Background: Atopic keratoconjunctivitis (AKC) and vernal keratoconjunctivitis (VKC) are chronic inflammatory allergic diseases that are associated with some common conjunctival and corneal complications.1 The clinical corneal manifestations of both entities may include superficial punctate keratitis, macroerosions, corneal ulceration, plaque formation, corneal neovascularization, and lipid infiltration.

Purpose: To quantitatively evaluate the early ocular surface inflammation before and after mitomycin C (MMC)-aided papillary resection in severe allergy patients with corneal complications.

Purpose: Tryptase that is released by mast cell degranulation has recently been thought to play a key role in wound healing in allergic bronchitis. Conjunctival fibroblasts secrete mediators and extracellular matrices that could exacerbate inflammation and papillary formation in allergic conjunctivitis. This study was conducted to investigate the effect of tryptase on the proliferation of conjunctival fibroblasts and studied whether this effect was mediated by protease-activated receptor (PAR)-2.

Purpose: To describe MUC5AC alterations and the ocular surface disorder in atopic patients with or without corneal ulcers.

Methods: Atopic patients' eyes were divided into two groups according to the presence and absence of corneal ulceration. The subjects underwent corneal sensitivity measurements, Schirmer test, tear film break-up time (BUT), fluorescein and Rose Bengal staining of the ocular surface and conjunctival impression cytology and brush cytology.

Purpose: To describe tear function, mucin alterations, and ocular surface disorder in patients with atopic diseases.

Methods: Subjects underwent corneal sensitivity measurements, Schirmer test, tear film break-up time (BUT) assay, and fluorescein and rose Bengal staining of the ocular surface. Conjunctival impression cytology and brush cytology were also conducted.

The cornea is a transparent tissue of the eye, which is responsible for the refraction of incoming light. Both biological corneal equivalents and synthetic keratoprostheses have been developed to replace donor tissue as a means to restore vision. However, both designs have drawbacks in terms of stability and biocompatibility.

Setting: Minamiaoyama Eye Clinic, Tokyo, Japan.

Methods: Forty-four eyes of 32 Japanese patients and 1 Korean patient with high myopia had Artisan Myopia lens implantation to correct their refractive errors.

Giant papillary formation containing newly formed vessels is a major characteristic of severe allergic conjunctivitis, such as atopic keratoconjunctivitis (AKC) or vernal keratoconjunctivitis (VKC). We examined production of vascular endothelial growth factor (VEGF) from cultured conjunctival fibroblasts from normal volunteers under stimulation with type 1-, type 2-helper T cell derived and proinflammatory cytokines to investigate the mechanism of giant papillae formation in AKC/VKC. Primary cultured conjunctival fibroblasts were incubated with interleukin (IL)-4, IL-13, IL-1beta, IL-2, tumor necrotizing factor (TNF)-alpha, interferon (IFN)-gamma, or transforming growth factor (TGF)-beta1.

Purpose: To investigate the histopathological features of epithelial ingrowth after laser in situ keratomileusis (LASIK).

Methods: Five epithelial ingrowth specimens of 4 patients (2 to 17 months after initial LASIK) were examined. The lesions were surgically removed and examined using light and transmission electron microscopy.

Purpose: To establish the risk of ocular rupture after proposed surgical reversal of presbyopia by anterior ciliary sclerotomy (ACS) or by the Er:YAG laser (HOYA Continuum, Tokyo, Japan).

Methods: A total of 45 pig eyes (15 control eyes) were examined. Fifteen eyes were placed into one of two study groups and another 15 eyes were used as controls.

Case Report: A 27-year-old male patient with a corneal ulcer associated with AKC persistent for 6 months despite conventional treatment underwent amniotic membrane patching. On removal of the amniotic membrane patch after 1 week, the corneal ulcer that had been persistent for 6 months had healed completely.

Purpose: To evaluate the efficacy and safety of laser in situ keratomileusis (LASIK) in patients with severe dry eye associated with Sjögren's syndrome.

Methods: Three patients (six eyes) with Sjögren's syndrome who underwent bilateral LASIK were retrospectively evaluated for visual outcome, intraoperative and postoperative complications, dry eye status (subjective symptoms and objective findings, Schirmer test, vital staining of the ocular surface), and outcome satisfaction by subjective questionnaire. All patients had negative reflex tearing and were treated with topical autologous serum and/or punctal occlusion prior to LASIK to improve the ocular surface.
