Purpose
To evaluate corneal thickness in eyes with normal tension glaucoma.

Material and methods
CCT (measured by specular microscope Topcon SP2000P) was evaluated in 70 eyes of 39 patients with diagnosed NTG, 35 women and 4 men in age 31 – 78 years (mean 68 years).

Results
Mean central corneal thickness measured by the specular microscope (between 11 and 1), was 523,7 µm in range 465-575 µm. Impact of CCT on results of Goldman aplanation tonometry was detected in 55,7% of NTG eyes – overestimated in 20% and underestimated in 35% of them. Corrected maximal IOP > 21mmHg, was found in 14% of NTG eyes.

Conclusions
Central corneal thickness measurement should be part of routine ophthalmological examination in glaucomatous patients (specially in NTG), being helpful in choice of optimal therapeutic strategy.
