Glaucoma Diagnosis Gap in India

Description:

According to WHO, glaucoma is the prime cause for irreversible blindness in India. Glaucoma Diagnosis Gap in India highlights, about 1.2 million have been rendered blind and at least 12 million are affected. Glaucoma is a condition where an accumulation of fluid in the eye increases the intraocular pressure resulting in optic nerve damage. The prevalence of glaucoma increases with age. – PowerPoint PPT presentation

Title: Glaucoma Diagnosis Gap in India

Glaucoma Diagnosis Gap in India

  • According to WHO, glaucoma is the prime cause for
    irreversible blindness in India. Glaucoma
    Diagnosis Gap in India highlights, about 1.2
    million have been rendered blind and at least 12
    million are affected. Glaucoma is a condition
    where an accumulation of fluid in the eye
    increases the intraocular pressure resulting in
    optic nerve damage. The prevalence of glaucoma
    increases with age. In India, there is a gap in
    glaucoma diagnosis that needs to be bridged by
    increasing awareness about the disease.
  • There are two types of glaucoma, primary open
    angle glaucoma, and angle-closure glaucoma.
    Primary open angle glaucoma is the more common of
    the two. The latter could entail an acute angle
    closure attack and the patient may need immediate
    help from an ophthalmologist for appropriate
    treatment including laser iridotomy. Primary open
    angle glaucoma is painless and develops gradually
    (is asymptomatic), hence the person does not
    perceive any changes in the vision in the early
    stage. The affected person realizes the change in
    vision only after glaucoma has brought about
    significant damage to the optic nerve.

  • Importance of Glaucoma Diagnosis
  • In India, almost 90 percent of those affected by
    the disease go undiagnosed. This gap in glaucoma
    diagnosis is alarming and early detection is
    crucial to prevent permanent blindness in
    patients. To detect any early signs of optic
    nerve damage due to open-angle glaucoma,
    ophthalmologists recommend regular eye exams to
    their patients. To be treated successfully,
    timely detection of the disease is critical.
  • In both, urban and rural India, awareness
    initiatives regarding risk factors and the
    importance of regular eye check-ups are the need
    of the hour. In rural regions, there is a
    scarcity of both awareness and qualified
    ophthalmologists who can detect and treat the
    condition. In the preferred practice patterns of
    the American Academy of Ophthalmology,
    comprehensive eye examinations are recommended
    for regular patients to rule out glaucoma after
    the age of 40 years. However, this does not
    happen as a routine in India. Hence awareness
    about glaucoma and the need for comprehensive
    checkup needs to be emphasized.

  • Diagnosis and Treatment Techniques
  • General ophthalmologists or sub-specialists carry
    out diagnoses for glaucoma in India. Treatment is
    customized and may vary based on the type of
    glaucoma.
  • To detect glaucoma, eye-specialists carry out a
    series of tests to check the extent of the
    damage. The three screening tests comprise of the
    intraocular pressure, gonioscopy (a test to check
    the fluid drainage channels in the eye),
    examination of the optic nerve (nerve that
    connects the eye to the brain), and a test to
    check for non-seeing areas (scotomas) in the
    patients field of vision. Once diagnosed,
    open-angle glaucoma is treated with eye drops to
    alleviate the pressure in the eye. The patient
    must diligently take the eye drops life long as
    prescribed by the treating doctor. If the eye
    drops do not help to control glaucoma, the
    specialist may suggest alternatives like laser or
    surgery.
  • Individuals interested in understanding the
    diagnosis, treatment, and management of glaucoma
    can sign up for our ICO certified course. It
    covers topics including pathophysiology of
    glaucoma, intraocular pressure, gonioscopy, disc
    evaluation, visual field testing, role of
    imaging, medical management and surgical options
    and management.
