What Causes Conjunctivitis (Pink Eye)?

Conjunctivitis is a common infection that affects the eye. It can be described as a medical condition that involves the inflammation of the conjunctiva. When the conjunctiva’s blood vessels are swollen, they become more visible, which makes them appear pink or red.

Most children get conjunctivitis frequently. The infection is easily contagious, but it rarely signifies any severe medical condition. In most cases, conjunctivitis causes damage to the individual’s vision if not treated early. Fortunately, there are lifestyle changes that may help prevent this condition. However, it’s vital to understand the causes of pink eye to comprehend the ways to avoid it.

Here are the significant causes of pink eye:

Acute Angle-closure Glaucoma

Acute angle-closure glaucoma [1] is a severe eye condition that occurs when the eye’s fluid pressure increases rapidly. The major symptoms include red-eye, a sudden onset of severe unilateral eye pain or headache associated with blurred vision, nausea or vomiting, rainbow-colored halos around bright lights. A fixed midpoint pupil and a cloudy cornea with marked conjunctival injection would show up by the physical exam.
Conjunctivitis doesn’t always signify the prevalence of this condition, vision is always normal when the pink eye is caused by conjunctivitis, but pin eye that caused by severe glaucoma is more serious. It is important to consult the doctor when feeling pain in the eye alongside a red or pink eye. An ophthalmologist may recommend an eye drop to help.
