Synonym: Galassi's pupillary phenomenon, Gifford's reflex, lid-closure reaction, orbicularis phenomenon, orbicularis pupillary reflex, Piltz sign, Westphal's pupillary reflex, Westphal-Piltz phenomenon.

| Collier's tucked lid sign | <clinical sign> Unilateral or bilateral lid retraction due to midbrain lesion; occurring at any age. See: setting sun sign, Epstein's sign. Synonym: Collier's tucked lid sign. (05 Mar 2000) |
| nose-bridge-lid reflex | Contraction of the orbicularis oculi muscles upon tapping the margin of the orbit, or the bridge or tip of the nose. Synonym: nose-bridge-lid reflex, nose-eye reflex. (05 Mar 2000) |
| upper lid | The superior, larger and more mobile of the two eyelids which covers most of the anterior surface of the eyeball, including the cornea, when closed; a portion of the lacrimal gland and the aponeurosis of the levator palpebrae superioris muscle extend into it, the muscle opening the closed eye and providing additional elevation when the gaze is directed upward. Synonym: palpebra superior, upper lid. (05 Mar 2000) |
| lid | 1. That which covers the opening of a vessel or box, etc.; a movable cover; as, the lid of a chest or trunk. 2. The cover of the eye; an eyelid. "Tears, big tears, gushed from the rough soldier's lid." (Byron) 3. <botany> The cover of the spore cases of mosses. A calyx which separates from the flower, and falls off in a single piece, as in the Australian Eucalypti. The top of an ovary which opens transversely, as in the fruit of the purslane and the tree which yields Brazil nuts. Origin: AS. Hlid, fr. Hlidan (in comp) to cover, shut; akin to OS. Hlidan (in comp), D. Lid, OHG. Hlit, G. Augenlid eyelid, Icel. Hli gate, gateway. Source: Websters Dictionary (01 Mar 1998) |
| lid crutch spectacles | Spectacles with little offsets of metal with smooth edges which engage above the upper eyelid and keep it raised above the pupil in cases of paralytic blepharoptosis. Synonym: Masselon's spectacles. (05 Mar 2000) |
| lid reflex | A contraction of the eyelids when the cornea is lightly touched with a camel-hair pencil. Synonym: lid reflex. Reflection of light from the surface of the cornea. (05 Mar 2000) |
| lower lid | The inferior, smaller and less mobile of the two eyelids; a check ligament from the inferior rectus muscle extends into it, pulling the lid inferiorly when the gaze is directed downward. Synonym: palpebra inferior, lower lid. (05 Mar 2000) |
| acute angle closure glaucoma | <ophthalmology> An increase in pressure within the anterior chamber of the eye. There are two forms of glaucoma: acute angle closure and open angle glaucoma. (27 Sep 1997) |
| angle closure glaucoma | <ophthalmology> Primary glaucoma in which contact of the iris with the peripheral cornea excludes aqueous humor from the trabecular drainage meshwork causing a sudden blockage of the normal fluid circulation within the eyeball resulting in increased intraocular pressure. Increased pressure within the eyeball can cause damage to the optic nerve and blindness. Symptoms include severe eye or facial pain, nausea, vomiting, decreased vision, blurred vision and seeing halos around objects. The eye appears red with a steamy cornea and a fixed (nonreactive) dilated pupil. Treatment is emergent with medications to lower the pressure within the eye. Synonym: acute glaucoma, closed-angle glaucoma, narrow-angle glaucoma. (14 Aug 2000) |
| anodal closure contraction | An obsolete term for the momentary contraction of a muscle under the influence of the positive pole when the electrical circuit is established. (05 Mar 2000) |
| anodal closure tetanus | An obsolete term for a tetanic muscular contraction occurring during the time the circuit is closed, the current then running, while the positive pole is applied. (05 Mar 2000) |
| velopharyngeal closure | The apposition of the palate to the upper posterior pharyngeal wall as in deglutition and in some speech sounds. (05 Mar 2000) |
| cathodal closure contraction | An obsolete term for the momentary contraction of a muscle under the influence of the negative pole when an electrical circuit is established. (05 Mar 2000) |
| cathodal closure tetanus | An obsolete term for a tetanic muscular contraction occurring during the time the circuit is closed, the current then running, while the negative pole is applied. (05 Mar 2000) |
