What does ANDREW DEEMER research?

Dr. Deemer studies how technology and interventions can assist people with low vision and visual impairments, focusing on strategies to enhance their reading abilities and overall independence. He evaluates different approaches, such as head-mounted devices, handheld magnifiers, and telehealth options, to determine their effectiveness in improving daily life for those with vision problems. Additionally, he investigates the impact of external factors like the COVID-19 pandemic on traumatic injuries and outcomes across different age groups, from adults to children.

Key findings

  • Self-management interventions for adults with visual impairments showed a negligible impact on health-related quality of life with a standardized mean difference of -0.09.
  • In a study of 88 participants, both head-mounted magnification methods significantly improved reading abilities for individuals with low vision.
  • Participants in a study on telehealth training for magnifying devices improved reading ability by 0.61 logits in the first month and 0.44 logits in subsequent months, with no significant difference compared to in-person training.
  • Handheld optical illuminated magnifiers increased reading speed by an average of 14 words per minute after one month, particularly benefiting those who started with slower reading speeds.
  • During the COVID-19 pandemic, adult traumatic orthopedic injuries dropped by 26%, while mortality rates increased from 4% to 6.1%.

Publications in plain English

Self-management interventions for quality of life in adults with visual impairment.

2025

The Cochrane database of systematic reviews

Malkin A, Deemer A, Contreras M, Edmonds H, Quan AC +4 more

Plain English
This study looked at programs designed to help adults with visual impairments manage their condition and improve their quality of life. Researchers analyzed 20 different studies involving over 3,100 participants and found that these self-management interventions had little to no impact on improving overall health-related quality of life or vision-related quality of life. For instance, the change in health-related quality of life scores was very small, with a standardized mean difference of just -0.09, indicating the intervention may not lead to significant improvements. Who this helps: This research is relevant for older adults with visual impairments and healthcare professionals working with them.

Outcomes of Telerehabilitation Versus In-Office Training With Magnification Devices for Low Vision: A Randomized Controlled Trial.

2024

Translational vision science & technology

Bittner AK, Kaminski JE, Yoshinaga PD, Shepherd JD, Chan TL +7 more

Plain English
This study investigated whether training for new magnifying devices is more effective when done remotely through telerehabilitation or in-person at an office for individuals with low vision. Researchers found that, on average, participants improved their reading ability by 0.61 logits in the first month after training and by an additional 0.44 logits in the following months, with no significant difference between those who received telerehabilitation and those who trained in the office. This is important because it shows that remote training can be just as effective as in-person visits, providing more flexible options for improving reading skills for those with visual impairments. Who this helps: This helps patients with low vision who may benefit from more convenient training options.

Value of Handheld Optical Illuminated Magnifiers for Sustained Silent Reading by Visually Impaired Adults.

2023

Optometry and vision science : official publication of the American Academy of Optometry

Kaminski JE, Yoshinaga PD, Chun MW, Yu M, Shepherd JD +4 more

Plain English
This study looked at how handheld, illuminated magnifiers can help visually impaired adults read longer texts like books and magazines. After using the magnifiers for a month, participants improved their reading speed by an average of 14 words per minute, with those who read slower at the start seeing the most significant gains. This is important because it shows that these magnifiers can not only assist with short readings but can also help people read more and faster over longer periods, enhancing their reading experience and independence. Who this helps: Visually impaired adults looking to improve their reading skills.

Diltiazem Does Not Prevent Postoperative Atrial Fibrillation After Thoracoscopic Lobectomy.

2021

Innovations (Philadelphia, Pa.)

Lederer MR, Deemer A, Liongson FA, Roma N, Lee CT +2 more

Plain English
This study looked at whether the medication diltiazem could help prevent a common heart rhythm problem called postoperative atrial fibrillation (POAF) in patients who had minimally invasive lung surgery (thoracoscopic lobectomy). Researchers found that diltiazem did not lower the rates of POAF, which affected about 12.5% of the patients, regardless of whether they received the drug or not. Specifically, older patients (ages 65-74 and 75 and older) were more likely to develop POAF, with odds increasing by about 2.88 and 2.62 times, respectively, compared to those under 65. Who this helps: This information is important for doctors treating older patients undergoing lung surgery, as it clarifies that diltiazem is not effective in preventing POAF.
