METHODS 14 cases were collected prospectively and triaged by ophthalmic nurses before referral to an ophthalmologist for a complete ophthalmic examination. Over time, such injuries can cause vision to deteriorate completely. If treatment is required then thermal laser or photodynamic therapy (PDT) may be used. The greater a laser pointer's output power, the more likely it will cause serious eye injuries, burn skin and temporarily - or permanently - impair the vision of pilots, drivers or bystanders. That much is clear. The resulting retinal damage caused "acute, dramatic" symptoms. Laser pointer maculopathy is the result of laser injury to the retina. The degree of damage depends on how much light reaches the back of the eye, the color of the laser, and how long the exposure is.
