Abstract

PURPOSE: To analyze the outcomes of patients who transitioned from a weight to a spring.

METHODS: Case series original investigation. Five consecutive patients undergoing "enhanced" palpebral spring insertion status post gold weight insertion were identified. Outcome measures included visual acuity, lagophthalmos, margin reflex distance 1, and corneal epithelial defects. Subjective outcomes included need for eye lubrication, closure and rapid blink, and symptoms of discomfort and dryness. This study was reviewed by an accredited Institutional Review Board (IRB) and granted exempt status according to federal regulations.

RESULTS: Mean visual acuity post weight versus spring was 20/200 (logMAR 1.0, Std Dev. -0.6) and 20/25 (logMAR 0.1, Std Dev. -0.1), respectively (p = 0.0214, CI 0.231 to 1.670). Mean lagophthalmos post weight (3.5 mm, Std Dev. -2.8) versus post spring (0.2 mm, Std Dev. -0.5). Margin reflex distance 1 improved by a mean of 1.4 mm (gold wt -0.6, Std Dev. -0.5/spring -2.0, Std Dev. -0.4) (p = 0.0016, CI -1.773 to -0.977). Superficial punctate keratopathy was present in all patients with weights and present in no patients post transition (p = 0.0079). Post transition, three of five patients rarely required lubrication and experienced a more satisfactory blink rate.

CONCLUSION: Patients with lagophthalmos due to cranial nerve seven palsy who have undergone gold weight placement but continue to exhibit objective and subjective corneal symptoms may have symptomatic improvement with the transition to a palpebral spring.
