It occurs when the retina of your eye tears away from the back and loses its blood and nerve supply. After its occurrence, what is visible is flashing lights and black flecks followed by an area of blurred or absent vision.

The macula is the center of the retina. When abnormal vessels grow and cause leakage of blood and other fluids into the macula, this is wet macular degeneration. Its progress speed is fast and it can happen suddenly. Wet macular degeneration usually causes blurred vision and loss of vision in the center part of your visual field.
5. Angle closure glaucoma
When the drainage system of the eye is blocked and it creates pressure in the eye, then it is known as angle-closure glaucoma. It usually causes redness, pain, and nausea.
This problem is a medical emergency and requires immediate treatment. Its treatment includes eye drops to open the angle, decrease the pressure and inflammation. Sometimes, iridotomy (a laser procedure) is also suggested by doctors.

Inflammation in the cornea is a situation of keratitis. It usually happens because of an infection, using one pair of contact lenses for too long, or reusing dirty contacts.
13. Macular hole
The macula’s role in our eye is to balance central vision. If it tears or breaks, it can develop a blurry vision. It usually only affects one eye.
14. Migraine with aura
Migraine attacks are followed by an aura, which can cause blurred vision, wavy lines, or flashing lights.
15. Optic neuritis
The role of an optic nerve is to connect an eye with the brain. If there is an inflammation in the optic nerve, it will be a situation of optic neuritis.
16. Temporal arteritis
Inflammation in the medium-sized arteries is a situation of temporal arteritis. The vessels around your temples can cause a throbbing headache in your forehead, but it can also cause your vision to blur or disappear.
The uvea is a collection of pigmented structures in the eye including the iris. An infection or autoimmune reaction can cause it to become inflamed and painful, which is called uveitis.
