[Antiangiogenic therapy at the ocular surface: when, what and why?].

There are numerous indications for local antiangiogenic therapy at the ocular surface. These include vision-limiting corneal neovascularization, corneal blood and lymphatic vessels endangering corneal graft survival and tumor-associated lymphangiogenesis. A literature review in PubMed and own clinical and experimental data form the basis for a discussion of the indications, current therapeutic options and potential side-effects of local antiangiogenic therapy at the ocular surface.
