Vision Problems

Normal sight includes central vision (the field of view straight ahead) and peripheral vision (the field of view outside the circle of central vision). The inability to see within a normal range of view often indicates peripheral vision loss. In severe cases of peripheral vision loss, individuals only see with their central vision, which causes … Read more

Sometimes, a very thin flap is made in the cornea, so the ophthalmologist can access and reshape the cornea underneath. Afterwards, the flap … Read more

To gain the most benefits of these medications, use them exactly as prescribed by your eye doctor. Sometimes your doctor may prescribe more than … Read more

Glaucoma is a condition characterized by excessive pressure in the eye, or intraocular pressure. This irregularly high pressure is due to a buildup of fluid in the eye. As intraocular pressure increases, it can compress the eye’s optic nerve, eventually leading to vision loss. Around 3 million people in the United States have glaucoma; although … Read more

Glaucoma is characterized by an excessive accumulation of fluid inside the eye, which leads to an increase in the inner eye pressure (intraocular pressure). This can damage the optic nerve and lead to a gradual … Read more
