SUAREZ GARCIA, Viviana et al. Correlation of Heidelberg´s retinal tomograph and blue-on-yellow perimetry in glaucoma-suspected patients. Rev Cubana Oftalmol [online]. 2009, vol.22, n.2, pp. 43-50. ISSN 1561-3070.

OBJECTIVE: To assess the correlation between the results achieved with the Heidelberg retinal tomography and the blue-on-yellow perimetry in glaucoma-suspected patients. METHODS: A prospective longitudinal and descriptive study was conducted on 30 glaucoma-suspected patients, from November 2006 to April 2007. Three topographic tests and three perimetric tests were performed on these patients in a 6-month period at 2- month intervals. RESULTS: Over 40 years of age prevailed (56,67 %). Topographic findings indicative of glaucoma were observed in 63,3 % of the sample and the most frequent were excavation higher than 0,6 in the vertical axis and the reduction of the neuroretinal ring (56,67 % in both cases). Perimetric changes appeared in 43,3 % in all the studied cases and the most common changes were increase of the blind spot and the general loss of sensitivity (10 %) in the first study, and also in the second study (13,33 %); the third study similarly yielded a general loss of sensitivity in 43,33 % of patients. CONCLUSIONS: Topographic changes occurred before the perimetric changes in a high number of cases.
