Amyloid degeneration, in which waxy-looking masses grow from the palpebral conjunctiva of both lids, often attaining very considerable dimensions.
No dressings should be applied over the open palpebral aperture.
The object of this operation is to shorten the eyelid by removing the upper portion of the tarsal plate, the cut margin of which is subsequently sutured to the tendon of the levator palpebræ and the palpebral ligament.
Tarsal plates, which are attached to the orbital margins by the palpebral ligaments and which thereby form a barrier to the passage of infection backwards into the orbit.
In contraction of the palpebral aperture, either due to a congenital condition, or the result of a wound, trachoma, or other cicatricial contraction.
This procedure is especially suitable for cases in which the base of the socket opposite the palpebral aperture has to be enlarged, and it is usually performed prior to Maxwell’s operation for the restoration of the fornices in severe cases.

The palpebral fissure is smaller than its fellow, and the eyeball sinks into the orbit.
Its palpebral aperture is much narrower than in the ordinary eye, and instead of having the form of an almond, it has rather that of a scalene triangle (Figs.
This disposition is due to the too high attachment of the external palpebral ligament to the skull, as Regalia has shown.
Sometimes this puffiness only extends to the outer part of the eyelid; we have thus a variety of the Mongolian eye, with a palpebral triangular opening, very frequent among the eastern Finns (Fig.

Not only are the eyes unusually tall, but the palpebral lobe is much reduced, so that many of the lenses look upward and inward, as well as outward, forward and backward.
This condition is generally associated with similar contractions in other facial muscles, as in a case of facial and palpebral tic with platysma involvement recorded by Meirowitz,[62] or as in young M.
Palpebral tics are among those that ordinarily begin by a spasmodic reaction to an extraneous source of irritation, such as that yielded by a foreign body, a speck of dust, an eyelash, or by any form of conjunctival inflammation.

They may at first have been an involuntary motor response to nipping of palpebral twigs of the trigeminal, but at a later period their independence was constant and pronounced.
It may be difficult to decide whether this is the result of mechanical compression of the lachrymal gland or an exaggerated secretion of tears under the influence of stimulation of the lachrymo-palpebral twig of the orbital nerve.
An unvarying post-traumatic palpebral tic in an hysterical subject cannot be said to constitute the syndrome of Gilles de la Tourette, in spite of the coprolalia.
The terms blepharospasm and blepharoclonus, sometimes applied to tonic and to clonic involuntary palpebral contractions respectively, ought to be strictly reserved for spasms and contractures properly so called.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "palpebral" in a variety of sentences. We hope that you will now be able to make sentences using this word.
