Chlorpromazine is a medication widely used in psychiatry for the treatment of psychoses, especially schizophrenia. Since 1964, published articles have been correlating this medication with the appearance of ocular alterations. In this paper, we report the case of a 65-year-old patient with ocular effects due to long-term therapy with chlorpromazine. Biomicroscopy of both eyes presented diffuse granular brown deposits, most prominent at the deep stroma and corneal endothelium level. Also showed anterior subcapsular brown deposits with a stellate pattern in the lens. The total amount exceeds 2.000g (significant for the ocular alterations described) considering the patient's daily dosage of chlorpromazine of 300mg for ten years. After performing complete ophthalmic evaluation and discarding other causes for the ocular deposits, we diagnosed a secondary corneal deposit and cataract due to the use of chlorpromazine. This case reinforces the importance of periodic follow-up with an ophthalmologist for chlorpromazine users to trace ocular changes, heeding the exposure time and its dosage. [ABSTRACT FROM AUTHOR]
