The left eye received a single PDT session with topical a lipophilic methyl ester derivative of 5\u2010aminolevulinic acid (160\u2009mg\/g) and red LED light, while the right eye received two sessions, followed by adjuvant ECT with intravenous bleomycin.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The lesion in the left eye presented with pallor associated with mild inflammation after the PDT session, with complete resolution in the following days and recovery of its normal clinical appearance. In the right eye, the first two PDT sessions resulted in significant regression of the neoplastic lesions.
