New type of laser treatment has the potential to slow progression of age-related macular degeneration – a major cause of vision loss – without damaging the retina.
This was the conclusion of a study from the University of Melbourne in Australia, published in The FASEB Journal.
Erica Fletcher, an associate professor in Melbourne’s Department of Anatomy and Neuroscience, and colleagues examined the effectiveness of a new low-impact, low-energy, laser treatment for patients with early age-related macular degeneration (AMD).
They found that, unlike other laser treatments, the “nanosecond laser” they tested did not damage the retina – the tissue at the back of the eye that contains light-detecting cells.
Prof. Fletcher says theirs is the first study to describe how the new laser treatment may improve eye health in patients with AMD.
AMD is a painless eye condition that gradually results in loss of central vision. According to the Centers for Disease Control and Prevention (CDC), it is the leading cause of permanent impairment of fine or close-up vision – for example as needed for reading – among people aged 65 years and older.
Estimates suggest about 1.8 million Americans aged 40 and over have AMD and another 7.3 million are at risk of developing it.
In Australia, where the study took place, AMD is responsible for 48% of severe vision loss, with an estimated 17,700 new cases each year.

New laser treatment reduced drusen and thickness of Bruch’s membrane

Examination of the back of the eye in the early stages of AMD reveals the presence of small fatty deposits called drusen, and a thickening of a thin layer of tissue called Bruch’s membrane. As these features worsen, they slowly destroy the central part of the retina.
The study shows that the nanosecond laser can reduce drusen and thin the Bruch’s membrane without damaging the structure of the retina…..
