Brief Summary:
The goal of this clinical trial is to learn if Vibration Anesthesia Device works to reduce pain during retinal laser for diabetic retinopathy The main question it aims to answer is
Does the Vibration Anesthesia Device reduces the pain felt by patients during the laser treatment Researchers will compare the standard method no vibration device to the standard method with the Vibration Anesthesia Device to see if the device works to reduce discomfort during treatment
Eligible participants will have both eyes treated as required one eye with the device and the other one without Both the side that will be treated with the device in place and the first side to be treated will be decided by random sequence

Detailed Description:
Background
Panretinal photocoagulation PRP is a widely used laser treatment for proliferative diabetic retinopathy PDR However the associated ocular pain can make the procedure uncomfortable leading to increased treatment visits or missed appointments This pain is multifactorial and can be exacerbated by factors such as anxiety and hypervigilance Traditional pain management techniques such as regional anesthesia are effective but invasive and carry potential complications Oral medications have largely proven ineffective in alleviating PRP-related pain
The Gate-Control Theory of pain posits that non-noxious stimuli can inhibit pain signals by activating A-β fibers effectively closing the gate to pain transmission through A-δ and C fibers The most relatable example is the mother rubbing a childs knee after an impact injury in the affected region Transcutaneous electrical nerve stimulation TENS which utilizes the Gate-Control Theory of pain has been shown to reduce ocular pain during PRP However its use raises practical concerns including the need to carefully adjust pulse width intensity and frequency for effective pain relief Additionally some patients may find the muscular contractions or paresthesia uncomfortable TENS is also contraindicated in individuals who are pregnant have epilepsy or have pacemakers Vibratory stimulation activates cutaneous mechanoreceptors to reduce pain during intramuscular and subcutaneous injections This technique is safer and less invasive than TENS and is therefore an ideal candidate for evaluating its effect in pain reduction during PRP This study has the potential for an innovative concept by utilizing a vibratory device integrated within the PRP machine headrest
Hypothesis
Vibratory stimulation is expected to reduce ocular pain during PRP by activating cutaneous mechanoreceptors and inhibiting pain transmission as suggested by the Gate-Control Theory Its non-invasive nature makes it a practical alternative to traditional pain management methods potentially enhancing patient comfort during the procedure
Objective
To evaluate the effectiveness of vibratory stimulation in reducing ocular pain during PRP treatments
Method
Subjects will be recruited at a single tertiary referral center Alberta Retina Consultants Edmonton Alberta Matriculation will be established upon obtainment of consent and patients will have the autonomy to withdraw from the study at any stage The enrollment period will be from October 2024 to March 2025 with a total of 50 patients
Laser settings will be tailored to each patient based on individual differences in pigmentation and tissue uptake The threshold for treatment will be determined by observing an opacified photothermic response For each patient one eye will be treated without vibratory stimulation while the contralateral eye will receive stimulation using the Blaine Labs Vibration Anesthesia Device The assignment of which eye receives which treatment will be randomized using Python programming ensuring a balanced allocation To minimize variability the time taken to perform PRP on both eyes will be kept as equal as possible A no-treatment zone of 1 clock hour from the horizontal meridian will be maintained to avoid the long ciliary nerves After treatment patients will complete a validated survey based on the numeric rating scale NRS to assess pain levels for each eye treated
