Excessive amounts of upper lid laxity and distractibility from the globe are highly suggestive of floppy eyelid syndrome (FES). We pull on the upper lid superiorly and temporally from the globe (see Figure 2). Lids that snap into place quickly are elastic and likely healthy, while lids that are slow to normalize may indicate excess laxity, functional lid malpositions, abnormal lid wiper mechanics and potentially, insufficient nocturnal lid seal. A snap test is performed by gently pulling the patient’s upper and lower eyelids away from the globe in a pinch like fashion then releasing. We can also use a simple and effective “snap test” to manually assess a patient’s lid position. In our practice, we record this in the EMR as “lid seal insufficiency,” grading the condition negative, mild, moderate or severe based on the amount of light leakage. The more light that “escapes” the interpalpebral fissure, the higher degree of dysfunction and greater exposure to desiccating stress at night (see Figure 1). If light escapes between the eyelids, the patient’s lid seal is inadequate. In a dark room, gently place a muscle light or transilluminator at the upper tarsus of a closed eye and direct the light toward the interpalpebral fissure. The test can be carried out in any exam room with basic equipment. The “Korb-Blackie Lid Leak Test” is a simple and effective way to identify dry eye and MGD patients with insufficient lid seal (3). Proactively addressing this problem is important, as desiccating stress is a known trigger for chronic inflammation leading to chronic dry eye disease (2). When the eyelids’ protective biomechanics are insufficient, they leave the ocular surface exposed at night, and desiccating stress is inevitable without a more specific and robust treatment strategy. For these patients, avoiding fans, allergens and other commonplace aggravators simply isn’t adequate. Given this understanding, it is crucially important that we adjust our diagnostic algorithms to identify dry eye and MGD patients with poor lid functionality – those patients who are particularly susceptible to nocturnal lagophthalmos. Interestingly, patients with asymptomatic dry eye show comparatively and significantly less lid seal failure, and the severity of a patient’s lid performance failure correlates heavily to the degree of dry eye symptom severity observed. Recent research establishes that compromised lid seal – a condition wherein a patient’s eye lids remain partially open during sleep – potentially affects up to 79 percent of all symptomatic dry eye patients across diverse demographic groups (1). However the treatment of choice includes weighing the upper eyelid down by surgically inserting a gold plate,” the doctor added.It is only by recognizing and minimizing the impact of nocturnal lagophthalmos that a protective ocular surface environment can be recreated. If unable to receive surgery, patients should be administered refresh tears at least four times per day to the cornea to preserve the tear film and avoid damage to the corneas. “Surgical options may include tarsorrhaphy. “Dry eye (exposure keratopahty) is an import complication of the disease,” he said Dr Maurya said that it can be both supportive care and surgical. Without enough lubrication, the eyes may become more susceptible to infections and can become scratched and damaged. Talking about the complications, if a person keeps his eyes open while sleeping, they can dry out. The procedure is used to treat droopy eyelids. “In the second scenario, lagophthalmos can occur as a complication of upper blepharoplasty, which is an operation performed to remove excess skin overlying the upper eyelid (suprapalpebral hooding) that often occurs with the aging.īlepharoplasty (eyelid surgery) is performed to look younger. Dr Maurya said that it could be genetic or acquired condition. There is not always a reason or an underlying condition that causes nocturnal lagophthalmos. Although its pathogenesis is poorly understood, facial nerve (7th Cranial Nerve) is a causal factor,” Dr Inder Maurya said. “Nocturnal Lagophthalmos is basically an anomaly of the eyelid. According to Dr Inder Maurya – Emergency Medicine & Critical Care, CEO & Founder – Foreign OPD – pathogenesis nocturnal lagophthalmos is poorly understood. This happens when your eyelids fail to cover your eyes, either partially or fully, while sleeping. According to reports, up to 20 percent of people are affected by it. Nocturnal lagophthalmos is a condition where one sleeps without closing eyelids.
