Outcome measures
Primary outcome
Reading acuity and reading speed in words per minute and number of characters
per minute.
(1) Validation of different reading cards
(2) Comparing usefulness of different reading cards
(3) To examine the relationship between patient characteristics and reading
performance on the different reading cards
De patient characteristics that will be examined are
- Distance visual acuity
- Eye disease
- Central visual field
- Contrast sensitivity
- Glare
- Age
- Gender
- Education
- Cognition
- Health status
Secondary outcome
- Depression (Center for Epidemiological Studies * Depression scale: CES-D)
- Co-morbidity (chronic disease questionnaire)
- Vision related quality of life (Low Vision Quality Of Life questionnaire:
LVQOL)
- Rehabilitation needs (Dutch ICF Activity Inventory: D-AI)
Background summary
One of the largest problems for people with visual disabilities is near work
and especially reading. These reading problems have a negative impact on social
and independent functioning. A good chart for measuring the near acuity
provides detailed information about visual impairment and helps to evaluate the
functional vision. It is also important that diffrente study's of the
effectiveness of various optical devices, which often uses a readingcard, can
be compared with each other. There are currently different readingcards used in
Dutch practice and in several studies. This makes it difficult to compare
mutual research.
Two common readingcards in Dutch ophthalmic practice are the 'LEO-read card'
and 'de Nederlanders'. The first publication of the LEO-reading card was in the
conference proceedings of Vision 1996 in Madrid. The LEO-read card has since
than been used by all institutions for the rehabilitation of people with visual
impairment and ophthalmic clinics in various ophthalmology practice. The
reading card 'de Nederlanders' is more than 40 years old, exact publication
date or other additional information cannot be found.
Although these charts are respectively 15 and more than 40 years of age, there
has not yet been done a thorough and validating comparative research. At this
moment, research on readingcards suitable for scientific research in various
languages is and has been done. An example is the Radner reading card (Maaijwee
et al, 2008) and the IReST II (Hahn et al, 2006).
The Dutch Reading Test Study will focus on validating and comparing the above
named reading cards in visually impaired patients with different eye
conditions.
Study objective
In this study we investigate the reliability, validity and feasibility of
different reading cards and the relationship within and between patients with
different eye conditions.
Study design
This research involves an observational study on the validity and reliability
of different reading cards.
Study burden and risks
No risk is to be expected from this study.
