Diabetic Macular Edema (DME)
  • Definition of DME swelling of the retina in
    diabetes mellitus due to leaking of fluid from
    blood vessels within the macula1
  • Macular edema is common in diabetes with a
    lifetime risk of 101
  • The condition is closely associated with the
    degree of diabetic retinopathy
  • Clinically Significant Macular Edema (CSME), as
    defined by the Early Treatment Diabetic
    Retinopathy Study (ETDRS), includes any of the
    following findings2,3
  • Retinal thickening within 500 µm of the center of
    the fovea
  • Hard, yellow exudates within 500 µm of the center
    of the fovea with adjacent retinal thickening
  • At least 1 disc area of retinal thickening, any
    part of which is within 1 disc diameter of the
    center of the fovea

Glaucoma
  • Glaucoma represents a heterogeneous group of
    optic neuropathies and is estimated to affect 12
    million Indians it causes 12.8 per cent of the
    total blindness in the country and is considered
    to be the third most common cause of blindness in
    India
  • An Asian survey presented at the World
    Ophthalmology Congress in Hong Kong in July 2008
    revealed that between 2010 and 2020, India will
    be the worlds glaucoma capital.
  • Primary angle-closure glaucoma (PACG) is a major
    form of glaucoma in Asian countries. According to
    an Indian hospital-based data, PACG appears to be
    as prevalent as primary open-angle glaucoma
    (POAG), accounting for 45- 55 of primary
    glaucoma cases.

Asia. Journal of Glaucoma 2001 5 Suppl 1S7-S8
16
Glaucoma treatment
  • Since the disease is not curable early detection
    and prevention are the key focus areas, however,
    surgery and laser treatment do appear to be
    promising
  • Treatment includes - glaucoma surgeries
  • trabeculectomy - the procedure of choice
    particularly for secondary glaucomas.
  • Various new modalities - mini trab procedure ,non
    penetrating filtering procedure, trans ciliary
    filtering surgery in 2004, limbal filtering
    surgery in 2006 using a fugo plasma blade.
  • Newer glaucoma surgeries (non-penetrating) like
    deep sclerectomy, viscocanalostomy and
    trabeculectomy ab-externo have also shown
    promising results.

17
Glaucoma treatment - latest procedures
  • Cyclocryotherapy for ciliary body ablation helps
    reduce the eye pressure and alleviate pain.
  • Glaucoma implants have been used for patients who
    are not responding to maximal medical therapy or
    are failed glaucoma surgery or poor candidates
    for glaucoma surgery.
  • Selective Laser Trabeculoplasty (SLT)
  • Ciliary body diode laser cycloablation
  • NdYAG Laser peripheral iridotomy

18
Refractive errors
  • Refractive errors (myopia, hypermetropia,
    astigmatism, presbyopia) result in an unfocussed
    image falling on the retina.
  • Uncorrected refractive errors, which affect
    persons of all ages and ethnic groups, are the
    main cause of visual impairment.
  • There are estimated to be 153 million people with
    visual impairment due to uncorrected refractive
    errors, i.e. presenting visual acuity lt 6/18 in
    the better eye, excluding presbyopia.
  • Globally, uncorrected refractive errors are the
    main cause of visual impairment in children aged
    515 years. The prevalence of myopia
    (short-sightedness) is increasing dramatically
    among children, particularly in urban areas of
    South-East Asia.

19
Refractive vision correction
  • The most frequently used options for correcting
    refractive errors are
  • spectacles, the simplest, cheapest and most
    widely used method
  • contact lenses, which are not suitable for all
    patients or environments
  • corneal refractive surgery, which entails
    reshaping the cornea by laser.

20
Trends in refractive vision correction
  • The path to refractive corrections for myopia,
    hyperopia, presbiopia and astigmatism is pitted
    with technologically sound techniques
  • Broad range of options to treat each patients
    unique needs
  • LASIK, Laser-Assisted Sub-Epithelial Keratectomy
    (LASEK)
  • clear lens exchange (CLE),
  • phakic intraocular lenses (PIOL), and
  • conductive keratoplasty (CK)

21
Age Related Macular Degeneration (ARMD)
  • Age-related macular degeneration is the commonest
    cause of blindness in industrialized countries.
  • Age-related macular degeneration has two forms,
    wet and dry. In most populations, the dry
    form is the more frequent, but it is less likely
    to lead to severe bilateral visual loss.
  • Age-related macular degeneration is responsible
    for 8.7 of all blindness (3 million persons) due
    to eye diseases, ranging from close to 0 in
    sub-Saharan Africa to 50 in industrialized
    countries.
  • The number affected is expected to double by the
    year 2020 as a result of the ageing of the
    worlds population.

22
Upcoming trends in the treatment of ARMD
  • Photodynamic therapy (trade name Visudyne) uses a
    non-thermal (or cold) laser with an intravenous
    light-sensitive drug to seal and halt or slow the
    progression of abnormal retina blood vessels.
  • LASER photocoagulation is a procedure involving
    the application of a hot laser to seal and halt
    or slow the progression of abnormal blood vessels
  • New anti-vascular endothelial growth factor
    agents are being investigated, and more research
    is needed.
  • Surgical translocation of the macula and
    submacular surgery are indicated only for
    selected patients, as surgery requires highly
    experienced vitreo-retinal surgeons, and the
    results are not always favourable.

23
Cataract
  • The most recent estimates from WHO reveal that
    47.8 of global blindness is due to cataract
  • South Asia region which includes India, 51 of
    blindness is due to cataract
  • Approximately, nine million Indians are blind
    from cataract with another 1.8-3.8 million going
    blind from cataract every year.
  • Ophthalmologists and programme planners have been
    able to effectively increase cataract surgical
    output from a low of 1.2 million surgeries in
    1992 to a high of 4.8 million surgeries in 2006
    with intraocular lenses (IOLs) used in 90 per
    cent of cases

24
Reasons for decreasing in blindness prevalence
  • 25 decrease in blindness prevalence in India
    (WHO report)
  • This could be due to the increased cataract
    surgeries in the country
  • Due to factors
  • indigenous manufacturing of IOLs,
  • equipment and supplies for cataract surgery,
  • structured training programmes,
  • infrastructure development and
  • co-ordinated efforts by the Government and the
    international NGOs

The Right to Sight in India
  • India was the first country in the world to
    launch the National Programme for Control of
    Blindness in 1976 with the goal of reducing the
    prevalence of blindness.
  • Of the total estimated 45 million blind persons
    in the world, 7 million are in India.
  • Due to the large population base increased life
    expectancy, the no. of blind particularly due to
    age-related disorders like cataract, is expected
    to increase
  • Main causes of blindness in 50 population are
    cataract 62.6, refractive errors 19.7, corneal
    blindness 0.9, glaucoma 5.8, surgical
    complications 1.2, posterior segment disorders
