Effectiveness of Osteopathy as an Adjunct to Optometric Vision Therapy in Vergence Disorders

Vergence disorders are common binocular vision conditions that can cause symptoms such as eyestrain, blurred vision, headaches, and difficulty maintaining clear vision during near tasks. These symptoms are particularly frequent in situations involving sustained near visual demand, such as prolonged use of digital devices, which is increasingly common in daily life. Optometric vision therapy is considered the reference treatment for vergence disorders. However, not all individuals respond in the same way, and some continue to experience symptoms despite appropriate treatment. For this reason, adjunct therapeutic approaches are being explored to improve clinical outcomes. The purpose of this study is to evaluate whether osteopathic manual therapy, when used as an adjunct to optometric vision therapy, provides additional benefits compared with vision therapy alone or vision therapy combined with a sham osteopathic intervention. This randomized, controlled, double-blind clinical trial will compare three parallel groups and will assess changes in vergence function, oculomotor performance measured by video-oculography, and symptom improvement related to vergence disorders.

Home-based Vision Therapy

Post-concussive vision symptoms affect many Veterans who have experienced traumatic brain injury (TBI). One common issue is trouble with near vision, a problem that may persist long after the acute injury. Double vision or difficulty focusing on close objects can affect reading and depth perception. Poor reading can interfere with academic or work performance, and loss of near focusing can affect jobs that require fine motor tasks like machining and electrical work. Even having trouble using a smartphone can have a substantial impact on both work and social function. Near vision impairment after TBI is not well understood, and treatments are limited. The goal of this project is to investigate novel virtual-reality assessments and training games to improve the near vision diagnosis and home-based rehabilitation. Restoring normal near vision function could have a large impact on the fulfillment of Veterans' educational, career, and overall life goals.

Effect of Oculomotor Therapy in Individuals With Convergence Insufficiency

The aim of this study is to investigate the effect of oculomotor therapy in individuals with ocular convergence insufficiency.

Efficacy Of Pencil Pushup Exercise Vs Base Out Exercising Prism's In Patient With Convergence Insufficiency

Convergence insufficiency (CI) is a prevalent binocular vision disorder that leads to symptoms such as eye strain, headaches, and blurred vision during near work. This study aims to evaluate and compare the efficacy of pencil pushup exercises versus base-out exercising prisms in the management of CI. A Randomized Controlled Trial (RCT) will be conducted with 28 participants, using non-probability convenience sampling from SIGHTON Optix, Lahore. Participants will be randomly assigned to either the experimental group (receiving base-out exercising prisms) or the control group (receiving pencil push up exercises). The study will assess symptom improvement using the Convergence Insufficiency Symptom Survey (CISS), near point of convergence (NPC).

Natural History of MTBI-related Convergence Insufficiency & Effectiveness of Vision Therapy for MTBI-related CI

The design of this project is a pilot study, a type of feasibility study conducted in preparation for subsequent RCTs that will assess the effectiveness of office-based vergence/accommodative therapy with movement (OBVAM) for mTBI-related convergence insufficiency.

Non-invasive Brain Stimulation for Treating Symptomatic Convergence Insufficiency

The goal of this randomized controlled trial is to test the effectiveness of non-invasive brain stimulation in treating adults with symptomatic convergence insufficiency compared to vergence/accommodative therapy. The main questions it aims to answer are: 1. Can non-invasive brain stimulation shorten the treatment time of office-based vergence/accommodative therapy for convergence insufficiency? 2. Is non-invasive brain stimulation alone just as effective as office-based vergence/accommodative therapy in treating convergence insufficiency? The investigators hypothesize that non-invasive brain stimulation will shorten the treatment time from 12 weeks to 8 weeks of office-based vergence/accommodative therapy and that non-invasive brain stimulation alone would be equally effective as office-based vergence/accommodative therapy in improving symptomatic convergence insufficiency. Participants will be randomized into one of three treatment groups: 1. Non-invasive brain stimulation with office-based vergence/accommodative therapy. 2. Sham stimulation with office-based vergence/accommodative therapy. 3. Non-invasive brain stimulation only. Researchers will compare baseline measurements of near point of convergence (NPC) and positive fusional vergence (PFV) to post-treatment measurements for each group.

Eye Recovery Automation for Post Injury Dysfunction (iRAPID)

This study will test a portable virtual reality (VR) system with integrated eye tracking called Virtual Eye Rotation Vision Exercises (VERVE). The proposed VERVE platform will deliver vergence therapy in an automated manner. This research will involve 30 non-traumatic brain injury (TBI) binocularly normal (BNC) Veterans and 50 post-traumatic convergence insufficiency (PTCI) Veterans who will undergo Active and Sham therapy (equally divided groups) to determine the effectiveness of VERVE vergence therapy.

Effectiveness of Virtual Reality Vision Therapy - VERVE

The purpose of this research study is to see how well the treatment of a participant's eye coordination and/or focusing problems improves eye muscle responses and symptoms of eyestrain. We will use an entertainment device called a virtual reality headset to play a custom-designed video game to find out how well the treatment of binocular vision improves a participant's coordination and/or focusing problem. The virtual reality headset uses eye-trackers to monitor progress in a totally objective manner. Objective testing allows the doctor to determine the results without relying on a participant's ability to answer questions or respond verbally in any way. We will compare the results of a participant before and after playing the video game.
