PURPOSE: To evaluate the visual field changes in blue-on-yellow perimetry (B/Y) strategy 10-2 in alcohol and tobacco smoking consumers. METHODS: Forty-two eyes of twenty-one users were studied. Fifteen individuals were used as a control group. All volunteers were males. After normal ophthalmologic examinations, central 10-2 (B/Y) was performed in both eyes. Analysis of the results was performed through the alterations in the depth graph defect and number of altered points. RESULTS: It was found that the majority of the chronic alcohol and tobacco smoking consumers had a greater frequency of alterations in the depth graph defect; 40 eyes (95.3%), (>10dB), and 27 eyes (64.3%) showed a number of altered points, (>10 points), (p<0.0001). All those who were used as a control group showed alterations in the depth graph defect and number of altered points, but had less than 10dB and 10 altered points, respectively. CONCLUSION: A higher number of abnormal points and depth graph defects and number of altered points were observed in alcohol and tobacco smoking consumers reflecting a higher number of alterations in the cells of the parvocellular system, responsible for color function, by B/Y perimetry.
