Figure 1 Photodynamic eye lymphography. A: Photodynamic eye (PDE) lymphography of normal testis. The injected indocyanine is canalized into the local lymphatic network and is rapidly drained out of the subcutaneous scrotal tissue; B: PDE lymphography of lymphedematous testis. Indocyanine diffusively accumulates in the scrotal subcutaneous tissue as a consequence of the impaired lymphatic drainage.
