[Computerized perimetry in infants treated with ethambutol (author's transl)]. 1982

E Gramer, and R Jeschke, and G K Krieglstein

Computerized perimetry of the central visual field (Competer) was utilized in 12 eyes of children treated with Ethambutol because of tuberculosis to verify potential visual hazards of the drug. Visual acuity, visual field and the mean retinal threshold of the central field revealed no significant changes with increasing cumulative Ethambutol dose up to 166.5 g. The visual field was re-checked five times with a consecutive time lapse of 7 weeks. It can be concluded that the critical total dose of 150 g that is considered to be potential dangerous in adults does not affect the optic nerve of the infant either. Since this total dose can be exceeded in the continued treatment of the disease parents should be aware of the necessity of repeated visual field examinations or color vision testing. This concern is especially valid in infants suffering from renal tuberculosis because of higher plasma levels of the drug when excretion is prolonged.

D004977 Ethambutol An antitubercular agent that inhibits the transfer of mycolic acids into the cell wall of the tubercle bacillus. It may also inhibit the synthesis of spermidine in mycobacteria. The action is usually bactericidal, and the drug can penetrate human cell membranes to exert its lethal effect.

D014792 Visual Acuity Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast. Acuities, Visual,Acuity, Visual,Visual Acuities
