Macular Degeneration

Macular Degeneration

Macular degeneration is the deterioration of the macula. The macula is a small central area in the retina which allows us to see small fine objects clearly.

Macular-Degeneration-1

 

Types of macular degeneration:

Age-related macular degeneration (AMD)

AMD affects adults above the age of 55 and the one of the leading cause of irreversible blindness in the world. The causes of AMD range from genetic factors to environmental factors like increasing age and smoking.

Types of AMD

Early (Dry) AMD

Yellow deposits called drusens are situated at the centre of the eye and can causes significant visual impairment depending on location.

Macular-Degeneration-2

Symptoms of Dry AMD

  • Blurring of vision
  • Straight lines looking wavy or distorted

Macular-Degeneration-3-1

  • Dark spot in the centre of your vision

Macular-Degeneration-4

Preventive therapy to reduce the risk of the progression to late AMD

(Please note that these methods do not cure AMD)

  • Oral vitamins (C and E) and antioxidants (Zinc, Copper)
  • Cessation of smoking
  • Healthy lifestyle with balanced diet and regular exercise
  • Regular Amsler grid monitoring is vital for those with early AMD, with detection of any distortions; call the clinic to schedule for an appointment.

Late (Wet) AMD

Diabetic-5

It is classified as the development of abnormal new blood vessels underneath the retina; these vessels leak blood or fluid, affecting the central vision.

 

Evaluation

  • Amsler grid is used to detect for any wavy or distortion of straight lines and for any loss of central vision

Macular-Degeneration-6

  • Disc macula photography to determine for the presence of drusens or any bleeding in the eye

Macular-Degeneration-8

  • Optical Coherence Tomography to scan the layers of the retina

Macular-Degeneration-7

  • Fluorescein Angiography – to detect the areas of leakage by having a dye called fluorescein injected into the blood stream

Macular-Degeneration-10

Treatment  

  • Intravitreal injections (Lucentis/ Avastin) are injections of anti-VEGF into the vitreous cavity of the eyeball to prevent the growth of these abnormal new blood vessels.
  • Retinal Laser Photocoagulation

Photodynamic Therapy (PDT) is carried out with a light sensitive drug (verteporfin) and low energy laser to slow down or prevent blood vessels from leaking.

These treatments may help preserve your remaining vision; however, it will not restore your vision back to normal. Low vision aids are available to assist day-to-day tasks.

 

Myopic Macular degeneration

It is characterized by the progressive increase in the eyeball length with the thinning and degeneration of the macula.

The risk of myopic macular degeneration is having more than 600 degrees of short-sightedness and axial length of more than 26 mm. Due to the degenerative changes of the macula, one might have risks of retinal tears and detachment which can lead to rapid loss of vision, cataracts, increased risk of open angle glaucoma.

Macular-Degeneration-9

Symptoms

  • Blurring of vision
  • Dark spot in the centre of your vision
  • Distortion in one’s vision
