The optomap ultra-widefield retinal image is a unique technology that captures more than 80% of your retina in one panoramic image while traditional imaging methods typically only show 15% of your retina at one time. The benefits of having an optomap ultra-widefield retinal image taken are:
Nephrostomy Tube Care. A nephrostomy tube is a drainage tube placed into the kidney to drain urine directly from the kidney. The word nephrostomy comes from two Latin root words for kidney (nephr) and new opening (stomy).
In recent years, some surgeons are using tube shunts or glaucoma drainage devices as first-line surgery, and forgoing standard trabeculectomy surgery. The cost of tube shunt implantation is somewhat higher than for trabeculectomy; however, some would argue there are fewer risks.To weigh these factors, there is currently an ongoing trial comparing tube shunt versus trabeculectomy in patients who have had no prior ocular surgery.his article is one in a series looking at treatment options for glaucoma. Last monthâs âInsightsâ (March 2014) looked at another type of shunt, the metal ExPRESS device, used in combination with trabeculectomy.
