Objective: to determine the usefulness of microperimetry and of the optical coherence tomography in the detection of subclinical retinal damage due to chloroquine. Methods: prospective, observational and analytical study in patients taking chloroquine, who were seen at the Neuro-ophthalmology service of "Ramón Pando Ferrer" Institute of Ophthalmology from September 2010 through October 2011. Forty four eyes were included. Tests were performed to assess function (visual psychophysics and microperimetry) and structure (biomicroscopy and optical coherence tomography). Results: mean age was 43 years with a cumulative dose of 182 g and less than 5 years taking this drug. There was significant correlation between the cumulative dose of chloroquine and the following variables: color vision (-0.495, p = 0.001), temporal peripapillary retinal thickness (-0.353, p= 0.019) and lower (-0.336, p = 0.026), central macular (-0.652, p = 0.000) and retinal sensitivity by microperimetry (-0.436, p= 0.003) with functional and structural changes related to the increase in cumulative dose. Conclusions: it was demonstrated that it is possible to detect early functional retinal damage by using microperimetry and optical coherence tomography in patients taking chloroquine, despite normal results of other functional studies and of biomicroscopy. The combination of microperimetry and optical coherence tomography may be a useful screening tool for retinal toxicity.
