Proptosis Regression After Teprotumumab Treatment for Thyroid Eye Disease.

PURPOSE: This study analyzed the degree and timing of proptosis regression after teprotumumab therapy. METHODS: A retrospective study of all patients who completed 8 teprotumumab infusions at 1 institution from January 1, 2020 to December 31, 2022. Change in proptosis was assessed in millimeters and percentages compared with immediate post-treatment and pretreatment proptosis. RESULTS: Of 119 patients with post-treatment data (mean follow-up 10.56 months, range: 3.05-25.08), 208 (87.39%) eyes of 110 patients had initial proptosis improvement. Of the 78 patients with multiple follow-up visits, 102 (65.38%) eyes of 59 patients had proptosis regression averaging 12.78% (range: 1.85-58.82%) compared with immediately post-treatment or 2.43 mm (0.5-10.0 mm). Eight (7.84%) eyes had initial documentation of regression more than 1 year after treatment, 40 (39.22%) between 6 months and 1 year, and 54 (52.94%) eyes within 6 months with 25 (46.30%) of these continuing to worsen at subsequent follow-up. Forty (25.64%) eyes of 24 patients had more proptosis at most recent follow-up than before teprotumumab, with an average regression of 1.53 mm (0.5-4.0 mm) or 7.74% (1.85-20.69%) of pretreatment proptosis. In comparison, 99 (63.46%) eyes of 54 patients maintained improvement, with reduction averaging 3.13 mm (0.5-11.0 mm) or 13.19% (1.92-41.67%) of pretreatment proptosis ( p < 0.001). CONCLUSIONS: Two-thirds of eyes had regression despite initial teprotumumab response, typically within 1 year of treatment, with ongoing worsening over time. Most patients maintained some proptosis reduction compared with before treatment despite regression, although 25% were worse than pretreatment. The occurrence of regression was independent of the pretreatment duration of clinical thyroid eye disease. Overall, compared with preteprotumumab, there was a greater amount of improvement than regression at most recent follow-up.

Perceived change in age after functional upper blepharoplasty.

PURPOSE: To evaluate the perceived age of patients before and after functional upper blepharoplasty. METHODS: Retrospective chart review of patients who underwent upper blepharoplasty by a single surgeon at an academic center. The inclusion criterion was having external photographs before and after blepharoplasty. Exclusion criteria included any other concurrent eyelid or facial surgery. Primary endpoint: perceived change in age after surgery as judged by the American Society of Ophthalmic Plastic & Reconstructive Surgery (ASOPRS) surgeons. RESULTS: Sixty-seven patients (14 men, 53 women) were included. Mean pre-operative age was 66.9 years (range 37.8-89.4) and mean post-operative age was 67.4 years (range 38.6-89). The mean perceived age pre-operatively was 68.9 years, and the mean perceived age post-operatively was 67.1 years, a change of 1.8 years (p = 0.0001 by two-tailed paired T-test). Inter-rater reliability of the observers was measured by intraclass correlation coefficient of 0.77 for pre-operative and 0.75 for post-operative photos. The decreased perceived age was 1.9 years for women, 1.4 years for men, 0.3 years for Asians, 1.2 years for Hispanics, and 2.1 years for whites. DISCUSSION: Functional upper blepharoplasty by an experienced ASOPRS surgeon was shown to reduce the perceived age of a patient by an average of 1.8 years.

Change in upper eyelid position after teprotumumab treatment for thyroid eye disease.

PURPOSE: Despite the high prevalence, treatment challenges, and significant impact of eyelid retraction on vision and quality of life among patients with thyroid eye disease, the effects of teprotumumab on eyelid retraction are not fully understood. This study evaluated change in upper eyelid position after teprotumumab. METHODS: A retrospective study of all patients who completed eight teprotumumab infusions at one institution from January 1 2020 to December 31 2022. Primary outcome was change in upper eyelid position immediately after treatment and at most recent follow-up compared to pre-treatment. RESULTS: Among 234 eyes of 118 patients, average margin reflex distance-1 (MRD1) pre-treatment was 5.25 mm (range 0-10.0, SD 1.75), 4.66 mm (1.0-9.0, SD 1.32) immediately post-treatment (p < 0.001), and 4.50 mm (0-10.0, SD 1.52) at most recent follow-up (mean follow-up duration 10.60 months). In total, 136 (58.12%) eyes of 88 patients had MRD1 reduction immediately post-treatment, averaging 1.49 mm (0.5-5.0 mm, SD 0.97). Every 1-mm increase in pre-treatment MRD1 increased the odds of MRD1 reduction by 15.03% (CI 10.52-19.72, p < 0.001) and increased the reduction amount by 0.48 mm (CI 0.39-0.57, p < 0.001). Of 154 eyes of 78 patients with most recent follow-up, 107 (69.48%) eyes had stable or further improved retraction at most recent follow-up compared to immediately post-treatment. CONCLUSIONS: This study found a modest but significant reduction in MRD1 in approximately 60% of eyes, independent of proptosis change, which was sustained by most patients over longer-term follow-up. Higher pre-treatment MRD1 corresponded with greater improvement. These results suggest an overall mild benefit of teprotumumab for upper eyelid retraction.

Recalcitrant postoperative bleeding after ectropion repair in the setting of undiagnosed chronic disseminated intravascular coagulation.

Disseminated intravascular coagulation (DIC) is characterized by abnormal activation of the coagulation cascade, which leads to simultaneous hypercoagulation and excessive bleeding. While it typically occurs in systemic diseases, such as infection, inflammation, obstetric complications, and malignancy, it can rarely manifest postoperatively. This case report describes a patient who presented with prolonged, refractory bleeding after ectropion repair via a lateral tarsal strip procedure. Due to the inability to control the patient's bleeding with conservative measures followed by surgical exploration and electrocautery, the patient underwent a hematologic work-up. Laboratory studies were consistent with DIC, attributed to his large burden of endovascular stents. He was treated with anticoagulation using apixaban in addition to tranexamic acid to achieve lasting hemostasis. This case highlights the importance of thorough preoperative assessments, even for minor surgical procedures, and systemic workup for atypical postoperative bleeding.

Lymphoma of the Lacrimal Sac: The Massachusetts Eye and Ear Experience With a Comparison to the Previously Reported Literature.

PURPOSE: To describe the frequency, clinical features, and histologic subtypes of biopsy proven lacrimal sac lymphomas, and to compare these results to the previously published literature. METHODS: A retrospective chart review was performed at a single institution from 2004 to 2017. Pathology reports, operative notes, and patients' medical charts were reviewed. RESULTS: Of 566 lacrimal sacs submitted for routine histopathologic evaluation, 16 cases of lymphoma were identified. All were low-grade, non-Hodgkin B-cell lymphomas, biopsied at an average age of 71 years. Thirteen patients (81.25%) had a pre-existing lymphoma diagnosis; the average interval between the diagnosis of systemic or nonocular adnexal lymphoma and lacrimal sac lymphoma was 7.9 years (range 2-26 years; median 5.5 years). Three cases of primary lacrimal sac lymphoma were identified. Histopathology showed 3 cases (18.75%) of follicular lymphoma, 3 (18.75%) of extranodal marginal zone lymphoma, and 10 (62.5%) of chronic lymphocytic leukemia/small lymphocytic lymphoma. Primary cases presented with epiphora and nasolacrimal duct obstruction, while secondary cases predominantly manifested as dacryocystitis. All lacrimal sac neoplasms were locally responsive (without local recurrence) to chemotherapy, radiation, or both. CONCLUSIONS: Lacrimal sac lymphoma is uncommon but should be suspected among patients with known lymphoma who develop dacryocystitis. In this series, primary lacrimal sac lymphoma most often presented as a mass or nasolacrimal duct obstruction. Chronic lymphocytic leukemia/small lymphocytic lymphoma was the most commonly identified cause of secondary lacrimal sac lymphoma. Distinguishing primary from secondary lacrimal sac lymphomas is important, as the extent of disease and histopathologic subtypes differ, which may affect patient management.

Wells Syndrome Presenting as Atypical Periorbital Cellulitis.

A 62-year-old man presented with diffuse, painless, left-sided preseptal edema, erythema, and woody induration extending to the left temple. The induration generated an orbital compartment syndrome with markedly elevated intraocular pressure necessitating lateral canthotomy and cantholysis. Although atypical for an infectious etiology, empiric broad-spectrum intravenous antibiotics were initiated with no improvement. A tissue biopsy demonstrated extensive perivascular and interstitial eosinophils with focal flame figures, and the patient was diagnosed with a severe hypersensitivity reaction or eosinophilic cellulitis (Wells syndrome). The disease process remitted rapidly upon initiation of oral prednisone. Wells syndrome is a rare inflammatory eosinophilic dermatosis, most often presenting in the limbs and trunk, with few reports of facial and periorbital involvement. This case highlights the importance of considering Wells syndrome in the differential diagnosis of atypical periorbital cellulitis that is nonresponsive to antibiotics and reviews the clinicopathologic nature of this disease.

Posterior Ischemic Optic Neuropathy in the Setting of Cocaine-Induced Orbital and Sinonasal Inflammation.

Intranasal cocaine abuse can lead to significant sinus and orbital complications, including optic neuropathy. A 46-year-old man with a history of recurrent cocaine-induced sino-orbital inflammation and infection with bony destruction presented with acute, painless, vision loss. Examination revealed no light perception vision. MRI of the orbits demonstrated new restricted diffusion of the right optic nerve on diffusion-weighted imaging and apparent diffusion coefficient sequences, consistent with posterior ischemic optic neuropathy. This is the first among cases of cocaine-induced optic neuropathy in the literature to illustrate ischemic changes on MRI in the optic nerve, highlighting the utility of diffusion-weighted imaging/apparent diffusion coefficient sequences when optic neuropathy is suspected and further suggesting an underlying ischemic etiology in similar cases.

Histopathologic alterations in the eyelid after Hughes tarsoconjunctival flap: loss of Meibomian glands with preservation of accessory lacrimal glands.

A 71-year-old female with invasive squamous cell carcinoma of the lower eyelid involving the ocular surface underwent surgical excision with negative margins and a subsequent reconstruction. The posterior lamellar defect was reconstructed with a Hughes tarsoconjunctival flap, and the anterior lamellar defect was reconstructed by advancing the lower eyelid skin. Three years later, the patient presented with signs suspicious for recurrence involving the tarsoconjunctival graft: a nodule along the mucocutaneus junction, symblepharon, and forniceal shortening. Repeat scouting biopsies showed variable degrees of moderate to severe squamous dysplasia so the patient underwent a staged full thickness excision of the lower eyelid and involved conjunctiva followed by reconstruction. Direct immunofluorescence was not diagnostic for ocular cicatrcial pemphigoid. Permanent histopathologic sections did not show any carcinoma, but the full thickness excisions involving the prior Hughes tarsoconjunctival flap highlighted two notable alterations: the Meibomian glands were absent and the accessory lacrimal glands of Wolfring were transposed to the mucocutaneous junction of the reconstructed lower eyelid.

Bacterial dacryoadenitis: clinical features, microbiology, and management of 45 cases, with a recent uptick in incidence.

PURPOSE: To review the clinical features, microbiology, management, and incidence of bacterial dacryoadenitis at our institution. METHODS: This was a case series examining patients with bacterial dacryoadenitis from 2004 to 2020. Charts were reviewed for demographics, comorbidities, presenting symptoms and signs, radiology, microbiology, and management. Main outcomes included need for surgical intervention or inpatient admission. RESULTS: Forty-five patients with bacterial dacryoadenitis had a mean age of 46.1 years. Presenting symptoms included eyelid edema (100%), extraocular motility restriction (53.3%), and purulent discharge (75.5%). Based on computed tomography or magnetic resonance imaging, 9 (20.5%) patients presented with definite abscess and 15 (34%) presented with a phlegmon or early abscess. Eleven patients (24.4%) required surgical drainage. Twenty patients (44.4%) required admission, for an average stay of 4 days (range 2-8 days). Common organisms included Haemophilus influenzae, Streptococcus pneumoniae, and Staphylococcus aureus. Presence of an early abscess or phlegmon correlated with need for drainage (p < 0.01). Extraocular motility restriction correlated with need for drainage (p = 0.02) and admission (p = 0.05). The incidence of bacterial dacryoadenitis at our institution increased as a percentage of confirmed dacryoadenitis cases; from 2004 to 2010 the incidence was 0 to 9.1% per year, while from 2010 to 2019 the incidence ranged from 7.7 to 36.2%. In 2019, our institution had 17 cases (incidence 36.2%) of bacterial dacryoadenitis. CONCLUSIONS: Bacterial dacryoadenitis is a major cause of dacryoadenitis, and its incidence may be increasing. It can resolve with minimal complications if managed appropriately, although some patients may require surgical drainage or admission for intravenous antibiotics.

Bilateral enlargement of all extraocular muscles: a presenting ophthalmic sign of hematologic malignancy.

Hematologic malignancies such as leukemia and lymphoma can frequently present in the orbit; however, involvement of the extraocular muscles is rare. The authors report two cases of systemic hematologic malignancy presenting with bilateral extraocular muscle enlargement and associated compressive optic neuropathy (CON). Both patients experienced clinical and radiographic improvement of ocular and systemic manifestations of disease with prompt initiation of targeted chemotherapy. These cases highlight the importance of including hematologic malignancy in the differential diagnosis of atypical bilateral extraocular muscle enlargement.

Lacrimal Gland Intravascular Micrometastasis From a Human Papillomavirus-Driven Anorectal Squamous Cell Carcinoma With a Review of Metastatic Disease to the Lacrimal Gland.

PURPOSE: To document a unique case of anorectal squamous cell carcinoma that was metastatic to the microvasculature of the lacrimal gland in a patient with human immunodeficiency virus and to review previously reported cases of metastases to the lacrimal gland. METHODS: Both a retrospective chart review and comprehensive literature review were performed. The unusual histopathologic pattern of the current case was illustrated with immunohistochemical studies (CD31, D2-40, pancytokeratin, p16, and p63) and in situ hybridization studies for high-risk human papillomavirus types 16 and 18. RESULTS: The authors describe the first case of metastatic anorectal squamous cell carcinoma to the lacrimal gland. Only 24 cases of metastatic disease to the lacrimal gland have been reported, the majority from breast carcinomas. The metastasis did not form a macroscopic lesions, instead was composed of microscopic intravascular and intraparenchymal tumor deposits, a subtle phenomena. Immunohistochemistry confirmed the presence of the intravascular neoplastic cells. p16 served as a surrogate marker for human papillomavirus-associated squamous cell carcinoma and was confirmed with in situ hybridization for human papillomavirus 16 and 18. This testing, combined with the clinical history, defined the diagnosis and confirmed human papillomavirus as the tumor driver. CONCLUSIONS: Metastases to the lacrimal gland remain rare, but clinicians and pathologists alike must be attuned to the possibility of subtle microscopic foci of tumor as a pattern of metastasis in scenarios without a discrete mass-forming lesion, as this may portend a poor prognosis.

Eccrine poroma of the eyelid.

Clinical and histopathologic case of an eyelid eccrine poroma, a benign adnexal neoplasm rarely found on the periorbital skin.

PD-L1 and PD-L2 Expression Levels Are Low in Primary and Secondary Adenoid Cystic Carcinomas of the Orbit: Therapeutic Implications.

PURPOSE: To determine if there is a biologic rationale for using checkpoint inhibitor drugs targeting programmed cell death ligand 1 (PD-L1) and PD-L2 in the treatment of adenoid cystic carcinoma of the orbit. METHODS: Twenty-three cases of adenoid cystic carcinoma involving the orbit (13 primary lacrimal gland, 5 secondarily extending into the orbit, and 5 unspecified) were examined histopathologically. Immunohistochemistry for PD-L1, PD-L2, and CD8 was performed. Charts were reviewed for clinical correlations. RESULTS: Expression of PD-L1 and of PD-L2 was overall low in adenoid cystic carcinoma (mean expression 1.4 ± 0.9 of 5 for PD-L1, mean 0.83 ± 1.1 of 5 for PD-L2), and tumor-infiltrating CD8-positive T-lymphocytes were sparse (mean 1.1 ± 0.51 of 3). Only 13 of the 23 (57%) cases expressed PD-L1 as a combined positive score ≥1 of cells. No associations were found between expression levels of these markers and patient sex, tumor site of origin, Tumor, Node, Metastasis stage, or patient outcome. A significant association was observed between stromal PD-L1 expression and tumor histopathologic subtype (p = 0.05), and between tumor PD-L1 expression and prior exposure to radiation (p = 0.03). CONCLUSIONS: Checkpoint inhibitor drugs may have limited impact in the treatment and clinical course of orbital adenoid cystic carcinoma based on the low frequency of CD8 infiltrate and low expression of PD-L1 and PD-L2. Pretreatment with radiation, however, may improve tumor response to checkpoint inhibitor drugs.

Poor prognoses of open globe injuries with concomitant orbital fractures.

PURPOSE: Orbital trauma, particularly with open globe injury, can have a wide range of visual outcomes, which can be difficult to predict at presentation. Clinical features on presentation may provide insight into visual prognosis. We hypothesized that patients with open globe injuries and concomitant orbital fractures have poorer visual outcomes than patients without orbital fractures. METHODS: We reviewed the charts of 77 patients with isolated open globe injuries (OG) and 76 patients with open globe injuries and concomitant orbital fractures (OGOF). Multivariate regression analysis was performed to assess the relative influence of individual presenting historical and clinical features on visual outcome. RESULTS: OGOF patients were more likely to have sustained blunt trauma than a sharp, penetrating injury compared to OG patients. Ocular wound locations were more posterior and likely to involve multiple zones in OGOF compared to OG patients. Among OGOF patients, orbital floor fractures were the most common and roof fractures were the least common, but the latter was associated with presenting NLP vision and multiple zone involvement. The presence of an orbital fracture independently increased the odds of subsequent evisceration/enucleation (OR: 4.6, 95% CI 1.3-20.1, p = .0246) and NLP vision (OR: 6.81, 95% CI 2.42-21.85, p = .0005) when controlling for zone, mechanism of injury, uveal prolapse and demographic variables. CONCLUSIONS: The presence of an orbital fracture independently confers a worse visual and ocular prognosis in patients with open globe injuries. Patients with open globe injuries in this category should be appropriately counseled.

Orbital Nasal-Type Extranodal Natural Killer/T-Cell Lymphoma: An Ongoing Diagnostic Challenge Further Confounded by Small-Cell Predominance.

PURPOSE: To highlight the histopathologic diagnostic challenges of small-cell predominant extranodal nasal-type natural killer/T-cell lymphoma (ENTNKT) of the orbit. METHODS: Retrospective chart review and histopathologic study with immunohistochemistry and in situ hybridization of 3 cases. RESULTS: Three cases of ENTNKT presented to the Mass Eye and Ear emergency room as orbital cellulitis over 1 year. The first case was unusual in that there was a predominance of small cells, giving the ENTNKT the histopathologic appearance of a nonmalignant inflammatory process. This challenging case is juxtaposed alongside 2 other cases, which exhibited the more typical lymphomatous microscopic appearance. DISCUSSION: ENTNKT can extend into the orbit from the adjacent sinuses or rarely arise primarily in the orbit. A diagnosis is typically made with a biopsy. Occasionally, however, the histopathologic diagnosis can be elusive when a predominance of small lymphomatous cells that are virtually indistinguishable from non-neoplastic inflammatory cells is present. Demonstration of CD56 positivity by immunostaining and in situ hybridization for Epstein-Barr virus are essential in confirming the diagnosis. CONCLUSIONS: ENTNKT should be considered both in the clinical and histopathologic differential diagnoses of orbital infections and idiopathic inflammations (pseudotumor).

Small Benign Storiform Fibrous Tumor (Fibrous Histiocytoma) of the Conjunctival Substantia Propria in a Child: Review and Clarification of Biologic Behavior.

PURPOSE: A case of a small benign storiform fibrous tumor of the conjunctival substantia propria is described to clarify the category of fibrous histiocytoma. In addition, a comparison of the various spindle cell tumors of the conjunctival substantia propria is explored. METHODS: The patient underwent a complete tumor excision, and the specimen was analyzed by histopathologic and immunohistochemical investigations. RESULTS: A cellular mass, composed solely of spindle cells in a storiform pattern without a component of histiocytic cells, was found beneath an undisturbed nonkeratinizing squamous epithelium and was separated from the epithelium by a grenz zone of uninvolved collagen. The lesion was sharply demarcated but not encapsulated. The Masson trichrome stain revealed scant deposition of intercellular collagen. The reticulin stain displayed numerous and delicate wiry fibers between the tumor cells and encircling capillaries. The Alcian blue stain demonstrated faint positivity in the interstitium. Immunohistochemistry revealed positivity for vimentin, factor XIIIa, smooth muscle actin, CD10, and CD45. Negative stains were obtained for CD34, CD56, S100, desmin, and Ki67. CONCLUSIONS: The broad term of fibrous histiocytoma should be reserved for deep fibroblastic spindle cell tumors (e.g., those of the orbit) that display an aggressive behavior. More benign superficial spindle cell tumors of the dermis are now preferentially characterized as dermatofibromas. It is suggested that equally benign epibulbar tumors should no longer be designated as fibrous histiocytomas but rather as benign storiform fibrous tumors. Tumors completely composed of polygonal histiocytoid (epithelioid) cells that are CD34+ should be excluded from the benign storiform fibrous tumor category. Positive smooth muscle actin and factor XIIIa staining in conjunction with negative staining for CD34 and desmin in the current spindled tumor cells are findings consistent with those of cutaneous dermatofibromas. Both the epibulbar and dermal spindle cell lesions have displayed an indolent and nonaggressive behavior. Microscopically they contain a high proportion of dendrocytic stellate cells that are either factor XIIIa+ or XIIIa-. Given the anatomic differences between the dermis and conjunctiva, the term dermatofibroma is inappropriate for the current tumor; instead the term benign storiform fibrous tumor has been proposed for superficial tumors of the conjunctiva.

Ophthalmic Plastic Surgery in Patients 100 Years and Older.

PURPOSE: The centenarian population is growing and ophthalmic plastic surgeons are providing care to an increasing number of elderly patients. Outcomes of centenarians have not been previously studied in the ophthalmic plastic surgery literature. The goal of the current review was to examine the baseline characteristics, surgical problems, and outcomes of this select group of patients. METHODS: A retrospective chart review was performed. Patients who underwent ophthalmic plastic surgery at age 100 or older between January 2000 and June 2016 by a member of the New England Oculoplastics Society were included in the study. RESULTS: Fifteen patients met inclusion criteria. The majority (66%) were female. More than half (60%) presented with a surgical problem of an urgent nature. Most disorders involved the lacrimal system or eyelids, and many were the result of trauma or infection. There were no cases of orbital tumor or thyroid eye disease. There were no surgical or anesthesia-related complications. Most patients (80%) had no documented history of dementia, and only 1 was diabetic. Notably, 33% of patients presented with no light perception vision in at least 1 eye. CONCLUSIONS: Ophthalmic plastic surgery can be performed safely in select patients 100 years of age and older. Formal prospective studies are needed to improve surgical care in this group.

Osseous cavernous hemangioma of the superior orbital rim.

A 53-year-old male presented with a bony lesion over the superior orbital rim increasing in size over several months. CT imaging showed a circumscribed, osseous lesion involving the outer table of the right frontal bone and superior orbital rim with a honeycomb appearance. Anterior orbitotomy revealed an osseous lesion along the superior orbital rim with purple cavernous spaces. Histopathological examination demonstrated cavernous vascular channels with variably-sized lumens and variably-thickened vascular walls interspersed among bony trabeculae consistent with an osseous cavernous hemangioma.
