One of the other important things the TERA Dry Eye Imager by Topcon Corporation allows us to evaluate is the health of the eyelids, eyelashes, and the lid margin. A lot of patients think dry eye only has to do with tears, but in reality, the condition of the eyelids plays a major role in the overall health of the ocular surface. Inflammation along the lid margin, damaged eyelashes, clogged glands, or debris around the lashes can all contribute to chronic dry eye symptoms, irritation, redness, fluctuating vision, and discomfort throughout the day.
What’s impressive about this technology is that it gives us highly detailed imaging of these structures, allowing us to detect subtle changes that may not be visible during a routine eye exam alone. In many patients, we can identify early inflammation or abnormalities before the symptoms become more severe. In this image, the patient’s eyelids and eyelashes actually appear relatively healthy, which is reassuring. But very often, we see patients where the lid margins are inflamed, the eyelashes are compromised, or there are signs of chronic irritation that need to be treated properly.
These findings are extremely important because untreated eyelid disease can continue to worsen the ocular surface over time. Patients may experience persistent dry eye symptoms, blurry vision, burning, tearing, or sensitivity to light without fully understanding the underlying cause. By identifying these issues early with the TERA system, we can create a more targeted treatment plan and address the root cause instead of simply masking the symptoms.
