About this study

Official title: Pain Control and Subconjunctival Hemorrhage Size After Intravitreal Injection Using Cooled Anesthetic Eye Drops and Antiseptics: A Double-Blind Randomized Controlled Trial

Intravitreal injections (IVI) are the mainstay of treatment modality in many ophthalmologic diseases including neovascular age-related macular degeneration (AMD), diabetic retinopathy and retinal vascular occlusions. Patients endure monthly IVI for several years. Although standardized topical anesthesia protocols are being carried out, many still suffer from pain during and after the procedure. Previous studies at the investigators clinic have demonstrated that alpha-agonist eye drops and cool eye compresses can be successfully used in order to reduce pain levels when administered prior to IVI. In the current research, the investigators wish to study whether cooled anesthetic eye drops and antiseptics can be utilized as well to reduce the pain and subconjunctival hemorrhage caused by bevacizumab IVI.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cooled eye drops and povidone-iodineProcedure or surgery

    Cooled oxybuprocaine HCl 0.4% and lidocaine HCl 2% eye drops and cooled povidone-iodine (cul-de-sac 5% povidone-iodine and 10% povidone-iodine).

Study groups in NCT04827836
Study groupRoleWhat they receive
Cohort A - Room-temperature eye drops and povidone-iodineNo interventionParticipants will receive a standardized topical anesthesia protocol of oxybuprocaine hydrogen chloride (HCl) 0.4% and lidocaine HCl 2% eye drops. Each drop will be instilled 3 times (one drop): At 10 minutes, 5 minutes, and just before the injection. Before the injection patients will receive cul-de-sac 5% povidone-iodine (3 drops) and the peri-ocular skin will be disinfected using a 10% povidone-iodine. A standard intravitreal injection of bevacizumab, 1.25 mg/0.05 ml will be performed through the pars plana with a 30-gauge needle, 3.5 mm from the corneal limbus, at the superior-temporal quadrant. Following the injection, a cotton swab absorbed with 5% povidone-iodine will be applied to the injection site.
Cohort B - Cooled eye drops and povidone-iodineExperimentalParticipants will receive the same treatment as cohort A, using cooled eye drops and povidone-iodine (5 degree Celsius).
Receives: Procedure: Cooled eye drops and povidone-iodine

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Participant's discomfort after intravitreal injection (IVI) as assessed by the visual analog scale (VAS) and pain sensitivity questionnaire (PSQ).

    The VAS will be used to measure participant's discomfort, itching, burning, and pain (the VAS scale ranges from 0-10, '0' being no pain at all and '10' being the most severe pain). For each participant, tolerability score will be calculated by averaging the participant's discomfort, itching, burning, and pain. To estimate the participant's baseline pain scores, a self-reported pain sensitivity questionnaire, the PSQ, will be used prior to IVI. This is a validated 17-item questionnaire designed to assess an individual's baseline pain sensitivity.

    Measured: Minute 1

  2. Participant's discomfort after intravitreal injection (IVI) as assessed by the visual analog scale (VAS) and pain sensitivity questionnaire (PSQ).

    The VAS will be used to measure participant's discomfort, itching, burning, and pain (the VAS scale ranges from 0-10, '0' being no pain at all and '10' being the most severe pain). For each participant, tolerability score will be calculated by averaging the participant's discomfort, itching, burning, and pain.

    Measured: Hour 2

  4. Participant's discomfort after intravitreal injection (IVI) as assessed by the visual analog scale (VAS) and pain sensitivity questionnaire (PSQ).

    The VAS will be used to measure participant's discomfort, itching, burning, and pain (the VAS scale ranges from 0-10, '0' being no pain at all and '10' being the most severe pain).

    Measured: Hour 24

Secondary outcomes (1)
  1. Participant's subconjunctival hemorrhage (SCH) size after intravitreal injection (IVI) as evaluated by a slit lamp examination.

    SCH size following IVI will be photographed using a slit lamp camera at a uniform magnification and quantified using an image analysis software.

    Measured: Minute 10

Questions about this trial

What is this clinical trial studying?

A study testing Cooled eye drops and povidone-iodine in people with Intravitreal Injection and Pain, run by Wolfson Medical Center at 1 site in Israel.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
