Please Note:
These sections are not intended to replace the professional examination and diagnosis by a physician, and they are presented here purely for informational purposes. All possible diagnoses and treatment options are not covered, and the information discussed should not be taken as a recommendation to self-diagnose and self-treat a condition. A misdiagnosed or improperly treated eye condition can result in a permanent loss of vision, or a permanent loss of function of the eye or visual system. In the case of any eye problem, seek medical attention promptly. This can include emergency room treatment, as well as treatment by a medical physician or eyecare provider.Sections Include:
