-5 Level Questionnaire (EQ-5D-5L). All DED participants completed the Eye Dryness Score (EDS) Visual Analogue Scale, and Ocular Comfort Index and Work Productivity and Activity Impairment Questionnaire: Specific Health Problem questionnaires. In addition, half of the respondents with DED completed Survey A (Impact of Dry Eye on Everyday Life) and the other half completed Survey B (Standard Patient Evaluation of Eye Dryness Questionnaire) and Dry Eye Questionnaire-5. RESULTS Participants with self-reported DED had lower functional vision and lower overall health status than participants without self-reported DED as measured by the NEI-VFQ and EQ-5D-5L, respectively.Increasing self-reported DED severity as measured by the EDS was shown to correspond with worse symptom severity/frequency, lower functional vision, higher impact on work productivity, daily activities and QoL. CONCLUSION This study showed that patients' reported burden of self-reported DED was similar across the eight European countries. Those with self-reported DED reported lower health status and functional vision compared to those without self-reported DED and these parameters worsen with increasing disease severity.

Role of corneal nerves in ocular surface homeostasis and disease. Acta Ophthalmol 2019; 97:137-145.

Abstract
Corneal nerves are key components of the physiological system that controls ocular surface homeostasis. The cornea is primarily innervated by the ophthalmic branch of the trigeminal nerves (cranial nerve V), which distend bilaterally from the pons. The nasociliary branch (afferent) of the ophthalmic nerve is sensory for cornea, eyelid and conjunctiva. These nerve fibres play a role in sensing temperature, chemical and mechanical stimuli, and pain, whereas, branches of the facial nerve (cranial nerve VII) contain motor nerves that control blinking and autonomic (sympathetic and a paucity of parasympathetic) fibres that stimulate tear production and secretion via feedback loops between the ocular surface, lacrimal glands and brain. Disruption of these nerves with interruption of neural feedback loops between the ocular surface and lacrimal glands can lead to corneal diseases such as dry eye disease (DED) and neurotrophic keratopathy (NK). Inversely, hypersensitivity of the nerve fibres and/or dysregulation of pain-controlling nervous centres may lead to neuropathic pain. Recently, medications that specifically target regeneration of corneal nerves have started to become available - and considering the high prevalence of diseases associated with corneal nerve dysfunction, these agents promise to fulfil a hitherto important unmet need. In this review, we explore the physiology of corneal nerves, the pathology of corneal nerve diseases and how these relate to neuropathic pain, NK and DED. We also discuss what novel treatments may be useful against diseases involving corneal nerves.

Abstract
Glaucoma therapy-related ocular surface disease (OSD) is a serious pathology with a broad spectrum of insidious clinical presentations and complex pathogenesis that undermines long-term glaucoma care. Preservatives, especially benzalkonium chloride (BAK), contained in topical intraocular pressure-lowering medications frequently cause or aggravate OSD in glaucoma. Management of these patients is challenging, and to date often empirical due to the scarcity of controlled long-term clinical trials. Most of the available data are extracted from case series and retrospective analysis. Preservative-free prostaglandins and prostaglandin/timolol fixed combinations are novel options developed to remove the harmful impact of preservatives, especially BAK, upon ocular tissues. Based on what is currently known on the value of preservative-free antiglaucoma therapies it is tempting to speculate how these new therapies may affect the future medical management of all glaucoma patients. This article provides a comprehensive and critical review of the current literature on preservative-free prostaglandins and preservative-free prostaglandin/timolol fixed combinations.

Abstract
Dry eye disease (DED) is a common condition with signs and symptoms that vary depending on a wide range of environmental factors to which people are exposed in their daily lives. Factors such as variable temperature, airflow velocity, relative humidity, seasonality, and pollutants can alter the rate of tear film evaporation, improving or exacerbating symptoms of DED. Results from currently available clinical tests do not always correlate well with patient-reported symptoms, and the continually changing environment and variability in DED symptoms present challenges for the design and conduct of clinical trials. Controlled adverse environment chambers allow standardization of temperature, humidity, and airflow and may minimize potential confounding factors in clinical investigations. Their use can promote accurate study of the pathophysiology of DED, discovery of disease biomarkers, and assessment of the effect of various therapeutic approaches on patients' symptoms. Controlled adverse environment chambers have been used to simulate indoor surroundings such as airplane cabins and to test their effects on contact lens wearers. This review summarizes how these chambers may be useful for the development, approval, and differentiation of potential new treatments for DED.

Abstract
PURPOSE Intravenous glucocorticoids (ivGCs) given as 12-weekly infusions are the first-line treatment for moderate-to-severe and active Graves' orbitopathy (GO), but they are not always effective. In this study, we evaluated whether response at 6 weeks correlated with outcomes at 12 (end of intervention) and 24 (follow-up) weeks, particularly in patients initially unresponsive. METHODS Our database (Bartalena et al. J Clin Endocrinol Metab 97:4454-4463, 10), comprising 159 patients given three different cumulative doses of methylprednisolone (2.25, 4.98, 7.47 g) was analyzed, pooling data for analyses. Responses at 6 weeks were compared with those at 12 and 24 weeks using three outcomes: overall ophthalmic involvement [composite index (CI)]; quality of life (QoL); Clinical Activity Score (CAS). Responses were classified as "Improved", "Unchanged", "Deteriorated", compared to baseline. RESULTS Deteriorated patients at 6 weeks for CI (n = 8) remained in the same category at 12 weeks and 7/8 at 24 weeks. Improved patients at 6 weeks for CI (n = 51) remained in the same category in 63% and 53% of cases at 12 and 24 weeks, respectively. Unchanged patients at 6 weeks (n = 100) eventually improved in 28% of cases (CI), 58% (CAS), 32% (QoL). There was no glucocorticoid dose-dependent difference in the influence of early response on later outcomes. CONCLUSIONS Patients who deteriorate at 6 weeks after ivGCs are unlikely to benefit from continuing ivGCs. Patients unresponsive at 6 weeks still have a significant possibility of improvement later. Accordingly, they may continue ivGC treatment, or, alternatively, possibly stop ivGCs and be switched to a second-line treatment.

Emerging strategies for the diagnosis and treatment of meibomian gland dysfunction: Proceedings of the OCEAN group meeting. Ocul Surf 2017; 15:179-192. [PMID: 28132878 DOI: 10.1016/j.jtos.2017.01.006] [Citation(s) in RCA: 91] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2016] [Revised: 01/20/2017] [Accepted: 01/23/2017] [Indexed: 01/01/2023]
Abstract
Meibomian gland dysfunction (MGD) is a common and chronic disorder that has a significant adverse impact on patients' quality of life. It is a leading cause of evaporative dry eye disease (DED), as meibomian glands play an important role in providing lipids to the tear film, which helps to retard the evaporation of tears from the ocular surface. MGD is also often present in conjunction with primary aqueous-deficient DED. Obstructive MGD, the most commonly observed type of MGD, is the main focus of this article. MGD is probably caused by a combination of separate conditions: primary obstructive hyperkeratinization of the meibomian gland, abnormal meibomian gland secretion, eyelid inflammation, corneal inflammation and damage, microbiological changes, and DED. Furthermore, skin diseases such as rosacea may play a part in its pathology. Accurate diagnosis is challenging, as it is difficult to differentiate between ocular surface diseases, but is crucial when choosing treatment options. Ocular imaging has advanced in recent years, providing ophthalmologists with a better understanding of ocular diseases. This review presents a literature update on the 2011 MGD workshop and an optimized approach to accurate diagnosis of MGD using currently available methods and tests. It also outlines the emerging technologies of interferometry, non-contact meibography, keratography and in vivo confocal laser microscopy, which offer exciting possibilities for the future. Selected treatment options for MGD are also discussed.

Revisiting the vicious circle of dry eye disease: a focus on the pathophysiology of meibomian gland dysfunction. Br J Ophthalmol 2016; 100:300-6. [PMID: 26781133 PMCID: PMC4789719 DOI: 10.1136/bjophthalmol-2015-307415] [Citation(s) in RCA: 295] [Impact Index Per Article: 36.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2015] [Revised: 10/29/2015] [Accepted: 11/28/2015] [Indexed: 12/29/2022]
Abstract
Meibomian gland dysfunction (MGD) is the most frequent cause of dry eye disease (DED). Eyelid inflammation, microbial growth, associated skin disorders as well as potentially severe corneal complications culminate to make MGD a complex multifactorial disorder. It is probable that MGD is a heterogeneous condition arising from any combination of the following five separate pathophysiological mechanisms: eyelid inflammation, conjunctival inflammation, corneal damage, microbiological changes and DED resulting from tear film instability. The pathogenesis of both MGD and DED can be described in terms of a 'vicious circle': the underlying pathophysiological mechanisms of DED and MGD interact, resulting in a double vicious circle. The MGD vicious circle is self-stimulated by microbiological changes, which results in increased melting temperature of meibum and subsequent meibomian gland blockage, reinforcing the vicious circle of MGD. Meibomian gland blockage, dropout and inflammation directly link the two vicious circles. MGD-associated tear film instability provides an entry point into the vicious circle of DED and leads to hyperosmolarity and inflammation, which are both a cause and consequence of DED. Here we propose a new pathophysiological scheme for MGD in order to better identify the pathological mechanisms involved and to allow more efficient targeting of therapeutics. Through better understanding of this scheme, MGD may gain true disease status rather than being viewed as a mere dysfunction.

Abstract
Dry eye disease (DED), a multifactorial disease of the tears and ocular surface, is common and has a significant impact on quality of life. Reduced aqueous tear flow and/or increased evaporation of the aqueous tear phase leads to tear hyperosmolarity, a key step in the vicious circle of DED pathology. Tear hyperosmolarity gives rise to morphological changes such as apoptosis of cells of the conjunctiva and cornea, and triggers inflammatory cascades that contribute to further cell death, including loss of mucin-producing goblet cells. This exacerbates tear film instability and drives the cycle of events that perpetuate the condition. Traditional approaches to counteracting tear hyperosmolarity in DED include use of hypotonic tear substitutes, which have relatively short persistence in the eye. More recent attempts to counteract tear hyperosmolarity in DED have included osmoprotectants, small organic molecules that are used in many cell types throughout the natural world to restore cell volume and stabilize protein function, allowing adaptation to hyperosmolarity. There is now an expanding pool of clinical data on the efficacy of DED therapies that include osmoprotectants such as erythritol, taurine, trehalose and L-carnitine. Osmoprotectants in DED may directly protect cells against hyperosmolarity and thereby promote exit from the vicious circle of DED physiopathology.

Abstract
BACKGROUND Optimal doses of i.v. glucocorticoids for Graves' orbitopathy (GO) are undefined. METHODS We carried out a multicenter, randomized, double-blind trial to determine efficacy and safety of three doses of i.v. methylprednisolone in 159 patients with moderate to severe and active GO. Patients were randomized to receive a cumulative dose of 2.25, 4.98, or 7.47 g in 12 weekly infusions. Efficacy was evaluated objectively at 12 wk by blinded ophthalmologists and subjectively by blinded patients (using a GO specific quality of life questionnaire). Adverse events were recorded at each visit. RESULTS Overall ophthalmic improvement was more common using 7.47 g (52%) than 4.98 g (35%; P = 0.03) or 2.25 g (28%; P = 0.01). Compared with lower doses, the high-dose regimen led to the most improvement in objective measurement of ocular motility and in the Clinical Activity Score. The Clinical Activity Score decreased in all groups and to the least extent with 2.25 g. Quality of life improved most in the 7.47-g group, although not reaching statistical significance. No significant differences occurred in exophthalmos, palpebral aperture, soft tissue changes, and subjective diplopia score. Dysthyroid optic neuropathy developed in several patients in all groups. Because of this, differences among the three groups were no longer apparent at the exploratory 24-wk visit. Major adverse events were slightly more frequent using the highest dose but occurred also using the lowest dose. Among patients whose GO improved at 12 wk, 33% in the 7.47-group, 21% in the 4.98-group, and 40% in the 2.25-group had relapsing orbitopathy after glucocorticoid withdrawal at the exploratory 24-wk visit. CONCLUSIONS The 7.47-g dose provides short-term advantages over lower doses. However, this benefit is transient and associated with slightly greater toxicity. The use of a cumulative dose of 7.47 g of methylprednisolone provides short-term advantage over lower doses. This may suggest that an intermediate-dose regimen be used in most cases and the high-dose regimen be reserved to most severe cases of GO.

Abstract
BACKGROUND Orbital decompression is an established procedure for the management of exophthalmos and visual rehabilitation from optic neuropathy in cases of thyroid eye disease. Numerous procedures for removal of orbital bony wall, fat or a combination of these for a variety of indications in different stages of the disease have been well reported in the medical literature. However, the relative effectiveness and safety of these procedures in relation to the various indications remains unclear. OBJECTIVES To review current published evidence for the effectiveness of surgical orbital decompression for disfiguring proptosis in adult thyroid eye disease and summa rise information on possible complications and the quality of life from the studies identified. SEARCH METHODS We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2011, Issue 10), MEDLINE (January 1950 to October 2011), EMBASE (January 1980 to October 2011), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com) and ClinicalTrials.gov (http://clinicaltrials.gov). There were no date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 6 October 2011. We searched oculoplastic textbooks, conference proceedings from the European and American Society of Ophthalmic Plastic and Reconstructive Surgery (ESOPRS, ASOPRS), European Ophthalmological Society (SOE), the Association for Research in Vision and Ophthalmology (ARVO) and American Academy of Ophthalmology (AAO) for the years 2000 to 2009 to identify relevant data. We attempted to contact researchers who are active in this field for information about further published or unpublished studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) with no restriction on date or language comparing two or more surgical methods for orbital decompression with removal of bony wall, orbital fat or a combination of both for disfiguring proptosis or comparison of surgical techniques with any form of medical decompression. DATA COLLECTION AND ANALYSIS Each review author independently assessed study abstracts identified from the electronic and manual searches. Author analysis was then compared and full papers for appropriate studies were obtained according to the inclusion criteria. Disagreements between the authors were resolved by discussion. MAIN RESULTS We identified two randomised trials eligible for inclusion in the review. There was significant variability between the trials for interventions, methodology and outcome measures and therefore meta-analysis was not performed. One study suggested that the transantral approach and endoscopic transnasal technique had similar effects in reducing exophthalmos but that the endoscopic approach may be safer, relating to fewer complications. This study had short-term follow-up and lacked information on our primary outcome (success or failure of treatment). The second study provided evidence that intravenous steroids may be superior to primary surgical decompression in the management of compressive optic neuropathy requiring less secondary surgical procedures, although it relates more frequently to transient side effects. This study was weakened by a small sample size. Until more credible evidence is available recommendations as to best treatment cannot be reliably made. AUTHORS' CONCLUSIONS A single study showed that the transantral approach for orbital decompression was related to more complications than the endoscopic transnasal technique which is preferred by Ear, Nose and Throat (ENT) surgeons, usually as an adjunctive procedure. Intravenous steroids were reported in a single trial to be the most efficient intervention for dysthyroid optic neuropathy. The majority of published literature on orbital decompression for thyroid eye disease consists of retrospective, cohort, or case series studies. Although these provide useful descriptive information, clarification is required to show the relative effectiveness of each intervention for various indications.The two RCTs reviewed are not robust enough to provide credible evidence to our understanding of current decompressive surgery and to support recommendations for clinical practice. There is evidence from currently available uncontrolled studies that removal of the medial and lateral wall (balanced decompression) with or without fat removal may be the most effective surgical method related to only a few complications.There is a clear need for randomised studies evaluating the balanced two-wall, three-wall and orbital fat decompression techniques. Comparison with other surgical techniques for orbital decompression or with immunosuppression in cases of compressive optic neuropathy would also be important. These studies should primarily address the reduction of exophthalmos, disease severity, complication rates, quality of life and cost of the intervention.

Abstract
BACKGROUND Entropion is a condition in which the eyelid margin turns in against the eyeball. Involutional or senile entropion is one of the most common lower lid malpositions in the elderly. The interventions described and currently used for the treatment of this condition are surgical in nature, although non-surgical temporary medical treatment for the early stages of entropion has also been reported. The relative effectiveness of these interventions has not yet been resolved. OBJECTIVES To examine the effect of interventions for involutional entropion and to assess whether any method is superior to any other. SEARCH METHODS We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (The Cochrane Library 2011, Issue 10), MEDLINE (January 1950 to November 2011), EMBASE (January 1980 to November 2011), the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com),ClinicalTrials.gov (http://clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). There were no date or language restrictions in the electronic searches for trials. The electronic databases were last searched on 2 November 2011. We also searched oculoplastic textbooks, conference proceedings from the European and American Society of Ophthalmic Plastic and Reconstructive Surgery (ESOPRS, ASOPRS), European Ophthalmological Society (SOE), the Association for Recearch in Vision and Ophthalmology (ARVO) and American Academy of Ophthalmology (AAO) for the years 2000 to 2009 to identify relevant data. We attempted to contact researchers who are active in this field for information about further published or unpublished studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) with no restriction on date or language comparing two or more surgical methods for correction of involutional lower eyelid entropion in people older than 60 years of age with involutional lower lid entropion. DATA COLLECTION AND ANALYSIS Each review author independently assessed study abstracts identified from the electronic and manual searches. Author analysis was then compared and full papers for appropriate studies were obtained according to the inclusion criteria. Disagreements between the authors were resolved by discussion. MAIN RESULTS We identified one RCT which met our inclusion criteria and was included in this review. Sixty-three participants with primary involutional lower eyelid entropion were randomised to everting sutures alone or everting sutures with a lateral tarsal strip. Eight participants were lost to follow-up. The trial indicates that the combined procedure for horizontal and vertical eyelid tightening in the form of everting sutures and lateral tarsal strip is highly curative for involutional entropion compared to vertical tightening in the form of everting sutures alone. The superiority of the combined approach is also supported by many good quality uncontrolled studies on specific surgical procedures but these were not included in the analysis as they were not part of the inclusion criteria. AUTHORS' CONCLUSIONS A single RCT showed that the combination of horizontal and vertical eyelid tightening with everting sutures and lateral tarsal strip is highly efficient for entropion compared to vertical tightening with everting sutures alone. Retrospective case series studies also support the combined surgical repair but details from these studies on specific surgical techniques cannot be included in the analysis.Evidence from a single RCT is unlikely to change clinical practice and thus it is still our view that there is a clear need for more randomised studies comparing two or more surgical techniques for entropion surgery addressing the recurrence and complications rate.

Abstract
Kaposi's sarcoma is an uncommon endothelial malignant tumor, first described by Moricz Kaposi in 1872. It is commonly encountered in patients with acquired immunodeficiency syndrome (AIDS), immunosuppression or organ transplantation. Conjunctival Kaposi's sarcoma is a rare tumor, mostly in patients with AIDS. We present a selected case with a superior bulbar conjunctival lesion in a patient who is HIV negative and immunocompetent, with an unremarkable general medical history. The lesion was surgically excised with no adjunctive treatment, and histological examination confirmed the diagnosis. There was no recurrence or metastasis 5 years after surgery.

Abstract
Thyroid eye disease manifests as orbital inflammation resulting in extraocular muscle enlargement and orbital fat proliferation. This causes exophthalmos, ocular motility impairment and eyelid retraction. Numerous surgical procedures have been introduced for correction of exophthalmos by removal of bony walls. The limited success and high complication rate of the early methods lead to the evolution of an alternative procedure for reduction of retrobulbar volume by removal of intraorbital fat. The indications for this procedure extended from orbital decompression to compressive optic neuropathy with satisfactory results. The moderate complication rate and the fact that orbits with predominant muscle enlargement respond purely to this technique leads to the evolution of a combined procedure with orbital fat removal and bony wall decompression. The scattered published evidence comprising retrospective case series highlights the need for prospective controlled clinical trials in order to improve patient care and clinical practice.

Abstract
Purpose: To describe a modification of the retrograde intubation dacryocystorhinostomy (DCR) in patients with proximal canalicular obstruction. Materials and methods: Interventional case report of a 43-year-old female with a nine-month history of left epiphora following a road traffic accident involving the proximal lower canaliculus. An external DCR approach was performed. Following the creation of a lower canalicular pseudopunctum, the O’Donoghue silicone stent was introduced through the common ostium, out through the pseudopunctum of the lower canaliculus, and returned through the punctum of the normal upper canaliculus down through the common ostium into the nose. Results: The patient experienced complete resolution of symptoms and on her last follow-up, two years later, her lower canaliculus was patent to syringing. Conclusion: This modification of the retrograde intubation DCR is an effective technique which decreases the intraoperative time needed to insert the tubes and minimises further trauma to the newly created punctal area.

Abstract
We present the reconstructive challenge after excision of a large periocular tumour in a patient who needed early visual rehabilitation. The periocular full thickness deficit of his only sighted eye was reconstructed with a combination of periocular myocutaneous flaps and a free buccal mucosal graft. Adequate functional and cosmetic results with early visual rehabilitation were achieved in a single procedure.

Abstract
INTRODUCTION The management of Graves' ophthalmopathy is shared between endocrinologists and ophthalmologists. Assessment and treatment of the active inflammatory stage is based on the clinical activity and disease severity scores, often without detailed eye examination by the treating endocrinologist. MATERIALS AND METHODS We report a case of acute viral keratoconjunctivitis occurring during immunosuppressive treatment for Graves' ophthalmopathy which masked the signs, symptoms and response to treatment of the orbitopathy, posing a differential diagnostic challenge. RESULTS The apparent worsening of the ophthalmopathy and the increased clinical activity score led the treating endocrinologist to alter the management decisions. Ophthalmic examination confirmed the diagnosis of viral keratoconjunctivitis and immunosuppressive treatment was continued with significant final improvement of Graves' ophthalmopathy. DISCUSSION Ocular surface conditions, unrecognised by the treating physician, may complicate the assessment of thyroid ophthalmopathy when detailed eye examination is not performed. The diagnostic challenge of Graves' ophthalmopathy requires a combined approach by an endocrinologist and an ophthalmologist working as a team.

Abstract
PURPOSE To investigate the accuracy of the preoperative evaluation in identifying a membranous obstruction of the distal canaliculus and the success rate of an external dacryocystorhinostomy (DCR) when membranectomy of the canalicular obstruction is also performed. DESIGN Retrospective, interventional case series. METHODS The surgical records of the lacrimal cases operated at Moorfields Eye Hospital between January 1997 and December 1999 were reviewed. All the patients with evidence of a membranous block of the canalicular opening into the sac identified and excised during the course of a standard DCR procedure with silastic intubation and a minimum follow-up period of 12 months were selected for this study. The records were analyzed for preoperative evaluation with syringing and probing, surgical details, outcome, and complications. RESULTS In 59 (85%) cases a functional anastomosis was established after tube removal. Additionally, 5 cases (7%) had patent system but required later ectropion repair and considered successful. Only 4 (6%) patients needed further lacrimal surgery, and one was referred to the ENT department for nasal polyps. The silastic tube was removed at a mean period of 6 weeks (SD = 4; range, 2-24 weeks), and the mean follow-up period was 13 months (SD = 3; range, 12-29 months). The preoperative evaluation failed to identify the membranous obstruction in 30 (43%) cases, which were correctly diagnosed intraoperatively. CONCLUSIONS In our series the anatomic success rate of 92% after DCR with membranectomy is comparable to the outcome of the DCR procedure. The distal canalicular membranous obstruction is an anatomic factor that may lead to surgical failure if not identified and excised.

Abstract
INTRODUCTION The aim of this paper is to highlight the use of the Holmium YAG laser in the endoscopic placement of Lester Jones tubes in patients with a blocked canaliculus or failed lacrimal pump function. MATERIALS AND METHODS Sixteen cases with a non-functional canaliculus were included over a one-year period. Following caruncle excision, a 19 G needle is inserted through the medial canthal tissues into the nasal space. Nasal endoscopy confirms the accurate positioning in relation to the nasal anatomy. With the Holmium YAG laser, a tissue channel is fashioned around the guide needle through the structures of the lateral nasal wall to facilitate an accurate and secure placement of the Jones tube. RESULTS The endoscopic, laser-assisted placement reduces the operating time to less than 20 minutes, minimizes tissue trauma and does not require the initial surgical steps of an open DCR procedure. There were 14 cases (87.5%) with securely retained tubes and two cases (12.5%) that required tube replacement. The advantage of the procedure is especially great in revision surgery where the ostium is opened through scar tissue. CONCLUSIONS Nasal endoscopy with the assistance of the Holmium YAG laser offers simplicity and precision in the placement of Jones tubes. It minimizes tissue trauma and increases the surgical success rate.
