| first rank symptoms | Those symptom's that, when present, indicate that the diagnosis of schizophrenia is likely, provided that organic or toxic aetiology is ruled out: delusion of control, thought broadcasting, thought withdrawal, thought insertion, hearing one's thoughts spoken aloud, auditory hallucinations that comment on one's behaviour, and auditory hallucinations in which two voices carry on a conversation. Synonym: first rank symptoms, schneiderian first rank symptoms. (05 Mar 2000) |

| absolute glaucoma | The final stage of blindness in glaucoma. (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) |
| acute glaucoma | <ophthalmology> 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. Symptom 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. (27 Sep 1997) |
| alpha-chymotrypsin-induced glaucoma | Transient secondary glaucoma following the use of alpha-chymotrypsin in cataract extraction. (05 Mar 2000) |
| 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) |
| aphakic glaucoma | Glaucoma following cataract removal. (05 Mar 2000) |
| capsular glaucoma | Glaucoma occurring in association with widespread deposition of cellular organelles on the lens capsule, ocular blood vessels, iris, and ciliary body. See: pseudoexfoliation of lens capsule. (05 Mar 2000) |
| malignant glaucoma | Secondary glaucoma caused by forward displacement of the iris and lens, obliterating the anterior chamber; usually follows a filtering operation for primary glaucoma. (05 Mar 2000) |
| ghost cell glaucoma | Glaucoma occurring after vitrectomy, arising from erythrocyte membranes blocking outflow channels of aqueous humor. (05 Mar 2000) |
| glaucoma | <ophthalmology> A group of eye diseases characterised by an increase in intraocular pressure which causes pathological changes in the optic disk and typical defects in the field of vision. It can be corrected by the use of laser light to punch a hole in the iris to relieve the intraocular pressure within the eye. The procedure is painless and requires no anaesthesia. (13 Nov 1997) |
| 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) |
| glaucoma detection | You may know of the air puff test or other tests used to measure eye pressure in an eye examination. But, this test alone cannot detect glaucoma. Glaucoma is found most often during an eye examination through dilated pupils after drops are put into the eyes during the exam to enlarge the pupils. This allows the eye care professional to see more of the inside of the eye to check for signs of glaucoma. (12 Dec 1998) |
| glaucoma fulminans | Acute angle-closure glaucoma rapidly followed by blindness. (05 Mar 2000) |
| glaucoma, neovascular | A form of secondary glaucoma which develops as a consequence of another ocular disease and is attributed to the forming of new vessels in the angle of the anterior chamber. (12 Dec 1998) |
