"We have 86 volunteer trainers, all with central vision loss
themselves, who have trained more than 310 people in their own communities, and our waiting list of nearly 1,200 people grows every day.
Systematic scanning strategies should be taught to all individuals with central vision loss
and those with peripheral vision loss, so as to allow objects to be located faster and more efficiently.
The team speculates that, by using their peripheral vision to compensate for their central vision loss
, patients are contributing to the cortical thickening seen in the study.
In this article, I describe the Macular Mapping Test (MMT) and illustrate with case reports how it can be used in clinical practice to assist in the assessment and rehabilitation of patients with central vision loss
With projections indicating that the number of cases of late AMD will reach 679,000 by 2020, a significant number of patients will be facing the news that they are developing signs of macular disease or will already be living with central vision loss
Measuring the effectiveness of bioptic telescopes for persons with central vision loss

Instead of a rapid deterioration in vision, ending with profound central vision loss
, most patients receiving anti-VEGF treatment are able to maintain their vision and sometimes some of their lost vision is restored.
There is limited (Level 2b) evidence, based on one good-quality study (Szlyk et al., 1993) and one fair-quality study (Fishman, Anderson, Stinson, & Haque, 1981), that younger persons with central or peripheral vision loss exhibit more lane-boundary crossings and longer braking responses relative to age-matched individuals with no vision loss, but drivers with RP have reported significantly more accidents than have those with central vision loss
. Fishman et al.
This develops into geographic atrophy of the RPE and choriocapillaris, causing severe central vision loss
. In OCT, different types of drusen show different morphological structures and light scattering properties.
First, many state and private service agencies required recipients to be legally blind to qualify for Medicare-funded rehabilitation, whereas those with gradually progressing central vision loss
from AMD require vision rehabilitation training long before their vision deteriorates enough to qualify as legal blindness.
The chairman of the scientific committee of the Royal College of Ophthalmologists, Winfried Amoaku, added: "Research studies around the world have shown that eccentric viewing, though a relatively new phenomenon, can help some patients with central vision loss
to cope with everyday tasks such as identifying coins while out shopping, watching television and reading the time.
