Intravascular Large B-cell Lymphoma Diagnosed by Nasal Biopsy in a Patient Presenting with Bilateral Ptosis and Ophthalmoplegia.

Intravascular large B-cell lymphoma (IVLBCL) is a rare type of lymphoma, involving the lumen of predominantly small blood vessels, especially capillaries. The orbit is an uncommon site of involvement for IVLBCL, and diagnosis before autopsy is even more rare as most cases are established post-mortem. Herein, the authors describe a 73-year-old male who presented with 3 weeks of progressive bilateral ptosis and ophthalmoplegia. Computed tomography (CT) and subsequent magnetic resonance imaging (MRI) revealed diffuse abnormal thickening and enhancement of bilateral orbital apices, superior orbital fissures, and cavernous sinus, along with persistent focal opacification of the left frontal and ethmoid sinuses. Infectious and inflammatory workup of serum and cerebrospinal fluid was negative. Ethmoidal sinus and middle turbinate biopsy confirmed intravascular large B-cell lymphoma and the patient was started on R-CHOP chemotherapy regimen.

Bilateral Concurrent Endocrine Mucin-Producing Sweat Gland Carcinoma and Mucinous Carcinoma of the Eyelids.

Endocrine mucin-producing sweat gland carcinoma (EMPSGC) is thought to be a precursor to mucinous carcinoma, both of which are rare. In this case report, the authors present a 55-year-old woman with concurrent EMPSGC and mucinous carcinoma manifesting with 2 distinct lesions on her left upper and lower eyelid and 1 lesion on her right lower eyelid. Biopsy and immunohistochemical staining supported primary cutaneous origin of the tumors. Systemic metastatic workup was initiated and thus far negative. The patient underwent staged slow Mohs micrographic surgery to remove one tumor at a time, with delayed reconstruction. This is the first reported case of EMPSGC and mucinous carcinoma presenting as distinct lesions both bilaterally and synchronously.

Blue nevi of the palpebral conjunctiva: report of 2 cases and review of literature.

PURPOSE: To describe two patients with blue nevi of the palpebral conjunctiva and to review the existing literature on common and cellular blue nevi of the conjunctiva. METHODS: Report of two cases and literature review. RESULTS: We present two cases of blue nevi in the palpebral conjunctiva: an atypical cellular blue nevus of the left upper eyelid and a common blue nevus around the lacrimal punctum of the left lower eyelid. Both patients underwent full thickness eyelid excision with wide margins. There was no tumor recurrence at 11 and 4 months postoperatively. CONCLUSIONS: Blue nevi are a group of melanocytic tumors that rarely involve the ocular adnexa. They may arise in the palpebral conjunctiva and should be considered in the differential diagnosis of pigmented lesions in this location as they can mimic melanoma.

Orbital inflammation in the setting of a nylon foil implant.

A 61-year-old man underwent left medial wall and floor fracture repair with a Suprafoil® implant. He had postoperative orbital congestion and lower eyelid swelling that persisted for over seven weeks. Examination demonstrated hyperglobus with supraduction, infraduction, and adduction deficits. Imaging revealed a 3.7 × 3.6 × 2.6 cm isodensity along the implant, thought to be hematoma. The patient elected to pursue exploration and possible drainage. Intraoperatively, there was no hematoma; rather, we found a fibroinflammatory rind along the periorbita surrounding the implant. This was biopsied, and the implant was removed, as the fractures had sufficiently healed. Pathology showed dense fibroconnective tissue with associated inflammation. The patient completed a steroid taper with improvement in all symptoms and resolution of diplopia. To our knowledge, this is the first reported case of such a prominent orbital inflammatory reaction to nylon foil, a departure from the delayed hematic cysts typically associated with these implants.

Tarsal Epithelial Cysts: Prevalence, Case Series, and Synthesis of Existing Literature.

PURPOSE: Tarsal epithelial cysts (TECs) are squamous epithelial-lined lesions of the eyelid that are often mistaken for chalazia or epidermal inclusion cysts. They remain poorly described in the literature. This study is designed to characterize the prevalence and clinical features of TEC. METHODS: We conducted a single-center retrospective review of adult patients with a diagnosis of eyelid neoplasm, eyelid cyst, hordeolum, stye, or chalazion between January 1, 2011 and July 1, 2017. Among this cohort, we identified patients with a histopathologic diagnosis of TEC. We also conducted a PubMed literature review and synthesis of existing clinical data of patients reported to have TEC, noting common clinical and histopathological features. RESULTS: Of 7,516 patients, we identified 6 patients with a histopathological diagnosis of TEC, amounting to a prevalence of 0.08% amongst patients with eyelid lesions. Average age was 49.7 years (range 18-76 years), with a 1:1 male to female ratio. The most common presenting symptom was a painless eyelid mass, and the majority (66.6%) had a preoperative diagnosis of chalazion. All but 1 patient had surgical excision from the posterior approach and there was 1 recurrence in the follow-up period. On review of the literature, we identified 68 prior cases of TEC from 18 clinical studies, with clinical features mirroring our case series. CONCLUSIONS: TEC has stereotypical clinical and histologic features that distinguish it from other tarsal lesions. Our review identified TEC as a relatively rare cause of eyelid lesions.

Pituitary Adenoma Apoplexy of the Orbit, Diagnosis, and Management With Presurgical Embolization.

Orbital invasion of pituitary adenomas has been previously reported. In this report, the authors describe a 71-year-old female with a prolactinoma that presented with invasion of and apoplexy within the orbit. The patient underwent exenteration, followed by rapid tumor recurrence and growth. Given the hemorrhagic nature of the tumor, she subsequently underwent preoperative embolization and surgical resection. This case is notable in that it illustrates both apoplexy of a pituitary tumor within the orbit and the benefit of presurgical embolization.

Ophthalmic manifestations of tuberous sclerosis: a review.

Tuberous sclerosis or tuberous sclerosis complex (TSC), one of the phakomatoses, is characterized by hamartomas of the heart, kidney, brain, skin and eyes. Ophthalmologic examinations are required in all cases of TSC. Retinal hamartomas are the most common ocular finding in tuberous sclerosis. The majority of hamartomas are non-progressive; however, lesions with subretinal fluid and progression have been reported. This paper details the genetics, clinical features and ocular findings of TSC and reviews potential therapeutic options for ophthalmic manifestations.

Economic and Quality of Life Benefits of Anti-VEGF Therapy.

Vision impairment and blindness create a significant impact on quality of life and loss of productivity. Health care expenditures for vision problems, including direct medical costs and indirect costs for support services and loss of productivity, amount to $139 billion annually. It is projected that by 2020, five million people will have visual impairment due to age related macular degeneration and diabetic macular edema. VEGF inhibitor therapy has been shown to be a cost-effective treatment for age related macular degeneration and diabetic macular edema that has reduced the incidence of vision loss and can reduce the associated economic and societal cost.

Chemodenervation of extraocular muscles with botulinum toxin in thyroid eye disease.

BACKGROUND: Thyroid eye disease (TED) presents a management dilemma for strabismologists due to the variability of its clinical course. Prisms may be prescribed to relieve diplopia in small deviations. Surgical intervention, on the other hand, should not be done until the active phase of the disease has subsided. We report our experience with chemodenervation utilizing botulinum toxin (BT) injection in the management of TED-related strabismus. METHODS: A retrospective chart review was done on twenty-two (22) consecutive patients receiving BT injections at the University of California, San Diego (UCSD) Thyroid Eye Center. All BT injections were administered by a single physician under electromyographic guidance. RESULTS: The clinical records of 22 patients (18 females) were reviewed. Seven patients (32 %) had a reduction of their deviation to a point where surgery was not required. In six patients (27 %), surgery was required but an improvement in ocular deviation was found, altering the original surgical plan. In four patients (18 %), the deviation continued to progress after BT injection. Success rates were higher if pre-treatment deviation was less than 20 prism diopters ((∆)). CONCLUSION: One third of the chemodenervation-treated patients avoided surgical intervention, with an additional 27 % (total of 40 % of those who needed surgery) having a reduced deviation prior to surgery. Using BT injection to extraocular muscles to treat diplopia in TED patients is most effective in preventing surgery in those patients with 20(∆) or less of deviation.

Outcomes of endonasal dacryocystorhinostomy without mucosal flap preservation.

PURPOSE: Dacryocystorhinostomy (DCR) is the standard procedure for the treatment of acquired nasolacrimal duct obstruction (NLDO) that can be performed through an external or endonasal approach. Both techniques create a fistula from the lacrimal sac into the nasal cavity via a bony osteotomy. Historically, external DCR has been considered the gold standard; however, recent reports suggest endonasal DCR is an effective alternative. There are numerous variations of endonasal DCR described in the literature that report variable success rates. The purpose of this study is to describe the approach and success rate with endonasal DCR in which nasal mucosa, bone, and lacrimal sac mucosa are sequentially removed. METHODS: The authors retrospectively reviewed cases of endonasal DCR from 2004 to 2011 from 2 institutions (the University of California, San Diego, California, and the Fante Eye and Face Center in Denver, Colorado, U.S.A.). Patients with a history of epiphora and NLDO confirmed with punctal irrigation were included. Exclusion criteria were the presence of canalicular obstruction, history of orbital trauma, and prior DCR surgery. Success was defined as subjective relief of epiphora and confirmation of ostium patency with irrigation. RESULTS: A total of 324 patients (74 men, 250 women; mean age 59.3) encompassing 407 endonasal DCR cases were included in the study. The total case success rate was 92.2% with an average follow-up time of 91.5 days. Revision surgery was performed in 7 of the failed cases and resulted in success in 6 of these cases. CONCLUSIONS: Endonasal DCR is a simple and effective approach to surgically treat NLDO and offers success rates comparable with external DCR.

Bilateral squamous cell carcinoma of the lacrimal sac.

A 42-year-old man presented with right-sided epiphora, a fleshy lesion emanating from the right inferior punctum and a painless mass below the medial canthal tendon. Biopsy of the lacrimal sac mass disclosed papillary squamous cell carcinoma in situ. The patient underwent wide local excision with clear surgical margins and remained disease free until 28 months later when he returned with hemorrhagic epiphora of the OS and fullness overlying the left lacrimal sac. Biopsy confirmed papillary squamous cell carcinoma in situ. He underwent similar excision and has remained disease free for 6 months. To the best of the authors' knowledge, this is the first report of bilateral squamous cell carcinoma of the lacrimal sac.

Current Guidelines and Opinions in the Management of Orbital Floor Fractures.

Orbital floor fractures are a common manifestation of facial trauma that is encountered by ophthalmology, otolaryngology, and oral maxillofacial specialists. Surgical intervention is required emergently in cases of tissue entrapment and less urgently in cases of presenting with persistent diplopia, enophthalmos greater than 2 mm, and/or fractures involving greater than 50% of the orbital floor. Surgical management is a debated topic with differing opinions among surgeons regarding timing of repair, type of implant, and surgical approach.

Progression of Subperiosteal Orbital Abscess after Clinical Resolution on Intravenous Antibiotics and Steroids.

We present a case of a 7-year-old boy who was presented with a small medial subperiosteal orbital abscess (SPOA) and trace superior phlegmon and who was initially treated with intravenous (IV) antibiotics, corticosteroids, and observation. After clinical resolution and discharge, the patient returned with superior migration of his abscess requiring surgical drainage. Potential factors leading to readmission are discussed, including the anti-inflammatory and immunosuppressant effects of steroids, and presence of early surgical indictors such as bony dehiscence and proptosis. This case highlights the need for careful consideration of initial imaging and presence of a non-medial phlegmon prior to initiation of steroids.

OphthoPods: An Analysis of the Educational Content and Changes of Ophthalmology Podcasts.

Objective Podcasts are a novel modality for digitally disseminating ophthalmic knowledge, yet minimal information exists on their offerings. This study sought to describe the growth of ophthalmology podcasts, characterize their features, and analyze clinically pertinent content trends. Materials and Methods Apple Podcasts, Spotify, Google Podcasts, and Google Search were queried for English- language shows relating primarily to ophthalmology. Ninety-six podcasts and 3,594 episodes were analyzed. Results Of the 48 currently active shows, most cover general ophthalmology topics ( n = 25, 52.1%) and are run by multiple hosts ( n = 29, 60.4%) in both academics and private practice. The majority of podcasts released episodes monthly ( n = 21, 21.9%) or less frequently than monthly ( n = 36, 37.5%). Among all episodes, procedural topics ( n = 951 episodes, 26.4%) and clinical education ( n = 1385, 38.5%) were the most prevalent categories. Retina was the most represented subspecialty in podcast production, while oculoplastics and neuro-ophthalmology had the fewest podcasts. Episodes on disease pathophysiology ( p = 0.04) and published research ( p < 0.001) each declined over time. The proportion of episodes released from 2020 to 2022 that discussed digital technologies was 33.3% greater versus 2005 to 2019 ( p = 0.005). Personal retrospective episodes doubled, career guidance and patient perspectives tripled, and wellness and social justice topics increased fivefold (all p < 0.001). Conclusion In summary, the coronavirus disease 2019 pandemic coincided with a rise in ophthalmology podcasts and shifts in content. Podcasts have trended toward practical advice and technologies, reflecting their value in sharing modern, peer-to-peer pearls. Emphases on storytelling and social justice offer unique, clinically relevant perspectives compared with traditional modalities.

The association of race with thyroid eye disease presentation and outcomes.

Introduction: Classification of thyroid eye disease (TED) is largely based on guidelines developed in Europe and North America. Few studies have investigated the presentation and treatment of TED in Black populations. The objective is to examine the manifestations of TED in secondary and tertiary care center-based populations with a significant proportion of Black patients. Materials and methods: Retrospective chart review identifying patients with a reported race/ethnicity and a presenting clinical diagnosis of TED at Kings County Hospital and SUNY Downstate Medical Center and affiliated clinics from January 1, 2010 through July 31, 2021. Main outcome measures include age of disease onset, sex, smoking status, insurance status, postal code of residence, clinical exam features, number of follow-up visits, length of follow-up, and treatments received. Results: Of the 80 patients analyzed, 49 were Black (61.2%) and 31 were White (38.8%). Between Black and White patients, there were differences in the mean age of presentation (48.1 [range 21-76] vs 56.8 [range 28-87] years, P=0.03), insurance status (51.0% vs 77.4% private insurance, P=0.02), and mean follow up length among those with multiple visits (21.6 [range 2-88] vs 9.7 [range 1-48] months, P=0.02). The distribution of EUGOGO scores were not significantly different between Black and White patients. On initial presentation, fewer Black patients had chemosis (OR 0.21, 95% CI, 0.08 to 0.57, P=0.002), and caruncular swelling (OR 0.19, 95% CI, 0.06 to 0.59, P=0.002) compared to White patients. During the overall disease course, fewer Black patients had subjective diplopia (OR 0.20, 95% CI, 0.07 to 0.56, P=0.002), chemosis (OR 0.24, 95% CI, 0.09 to 0.63, P=0.004), and caruncular swelling (OR 0.18, 95% CI, 0.07 to 0.51, P=0.001) compared to White patients. Black patients received oral steroids (42.9% vs 67.7%, P=0.03), intravenous steroids (18.4% vs 16.1%, P=0.8), orbital decompression surgery (16.7% vs 6.5%, P=0.19), and teprotumumab (22.9% vs 22.6%, P=0.99) at similar rates. Discussion: Black patients presented with fewer external exam findings suggestive of active TED compared to White patients, but the rate of compressive optic neuropathy and decompression surgery were similar in the two groups. These differences may be due to disease phenotypes, which warrant further study.

Utility of diffusion-weighted imaging to differentiate benign and malignant solid orbital tumours.

OBJECTIVE: We assessed the utility of apparent diffusion coefficients (ADCs) derived from diffusion-weighted imaging to differentiate benign and malignant orbital tumours by oculoplastic surgeons in the clinical setting and sought to validate observed ADC cut-off values. DESIGN AND PARTICIPANTS: Retrospective review of patients with benign or malignant biopsy-confirmed orbital tumours. METHODS: Blinded graders including 2 oculoplastic surgeons, 1 neuroradiologist, and 1 medical student located and measured orbital tumour ADCs (10-6 mm2/s) using the Region of Interest tool. OUTCOME MEASURES: Nonradiologist measurements were compared with each other to assess reliability and with an expert neuroradiologist measurement and final pathology to assess accuracy. RESULTS: Twenty-nine orbital tumours met inclusion criteria, consisting of 6 benign tumours and 23 malignant tumours. Mean ADC values for benign orbital tumours were 1430.59 ± 254.81 and 798.68 ± 309.12 mm2/s for malignant tumours. Our calculated optimized ADC cut-off to differentiate benign from malignant orbital tumours was 1120.84 × 10-6 mm2/s (sensitivity 1, specificity 0.9). Inter-rater reliability was excellent (intraclass correlation coefficient = 0.92; 95% CI, 0.86-0.96). Our 3 graders had a combined accuracy of 84.5% (92.3%, 92.3%, and 65.4%). CONCLUSIONS: Our ADC cut-off of 1120.84 × 10-6 mm2/s for benign and malignant orbital tumours agrees with previously established values in literature. Without priming with instructions, training, or access to patient characteristics, most tumours were correctly classified using rapid ADC measurements. Surgeons without radiologic expertise can use the ADC tool to quickly risk stratify orbital tumours during clinic visits to guide patient expectations and further work-up.

Bilateral Cavernous Sinus Thrombosis in Presumed COVID-19 Infection.

Cavernous sinus thrombosis (CST) is a rare life-threatening condition where a blood clot develops within the cavernous sinus secondary to various etiologies, ranging from infection to aseptic causes (e.g., trauma or surgery). The dural sinuses and the cerebral veins have no valves, which allow retrograde blood flow according to pressure gradients. As a result, cavernous sinuses are vulnerable to septic thrombosis from infection at various sites including sphenoid and ethmoid sinuses. Less commonly, infections of the face, ears, nose, tonsils, soft palate, and teeth may lead to CST if treatment is delayed. Clinical findings of CST extending to the opposite cavernous sinus typically requires 24-48 hours after the initial presentation of orbital signs. However, we present a patient with facial and orbital cellulitis that was immediately treated with high-dose IV antibiotics within one hour of presentation and IV heparin six hours after admission and CST diagnosis. However, the patient developed a rapid progression of bilateral CST within six hours, unresponsive to treatment. Although facial cellulitis may lead to septic CST if untreated, the rapid progression of bilateral CST in the setting of acute hypoxic respiratory failure, renal failure, and coagulation abnormalities suggests a possible underlying infection and complications similar to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Case Report: Cavernous Sinus Syndrome as the Initial Presentation of Multiple Myeloma.

Multiple myeloma (MM) is the second most common hematologic malignancy and most common primary bone malignancy. Ocular manifestations of MM are extremely rare and may be the first presentation leading to diagnosis. Ophthalmologists routinely encounter cavernous sinus syndrome, and there is a wide range of possible etiologies. Here, we present a case of a patient presenting with diplopia, ptosis, and ophthalmoplegia found to have a cavernous sinus plasmacytoma with systemic workup consistent with MM. MM is a rare cause of cavernous sinus syndrome and should be considered in the setting of a skull base mass.
