is a rare form of nearsightedness
in which the back of the eyeball continues to grow longer after reaching normal adult size. It is usually progressive
. About 3%
of the world population are affected by this condition. People with pathological myopia have very rapid changes in their vision.
Main risk factors for pathological myopia are greater axial length
. Other possible risk factors include:
- Female gender
- Larger optic disc area
- Family history of myopia
Since the elongation of the eyeball cannot be controlled, treatment options are limited. While laser radiation
can prevent progressive damage to retina by destroying abnormal growing of blood vessels, it may also affect the healthy retinal tissues. Photodynamic therapy
is currently a safer treatment option, in which drugs will be injected to your retina at regular intervals.
In addition, people with low vision can reduce that influence on their daily life by using visual aids
such as magnifying glass for near tasks and telescopes for distance vision.
If you are experiencing loss of vision
, go to see your doctor and ask for medical help as soon as possible.
