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 of Corneal Epithelium
Archives of Ophthalmology, 1983Specular microscopy was used to study the morphologic appearance of normal and regenerating rabbit corneal epithelium before and after corneal abrasion or heptanol application. Specular photomicrographs of the denuded area and healing epithelium were taken for two to three weeks as the epithelium regenerated, as well as prior to trauma.

Specular Microscopy of Epithelial Downgrowth
Archives of Ophthalmology, 1978Specular microscopy in a case of pathologically proved epithelial downgrowth demonstrated a characteristic pattern of cell borders in the area of the epithelial downgrowth. This noninvasive clinical test may prove to be helpful in the early diagnosis of epithelial ingrowth following various intraocular surgical procedures.

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.

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.

Specular microscopy with intraocular lens implantations
American Intra-Ocular Implant Society Journal, 1981Specular microscopy performed six months postoperatively on 122 lens implant patients showed that endothelial cell loss rates varied according to method of cataract extraction and type of lens implant. Phacoemulsification with implantation of a Platina-style lens was associated with the highest cell loss; planned extracapsular cataract extraction with ...

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.

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.

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 ...
