Excessive scleral show above the iris, also known as upper eyelid retraction, can arise from various underlying causes. Addressing this condition necessitates a comprehensive evaluation to determine the etiology, which may range from thyroid eye disease (Graves’ ophthalmopathy) to prior surgical interventions impacting eyelid positioning. Corrective strategies are tailored to the specific diagnosis and severity of the retraction. For example, if the underlying cause is thyroid-related, management of the thyroid condition is paramount, often in conjunction with ophthalmic interventions.
The functional and aesthetic significance of correcting excessive scleral show is considerable. Functionally, it minimizes ocular surface exposure, thereby mitigating symptoms of dryness, irritation, and potential corneal damage. Aesthetically, correcting eyelid retraction contributes to a more natural and balanced appearance, enhancing overall facial harmony. Historically, surgical approaches to addressing this condition have evolved significantly, with advancements in techniques allowing for more predictable and less invasive correction.
