Evaluation of electronic tonometers in the rabbit eye.

摘要: The MacKay-Marg, pneumatonograph, and EMT-20 tonometers were evaluated in the normal rabbit eye. Tonometric scale readings compared with manometric recordings from anterior chamber. Tonometry was performed system closed open to reservoir column. MacKay-Marg tonometer systems highly reliable (goodness of fit (r2) = 0.958 0.961, respectively) intraocular pressures (IOP) up 50 mm Hg similarly (r2 0.949 0.967, IOP 100 Hg. pneumatonograph also exhibited high reliability, r2 0.936 (closed) 0.898 (open), at 0.932 0.948 (open) least satisfactory for eye, ranging 0.069 0.171.
