Diagnosing CVI: Process and Tools

Diagnosing Cerebral Visual Impairment (CVI) is a comprehensive process that involves several steps and tools to ensure an accurate understanding of an individual’s visual processing capabilities. Unlike other visual impairments, CVI is not solely about the eyes themselves but rather how the brain interprets visual information. Due to this complexity, the diagnosis requires a multidisciplinary approach.

Step 1: Clinical History and Observations
First, we gather a detailed clinical history that includes prenatal, perinatal, and postnatal events, alongside developmental milestones, especially those related to vision. This is crucial as CVI often has correlations with other neurological conditions. Plus, observations of the child’s or individual’s visual responses in different environments provide initial insights into potential CVI.

Step 2: Standard Eye Exams
Standard eye exams rule out or confirm any ocular issues. These exams are critical as they help to differentiate between purely ocular problems and those stemming from the brain’s processing of visual inputs.

Step 3: Specialized CVI Assessments
Next, specialized assessments focusing specifically on visual processing are conducted. Tools such as the CVI Range, developed by Dr. Christine Roman-Lantzy, are employed to evaluate visual functioning in individuals suspected of having CVI. The CVI Range assesses a person’s unique responses to visual stimuli, considering the ten characteristics most commonly associated with CVI.

Step 4: Neurological Assessments
In conjunction, neurological assessments may be conducted to identify any underlying brain abnormalities. MRI or CT scans can provide valuable information about the structural integrity of the visual pathways and brain, which plays a significant role in diagnosing CVI.

Throughout this process, collaborating with specialists in neurology, ophthalmology, and special education ensures a comprehensive understanding of each case.
