Final answer:
The observed flashes of light and floaters may indicate retinal detachment, which is a serious condition requiring immediate medical intervention. Laser surgery is often used to repair a detached retina by creating scar tissue that holds it in place.
Step-by-step explanation:
A patient wearing high myopic glasses since childhood observed flashes of light and floaters following a minor trauma to his eye. The first thing to do is to seek immediate medical attention. This symptomatology may be indicative of a retinal detachment, which is a serious condition and can lead to permanent vision loss if not treated promptly. Treatment may involve the use of a laser to focus on a small spot on the retina, creating scar tissue to hold it in place. This process through which the detached retina is repaired uses the eye's natural lens along with a device to direct the laser output precisely onto the damaged area.
