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:
Microperimetry indications include:
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.
