Robots have been around the OR for a while, but none look much like C3PO or R2D2. They do help in delicate procedures, lending the precise nature of a robotic arm with an exactness that is hard to duplicate in a human.
The robots are coming to the delicate world of eye surgery as well. A couple of years ago, tweed-clad researchers at the University of Oxford began clinical trials for the PRECEYES Surgical system.
In the robot-assisted surgery, the (human) surgeon takes charge of PRECEYES and controls the mobile arm with a joystick. You can swap out various instruments on the arm, and it eliminates the slight tremors that plague even the most steady-handed of humans.
The surgeon slips the robot through an incision less than 1mm in diameter
The trial enlisted 12 patients that each needed a membrane removed from their retina. Six received traditional surgery, and the other half were robot-assisted.
In the robotic procedure, the surgeon slips the robot through an incision less than 1 mm in diameter. It separates the membrane from the retina, then removes the membrane from the eye, and exits through the same hole. In the surgeries conducted without the robot, the surgeon manually uses microsurgical instruments while peering through an OR microscope.
All 12 surgeries, both robot-assisted and traditionally human, were successful. Check out more details in Nature Biomedical Engineering.
Could the key to detecting Alzheimerâ€™s disease before it savages the brain be in the eyes? A recent study published in in JAMA Ophthalmology says itâ€™s a possibility.
In the study, doctors examined the eyes of older people who had no signs of dementia and found abnormalities in the retinas of those who also had biomarkers for the disease, which can predict whether a person who has normal cognition now will go on to develop Alzheimerâ€™s.
Thereâ€™s a large body of literature showing structural changes in the retina and the optic nerve in patients with established Alzheimerâ€™s disease so researchers could look for pathologic changes in the brain that parallel the changes in the eye.
The study involved 30 people who showed no signs of dementia, but 14 of them were diagnosed with preclinical Alzheimerâ€™s based on their positive biomarkers, as measured by a PET scan or cerebral spinal fluid testing, or both.
The researchers examined each personâ€™s retina and optic nerve using optical coherence tomographic angiography (OCTA), It turned out an area in the center of the retina without any blood vessels was much larger in the participants who had the biomarkers for Alzheimerâ€™s than those who didnâ€™t. It was also thinner.
Of course, more research is needed but this could be a big step forward in finding and treating Alzheimerâ€™s as early as possible.

Most doctors stick their necks out to help their patients…in some cases, literally. But the result is neck and back pain thatâ€™s sometimes debilitating. In a study by the American Academy of Ophthalmology and in similar studies conducted in the U.K. nearly 73% of eye doctors reported pain in the neck, back or both.
Your slit lamp, the major culprit, as it is usually positioned on the exam table, requires you to lean toward the instrument, and extend the neck out of alignment with the spine. This repetitive motion can happen 40- to 60-times a day in an average practice. Over time, this posture causes serious neck and back problems that can lead to excessive pain, surgery or early retirement. A few simple precautions can help.
Move the Slit Lamp
To alleviate the strain, modify the slit lamp table to move closer to you than to the patient. While the patient may be uncomfortable for a few minutes each year, the doctor can do the exam with less pain day after day.
Although the waiting room may be full of patients, spend the extra few seconds to properly position the patient to eliminate unnecessary craning or hunching.
Stretch Several times a day
Take a few minutes and do neck and back stretches. See the Mayo Clinic videos for easy stretches you can do anywhere.
Give Your Slit Lamp an Adjustment
Manufacturers also offer some pain-saving solutions, like an inclined adaptor that raises the viewing angle and keeps your head in a fatigue-free position. For more information, contact Bell Ophthalmic at 800.255.5929 or email us!
If youâ€™re ready for a new OCT, Topcon has you covered.
The 3D OCT-1 Maestro System features a high-resolution color non-mydriatic retinal camera combined with the latest Spectral Domain OCT technology. A 12mm x 9mm scan along with automated segmentation provides measurement and topographical maps of the optic nerve and retina in one scan. The Maestro is a fully automated, affordable, and all-in-one compact system that fits well into small office settings.
Or if youâ€™re ready to move up to the next level, the Topcon DRI OCT Triton is just the ticket. This multi-modal â€śSwept Sourceâ€ť OCT is equipped with a non-mydriatic color fundus camera. The Triton Plus model includes modes for both FA and FAF imaging. The Triton provides uniform scanning sensitivity at 100,000 A-scans per second with a 1050nm wavelength source resulting in stunningly clear and detailed images. The superior light source allows imaging to the deepest layers of the retina as well as through opacities such as cataract and hemorrhage. Data management with ImageNet 6 provides for efficient data collection in a shorter period of time, improving workflow and saving time!
