Primary congenital glaucoma (PCG) is an eye disease that affects children between the ages of birth and 3 years. It is one type of glaucoma. Glaucoma refers to a group of diseases that affect the eye and cause major damage to the optic nerve.
Primary congenital glaucoma is rare. It affects about one in every 10,000 infants. But it is serious and needs attention. Untreated primary congenital glaucoma is a major cause of childhood blindness.
"Primary" means the disease does not result from another...
refocus light entering the eye on the retina. Eyeglasses and contact lenses are
the treatment of choice for most people with nearsightedness. Both are safe and
effective and are less risky and less expensive than surgery. Some people find
that eyeglasses do not provide the same quality of central or side vision as
contact lenses. While contacts can provide excellent vision, they do carry a
risk of infection. So they require routine cleaning and maintenance.
Prescriptions for eyeglasses and contact lenses
specify both the shape and power of the lens.
Surgery changes the shape of the
cornea. Several procedures are available, such as
LASIK, photorefractive keratectomy, corneal ring implants, and intraocular lens
implants (IOLs). See the Surgery section of this topic for more

No single treatment is right
for everyone who is nearsighted. Consider the following general points in
deciding which option is right for you:
How predictable are the results (how reliably
does the treatment provide the exact amount of correction
How stable are the results? Does the correction change
What are the risks and potential
How much maintenance and self-care are
How convenient is the option? What is the cosmetic effect
(that is, how does it look on you)?
Age can be a factor. In the
United States, some surgical procedures are not approved for people younger
than 18 years of age. In people younger than 20, the eyes may still be changing
laser surgical procedures most commonly used to
correct nearsightedness cause permanent changes in the eye. They cannot be
reversed. Newer options such as corneal ring implants or intraocular lens
implants (IOLs) can be removed if needed.

Will the treatment affect your work or

Certain health conditions and medicines may affect the
outcome of surgical treatments. For example, autoimmune or immunodeficiency
diseases and some medicines may prevent proper healing after surgery. Other
conditions, such as pregnancy, diabetes, or use of steroid medicines, may cause
changes in vision.
Certain conditions in the eyes may affect your
choice of treatment. For example, people who have a history of
keratoconus, inflammatory eye diseases, herpes simplex
keratitis, or past eye injuries or surgeries should avoid surgery to correct
Should I have laser surgery for nearsightedness?
If you decide to have surgery, choose an
ophthalmologist who has low complication
rates or extensive experience in performing the type of surgery you will have.
Studies suggest that complications are not as likely to occur after surgery
performed by an experienced surgeon as after surgery performed by a surgeon
with less experience.3
