Greater Proptosis Is Not Associated With Improved Compressive Optic Neuropathy in Thyroid Eye Disease

Nanda, Tavish; Dunbar, Kristen E; Campbell, Ashley A; Bathras, Ryan M; Kazim, Michael
PURPOSE/OBJECTIVE:Despite the paucity of supporting data, it has generally been held that proptosis in thyroid eye disease (TED) may provide relative protection from compressive optic neuropathy (CON) by producing spontaneous decompression. The objective of this study was to investigate this phenomenon in patients with bilateral TED-CON. METHODS:We retrospectively reviewed the charts of 67 patients (134 orbits) with bilateral TED-CON at Columbia-Presbyterian Medical Center. Significant asymmetric proptosis (Hertel) was defined as ≥ 2 mm. Significant asymmetric CON was defined first, as the presence of an relative afferent pupillary defect. Those without an relative afferent pupillary defect were evaluated according to the TED-CON formula y = -0.69 - 0.31 × (motility) - 0.2 × (mean deviation) - 0.02 × (color vision) as previously established for the diagnosis of TED-CON. A difference in the formula result ≥ 1.0 between eyes was considered significant. Patients were then divided into 4 groups. RESULTS:Forty-one of 67 patients demonstrated asymmetric CON (29 by relative afferent pupillary defect, 12 by formula). Twenty-one of 67 patients demonstrated asymmetric proptosis. Only 5 of 12 (41.6%) of the patients who had both asymmetric proptosis and asymmetric CON (group 1) showed greater proptosis in the eye with less CON. Twenty-nine patients (group 2) showed that asymmetric CON occurred despite symmetrical proptosis. Seventeen patients (group 3), showed the inverse, that asymmetric differences in proptosis occurred with symmetrical CON. CONCLUSION/CONCLUSIONS:Despite commonly held assumptions, our results suggest that greater proptosis is not associated with improved TED-CON. Combining groups 1 to 3-all of which demonstrated asymmetry of either proptosis, CON, or both-91.4% of patients did not show a relationship between greater proptosis and improved CON.

Improvement in Both Primary and Eccentric Ocular Alignment After Thyroid Eye Disease-Strabismus Surgery With Tenon's Recession

Scofield-Kaplan, Stacy M; Dunbar, Kristen; Stein, Gregory; Kazim, Michael
PURPOSE/OBJECTIVE:To evaluate the improvement in primary and eccentric gaze ocular alignment in thyroid eye disease (TED) patients undergoing horizontal strabismus surgery with Tenon's recession. METHODS:This is an Institutional Review Board-approved retrospective analysis of TED patients undergoing horizontal strabismus surgery for esotropia. The study included all patients from 2007 to 2016 operated on by a single surgeon at Columbia University Medical Center. Surgical success was defined as the ability to fuse at both near and distance either without prismatic correction or with less than 10 prism diopters (PD) of correction. Measurements of ocular alignment were also made in eccentric fields of gaze. This study was Health Insurance Portability and Accountability Act compliant with protection of individually identifiable information. RESULTS:Thirty-eight patients with TED and restrictive horizontal strabismus underwent unilateral or bilateral medial rectus recession to relieve diplopia. All patients underwent Tenon's recession with dissection of Tenon's from the overlying conjunctiva permitting it to retract into the orbit. Overall the success rate was 87% with a reoperation rate of 7.9%. The improvement in horizontal deviation in both primary and eccentric gaze was statistically significant (p < 0.001). The change in vertical deviation in the 5 cardinal positions of gaze was not statistically significant. The postoperative change in vertical deviation was not proportional to the preoperative horizontal deviation or the amount of horizontal recession. CONCLUSIONS:Due to the preoperative incomitance of ocular deviations in TED patients, persistent postoperative eccentric misalignment is expected. The addition of Tenon's recession to TED-horizontal strabismus surgery led to statistically significant improvement in ocular alignment in both primary and eccentric gaze. This is the first study of TED-strabismus surgery to analyze the postoperative results in positions outside of primary and reading gaze. The authors postulate that the release of scar tissue by the addition of Tenon's recession contributes to these improvements.

Utility of PROSE Device in the Management of Complex Oculoplastic Pathology

Scofield-Kaplan, Stacy M; Dunbar, Kristen E; Campbell, Ashley A; Kazim, Michael
PURPOSE/OBJECTIVE:To describe the use of Prosthetic Replacement of the Ocular Surface Ecosystem (PROSE) device in the management of complex oculoplastic pathology. METHODS:The authors retrospectively reviewed the records of individuals over 18 years of age who were referred and successfully fit with the PROSE scleral device between January 1995 and June 2015. RESULTS:Nine cases were identified that had complex oculoplastic disease and severe corneal surface disease. All patients with ptosis had improvement in marginal reflex distance-1 following PROSE and 5 of 7 patients with ptosis were spared further surgical intervention. Two underwent surgical repair with successful corneal stabilization with PROSE. Those with eyelid malposition including ectropion, entropion, or trichiasis experienced improvement in their corneal surface and deferred further surgical intervention. CONCLUSIONS:These cases highlight the use of the PROSE device to elevate the upper eyelid in patients with lagophthalmos and ptosis, stabilize the corneal surface to allow for additional eyelid surgery to be performed safely, and protect the corneal surface in patients with intractable trichiasis and entropion. Prosthetic Replacement of the Ocular Surface Ecosystem should be considered in patients with complex oculoplastic pathology to improve visual function, corneal surface disease, and eyelid position.

Treatment of Pediatric IgG4-Related Orbital Disease With TNF-α Inhibitor [Case Report]

Jalaj, Sanjai; Dunbar, Kristen; Campbell, Ashley; Kazim, Michael
The authors describe a 9-year-old female who presented with swelling, proptosis, and tenderness of the right upper eyelid and MRI imaging demonstrating right lacrimal gland enlargement. After failing treatment with corticosteroids, the patient underwent a biopsy that was consistent with IgG4-related orbital disease. She was subsequently successfully treated with adalimumab (TNF-α inhibitor). This is the first case report of the successful use of a TNF-α inhibitor for the treatment of IgG4-related orbital disease in a child.

Lateral tarsal strip plus skin-muscle flap excision in the treatment of lower eyelid involutional entropion

Dunbar, Kristen E; Cox, Catherine; Heher, Katrinka L; Kapadia, Mitesh K
This article examines the effectiveness of skin-muscle flap excision in conjunction with a lateral tarsal strip for the treatment of involutional entropion. Ninety-six eyelids in 83 consecutive patients with involutional entropion were treated using a standardized surgical procedure. All patients underwent lower eyelid tightening with a lateral tarsal strip, dissection of a skin-muscle flap inferiorly through a subciliary incision and excision of redundant skin as well as orbicularis muscle. Follow-up data was obtained by retrospective chart review and telephone interviews. 80 patients were included in this study. The only exclusion criteria was failure to attend the 1 week follow-up appointment, n = 3. There was only one recurrence which was mild and revised under local anesthesia. Two patients had overcorrection with mild ectropion but did not require additional surgery. In those that completed their initial post-operative visit, the average time follow-up time was 502 days. Excision of a skin-muscle flap is a useful addition to lateral tarsal strip surgery in the treatment of involutional entropion and is a quick procedure producing excellent functional and cosmetic results. To our knowledge, this is the first cohort of patients to be reported using this technique where all patients had a standardized surgical approach. Additional studies are needed to compare long-term outcomes of this technique against other surgical treatments.
