We successfully used autogenous periosteum to reinforce the weakened sclera of two patients with necrotizing scleritis. One of these patients previously had an onlay scleral graft made from homologous banked sclera, which had subsequently melted. Autogenous periosteum is suggested as an alternative to banked sclera for scleral reinforcement.
At three university centres 66 patients presenting with herpetic dendritic or geographic ulcers participated in a double-blind comparative study of 3% acyclovir and 3% vidarabine ointment. There was healing in 31 (97%) of the 32 patients treated with acyclovir, in a mean time of 6.3 days, and in 30 (88%) of the 34 treated with vidarabine, in a mean time of… (More)
We studied the effect of altering the pH of an artificial tear preparation on the tolerance of 20 patients with keratoconjunctivitis sicca. Of those who expressed a preference, 11/17 preferred a tear substitute more alkaline than any preparation now available in North America. We recommend an alkaline tear substitute as a valuable alternative in patients… (More)
The endothelial function of rabbit corneas stored in modified tissue culture medium (McCarey-Kaufman medium) for periods of 4, 8, or 12 days was studied after penetrating keratoplasty using the specular microscope and the response to temperature reversal. Our results indicate that rabbit donor corneas stored in McCarey-Kaufman (M-K) medium are suitable for… (More)
Dextran, with a minimal molecular weight of 40,000, can pass in and out of the corneal endothelium during storage in M-K medium. Results suggest that the degree of penetration of dextran depends on the length of storage and the condition of the endothelium.
We present our evaluation of the McCarey-Kaufman (M-K) method of corneal storage. Sixty-six rabbit corneas were stored in the M-K medium at 4 C for periods of four, eight, and 12 days. Endothelial viability was assessed, using the specular microscope, the phenomenon of temperature reversal, and known inhibitors of endothelial cell function. Our results… (More)
The slow-release artificial tear (SRAT) is a biodegradable, cellulosic polymer without preservative which is inserted beneath the tarsus of the lower lid, and which provides continuous lubrication and tear film stability to the eye. The SR-AT has been shown to reduce both subjective symptoms and objective signs in patients with keratitis sicca, and is a… (More)
The endothelial viability of rabbit corneas subjected to various forms of cadaveric and moist chamber storage was evaluated by means of the specular microscope and the rate of stromal deturgescence during a temperature reversal response. Delays in the postmortem enucleation and refrigeration of potential donor corneas was shown to be detrimental to the… (More)
PURPOSE To determine whether a bandage soft contact lens (BSCL) is routinely needed in the postoperative laser in situ keratomileusis (LASIK) patient and whether topical tetracaine 0.5% or diclofenac sodium 0.1% (Voltaren) is more effective in relieving patient discomfort than a BSCL. SETTING LCA-Vision Center, Toronto, Ontario, Canada. METHODS In this… (More)
Many patients with keratitis sicca complain that the commercially available artificial tears burn when they are instilled and fail to relieve their distressing symptoms. We examined the effects of altering both the pH and osmolarity of hydroxypropyl methylcellulose tear substitute on the tolerance of 15 patients with varying degrees of keratitis sicca.… (More)
