摘要：
Ophthalmic machine (500) characterized in that it comprises: - lighting means (1, 2) adapted to provide an excitation light (EL) having wavelengths comprised between 430 nm and 490 nm - scanning means (3) adapted to scan said excitation light (EL) on an eye retina (100)； - first filtering means (4) adapted to receive light (EM) emitted by the retina, when illuminated by said excitation light (EL), said first filtering means having a first blocking band (BB1) to block light (RL) with wavelengths corresponding to the wavelengths of said excitation light (EL) and a first passing band (BP1) to transmit light (FL) with wavelengths higher than the wavelengths of said excitation light, said first filtering means having an optical density higher than 6 in said first blocking band； - second filtering means (5) adapted to receive the light (FL) transmitted by said first filtering means, said second filtering means having a second blocking band (BB2) comprised in an interval of wavelengths higher than 600 nm and a second passing band (BP2) comprised in an interval of wavelengths lower than 600 nm, said second filtering means having an optical density lower than 3 in said second blocking band； - third filtering means (6) adapted to receive the light (FL) transmitted by said first filtering means, said third filtering means having a third blocking band (BB3) comprised in an interval of wavelengths lower than 570 nm and a third passing band (BP3) comprised in an interval of wavelengths higher than 70 nm, said third filtering means having an optical density lower than 3 in said third blocking band； - first detection means (7) adapted to receive a light (GFL) transmitted by said second filtering means (5) and provide first detection signals (D1) indicative of the light transmitted by said second filtering means； - second detection means (8) adapted to receive a light (RFL) transmitted by said third filtering means (6) and provide second detection signals (D2) indicative of the ligh
