OPHTHALMOLOGY

LOW VISION

Low vision is vision loss that's so severe, it can't be corrected with regular eyeglasses, contact lenses or surgery.

Besides age-related retinal conditions, there are many other possible causes of low vision, including conditions such as glaucoma and diabetes. Low vision may also result from cancer of the eye, albinism, stroke, eye trauma or a brain injury.

A person with low vision may find it difficult or impossible to accomplish activities such as reading, writing, shopping, watching television, driving a car or recognizing faces. 

Laser-assisted in situ keratomileusis (LASIK)

LASIK is a surgical procedure that uses a laser to correct nearsightedness, farsightedness, and/or astigmatism. In LASIK, a thin flap in the cornea is created using either a microkeratome blade or a femtosecond laser. The surgeon then folds back the hinged flap to access the underlying cornea (called the stroma) and removes some corneal tissue using an excimer laser.
LASIK solves myopia by correcting the corneal irregularities that cause it. Hyperopia (Farsightedness) Farsighted individuals have trouble reading up close or seeing objects near at hand. The farsighted eye is slightly shorter than a normal eye and has a flatter cornea, so distant objects focus behind the retina

GLAUCOMA

Glaucoma is a condition that causes damage to your eye's optic nerve and gets worse over time. It's often associated with a buildup of pressure inside the eye. Glaucoma tends to be inherited and may not show up until later in life.
The most common type of glaucoma, primary open-angle glaucoma, is hereditary. If members of your immediate family have glaucoma, you are at a much higher risk than the rest of the population. Family history increases risk of glaucoma four to nine times.
The eye disease glaucoma can cause severe headaches in some cases. 
Acute angle-closure glaucoma is a medical emergency. When you're diagnosed with this condition, you'll need urgent treatment to reduce the pressure in your eye. This generally will require both medication and procedures. You may have a procedure called a laser peripheral iridotomy.
