Study of ocular motility in neurodegenerative diseases 

What is a study of ocular motility in neurodegenerative diseases? 

A study of ocular motility is a diagnostic technique that evaluates eye movements and their coordination. In the context of neurodegenerative diseases, this test makes it possible to identify specific alterations in eye movement patterns that may be related to progressive neurological damage. It is a key tool for early diagnosis, clinical monitoring, and therapeutic planning in patients with conditions such as Parkinson’s, Alzheimer’s, multiple sclerosis, among others. 

What is this procedure for? 

Studies of ocular motility are primarily used in: 

  • Diagnosis of neurodegenerative diseases: to identify alterations in eye movements that may be indicative of neurological dysfunction. 
  • Evaluation of visual symptoms: it is used to analyze problems such as double vision, difficulty focusing, or uncoordinated eye movements. 
  • Treatment planning: it helps design visual rehabilitation strategies tailored to the patient’s needs. 
  • Clinical follow-up: it can be used to monitor the progression of diseases and assess the response to treatment. 
  • Clinical research: it is used to study the relationship between eye disorders and the underlying mechanisms of neurodegenerative diseases. 

Benefits of advanced technology in studies of ocular motility in neurodegenerative diseases 

The procedure combines clinical tests and advanced technology to measure the speed, amplitude, and accuracy of eye movements. These tests may include techniques such as videonystagmography, eye tracking using infrared cameras, and computerized analysis of movement patterns. 

What does the procedure involve?

The procedure for studying ocular motility involves: 

  • Preparation:

    During the initial consultation, the doctor will ask you some questions to learn about your medical history and better understand your symptoms. It is recommended that you wear comfortable clothing without any metal components. In addition, if you are taking any medication that may affect your neurological or visual condition, inform the medical team so that they can take it into account. 
  • During the procedure:

    During the procedure, the specialist will observe your eye movements as you follow moving objects or perform specific tasks. Depending on the case, instrumental tests such as videonystagmography, which records eye movements with specialized cameras, or computerized eye tracking, which analyzes movement patterns in real time, can be performed.  

      

    Your ability to fix your gaze and make rapid movements between two points can also be assessed using fixation and saccadic tests. All data will be processed with specialized software to generate a detailed report. In total, the procedure usually lasts between 30 and 60 minutes. 
  • After the procedure:

    You can resume your normal activities immediately after the procedure. A neuro-ophthalmology specialist will analyze and interpret the results and send them to your doctor. 

Recommendations for the procedure 

  • Avoid sudden movements: during the procedure, it is essential that you follow the technician’s instructions to ensure accurate results. 
  • Rest beforehand: it is important that you come well-rested to avoid eye strain during the procedure. 
  • Companion: in some cases, it may be helpful to come accompanied by a family member who can provide additional information about your behavior. 

Are there any risks?  

A study of ocular motility is a safe and non-invasive procedure. However, some specific aspects of the procedure may cause mild discomfort: 

  • Temporary discomfort: when using devices such as infrared cameras or specialized glasses. 
  • Eye strain: due to the duration and demands of some tests. 

To ensure your procedure runs smoothly, we ask that you arrive before the scheduled time. This will allow us to complete the necessary administrative and clinical preparation. 

Before the procedure, we will give you the Informed Consent form, a document with important information that you must read and sign. 

If your appointment is for an MRI, it is crucial that you inform us about the presence of pacemakers, metallic objects, prostheses (including dental prostheses), tattoos, or drug infusion devices such as insulin pumps. 

These diagnostic tests are very safe, but as with any medical procedure, there is still the unlikely possibility of an incident.
