Amblyopia (sometimes called 'lazy eye') is reduced vision in one eye caused by abnormal visual development early in life. The weaker (or 'lazy') eye often wanders inward and outward. Amblyopia is the leading cause of reduced vision in children and can lead to blindness if not treated. Treatments for amblyopia are glasses, and if needed, further treatment with part-time patching or penalization with atropine eye drops. Patching or atropine are administered to the stronger eye to force the child to use the weaker (amblyopic) eye. In recent years, an alternative type of therapy has emerged. It is called dichoptic treatment and involves stimulating both eyes simultaneously but with different stimuli. When it was first introduced, it was done in an office-based setting. Home-based technologies utilizing games and movies have been developed and studied to a limited extent in younger children with amblyopia. In this study, we will use a system called Luminopia. It uses a virtual reality headset to view web-based videos in which the contrast of the image seen by the stronger eye is reduced by 15% from that of the weaker eye. Luminopia has been available for use in the U.S. since 2022 and has been approved by the FDA for the treatment of amblyopia in this age group. In a previous large randomized trial, home-based dichoptic movies were shown to be superior to glasses alone but treatment effectiveness compared to patching (the gold standard for treating amblyopia) has not yet been established. If dichoptic therapy using the Luminopia system is confirmed to be at least as effective as patching, it would be an appealing alternative for treating amblyopia in young children, as it shows promise of better adherence and an easier treatment experience for the parent and the child. Children in this study would be randomized 1:1 to either the Patching Group or the Luminopia Group and followed for at least 6 months. Children in the Patching Group will have the option to do the Luminopia treatment after 6 months of patching. They will be followed for an additional 6 months. Thus, their participation will last for a total of 1 year.

The purpose of this study is to look at symptoms, thoughts, and behaviors related to the way a person sees the world. This is called visual perception. This study will also look at brain function. We will study these things in people with and without psychosis. People with psychosis see the world differently than others. For example, they may experience hallucinations. We are interested in understanding how differences in the way people see the world relate to brain circuits. This project will use visual and behavioral experiments, EEG, and Magnetic Resonance Imaging (MRI) to look at how visual perception is different in people with and without psychosis. This research study has three visits lasting 2-4 hours each. We expect that these visits will take place over 2-3 months, depending on your availability and preferences.

This study seeks to understand visual perception in people with Visual Snow Syndrome and how this relates to brain function.

The purpose of this research study is to collect timely and relevant data that will support the evolving research needs of the Inherited Retinal Disease community (IRD), in order to provide insights that can be used to improve patient management, and to inform development of future treatments. No visits, assessments, or procedures are mandated, and follow-up will be captured as part of your standard of care. The planned length of registry is of 8 years with a potential to extend the duration as needs evolve.

The clear layer at the front of the eye that covers the pupil and iris (colored part of the eye) is called the “cornea”. When the cornea is damaged, it normally heals within a few days but it may take up to 2 weeks depending on the size and depth of the defect (wound). Some corneal defects heal much slower than expected. A defect in the cornea that fails to heal within the normal time of 2 weeks despite using the best available medicines and procedures, is known as Persistent Corneal Epithelial Defect (or PCED for short). The purpose of this research study is to evaluate the safety, tolerability, and effectiveness (risks and benefits) of of NEXAGON ophthalmic gel for the treatment of PCEDs.
