Purpose
Eyelid surgery for dermatochalasis is typically reimbursed by insurance only after objective documentation of visual field obstruction, most commonly using the Humphrey Field Analyzer (HFA). However, HFA testing can be taxing to both patients and staff. This case report introduces a novel, handheld measurement technique designed to quantify upper eyelid laxity and explore its relationship with visual field obstruction, potentially minimizing reliance on HFA testing.
Methods
Eyelid laxity was assessed using a handheld instrument designed to apply tension to the upper eyelid and measure the resulting excess skin displacement relative to the eyelid margin. Patients gently closed their eyes during measurement, and displacement values were recorded at both central and lateral points. Standard HFA visual field testing was subsequently performed for comparison.
Results
Examination revealed dermatochalasis. Central and lateral eyelid skin displacement measurements were 6.5 mm and 7.8 mm, respectively. The patient tolerated the measurements without difficulty. HFA testing demonstrated significant superior visual field obstruction consistent with clinical findings.
Conclusion
This method offers a rapid, noninvasive approach for predicting visual field obstruction in patients with dermatochalasis. It may provide a reproducible, objective screening tool to aid surgical candidacy assessments, reduce reliance on time-consuming visual field testing, and alleviate healthcare resource burdens. Further study in larger cohorts is warranted.
