Ocular leprosy: from bench to bedside

PURPOSE OF REVIEW: Ocular manifestations of leprosy do occur despite advances in the areas of leprosy research. Understanding the nuances in the domain shall guide the clinician for effective patient-centered care. RECENT FINDINGS: Despite the existence of microbiologic cure for leprosy, ocular manifestations of this disease do occur. Advances in genetic and genomic studies have better characterized the interaction that the bacteria has with the host. The ocular features vary with the spectrum of the disease. Its careful correlation can help to predict the bacillary load of the patient. Investigations are particularly relevant in multibacillary cases. The WHO suggests a treatment duration longer than the 2 years in ocular involvement. SUMMARY: The isolation of lepra bacilli from the iris biopsy in negative skin smear patients and multidrug therapy completion highlights the potential role of bactericidal agents in the planned intraocular treatment. Lepra reactions need careful titration of oral steroids and appropriate antibacterial agents. Advances in phacoemulsification with in the bag implantation of intraocular lenses is a game changer in the management of the most common cause of blindness of leprosy. Advances in vaccine research in leprosy are promising.
