Clinical Effectiveness, Safety, and Compliance of Two Compounded Formulations of Tacrolimus Eye Drops: An Open-Label, Sequential Prospective Study. Int J Mol Sci 2024; 25:9847.

Abstract
Ophthalmic tacrolimus compounded formulations are usually made from the commercial intravenous presentation, which contains ethanol as a solubilizer due to the low solubility of tacrolimus. The use of cyclodextrins is presented as an alternative to ethanol, an ocular irritant excipient, to avoid its long-term irritant effects. Open-label, sequential, prospective study to compare effectiveness, safety, and adherence of a new formulation of 0.015% tacrolimus with cyclodextrins (TCD) versus 0.03% tacrolimus with ethanol (TE). The ocular evaluation was assessed by ocular signs, corneal staining, subjective questionnaires as Visual Function Questionnaire (VFQ-25) and Visual Analogue Scale (VAS) of symptoms, lacrimal stability, ocular redness, and intraocular pressure. Compliance was assessed by VAS of adherence and empirically (difference between theoretical and actual consumption). Clinical ocular signs and corneal staining score remained stable for most patients 3 months after switching formulations. The TCD formulation did not modify the tear stability and intraocular pressure of the treated patients compared to the TE formulation. TCD eye drops significantly decreased the subjective pain values on VFQ-25 scale and burning sensation on the VAS symptom scale in comparison to TE formulation after 3 months after the change to TCD formulation. The novel tacrolimus in cyclodextrins formulation is a promising alternative for treating inflammatory ocular pathologies refractory to first-line treatments.

Abstract
Vernal keratoconjunctivitis (VKC) is a chronic severe ocular allergic inflammation mostly observed in children and young adults. The ocular manifestations are the expression of multifactorial immune mechanisms that generally have a good prognosis, however long-term inflammation may remarkably reduce the visual function due to complications and poor therapeutic responses. Lack of responsiveness to a drug or treatment is relatively common in VKC and it is not only due to corneal involvement, which is considered the main sign of severity. The concept of refractory may be relative to multiple factors including the clinical condition, systemic co-morbidities, previous or concomitant drugs or regiments, compliance, patient's psychological condition or expectations, type of exposome and environmental conditions, doctor's experience and expectations, or timing of clinical evaluation. In this narrative review, the authors propose a definition of refractory VKC based on revised literature and clinical experience and consider potential new treatments for refractory patients and surgical management in case of complications.

Abstract
The purpose of this study is to emphasize topical tacrolimus's role in treating anterior segment diseases in ophthalmology. The present study analyzed research papers and publications from international databases, including Pubmed, MedLine, Google Scholar, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), and Scopus to highlight the significance and advantages of topical application of tacrolimus and its efficacy in treating allergic eye disorders, immune-mediated diseases, and other ocular surface disorders. Tacrolimus and cyclosporine are the two most commonly used topical immunosuppressants in ophthalmology. Tacrolimus is a selective calcineurin inhibitor administered for the prevention and treatment of allograft rejection in solid organ transplant recipients and has a similar mechanism of action to cyclosporine. Management of immune-mediated inflammatory anterior segment requires intense immunosuppression and studies have shown that tacrolimus is ten to hundred times more effective than cyclosporine.

Abstract
PURPOSE This meta-analysis aimed to review the safety and efficacy of topical cyclosporine A (CsA) and topical tacrolimus in allergic eye disease. METHODS A systematic search identified thirteen studies and a total of 445 patients for inclusion, making this the largest meta-analysis published on the subject. The current review was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). RESULTS Thirteen randomized control trials were included in the meta-analysis. Eleven studies used CsA as the treatment, and two used Tacrolimus. In total, 445 participants were included, of whom 76.6% were male. The mean age of participants across the included studies was 14 years. All studies reported clinical signs as evaluated by an examining clinician. Signs were usually assessed by anatomical region, with the most common regions being the conjunctiva and the cornea, and the most common signs assessed were hyperemia and papillae. Three studies accounted for more than 50% of the meta-analysis's weight. Effect size (d) ranged from - 2.37 to - 0.03, negative values favoring immunomodulators. Fixed Effect Meta-Analysis returned an SMD of - 0.81 (95% CI [- 0.98, - 0.65]). However, there was significant heterogeneity (I2 = 61%, Qw = 30.76) in the outcome measure (P = 0.0021); therefore, a random-effect meta-analysis was also completed in which the pooled SMD was - 0.98 (95% CI [- 1.26, - 0.69], τ2 = 0.16). CONCLUSIONS This study affirms the current scientific community's stance that immunomodulators effectively treat clinical signs, including blepharitis, conjunctival hyperemia, edema, papillae, and corneal damage in severe ocular allergic disease.

Abstract
Background Vernal keratoconjunctivitis (VKC) is an allergic conjunctival inflammation with severe ocular complications if left untreated. The current management regimen is plagued with adverse effects, long-term problems, and clinical relapses. Tacrolimus offers an alternative treatment option, and long-term studies are needed to determine its efficacy. Methods A two-year follow-up based study was conducted on moderate to severe VKC patients, who were prescribed tacrolimus skin ointment. The 5-5-5 exacerbation scale was used for the monitoring and grading severity of the disease. Analysis of variance (ANOVA) and intergroup comparisons were conducted on exacerbation scale scores among follow-ups. Results A significant reduction was observed in the total score of severity from baseline (203.17±102.05) to three months' follow-up (69.94±70.54), and it kept reducing for 18 months post therapy. Similar results with statistically significant reduction were observed for all grades of the scale. The relapse rate was 5.71% within a month after therapy cessation, and none of the other patients showed relapse afterward. No significant ocular and systemic complications were observed during the study. Conclusion Tacrolimus is effective in the long-term management of VKC without the complications of conventional steroid-based therapy.

Abstract
Vernal keratoconjunctivitis (VKC) is a chronic, progressive, and potentially sight-threatening form of ocular inflammatory disease that primarily affects children and young adults. Prevalence varies by region, ranging from <2 per 10,000 in the United States to as high as 1,100 per 10,000 in parts of Africa. The rarity of VKC in developed countries can make differential diagnosis challenging, and treatment is often delayed until the disease is advanced, and symptoms are significantly impacting patients' quality of life. Although once viewed primarily as an immunoglobulin E-mediated condition, approximately 50% of patients with VKC do not exhibit allergic sensitization. It is now recognized that the immunopathology of VKC involves multiple inflammatory pathways that lead to the signs, symptoms, and conjunctival eosinophilic and fibroproliferative lesions that are a hallmark of the disease. We examine the evolution of our understanding of the immunopathology of VKC, the expanding VKC treatment armamentarium, the clinical implications of emerging treatment approaches, and future directions for VKC research and practice.

Abstract
A 46-year-old male, with no chronic medical illness, complained of pain, tearing, and redness for one-month duration, with no photophobia, discharge, or decrease in visual acuity. Examination revealed a small, painful, red swelling in the left sclera. Slit-lamp examination using a narrow bright slit beam revealed edema of the episcleral layer and injection of the superficial episcleral blood vessels. The rest of the anterior segment exam and fundoscopy were normal. The laboratory investigations and systemic workup were normal. The patient was initially treated with prednisolone acetate (Pred Forte) 1% every three hours per day for one week, and then four times per day for another week, and tapered gradually over eight weeks with systemic nonsteroidal anti-inflammatory drugs (NSAIDs) as diclofenac sodium for eight weeks with mild improvement of clinical symptoms, but the size of the lesion remained without any change and the patient started to have a relapse of symptoms at the end of the course. Topical tacrolimus drops of 0.1% concentration were prepared in the pharmacy under complete sterile precautions and were used four times per day for the following six weeks duration instead of the initial therapy (steroids and NSAIDs). Tacrolimus drops were then tapered gradually over another six weeks duration. The patient showed dramatic suppression of inflammation and exceptional remission of symptoms with complete resolution of the episcleritis. Topical tacrolimus is very effective in the treatment of nodular episcleritis, which is resistant to steroid therapy. Patients with nodular episcleritis suffer from prolonged bouts of inflammation that are characteristically more painful than the diffuse type and may be associated with other systemic diseases. The case is steroid-resistant nodular episcleritis, which did not respond to the usual treatment and showed a good response to treatment with tacrolimus, which was first introduced in episcleritis. Tacrolimus is being used in other ocular diseases, but its use in episcleritis is unique.

Abstract
Background Topical immunosuppressants such as tacrolimus in different concentrations are a breakthrough in the management of recalcitrant vernal keratoconjunctivitis (VKC); however, there is a lacks of comparative studies to guide their use in VKC management. Objective To compare the efficacy and safety of tacrolimus 0.03% and 0.1% eye ointment in the treatment of recalcitrant VKC. Design A retrospective comparative single-centre observational study. Method We reviewed records of a total of 48 recalcitrant VKC patients treated with two different strengths of tacrolimus ointment between April 2016 and March 2017. Of these, 39 fulfilled the inclusion criteria and were categorized into two groups, A and B, depending on the use of strength of tacrolimus (0.03% and 0.1%) used, respectively. Group A had 18 patients, while group B had 21 patients. Thirty-six patients, 18 from each group, were finally analysed and compared. Records of patients were explored for the subjective symptoms and objective sign score of the patient at baseline and at each time point. The main outcome measures were composite scoring and comparison of total subjective symptom scores (TSSSs) and total objective sign scores (TOSSs) within and between the groups at each follow-up. Percentage of patient with significant reduction in symptom and sign scores as compared with baseline was considered success of treatment. Chi-square and t-tests were used for comparison of outcomes between both groups. Results Mixed variety was most commonly encountered type of VKC. The signs and symptoms were significantly reduced in patients with treatment in both groups (p = 0.001) in all types of VKC. However, in group B, there was significant improvement in the size of papillae (p = 0.04) as compared baseline in contrast to group A. Side effects like burning and stinging in group B were significantly higher as compared with group A. Conclusions Both strengths of tacrolimus (0.03% and 0.1%) are effective in all forms of recalcitrant VKC. Papillary component of VKC responds better with higher strength (0.1%) but is associated with more significant side effects. Different strengths of tacrolimus can be used strategically depending upon the severity and clinical type of VKC to intensify outcome and minimize side effects.

Abstract
Background Vernal keratoconjunctivitis (VKC) is a bilateral, recurrent, chronic conjunctival inflammatory disease with seasonal exacerbations. This study aimed to assess the efficacy and safety of tacrolimus 0.03% eye ointment in the management of chronic VKC. Methods This was an open-label, prospective, non-randomized, comparative interventional study that enrolled 50 patients with chronic VKC, who were allocated to one of two groups. The first group was treated with tacrolimus 0.03% eye ointment twice daily for 2 months then once daily for 2 months, followed by once every other day for another 2 months. The control group was treated with standard anti-allergic drugs, topical fluorometholone 0.1% eye drops three times daily for 2 weeks and gradually tapered for another 2 weeks, with topical olopatadine 0.1% administered twice daily during the follow-up period. Disease severity was assessed using a four-point scale for symptoms and signs. Treatment efficacy was assessed by analyzing changes in symptoms and signs, and by clinical photography. Results Fifty patients with bilateral chronic VKC completed the follow-up. The mean (standard deviation) ages of the tacrolimus and control groups were comparable (16.20 [5.10] years versus 16.48 [4.19] years, P > 0.05). The most commonly reported symptom was itching, and the most common signs were papillary hypertrophy and conjunctival hyperemia. All symptoms and signs were significantly reduced after treatment in both groups. The tacrolimus group showed a more significant improvement at 3 and 6 months in the mean composite symptom score (both P < 0.05) and in the mean composite sign score (both P < 0.05). Regarding complications, one case of increased intraocular pressure occurred in the control group (4%) after 2 weeks of steroid treatment, while there were no complications in the tacrolimus group, except for some reports of stinging sensation, which was well tolerated. Conclusions Treatment of chronic bilateral VKC with tacrolimus 0.03% eye ointment is effective and safe. It could be considered an alternative treatment to reduce steroid-associated complications in patients with chronic VKC. Future double-blinded clinical trials with a longer follow-up period are necessary to confirm our findings and to determine the long-term safety of topical tacrolimus 0.03% ointment in VKC.

Abstract
Purpose: To assess the effect of different concentrations of tacrolimus eye suspension on the epithelium and stromal keratocytes of human corneas and investigate whether it can be safely used for severe cases of vernal keratoconjunctivitis (VKC). Methods: Tacrolimus eye suspension was prepared in a range of concentrations of 0.005%, 0.01%, 0.05%, 0.1%, and 0.2%. Molecular analysis was performed ex vivo on human corneas (n = 18), obtained from the eye bank. Transparency and thickness of each cornea were measured while live/dead staining was performed using a triple labeling assay. An incremental concentration approach was then tested on three severe cases of VKC. Results: All tested tacrolimus concentrations showed no significant changes in corneal thickness or transparency. In corneas treated with 0.1%, rare scattered dead cells were observed, while the folds of corneal surfaces were mostly viable, unlike concentrations higher than 0.1% and lower than 0.05%. Stromal cell densities were highest in the 0.1% tacrolimus treatment condition. Incremental concentrations of tacrolimus suspension were shown to significantly improve VKC cases, where the concentration used for each case depended on the severity of the case. Conclusions: Topical administration of tacrolimus was not toxic to human corneal cells at all tested concentrations, and the 0.1% concentration has shown the best viability of the corneal tissue. Tacrolimus eye suspension was shown to be safe and effective for use in severe VKC and is proposed as a topical ocular immunosuppressant drug enabling clinicians to incrementally increase the drug concentration according to the clinical severity of the disease to achieve the optimal therapeutic response.

Physicochemical Stability of a Novel Tacrolimus Ophthalmic Formulation for the Treatment of Ophthalmic Inflammatory Diseases. Pharmaceutics 2022; 14:pharmaceutics14010118. [PMID: 35057013 PMCID: PMC8778879 DOI: 10.3390/pharmaceutics14010118] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2021] [Revised: 12/29/2021] [Accepted: 12/29/2021] [Indexed: 11/17/2022] Open
Abstract
Tacrolimus is an immunosuppressant used to treat a large variety of inflammatory or immunity-mediated ophthalmic diseases. However, there are currently no commercial industrial forms available that can provide relief to patients. Various ophthalmic formulations have been reported in the literature, but their stability has only been tested over short periods. The objective of this study was to evaluate the physicochemical stability of a preservative-free tacrolimus formulation (0.2 and 1 mg/mL) at three storage temperatures (5 °C, 25 °C and 35 °C) for up to nine months in a multidose eyedropper. Analyses performed were the following: visual inspection and chromaticity, turbidity, viscosity, size of micelles, osmolality and pH measurements, tacrolimus quantification by a stability-indicating liquid chromatography method, breakdown product research, and sterility assay. In an in-use study, tacrolimus quantification was also performed on the drops emitted from the eyedroppers. All tested parameters remained stable during the nine month period when the eyedrops were stored at 5 °C. However, during storage at 25 °C and 35 °C, several signs of chemical instability were detected. Furthermore, a leachable compound originating from a silicone part of the eyedropper was detected during the in-use assay. Overall, the 0.2 mg/mL and 1 mg/mL tacrolimus ophthalmic solutions were physicochemically stable for up to nine months when stored at 5 °C.

A comparative study between ciclosporine A eye drop (2%) and tacrolimus eye ointment (0.03%) in management of children with refractory vernal keratoconjunctivitis. Graefes Arch Clin Exp Ophthalmol 2021; 260:353-361. [PMID: 34453603 DOI: 10.1007/s00417-021-05356-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 07/05/2021] [Accepted: 07/27/2021] [Indexed: 10/20/2022] Open
Abstract
PURPOSE To compare the effects of ciclosporine A (2%) eye drop and tacrolimus (0.03%) eye ointment on children with vernal keratoconjunctivitis (VKC) who were not responding to corticosteroid eye drops. METHODS A prospective comparative study was carried out on children who were diagnosed with refractory VKC at the ophthalmology clinic in Benha University, Delta area, Egypt, during the period from October 2019 to February 2020. RESULTS Fifty-nine patients completed this study. Regarding the individual symptom score, redness, burning, photophobia, and foreign body sensation were significantly reduced in the tacrolimus group compared to those in the ciclosporine A group during the 1st week (p < 0.05). Moreover, the tacrolimus group showed a statistically significant reduction in burning and foreign body sensation at the 4th week (both p = 0.032), and in redness and burning sensation at the 12th week compared to those in the ciclosporine A group (p = 0.005 and 0.048, respectively). The tacrolimus group showed significantly lower mean scores for tarsal conjunctival papillary hypertrophy at the 1st week and 12th week (p = 0.037 and 0.046, respectively), and for punctate erosion and cobblestone papillae at the 1st week (p = 0.029 and 0.037, respectively) than the ciclosporine group. Failure of treatment was observed in 6 patients (19.35%) in the ciclosporine A group and in 5 patients (17.85%) in the tacrolimus group. No serious side effects were detected in any group. CONCLUSION A higher reduction in inflammatory symptoms and signs as well as compliance with tacrolimus 0.03% eye ointment than with ciclosporine A 2% eye drops was observed. Moreover, long-term medication for refractory cases is needed to control inflammation. Overall, our finding suggested that ciclosporine A eye drops and tacrolimus eye ointment could be considered as corticosteroid-sparing drugs in the management of children with refractory VKC.

Abstract
Vernal keratoconjunctivitis (VKC) is a complex and chronic, multifactorial Th2 cell-mediated chronic ocular surface inflammatory condition that typically affects predominantly male children in hot or warm climates. The primary symptom is intense ocular pruritus, often significant enough to affect activities of daily living. Clinical features differ from simple forms of allergic conjunctivitis in that they are more-or-less confined to the superior tarsus and limbus. There is also a risk of corneal involvement, which leads to irreversible vision loss in approximately 6% of patients. Right now, there is no standardized treatment protocol, and many of the currently available options are not effective in severe and recurrent cases. As such, it is imperative to understand this complex allergic immune response in order to identify future therapeutic targets. This review will focus on potential drug targets in VKC, with particular emphasis on immunomodulators and immunobiologic agents.

Abstract
BACKGROUND No studies have been reported on the efficacy and safety of long-term (≥12 months) use of topical tacrolimus for refractory ocular surface inflammation in pediatric patients. METHODS Medical records of pediatric patients who were prescribed topical 0.02% tacrolimus ointment for refractory ocular surface inflammation between January of 2010 and March of 2018 were reviewed retrospectively. Changes in ocular surface signs during slit-lamp examination, clinical symptoms and concurrent steroid use were graded with a scoring system. The presence of side effects was also assessed. The changes in disease severity and patient symptoms were compared between baseline and after the treatment. RESULTS Among 72 patients (55% males, mean age 10.8 ± 3.9 years, range 3 to 17 years), 25 patients (48% males, mean age 11.4 ± 3.9 years) fully recovered, resulting in discontinuance of the ointment treatment before 12 months. Six patients experienced intolerable burning sensation, which required treatment cessation. Cessation days of those who quit were 1,5,14,20,26, and 35 days. Seven patients were lost during follow-up. Thirty-four patients (56% males, mean age 11.2 ± 4.2 years, range 3 to 17 years) were treated with tacrolimus ointment for over 12 months (average 23.1 ± 19.1 months, range 12 to 98 months). During the follow-up period, all patients showed improved clinical signs and symptoms, and no adverse reaction was noted. CONCLUSIONS Long-term maintenance of topical tacrolimus 0.02% ointment is safe and effective in improving refractory ocular surface inflammation in pediatric patients.

Abstract
Purpose: To compare the efficacy of 2% rebamipide suspension with topical cyclosporine and tacrolimus for managing vernal keratoconjunctivitis (VKC)Methods: In this prospective, interventional study, 38 patients with moderate to severe VKC were allocated to receive either 2% rebamipide in one eye and 0.03% tacrolimus ointment in the contralateral eye (n = 19) or 2% rebamipide in one eye and 0.05% cyclosporine in the contralateral eye (n = 19) for 12 weeks. Ten ocular signs and 7 symptoms were graded on a scale of 0-3 each for each eye at every visit.Results: Total sign and symptom scores reduced significantly in all 4 subgroups (all p's <0.05) at 12 weeks. Reduction of mean sign scores between rebamipide and tacrolimus (- 4.67 ± 4.63 and - 2.80 ± 3.18 respectively) and between rebamipide and cyclosporine (-6.00 ± 3.74 and -5.42 ± 3.68 respectively) was comparable. Reduction in symptom scores was also comparable between subgroups.Conclusion: Our findings suggest that efficacy of topical rebamipide is comparable to topical cyclosporine and tacrolimus for managing moderate to severe VKC and it merits further evaluation as a novel steroid sparing alternative for this disorder.

Abstract
Background and objective Tacrolimus has been widely used in recent years for treating allergic conjunctivitis, but there is currently no available meta-analysis regarding its therapeutic efficacy. This study systematically evaluated the effectiveness of tacrolimus in the treatment of allergic conjunctivitis. Methods Data obtained from literature searches of the PubMed, Cochrane Library, Embase, CNKI, and Wanfang databases were retrieved by combining medical subject words and free words. Literature was selected on the basis of established inclusion and exclusion criteria, and the extracted data were evaluated for risk of bias using RevMan 5.3 for meta-analysis. Results A total of 177 articles were retrieved, of which 5 articles were eventually selected, all of which involved tacrolimus treatment for vernal keratoconjunctivitis. A total of 203 samples were analysed. Results of the meta-analysis showed that the tacrolimus treatment group had significantly lower ocular objective sign scores (SMD −1.39, 95% CI −2.50 to −0.27; p<0.05) and had a significantly lower subjective symptom evaluation score (SMD −0.92, 95% CI −1.59 to −0.24; p<0.05) than the control group. Conclusion Current evidence shows that tacrolimus is effective in treating vernal keratoconjunctivitis.

Abstract
PURPOSE Investigation of the efficacy and safety of 12 months of topical tacrolimus 0.03% ointment treatment against the subepithelial infiltrates (SEIs) due to adenoviral keratoconjunctivitis (AKC) resisting at least 2 years was aimed. METHODS This case series included consecutive patients with SEIs secondary to AKC who were resistant to topical steroid and ciclosporin-A (CSA) treatment and treated with topical 0.03% tacrolimus (Protopic; Fujisawa Healthcare, Teva, Deerfield, Illinois, USA) for 12 months, at least 2 years after AKC. For the evaluation of treatment efficacy, best-corrected visual acuity (BCVA), Fantes score, corneal subepithelial infiltrate score (CSIS), Oxford score, Schirmer and tear breakup time results were evaluated. Intraocular pressure and complaints of the patients were followed for evaluating the safety profile of the treatment. The patients were followed after the baseline visit at the 1st, 3rd, 6th and 12th month. RESULTS 15 eyes of 11 patients with SEIs and 16 eyes of 16 healthy controls were included in this study. 1 patient (9.1%) could not tolerate the treatment. Significant improvements in BCVA, CSIS, Fantes score and Schirmer results were observed in the study group starting from the 3rd-month visit, and the improvements persisted until the end of 12 months of treatment. CONCLUSION Topical 0.03% tacrolimus might show efficacy against the SEIs persisting at least 2 years despite corticosteroid and/or CSA treatment without any prominent side effect. While at least a period of 3 months was necessary for a significant improvement in the BCVA, SEIs and Schirmer results, a period of 6 months was necessary for a decrease in Oxford score.

Abstract
PURPOSE To describe the role of combined topical cyclosporine (CsA) 0.1% and tacrolimus 0.03% in cases with severe steroid intolerant vernal keratoconjunctivitis (VKC). METHODS Medical records of patients with acute exacerbation of VKC and steroid intolerance referred from glaucoma to cornea clinic were reviewed from March 2017 to December 2018. Eleven patients (22 eyes), (nine with steroid-induced glaucoma, two with steroid-induced cataract and glaucoma) were found. All were started on topical CsA 0.1% QID. Due to suboptimal response at 2 weeks, topical tacrolimus 0.03% BD was also included. RESULTS The mean total subjective score at presentation was 13 ± 1.4, which reduced to 11.2 ± 1.3 at 2 weeks of topical CsA therapy and further reduced to 5 ± 0 at 2 weeks of combination therapy (p < 0.001). The mean total objective score at presentation was 9.4 ± 1.4 that reduced to 8.0 ± 1.3 at 2 weeks of topical CsA therapy and further reduced to 4.3 ± 1.6 at 2 weeks of combination therapy (p < 0.001). Similar results were obtained in a sub-group analysis including the worse eye or right eye of the cases only. The absolute change in the total subjective and objective score was much more with combination therapy. Photophobia and conjunctival hyperemia resolved within 4 weeks of combined therapy. No recurrence was observed till 6 months follow-up. CONCLUSIONS Combined use of cyclosporine and tacrolimus may lead to rapid resolution of symptoms and reduced recurrence rate in cases with severe VKC where steroid has to be avoided.

Abstract
The sealed anatomical features of the eye and its physiological activity that rapidly removes drugs are called anatomical and physiological barriers, which are the cause of more than 90% of drug loss. This aspect remains a critical issue in eye surface medication. Thus, promoting tissue permeability of drugs as well as prolonging their retention on the eye surface can improve their bioavailability and enhance their therapeutic effects. Thanks to the existence of a negatively charged mucin layer on the eye surface, several peptide-decorated polymeric micelles were prepared to enhance the interaction between the micelle and eye surface, thus prolonging the drug retention on the eye surface and promoting its tissue permeability. Tacrolimus (also known as FK506) is a hydrophobic macrolide immunosuppressant used to treat dry eye syndrome and other eye diseases. However, its hydrophobic nature makes its delivery as a topical eye surface medication difficult, with the risk of side effects due to overdoses. Therefore, the aim of this work is to evaluate the ability of FK506 micelles in promoting their permeability on the eye surface. Our results showed that the positively charged nanomicelles could significantly prolong FK506 retention on the eye surface and enhance its corneal permeability in ex vivo and in vivo conditions. FK506 nanomicelles exhibited superior curing effects against dry eye diseases than the FK506 suspension and a commercial FK506 formula. It exerted better inhibitory effects on eye surface inflammation and corneal epithelium apoptosis when examined by a slip lamp and a transferase-mediated dUTP nick end labeling assay, respectively. Further assays revealed the higher suppressive effects on the expression of several inflammation-related factors at an mRNA and protein level. Hence, our results suggested that these positively charged nanomicelles might be a good drug delivery system for ocular surface medication.

Abstract
OBJECTIVE The purpose of this paper is to review the efficacy and safety profile in children treated with topical 0.03% Tacrolimus ointment for vernal keratoconjunctivitis in Middle East and to propose a treatment posology. According to recent studies, a complex non-IgE dependent mechanism plays a relevant role in the pathogenesis of vernal keratoconjunctivitis. Numerous cells and mediators have been found in the serum, conjunctiva and tears of patients with Vernal keratoconjunctivitis. DESIGN This case series included 10 patients from a single centre, pediatric department of a tertiary hospital with active symptomatic vernal keratoconjunctivitis. All the patients had proliferative lesions and corneal involvement despite conventional medications, including topical steroids. All other medications, systemic and topical: steroids, antihistamines and cyclosporine, were unsuccessful. Patients were treated with topical 0.03% Tacrolimus ointment twice daily for 8 weeks and then once a day for the next two month followed by thrice a week for two months. The changes in symptoms and signs after treatment were evaluated, also the development of possible complications was assessed. RESULTS The results showed a significant reduction in signs and symptoms after 4 weeks of the treatment. Clinical resolution of giant papillae and corneal lesions were seen within eight weeks and no additional drug was required during that period, except tear substitutes. Treatment was continued for period of two months and then slowly reduced. CONCLUSION The use of 0.03% Tacrolimus ointment is safe and effective in children refractory to conventional treatment of vernal keratoconjunctivitis even in high temperature climate as Middle East. Due to the effectiveness of the treatment, the dosage used may be proposed for conventional use.

Abstract
PURPOSE To report the results of treating children with vernal keratoconjunctivitis (VKC) using a monotherapy of topical tacrolimus 0.03%. METHODS This was a prospective, nonrandomized observational study of children newly diagnosed with VKC. The severity of the disease was graded on a 4-point scale of symptoms and signs. Patients were treated with tacrolimus 0.03% ointment and were followed for 8 months according to a schedule based on the severity of the disease. The primary measure of treatment efficacy was the change in the score of objective signs. The incidence and severity of adverse events, if any, were recorded. RESULTS A total of 45 children aged 5-15 years were enrolled. The mean composite symptom score was 6.84 ± 2.26 at baseline and 0.71 ± 1.62 at 8 months, a statistically significant reduction (P < 0.001). The mean composite sign score was 9.6 ± 3.14 at baseline and 1.16 ± 1.28 at 8 months, also a statistically significant reduction (P < 0.001). Four patients had to be started on steroids within the first month of treatment and were considered treatment failures. Thus, 89% of patients showed significant improvement. No participant experienced adverse effects, although some reported a transient stinging sensation. CONCLUSIONS In our study cohort topical tacrolimus ointment 0.03% as a monotherapy for VKC was successful in the majority of subjects, and there was no adverse effect.

Abstract
Allergic conjunctival granuloma is a rare cause of conjunctival ocular lesions. The aim of this case report was to present a successful treatment of an allergic conjunctival granuloma with topical tacrolimus eye drops. A 20-year-old female presented with bilateral multiple yellow nodules of the bulbar conjunctival epithelium and conjunctival injection. The patient had tearing, photophobia, itching, foreign body sensation, and red eye. The patient's signs and symptoms progressed despite the use of topical steroids. The patient was treated by application of tacrolimus eye drop (0.005%) in her right eye every 6 h while the left eye was put on placebo. Her signs and symptoms were recorded at each visit. After 3 weeks' therapy with topical tacrolimus eye drop, the patient became asymptomatic in her right eye and conjunctival granulomas fully resolved. Topical tacrolimus seems to be an effective therapeutic option for the treatment of allergic conjunctival granulomas.

Abstract
Severe allergic ocular diseases as atopic keratoconjunctivitis can induce corneal damage due to inflammatory substances released from giant papillae. Tacrolimus eye drops are one of the current therapeutic alternatives for its treatment. This work is aimed at developing and characterizing a 0.03% tacrolimus ophthalmic formulation, which was introduced in three types of vehicles (BBS, PVA and Hyaluronic Acid). For this, we have performed in vitro (stability studies) and in vivo assays (corneal permanence time measured directly by Positron Emission Tomography) of three potential formulations. Next, the best formulation was selected, and its toxicological profile and clinical effectiveness have been evaluated. The biopermanence studies (direct measurements and PET/CT) showed that the formulations with PVA and Hyaluronic Acid present more retention time on the ocular surface of rats than PBS. From the stability study, we have determined that tacrolimus with PVA in cold storage is the best option. Tacrolimus with PVA has shown lower cytotoxicity than cyclosporine at early times. On the other hand, the pilot study performed has shown significant improvements in patients, with no noticeable adverse reactions. Based on stability, biopermanence, safety and clinical effectiveness studies, we concluded that tacrolimus-PVA eye drops are a suitable candidate for its clinical application in inflammatory ophthalmology diseases.

Abstract
PURPOSE Vernal keratoconjunctivitis (VKC) is a bilateral, chronic, external ocular inflammatory disorder that mainly affects patients in their first or second decade. This study was designed to compare tacrolimus and interferon alpha-2b (IFN alpha-2b) eye drops in the treatment of VKC. METHODS In this randomized, double-masked clinical trial, 40 consecutive patients with VKC were sent to a referral eye hospital in a tropical region southeast of Iran. Patients were randomly assigned to receive either 0.005% tacrolimus or IFN alpha-2b (1,000,000 units/cc). Chi-square and t tests were used for comparison of outcomes between both groups. RESULTS Mean ± SD age was 11.1 ± 5.2 years. Thirty-one patients (77.5%) were male. The mean duration of disease was 3.4 ± 2.9 years. In this study, the signs and symptoms were significantly reduced in patients after treatment in both groups (P = 0.0001). In the tacrolimus group, all patients responded to treatment whereas only one subject in the IFN group failed to respond (P = 0.99). Side effects in both groups were mild and tolerable. CONCLUSIONS This study indicated that both 0.005% tacrolimus and IFN alpha-2b are effective and appear to be safe in treatment of recalcitrant VKC.

Abstract
The aim of this study was to investigate the mechanisms of combination treatment with FK506 and natamycin on alleviating damage of the cornea in mouse model of fungal keratitis. In this study, the mouse model of fungal keratitis was created by intrastromal injection with Fusarium solani or Aspergillus flavus. The mice received 5% natamycin eye drops 6–8 times a day, or the mice received 0.05% FK506 eye drops 2 times per day for 21 consecutive days. Corneal damage was evaluated by H&E staining. The protein expression levels of NLRP3 were detected by immunohistochemistry. Moreover, the markers of inflammasome activation including NLRP3, ASC, caspase-1, IL-1β, and IL-18 were detected by western blot. Histopathological results showed increased corneal thickening, dense inflammatory cell infiltration, and loss of epithelial continuity in the corneas after fungal infection. In addition, NLRP3 positive signals were observed to be obviously increased in the corneas after A. flavus or F. solani infection compared to the control group. Furthermore, the NLRP3 inflammasome is induced by fungal infection, as evidenced by increased protein expression levels of NLRP3, ASC, caspase-1, and downstream cytokines, such as interleukin (IL)-1β and IL-18. However, the corneal damage was alleviated and the activation of the NLRP3 inflammasome was significantly inhibited by drug treatment. Besides, the treatment outcomes were better in combined treatment group than that in single-agent treatment group. In conclusion, FK506 combined with natamycin alleviate fungi-induced corneal damage by suppressing NLRP3 inflammasome activation.

Abstract
Lipopolysaccharide (LPS)-induced keratitis is a progressive infectious ocular disease in which innate inflammatory responses often cause clinical tissue damage and vision loss. The present study aimed to investigate the effects of tacrolimus, an effective immunomodulator, on LPS-induced innate immune responses. The effects of tacrolimus on the apoptotic rate and viability of human corneal epithelial cells (HCECs), polymorphonuclear neutrophils (PMNs) and monocytes (THP-1 cells) were examined using flow cytometry and MTT assays. Subsequently, the role of tacrolimus on LPS-induced inflammation in HCECs, PMNs and THP-1 cells was evaluated by detecting the expression levels of pro-inflammatory cytokines, including interleukin (IL)-1β, IL-6 and matrix metallopeptidase 9; anti-inflammatory cytokines, including IL-10 and transforming growth factor-β; and proangiogenic factors, including vascular endothelial growth factor and tumor necrosis factor-α using quantitative polymerase chain reaction. The results demonstrated that tacrolimus had good biocompatibility with HCECs, while promoting apoptosis and decreasing the viability of PMNs and THP-1 cells. Furthermore, tacrolimus effectively reduced the expression levels of pro-inflammatory cytokines and increased anti-inflammatory cytokines in LPS-induced keratitis in vitro. Notably, tacrolimus decreased the levels of proangiogenic factors, which are highly increased following LPS stimulation. Conclusively, tacrolimus appears to be a safe and effective treatment to suppress neutrophil and monocyte activity, modulate the balance of pro-/anti-inflammatory cytokines, and reduce the inflammatory response and angiogenic activity in LPS-induced bacterial keratitis.

Abstract
Immune mediated inflammatory anterior segment diseases are variable and their management requires intense immunosuppression. Treatment with topical steroids is associated with serious ocular side effects. In order to overcome the potentially blinding complications of topical steroids, immunomodulatory drugs are being used more frequently. Tacrolimus is a calcineurin inhibitor that induces suppression of T lymphocytes activity and reduction of ocular inflammation. Tacrolimus was recently investigated for application in various anterior segment inflammatory disorders. In this review, we will discuss the therapeutic application of topical tacrolimus as a steroid-sparing agent in treating T cell mediated anterior segment inflammation.

Abstract
PURPOSE: To evaluate the safety and efficacy of 0.003% tacrolimus suspension for the treatment of refractory vernal keratoconjunctivitis (VKC). MATERIALS AND METHODS: This prospective study included 40 eyes of 20 patients with severe VKC. After discontinuing all other medications, patients were treated with varying doses of 0.003% tacrolimus suspension. All were followed for at least 24 months. Changes in signs and symptoms after treatment were evaluated; adverse events were assessed. The clinical response to the treatment was the most important measurement to achieve the conclusion. RESULTS: The mean age of the patients was 15.7 ± 1.4 years. Two patients discontinued treatment due to severe burning sensation and were excluded from the study. Significant improvements in all signs and symptoms, including itching, foreign body sensation, papillae, and Trantas dots, were seen in all patients 6 weeks after starting topical tacrolimus. Itching was the first symptom to improve. Treatment was gradually reduced, and intervals were increasing between applications. Recurrence occurred in all patients who attempted to discontinue treatment. No additional medications were required to provide relief, and no significant changes in visual acuity or refraction were seen. CONCLUSIONS: The safety and efficacy of 0.003% Tacrolimus suspension treatment for refractory VKC were achieved and it can be considered a useful option instead of steroids, despite the poor compliance in few patients due its adverse effects.

Abstract
Dry eye disease (DED) is a multifactorial disease of the tears and ocular surface that causes tear film instability with potential damage to the ocular surface. The prevalence of dry eye in the world population ranges from 6 to 34 %. It is more common in those aged over 50, and affects mainly women. Since the introduction of the Schirmer's test in 1903, other tests have been developed to evaluate dry eye, such as biomicroscopy, the tear film breakup time (BUT), vital dyes (lissamine green and rose bengal), fluorescein, leaf fern test, corneal sensitivity test, conjunctiva impression cytology, optical coherence tomography (OCT), and tear osmolarity measurement. Although there is no gold standard, it is advisable to combine at least two tests. Strategies for treating DED have recently been modified and include patient education, tear substitute, corticosteroids, secretagogues, fatty acids, immunomodulators, occlusion of lacrimal puncta surgery and, tarsorrhaphy. Biological therapy and new topical immunomodulators such as tacrolimus, tofacitinib and IL-1 receptor inhibitor are being tested. In this review, the evaluation tests for dry eye are compared and the main studies on treatment are presented, with emphasis on studies in patients with Sjögren's syndrome. The authors propose an approach for the management of dry eye.

Abstract
INTRODUCTION Allergic Ocular Diseases (AODs) like Atopic Keratoconjunctivitis (AKC) and Vernal Keratoconjunctivitis (VKC) are chronic forms of ocular allergy that can cause severe visual complications. Pathogenesis of AODs is uncertain and treatment has been a challenge for ophthalmologists. Tacrolimus, a 23-member cyclic macrolide lactone derived from [streptomyces tsukubaensis] now in ointment form has been successfully used in AODs. AIM To study the therapeutic effect of 0.1% Tacrolimus eye ointment in patients with Allergic Ocular Diseases (AODs). MATERIALS AND METHODS This prospective observational study was conducted on 36 patients with severe AOD and moderate cases not responding to conventional treatment. They were treated with 0.1% tacrolimus eye ointment twice daily for minimum three months in addition to conventional treatment and observed for a period of 6 months. Symptoms and signs after treatment were evaluated. Grades of clinical signs were assessed based on slit lamp clinical photographs; development of possible complications was assessed and analysed by Wilcoxon signed rank test. RESULTS Mean age of patients was 9.3±4.3 years and mean duration of AODs was 3.1±1.8 years. The scores on both the four point scales for signs and symptoms decreased significantly (p<0.0001) after 1 month of 0.1% Tacrolimus eye ointment treatment. Itching was the first symptom to show dramatic relief and conjunctival hyperaemia was the first sign to show improvement. 88.88% of patients were successfully weaned off topical steroids in 6 months into Tacrolimus treatment. Even in patients unresponsive to 0.1% topical Cyclosporine, symptoms and signs scores decreased significantly (p<0.0001). The most common adverse reaction was a transient burning sensation (36.11%). CONCLUSION Topical 0.1% Tacrolimus eye ointment was found to be a safe and effective treatment in cases of AODs and also worked as steroid sparing and replacing agent. It was also found effective in patient's refractory to topical Cyclosporine.

Abstract
PURPOSE To evaluate the safety and efficacy of topical tacrolimus 0.05% versus topical methylprednisolone 0.5% in patients with ocular graft-versus-host disease (GVHD). DESIGN Phase 1/2 prospective, randomized, double-masked clinical trial. PARTICIPANTS Eighty eyes of 40 patients diagnosed with chronic ocular GVHD were enrolled. METHODS Forty patients with ocular GVHD were randomized; 24 patients were treated with topical tacrolimus 0.05% and 16 patients were treated with topical methylprednisolone 0.5% twice daily for 10 weeks, in addition to continuing their baseline treatment regimen. MAIN OUTCOME MEASURES Safety was evaluated based on occurrence of adverse events. Tolerability was assessed based on subject reports of discomfort after drop instillation. Intraocular pressure (IOP) was monitored. The main efficacy end points were corneal fluorescein staining (CFS), tear film break-up time (TBUT), Schirmer test results, and expression of the ocular surface inflammatory markers human leukocyte antigen-DR (HLA-DR) and intercellular adhesion molecule-1 (ICAM-1). Symptoms were evaluated using the Ocular Surface Disease Index (OSDI). RESULTS After 10 weeks of treatment, no major adverse events occurred in either treatment group, and there was no significant difference in the composite tolerability scores between the 2 groups (P = 0.06). However, burning sensation was more pronounced with tacrolimus (P = 0.002). Topical tacrolimus was more effective than methylprednisolone in reducing the CFS score at week 10 (55% vs. 23% reduction, respectively; P = 0.01) and achieved significant improvement in TBUT when compared with baseline (P < 0.001). Reduction in OSDI score achieved statistical significance with tacrolimus (27% reduction; P = 0.02), but was marginal with methylprednisolone (32% reduction; P = 0.06). Expression of ICAM-1 by ocular surface epithelium decreased significantly in both groups (tacrolimus, P = 0.003; methylprednisolone, P = 0.008), whereas HLA-DR expression decreased significantly only in the tacrolimus group (P = 0.03). Schirmer test scores did not change significantly in either group during the study; IOP increased significantly with methylprednisolone at week 10 (P = 0.04). CONCLUSIONS Topical tacrolimus 0.05% is safe, generally well tolerated, and effective for the treatment of ocular GVHD without the hypertensive effects of topical corticosteroids.

Abstract
Objective The objective of this study was to evaluate the efficacy and safety of topical low-dose tacrolimus (0.01%) solution in patients with vernal keratoconjunctivitis (VKC). Patients and methods A total of 62 consecutive patients with VKC refractory to conventional treatment were included retrospectively. Tacrolimus 0.01% ophthalmic solution was administered to patients twice daily after discontinuation of all previous topical medications. The duration of treatment ranged from 1 month to 29 months. The clinical symptoms of itching, redness, foreign body sensation, and discharge and the clinical signs of conjunctival hyperemia, conjunctival papillary hypertrophy, limbal infiltration, Trantas dots, and superficial punctate keratopathy were graded as 0 (normal), 1+ (mild), 2+ (moderate), or 3+ (severe). Assessment was carried out before initiation of therapy and on the last visit after treatment. Results There were 62 patients with VKC comprising 49 male and 13 female patients. The median age was 12 years (range: 5–47 years). The mean visual acuity improved from 20/30 to 20/25 following treatment. There was statistically significant improvement in symptoms of itching (P<0.001), redness (P<0.001), foreign body sensation (P<0.001), and discharge (P<0.001). Statistically significant improvement was also observed in clinical signs of conjunctival hyperemia (P<0.001), limbal infiltration (P<0.001), Trantas dots (P<0.001), superficial punctate keratopathy (P<0.001), and conjunctival papillary hypertrophy (P<0.001). The solution form of tacrolimus was well tolerated. None of the patients developed elevation of intraocular pressure, cataract, or infectious keratitis. Conclusion Low-dose topical tacrolimus 0.01% solution is effective and safe in the management of patients with refractory VKC.

Abstract
Allergic conjunctivitis is one of the most common allergic conditions worldwide. Its incidence is increasing due to changing climate, pollution, increased pollen loads, and the subject's heightened immunological sensitivity in response to these environmental changes. The pathophysiology predominantly involves immunoglobulin E-related mast-cell activation, with release of histamine and other mediators contributing to the propagation of the response by calling in other immune cells and further inflammation. This article presents the evolution of ocular allergy treatments, from vasoconstrictors, to antihistamines and mast-cell stabilizers, to the dual-acting agents, as well as corticosteroid and immunomodulatory options. Future targets for allergy treatment are also discussed.

Effect of Topical Tacrolimus in the Treatment of Thygeson's Superficial Punctate Keratitis. Am J Ophthalmol 2015; 160:663-8. [PMID: 26133248 DOI: 10.1016/j.ajo.2015.06.019] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2015] [Revised: 06/20/2015] [Accepted: 06/22/2015] [Indexed: 11/22/2022]
Abstract
PURPOSE To evaluate topical tacrolimus ointment for treating Thygeson's superficial punctate keratitis (Thygeson SPK). DESIGN Retrospective interventional case series. METHODS setting: Institutional practice. PATIENT POPULATION The medical records of 14 patients (9 women; age range, 9-65 years) with Thygeson SPK were reviewed retrospectively. Diagnosis was based on the history and clinical examination. INTERVENTION Patients were treated with tacrolimus 0.03% eye ointment instilled into the lower fornix twice daily for the first 2 weeks, followed by nocturnal application. The clinical signs and symptoms were assessed after 1 month of treatment. The drug was tapered with disease improvement. MAIN OUTCOME MEASURE(S) Treatment efficacy and side effects. RESULTS All patients had bilateral disease (average duration, 6 years). All patients, except 2 who used the medication irregularly, had improved visual acuity (VA), symptoms, and signs as long as the medication was applied. Before treatment 28.57% of patients had VA between 20/30 and 20/50, with improvement after treatment to 20/25 or 20/20. Attempts to withdraw the medication resulted in recurrent disease, and, therefore, treatment was not curative during the study period. No significant local medication side effects were reported. CONCLUSION Tacrolimus eye ointment 0.03% was effective for controlling Thygeson SPK for a long period with good patient tolerance and no noticeable local or systemic side effects. During the average 6-year follow-up, treatment was not curative. Randomized studies are difficult to conduct because of the disease rarity.

Abstract
PURPOSE OF REVIEW Allergic eye diseases comprise a spectrum of diseases, with each condition being characterized by a complex immunopathology. The more severe and chronic conditions, such as vernal keratoconjunctivitis and atopic keratoconjunctivitis, involve predominantly mast cells and eosinophils, while also being associated with a preponderance of T cells. Treatment with topical antihistamines or mast cell stabilizers is often unsatisfactory, and therapy depends on topical corticosteroids. Corticosteroids have significant side-effects with long-term use; therefore, they appear to be more appropriate for short-term pulse therapy. Immunomodulatory agents can also be used to inhibit T-cell activation and show encouraging results among patients with severe allergic eye conditions. The present review is an attempt to present a coherent picture of the recent investigations of topical immunomodulatory agents' therapy in severe allergic eye diseases, especially cyclosporine A and tacrolimus, and their mechanisms of action. RECENT FINDINGS Immunomodulatory agents are commonly indicated for the treatment of severe and prolonged allergic conjunctivitis. This article reviews the recent studies of these drugs and the development of immunomodulatory treatments for severe allergic eye diseases. SUMMARY Cyclosporine A and tacrolimus are currently available for the treatment of severe allergic conjunctivitis. These agents have led to improved therapeutic results for patients with severe and chronic allergic eye diseases.

Abstract
PURPOSE To describe the use of topical 0.03% tacrolimus in patients with symptomatic corneal subepithelial infiltrates (SEIs) secondary to adenoviral keratoconjunctivitis (AK) that were resistant to tapering of corticosteroid eye drops. METHODS This was a prospective, nonrandomized, noncomparative interventional case series that included consecutive patients treated with tacrolimus for resistant SEIs after AK. The patients had active SEIs and corrected distance visual acuity (CDVA) of 20/25 or worse when treatment was initiated. The recorded data included age, sex, CDVA, intraocular pressure, duration and intensity of symptoms, biomicroscopy findings, and duration of therapy. The treatment was considered successful if there was a reduction in SEIs, as well as CDVA stabilization or improvement. The treatment was considered unsuccessful if the patient could not tolerate tacrolimus or if there was an increase in SEIs. RESULTS Seven patients were included (10 eyes). The mean age was 36.7 ± 12.3 years. The mean duration of tacrolimus therapy was 8.8 ± 2.4 months, and the mean duration of follow-up was 13.6 ± 10.7 months. Treatment was successful in 8 eyes of 6 patients. One patient could not tolerate the medication. Statistically significant improvement in the CDVA was observed (from a mean of 0.29 to 0.07) (P = 0.001). No statistically significant changes in the intraocular pressure were observed (P = 0.574). SEI scores showed a significant reduction from 2.20 ± 0.92 to 0.25 ± 0.46 (P = 0.011). All patients who completed treatment had improvement in ocular symptoms. CONCLUSIONS Topical 0.03% tacrolimus seemed to be an effective corticosteroid-sparing agent for the treatment of SEIs after AK.

Abstract
INTRODUCTION Topical calcineurin (Cn) inhibitors delivered via ophthalmic drop is emerging as a potential treatment for severe, immune-mediated forms of allergic conjunctivitis, such as vernal keratoconjunctivitis, atopic keratoconjunctivitis and giant papillary conjunctivitis. AREAS COVERED This article is based on a comprehensive literature search, with information taken from meta-analyses, systematic reviews, treatment guidelines and clinical studies in children and adults. The articles that have been selected evaluate the use of topical Cn inhibitors and their role in the treatment of allergic conjunctivitis. EXPERT OPINION Ophthalmic topical Cn inhibitors have been shown to be safe for short-term use, with minimal systemic absorption and toxicity. For patients with severe, refractory forms of allergic conjunctivitis, topical Cn inhibitors offer a promising treatment option and an alternative to steroidal therapies. The safety profile and efficacy data for topical cyclosporine are more robust compared to that of tacrolimus and pimecrolimus, although larger trials will be needed for all three agents. With more randomized controlled trials involving larger sample sizes and long-term follow-up to establish both efficacy and safety, ophthalmic Cn inhibitors offer exciting treatment possibilities for the prevention of morbidity associated with refractory allergic conjunctivitis.

Abstract
PURPOSE To evaluate the long-term clinical outcomes of 0.1% tacrolimus dermatologic ointment (Protopic) in cases of refractory atopic keratoconjunctivitis (AKC). DESIGN Prospective, nonrandomized, noncontrolled case series. METHODS Twenty-two eyes from 11 patients with severe AKC who were treated with 0.1% tacrolimus ointment were followed prospectively. The mean age of the patients was 32.27 ± 12.7 years (range, 19-61 years). Each patient completed a follow-up period of at least 48 months, during which the signs and symptoms of AKC were assessed. Changes in the total scores of signs and symptoms from baseline were recorded at each visit, and the main outcome measure was the clinical response to topical tacrolimus treatment. RESULTS Dramatic improvements in clinical signs and symptoms were achieved 1 week after starting topical tacrolimus treatment, and complete clinical resolution was observed in almost all patients 6 weeks after starting treatment. Treatment was gradually reduced, with increasing intervals between applications. Eight patients remained asymptomatic for up to 3 years, although recurrence occurred in 3 patients who attempted to discontinue treatment. All patients complained of a mild burning sensation upon application of the ointment. No additional medications were required to provide relief, and no patient discontinued treatment because of adverse drug effects. No drug-related ocular complications were encountered, and no significant changes in visual acuity or refraction were documented. CONCLUSIONS Tacrolimus dermatologic ointment is a potentially safe and effective treatment for AKC cases refractory to standard treatment and may substitute for steroid treatments aimed at controlling disease activity.
