Modern retinal laser therapy.
Medicinal lasers are a standard source of light to produce retinal tissue photocoagulation to treat retinovascular disease. The Diabetic Retinopathy Study and the Early Treatment Diabetic Retinopathy Study were large randomized clinical trials that have shown beneficial effect of retinal laser photocoagulation in diabetic retinopathy and have dictated the standard of care for decades. However, ...
متن کاملNondamaging Retinal Laser Therapy: Rationale and Applications to the Macula.
PURPOSE Retinal photocoagulation and nondamaging laser therapy are used for treatment of macular disorders, without understanding of the response mechanism and with no rationale for dosimetry. To establish a proper titration algorithm, we measured the range of tissue response and damage threshold. We then evaluated safety and efficacy of nondamaging retinal therapy (NRT) based on this algorithm...
متن کاملSelective retinal therapy with a continuous line scanning laser
This study evaluates the effects of exposure duration, beam diameter, and power on the safety, selectivity, and healing of retinal lesions created using a continuous line scanning laser. A 532 nm laser (PASCAL) with retinal beam diameters of 40 and 66 μm was applied to 60 eyes of 30 Dutch-Belted rabbits. Retinal exposure duration varied from 15 to 60 μs. Lesions were acutely assessed by ophthal...
متن کاملSubvisible retinal laser therapy: titration algorithm and tissue response.
PURPOSE Laser therapy for diabetic macular edema and other retinal diseases has been used within a wide range of laser settings: from intense burns to nondamaging exposures. However, there has been no algorithm for laser dosimetry that could determine laser parameters yielding a predictable extent of tissue damage. This multimodal imaging and structural correlation study aimed to verify and cal...
متن کاملLaser Therapy of Esophageal Carcinoma
SUMMARY 13 Consecutive patients who underwent endoscopic Nd - Y AG laser therapy for palliation of advanced esophageal cardnoma were treated between Oct 1989, and July 1991 , in Khatam - al -Anbia Hospital. All patients had severe dysphagia and conventional methods such as surgery , Radiotherapy and chemotherapy failed to treat them. Undoubtedly without laser therapy these patients did not see...
