Most of the glaucoma patients were on prostaglandin analog treatment.Results: Mean applanation intraocular pressure in the control group was 14.28 mmHg for the right eye and 14.10 mmHg for the left eye (P &gt; 0.05). Corneal thickness was 519.10 &micro;m for the right eye and 511.07 &micro;m for the left eye (P &gt; 0.05). Mean dynamic contour tonometry intraocular pressure was 17.28 mmHg for the right eye and 17.25 mmHg for the left eye (P &gt; 0.05). Mean ocular pulse amplitude was 2.80 mmHg for the right eye and 2.92 mmHg for the left eye (P &gt; 0.05).Conclusion: No differences in ocular pulse amplitude were found between the two groups and between the worst and the best eye. In spite of there being no difference in ocular pulse amplitude, dynamic contour tonometry intraocular pressure was 2.44 mmHg higher in the worst eye than in the best eye in the glaucoma patients, even with the same applanation intraocular pressure. Further studies are needed to confirm if this difference is related to glaucoma progression or a worst prognosis and whether it can be considered to be a new risk factor.Keywords: dynamic contour tonometry, central cornea thickness, assymetric glaucomaParchen MARPenha DAgostini Netto JBatista WDCarlier DSuzuki CLBSuzuki Jr ERDove Medical PressarticleOphthalmologyRE1-994ENClinical Ophthalmology, Vol 2012, Iss default, Pp 555-559 (2012)
