Visual Impairment

What is Visual Impairment?
  • Visual Impairment can be known as a condition in
    which an individual's ability to see things are
    not fine. This means that the function of the eye
    for various reasons may become limited. Visual
    Impairment can be referred to as anything ranging
    from not being able to see near or far things to
    partial or complete blindness. The power of an
    individual to see objects clearly is termed as
    the visual acuity of the person and is a basic
    criterion for diagnosing an individual with
    visual impairment. A visual field of an
    individual is the area that can cover which one
    can see clearly. This is yet another criterion
    for an individual to be diagnosed with visual
    impairment.

Different types of Visual Impairments?
  • Hypermetropia or far sightedness is a type of
    visual impairment in which an individual is not
    able to see objects that are far away from him or
    her.
  • Myopia or near sightedness is another type of
    visual impairment in which an individual is not
    able to see clearly the objects that are near to
    him or her.
  • Total blindness is a condition in which one is
    not able to see anything at all from both of the
    eyes.
  • Partial Blindness is a condition in which an
    individual is able to see to some extent from one
    eye.

What causes Visual Impairment?
  • There can be various causes for visual
    impairment of which some are mentioned below in
    which some are acquired and some are congenital.
    Some of the causes of visual impairment are Eye
    Injury A direct blow or injury to the eye while
    working or in sports or in a motor vehicle crash
    may result in visual impairment, especially
    injuries to the cornea which are quite
    common. Inherited Conditions There are also
    some cases in which visual impairment is an
    inherited condition. One such medical condition
    which is an inherited visual impairment is known
    to be retinitis pigmentosa. Eye Infection There
    are specific eye infections which if transmitted
    from mother to child can further result in visual
    impairment in the child.

What causes Visual Impairment?
Continue
  • Trachoma of the eyes caused by a contagious
    microorganism known as Chlamydia Trachomatis
    tends to also affect the eyes. This infection is
    mostly seen in countries with poor hygiene and
    sanitary conditions.

How is the cause of Visual Impairment diagnosed?
  • The diagnosis of the cause of visual impairment
    begins with knowing the history of the patient in
    which the doctor inquires about when the symptoms
    started and how bad is the eye sight. In order
    to do this, the ophthalmologist will carry out a
    set of tests to find out the cause of the visual
    impairment and formulate the best treatment plan
    for the patient. The next step will be to
    conduct an examination of the eyes in which the
    ophthalmologist will inspect the eyelids,
    conjunctiva, cornea, and lens.
