MAIA (Macular Integrity Assessment)

MAIA is the latest technology in assessing the integrity of the macular function. The macula is the central part of the retina, and it is in charge of the central vision: the one that allows us to read and provides us with colour vision, contrast and the finest details. It is one of the most relevant structures of the eye. That is the reason why it is important to boast cutting-edge technology to assess the macular function in a way that is non invasive, detailed and precise.

When measuring visual acuity at the doctor’s office, it is not possible to assess the total extension of the functional impairment that maculopathies present (the most common are: Age-related Macula Degeneration or AMD, and its variation Polypoidal Choroidal Vasculopathy or PCV, Diabetic Macular Edema, and Central Serous Chorioretinopathy). MAIA allows state-of-the-art Confocal Microperimetry. It analyses the functional and structural aspects of the macula. Basically, it is a non invasive technique that carries out a macular visual field. It is performed on one eye at a time and it does not require a dilated eye. It combines the shooting of imagines in the dilated eye exam with Scanning Laser Ophthalmoscopy, a system of retinal sensitivity mapping, and fixation analysis on the part of the patient. This last element presents a great advantage since it allows tracking the patient’s fixation activity while carrying out the visual field. In this way, it eliminates mistakes that are caused by fixation losses. This ensures the correlation between the results of the microperimetry, and the subjective perception of visual quality. In turn, this device presents different assessment options that use different strategies according to the pathology.

Microperimetry is a key tool to:

  • Monitor the progression of retinal pathologies.
  • Plan the treatment.
  • Assess the macular function before a cataract surgery.
  • Determine the fixation characteristics before a laser treatment.
  • Assess vision loss patients due to undetermined causes.
  • Educate the patient on their capacity of eccentric vision.
  • Detect macular pathologies.
  • The rehabilitation of low and eccentric vision patient

Microperimetry indications include:

  • Age-related Macular Degeneration.
  • Diabetic Macular Edema and Diabetic Retinopathy.
  • Epiretinal Membrane or Macular Pucker.
  • Macular Hole.
  • Central Serous Chorioretinopathy.
  • Hereditary degenerative diseases such as the Stargardt Disease, Choroideremia and Pigmentary Retinosis.
  • Retinal Vascular Diseases such as Central Retinal Vein Occlusion.
  • Macular Telangiectasia.

It is due to all these characteristics that Microperimetry is considered an extremely useful tool to monitor the different retinal pathologies that affect the macular area by means of a precise methodology that is non invasive and does not require a dilated eye.
