| pupillary block glaucoma | Glaucoma secondary to failure of the aqueous humor to pass through the pupil to the anterior chamber. (05 Mar 2000) |
|---|---|
| hypersecretion glaucoma | Glaucoma caused by excessive formation of the aqueous humor. (05 Mar 2000) |
| simple glaucoma | <ophthalmology> A disorder which is characterised by increased pressure within the eyeball. This occurs secondary to the chronic blockage of normal fluid circulation within the eye. Increased pressure within the eye can cause damage to the optic nerve and eventual blindness. Glaucoma is the leading cause of blindness. Symptoms include decreased vision, halos around lights (worse at night) and mild chronic headaches. Treatment is generally with beta-blocker eyedrops. Synonym: chronic glaucoma, compensated glaucoma, simple glaucoma, glaucoma simplex. (22 Sep 2002) |
| narrow-angle glaucoma | angle-closure glaucoma |
| neovascular glaucoma | Glaucoma occurring in rubeosis iridis. (05 Mar 2000) |
| Donders' glaucoma | An obsolete eponym for open-angle glaucoma. (05 Mar 2000) |
| open-angle glaucoma | <ophthalmology> A disorder which is characterised by increased pressure within the eyeball. This occurs secondary to the chronic blockage of normal fluid circulation within the eye. Increased pressure within the eye can cause damage to the optic nerve and eventual blindness. Glaucoma is the leading cause of blindness. Symptoms include decreased vision, halos around lights (worse at night) and mild chronic headaches. Treatment is generally with beta-blocker eyedrops. Synonym: chronic glaucoma, compensated glaucoma, simple glaucoma, glaucoma simplex. (22 Sep 2002) |
| eyes, glaucoma | Disease (there is more than one type) characterised by increased pressure within the eye. Glaucoma can lead to blindness. Glaucoma is five times more likely to occur in Blacks than in Whites. Early detection of glaucoma is essential to the preservation of vision. Glaucoma can be treated with medications, laser or traditional surgery. (12 Dec 1998) |
| low tension glaucoma | Optic nerve atrophy and excavation with typical field defects of glaucoma but without abnormal increase in intraocular pressure. (05 Mar 2000) |
| cancer, malignant melanoma | A skin cancer that begins in cells called melanocytes that can grow together to form benign (not cancerous) moles. A change in size, shape, or colour of a mole can be a sign of melanoma. Melanoma can be cured if detected early, before spread (metastasis) to other areas of the body. Diagnosis is confirmed with a biopsy of the abnormal skin. Sun exposure can cause skin damage that can lead to melanoma. (12 Dec 1998) |
| canine malignant lymphoma | <tumour> A progressive fatal disease of dogs characterised by neoplastic transformation and proliferation of lymphoid cells, usually originating in solid lymphoid organs (lymphosarcoma) or bone marrow (lymphocytic leukaemia). (05 Mar 2000) |
| malignant | <oncology> Tending to become progressively worse and to result in death. Having the properties of anaplasia, invasion and metastasis, said of tumours. Origin: L. Malignans = acting maliciously (18 Nov 1997) |
| malignant anaemia | <haematology> A form of anaemia (low red blood cell counts) that results when the bone marrow fails to produce adequate numbers of red blood cells due to a deficiency in vitamin B12. Intrinsic factor, necessary for normal B12 absorption, may be the underlying cause for B12 deficiency if is not produced in the gastric glands (in the stomach). Origin: Gr. Haima = blood (27 Sep 1997) |
| malignant carcinoid syndrome | <syndrome> A symptom complex associated with carcinoid tumour and characterised by attacks of severe flushing of the skin, diarrhoeal watery stools, bronchoconstriction, sudden drops in blood pressure, oedema, and ascites. The carcinoid tumours are usually located in the gastrointestinal tract and metastasize to the liver. Symptoms are caused by tumour secretion of serotonin, prostaglandins, and other biologically active substances. Cardiac manifestations constitute carcinoid heart disease. (12 Dec 1998) |
| malignant catarrh | A herpes virus infection of cattle characterised by catarrhal inflammation of the upper respiratory and alimentary epithelia, keratoconjunctivitis, encephalitis and lymph node enlargement. Syn: bovine epitheliosis, snotsiekte. (12 Dec 1998) |
