Microperimetry 25/03/2013

Microperimetry is one of the most specific examinations to determine defects in central vision and the extent of damage produced by certain illnesses such as age-related macular degeneration, diabetic retinopathy, diabetic macular oedema and central serous retinopathy.

Microperimetry is a non-invasive technique that measures the macular visual field. It is carried out first on one eye and then on the other and does not require the eyes to be dilated. In reviews**, it is clear that microperimetry is, today, a novel instrument for assessing the visual performance of a significant number of retinal alterations. Microperimetry is considered to be the ideal instrument for this kind of examination and its advantages are related to its capacity to carry out an automatic tracking system that guarantees fast, accurate analysis of the retina's sensitivity and the location and stability of adhesion. Its results, which have been related in several studies with those provided by optical coherence tomography in retina disorders, have statistically significant correlations with the latter, enabling a comprehensive assessment of patients' visual function in terms of both morphological and functional changes.
