From: A review of the application of in-vivo confocal microscopy on conjunctival diseases
Representative in-vivo confocal microscopy (IVCM) images of conjunctiva-associated lymphoid tissue (CALT) from a normal subject and a 52-year-old male with herpes simplex virus keratitis. a The diffuse lymphoid layer of the healthy subject shows a low density of highly reflective lymphocytes. b The lymphoid follicles of the healthy subject manifested as round-shaped with a low density of lymphocytes inside. c The diffuse lymphoid layer of the infectious keratitis patient presented as an infiltration of numerous hyperreflective lymphocytes. d Lymphoid follicles of the infectious keratitis patient showed irregular-shaped follicles, a greater number of parafollicular lymphocytes, and a larger follicular area
