| lethal midline granuloma | Destruction of the nasal septum, hard palate, lateral nasal walls, paranasal sinuses, skin of the face, orbit and nasopharynx by an inflammatory infiltrate with atypical lymphocytic and histiocytic cells; presumably a form of lymphoma in most cases. An obsolete term for polymorphic reticulosis. Synonym: granuloma gangrenescens, malignant granuloma, midline malignant reticulosis granuloma. (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) |
| glaucoma, angle-closure | A form of glaucoma in which the intraocular pressure increases because the angle of the anterior chamber is blocked and the aqueous humor cannot drain from the anterior chamber. (12 Dec 1998) |
| perceptual closure | The tendency to perceive an incomplete pattern or object as complete or whole. This includes the gestalt law of closure. (12 Dec 1998) |
| closure | 1. The completion of a reflex pathway. 2. The place of coupling between stimuli in the establishment of conditioned learning. 3. To achieve or experience a sense of completion in a mental task. (05 Mar 2000) |
| closure principle | In psychology, the principle that when one views fragmentary stimuli forming a nearly complete figure (e.g., an incomplete rectangle) one tends to ignore the missing parts and perceive the figure as whole. See: gestalt. (05 Mar 2000) |
| complex closure | <surgery, technique> A sutural repair that may involve multi-layered closure, debridement or advanced tissue repair (plasty). (05 Jan 1998) |
| health facility closure | The closing of any health facility, e.g., health centres, residential facilities, and hospitals. (12 Dec 1998) |
| simple closure | A single layer closure. (27 Sep 1997) |
