Modern corneal transplantation is internationally accepted as highly successful and cost effective. The avascularity of the cornea puts it in a relatively immune-privileged position, and complications due to graft rejection can be handled more effectively than in other solid organs. Modern microsurgery, which has the ability to manage postoperative astigmatism, has turned corneal transplant sur...

purpose: to determine bacterial contamination of corneas and corneal storage media provided from the eye bank of i.r. iran to rasool akram medical center. methods: this descriptive study was performed on 70 corneoscleral rims and corneal storage media. one milliliter of corneal storage media and the corneoscleral rim were sent to microbiology laboratory at the time of penetrating keratoplasty a...

A retrospective study was made of the effectiveness of an eye bank decontamination and storage method. A comparison was made between microbial cultures taken from the limbus at enucleation and from scleral remnants recovered after surgery. Organisms were isolated from the limbus of 73% of donor eyes and from 4% of remnants. Standard eye bank procedures were found to eradicate gut and skin organ...

AIMS To examine the frequency of intraocular metastases in patients who had died of cancer, in an eye bank and necropsy population sample. METHODS The first group included 302 cancer cases received from the Wisconsin Eye Bank between 1988 and 1993. In the second group, ocular pathology records at the Wilmer Institute from 1976 to 1980 were analysed for ocular metastases in necropsy subjects d...

PURPOSE To evaluate the effect of donor and eye bank characteristics on graft rating and clinical outcomes after penetrating keratoplasty (PK) for keratoconus. METHODS This retrospective interventional case series included 252 keratoconic eyes which underwent PK. Donor data included age and sex, cause of death, death-to-preservation time, preservation-to-surgery time, epithelial and stromal s...

Part 1271.85 a (5) Syphilis testing should not be required for eye tissue. Dr. Marian Macsai et al documented that syphilis is not transmitted from donor to recipient by cornea1 transplant. Dr. Jay Pepose documented the ineffectiveness of using syphilis testing as a marker for other diseases. Additionally, unnecessary syphilis screening would result in a 7.5% increase in the cost of serology te...

To the Editor: Researchers who wish to study human eye material sometimes experience severe difficulties in finding a source of tissue for their laboratory investigations. The recent formation of tissue procurement committees by the Retinitis Pigmentosa Foundation and the National Diabetes Research Interchange attests to the fact that those with special tissue requirements are preparing to meet...

PURPOSE To describe the histopathologic findings of an eye bank specimen containing an optic nerve pit with associated serous elevation of the macula and cavernous atrophy of the optic nerve. METHODS An eye bank specimen found to have an optic nerve pit with serous elevation of the macula was grossly examined and photographed. The globe was processed for both light and scanning electron micro...

The eyes of a 25-year-old male were collected by the Utah Lions Eye Bank after his suicide by hanging. Following dissection of the corneoscleral buttons from intact globes, bilateral detached Descemet's membranes with subsequent scrolling in the periphery were observed. We believe these findings were caused by a large increase in intraocular pressure secondary to the hanging. Lens and anterior ...
