Abstract
Superior limbic keratoconjunctivitis (SLK) is an under-recognized condition characterized by a final common pathologic presentation of superior conjunctival and limbal inflammation and staining. Existing literature attributes both microtrauma and local inflammation, frequently in the setting of tear film insufficiency, as the underlying mechanisms that lead to a self-perpetuating pathologic process dependent in on inflammatory cells and signaling. Effective treatments act by targeting inflammation and by mitigating mechanical stressors. This critical review discusses the latest in our understanding of the pathophysiology of SLK and how it guides our treatment strategies.

Abstract
Graft-versus-host disease (GVHD) is characterized by tissue inflammation in the host following an allogeneic hematopoietic cell transplantation (HCT). The pathophysiology is complex and only incompletely understood yet. Donor lymphocyte interaction with the histocompatibility antigens of the host plays a crucial role in the pathogenesis of the disease. Inflammation may affect multiple organs and tissues, e.g., the gastrointestinal tract, liver, lung, fasciae, vaginal mucosa, and the eye. Subsequently, alloreactive donor-derived T and B lymphocytes may lead to severe inflammation of the ocular surface (i.e., cornea and conjunctiva) and the eyelids. Furthermore, fibrosis of the lacrimal gland may lead to severe dry eye. This review focuses on ocular GVHD (oGVHD) and provides an overview of current challenges and concepts in the diagnosis and management of oGVHD. Ophthalmic manifestations, diagnostic procedures, grading of severity and recommendations for ophthalmic examination intervals are provided. Management of ocular surface disease with lubricants, autologous serum eye drops, topical anti-inflammatory agents and systemic treatment options are described based on the current evidence. Ocular surface scarring and corneal perforation are severe complications of oGVHD. Therefore, ophthalmic screening and interdisciplinary treatment approaches are highly relevant to improve the quality of life of patients and to prevent potentially irreversible visual loss.

Abstract
Superior limbic keratoconjunctivitis (SLK) is characterized by chronic inflammation of the superior limbus and superior bulbar and tarsal conjunctivae. Patients also often have fine punctate staining of the limbus and adjacent area, superior limbic proliferation seen as thickening of the limbal epithelium and surrounding conjunctiva, and occasionally filaments at the superior limbus and upper cornea. SLK frequently presents with ocular irritation, foreign body sensation, and photophobia. SLK can be associated with other ocular and non-ocular conditions, such as thyroid disease. Although the pathogenesis of SLK is still unknown, it is thought to be related to mechanical injury, tear film instability, or an autoimmune/inflammatory etiology. Many patients with SLK can be asymptomatic or have symptoms that resolve or remit spontaneously. For symptomatic SLK, patients are managed medically with treatments such as lubricants, topical anti-inflammatory or immunomodulatory medications, punctal occlusion, and bandage contact lenses. Patients with symptoms refractory to medical management may need surgical interventions. We detail the current literature on the epidemiology, clinical manifestations, associated conditions, histopathology, pathogenesis, and treatment of SLK.

Abstract
In December 2010 and January 2012, 3% diquafosol sodium ophthalmic solution and 2% rebamipide ophthalmic suspension, respectively, appeared first in Japan as prescription drugs for the treatment of dry eye (DE). Since then, not only the diagnosis and treatment but also the understanding of the pathophysiology of DE have greatly advanced, and a new concept of layer-by-layer diagnosis and treatment for DE, respectively termed "tear-film-oriented diagnosis" (TFOD) and "tear-film-oriented therapy" (TFOT) was born. This new concept is currently in the process of expanding from Japan to other Asian countries. TFOD is the method used for the differential diagnosis of DE, which includes aqueous-deficiency DE (ADDE), decreased wettability DE (DWDE), and increased evaporation DE (IEDE), through the dynamics of tear film (TF) and breakup patterns (BUPs) after the eye is opened. BUPs and/or each diagnosed DE subtype are/is able to distinguish the insufficient components of the ocular surface that are responsible for each BUP in a layer-by-layer fashion. Aqueous fluid, membrane-associated mucins (especially MUC16), and the lipid layer and/or secretory mucins must be insufficient in ADDE, DWDE, and IEDE, respectively, and this allows for a layer-by-layer treatment to be proposed for each BUP via the supplementation of the insufficient components, using the topical therapy currently available. In Japan, TF breakup is regarded as a visible core mechanism for DE, and an abnormal breakup time (i.e., ≤5 seconds) and symptoms are currently used for the diagnosis of DE. Therefore, TFOD and TFOT could be an ideal and practical pathway for clinicians to manage DE.

Abstract
Lacrimal occlusion with punctal or canalicular plugs have been used to treat dry eye disease for more than 40 years. Indeed, punctal plugs constitute a safe and effective tool to retain the natural tear film and prolong the effect of tear substitutes. A wide variety of plugs is available, differing in their design, location (punctal versus canalicular) and their resorbability. There indications have increasingly broadened, and they are now one of the treatment options for numerous ocular surface diseases. Current research focuses on using punctal plugs for extended delivery of drugs to the ocular surface. This review addresses physiology of lacrimal drainage, available models of punctal plugs, their indications, practical details of prescribing and placing punctal and canalicular plugs, and possible complications.

Abstract
Punctal plugs are an effective treatment option for patients with aqueous-deficient dry eye refractory to topical medications. However, punctal plugs are not commonly used in clinical practice mainly because of various misconceptions, rather than clinical complications. We analyzed previous studies and present 5 misconceptions related to punctal plugs. The first and most important misconception is that ocular surface inflammation should be sufficiently controlled before punctal plug insertion. However, it is unclear how ocular surface inflammation can be sufficiently controlled in patients refractory to conventional topical medications. The second misconception is that silicone punctal plugs are made of nonabsorbable materials and, therefore, permanent. In fact, silicone plugs are reversible and can be easily removed if necessary. Therefore, depending on the specific type, nonabsorbable plugs may be classified as reversible or permanent. The third misconception is that punctal plugs disrupt normal tear drainage. However, punctal plugs maintain natural tears on the ocular surface for extended periods and reduce the frequency of artificial tear use. The fourth is that all punctal and canalicular plugs have similar effects. The efficacy and complication rates differ depending on plug types. The fifth misconception about punctal plugs is that they are effective only in aqueous-deficient dry eye disease. Many studies have reported that plugs are effective in a variety of ocular diseases and conditions. Understanding these 5 misconceptions may provide an opportunity to rethink the use of silicone punctal plugs in clinical practice.

A new strategy to sustained release of ocular drugs by one-step drug-loaded microcapsule manufacturing in hydrogel punctal plugs. Graefes Arch Clin Exp Ophthalmol 2017; 255:2173-2184. [PMID: 28887638 DOI: 10.1007/s00417-017-3755-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2016] [Revised: 06/20/2017] [Accepted: 07/17/2017] [Indexed: 10/18/2022] Open
Abstract
PURPOSE To design an injectable hyaluronate (HA)-based hydrogel system that contains drug-loaded microcapsules as resorbable plugs to deliver ocular drugs. METHODS In-situ drug-loaded, core-shell-structured chitosan (CS)@HA microcapsules were fabricated via HA hydrosol collecting in electrospun bead-rich CS fibers under continuous stirring. An injectable and cytocompatible hydrogel system with different degrees of chemical crosslinking maintained viscoelastic and sustained drug release for a long-term period of time at body temperature in vitro. RESULTS With the addition of adipic dihydrazide (ADH) or 1-Ethyl-3-(3-dimethyllaminopropyl) carbodiimide hydrochloride (EDCI), HA hydrosols transited from liquid to solid state at the gel point, with the G'/G″ ratio varying between 1.43 and 5.32 as a function of crosslinker concentration in the hydrogel phase. Ofloxacin (OFL) release from the mechanically mixed hydrosol system (CS-HA-A0-E0) and the micro-encapsulated hydrosol formulation (CS@HA-A0-E0) were respectively over 80% and 51% of the total drug load leaching out within 24 h. As for the drug-mixed hydrogel systems with low (CS-HA-A0.06-E0.15) and high (CS-HA-A0.06-E0.30) crosslinking density, the OFL release rate reached 38.5 and 46.6% respectively, while the micro-encapsulated hydrogel systems with low (CS@HA-A0.06-E0.15) and high (CS@HA-A0.6-E0.30) showed only (11.9 ± 2.7)% and (17.4 ± 3.5)% drug release respectively. CONCLUSIONS A one-step in-situ drug-capsulizing method is developed to fabricate a resorbable hydrogel punctal plug with extended drug release. The chemistry of the crosslinking reaction involves the formation of highly biocompatible HA derivatives. Thus, the hydrogel can be used directly in the tear drainage canalicular system.

Abstract
PURPOSE To report the therapeutic efficacy and safety of topical 0.1% lodoxamide in the long-term treatment of superior limbic keratoconjunctivitis. METHODS Sixty-seven eyes of 34 patients with active SLK were studied. Therapeutic response was analyzed according to modified-Ohashi parameters. All eyes were treated with 0.1% lodoxamide twice daily, and those with moderate or severe inflammation received a short course (7-14 days) of 0.1% fluorometholone acetate at presentation and during a relapse. Patients were evaluated at regular intervals and followed up for ≥3 months on continuous therapy. Primary endpoints included inflammatory response; rates of inflammatory control and remission; relapses while on therapy or on remission; and therapeutic failure rate. RESULTS The mean follow-up time on lodoxamide therapy was 15.3 months. The majority of eyes (82.0%) achieved control of inflammation in a mean time of 2.2 months. Of these, 42 (76.3%) eyes remained under control while on therapy for 13.8 months. There was a significant improvement of SLK-related signs by the third month on therapy (p < 0.05). A total of 24 (35.8%) eyes achieved remission. Relapses presented in 12 (18.0%) treated eyes and in 4 (16.6%) eyes on remission. Only 5 (7.4%) eyes failed to respond to therapy. In the majority of cases (95.3%), lodoxamide 0.1% was well tolerated and minor adverse effects not requiring stopping the medication were reported in only 4.7% of patients. CONCLUSIONS Lodoxamide 0.1% is an efficacious therapeutic alternative for the treatment of active and chronic SLK. This medication has proved to be safe and well tolerated.

Abstract
Numerous designs of punctal and canalicular plugs are available on the market. This variety presents challenges to ophthalmologists when choosing punctal plugs for the management of various ocular conditions. The aim of this literature review is to provide a classification system for lacrimal occlusive devices based on their location and duration of action as well as to identify different characteristics of each one of them. We want to give a comprehensive overview on punctal and canalicular plugs including their manufacturing companies, indications, and complications that have been reported in various articles. PubMed and Google Scholar were used to identify articles written in English as well as few articles written in Japanese, Chinese, Slovak, and Spanish that had abstracts in English. Nine different companies that manufacture punctal and canalicular plugs were identified and their plugs were included in this review. Punctal and canalicular plugs are used in the management of various ocular conditions including dry eye disease and punctal stenosis as well as in ocular drug delivery. Although they are a relatively safe option, associated complications have been reported in the literature such as infection, allergic reaction, extrusion, and migration.

Abstract
PURPOSE To evaluate efficacy of topical rebamipide for superior limbic keratoconjunctivitis (SLK) in patients with thyroid eye disease. DESIGN Retrospective, observational case series. METHODS Thirty-three eyes from 20 thyroid eye disease patients with SLK who received topical rebamipide (Mucosta ophthalmic suspension unit dose 2%; Otsuka Pharmaceutical Co, Ltd; chemical name, (2RS)-2-(4-chlorobenzoylamino)-3-(2-oxo-1, 2-dihydroquinolin-4-yl) propanoic acid) were included. The following items were evaluated before and 4 weeks after the start of treatments: presence or absence of SLK, rose bengal staining score, area and density classification of fluorescein staining, Schirmer test I results (without topical anesthesia), tear film break-up time, Hertel exophthalmometry values, and margin reflex distances 1 and 2. RESULTS Twenty-eight eyes showed complete disappearance of SLK after treatment (84.8%; P < .001). The other 5 eyes (15.2%) demonstrated significant improvement, but had residual punctate rose bengal staining and fluorescein staining near the superior corneal limbus. All 5 eyes exhibited at least 1 of the following findings: proptosis of more than 17.7 mm and upper or lower eyelid retractions or both. Incidence of upper eyelid retraction was significantly higher in eyes with SLK than in those without SLK at the 4-week follow-up (P = .021). The severity of rose bengal staining and fluorescein staining improved significantly after treatment (P < .001). Although the Schirmer test results remained constant before and after the treatment (P = .212), tear film break-up time increased significantly in the posttherapeutic state (P = .009). No serious adverse events were reported. CONCLUSIONS Topical rebamipide improved SLK in patients with thyroid eye disease, suggesting a first-line treatment in such patients.

Abstract
PURPOSE To evaluate the effect of punctal plug use in preventing dry eye after laser in situ keratomileusis (LASIK). MATERIALS AND METHODS A randomized clinical trial at a tertiary eye care center, Riyadh, Saudi Arabia. Participants underwent LASIK for myopia in both eyes and a lower punctal occlusion in one eye only while the other eye served as control. Both eyes received the same postoperative medications except for lubricant duration (subject eye: four times per day for one week; control eye: four times per day for 6 months). Participants were evaluated at 1 week, 2, and 6 months after surgery for signs and symptoms of dry eye. The main outcome measures were visual acuity; ocular surface parameters; and Ocular Surface Disease Index questionnaire. RESULTS Seventy-eight eyes of 39 patients were included in this study. The Ocular Surface Disease Index scores of eyes with punctal plugs were better at all follow-up visits, and the differences between both eyes were statistically significant (1 week, p < 0.0001; 2 months, p < 0.0001; 6 months, p = 0.008). At the final follow-up visit, the percentage of normal eyes was higher in eyes with punctal plugs for all ocular surface parameters (Schirmer 1 test, 94.9%; tear breakup time, 77.8%; punctate epithelial keratitis score, 71.8%) compared to eyes without occlusion (Schirmer 1 test, 92.3%; tear breakup time, 58.3%; punctate epithelial keratitis score, 53.8%); however, such differences were not statistically significant. CONCLUSION Punctal plug insertion after LASIK surgeries may minimize the need for frequent lubricant application and hence improve patient satisfaction.

Abstract
We investigated the efficacy of lacrimal punctal occlusion surgery with a cautery device in patients with chronic GVHD (cGVHD)-related dry eye, with recanalization of puncta and recurrent punctal plug extrusion. A total of 23 puncta from 14 eyes of 10 patients with chronic GVHD (cGVHD)-related dry eye underwent punctual thermal cauterization with a high-temperature disposable cautery device. All patients were refractory to conventional treatment, including artificial tear eye drops, autologous serum eye drops and vitamin A eye drops, and had a history of recanalization and recurrent punctal plug extrusion. The effect of lacrimal punctal cauterization by thermal cautery device was evaluated by changes in subjective symptom scores, corrected distance visual acuity, Schirmer's test values, fluorescein staining scores, rose bengal staining scores, and tear-film break-up time before and 3 months after the surgery. Subjective symptom scores, Schirmer's test values, fluorescein and rose bengal scores, and tear-film break-up time improved significantly 3 months after the surgery. Recanalization of puncta was not observed in all the cases (0 of 14 eyes, 0%). Lacrimal punctal cauterization was effective with no recanalization and significant improvements in subjective symptoms and the ocular surface environment in cGVHD-related dry eye patients who had been refractory to conventional treatments.

Abstract
PURPOSE To report the rate of recanalization and the efficacy of punctal occlusion surgery with a high heat-energy-releasing cautery device in patients with severe dry eye disease and recurrent punctal plug extrusion. DESIGN Prospective, interventional case series. METHODS Seventy puncta from 44 eyes of 28 dry eye patients underwent punctal occlusion with thermal cautery. All patients had a history of recurrent punctal plug extrusion. A high heat-energy-releasing thermal cautery device (Optemp II V; Alcon Japan) was used for punctal occlusion surgery. Symptom scores, best-corrected visual acuity, fluorescein staining score, rose bengal staining score, tear film break-up time, and Schirmer test values were compared before and 3 months after the surgery. Rate of punctal recanalization also was examined. RESULTS Three months after surgical cauterization, symptom score decreased from 3.9 ± 0.23 to 0.56 ± 0.84 (P < .0001). Logarithm of the minimal angle of resolution best-corrected visual acuity improved from 0.11 ± 0.30 to 0.013 ± 0.22 (P = .003). Fluorescein staining score, rose bengal staining score, tear film break-up time, and the Schirmer test value also improved significantly after the surgery. Only 1 of 70 puncta recanalized after thermal cauterization (1.4%). CONCLUSIONS Punctal occlusion with the high heat-energy-releasing cautery device not only was associated with a low recanalization rate, but also with improvements in ocular surface wetness and better visual acuity.

Abstract
PURPOSE To evaluate the effects of liquid nitrogen cryotherapy on superior limbic keratoconjunctivitis (SLK). DESIGN Interventional case series. METHODS In this clinical practice case series, the effects of liquid nitrogen cryotherapy on SLK were observed. Liquid nitrogen cryotherapy was performed using a Brymill E tip spray (0.013-inch aperture) with a double freeze-thaw technique. All subjects were outpatients who had local anesthesia with a single drop of topical proparacaine. The main outcome measure was the resolution of the disease process after treatment. RESULTS Four female patients (average age, 64 +/- 13 years) and seven eyes with SLK were treated with liquid nitrogen cryotherapy. Resolution of signs and symptoms occurred within two weeks. Disease recurred in two patients and three of seven eyes, although repeat cryotherapy eradicated SLK in all cases. The repeat cryotherapy was performed at three months postoperatively. There were no adverse ocular events. CONCLUSIONS Liquid nitrogen cryotherapy appears to be an effective alternative treatment for SLK as all subjects studied achieved long-term cures. Repeat cryotherapy may be necessary in some instances and may be performed three months after the first treatment.

Abstract
PURPOSE To evaluate the effectiveness of conjunctival resection combined with Tenon layer excision in treating superior limbic keratoconjunctivitis (SLK) and the involvement of mast cells in SLK. DESIGN Retrospective, interventional case series. METHODS Forty eyes of 30 SLK patients who were unresponsive to medical treatment received superior bulbar conjunctival resection, and another 20 patients who underwent cataract and retinal surgery served as a control group. The conjunctiva specimens from study and control patients were examined by hematoxylin and eosin staining and immunohistochemistry using antibodies against mast cell tryptase. RESULTS In all operated eyes, the clinical symptoms and signs, including irritation and redness and superior bulbar conjunctival hyperemia and superior tarsal conjunctival papillary hypertrophy, subsided significantly three months after the operation. Only three eyes had recurrence from the margin of conjunctival resection, and this was relieved after reoperation. Keratinized conjunctival epithelium, loss of goblet cells, and increased mast cell numbers (P<.05) were found in the SLK group. CONCLUSIONS Our cases demonstrate that superior bulbar conjunctival resection combined with Tenon layer excision is an effective treatment for SLK. The pathologic findings suggest that mast cells may play a role in the pathogenesis of SLK.

Abstract
PURPOSE To show poor adhesion between the conjunctiva and the sclera in eyes with superior conjunctivochalasis (CCh) and to introduce a new surgical approach by reinforcing adhesion between the conjunctiva and the sclera for correcting this deficiency. METHODS After conjunctival peritomy and removal of the loose Tenon remnants, "Tenon reinforcement" for conjunctival adhesion to the underlying sclera was achieved by transplantation of cryopreserved amniotic membrane with fibrin glue (group A, 9 eyes of 6 patients) or 10-0 nylon sutures (group B, 8 eyes of 6 patients) in 17 eyes of 12 patients with refractory superior CCh. RESULTS The mean age of patients was 68.2 +/- 9.8 years (range, 54-80 years). Superior CCh was associated with a superior limbic keratoconjunctivitis (SLK)-like clinical feature before surgery and found to exhibit dissolved Tenon capsule during surgery in all patients. During a mean follow-up of 3.7 +/- 1.9 months after surgery, all eyes achieved smooth conjunctival surface without any sign of CCh. Complete resolution of symptoms was seen in 9 eyes (52.9%) and significant resolution in 8 eyes (47.1%). There was no significant difference between groups A and B in improvement of symptoms and signs. No complications related to surgery were noted during follow-up. CONCLUSIONS We propose that loose and dissolved Tenon tissue is correlated with the development of superior CCh, which may result in an SLK-like appearance by blink-related microtrauma. Reinforcement of conjunctival adhesion onto the sclera by amniotic membrane with either fibrin glue or sutures is effective in alleviating symptoms and signs in eyes with superior CCh.

Abstract
PURPOSE To describe a method of quantifying the tear meniscus height (TMH) and using these values to diagnose patients with dry eye. METHODS Thirty-eight eyes of 19 healthy subjects and 14 patients diagnosed with dry eye were studied. Each eye received 2 microL of 1% fluorescein-sodium solution in the conjunctival sac, and digital photographs were taken of the external surface of the eye with a fundus camera. The tear meniscus was extracted from the digitalized image and used to measure the TMH with NIH image software. The correlation between the mean TMH and Schirmer test values or cotton-thread test values was evaluated. RESULTS The means of the upper and lower TMH in healthy subjects were 0.22 +/- 0.06 and 0.24 +/- 0.08 mm, respectively. The comparable values in patients with dry eye were 0.17 +/- 0.04 and 0.17 +/- 0.07 mm (upper TMS, P = 0.01; lower TMH, P = 0.04; unpaired t test). A significant correlation was found between the TMH and Schirmer test values (r = 0.72, P = 0.01) but not with cotton-thread test values. CONCLUSIONS Fluorescein photographs of the eye can be used to quantify the upper and lower TMH separately and simultaneously without specialized equipment. This technique can be used for the diagnosis of dry eye.

Abstract
PURPOSE To evaluate the efficacy of supratarsal triamcinolone injection in the treatment of superior limbic keratoconjunctivitis (SLK). METHODS Forty eyes of 20 patients were diagnosed with SLK. All eyes with long-standing severe ocular irritation unresponsive to topical steroid and artificial tears were treated with supratarsal triamcinolone injection in addition to ongoing treatment of dry eye. Objective tarsal conjunctiva inflammation, bulbar conjunctiva, cornea staining, and subjective symptom gradings were performed before and after 2 weeks of therapy. All patients underwent laboratory evaluations of underlying systemic abnormalities. RESULTS All 40 eyes responded well to treatment and had long-term (average, 7.8 months) improvement of irritation and dry sensation and improvement of inflammation and staining of conjunctiva and cornea. Fourteen patients (70%) had associated autoimmune diseases. There were no irreversible complications related to this therapy. CONCLUSIONS Supratarsal triamcinolone injection effectively and rapidly resolved symptoms and signs associated with SLK. It is helpful as primary or adjunctive therapy for SLK.

Abstract
PURPOSE To describe a unique presentation of superior limbic keratoconjunctivitis (SLK) that occurred after upper eyelid blepharoplasty and to review the literature regarding the current theories of SLK pathogenesis and its treatment. METHODS A 48-year-old woman presented with a 2-year history of irritation and foreign body sensation in both eyes that began immediately after bilateral upper eyelid blepharoplasty. Her symptoms were unresponsive to therapy with lubricating eyedrops and ointments, cyclosporine 0.05% drops, and silver nitrate cauterization. The patient subsequently underwent surgical resection of the superior bulbar conjunctiva in both eyes. RESULTS Complete resolution of SLK symptoms. CONCLUSIONS The pathogenesis of SLK has been associated with mechanical injury to the superior limbus and superior bulbar conjunctiva. The development of SLK after upper eyelid blepharoplasty in our patient supports this theory and should be considered a possible adverse consequence of blepharoplasty.

Abstract
PURPOSE To historically review the technique of impression cytology as a minimally invasive diagnostic tool for ocular surface pathology. METHODS A comprehensive review of published literature cited in PubMed since the first description of impression cytology in 1977 up to date has been undertaken. RESULTS A wide range of processing methods have been adapted to the technique of impression cytology (from conjunctiva, cornea or limbus): regular light microscopy with different stainings, transmission and scanning electron microscopy, immunofluorescence, immunocytochemistry, polymerase chain reaction analysis, immunoblotting analyses, or flow cytometry. At present, it is widely used as a non-invasive alternative to the full-thickness biopsy for the obtention of epithelial cells from the ocular surface. CONCLUSIONS Impression cytology represents a non- or minimally invasive biopsy of the ocular surface epithelium with no side effects or contraindications. It has demonstrated to be a useful diagnostic aid for a wide variety of processes involving the ocular surface. In addition, and mainly during the last decade, its use as a research tool has experienced an enormous growth and has greatly contributed to the understanding of ocular surface pathology.

Abstract
PURPOSE To report the early success of the use of topical cyclosporine A 0.5% drops to treat Theodore's superior limbic keratoconjunctivitis (SLK). DESIGN A retrospective noncomparative case series. PARTICIPANTS Five patients diagnosed with SLK. INTERVENTION All five patients were treated with topical cyclosporine A 0.5% drops as primary or adjunctive therapy after treatment failure in some of prednisolone acetate 1% drops and topical silver nitrate 0.5% application. Topical cyclosporine A 0.5% drops were used four times a day in both eyes. MAIN OUTCOME MEASURES Resolution of symptoms (foreign body sensation and irritation) and signs (rose bengal staining, tarsal papillary reaction, and injection). RESULTS All five patients had long-term (6 months to 3 years) improvement of irritation and foreign body sensation, as well as improvement of injection and filamentary keratitis. Aside from burning on instillation, there were no complications related to this therapy. CONCLUSIONS Topical cyclosporine A 0.5% is helpful as primary or adjunctive therapy for SLK. It may also be used as a maintenance drug to prevent recurrence. Further study may delineate the specific role and treatment parameters for the use of topical cyclosporine A 0.5% in the treatment of SLK.

Abstract
PURPOSE To introduce a new surgical procedure for treating superior limbic keratoconjunctivitis (SLK) and to suggest the association of SLK with conjunctivochalasis. DESIGN Interventional case series. METHODS Six eyes of five patients with long-standing severe ocular irritation unresponsive to treatment with topical steroid and artificial tears were operated on using our new procedure. This technique consists of four steps as follows: (1) Rose bengal (RB) staining is used to localize the abnormal conjunctival area; (2) an arc-like conjunctival incision is placed from the 2 to the 10 o'clock position adjacent and distal to the RB-stained area; (3) the conjunctiva is resected to form a crescent using the arc-like incision as the base; the size of the resection is determined by conjunctival redundancy after removal of the subconjunctival connective tissue; and (4) the crescent conjunctival opening is closed with interrupted sutures. In two eyes, the new surgical procedure was performed together with surgery for inferior bulbar conjunctivochalasis. RESULTS In all operated eyes, RB staining had disappeared by the end of the second postoperative week; recovery from symptoms and loss of inflammation were recorded by 1 month after treatment. In the case with the longest follow-up (14 months), there was cytologic evidence of goblet cell recovery at 3 months after the operation. In another, there was normalization of the nucleo/cytoplasmic ratio of conjunctival cells without the appearance of goblet cells. CONCLUSIONS Our treatment very effectively resolved symptoms associated with SLK, even in eyes unresponsive to conventional therapy with eye drops. Considering that we did not address the diseased part of the conjunctiva but rather the adjacent conjunctival redundancy, we propose that superior bulbar conjunctivochalasis is involved in the pathogenesis of SLK.

Abstract
PURPOSE To determine whether canalicular occlusion with collagen and silicone plugs reduces the severity of symptoms in patients with conjunctivitis secondary to dry eye. METHODS This was a prospective, randomized, double-masked study conducted at a single center in Mexico, in which 61 patients with dry eye/conjunctivitis were assigned to progressive lacrimal occlusion with collagen and silicone plugs or a sham procedural group. Outcome variables included total and individual dry eye and conjunctivitis symptom scores, moisturizing agent usage, best-corrected visual acuity, ocular comfort level, visual performance, corneal/conjunctival fluorescein staining, and incidence of adverse events. RESULTS Total dry eye and conjunctival symptom scores were reduced by 43.7 and 33.7%, respectively 2 weeks after occlusion of all four lacrimal canaliculi with collagen plugs, increasing to 77.4 and 72.1% 2 weeks later following superior canalicular occlusion of both eyes with silicone plugs and inferior placement of collagen plugs. At the 8-week visit (4 weeks after silicone plug implantation of the inferior canaliculi of both eyes), the reduction in total dry eye and conjunctival symptom scores further increased to 94.2 and 93.0%, respectively, accompanied by a marked decline in each of the seven individual symptom scores (dryness, watery eyes, itching, burning, foreign body, fluctuating vision, and light sensitivity). In concert with these changes, moisturizing agent usage and corneal/conjunctival fluorescein staining decreased in a progressive fashion over the 8-week study period, and best-corrected visual acuity, ocular comfort, and visual performance improved in the absence of any treatment-related adverse events except for one case of epiphora. The response of patients to lacrimal occlusion can be sharply contrasted with the sham procedure group, which remained relatively unchanged from baseline at each of the study visits. CONCLUSIONS Progressive lacrimal occlusion with collagen and silicone plugs was of clinical benefit to patients with dry eye and conjunctivitis.

Abstract
AIMS To assess the outcome of a surgical punctal occlusion technique. METHOD Prospectively, 11 consecutive patients (26 puncta) with severe dry eyes recalcitrant to maximal medical therapy underwent permanent punctal occlusion at a tertiary eye care centre between January 1999 and December 2000. The epithelium of the punctum and the vertical portion of the canaliculus was removed with a corneal rust ring burr. The bared punctum-canaliculus complex was closed with a 6-0 chromic suture. Success was measured by the complete functional occlusion of the punctum, tear function tests, and patients' response. RESULT Five males and nine females, aged 26-77 enrolled in the study with three patients later excluded. As of November 2001, the remaining 11 patients had follow up ranging from 14 to 34 months (mean 24 months; median 24 months). 24 puncta (or 92%) remained occluded, including four puncta which showed anatomical reopening. Seven out of 11 patients (63.6%) stated they had symptomatic improvement regardless of their objective findings. CONCLUSION This technique resulted in a 92% permanent occlusion of the puncta and compared favourably with other reported techniques. Punctal occlusion does not appear to correlate well with Schirmer tests, the frequency of lubrication, and/or subjective feelings in these patients.

Abstract
PURPOSE To evaluate the clinical efficacy and safety of silicone punctal plugs in various ocular surface disorders. PATIENTS AND METHODS Medical records of patients who underwent silicone punctal plug insertion from January 1996 to November 2000 were retrospectively reviewed. The clinical data collected included sex and age of the patients, indications for plug insertion, symptoms, corneal fluorescein staining and frequency of lubricant use at baseline and at 4 +/- 2 weeks after the insertion, location (upper versus lower punctum), initial versus replacement plug, spontaneous extrusion or removal of the plug, and percentage of complications and punctum cauterization. RESULTS There were 203 eyes of 153 patients (126 women and 27 men) in the study group. The total number of silicone punctal plug procedures was 312. Dry eye syndrome was the most common indication for punctal plug treatment (127 eyes, 62.5%), followed by epitheliopathy after penetrating keratoplasty (32 eyes, 15.8%). The symptoms improved in 150 (73.9%) of 203 eyes at 4 +/- 2 weeks' follow-up. The mean score of the fluorescein staining of the cornea was reduced from 2.7 +/- 0.1 to 1.3 +/- 0.1 with silicone punctal plug treatment at 4 +/- 2 weeks' follow-up. This reduction was statistically significant (p< 0.01). The overall success rate at 4 +/- 2 weeks follow up was 76.8%. The frequency of the lubricant use was significantly decreased with punctal plug treatment (p< 0.001). Considering all plugs, the estimated probability of plug retention was 49.4% with 85.1 +/- 7.3 weeks as the mean survival time. There was no statistical difference in plug retention rates between lower (49.6%) and upper (48.7%) plugs (p= 0.15). Retention rate of first plugs (53.5%) was significantly higher than that of second plugs (32.0%) (p= 0.05). The spontaneous total extrusion of silicone punctal plug was the most common complication in our study (158 plugs, 50.7%). The plug was removed in 14 eyes (14 plugs, 6.9%) because of epiphora in 11 eyes and conjunctival erosion in three eyes. The percentage of punctum cauterization performed in our population was 10.8%. CONCLUSIONS Punctal plug insertion is a simple, effective, safe, and reversible method to treat aqueous tear deficiency and other ocular surface diseases, such as epitheliopathy after penetrating keratoplasty, superior limbic keratoconjunctivitis, neurotrophic keratitis, recurrent corneal erosions, and toxic epitheliopathy not controlled by lubrication with preservative-free tears. However, spontaneous extrusion of silicone plug occurs commonly. Careful choosing of the optimal plug size and close follow-up are recommended to ensure the success of the treatment.

Abstract
PURPOSE To determine the efficacy of autologous serum drops in the treatment of superior limbic keratoconjunctivitis (SLK). METHODS Twenty-two eyes of 11 patients were diagnosed with SLK. All eyes were treated with 20% diluted autologous serum eyedrops 10 times a day in addition to ongoing treatment of dry eye. Fluorescein and rose bengal staining scores, as well as subjective symptom gradings, were performed before and after 4 weeks of therapy. RESULTS Nine of the 11 patients responded well to treatment (82%). The average rose bengal and fluorescein score improved ( p < 0.05), and there was subjective improvement. CONCLUSION Autologous serum application can be used as an alternative mode of therapy in SLK.

Abstract
PURPOSE MUC5AC has been identified as a major secretory mucin of conjunctival goblet cells and precorneal tear film. However, no method has been reported to quantify MUC5AC protein in human tears. The objective of this study was to establish a method to measure the amount of MUC5AC in human tears and to correlate the amount of MUC5AC with age, gender, and dry eye diseases. METHODS A goat antibody was raised to synthetic peptides corresponding to nonglycosylated epitopes of human MUC5AC mucin. This antibody and a horseradish peroxidase-coupled second antibody were used to develop a quantitative immunoassay to measure the MUC5AC concentration of tear samples collected on Schirmer strips. Porcine stomach mucin was used as a standard for the assay. The chemiluminescent MUC5AC signal was digitized and quantified. Tear samples from 19 healthy volunteers and 31 clinically diagnosed dry eye patients were analyzed. RESULTS MUC5AC concentration in human tears ranged from undetectable to more than 200 microg/mL porcine stomach mucin equivalent. In the healthy population, low, moderate, and high concentrations were found in the tear samples from younger and older persons and from both men and women. The mean MUC5AC content in tears was lower in the dry eye patients than in the age- and gender-matched healthy individuals. CONCLUSIONS A method was established to quantify MUC5AC in human tear samples obtained on Schirmer strips. There was no correlation between the amount of MUC5AC and age or gender in the healthy population. Dry eye disease patients, however, typically showed reduced concentrations of soluble MUC5AC in the tear film.

Abstract
PURPOSE Silicone punctal plugs are widely used to conserve moisture in tear-deficient eyes. We studied the efficacy and tolerability of punctal plugs in symptom reduction and improvement of ocular surface disease parameters in dry eye syndrome. METHODS We reviewed the records of 50 consecutive patients with dry eye syndrome who were symptomatic despite maximally tolerable lubricant therapy and had bilateral lower punctal plug insertion. After plug insertion, all patients (41 women and nine men) had 6 months or more of follow-up. The subjects ranged in age from 22 to 57 years (mean, 30 years). We recorded subjective and objective improvement of ocular surface disease, frequency of lubricant use, need for upper punctal occlusion, and occurrence of complications after plug insertion. We determined plug retention rates using Kaplan-Meier analyses and assessed associated factors using Cox proportional hazards models. RESULTS Six months after initial plug placement, 43 of 50 patients (86%) were symptom free, 28 of them (56%) with plugs alone, and 38 patients (76%) had stopped using lubricants on a daily basis. Spontaneous loss of plugs was common, especially in the initial 3 months of follow-up. Considering all plugs, the estimated probability of plug retention was 63% after 6 months of follow-up. Puncta refitted after initial plug loss were twice as likely to lose the replacement plug (P =.02). Upper punctal plugs showed a 4.3-fold higher risk of loss compared with plugs inserted in lower puncta (P <.0001). CONCLUSIONS There is both a reduced dependency on artificial lubricants and relief of symptoms of dry eye after punctal plugs. However, spontaneous plug loss occurs in a substantial minority of patients. Patient education and close follow-up, particularly in the first 3 months, is recommended to detect plug loss and ensure adequate control of the disease.

Abstract
Origins of superior limbic keratoconjunctivitis (SLK) are not well understood. Prompted by suggestions that pressure and friction may contribute to SLK, this paper, using evidence from the literature and from personal Kodachrome records, aims to assess, and if appropriate, enhance this understanding. The survey disclosed evidence confirming mechanical aetiology. Support is presented for the notion that SLK arises from soft tissue microtrauma: (i) between tarsal and bulbar surfaces; and (ii) between conjunctival stroma and sclera. In each pair the two apposed tissues are in repetitive motion relative to each other. It is concluded that SLK arises because nonstandard combinations of multiple predisposing and/or trigger factors exceed the physiological tolerance of mechanical stresses upon the ocular surface and tissues. Through their effects on particular tissues, eight separate stressing forces were perceived. The many contributing factors in four categories are integrated into a new aetiologic concept.

Abstract
Tears undergo four processes: production by the lacrimal gland, distribution by blinking, evaporation from the ocular surface and drainage through the nasolacrimal duct. Abnormalities in any of these steps can cause dry eye. There are two kinds of tear production, basic and reflex, which can be distinguished from each other by the Schirmer test with nasal stimulation. Reflex tearing is important because it supplies such essential components as EGF and vitamin A, whose deficiency may cause squamous metaplasia. There is no reflex tearing in Sjogren's syndrome because of destruction of the lacrimal gland. In cases of diminished or absent reflex tearing, topical autologous serum is the treatment of choice. Even when there is adequate tear production, insufficient distribution, such as occurs with the decreased blinking associated with the use of video display terminals (VDT), may cause dry eye. Any process or activity that suppresses blinking interferes with tear distribution. Tear evaporation increases under certain conditions and in some diseases. When the exposed ocular surface area is increased, such as in VDT work, tear evaporation increases. Meibomian gland dysfunction (MGD) also causes increased tear evaporation by altering the quality of the oily layer in tears. Tear evaporation can be suppressed by using a warm compresser or a humidifier, narrowing the palpebral fissure, or wearing protective eyeglasses. The tear clearance rate is measured by fluorescein dye dilution in the conjunctiva. When the tear clearance is low, inflammatory cytokines or preservatives accumulate in the conjunctival sac, resulting in ocular surface diseases. Frequent use of artificial tears without preservative is the key treatment. A differential diagnosis of the abnormalities of tear dynamics can give us a proper understanding of the pathogenesis of dry eye. With this knowledge, we can formulate an efficient therapeutic approach.

Abstract
PURPOSE To outline important concepts for treating ocular surface and tear disorders. METHOD A review was conducted of recently published findings. RESULTS Five concepts were delineated: ocular surface health is ensured by a close relationship between ocular surface epithelia and the preocular tear film; a stable tear film is inherently maintained by external adnexae; the intact protective mechanism is controlled by effective neuroanatomic integration; corneal epithelial stem cells are located at the corneoscleral limbus; and ocular surface epithelial cell function is supported by stromal fibroblasts and matrix. CONCLUSIONS These concepts stress that ocular surface epithelia and the preocular tear film function as a unit and, furthermore, that several corneal and external diseases can be categorized as ocular surface and tear disorders. These concepts also help one formulate unified diagnostic and therapeutic strategies for management of these diseases.
