MICROSCOPIC APPEARANCES OF CORNEAL GRAFTS

The immune privilege of corneal grafts.

Keratoplasty is the oldest and one of the most successful forms of solid tissue transplantation. In the United States, over 33,000 corneal transplants are performed each year. Unlike other forms of tissue transplantation, keratoplasties are routinely performed without the aid of tissue typing or systemic immunosuppressive drugs. In spite of this, 90% of the first-time corneal transplants will s...

Preservation of Corneal Grafts by Freezing.

predictors of endothelial cell density of corneal grafts after dsaek

purpose: to evaluate endothelial cell density (ecd) and morphology of clear corneal grafts after descemet stripping automated endothelial keratoplasty (dsaek) and to determine the factors that influence graft ecd postoperatively. methods: seventy-seven eyes (38 right eyes) of 64 patients (34 female subjects) who underwent dsaek for fuchs’ endothelial dystrophy (n=38) or pseudophakic bullous ker...

OPACIFICATION IN PERFORATING CORNEAL GRAFTS*t

As the success ofa grafting operation ultimately depends upon the transparency of the graft, the problem of opacification is of great interest and practical importance to the ophthalmic surgeon. This paper is the result of the study of some fifty personal cases in an attempt to elucidate certain aspects of the problem as it occurs in perforating corneal grafts. A graft may become opaque for one...

Donor cell survival in corneal grafts.

and connective tissue bands is strongly reduced. Imaging advantages in characterizing the pulleys have been attributed to secondary and tertiary gaze positions. Hence, ocular movement amplitudes larger than those investigated in our current publication are necessary to provide better insight. At present, spatial resolution of the published images generally is not high enough to separate horizon...
