Name of the Procedure:

Oscillating Tracking Test (OTT) with Recording Alternate Name: Oscillatory Pursuit Test

Summary

The Oscillating Tracking Test (OTT) with Recording is a diagnostic procedure where a patient's eye movements are tracked and recorded while they follow a moving target. This helps assess ocular motor function and detect potential abnormalities in eye movement.

Purpose

The primary goal of this procedure is to diagnose and monitor conditions affecting eye movement and coordination. It helps in identifying issues like nystagmus, strabismus, and other ocular motor dysfunctions.

Indications

• Symptoms of dizziness, vertigo, or balance issues
• Poor eye-hand coordination
• Suspected neurological disorders
• Unexplained headaches or visual disturbances

Preparation

• No fasting required.
• Patients may be asked to avoid caffeine or certain medications that could affect eye movements.
• A basic eye exam might be conducted prior to the test.

Procedure Description

1. The patient sits comfortably in front of a screen.
2. Special goggles or electrodes may be placed around the eyes to record movements.
3. A visual target (usually a light or pattern) moves back and forth on the screen.
4. The patient is instructed to follow the target with their eyes without moving their head.
5. The system records the eye movements for analysis by a professional.

Duration

The procedure typically takes 20-30 minutes.

Setting

Performed in outpatient clinics or specialized diagnostic centers.

Personnel

• Ophthalmologist or Neurologist
• Trained technician or clinical assistant

Risks and Complications

• Generally low risk.
• Minor discomfort or difficulty in following the target.
• Very rare occurrence of eye strain or headache.

Benefits

• Provides valuable information on ocular motor function.
• Helps in early detection of neurological or eye disorders.
• Non-invasive with minimal discomfort.

Recovery

• No significant recovery time.
• Patients can resume normal activities immediately.
• Follow-up appointments may be scheduled based on results.

Alternatives

• Electrooculography (EOG)
• Video nystagmography (VNG)
• Each alternative has its pros and cons related to specificity, sensitivity, and patient comfort.

Patient Experience

• Patients may feel slight eye strain or fatigue.
• The test is generally comfortable with no need for pain management.
• Clear instructions are given to ensure ease of following the target.
