BACKGROUND The radial artery is often used as the second arterial graft for coronary artery bypass grafting. Little is known about the differences in long-term patency between radial free and T grafts. This study was performed to determine long-term radial artery patency over a 15-year period. METHODS AND RESULTS Radial arteries were used as free grafts or T grafts for coronary artery bypass ...

pterygium is characterized by an elastic degeneration of the conjunctiva that extends across the limbos and invades the cornea. the recurrence rate is varied from 25-80% after primary closure to 6% with free conjunctival and iimbal grafts. several adjunctive therapies have been investigated for recurrent pte¬rygium. this article presents a 52-year-old athletic man who was seen for evaluation of...

BACKGROUND The purpose of this study was to evaluate the viability of skin grafts used for correction of cicatricial ectropion resulting from previous ablative surgery and radiotherapy for head and neck cancer and to report overall outcomes of cicatricial ectropion repair. METHODS This is a retrospective, noncomparative case series of all consecutive patients with head and neck cancer who had...

Subconjunctival gentamicin was identified as the cause of conjunctival chemosis and capillary closure in a recent study conducted in this department. The gentamicin preparation used in the study contained preservatives. The current prospective study was set up to investigate the role of preservatives in the conjunctival toxicity of subconjunctival gentamicin. Seventy five patients undergoing ca...

background: normal bacterial flora of the conjunctiva, which inhibits growth of opportunistic organisms, has an important role in the prevention of ocular infections. if resident flora is inhibited by disease or long-term application of antibiotics, opportunistic pathogens overgrow, leading to disease. objectives: the aim of this study was to investigate the effects of ophthalmic chloramphenico...

Background: Scleromalacia, in the form of scleral thinning, melting, and necrosis, is a potentially serious complication of pterygium excision. This study introduces a new biodegradable material, OlogenTM collagen matrix (OCM), to repair scleral thinning as an alternative to preserved scleral tissue, and evaluates the long-term outcomes of OCM for ocular surface reconstruction surgery. Case pre...

PURPOSE To describe the cases of conjunctival melanoma (CM) and report the disease-free interval (DFI) and overall survival (OS). METHODS The charts of 22 patients who were admitted to two hospitals between 1985 and 2006 were reviewed for pertinent data, including demographics, site of involvement in the conjunctiva and sub-sites, surgical treatment, and adjuvant treatment. RESULTS There we...
