Face-Down Posture-Related Pain after Vitrectomy: Clinical Characteristics and Temporal Distribution
This prospective study of 199 vitrectomy patients reveals that posture-related musculoskeletal pain is highly prevalent and a major barrier to face-down positioning adherence within the first 24 hours post-surgery, with pain intensity and adherence levels varying significantly by time of day and specific anatomical location, thereby underscoring the need for targeted, time-specific nursing interventions to improve patient compliance and outcomes.

Imagine your eyes are like a delicate camera, and sometimes, the lens or the film inside gets damaged. To fix these problems, eye surgeons perform a delicate operation called a vitrectomy, where they remove the jelly-like substance inside the eye and replace it with a special "plug"—either a gas bubble or a silicone oil—to hold the back of the eye in place while it heals. Think of this plug like a buoyant life preserver floating inside a pool; it needs to press against a specific spot on the wall of the pool to keep a tear sealed shut. To make sure this "life preserver" stays exactly where the surgeon wants it, patients have to lie face-down for hours or even days. It's a bit like holding a yoga pose that nobody enjoys, but it's the only way to make sure the eye heals correctly. However, holding this position is tough on the body, causing aches and pains that can make people want to give up and sit up, which would ruin the repair. The big question is: when does this pain hit the hardest, and does it make people break the rules?
A team of researchers from the Joint Shantou International Eye Center decided to investigate this "face-down struggle" by watching 199 patients closely for the first 24 hours after their eye surgery. They wanted to map out exactly when and where the body started to scream "ouch," and how that pain affected the patients' ability to stay in the correct position. They treated the 24-hour period like a timeline, checking in every few hours to see if patients were still face-down and how much pain they were feeling in different body parts like the neck, shoulders, arms, and back.
Here is what they found: more than half of the patients—specifically 62.3%—experienced muscle pain related to the position within that first day. The biggest culprit? Muscle soreness. In fact, muscle soreness was the number one reason patients failed to keep their face-down posture, accounting for 36.2% of the times they slipped up. The second biggest reason was simply that the position felt too long to hold (22.6%), followed by just finding it hard to get used to the pose (17.1%).
The researchers also discovered that pain and compliance (staying in position) have a very specific rhythm, almost like a tide that goes in and out. If you look at the clock, the patients were most likely to break their pose during the early morning hours (between midnight and 6 AM), with only about 43.7% of them staying face-down. They did a bit better in the afternoon and evening. But if you look at the timeline of the surgery itself, the patients started strong, with 68.8% staying in position during the first 6 hours. However, as time marched on, their ability to hold the pose dropped steadily, falling to just 46.4% by the time 18 to 24 hours had passed.
When it came to where the pain hurt, the story got even more interesting. The pain in the shoulders, neck, and back was a constant companion; it was there from the start and didn't really change much throughout the day. However, the pain in the arms and chest had a dramatic peak. These specific pains were quiet at first but then exploded in intensity between 12 and 18 hours after surgery. The researchers suggest this happens because, after holding the pose for a while, the muscles in the arms and chest get exhausted from supporting the head, or the chest gets compressed if the patient is lying flat.
So, what does this mean for the future? The paper suggests that nurses and doctors shouldn't treat the whole day the same way. Instead of a one-size-fits-all approach, they should be extra vigilant during the "danger zones": the early morning hours when patients are sleepy and the 12-to-18-hour window when arm and chest pain peaks. By offering help like massage, specific exercises, or better pillows right when the pain is about to hit its peak, doctors might be able to help patients stay in position longer, ensuring their eyes heal properly. The study didn't prove that these fixes will work yet, but it definitely points out exactly when the help is needed most.
