Abstract

Objectives: Aromatic hydrocarbons are compounds that can affect the Central Nervous System (CNS), cause neurotoxicity and be associated with alterations in visual function. Course objective: To establish the frequency of alterations in contrast sensitivity (SC) and stereopsis, in a group of exposed workers and a group not exposed to aromatic hydrocarbons. Materials and methods: cross-sectional analytical study. Sample: control group 20 subjects, average age 25; exposed group 20 subjects, mid age 33.4. An optometric assessment was performed; the low visual pathways were evaluated through an SC test with the FACT test (Functional Acuity Contrast Test) and the intermediate visual pathways by stereopsis with the Frisby test. Results:There is a clinically and statistically significant difference for the values of the spatial frequencies of 3.0 cpd, 6.0 cpd and 12.0 cpd, of the control group compared to the exposed group, as in the fine stereopsis.
