A diode laser, which emitted infrared radiation at a wavelength of 810 nm, was used to perform trabecular photocoagulation in a human eye due for enucleation for malignant melanoma. For comparison, burns were applied with an argon blue-green laser (488-514.5 nm). With each laser, the treatment spot size was 100 nm and the pulse duration was 0.20 sec. Visible lesions were produced with a power o...

The binocular indirect argon laser photocoagulator was newly designed to enable visualisation of the entire fundus during panretinal laser photocoagulation and to treat retinal tears immediately after buckling procedures of the sclera. The lamp housing of the binocular ophthalmoscope was remodelled and adjusted so that the laser beam and illuminating light are coaxial after leaving the ophthalm...

Purpose: To compare the histhologic changes in the retina and chowid, between the continuous and pulsed-wave photocoagulation by diode laser in pigmented rabbits. The r6petitivepulse photocoagulation could prove to be a promising technique for several pathologies in the ocular fundus. Methods: Continuous and pulsed diode-laser transpupillary photocoagulation~ was performed in the eyes of pigmen...

Histologic study of lesions produced by krypton red (647.1 nm) and krypton yellow (568.2 nm) laser lights reported here suggests advantages in alternating these two wavelengths in photocoagulation. Selection of the best wavelength to be used in a given location on the retina should result from pre-determined absorbance conditions in that location. The feasibility of the relative measurement of ...

Diode laser treatment for retinopathy of prematurity was successful in 81% of 21 eyes with 'threshold' (zone 2, stage 3+) disease. This compares favourably with cryotherapy and argon laser photocoagulation. The retinal outcome and technique are discussed.

BACKGROUND The purpose of this study was to evaluate and compare clinical outcomes and retreatment rates using navigated macular laser versus conventional laser for the treatment of diabetic macular edema (DME). METHODS In this prospective, interventional pilot study, 46 eyes from 46 consecutive patients with DME were allocated to receive macular laser photocoagulation using navigated laser. ...

Panretinal photocoagulation (PRP) is a standard treatment for proliferative diabetic retinopathy. Conventional laser (CL) therapy is performed in one or more sessions in single spot mode. Visual disabilities have been reported after treatment with CL, including central vision loss due to macular edema and peripheral visual field loss resulting from extensive inner retinal scarring. Multispot la...

PURPOSE The purpose of this study was to perform a reference case (average case), cost-utility analysis of laser photocoagulation for extrafoveal choroidal neovascularization associated with age-related macular degeneration using a model incorporating patient preferences. METHODS Visual acuity data for patients treated and observed over a 5-year period were obtained from previously reported s...

PURPOSE To evaluate the analgesic effect of topical sodium diclofenac 0.1% before retinal laser photocoagulation for diabetic retinopathy. METHODS Diabetic patients who were candidates for peripheral laser photocoagulation were included in a randomized, placebo-controlled, intraindividual, two-period, and crossover clinical trial. At the first session and based on randomization, one eye recei...
