[The corneal reflex stimulated pneumatically (author's transl)]. 1976

C F Seiler

We describe an apparatus measuring the cornealreflex stimulated pneumatically. The flow of preassurised air in the range of 0.1-1.5 bar is controlled by an electromagnetic switch. The time the valve is open, is variable. The air flow is directed to the cornea of the eye. The blink reflex is recorded by means of the surface electromyogramm and displayed on the screen of a storage scope. The device allows a clean, reproducable and simple measurement of the cornealreflex.

D012018	Reflex	An involuntary movement or exercise of function in a part, excited in response to a stimulus applied to the periphery and transmitted to the brain or spinal cord.
D003315	Cornea	The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.
