BACKGROUND Conjunctival mucosa-associated lymphoid tissue (MALT) lymphoma is a rare, low-grade, non-Hodgkin's B-cell lymphoma. Herein, we report our successful management of the large conjunctival defect caused by resection of conjunctival MALT lymphoma by covering it with transplanted amniotic membrane. CASE A 28-year-old Japanese man, who had been diagnosed histologically as having conjunct...

BACKGROUND Differential expression of chemokine genes were investigated in various types of ocular surface cells. METHODS Primary cultures of human corneal epithelial cells (n = 3), corneal fibroblasts (n = 2), conjunctival epithelial cells (n = 2) and conjunctival fibroblasts (n = 2) were established and incubated with or without interleukin (IL)-4 (30ng/ml) and tumor necrosis factor (TNF)-a...

PURPOSE To elucidate the status of the conjunctival inflammation in atopic keratoconjunctivitis (AKC) using laser scanning confocal microscopy and compare the relevant findings with conjunctival brush cytology in a prospective controlled study. METHODS Twenty eyes from 20 AKC patients as well as 16 eyes from 16 age and sex matched normal subjects were studied. The subjects underwent tear film...

INTRODUCTION The purpose of this study was to examine and compare the conjunctival irritation (congestion, swelling, and discharge) of topical bimatoprost ophthalmic solution 0.01% and bimatoprost ophthalmic solution 0.03% in rabbits. METHODS Six healthy New Zealand White rabbits were treated with either bimatoprost 0.01% or bimatoprost 0.03% (3 animals/group). One dose (2 drops/dose) of stud...

PURPOSE To determine whether human conjunctival epithelium expresses any of the human mucin genes designated MUC2 through MUC7. METHOD Northern blot analysis was performed using total RNA isolated from surgically removed conjunctival tissues. Complementary DNA or oligonucleotides to the tandem repeat region of each mucin gene were labeled and hybridized to conjunctival RNA. In situ hybridizat...

The authors examined immunofluorescently the specific cytokeratin staining patterns of corneal, limbal, and conjunctival epithelium with PKK-1, 8.12, 4.62, and 8.60 monoclonal anticytokeratin antibodies. Observations were made on unfixed frozen postmortem human tissue. The PKK-1 antibody stain was observed in all layers of corneal epithelium but only in suprabasal layers of limbal and conjuncti...

PURPOSE The ocular surface is covered by two biologically distinct epithelia: corneal and conjunctival. The expression of keratin12 (K12) is currently considered a hallmark of cornea-type differentiation. In the current study, the biological features of K12-positive cells in human bulbar conjunctival epithelium were examined. METHODS Human conjunctival tissues were subjected to investigate th...

PURPOSE To report the establishment of a human conjunctival epithelial cell line lacking the functional tumor-associated calcium signal transducer 2 (TACSTD2) gene to be used as an in vitro model of gelatinous drop-like corneal dystrophy (GDLD), a rare disease in which the corneal epithelial barrier function is significantly compromized by the loss of function mutation of the TACSTD2 gene. ME...

PURPOSE To compare the levels of conjunctival transforming growth factor beta (TGF-β) between glaucoma and control patients and to determine conjunctival TGF-β levels before and 3 months after augmented primary trabeculectomy. METHODS Patients with primary open angle glaucoma (POAG) or primary angle closure glaucoma (PACG) admitted for mitomycin (MMC) augmented primary trabeculectomy due to f...

PURPOSE Conjunctival melanoma is a rare but potentially deadly tumor of the eye. Despite effective local therapies, recurrence and metastasis remain frequent. Once the tumor has metastasized, treatment options are limited and the prognosis is poor. To date, little is known of the genetic alterations in conjunctival melanomas. EXPERIMENTAL DESIGN We conducted genetic analysis of 78 conjunctiva...
