RESUMEN
Background: Nasolacrimal duct obstruction (NLDO) is an adverse effect of high dose radioactive iodine (RAI) therapy for thyroid carcinoma. There are currently no established preventive measures. This study assesses whether preservative free artificial tears (PFATs) can decrease the 131I sodium iodide (131I) activity in the tears of patients following RAI therapy for thyroid carcinoma, and potentially serve as a preventive measure for RAI-associated NLDO. Methods: This non-randomized prospective pilot clinical trial recruited contact-lens wearing patients undergoing RAI therapy for thyroid cancer to self-administer PFATs into the right eye for four days starting on the day of RAI ingestion. Left eyes were the controls. While wearing contacts, patients self-administered PFATs per the following-Day 1: every 15 minutes for 2 hours, then every 30 minutes until bedtime, day 2: every hour for at least 12 hours, day 3: four times a day, and day 4: two times a day. Contact lenses were changed daily, and all lenses were collected one week later. Levels of 131I activity were measured by a well counter, decay-corrected, and converted to units of becquerel. Statistical analyses were performed to compare the 131I activities of the experimental and control eyes. Results: Sixteen eyes of eight patients treated with an average of 145.7 mCi (range 108-159) of 131I for papillary thyroid cancer were included. On day 1, artificial tears decreased the geometric mean 131I activity by 26% in the experimental eyes (p = 0.008). Artificial tears also decreased the geometric mean area under the curve over four days by 23% (p = 0.002). Conclusions: 131I is present in the tears following RAI therapy for thyroid carcinoma. Frequent PFATs starting on the day of RAI ingestion may decrease the level of 131I in the tears. This finding could have implications for lowering the risk of NLDO. Future multi-center clinical trials are needed to determine whether the use of artificial tears after RAI therapy may decrease the risk of NLDO. Clinical Trial Registration: NCT04327999.

Sebaceous carcinoma is a known mimicker of benign conditions, leading to frequent delays in diagnosis and proper treatment. We present two patients with chronic cicatrizing conjunctivitis initially diagnosed as ocular mucous membrane pemphigoid (MMP) and later found to have sebaceous carcinoma. Both patients presented with unilateral conjunctivitis that failed to improve with topical and systemic therapy, eventually developing fornix foreshortening and extensive symblepharon. Case 1 was diagnosed with ocular MMP based on clinical features alone, while Case 2 was diagnosed with biopsy-negative disease. Months to years later, both patients developed lid lesions found to be sebaceous carcinoma and underwent exenteration. As diagnosis and treatment of ocular MMP without positive direct immunofluorescence testing becomes increasingly accepted, clinicians should consider sebaceous carcinoma as the initial diagnosis or as a developing phenomenon during immunosuppression in the setting of chronic inflammation. A low threshold for repeat biopsy should be maintained.

OBJECTIVE: To identify factors associated with radioactive iodine (RAI)-acquired nasolacrimal duct obstruction (NLDO). METHODS: Retrospective chart review and telephone surveys of patients who received RAI therapy for thyroid carcinoma at an academic institution were conducted. Telephone surveys were used to screen for post-RAI NLDO diagnoses. Databases were reviewed for documented NLDO, demographics, RAI dose, total number of RAI treatments, and sialadenitis. Routine post-RAI whole-body scintigraphy (WBS) images were analyzed for the presence or absence of 131I sodium iodide (I-131) in the nasolacrimal duct. Intranasal I-131 activity was graded as none, low, moderate, and high; those with moderate or high activity were considered to have "increased" activity. Logistic and ordinal logistic regression models were used to evaluate the associations with NLDO while adjusting for I-131 dose. RESULTS: Of the 209 patients who completed the survey, 15 (7%) had NLDO diagnoses. Increased intranasal I-131 activity on WBS, presence of nasolacrimal I-131 WBS activity, presence of documented post-RAI sialadenitis, and history of >1 RAI treatment were associated with the development of NLDO from univariate analyses (P ≤ .013). After adjusting for the administered dose of I-131, the presence of sialadenitis and nasolacrimal I-131 activity on WBS were the remaining 2 factors significantly associated with NLDO development (P < .001 and P = .01, respectively). CONCLUSIONS: The presence of sialadenitis and nasolacrimal I-131 activity on WBS are I-131 dose-independent correlative factors for RAI-associated NLDO. Patients with these characteristics should be counseled on their increased risk of NLDO after RAI therapy for thyroid carcinoma.

PURPOSE: To report a case of orbital rhabdomyosarcoma and highlight the treatment approach to the dilemma of a residual mass. OBSERVATIONS: An eleven-year-old boy was diagnosed with Stage 1, Group III embryonal rhabdomyosarcoma in the orbit. After completing a 24-week treatment regimen of chemotherapy and radiation, imaging showed a large persistent mass with erosion through the medial wall. It was uncertain whether the erosion was due to radiation osteonecrosis or to advancing tumor, creating a treatment dilemma for the providers. A repeat biopsy was planned. During the procedure, the mass was completely excised due to ease of removal, and the biopsy showed completely treated tumor. MRI surveillance at four years follow up showed that the patient remains tumor-free. CONCLUSIONS AND IMPORTANCE: Rhabdomyosarcoma was once a disease with a very poor outcome, but advances in imaging, chemotherapy, and radiation therapy have improved the prognosis of these patients. What was once a surgical disease treated with morbid resection is now predominantly a medical disease diagnosed with biopsy and treated with chemotherapy and radiation. However, such patients may have a residual mass after completing treatment. This situation presents a challenge, as it may not be clear whether the persistent mass is active tumor or treated tumor. This report describes the presentation and management of such a case in the orbit and demonstrates that a residual orbital mass may remain and represent completely treated tumor.
RESUMEN
PURPOSE: To review the current literature on the safety and efficacy of orbital radiation for the management of thyroid eye disease (TED). METHODS: A literature search was conducted last in February 2021 of the PubMed database to identify all articles published in the English language on original research that assessed the effect of orbital radiation on TED. The search identified 55 articles, and 18 met the inclusion criteria for this assessment. A panel methodologist then assigned a level of evidence rating for each study, and all of them were rated level III. RESULTS: Two large retrospective studies demonstrated the efficacy of radiation treatment, with or without corticosteroid use, in preventing or treating compressive optic neuropathy (CON). Three studies highlighted the role of orbital radiation therapy (RT) to facilitate the tapering of corticosteroids. Several other studies showed a possible role for RT to improve diplopia and soft tissue signs. CONCLUSIONS: Although no level I or level II evidence exists, the best available evidence suggests that orbital radiation, used with or without corticosteroids, is efficacious in preventing CON, improving motility restriction, and decreasing clinical activity in TED. Orbital radiation also may facilitate a corticosteroid taper. Together, these studies show that RT seems to modify the active phase of TED. Short-term risks of orbital radiation are minor, but long-term outcome data are lacking.

We present an unusual case of a patient who acquired a pansinusitis and orbital cellulitis with necrotizing features, subsequently developing scleritis, keratitis, and anterior uveitis. To date, there are no reported cases of the simultaneous involvement of these ocular structures from a pansinusitis. Our patient was urgently taken to the operating room for drainage of the abscesses within his sinuses and the orbit. Intraoperative cultures were positive for Parvimonas micra, an odontogenic anaerobic bacteria. He was additionally found to have a central retinal artery occlusion. He was treated with systemic and topical antibiotics as well as topical dilute hypochlorous acid. The mechanisms of virulence of P. micra, including its synergistic relationship with other bacteria, ability to bind plasminogen, and its expression of proteases, contributed to this diffuse infection.

PURPOSE: To review the published literature to determine the efficacy and safety of homeopathic agents or vitamins in reducing ecchymosis after oculofacial surgery or laser surgery. METHODS: A literature search was conducted in the PubMed database initially in December 2019 and updated in March 2020 to identify all studies in the English language literature on the use of homeopathic agents or vitamins in oculofacial procedures, including laser surgery. The search yielded 124 citations, and 11 articles met all inclusion criteria for this assessment. A panel methodologist then assigned a level of evidence rating for each study. Eleven studies met inclusion criteria; 9 were rated level I, and 2 were rated level III. RESULTS: The agents studied in the articles identified included oral or topical Arnica montana (AM), oral Melilotus extract, topical vitamin K oxide, and topical AM combined with Rhododendron tomentosum. Metrics to describe ecchymosis varied. In 7 controlled studies, perioperative AM provided no or negligible benefit versus placebo. In 2 studies, vitamin K cream was equivalent to placebo. One study of oral Melilotus extract had less ecchymosis compared with controls in paranasal and eyelid ecchymosis at postoperative day (POD) 7, but not at PODs 1 and 4. A lone cohort study of combined topical AM and R. tomentosum lacked objective metrics and adequate controls. No serious side effects from administration of homeopathic agents or vitamins were identified. CONCLUSIONS: The current literature does not support the use of AM, vitamin K oxide, R. tomentosum, or Melilotus extract for reducing ecchymosis after oculofacial surgery or pulsed dye laser surgery.

PURPOSE: To evaluate the frequency and clinical course of residual orbital masses on imaging studies after multimodality treatment for orbital rhabdomyosarcoma. DESIGN: Retrospective case series. METHODS: We reviewed records of patients with primary orbital rhabdomyosarcoma who underwent chemotherapy and radiotherapy after surgical biopsy or debulking at 4 US centers during 1998-2019. Demographics, histologic subtype, tumor response 12 weeks after chemotherapy initiation and after completion of all treatment, and imaging findings were analyzed. RESULTS: Thirty-two patients met inclusion criteria. Twenty-two were male, and 30 were younger than 18 years. Histologic subtype was embryonal in 22 patients, alveolar in 8, and mixed embryonal/alveolar in 2. Median follow-up time was 46 months (range, 4.9-199 months). Two patients died. Twenty-seven patients had reliable end-of-treatment imaging findings, of whom 9 had a residual mass. Three residual masses disappeared spontaneously (by 4, 32, and 53 months), 2 remained at last contact, at 2 and 7 years of follow-up, and 3 were excised; 1 progressed and underwent an exenteration. Complete response at 12 weeks was associated with complete response at the end of treatment (P < .001). Patients with T1 or T2 tumor at presentation were more likely to have complete response at last contact than were those with T3 or T4 tumor (P < .05). Biopsy type (incisional or excisional) was not associated with response to treatment at any time point. CONCLUSION: A residual orbital mass on imaging may be present after multimodality treatment in approximately one-third of patients. Resolution without biopsy or excision varied from months to years.

PURPOSE: To compare the presentation and outcomes of patients with orbital cellulitis requiring surgical intervention caused by the Group F Streptococcus (GFS) versus other bacteria. We hypothesize that patients with GFS infections have a more severe presentation and worse clinical outcomes compared to infections by other bacteria. METHODS: After Institutional Review Board approval at a large academic institutional center, 70 patients with culture-positive orbital cellulitis who required surgical intervention were identified. Clinical examinations before and after surgery as well as preoperative imaging with computed tomography and/or magnetic resonance imaging were reviewed. The study measures were preoperative and postoperative vision, motility, involved sinus disease, complications, and total hospital length of stay. Multiple imputation was used for missing data. Characteristics of patients were compared using Chi-square and Wilcoxon rank-sum. RESULTS: Nineteen patients (27%) had positive cultures for GFS and 51 patients (73%) had positive cultures for other bacterial species. There was no significant difference in visual acuity, motility, or inflammatory markers in patients with GFS compared to other patients. Patients with GFS were noted to have more sinus involvement on presentation compared to patients with other bacterial infections (P = 0.007). CONCLUSION: GFS associated orbital cellulitis is associated with significantly more sinus involvement, but has similar outcomes as orbital cellulitis from other bacterial species.
RESUMEN
PURPOSE: To describe the experience of 4 oculoplastic surgeons with porcine bladder matrix for periocular anterior lamella and donor site skin defects either as stand-alone treatment or in conjunction with other reconstructive procedures. The authors hypothesized that defect size and location influence the requirement for additional matrix treatments or ancillary procedures. METHODS: Following the Institutional Review Board approval, the authors conducted a retrospective review of 17 patients treated with porcine bladder matrix at 2 oculoplastic practices between 2016 and 2018. Powdered matrix was applied to the skin defect and overlaid with a matrix sheet. Subsequent rounds of matrix treatment or other reconstructive procedures were performed as necessary. Defect size and location were correlated to the number of ancillary matrix treatments or surgical procedures via univariate analysis. RESULTS: Twenty-five sites (21 primary and 4 donor) in 17 individuals (8-95 years, M = 58.8 years, 10 males) were treated with porcine bladder matrix. All wounds healed successfully. Additional matrix treatments were administered at 5 sites. Ancillary procedures were performed for 7 sites. Upper lid involvement and larger defect size tended to require additional ancillary procedures (p = 0.006), while lower eyelid and other periocular defects required fewer procedures (p < 0.001). CONCLUSION: Porcine bladder matrices are useful adjuncts to healing periocular anterior lamella defects in various settings. Such repairs are useful in nonsurgical candidates, but must take into account varying levels of complexity based on lesion location. Smaller defects are more conducive to application of matrices as stand-alone treatment, while larger or upper eyelid defects often require additional procedures.

PURPOSE: Periocular inverted papilloma (IP) is a rare, locally aggressive tumor with a propensity for recurrence and malignant transformation. Historically treated via wide excision, this study examines the characteristics and management of periocular IP, comparing those confined to the nasolacrimal system with those invading the orbit. METHODS: An Institutional Review Board-approved, Health Insurance Portability and Accountability Act-compliant retrospective, comparative case series was conducted in patients with IP of the orbit or nasolacrimal system across 15 clinical sites. RESULTS: Of 25 patients, 22 met inclusion criteria with 9 limited to the nasolacrimal system and 13 invading the orbit. Mean age was 60.4 years, 55% were women, all were unilateral. Mean follow-up was 48 months. Rates of smoking, dust and/or aerosol exposure, human papillomavirus (HPV) status, and inflammatory polyps were elevated compared to rates in the general population (45%, 18%, 18%, and 14%, respectively). Bony erosion on computed tomography scans was statistically significantly associated with orbit-invading IP (p = 0.002). Treatment involved all confined IP undergoing surgery alone while 39% of orbit-invading IP also received radiation therapy and/or chemotherapy (p = 0.054). Orbit-invading IP was more likely to be excised with wide margins than IP confined to the nasolacrimal system (85% vs. 22%, p = 0.007). Overall rates of malignancy, recurrence, and patient mortality from IP were found to be 27%, 23%, and 9%, respectively. CONCLUSIONS: IP invading the orbit typically requires aggressive therapy, while IP confined to the nasolacrimal system may be treated more conservatively. Using risk factors, characteristics, and outcomes, a treatment algorithm was created to guide management.

PURPOSE: To review the literature on the efficacy and safety of medical and surgical interventions for indirect traumatic optic neuropathy (TON), defined as injury to the nerve that occurs distal to the optic nerve head. METHODS: A literature search was conducted on October 22, 2019, and updated on April 8, 2020, in the PubMed database for English language original research that assessed the effect of various interventions for indirect TON. One hundred seventy-two articles were identified; 41 met the inclusion criteria outlined for assessment and were selected for full-text review and abstraction. On full-text review, a total of 32 studies met all of the study criteria and were included in the analysis. RESULTS: No study met criteria for level I evidence. Seven studies (1 level II study and 6 level III studies) explored corticosteroid therapy that did not have uniformly better outcomes than observation. Twenty studies (3 level II studies and 17 level III studies) assessed optic canal decompression and the use of corticosteroids. Although visual improvement was noted after decompression, studies that directly compared surgery with medical therapy did not report uniformly improved outcomes after decompression. Four studies (1 level II study and 3 level III studies) evaluated the use of erythropoietin. Although initial studies demonstrated benefit, a direct comparison of its use with observation and corticosteroids failed to confirm the usefulness of this medication. One study (level II) documented visual improvement with levodopa plus carbidopa. Complication rates were variable with all of these interventions. Pharmacologic interventions generally were associated with few complications, whereas optical canal decompression carried risks of serious side effects, including hemorrhages and cerebrospinal fluid leakage. CONCLUSIONS: Despite reports of visual improvement with corticosteroids, optic canal decompression, and medical therapy for indirect TON, the weight of published evidence does not demonstrate a consistent benefit for any of these interventions. In summary, no consensus exists from studies published to date on a preferred treatment for TON. Treatment strategies should be customized for each individual patient. More definitive treatment trials will be needed to identify optimal treatment strategies for indirect TON.

PURPOSE: To determine the efficacy and safety of sentinel lymph node biopsy (SLNB) in the management of eyelid and conjunctival malignancy. METHODS: A literature search was performed in August 2019 and January 2020 for articles published in English in the PubMed and Cochrane Library databases. This search yielded 151 articles that were reviewed for relevancy, of which 27 were deemed to have met the inclusion criteria for this assessment. The data from these articles were abstracted and the articles were rated for strength of evidence by the panel methodologist. RESULTS: All 27 studies were rated level III, and a total of 197 SLNBs were reported. Diagnoses included conjunctival and eyelid cutaneous melanoma (85 and 42 patients, respectively), sebaceous gland carcinoma (35 patients), squamous cell carcinoma (26 patients), Merkel cell carcinoma (6 patients), pigmented epithelioid melanocytoid tumor (1 patient), mucoepidermoid carcinoma (1 patient), and signet ring carcinoma (1 patient). Tracer was found in regional lymph nodes in 100% of patients in 21 of 27 articles and in 191 of 197 patients overall. The number of lymph nodes removed ranged from 1 to 16, with most ranging from 1 to 5. Tumor-positive lymph nodes were found in 33 of 197 patients (16.8%), prompting recommendations for adjuvant treatments. Survival data were reported for 16 of these patients, with follow-up periods ranging from 3 to 36 months (average, 12.7 months). Fourteen of 16 patients received adjuvant treatments. Nine were alive and well, 1 was alive with metastases, and 6 had died of metastatic disease (including 2 patients who declined additional treatment). False-negative SLNB results were reported in 5 articles involving 9 of 197 procedures (4.6%). Complications were documented in 7 of 27 articles and included transient facial nerve weakness, persistent blue dye staining of the conjunctiva, neck hematoma, and suture abscess. CONCLUSIONS: Sentinel lymph node biopsy is a promising procedure in patients with eyelid and conjunctival malignancy, and it is useful in identifying sentinel lymph nodes. However, at present, insufficient evidence exists showing that SLNB improves patient outcomes and survival. Recognition of microscopic metastatic disease may prove beneficial in staging and guiding adjuvant therapy.
