In glaucoma patients, reading difficulties may inspire e-reader apps

reading difficulties in glaucoma patients reading difficulties in patients with glaucoma can inspire the development of electronic reading applications. Research has shown that patients with glaucoma read slower when read in silence for longer periods of time. Your reading speed is more likely to decrease over time due to fatigue reading.

Pradeep Ramulu study author suggests that specific applications for electronic readers can help patients with glaucoma maintain their reading speed. He explained, “Right now, so many products are available for presenting reading material in a variety of formats. If you could determine the optimal format for reading in the context of glaucoma, it would be easy to create an application for submit text in this way as part of a commercial device like an iPad or Kindle. “

a group with bilateral glaucoma visual field and the other was the control group –

The study involved two groups. Both groups were evaluated by two tests of reading aloud (IREST and MNRead), a test of sustained silent reading during a period of 30 minutes, and an assessment of understanding for the materials sustained silent reading.

The results showed reading comprehension was lower in the glaucoma group compared with the control. Ramulu added.. “The ultimate goal is to be able to rehabilitate people with reading difficulties due to glaucoma Our group and others are exploring possible reasons behind these disorders, including disruption of the tear film and abnormal eye movements The understanding of why people with glaucoma read slower and show fatigue reading pave the way for resolving these difficulties reading. ”

Patients with glaucoma read less and have a lower reading ability: Study

In a study of 63 patients with glaucoma and 59 control patients with a diagnosis of suspected glaucoma complete 10 reading activities for low vision evaluation. Participants were evaluated with oral questionnaires, which were analyzed with the results of the reading activity.


Patients with glaucoma have a lower reading ability compared to controls, which was associated with a greater loss of visual field. They also reported greater difficulty in reading all activities except the puzzles.

Researchers concluded that patients with glaucoma have a lower reading ability and the lowest participation, especially for tasks that require prolonged reading.

The authors noted, “While reading is a common complaint among patients with glaucoma, only a small percentage of patients with glaucoma reference to rehabilitation services is made. One of the barriers to references may be the that doctors can not see how glaucoma patients who require the services of visual rehabilitation, as more often refer patients deficient central vision. An additional referral barrier may be that patients with glaucoma are often expressed serious reading difficulties to the extent that the reading would be impossible Finally, rehabilitation services, including efforts to allow reading, mainly adapted to serve patients with loss of central vision. – . not those with visual field loss “

The authors concluded that “further work is necessary to define the best methods to allow reading in glaucoma patients, perhaps by creating adequate lighting to optimize contrast and reduce glare, correction of eye movements abnormal, the use of visual aids to enlarge the text and / or teaching strategies to mitigate fatigue. “
