PURPOSE The aim of this study was to assess the antimicrobial effect of cryopreservation on donor globes with a previously positive culture. More specifically, our study aims at determining whether microbial organisms can still be cultured after cryopreservation in previously culture positive donor whole globes. METHODS This is a prospective quality assurance study of microbiological cultures...

PURPOSE Birdshot chorioretinopathy (BCR) is a bilateral, chronic uveitis primarily involving the posterior segment that often results in progressive vision loss. Histopathology on eyes with BCR has been limited, but we had the rare opportunity to study the eyes of a donor with BCR. We sought to compare immunolabeling in the eyes of this donor who was treated with immunosuppression for over 30 y...

THE prime indication for transplanting a graft of the patient's own corneal tissue from one side to the other is the presence of a dense extensive corneal scar on a potentially seeing eye, while the other side has a clear cornea in an eye with an intractable and blinding lesion in the intra-ocular media or fundus. Such cases are not commonly seen, but have been reported mainly because the best ...

PURPOSE Most people see, around bright lights against dark backgrounds, a radiating pattern of numerous fine, slightly colored needles of light-the so called ciliary corona. The purpose of this study was to try to explain this phenomenon. METHODS Recently, it has been shown that light-scattering in the eye, measured psychophysically and on human donor lenses, can be explained assuming the pre...

Abstract Semitransparent organic solar cells (ST‐OSCs) have attracted increasing attention due to their promising prospect in building‐integrated photovoltaics. Generally, efficient ST‐OSCs with good average visible transmittance (AVT) can be realized by developing active layer materials light absorption far from the range. Herein, development of ultrawide bandgap polymer donors near‐ultraviole...

A STAND, developed at this hospital, for holding the donor eye while a corneal graft is trephined and dissected is particularly useful for lamellar, annular, or segmental grafts, especially where direct sutures are used (Fig. 1). Essentially this is a modified Tudor-Thomas stand, so designed as to rotate on a plinth carrying a spring-loaded metal ball (Fig. 2A), which engages consecutively into...

Why do things sometimes go wrong? Some of the causes are: • Inadequate communication between the donor of the equipment and the receiving eye unit, so that the eye unit ends up with an item which is not appropriate, is not robust, cannot be maintained, does not include spare parts or a manual, and which no-one knows how to use. • Failure to identify all the costs involved, such as training, shi...

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...

purpose: to describe a novel surgical technique for in vivo limbal stem cell cultivation for reconstruction of corneal epithelium in total limbal stem cell deficiency (lscd). methods: patients suffering from chronic total unilateral lscd due to a chemical injury were sequentially included. one small limbal block (2x1 mm) harvested from contralateral healthy eye sutured over the amniotic membran...
