Delayed retinal effects of the frequency-doubled YAG laser (532 nm).
In order to compare the retinal effects of the frequency-doubled YAG laser (532 nm) with those of argon laser, rabbit eyes were exposed to green YAG laser irradiation and processed for light and electron microscopic study at 24 hr, 2 weeks and 4 weeks. Detailed analysis was conducted on tissue exposed to 7.3 and 7.6 millijoules (mj). Response of the photoreceptors and retinal pigmented epitheli...
متن کاملPhotodisruptive Nd:Yag laser in the management of premacular subhyaloid hemorrhage.
PURPOSE Premacular subhyaloid hemorrhage is usually a benign condition that generally improves spontaneously and rarely causes visual loss. However, because the hemorrhage may cause permanent macular changes before it resolves, Nd:YAG laser posterior hyaloidotomy may be indicated in selected cases. This study investigated the effects of drainage of premacular subhyaloid hemorrhage into the vitr...
متن کاملComparison between Peeling with Focal Trichloroacetic Acid and Quasi-Continuous Frequency-Doubled Nd:YAG (532 nm) Laser in the Treatment of Freckles
Background: Benign pigmented lesions, including freckles, are common and various treatment modalities including lasers and peeling have been evaluated for their effectiveness in their treatment.Objective: To compare the clinical effects of focal peeling with Trichloroacetic Acid (TCA) and Nd:YAG (532 nm) laser on freckles.Methods: Twenty patients with freckles were treated with foca...
متن کاملBilateral Premacular Subhyaloid Hemorrhage in Dengue Fever
A 13-year-old girl presented to the ophthalmology clinic complaining of painless decrease in vision in both eyes from two weeks before presentation. Visual loss had been accompanied by fever, muscle pain, chills and headache; however the patient had become afebrile four days before referral. Ocular examination revealed best corrected visual acuity (BCVA) of counting fingers in the right eye (OD...
متن کاملMolecular Iodine Spectra and Laser Stabilization by Frequency-Doubled 1534 nm Diode Laser
By using the second harmonic radiation of a 1543 nm diode laser, several predicted rovibronic transitions of molecular iodine were observed for the first time. We demonstrated that the absolute frequency of a 1534 nm external-cavity diode laser could be frequency-stabilized to a 1MHz instability (for one second averaging time) by locking the frequency of the second harmonic generation to the de...
