The Mackay-Marg, pneumatonograph, and EMT-20 tonometers were evaluated in the eyes of glaucomatous beagles. Tonometric scale readings were compared to the manometric recordings from the anterior chamber. Tonometry was performed with manometric system closed and open to the reservoir column. The Mackay-Marg tonometer evaluated in the closed and open manometric systems was highly reliable (goodness of fit [r2] = 0.852 and 0.816, respectively) with intraocular pressures up to 50 mm Hg and somewhat lower (r2 = 0.818 and 0.740, respectively) with intraocular pressures up to 100 mm Hg. The pneumatonograph also exhibited high reliability (r2 = 0.892 [closed] and 0.806 [open]) at pressures up to 50 mm Hg and (r2 = 0.796 [closed] and 0.75 [open]) at pressures up to 100 mm Hg. The EMT-20 tonometer was the least satisfactory for the glaucomatous globe, with r2 ranging from 0.235 to 0.654.
在患有青光眼的比格犬眼中对麦凯 - 马格眼压计、气动眼压计和EMT - 20眼压计进行了评估。将眼压计的刻度读数与前房的压力测量记录进行比较。眼压测量分别在压力测量系统关闭和通向储液柱开放的情况下进行。在封闭和开放压力测量系统中评估的麦凯 - 马格眼压计在眼压高达50毫米汞柱时具有高度可靠性（拟合优度[r2]分别为0.852和0.816），而在眼压高达100毫米汞柱时可靠性稍低（r2分别为0.818和0.740）。气动眼压计在压力高达50毫米汞柱时也表现出高可靠性（封闭时r2 = 0.892，开放时r2 = 0.806），在压力高达100毫米汞柱时（封闭时r2 = 0.796，开放时r2 = 0.75）。EMT - 20眼压计对于青光眼眼球的测量最不理想，r2范围为0.235至0.654。
