BACKGROUND The aim of this study was to determine prolidase activity in conjunctival tissue and its relationship with pterygium. MATERIAL AND METHODS Prolidase activity was measured in 23 pterygium and 25 healthy conjunctival tissues and the 2 groups were compared. RESULTS Prolidase enzyme activity could not be measured in either the healthy conjunctival or in pterygium tissues. The mean se...

DNA from human papillomavirus (HPV) type 16 has been recently identified in conjunctival epithelial dysplasia and carcinoma. In other body sites, HPV 16 is thought to play a role in the development of dysplastic lesions. To further explore the relationship between HPV and conjunctival neoplasia, we examined paraffin-embedded tissue samples from 42 biopsies or excisions from 38 patients whose le...

purpose: to evaluate and compare the results of different surgical methods for post-trabeculectomy bleb revision at labbafinejad medical center, tehran-iran, from 1999 to 2003. methods: this study was conducted on all patients who underwent post-trabeculectomy bleb revision due to hypotony [intraocular pressure (iop) less than 6 mmhg] or bleb leakage. surgical methods were: conjunctival advance...

PURPOSE The aim of this study was to evaluate the effect of gefarnate on mucin-like glycoprotein secretion in isolated rabbit conjunctival tissue, and on corneal epithelial damage in rabbit and cat dry-eye models. METHODS Conjunctival tissue isolated from rabbits was treated with gefarnate. Mucin-like glycoprotein was detected in the culture supernatant by an enzyme-linked lectin assay. Gefar...

BACKGROUND Glaucoma surgery is the most effective means for lowering intraocular pressure by providing a new route for fluid to exit the eye. This new pathway is through the sclera of the eye into sub-conjunctival tissue, where a fluid filled bleb typically forms under the conjunctiva. The long-term success of the procedure relies on the capacity of the sub-conjunctival tissue to absorb the exc...

Objectives- Using conjunctival graft to replace experimental mucosal defects of teatsinus.Study- Experimental study.Animals- Five healthy, mature, lactating, Jersey cows.Methods- Conjunct ival mucosal gra fts with teat cannula were evaluated in the repair of experimentalteat sinusmucosal lesions. A 1.5xl em wide circumferential strip of mucosa was resected from each teat in five Jersey cows. Ea...

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...

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...

PURPOSE To evaluate DNA content and cellular proliferation rates in primary and recurrent pterygia. METHODS Matched pterygium and superior conjunctiva tissue were obtained in 36 eyes of 36 patients undergoing pterygium excision with conjunctival autografting (24 primary pterygia, 12 recurrent pterygia). Epithelial and fibrovascular layers were separated for analysis. Matched superior conjunct...
