| compensated 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) |

| compensated metabolic alkalosis | The retention of acid, primarily carbon dioxide by the lung and acid ions by the renal tubules, to reduce the effect on the pH of the blood of excess alkali produced by ingestion or metabolism of alkali-producing substances. (05 Mar 2000) |
| compensated respiratory acidosis | Retention of bicarbonate by the renal tubules to minimise the effect on the pH of the blood of retention of carbon dioxide by the lungs, such as occurs with hypoventilation. (05 Mar 2000) |
| compensated respiratory alkalosis | The increased excretion of acid ions by the kidney to minimise the effect on the pH of the blood of excessive loss of carbon dioxide via the lungs, such as occurs with hyperventilation. (05 Mar 2000) |
| compensating curve | The anteroposterior and lateral curvature in the alignment of the occluding surfaces and incisal edges of artificial teeth; used to develop balanced occlusion. (05 Mar 2000) |
| compensating emphysema | Compensatory emphysema, increase in the air capacity of a portion of the lung when another portion is consolidated, shrunken, or unable to perform its respiratory function; the alveoli are distended, but there is no destruction of alveolar walls, and hence, no true emphysema, as this term is now defined. (05 Mar 2000) |
| compensating eyepieces | <microscopy> Those designed for use with objectives such as apochromats in order to correct chromatic aberration. (05 Aug 1998) |
| compensating ocular | An ocular that compensates and corrects for the effects of chromatic aberration in the objective. (05 Mar 2000) |
| compensation | In interference microscopy, compensation for the phase difference introduced by the object, measured by introducing a quarter wavelength plate and rotating the analyser: the angle of rotation is proportional to the optical path difference. (18 Nov 1997) |
| compensation neurosis | The development of symptoms of neurosis believed to be motivated by the desire for, and hope of, monetary or interpersonal gain. (05 Mar 2000) |
| compensatory | Providing compensation; making up for a deficiency or loss. (05 Mar 2000) |
| compensatory atrophy | Atrophy especially of an endocrine organ as a result of its function being assumed by a new source of hormone. (05 Mar 2000) |
| compensatory circulation | Circulation established in dilated collateral vessels when the main vessel of the part is obstructed. (05 Mar 2000) |
| compensatory hypertrophy | Increase in size of an organ or part of an organ or tissue, when called upon to do additional work or perform the work of destroyed tissue or of a paired organ. (05 Mar 2000) |
| compensatory hypertrophy of the heart | Thickening of the walls of the heart in response to vascular, valvular, other heart disease, or athletic conditioning. (05 Mar 2000) |
