Development Of The Diode Laser PDT Device For The Ocular Fundus Diseases

With people aging, Age-related Macular Degeneration ( ARMD) has increasingly been a serious ophthalmology occoecatio disease. The particular physiological nature in ocular region has determined that laser therapy has advantage in ARMD. As a new technology, Photodynamic therapy(PDT) has been considered a ideal method in ARMD.With the function of photochemical, Photodynamic therapy can be used to treat the ARMD by closing down the CNV that secondary to the ARMD. It overcomes the deficiencies of photocoagulation therapy and TTT, and has shown its advantages in treating most kinds of ARMD with little side-effects. At present, Visudyne is the main photosensitizer. It's very expensive and some experimental data shows that it's not a very suitable agent for the ARMD's treatment. Now, the domestic photosensitizer HpD has got the admission to the clinical applications. It's low cost and shows more advantages in this treatment. However, we seldom have the related reports on it applied to this treatment. The main reason is that there's no available devices to match HpD in the clinical application, no matter domestic or overseas. So we designed the PDT laser device in order to meet the clinical urgent requirements, it can be matched with various photosensitizers, including the HpD, by changing some parameters of the hardwares and the optical system.In order to meet the clinical requirements, In the design, we has taken new touching screen technology into the PDT diode laser for ocular fundus,...
