General Questions

Cataracts are  the clouding of the lens of your eye , which is normally clear. Most cataracts develop slowly over time, causing symptoms such as blurry vision. Cataracts can be surgically removed through an outpatient procedure that restores vision in nearly everyone.

The cornea is the outer clear, round structure that covers the iris and the pupil. The cornea directs light rays into the eye and helps focus them on the light-sensitive retina at the back of the eye, providing sharp, clear vision. The lens is located behind the iris and is normally clear.

Client Query

People who have been in an extended medical care facility and are returning to society after many years are not aware of how living by themselves will be after a long duration. Counselors at the extended medical care facility should provide guidelines to live by and make the patient abreast of the things that have to be done when they go back to living in society.

The care of nurses/doctors and the professionalism of administration and ancillary staff members impact patient satisfaction. Ask this question to know whether your staff was courteous and professional and if proper assistance was provided to the patient.

Technical Questions

The human cornea is comprised of six different cell layers: Epithelium, Bowman's Layer, Stroma, Dua's Layer, Descemet's Membrane and Endothelium. The epithelium is the outermost layer of the cornea and accounts for about 10% of the cornea tissue's thickness.

The transparent cornea forms the anterior portion of the outer casing of the eye and has the dual functions of protecting the inner contents of the eye as well as providing about two thirds of the eye's refractive power. ... In normal corneas most of these are so thin that light scattering is minimal.

The cornea has no blood supply of its own, so it gets oxygen only from tears and directly from the atmosphere. A contact lens reduces the oxygen supply to the cornea, making the cornea swell.

The mechanism of open-angle glaucoma is believed to be  the slow exit of aqueous humor through the trabecular meshwork , while in closed-angle glaucoma the iris blocks the trabecular meshwork. The diagnosis is achieved by performing a dilated eye examination. Often, the optic nerve shows an abnormal amount of cupping.

It is important to understand that glaucoma cannot be cured, but it can usually be controlled. With proper treatment over 90% of patients can have their disease stabilized and less than 5 % will lose all vision.

Our study found that the most common symptoms reported by all patients, including those with early or moderate glaucoma, were needing more light and blurry vision. Vision loss in patients with glaucoma is not as simple as the traditional view of loss of peripheral vision or “tunnel vision.”
