1. Indications

The retinal polarization scan is indicated for the evaluation of specific ocular conditions and symptoms that may affect visual alignment and overall eye health. The following are the primary indications for performing this procedure:

• Strabismus - A condition where the eyes do not properly align with each other when looking at an object, which can lead to visual confusion and amblyopia if untreated.
• Defocusing Problems - Issues that cause small angles of visual misalignment, which may contribute to difficulties in focusing and clear vision.
• Amblyopia - Also known as "lazy eye," this condition occurs when the brain favors one eye over the other, often due to misalignment or other visual impairments.

2. Procedure

The retinal polarization scan involves a series of methodical steps to ensure accurate assessment of the retina. The procedure is as follows:

• Preparation of the Patient - The patient is positioned comfortably, and any necessary preliminary assessments are conducted to ensure the suitability of the scan. The healthcare provider may explain the procedure to the patient to alleviate any concerns.
• Application of Polarized Near-Infrared Light - The scanning device is calibrated, and polarized near-infrared light is directed towards the retina. This light is specifically modulated to enhance the detection of polarization changes as it interacts with the nerve fibers in the fovea.
• Circular Scanning Motion - The device performs a circular scanning motion around the retina of each eye. This movement allows for comprehensive coverage and assessment of the retinal area, capturing detailed polarization-related changes.
• Data Analysis - The reflected light from the ocular fundus is analyzed by the device. The system processes the polarization changes detected during the scan, which are critical for identifying any abnormalities.
• Automated Report Generation - Upon completion of the scan, the device generates an automated report that summarizes the findings. This report is crucial for the healthcare provider to interpret the results and determine the appropriate course of action for the patient.

3. Post-Procedure

After the retinal polarization scan, patients may be advised to follow specific post-procedure care instructions. Typically, there are no significant recovery concerns associated with this non-invasive procedure. However, patients may experience temporary visual disturbances due to the use of bright light during the scan. It is recommended that patients avoid driving or operating heavy machinery until they feel comfortable. The healthcare provider will review the automated report with the patient, discussing any findings and potential next steps in management or treatment based on the results of the scan.
