New methods for the early diagnosis of the retina and optic nerve diseases

The future for the early diagnosis of diseases of the retina and optic nerve

Vision Engineering Italy is engaged in the development of automated methods for diagnosis of diseases of the retina based analysis of images acquired with ophthalmoscopes to adaptive optics.

Adaptive Optics Retinal Imaging

Adaptive optics in ophthalmology

The adaptive optics is a technique originally developed in astronomy, in order to reduce the blurring of images of terrestrial telescopes caused by atmospheric turbulence and better see the stars and planets away. The first prototype of ophthalmoscope to adaptive optics has been designed in optical laboratories of the vision at the University of Rochester (USA) in 1996.

Each cell has a diameter of a few micrometers (1 micrometer = 1 thousand of a millimeter). Thanks to adaptive optics technology, the early diagnosis of retinal diseases will be soon possible. The technology has the potential to save the sight of millions of people.

How does the adaptive optics work

Adaptive optics is a technology that correct for the ocular aberrations. Current ophthalmic diagnostic tools, such as OCT and scanning laser ophthalmoscopy, cannot resolve the microstructures of the retina and optic nerve. Adaptive optics ophthalmoscopy provides a spatial resolution 6 times higher than the best tools on the market today. It can resolve non-invasively the individual microstructures of the eye, such as the photoreceptors, capillaries and nerve fibers. The new technology will provide a powerful tool for early diagnosis and accurate treatment of neuro-retinal diseases. Millions of people around the world will benefit from the introduction of the technology of adaptive optics soon.

Our project

The staff of Vision Engineering Italy srl is engaged in the development of the technology of adaptive optics for the early diagnosis of diseases of the retina from 2002. The experience gained in these years represents the strength of the staff that works with the most important research centers in the world with the sole objective of advancing this technology toward clinical application.

Considering that today, in many cases, the retinal and optic nerve pathologies are diagnosed only after the appearance of retinal damage significant and irreversible, early diagnosis may represent the first step to cure early tissue damage and preserve sight.

All this entails the need to develop instruments and methods sensitive to specific changes, such as the loss of photoreceptors. The increase in contrast and resolution power offered by adaptive optics are capable of achieving this purpose.
