Pilot Study of TENS for Ocular Pain
Eye PainApproximately 20% of Veterans have a diagnosis of dry eye (DE) syndrome which is often accompanied by ocular pain that significantly impacts activities of daily living. Currently very few treatments are available for chronic ocular pain, likely because the mechanisms underlying this type of pain have only recently begun to be studied. New treatments that target the neuropathic mechanisms contributing to this type of pain are needed. The proposed research provides a crucial step in addressing the lack of treatments for neuropathic ocular pain by validating the methodology needed to support a randomized controlled trial of transcutaneous electrical nerve stimulation (TENS). TENS is a non-pharmacologic, non-addictive, non-invasive treatment that has been shown to be effective in other chronic pain conditions. The present pilot study aims to address the need for preliminary support of safety and efficacy of TENS for ocular pain, t to advance the study of new treatments for the long-term relief of chronic ocular pain and its impact on health.
Azithromycin for Meibomian Gland Disease
Dry EyeNeuropathic Eye Pain3 moreThis study aims to elucidate the effectiveness of oral azithromycin in treating symptomatic dry eye syndrome secondary to Meibomian gland dysfunction.
Evaluate the TetraLens, a Tetracaine Releasing Therapeutic Bandage Contact Lens in Patients Undergoing...
Ocular Pain Following Bilateral Photorefractive Keratotomy (PRK)The goal of this clinical trial is to determine the safety, efficacy, and comfort of the investigational TetraLens bandage contact lens in patients who have undergone photorefractive keratectomy (PRK). The main question[s] it aims to answer are: Understand benefit of managing pain following the surgical procedure Understand the safety of the Tetralens Participants will be asked to wear theTetraLens BCL in one eye for 6 days post-operatively and: document the daily quantity of oral analgesics needed and report ocular pain and contact lens comfort. Researchers will compare the study lens in one eye to a control lens in the contralateral (other eye)
Alternating and Direct Current Stimulation for Neuropathic Eye Pain
Eye PainNeuropathy2 moreThe goal of this clinical intervention is to test if two forms of transcranial current stimulation, transcranial direct current stimulation (tDCS) or transcranial alternating current stimulation (tACS) can alleviate neuropathic eye pain in a sample of 20 patients. The main aims are: Test if tDCS/tACS can alleviate neuropathic eye pain and/or other cerebral symptoms: brain fatigue, migraine, light sensitivity, etc. Test if one stimulation method is superior to the other Patients will be treated for a total of fifteen 30-minute stimulation sessions, three times a day over a five-day period, each stimulation separated by approximately 4 hours, with either active tACS or tDCS over the scalp corresponding to primary sensory and motor areas. The patients will have questionnaires to monitor subjective experiences and pupillometry before and after treatment to monitor experimental outcomes.
Pilot Study to Evaluate SYL1001 Safety and Effect in Patients With Ocular Pain
Ocular PainDry Eye SyndromeThe aim of this pilot study is to compare the analgesic effect of SYL1001 versus placebo in patients with ocular pain associated with Dry Eye Syndrome. General and local tolerability are also evaluated.
Study of SAF312 as an Eye Drop for Treatment of Eye Pain Following Photorefractive Keratectomy (PRK)...
Postoperative Ocular Pain After PRK SurgeryThe purpose of this study is to determine if SAF312 eye drops have an adequate safety and efficacy profile to justify further clinical development for the treatment of ocular pain associated with corneal epithelial defect such as after photorefractive keratectomy (PRK) surgery
Dose-finding Study to Assess the Safety and Effect of SYL1001 in Patients With Ocular Pain
Ocular PainDry Eye SyndromeThe aim of this pilot study is to compare the analgesic effect of two strengths of SYL1001 eye drops versus placebo in patients with ocular pain associated with Dry Eye Syndrome. General and local tolerability are also evaluated.
Study to Evaluate the Ocular Tolerance of SYL1001 in Healthy Volunteers
Ocular PainDry EyeThe purpose of this study is to determine whether SYL1001 is safe for the prevention and treatment of ocular pain and dry eye syndrome.
Cool vs Room-temperature Artificial Tears
Diabetic Retinopathy With Macular Edema of Both Eyes (Diagnosis)Central Retinal Vein Occlusion With Macular Edema6 moreBackground and Objective: To evaluate the efficacy of cooled versus room temperature artificial tears in reducing post intravitreal injection (IVI) ocular discomfort. Patients and Methods: Patients receiving IVI were randomized to either cooled or room temperature tears intervention groups. Both groups rated their ocular discomfort following IVI before intervention and again after administration of cooled or room temperature tears.
Effect of Trigeminal Nerve Stimulation on Corneal Nerves and Chronic Ocular Pain
Dry EyeNeuropathic Pain1 moreIndividuals with dry eye tend to present with ocular pain which persists despite the use of topical treatment. This could be secondary to somatosensory impairment attributable to neuropathic pain. The purpose of this study is to evaluate the effect of trigeminal nerve stimulation (TNS) on corneal nerves and chronic ocular pain in patients with dry eye.
