Retinal laser photocoagulation.
Since its discovery in the 1940s, retinal photocoagulation has evolved immensely. Although the first photocoagulators utilised incandescent light, it was the invention of laser that instigated the widespread use of photocoagulation for treatment of retinal diseases. Laser permits choice of electromagnetic wavelength in addition to temporal delivery methods such as continuous and micropulse mode...
متن کاملCorneal sensitivity in diabetic patients subjected to retinal laser photocoagulation.
PURPOSE To determine the changes in corneal sensitivity to different stimulus modalities in diabetes mellitus (DM)1 and DM2 patients with retinopathy, and to explore whether argon laser photocoagulation exacerbates sensitivity loss in diabetic patients. METHODS Corneal sensitivity to different modalities of stimulus was determined in one randomized eye in 52 patients with DM1 (n = 35) or DM2 ...
متن کاملChanges in colour contrast sensitivity associated with operating argon lasers.
A new test of colour vision using computer graphics has been used to obtain quantitative estimates of colour contrast sensitivity in ophthalmologists before and after they have treated patients by argon laser retinal photocoagulation. The colour vision of all subjects is normal when tested with the 100-hue test and HRR (Hardy, Rittler, Rand) plates, but colour contrast sensitivity measured alon...
متن کاملSOPHOCLE: A Retinal Laser Photocoagulation Simulator: Overview
Retinal laser photocoagulation has been used for a decade, but no real improvement in results has been observed.The simulator described in this paper, by separating actual practice from apprenticeship, allows one both to learn how to manipulate the equipment and to train oneself for making a diagnosis and operating. It has been designed as close as possible to the actual operation conditions an...
متن کاملBarrier Laser Photocoagulation for Recurrent Retinal Detachment
Objective: To describe results of barrier laser photocoagulation in preventing progression of recurrent retinal detachment. Methodology: Prospective review of five patients with recurrent retinal detachment confined to the peripheral inferior retina. Three rows of barrier argon laser photocoagulation of moderate intensity white burns were performed. Patients were observed carefully after laser ...
