A 57-year-old Black man presented with the recent onset of a pigmented temporal epibulbar lesion. As pigmentation of conjunctival epithelial lesions is correlated with complexion pigmentation, the lesion was presumed to represent a pigmented ocular surface squamous neoplasia (OSSN). Excisional biopsy, however, revealed a pigmented conjunctival seborrheic keratosis, a rare occurrence. The lesion lacked cytologic atypia. Intralesional processes of dendritic melanocytes were demonstrated by hematoxylin-eosin and Melan-A stains. Melanophages also contributed to clinical pigmentation. Subepithelial lymphocytic infiltration, elevated Ki67 proliferative rate, prominent mitotic activity, and subtle spongiosis afforded evidence of inflammation rather than malignancy in a lesion devoid of cytologic atypia.

OBJECTIVE:To assess a series of patients receiving teprotumumab therapy and objectively quantify the rates of otologic adverse events. STUDY DESIGN:A prospective cohort study of adult patients receiving teprotumumab between May 2020 and January 2022. SETTING:Tertiary referral center. METHODS:Prior to treatment initiation, an ototoxicity-specific audiometric battery was completed, which included conventional audiometry (frequencies 250-8000 Hz), ultrahigh-frequency audiometry (9000-20,000 Hz), tympanometry, speech discrimination scores, and distortion product otoacoustic emissions (DPOAEs). Testing was then repeated after treatment completion. RESULTS:In total, 35 patients were recruited, with a median (range) age of 48.5 years (21-74), and 8 (22.8%) were male. The most common subjective symptom reported was a hearing decline (25.7%), followed by aural fullness (17.1%) and tinnitus (14.3%). Fourteen patients had both pre- and posttreatment audiometric data. Among them, 3 patients (21.4%) were found to have changes in standard frequency audiometry, and 10 (71.4%) had changes in high-frequency audiometry, with 2 patients having changes in both. Less than half (n = 5) of the 11 patients with changes in standard or high-frequency pure tone hearing noted subjective hearing decline. Changes in DPOAE were noted in 4 patients out of 13 (30.7%). Two patients discontinued treatment due to hearing decline. Finally, 3 patients (8.6%) were diagnosed with patulous eustachian tube (PET) by an otolaryngologist, and another 3 patients are suspected to have PET based on symptom description during ophthalmologic follow-up. CONCLUSION:In our cohort, a high incidence of otologic symptoms was found to be associated with teprotumumab usage. Subjective hearing decline, changes in ultrahigh-frequency hearing as well as eustachian tube dysfunction may be encountered and suggest the potential ototoxicity of teprotumumab.

PURPOSE/OBJECTIVE:The purpose of this study was to describe the clinical characteristics, management, and outcomes of orbital blow-in fractures involving compression of the globe by bone fragments. METHODS:A retrospective case series and systematic literature review were performed. RESULTS:Three male patients (mean age 29 years) with orbital blow-in fractures causing globe indentation presented with extraocular movement restriction, choroidal folds, and B-scan ultrasonography demonstrating deformation of the globe contour by a hyperechoic bone fragment. All underwent surgical repair within 1 day of presentation resulting in improved visual outcomes. An additional 10 cases were identified in the literature review. The majority of patients were male (80%) with a mean age of 29 years. Fractures originated primarily from the lateral orbital wall (50%) or the orbital roof (40%). Globe compression was evident on CT of the orbit (100%) and ultrasonography (30%). Common presenting signs included decreased visual acuity (70%), restriction of supraduction (40%) or abduction (40%), choroidal folds (30%), brow laceration (40%), periorbital edema (40%), and hypoglobus (40%). Most patients underwent surgical intervention (80%) involving fracture reduction (50%) or fragment removal (38%). Reported postsurgical outcomes were excellent with resolution of diplopia, motility, and visual acuity. CONCLUSION/CONCLUSIONS:Globe indentation from blow-in fractures are rare. Clinicians should be suspicious in cases of high-velocity trauma to the superolateral orbit with hypoglobus, motility limitation, and indentation of the globe upon dilated exam. Prompt diagnosis and early surgical removal of the compressive orbital bone fragments in a multidisciplinary fashion can lead to good visual, functional, and cosmetic outcomes.

PURPOSE/OBJECTIVE:To present a protocol for audiologic monitoring in the setting of teprotumumab treatment of thyroid eye disease, motivated by 4 cases of significant hearing loss, and review the relevant literature. METHODS:Cases of hearing loss in the setting of teprotumumab were retrospectively elicited as part of a multi-institutional focus group, including oculoplastic surgeons, a neurotologist and an endocrinologist. A literature review was performed. RESULTS:An aggregate of 4 cases of teprotumumab-associated hearing loss documented by formal audiologic testing were identified among 3 clinicians who had treated 28 patients. CONCLUSIONS:Teprotumumab may cause a spectrum of potentially irreversible hearing loss ranging from mild to severe, likely resulting from the inhibition of the insulin-like growth factor-1 and the insulin-like growth factor-1 receptor pathway. Due to the novelty of teprotumumab and the lack of a comprehensive understanding of its effect on hearing, the authors endorse prospective investigations of hearing loss in the setting of teprotumumab treatment. Until the results of such studies are available, the authors think it prudent to adopt a surveillance protocol to include an audiogram and tympanometry before, during and after infusion, and when prompted by new symptoms of hearing dysfunction.

Neoadjuvant intra-arterial cytoreductive chemotherapy is used for the treatment of lacrimal gland adenoid cystic carcinomas (ACC) to improve outcomes in this condition with an otherwise dismal prognosis. We share our experience in the management of an advanced case of ACC using a novel, highly targeted intra-arterial cytoreductive chemotherapy delivery technique involving both the internal and external carotid circulation, with an attempt to correlate the effect histologically. Refinement of the chemotherapy delivery using the tumor's vascular anatomy and appropriate blood vessel selection may lead to future globe sparing procedures without compromising survival.

Background There are multiple tools available to visualize the retinal and choroidal vasculature of the posterior globe. However, there are currently no reliable in vivo imaging techniques that can visualize the entire retrobulbar course of the retinal and ciliary vessels. Purpose To identify and characterize the central retinal artery (CRA) using cone-beam CT (CBCT) images obtained as part of diagnostic cerebral angiography. Materials and Methods In this retrospective study, patients with catheter DSA performed between October 2019 and October 2020 were included if CBCT angiography included the orbit in the field of view. The CBCT angiography data sets were postprocessed with a small field-of-view volume centered in the posterior globe to a maximum resolution of 0.2 mm. The following were evaluated: CRA origin, CRA course, CRA point of penetration into the optic nerve sheath, bifurcation of the CRA at the papilla, visualization of anatomic variants, and visualization of the central retinal vein. Descriptive statistical analysis was performed. Results Twenty-one patients with 24 visualized orbits were included in the analysis (mean age, 55 years ± 15; 14 women). Indications for angiography were as follows: diagnostic angiography (n = 8), aneurysm treatment (n = 6), or other (n = 7). The CRA was identified in all orbits; the origin, course, point of penetration of the CRA into the optic nerve sheath, and termination in the papilla were visualized in all orbits. The average length of the intraneural segment was 10.6 mm (range, 7-18 mm). The central retinal vein was identified in six of 24 orbits. Conclusion Cone-beam CT, performed during diagnostic angiography, consistently demonstrated the in vivo central retinal artery, demonstrating excellent potential for multiple diagnostic and therapeutic applications. © RSNA, 2021 Online supplemental material is available for this article.

PURPOSE/OBJECTIVE(S): Lacrimal gland cancer is a rare tumor with little data regarding outcomes and optimal management. We performed a large database analysis using the National Cancer Database (NC

The double Frost suture is a useful supplement to the reconstruction of ipsilateral upper and lower eyelid defects with full-thickness skin grafts. This technique involves silk traction sutures that overlap the upper and lower eyelids to place them on maximal stretch after placement of 2 full-thickness skin grafts. It has the added benefit of protecting the cornea and compressing both grafts under 1 bolster. The authors illustrate this technique in 2 pediatric cases-a congenital melanocytic kissing eyelid nevus and a periocular burn. Each case resulted in large upper and lower anterior lamellar defects, which were reconstructed with supraclavicular and retroauricular free skin grafts. The double Frost sutures counter vertical cicatricial forces during graft healing, obviating the need for staged procedures. Both described cases resulted in excellent graft survival with minimal contracture.

ABSTRACT/UNASSIGNED:Concomitant chorioretinal folds with disc edema can be seen in cases of thyroid eye disease presenting with compressive optic neuropathy and may portend optic nerve ischemia. We describe an unusual case of a 64-year-old man who developed partial vision loss after orbital decompression.
