A severe dry eye condition, affecting millions, can sometimes lead to debilitating sensitivity to sunlight, a phenomenon that can be managed with targeted treatments. Dr. Martin Scurr addresses the concerns of a patient who has experienced these issues for years.
The patient has been undergoing hospital treatment for a severe dry eye condition, which included the insertion of plugs into her tear ducts and the use of eye drops. Approximately six years ago, she also developed a sensitivity to sunlight. Despite a specialist's recommendation of heated eye pads and lutein supplements, her light sensitivity has not improved.
Dr. Scurr explains that the treatments received are standard for severe dry eyes, often caused by blockages in the meibomian glands. These glands produce oil crucial for the outer layer of tears, helping to lubricate the eyes. The decline and thickening of this oil are common with age, potentially leading to inflammation and sore eyelids. In severe cases, tear duct plugs help reduce tear fluid drainage, alleviating dryness.
The eye drops mentioned, such as Ikervis, work by suppressing inflammation, while others like Clinitas and Xailin act as lubricants to ease symptoms while the anti-inflammatory medication takes effect.
Photophobia, or light sensitivity, is often a component of dry eye syndrome. When tears offer less protection, the eye's exposed nerves become more reactive. Heated eye pads are suggested to address the underlying cause of dry eyes by softening the oil in the meibomian glands, aiding its release. Alternatives to specialized pads include a warm compress or a microwaveable eye mask, used for ten minutes once or twice daily.
Lutein supplements, on the other hand, are not directly for treating dry eye. Their purpose is to protect the macula, the part of the eye responsible for sharp vision.
