ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

PURPOSE: This study describes the clinical features and management of epiblepharon as a manifestation of thyroid eye disease (TED). In addition, we compare the frequency and age in Asian and non-Asian patients, and discuss pathophysiologic implications. DESIGN: Retrospective case-control study. METHODS: This is a single-center retrospective review that identified 172 adult patients (age 19 to 83) with TED that were consecutively evaluated by 1 author (T.J.M.) between December 2015 and July 2018. Diagnosis of TED and epiblepharon was based upon clinical assessment as documented in the medical record. RESULTS: In a cohort of 172 patients (mean age 52; 138 female), 3 patients with acquired epiblepharon were identified, all of whom were Asian. The proportion of affected Asian patients (3/of 17, 17.6%) was significantly higher than that of non-Asian patients (0/155, P < 0.001). Patients with epiblepharon were also significantly younger than those without epiblepharon, 29.7 ±â€Š2.1 versus 48.7 ±â€Š13 years of age (P = 0.026). All 3 patients underwent surgical correction with lateral canthoplasty and anterior lamellar pretarsal fixation with successful outcomes. CONCLUSIONS: Lower eyelid epiblepharon may occur in TED. In our clinic-based population, this finding was significantly more frequent in Asian patients and in younger patients. Relieving horizontal tension in conjunction with anterior lamella pretarsal fixation is an effective method of correcting TED-associated epiblepharon.

ABSTRACT

Thyroid associated orbitopathy (TAO) is a common diagnosis encountered by ophthalmologists and oculoplastic surgeons. TAO has a varying clinical presentation that can include upper eyelid retraction, restrictive strabismus, proptosis, exposure keratopathy, and optic neuropathy. In this review, we discuss the most recent literature on and the current understanding of the pathophysiology of TAO. We also review available and potential future treatment options for the management of TAO.

ABSTRACT

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.

ABSTRACT

Neurofibromatosis type 1 (NF1) is a relatively common multisystemic inherited disease and has been extensively studied by multiple disciplines. Although genetic testing and confirmation are available, NF1 remains a clinical diagnosis. Many manifestations of NF1 involve the eye and orbit, and the ophthalmologist, therefore, plays a significant role in the diagnosis and treatment of NF1 patients. Improvements in diagnostic and imaging instruments have provided new insight to study the ophthalmic manifestations of the disease. We provide a comprehensive and up-to-date overview of the ocular and orbital manifestations of NF1.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.
