Cortical Visual Impairment CVI

One of the hallmark features of CVI is difficulty processing visual complexity. When the visual environment contains many objects, patterns, or competing visual elements, the brain becomes overwhelmed and may not be able to isolate or identify individual items. A child with CVI may not be able to find a specific toy on a cluttered shelf, pick out a word on a busy page, or locate a friend in a crowded playground. This difficulty with visual complexity is not a problem with the eyes. It is a problem with the brain's capacity to filter, sort, and prioritize visual information. Visual complexity symptoms include:

• Difficulty finding objects against patterned or busy backgrounds
• Better visual performance in simplified, uncluttered environments
• Overwhelm in visually busy settings like classrooms, stores, or playgrounds
• Preference for looking at simple, high-contrast objects over complex scenes
• Difficulty with pages that contain multiple images, colors, or text elements

Many people with CVI have areas of their visual field where they see better and areas where they see poorly or not at all. Unlike visual field loss from eye conditions, CVI-related field differences can fluctuate based on fatigue, complexity of the environment, and the type of visual task. A person with CVI may consistently turn their head to use a preferred visual field, may miss objects in certain areas of their visual space, or may not respond to visual information presented from specific directions. These field preferences directly affect navigation, safety, and the ability to gather complete visual information from the environment. Visual field symptoms include:

• Consistently turning the head to favor one direction when looking at objects
• Not noticing objects or people approaching from certain directions
• Better visual recognition when objects are presented in a specific area of the visual field
• Bumping into obstacles on one side more than the other

People with CVI often show a strong preference for familiar objects and may have difficulty recognizing new items or objects presented in unfamiliar contexts. The brain needs more time and effort to process visual information that it has not encountered before. A child may recognize their own cup at home but not identify a different cup at school. They may resist new environments, new materials, or changes in visual presentation because the brain requires significant effort to process anything unfamiliar. This characteristic can be mistaken for behavioral rigidity when it is actually a visual processing limitation. Recognition symptoms include:

• Strong preference for familiar objects and environments
• Difficulty recognizing objects when they appear in new contexts or positions
• Better performance with consistent, predictable visual presentations
• Resistance to new environments that may be rooted in visual processing difficulty

Many people with CVI have distinctive responses to light and color. Some are drawn to bright, colorful objects and may use color as a primary way to identify things. Others may have significant light sensitivity that makes bright environments uncomfortable. The response to light can fluctuate based on fatigue and the overall demand on the visual system. Understanding each person's specific light and color profile is important for creating environments that support their best visual function. Light and color symptoms include:

• Strong attraction to brightly colored or illuminated objects
• Using color rather than shape to identify objects
• Difficulty in environments with too much or too little light
• Visual performance that changes based on lighting conditions

CVI can affect the coordination between what the eyes see and what the hands do. A person may look at an object but reach inaccurately for it, or may reach for an object without looking at it directly. This disconnect between vision and motor action is not a motor problem alone. It reflects the brain's difficulty in using visual information to guide movement. For children, this affects learning to write, using utensils, catching a ball, and performing countless daily tasks that require vision and hand coordination to work together. Visual motor symptoms include:

• Looking at an object but reaching past it or to the wrong location
• Reaching for objects without appearing to look at them
• Difficulty with tasks that require hand-eye coordination like writing or drawing
• Better performance when allowed to use touch rather than vision to guide actions

CVI affects visual processing at multiple levels simultaneously. Visual complexity tolerance, visual field utilization, object recognition, visual motor integration, light response regulation, and sustained visual attention may all be impaired. Because these skills are interconnected, treating one in isolation often leaves the others unchanged. An integrated approach trains the visual, sensory, and perceptual systems together so the brain can build more efficient processing across the entire visual network. For people with CVI, this approach is adapted to match the person's current visual processing level and builds capacity progressively, ensuring that each step forward is sustainable.

The foundation of our Neuro-Visual Performance Training program is built on four core treatments. These work together to address the visual processing challenges that CVI creates. Each targets a different dimension of the eye-brain connection, and together they drive lasting improvement.

Vision Therapy

Often described as physical therapy for the eyes, vision therapy retrains eye teaming, focusing, and vergence skills. Vergence is the ability of the eyes to turn inward or outward together to maintain single vision. For people with CVI, vision therapy strengthens the oculomotor foundation that supports more efficient visual processing. Activities are carefully designed to work within the person's current visual capacity and gradually increase complexity as the brain builds new processing pathways.

Perceptual Training

Perceptual training targets how the brain interprets what the eyes send it. It develops skills including visual memory, visualization, spatial awareness, contrast sensitivity, and speed of recognition. For people with CVI, perceptual training is especially important because the core difficulty is in how the brain processes visual information. Training is calibrated to the person's specific CVI characteristics, building capacity in the areas where processing is most compromised.

Optometric Multi-Sensory Training (OMST)

OMST is a passive rehabilitation protocol that combines light, sound, motion, and touch. It helps the brain relearn how to filter and process sensory information. OMST works while the person rests in a low-demand setting. It allows the brain to recalibrate how it receives and organizes input from multiple senses at once. For people with CVI, OMST is especially valuable because it addresses the sensory integration difficulties that contribute to visual overwhelm in complex environments, helping the brain learn to filter and prioritize sensory input more efficiently.

Optometric Phototherapy (Syntonics)

Syntonics uses carefully selected wavelengths of light to stimulate and balance the visual system. It helps regulate the autonomic nervous system and reduce light sensitivity. By targeting specific neural pathways, syntonics supports overall visual processing and can improve peripheral vision awareness. For people with CVI, syntonics provides gentle neural stimulation that supports the development of more efficient visual processing pathways without placing cognitive demands on the person.

In addition to our core treatments, we draw from a range of advanced tools to build a program tailored to the specific CVI profile. No two patients are alike, and the combination of visual processing characteristics varies based on the cause, severity, and duration of the condition. We access every tool in the toolbox to address the unique combination of needs. The combination depends on the evaluation results and the visual challenges affecting daily life most.

• Prism lenses to shift images and reduce strain while the brain retrains, like training wheels that support progress toward independent function
• Balance and vestibular training to rebuild the connection between vision, posture, and spatial orientation
• Red light therapy to reduce neuroinflammation and support cellular recovery in brain tissue
• 3D object tracking exercises to sharpen processing speed and real-world awareness
• A large interactive screen system that trains eyes, hands, brain, and body together in real time
• Guided light-and-sound relaxation to calm the brain and support neural balance
• Vagus nerve stimulation to help shift the body from a stressed state into calm, focused function
• Home-based software to reinforce perceptual and focusing skills between office visits

Treatment involves regular in-office sessions along with home-based activities supported by the caregiver or family. Sessions are guided by a trained therapist and adapted to the person's CVI profile and developmental level. The combination of treatments is tailored to the specific visual processing characteristics identified during evaluation. Many families begin to notice improvements within the first several weeks, often starting with better visual attention, more comfortable engagement with the environment, and reduced visual fatigue. Progress is measured through objective testing so the care team and family can track the changes taking place.

We understand that not every family lives close enough to attend weekly appointments. For families traveling from out of state or internationally, we offer an intensive 12-day in-office program. This delivers concentrated treatment over a short period. The process begins with a remote consultation and review of the person's history so the care team can plan before you arrive. During the intensive, the patient receives multiple sessions per day combining vision therapy, OMST, syntonics, and other modalities. After the intensive, the family continues through a structured remote program. This includes guided exercises, virtual check-ins, and home-based tools to reinforce the gains. This approach allows families from anywhere in the world to access our full integrated program.

The reason this integrated approach works is neuroplasticity, the brain's ability to form new neural pathways through targeted practice. Think of it like learning to ride a bike. Once the brain builds a new pathway, that skill becomes automatic and enduring. The same principle applies to the visual processing skills affected by CVI. Through consistent, guided training, the brain creates new, more efficient routes for processing visual information. These are not temporary fixes. They are structural changes built to last. For children with CVI, early intervention takes advantage of the brain's heightened developmental plasticity, while adults with acquired CVI benefit from the brain's lifelong capacity for change.
