Scleral Indentation Instruments for Reducing Eye Exam Discomfort
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial aims to determine which of three instruments used during an eye exam causes the least discomfort for patients. The exam involves checking the retina at the back of the eye, which can be uncomfortable. Participants will join one of three groups, each comparing different tools for this exam, including scleral indentation, a technique used to better view the retina. Individuals who have experienced issues from a posterior vitreous detachment—a common eye condition where the gel in the eye pulls away from the retina—might be a good fit. As an unphased trial, this study offers participants the chance to contribute to improving patient comfort during eye exams.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications, but it excludes those who are currently using pain medications.
What prior data suggests that these scleral indentation instruments are safe for reducing eye exam discomfort?
Previous studies have commonly used tools like the Schocket and Josephberg-Besser in eye exams. These tools help doctors examine the retina, the back part of the eye, by gently pressing on the sclera, the white part of the eye. Research has shown that patients generally tolerate these instruments well.
Some reports indicate that patients might feel slight discomfort during the exam, but serious side effects are rare. A cotton-tip applicator, also used for similar exams, is considered safe, though it might cause slight irritation. Overall, the long-term use of these instruments in eye care suggests they are safe for most patients.12345Why are researchers excited about this trial?
Researchers are excited about this trial because it explores new tools to make eye exams more comfortable. Unlike traditional methods, which often rely on cotton tip applicators, this trial compares different scleral depressors—specifically the Schocket and Josephberg-Besser depressors. These instruments potentially offer a more precise and less uncomfortable way to examine the eye. The trial aims to find out if these tools can reduce discomfort while still providing reliable exam results, which could lead to a better experience for patients during eye exams.
What evidence suggests that these scleral indentation instruments are effective for reducing eye exam discomfort?
Research has shown that using different tools during eye exams can enhance comfort. In this trial, participants will experience various tools in separate treatment arms. Some arms will use the Schocket scleral depressor, which has a rounded shape that applies gentle pressure on the eye, potentially improving comfort. Other arms will use the Josephberg-Besser scleral depressor, which is particularly beneficial for individuals with tight eyelids, possibly reducing discomfort. Additional arms will employ the cotton-tip applicator, a simple, disposable tool that often causes less pain during procedures like pulling back the eyelid. Each tool offers unique benefits that can contribute to a more comfortable exam.26789
Are You a Good Fit for This Trial?
This trial is for individuals who need a retinal examination, which involves pressing on the eye's surface (sclera) to view the retina. Participants must be comfortable with random assignment to have one of their eyes tested with either a Schocket scleral depressor, Josephberg-Besser scleral depressor, or cotton tip applicator.Inclusion Criteria
