Specular Microscopy of Iridocorneal Endothelia Syndrome
American Journal of Ophthalmology, 1980Clinical specular microscopic examination of 17 patients with features common to the iridocorneal endothelial syndrome (including Chandler's syndrome, iris nevus syndrome, and essential iris atrophy) showed pathognomonic endothelial changes and no areas of normal endothelial mosaic.

Ultrastructural Correlation of Specular Microscopy in Retinoblastoma
American Journal of Ophthalmology, 1986A patient with monocular retinoblastoma was examined with the wide-field specular microscope before undergoing enucleation. An unusual image on the corneal endothelium consisted of irregular oval dark structures within which bright reflections formed a lacy network.

Identification of Intraocular Tumors by Specular Microscopy
Cornea, 1985Five patients with confirmed diagnoses of intraocular tumors and anterior chamber extension were examined with a wide-field specular microscope. Uniquely shaped dark areas seen on the endothelial surface could be readily distinguished from inflammatory cells by their size and shape.

1990
A microscope applying the principles of specular reflection to the studies of corneal morphology was described about a quarter-century ago.1 This instrument was shown to be capable of photographing images reflected from the endothelial-aqueous interface, outlining endothelial cellular borders and some intracellular detail.

Clinical Specular Microscopy and Intraocular Surgery
Archives of Ophthalmology, 1979Seventy patients were studied prospectively, using the clinical specular microscope, to compare and evaluate the effects on the corneal endothelium of routine intracapsular cataract extraction (ICCE), ICCE with intraocular lens (IOL) implantation, phacoemulsification, and penetrating keratoplasty.

Video with Wide-Field SPecular Microscopy
Ophthalmology, 1981The addition of a high-sensitivity video camera and recording system has augmented and simplified the use of the wide-field specular microscope. In the noncontact mode, the tape is replayed and the clearest image frozen for analysis. When used as a contact instrument, video recording as the cornea is scanned allows examination of broad areas for ...

Corneal endothelium – Specular microscopy
Acta Ophthalmologica, 2022AbstractCorneal endothelium is a single layer of hexagonal cells covering the inner surface of the cornea and maintains the corneal deturgescence by continuous pumping of water and ions from the stroma to the aqueous humour. This mechanism is necessary to preserve the transparency of the cornea. The corneal endothelium is derived from the neural crest.

Specular Microscopy in Pars Plana Vitrectomy
Archives of Ophthalmology, 1983A prospective study of endothelial cell loss following pars plana vitrectomy and pars plana vitrectomy with lensectomy was performed in 21 eyes. Fifteen diabetic patients had either vitrectomy alone or vitrectomy with lensectomy. Six nondiabetic eyes were also included in this study. The average cell loss was between 2.3% and 3.9% in all cases.

Specular microscopy at Southampton Eye Hospital
Journal of Audiovisual Media in Medicine, 1990There is nothing significantly new in the technique of specular microscopy. The equipment has improved and the methods of cell counting have been automated using computer technology. This paper gives an account of how the old practice is still being used effectively in assessing the endothelial cell population, their shape and shape variability.
