Eye membrane inflammation generally refers to the whites of the eyes, which is conjunctivitis, while corneal inflammation refers to the black part of the eyes. Both conjunctivitis and corneal inflammation should be actively treated. The symptoms of conjunctivitis include red eyes, swelling, pain, tearing, photophobia, increased secretion, foreign body sensation, and burning sensation, generally not affecting vision. In addition to the above symptoms, corneal inflammation has more pronounced symptoms of corneal irritation, such as increased sensitivity to light and more severe tearing. If corneal inflammation is not actively treated, it may later lead to thinning of the cornea, spots, and opacities, severely affecting vision. If not treated properly, corneal ulcers can perforate, leading to complete loss of vision, or blindness.
