Corneal abrasion is a scratch on the clear front surface of the eye, the cornea. It is often caused by a foreign object, such as a fingernail, a piece of dirt, or a sports ball.

Tennis is a sport in which players hit a ball back and forth over a net. The ball can travel at high speeds, and if it hits the eye, it can cause a corneal abrasion.

The best way to prevent a corneal abrasion is to wear eye protection, avoid contact with foreign objects, and keep your eyes closed during sports.

The symptoms of a corneal abrasion include pain, redness, tearing, and blurred vision.

A corneal abrasion is usually treated with antibiotic eye drops, pain relievers, and surgery in severe cases.

Conjunctivitis is an inflammation of the conjunctiva, the clear membrane that covers the white part of the eye and lines the inside of the eyelids. It can be caused by bacteria, viruses, or allergies.

The symptoms of conjunctivitis include redness, swelling, itching, and tearing.

Conjunctivitis is usually treated with antibiotic eye drops, viral eye drops, or antihistamines, depending on the cause.

Glaucoma is a condition in which the pressure inside the eye is too high, which can damage the optic nerve and lead to blindness.

The symptoms of glaucoma include pain, redness, blurred vision, and tunnel vision.

Glaucoma is usually treated with eye drops, laser surgery, or surgery, depending on the severity of the condition.

Retinal detachment is a condition in which the retina, the light-sensitive tissue at the back of the eye, separates from the underlying choroid.

The symptoms of retinal detachment include flashes of light, floaters, blurred vision, and loss of vision.

Retinal detachment is usually treated with laser surgery or surgery, depending on the severity of the condition.
