Seeing dark spots may indicate a potentially serious condition that merits concern, according to Mountain View Medical Center. A person should treat the sudden onset of dark spots as a medical emergency. Failure to seek immediate medical attention may result in a permanent loss of vision, reports WebMD.
Immediate medical attention is imperative if dark spots occur with other symptoms, such as a temporary loss of vision, flashes of light, pain in the eyes, or an increase in the number of dark spots following injuries or surgery, according to Mountain View Medical Center. Some people may tend to ignore what they perceive as simple, age-related spots, but early detection and treatment can retard the progression of critical conditions, according to WebMD.
