Glaucoma Study Could Inspire E-Reader Apps: New Findings Show Silent Reading Difficulties in Glaucoma Patients

12.12.2012
Better strategies are needed to help glaucoma patients cope with difficulty reading. According to a new scientific study published in Investigative Ophthalmology & Visual Science, adults with glaucoma read slower when reading silently for long periods of time and are more likely to have their reading speed decrease over time, possibly a result of reading fatigue.

Technological solutions such as e-readers – and the many apps being created for them – could help. “Right now, so many products are available for presenting reading material in a variety of formats,” says author Pradeep Ramulu MD, PhD, of The Wilmer Eye Institute, Johns Hopkins Hospital. “If the optimal format for reading in the context of glaucoma could be determined, it would be easy to create an application to present text in this manner as part of a commercial device such as an iPad or Kindle.”

The recently published article, “Difficulty with Out-loud and Silent Reading in Glaucoma,” reports that the sustained silent reading speed for glaucoma patients with bilateral Visual Field (VF) loss is significantly less than the speed associated with out-loud reading.

The study was conducted with two groups from the Wilmer Eye Institute: patients with bilateral VF loss from glaucoma and the control group made up of glaucoma suspect patients. Both groups were evaluated using two out-loud reading tests (IReST and MNRead), a sustained silent reading test over a 30-minute period and a comprehension evaluation corresponding to the sustained silent reading material. On the IReST evaluation, those with glaucoma read 147 vs. the control group 163 words per minute (wpm); on the MNRead, those with glaucoma read 172 vs. the control group 186 wpm; and on the sustained silent reading test, those with glaucoma read 179 vs. the control group 218 wpm — a 16 percent slower reading speed.

The results also showed that reading comprehension was lower in the glaucoma group than the control group. Though this finding fell just outside the cutoff for statistical significance, the research team suggests further studies be conducted to investigate whether visual defects or coexisting cognitive defects are the cause.

“The ultimate goal is to be able to rehabilitate individuals with reading difficulties due to glaucoma,” says Ramulu. “Our group and others are exploring possible reasons behind these impairments, including disruption of the tear film and aberrant eye movements. Understanding why people with glaucoma read slower and show reading fatigue will pave the way for solving these reading difficulties.”

The ARVO peer-reviewed journal Investigative Ophthalmology & Visual Science (IOVS) publishes results from original hypothesis-based clinical and laboratory research studies, as well as Reviews, Perspectives, and Special Issues. IOVS 2009 Impact Factor ranks No. 4 out of 45 among ophthalmology journals. The journal is online-only and articles are published daily.

The Association for Research in Vision and Ophthalmology (ARVO) is the largest eye and vision research organization in the world. Members include more than 12,500 eye and vision researchers from over 80 countries. ARVO encourages and assists research, training, publication and knowledge-sharing in vision and ophthalmology.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
