Abstract
Vernal keratoconjunctivitis (VKC) is an underdiagnosed and underrecognized ocular surface disease with limited epidemiological data in Asia. It is more prevalent in warm, dry, and windy climates, and often has a substantial impact on a patient's quality of life. In rare cases, VKC can be associated with vision loss, either through corticosteroid overuse or inadequate treatment of persistent inflammation. As a potentially severe and complex disease, there is variability with how VKC is managed across Asia and among the various allergic eye diseases. Diagnosis and treatment of patients with VKC is a challenge for many ophthalmologists, since no precise diagnostic criteria have been established, the pathogenesis of the disease is unclear, and anti-allergic treatments are often ineffective in patients with moderate or severe disease. In addition, the choice of treatment and management strategies used for patients varies greatly from country to country and physician to physician. This may be because of a lack of well-defined, standardized guidelines. In response, the Management of Vernal Keratoconjunctivitis in Asia (MOVIA) Expert Working Group (13 experts) completed a consensus program to evaluate, review, and develop best-practice recommendations for the assessment, diagnosis, and management of VKC in Asia. The expert-led recommendations are summarized in this article and based on the currently available evidence alongside the clinical expertise of ophthalmologists from across Asia with specialism and interest in the ocular surface, VKC, and pediatric ophthalmology.

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
PURPOSE To investigate whether crude house-dust-mite antigen exacerbates eosinophilic inflammation in the conjunctival tissues of an atopic keratoconjunctivitis mouse model in a dose-dependent manner. MATERIALS AND METHODS An atopic keratoconjunctivitis mouse model was established by percutaneous sensitization and crude house-dust-mite antigen application in NC/Nga mice. To assess the dose-dependent response, conjunctival specimens from groups that were administered high- (High-HDM) or low-dose house-dust-mite antigen (Low-HDM) following percutaneous sensitization and the control without house-dust-mite antigen administration (control group) were evaluated. Histological examination and immunofluorescence staining were performed to determine eosinophil density and the number of IL-13-positive cells. Polymerase chain reaction array was used to obtain adaptive and innate immunity-related factor profile, and quantitative polymerase chain reaction was used to determine Il13, Il17a, Ccl11, and Ccl24 expression. Atopic keratoconjunctivitis model mice injected with anti-IL-1α antibody (IL-1α group) or vehicle (vehicle group) to the upper and lower eyelids before atopic keratoconjunctivitis development were evaluated. RESULTS Eosinophil density in the conjunctiva increased with house-dust-mite antigen application in a dose-dependent manner. CD4, CXCL10, CCR6, C3, and IL-13 mRNA levels increased more than 5-fold in the conjunctiva of the High-HDM group animals compared to those in control animals. mRNA expression of Il13 and Ccl11 in the conjunctiva of the High-HDM group animals significantly increased compared with that in the Low-HDM and control group animals. Conversely, the eosinophil density and Il13 mRNA expression significantly decreased in the IL-1α group compared with those in the vehicle group. CONCLUSIONS The house-dust-mite antigen increased eosinophilic infiltration and Il13 mRNA expression in the conjunctiva of an atopic keratoconjunctivitis mouse model in a dose-dependent manner. These inflammatory alterations were partially alleviated by eyelid injection of anti-IL-1α antibody. These findings indicate that IL-1α-induced IL-13 production constitutes a major exacerbating factor for house-dust-mite antigen-induced atopic keratoconjunctivitis.

Abstract
Vernal keratoconjunctivitis (VKC) is a chronic, bilateral, allergic conjunctivitis with episodes of acute exacerbations. Although VKC has a self-limiting course, chronic recurrent inflammation can cause long-term visual impairment due to corneal complications including shield ulcers, infectious keratitis, keratoconus, corneal opacities, and limbal stem cell deficiency. The initial step in the management of corneal involvement is medical treatment of the acute stage of VKC and prevention of recurrences. Giant papillae not responding to medical treatment can be removed surgically in the case of corneal involvement. Shield ulcer with no inflammatory plaque usually heals with appropriate medical therapy. For shield ulcer with inflammatory plaque, however, surgical debridement with or without amniotic membrane transplantation might be necessary. Keratoconus may develop in chronic and severe VKC. An annual evaluation of these patients with corneal topography and/or tomography is essential for early detection of keratoconus and its timely management that includes collagen cross-linking and intrastromal corneal ring segment implantation. Corneal transplantation may be required in the advanced stage of keratoconus. Both penetrating keratoplasty and deep anterior lamellar keratoplasty can result in excellent visual outcomes in keratoconic eyes with concomitant VKC. Appropriate management of inflammation in the perioperative period is crucial for achieving successful outcomes after corneal transplantation. Limbal stem cell deficiency, a rare complication of long-standing and severe VKC, might be treated with living-related conjunctival limbal allograft.

Abstract
PURPOSE To describe the clinical features, risk factors, and treatment outcomes after supratarsal injection of triamcinolone for vernal keratoconjunctivitis (VKC). METHODS A retrospective review of all patients treated with supratarsal triamcinolone for VKC between February 2002 and May 2017 at the Royal Victoria Eye and Ear Hospital and Our Lady's Children Hospital Crumlin, Dublin, Ireland, was performed. RESULTS Twenty-five patients, 46 eyes, and 145 injections were included for analysis. The mean age at first injection was 9.1 ± 5.7 years. Ninety-six percent of the patients were male. A seasonal variation was noted, with 59 injections (41%) of triamcinolone administered for acute and refractive cases of VKC in the summer compared with 35 (24%), 35 (24%), and 16 (11%) in the spring, autumn, and winter months, respectively. The most common presenting complaint was red eye, which was seen in all cases. Hay fever (64%) was the most common associated systemic disease. Each eye required, on average, 3.2 injections (range 1-9 injections), and the mean duration from the onset of symptoms to final treatment was 3.03 years (range 0-7.9 years). The mean presenting and final visual acuities were 0.33 and 0.11 logarithm of the minimum angle of resolution, respectively (P < 0.0001). During our study period, no patient experienced intraocular pressure rise requiring treatment, development of lenticular opacity, or ptosis after supratarsal injection of triamcinolone. CONCLUSIONS In this case series, supratarsal triamcinolone was used in cases of VKC in which topical medications had failed to control the disease process. All patients reported improvement after treatment. There were no cases of intraocular pressure rise, lenticular opacity, or ptosis development after treatment.

Abstract
Introduction Vernal keratoconjunctivis (VKC) is a severe form of pediatric ocular allergy, characterized by acute and chronic corneoconjunctival inflammation that may lead to visual sequelae. Although topical immunosuppressive drugs such as cyclosporine are usually effective, some severe forms may be refractory and require prolonged steroid therapy. Very few papers report the use of omalizumab in VKC in the literature. In the present study, we describe our clinical experience with omalizumab in severe VKC children. Methods We retrospectively reviewed the files of four boys treated with omalizumab because of severe VKC, defined as persistent corneal inflammation despite continuous topical 2% cyclosporine and steroid eye drops. We also performed a literature review. Results Four boys, aged 7–13 years old, were treated. All children had asthma and one had severe lid eczema. Two patients had required intrapalpebral depot-steroid injections. Omalizumab was administered every 2 weeks by subcutaneous injections, at doses varying from 450 to 600 mg per injection. Three patients out of four responded to the treatment, with a decrease in global symptoms (median symptom rating decreasing from 89 to 29 on a 100-mm visual analog scale), frequency and in duration of the inflammatory flares, and also a decreased need for topical steroid. Their median clinical grade decreased from 4 to 3 (Bonini grading). However, the response was incomplete and they still had inflammatory corneoconjunctival flares despite continuous topical cyclosporine. On the other hand, asthma and lid eczema were completely controlled in these three patients. The fourth child did not respond to omalizumab and needed oral steroids for his VKC and his asthma. Noticeably, this latter patient did not have detectable sensitization to any allergen, contrary to the other cases. The treatment was stopped in this refractory case, but is still ongoing in all other cases, with a median duration of 33 months (range 16–42 months). In the literature (four cases), omalizumab may have a more complete efficacy in some cases, but the results are still variable. Conclusion Omalizumab is an interesting treatment in severe refractory forms of VKC, but its efficacy is incomplete in these very severe cases.

Abstract
Severe, refractory tarsal conjunctival chemosis developed in a severely autistic 9-year-old boy with a history of allergic conjunctival chemosis. The child was initially treated with topical and oral antihistamines, topical steroids, lubricants, and topical phenylephrine 10% with worsening of condition until complete eyelid eversion secondary to gross conjunctival chemosis with total obstruction of vision in the affected eye. Subsequently, he was successfully treated with topical adrenaline (1:1000) with rapid and lasting effect. The authors suggest that topical (1:1000) adrenaline is an effective therapy when other conservative therapies fail and can be useful in avoiding examination under general anesthetic and invasive intervention. Such a case has not been previously reported in the literature.

Abstract
INTRODUCTION Allergy is the fifth leading group of chronic diseases, affecting as much as 40% of the first-world population. Its pathophysiology has a genetic component, and is driven by the immune system's sensitized response to antigens and environmental factors. As research continues to uncover the mediators responsible for ocular allergy, the development of novel drugs should progress. AREAS COVERED A literature review of allergic conjunctivitis, ocular allergy and their treatment was performed using PubMed and Medline. Additional information is also included from clinicaltrials.gov and associated web sites for drugs currently in clinical trials. EXPERT OPINION The initial step of therapy remains identification and avoidance of allergic triggers. The mainstay of treatment is the new generation of dual-acting antihistamines. Drugs that improve the magnitude and duration of relief, with greater subject responder rates, are gradually making their way into the clinic. Allergic conjunctivitis is a relatively easy disease to study because of the availability of models such as the conjunctival allergen challenge. New classes of drugs that target inflammatory pathways or mediators involved in the early and late-phase allergic response are being screened in these models and we are making progress in identifying the next generation of anti-allergic therapy.

Abstract
A 6-year-old Thai girl presented with itching, redness and copious discharge in both eyes. Slit-lamp biomicroscopy of the left eye revealed cobblestone papillae with marked ptosis while in the right eye only small papillae were observed. Punctuate epithelial keratitis was noted only in the left eye. There were no associated factors for giant papillary conjunctivitis (ie, suture or contact lens). The cobblestone papillae in the left eye persisted after maximal topical and oral antiallergic medications. Two doses of supratarsal corticosteroid (20 mg of triamcinolone acetonide) injection without any topical or oral antiallergic medications were undertaken in the left eye 1 month apart. Cobblestone papillae and punctate epithelial erosion (including allergic symptoms) were completely recovered. There was no recurrence after 18 months of follow-up. This case report indicates that using supratarsal corticosteroid injection by itself in recalcitrant vernal keratoconjunctivitis provides promising results.
