Glaucoma: Present Challenges and Future Trends

The authors indicate four key issues which, in their opinion, represent the most stimulating challenges in the field of glaucoma today, and describe the present approaches and the developments that can be expected or advised in the near future: (1) Glaucoma is often undiagnosed or diagnosed too late. Accurate detection is crucial to correctly recognize and treat affected subjects, thus reducing the disability and the social burden of the disease. Is glaucoma screening advisable and cost-effective? What strategies can be implemented to achieve an earlier diagnosis? (2) What role can genetics play in glaucoma clinics? (3) What are the fundamentals and the limits of medical hypotensive and nonhypotensive treatment of glaucoma today, and what novelties could be introduced in the next few years? (4) What are the current and future options for glaucoma surgery? Should we aim at reducing aqueous production or at enhancing aqueous outflow? What are the success figures and the pros and cons of ab externo procedures with external filtration (trabeculectomy, nonpenetrating techniques and glaucoma drainage devices) and of ab externo techniques with internal filtration (viscocanalostomy and canaloplasty)? Will microinvasive procedures ever play a role in the treatment of the disease? These questions and the possible future developments in the management of glaucoma are discussed critically, based on the current clinical state of the art, on a review of the literature, and on an everyday experience in a busy university hospital glaucoma service.
