PURPOSE. To establish the real localization of rifabutin-related corneal deposits in a patient with human immunodeficiency virus (HIV) infection by in vivo HRT II confocal microscopy with related clinicopathologic implications. METHODS. Observational case report. After Siena University Institutional Review Board approval in May 2008 and specific informed consent, a 54-year-old patient with HIV infection under rifabutin treatment for acquired immunodeficiency syndrome-related Mycobacterium avium complex prevention who developed diffuse corneal deposits was examined at the Department of Ophthalmology of Siena University. He underwent a complete clinical eye examination, biomicroscopy, and digital slit lamp photographs, endothelial specular microscopy, ultrasound pachymetry, and confocal microscopy by HRT II system. RESULTS. Confocal scans revealed the presence of deep stromal and pre descemetic hyperreflective polymorphous deposits. In vivo confocal examination excluded the presence of rifabutin-related deposits at endothelial level. CONCLUSIONS. Confocal microscopy enables establishment of the real localization of rifabutin deposits at deep stromal level, providing a better qualitative analysis of all corneal layers compared to biomicroscopic examination, with clinical and physiopathologic implications. © Wichtig Editore, 2009.
