Comparative analysis finds high correlations in intraocular pressure measurements among various tonometers, suggesting reliable alternatives.
The Goldmann, Mackay‐Marg, and Non‐contact tonometers were compared on 25 subjects to establish correlations between measurements of intraocular pressure by these instruments. Topical anesthetic was used for the Goldmann and Mackay‐Marg readings only. Correlations were high: between the Goldmann and the Non‐contact, +0.93; between the Mackay‐Marg and the Non‐contact, +0.81; and between the Goldmann and the Mackay‐Marg, +0.87.
