Purpose:The lateral tarsal strip (LTS) procedure is commonly used to correct eyelid malposition. When performing LTS, some surgeons elect to remove conjunctiva from the tarsal strip, while others do not. It has been hypothesized that without conjunctival stripping, the buried conjunctival tissue can cause complications such as inclusion cysts and granulomas. However, there is limited data comparing LTS cases with and without conjunctiva removal. The authors sought to evaluate whether conjunctival stripping had any impact on complication rates with LTS.Methods: LTS operations for ectropion correction were retrospectively reviewed and were separated into 2 cohorts, Con (conjunctiva not removed) or Coff (conjunctival removed). Charts were reviewed for outcomes and complications including inclusion cyst formation, granuloma formation, wound dehiscence, infection, and focal rim tenderness.Results: The complication rate was 10% versus 8% for Con versus Coff respectively (p = 0.54). The common complications of LTS surgery were granuloma (4%), wound dehiscence (3%), focal rim tenderness (3%), and infection requiring antibiotics (<1%). There was no significant difference in these complications between the Con and Coff cohorts.Conclusions: Complications in both groups were minimal, similar to prior studies, and there was no difference between the 2 cohorts. While it has been suggested that buried conjunctiva may result in increased complication rates, the author's findings suggest that removing the tarsal conjunctiva is a superfluous step in the LTS surgery and does not affect complication rates.
Purpose: To assess the sensitivity and specificity of superior visual field tests administered in virtual reality (VR) with eye tracking (VR-ET) and without eye tracking (VR0) for the fulfillment of insurance coverage criteria for functional upper eyelid surgery as compared with standard automated perimetry (SAP). Methods: This prospective cross-sectional study included 78 eyes from 41 patients with ptosis, brow ptosis, and dermatochalasis undergoing functional upper eyelid surgery evaluation. Participants underwent serial superior visual field tests using SAP and VR0 or VR-ET in randomized order. Fulfillment of insurance coverage criteria for blepharoplasty was defined as a 30% increase in the grid seen from the untaped to the taped state. The main outcome measure was the sensitivity and specificity of VR0, VR-ET, and overall VR in meeting insurance coverage criteria as compared with SAP. Results: VR had a sensitivity of 84.1% and specificity of 67.6%, with no significant difference between VR0 and VR-ET. SAP agreed on insurance coverage criteria fulfillment with VR0 in 28 (71.8%) eyes and with VR-ET in 32 (82.1%) eyes. Insurance coverage criteria fulfillment rates varied significantly by diagnosis on SAP (p = 0.012) but not VR (p = 0.059). Conclusions: VR may be an alternative to SAP for functional upper eyelid surgery evaluation. Future studies are needed to determine differences in patient satisfaction, testing and waiting time, and test-retest reliability between VR and SAP.
