Amblyopia which is also widely known as lazy eye
There are three types of amblyopia, based on the underlying cause:
- Strabismus is the most underlying cause of amblyopia. This type of amblyopia is called strabismic amblyopia.
- Refractive amplyopia. Sometimes, amblyopia is caused by unequal refractive errors in the two eyes, despite perfect eye alignment. For example, one eye may have significant uncorrected nearsightedness or farsightedness, while the other eye does not. Or one eye may have significant astigmatism and the other eye does not.
- Refractive amblyopia. Sometimes, amblyopia is caused by unequal refractive errors in the two eyes, despite perfect eye alignment. (or anisometropic amblyopia).
- Deprivation amblyopia. This is lazy eye caused by something that obstructs light from entering and being focused in a baby’s eye, such as a congenital cataract.
Treatment of amblyopia
Refractive amblyopia treatment
some cases of refractive amblyopia, normal vision can be achieved by correcting the refractive errors fully in both eyes with glasses or contact lenses. Usually, however, at least some patching of the “good” eye is needed to force the brain to pay attention to the visual input from the amblyopic eye and enable normal vision development to occur in that eye.
Strabismic amblyopia treatment
involves strabismus surgery to straighten the eyes, followed by eye patching and often some form of vision therapy to help both eyes work together equally as a team.
What is the importance of Early Detection And Treatment
Medical experts agreed that early detection and treatment of lazy eye is preferred for normal visual development and the best visual outcomes from amblyopia treatment.
The American Optometric Association recommends that “all children have their first eye exam at 6 months of age, another exam at age 3 and a third exam prior to entering school to ensure vision is developing normally in both eyes and there is no risk of amblyopia.”
