The conjunctivas of 273 inflamed eyes were cultured by both aerobic and anaerobic techniques. Isolations were obtained from 267 (97.8%) of the eyes. Aerobic organisms were isolated from 237 (86.8%) of the conjunctivas. Staphylococcus aureus from 63 (23.1%) of the diseased eyes was the aerobic pathogen most often isolated. Anaerobic bacteria were isolated from 172 (63.0%) of the conjunctivas. Pr...

PURPOSE To evaluate mitogen-activated protein kinases (MAPKs) and nuclear factor-κB (NF-κB) signaling pathways in pterygium and pterygium-free conjunctivas. METHODS Primary pterygia (n = 21), ipsilateral superior-temporal bulbar conjunctivas (n = 8), and healthy conjunctival (n = 5) biopsy specimens were analyzed. Total and phosphorylated (phospho) levels of extracellular-regulated 1/2 (ERK1/...

OBJECTIVES To investigate the characteristics and effects of allogenic conjunctiva and conjunctival extracellular matrix (ECM) as the substitute of conjunctival tissues. BACKGROUND The symptoms of the frequently-occurring conjunctival injury not only make people ugly, but also lead to blindness, which seriously endanger the quality of life of the patients. METHODS The bulbar conjunctivas of...

Changes in the microbial populations in the conjunctival sacs of animals have traditionally been evaluated using conventional microbiology techniques. The goal of this study was to examine the suitability of a methodology which may reveal a previously unknown microbiome inhabiting feline conjunctival membranes. In the present study, we determined the microbial diversity in feline conjunctivas b...

PURPOSE The severity of allergic conjunctivitis (AC) correlates with the degree of eosinophil infiltration into the conjunctiva, which is believed to be mediated by chemokines and adhesion molecules. The adhesion molecule very late antigen (VLA)-4 and its ligand, vascular cell adhesion molecule (VCAM)-1, are known to play important roles in eosinophil infiltration. However, the expression and f...

PURPOSE To investigate antigen (Ag) specificity, activation, and effector function of the Ag-specific T cells involved in the development of experimental immune-mediated blepharoconjunctivitis (EC), an experimental conjunctivitis. METHODS EC was induced in Brown Norway rats by injection of ovalbumin (OVA)-specific T cells followed by OVA challenge with eye drops. Eyes, including the conjuncti...

chloroma or granulocytic sarcoma (gs) is a malignant neoplasm of myeloid lineage that occur in a variety of anatomic sites other than the bone marrow including soft tissue, bone, lymph node, nasal fossa, skin and sometime in the orbit. in the subconjunctiva it is rarely reported. a 4-year-old girl with a history of treated acute myelogenous leukemia was referred to farabi eye hospital, tehran, ...

In 11 patients with active corneal xerophthalmia, conjunctival biopsies were obtained at various intervals after massive-dose systemic vitamin A therapy. Goblet cells began to repopulate the inferonasal quadrant of the conjunctivas after two weeks, and they reached normal concentrations after one month. Corneal healing proceeded much more rapidly than that, suggesting that a full complement of ...
