Two-photon optical microscopy imaging of endothelial keratoplasty grafts

Graefe's Archive for Clinical and Experimental Ophthalmology, 2016
To investigate the microstructure of endothelial keratoplasty grafts using two-photon optical microscopy.Six endothelial keratoplasty grafts obtained from human donor corneoscleral tissues and prepared by submerged hydrodissection technique were imaged by two-photon optical microscopy.

Confocal Microscopy After Descemet Stripping Endothelial Keratoplasty: A Case Report

Cornea, 2009
To evaluate the clinical findings, visual outcomes, and confocal microscopic corneal features after Descemet stripping endothelial keratoplasty (DSEK) technique in Fuchs endothelial dystrophy.A 70-year-old female patient with pseudophakia and Fuchs endothelial dystrophy underwent small-incision DSEK surgery. Best spectacle-corrected visual acuity was 1.

Clinical Specular Microscopy

Archives of Ophthalmology, 1979
The clinical specular microscope shows the morphological appearance of the endothelium in normal and abnormal corneas. This instrument resolves the endothelial mosaic of the normal cornea into a quasiregular pattern of contiguous cells having well-defined cell boundaries.

Evaluation of Endothelial Function by In Vivo Microscopy

2007
This chapter describes a method that permits simultaneous measurement of leukocyte- endothelium interactions and endothelial nitric oxide (NO) levels in the microcirculation in vivo. The method is also useful to study the effect of NO replenishing therapy on adhesion of leukocytes to the vascular endothelium in acute and chronic inflammatory states of ...

A contact lens for endothelial and epithelial specular microscopy

American Intra-Ocular Implant Society Journal, 1983
A contact lens that facilitates specular microscopy of the corneal endothelium and epithelium with a standard slitlamp is described. It prevents blur from the superficial tear-film reflex, offers a wide field of specular illumination, and magnifies the field two times.

Imaging Mitochondria in Living Corneal Endothelial Cells Using Autofluorescence Microscopy

Photochemistry and Photobiology, 2007
AbstractWe report noninvasive autofluorescence mitochondrial imaging in cultured human corneal endothelial cells (HCECs). HCECs harvested from eye bank corneas were cultured in thin glass‐bottom plates. Mitochondria were imaged with an autofluorescence microscope using a DAPI filter set (excitation: G365, emission: band pass 445/50) and then, after ...

Atomic Force Microscopy Functional Imaging on Vascular Endothelial Cells

2012
One of the challenging tasks in molecular cell biology is to identify and localize specific binding sites on biological samples with high spatial accuracy (in order of several nm). During the past 5 years, simultaneous topography and recognition imaging (TREC) has become a powerful AFM-based technique for quick and easy high-resolution receptor mapping.

Correlative Microscopy and Tissue Culture of Congenital Hereditary Endothelial Dystrophy

American Journal of Ophthalmology, 1982
A 4 1/2-year-old boy with congenital hereditary endothelial dystrophy underwent successful bilateral penetrating keratoplasties. Visual acuity in both eyes was restored to 6/18 (20/60). Correlative microscopic analysis of the corneal button obtained from the first transplant showed an irregular epithelium, a continuously thickened Bowman's layer ...

[Is endothelial microscopy necessary before cataract surgery?].

Klinische Monatsblatter fur Augenheilkunde, 1991
Specular microscopy was performed before cataract surgery in approximately 3,500 patients. In 127 cases (approx. 4%), implantation of an intraocular lens (IOL) did not appear appropriate, in view of the condition of the cornea. Many of these patients had additional ocular pathology, such as retinal detachment, glaucoma, and intraocular inflammation. In

Endothelial Dysfunction in Hematological Patients: Sublingual Microscopy, Hyperspectral Imaging, and Serum Endothelial Markers

Blood
Background: EASIX measured before conditioning therapy is a validated marker to predict risk of sepsis and mortality after allogeneic stem cell transplantation (alloSCT) in the context of acute GVHD, and in a variety of malignant and non-malignant conditions outside alloSCT.
