  • Title: Role of computer-assisted analysis of the corneal endothelium in vitreoretinal surgery with intraocular silicone oil injection: a technical report.

    Abstract:
    The innermost lining of the cornea consists of a single layer of cells called the endothelium. Despite its name, the endothelium of the cornea differs considerably from the vascular endothelium, both functionally and morphologically. The corneal endothelium plays a fundamental role in maintaining the transparency of the corneal membrane, as the result of both its function as a barrier against penetration of the aqueous humor in the parenchyma and its ability to remove water from the stroma (usually referred to as the endothelial "pump" function). Any abnormality in the corneal endothelium causes, first, the impairment of its function as a barrier and pump due to the loss of stromal anti-turgor mechanisms, followed by edema and possible development into keratopathy. The specular microscope is an instrument which makes it possible to see the endothelial "mosaic" in the reflected image of the posterior corneal surface. A large variety of clinical specular microscopes is presently available, both contact and non-contact, which allow, for easy and rapid photography of the corneal endothelium "in vivo". In the present case, we used a non-contact computerized specular microscope to analyze the corneal endothelium in a group of patients affected by retinal detachment who needed to undergo vitreoretinal surgery with immission of silicone oil into the vitreal chamber.
