CO OZNACZA SŁOWO RETINOSCOPY
Retinoskopia
Retinoskopia jest techniką uzyskiwania obiektywnego pomiaru błędu refrakcyjnego oczu pacjenta. Ekspert używa retinoskopu, aby błyszczeć w oku pacjenta i obserwuje odbicie od siatkówki pacjenta. Przesuwając smugę lub punkt światła przez ucznia, obserwator zauważy względny ruch reflektora, a następnie używa phoroptera lub ręcznie umieszcza soczewki na oku, aby "neutralizować" odruch. Retinoskopia statyczna jest rodzajem retinoskopii stosowanej do określania błędu refrakcji pacjenta. Opiera się ona na zasadzie Foucaulta, która stanowi, że egzaminator powinien symulować nieskończoność optyczną w celu uzyskania prawidłowej mocy refrakcyjnej. W związku z tym energia odpowiadająca odległości roboczej odejmowana jest od wartości retinoskopii brutto w celu uzyskania stanu refrakcji pacjenta, przy czym obiektyw z odległością roboczą jest tym, który ma ogniskową odległość pacjenta od badacza. Myopy wykazują refleks "przeciw", co oznacza, że kierunek ruchu światła obserwowany z siatkówki jest inny niż kierunek światła, w którym wirowana jest wiązka światła.
Definicja słowa retinoscopy w słowniku
Definicja retinoskopii w słowniku jest procedurą wykrywania błędów refrakcji w oku za pomocą przyrządu, który odbija wiązkę światła od lustra do oka. Diagnozę przeprowadza się, obserwując obszary cienia i kierunek, w którym światło porusza się po obróceniu lustra. Nazywany również: skiaskopią, testem cienia.
