Title:

Retinal Detachment: Causes, Symptoms, Diagnosis and Treatment.

Description:

Retina is a layer of tissue at the back of the eye, which helps to see images focused on it by the cornea and lens. Retinal Detachment is an eye disorder, wherein the retina gets separated from the underlying layer of blood vessels, which supplies oxygen and other nutrients to it. When the retina gets detached, the supply of oxygen and nutrients are stopped. If the condition is left untreated, it may even lead to a complete vision loss and blindness.

Title: Retinal Detachment: Causes, Symptoms, Diagnosis and Treatment.


1
RETINAL DETACHMENT
  • causes, symptoms, diagnosis and treatment

2
What is Retinal Detachment ?
  • Retina is a layer of tissue at the back of the
    eye, which helps to see images focused on it by
    the cornea and lens. Retinal Detachment is an eye
    disorder, wherein the retina gets separated from
    the underlying layer of blood vessels, which
    supplies oxygen and other nutrients to it. When
    the retina gets detached, the supply of oxygen
    and nutrients are stopped. If the condition is
    left untreated, it may even lead to a complete
    vision loss and blindness. There are three types
    of retinal detachment
  • rhegmatogenous
  • tractional
  • exudative
  •  

3
Symptoms of Retinal Detachment 
  • Sudden appearance of flashing bright lights,
    especially in the peripheral vision
  • Vision becomes blurred
  • The individuals experience illusions that some
    small objects like spots, hairs, or strings ,are
    moving in the eye (called floaters)
  • Blindness in the affected eye
  • A shadow keeps appearing in the vision field

4
Causes for Retinal Detachment
  • Bending or drooping of the vitreous that can
    occur with advancing age, due to a change in its
    consistency
  • Advanced stages of diabetes
  • Trauma/injury to the eye
  • Any eye inflammatory disorder may trigger retinal
    detachment

5
Risk Factors of Retinal Detachment
  • Adults above the age of 40 years
  • A previous occurrence of retinal detachment
  • A family history of the condition
  • Individuals with severe nearsightedness
  • Any previous eye surgery, like cataract removal
  • Congenital abnormalities affecting the eye
  • Any trauma or eye injury (including head injury),
    experienced previously
  • Use of certain eye drops (like pilocarpine for tre
    atment of glaucoma - a condition of elevated eye
    pressures)
  • Certain disorders affecting the eye, such as
    chronic inflammation of the eye (known as
    uveitis)
  • Participation in certain rough/contact sports,
    like boxing

6
Diagnosis of Retinal Detachment 
  • Physical examination and evaluation of complete
    medical history
  • Electroretinogram
  • Measuring the intraocular pressure
  • Fluorescein angiography
  • Ophthalmoscopy
  • Refraction test
  • Retinal photography, which aims to project the
    photographs of the inner surface of the eye
  • Visual acuity
  • Slit-lamp examination
  • Ultrasound of the eye

7
Treatment of Retinal Detachment
  • Most individuals suffering from retinal
    detachment would need a surgery, either
    immediately or after a short time. When the eye
    condition is mild, then surgery may be performed
    using lasers to close the holes/tears in the
    retina or Pneumatic retinopexy in which gas
    bubbles are placed in the eye, in order to make
    the retina go back to its original place. 

8
Prevention of Retinal Detachment
  • Use of protective eye wear is recommended, when
    working with hammers, lawn mowers, weed-eaters,
    fireworks, or any similar equipment that can
    cause an eye injury
  • All diabetic individuals are advised to keep
    their sugar level under control consistently
  • Consultation with an eye specialist at least once
    a year is recommended, especially for elderly
    adults and those who are at risk for a retinal
    detachment
