Title: Mydriasis: Causes, Symptoms, Daignosis, Prevention and Treatment

Mydriasis

Mydriasis
  • Mydriasis is generally referred to as an eye
    condition in which the pupil of the eye of a
    person finds difficulty in countering light and
    they become smaller than they normally ought to
    be. In mydriasis, the pupils open and close when
    exposed to light and dimness. Dilation or
    broadening of the pupil is usual in situations of
    low light for allowing more light to reach the
    retina. In case of mydriasis, the muscles play a
    vital role for opening as well as closing the
    colored portion of the eye, also called the iris.
    When this process gets disturbed, the pupil takes
    more time to shrink.

Causes of Mydriasis
  • Mydriasis is habitually produced by stimulant
    use, such as caffeine, amphetamines and different
    stimulating elements. It is also likely to happen
    through epileptic confiscations. The trauma of
    the head and neck too harm the cranial nerves,
    which hoard the eyes cause this
    problem. Mydriasis can turn out to be an
    identification of brain swelling, which is the
    result of ocular nerves pressure. There are some
    other general conditions too like aneurysm,
    fungal and viral infections, botulism and
    conditions that are capable of damaging nerves
    and brain tumors cause mydriasis.

Symptoms of Mydriasis
  • People who are affected by mydriasis are very
    much sensitive to light. As in mydriasis, the
    pupil doesnt narrow to block extra light and the
    exposure to light turns out to be much
    painful. Moreover, the patients suffering from
    mydriasis gets blurred vision as the pupil is
    needed to shrivel in the light for illuminating
    the vision. In the majority of situations,
    affected people do not ever sense any symptom.
    The most noticeable symptom of mydriasis is
    obviously pupil dilation.

Treatment of Mydriasis
  • Usually, mydriasis is treated by discovering and
    curing the condition responsible for it. When
    mydriasis is caused due to brain injury or head
    trauma then the swelling of the brain is treated
    first. When mydriasis occurred is the result of
    exposure to drugs or chemicals, and then the
    physicians stop the use of these compounds. When
    mydriasis is produced by medicines for dilating
    the pupil for testing then the doctor advises the
    patient to keep himself away from direct sunlight
    by wearing sunglass so that the inner part of his
    eyes do not get affected. However, there are
    certain medicines, which can cure mydriasis when
    none of the aforementioned conditions are
    responsible and they are Scopolamine,
    phenylephrine drops, atropine, steroids,
    pilocarpine and sometimes a combination of
    scopolamine and atropine.
