Damage and death of these nerve cells, or neurons, leads to characteristic features of optic neuropathy. The main symptom is loss of vision, with colors appearing subtly washed out ...
A subconjunctival hemorrhage appears as a bright red patch on the white of the eye and is commonly referred to as a burst blood vessel. In hyphema, blood pools in the anterior chamber, where the iris (the colored part of the eye) and the pupil are located. Hyphemas are graded based on the amount of blood covering the cornea.
Periorbital dark circles. Minor dark circles and a hint of periorbital puffiness —a combination principally suggestive of minor sleep deprivation. Periorbital dark circles (including dark circles of the lower eyelid) are dark blemishes around the eyes. There are many causes of this symptom, including heredity and bruising.
Now there’s a new concern to add to the list: It may raise your risk of developing a blinding eye condition. That’s the major takeaway from a new study published in JAMA Ophthalmology .
