Optic neuropathy is damage to the optic nerve from any cause. The optic nerve is a bundle of millions of fibers in the retina that sends visual signals to the brain. 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 ...
All participants provided blood samples and were given physical exams. After adjusting for various risk factors and education levels, researchers found that women with a higher diastolic blood ...
Intraocular hemorrhage (sometimes called hemophthalmos or hemophthalmia) is bleeding inside the eye ( oculus in Latin ).
