Abstrakt

Zwyrodnienie plamki związane z wiekiem jest najczęstszą przyczyną utraty widzenia centralnego. Proces chorobowy obejmuje region plamkowy siatkówki i prowadzi do znacznego pogorszenia ostrości wzroku, a co za tym idzie – również jakości życia. Chory traci możliwość wykonywania dotychczasowego zawodu, czytania, oglądania telewizji czy prowadzenia samochodu. Schorzenie to jest wyraźnie powiązane z procesami starzenia się i degeneracji tkanek, zazwyczaj pojawia się po 50. r.ż. Dopiero kilka lat temu wprowadzono środki farmakologiczne i inne metody terapeutyczne, które zdecydowanie poprawiły szansę na zachowanie użytecznej ostrości wzroku. Przełomowym odkryciem było klinicznie potwierdzone zahamowanie endotelialnego czynnika wzrostu, powodującego neowaskularyzację, co skutkowało brakiem wzrostu nieprawidłowych naczyń i w efekcie chroniło nie tylko przed spadkiem ostrości wzroku, ale nawet tę funkcję poprawiało. To była prawdziwa rewolucja w okulistyce, która dała pacjentom nadzieję na całkowite wyleczenie. Ale czy leczenie może przywrócić pełną ostrość wzroku? Czy tylko na krótko powstrzymuje ono postęp schorzenia? Wydaje się, że wiedza na temat genetycznego podłoża, patofizjologii, możliwości podawania nowych leków i wykorzystanie wszystkich metod terapeutycznych, łącznie z chirurgią, zastosowane na odpowiednim etapie rozwoju choroby coraz bardziej zbliżają nas do osiągnięcia sukcesu terapeutycznego. Ale sukces ten to powstrzymanie postępu choroby, a nie całkowite wyleczenie z odzyskaniem pełnej ostrości wzroku.
