    Contrast sensitivity device exposes vision limitations of reattachment patients

    Despite achieving a good letter visual acuity, patients with macula-off rhegmatogenous retinal detachments can be frustrated with their vision following reattachment surgery.

    This scenario also is frustrating for physicians and it begs the questions regarding how this visual dysfunction can be better assessed and what functional measures can be used to demonstrate significant improvement with new therapeutics? A new device under development might answer these questions.

    “While we are all familiar with letter visual acuity, it doesn’t always tell the full story about a patient’s quality of vision,” John Miller, MD, said. “Surgeons can obtain anatomic success and visual acuity success after reattachment of retinal detachments, but patients remain frustrated with their vision.”

    A new platform, the Sentio Platform (Adaptive Sensory Technology), might provide physicians better insights into what patients are experiencing. The device uses a testing algorithm that determines the contrast sensitivity after a retinal detachment has been repaired.

    This platform, in the form of a handheld tablet described as a novel contrast sensitivity testing device, was evaluated for its ability to perform quick contrast sensitivity function testing of patients in relation to their visual activities.
