Intra ocular pressure measurement with Goldmann applanation tonometer without using fluorescein: our results

ABSTRACT

The purpose of this prospective, double blind study was to evaluate a modified technique of Goldmann applanation tonometry without the use of fluorescein and compare these results when Goldmann applanation tonometry was done with fluorescein in same patients. The intraocular pressure in 86 eyes of 43 patients was measured with and without fluorescein by Goldmann applanation tonometry. Goldmann applanation tonometry without fluorescein underestimated IOP levels by 1 mm Hg. The modified technique of Goldmann applanation tonometry without fluorescein reflects standard Goldmann tonometry with fluorescein after a correction factor of + 1 mm Hg
