IgG4-related Orbital Disease Presenting as an Orbital Apex Lesion.

IgG4-related disease is an uncommon multisystem inflammatory disease characterized by tissue infiltration by IgG4 plasma cells, extensive fibrosis, and sclerosing inflammation. Diffuse orbital involvement extending to the orbital apex and cavernous sinus has been reported, but a solitary well-circumscribed lesion at the apex has not been previously reported. Herein, we report a unique case of IgG4-related orbital disease presenting as a solitary well-circumscribed orbital apex lesion causing subacute visual decline in a 45-year-old male. MRI demonstrated bilateral lacrimal gland and infraorbital nerve enlargement and an 18 × 7 mm left orbital apex lesion demonstrating homogeneous contrast enhancement and isointense signal on T2. He was initially treated with tapering systemic corticosteroid therapy with improvement in his vision; however, he experienced visual deterioration 3 months later with recurrent inflammation. He subsequently commenced high-dose systemic corticosteroid therapy and rituximab infusions with improvement of left visual acuity to 6/7.5 + 2.

Transcutaneous retrobulbar amphotericin B for rhino-orbital-cerebral mucormycosis: a multi-center retrospective comparative study.

PURPOSE: To assess whether transcutaneous retrobulbar amphotericin B injections (TRAMB) reduce exenteration rate without increasing mortality in rhino-orbital-cerebral mucormycosis (ROCM). METHODS: In this retrospective case-control study, 46 patients (51 eyes) with biopsy-proven ROCM were evaluated at 9 tertiary care institutions from 1998 to 2021. Patients were stratified by radiographic evidence of local orbital versus extensive involvement at presentation. Extensive involvement was defined by MRI or CT evidence of abnormal or loss of contrast enhancement of the orbital apex with or without cavernous sinus, bilateral orbital, or intracranial extension. Cases (+TRAMB) received TRAMB as adjunctive therapy while controls (-TRAMB) did not. Patient survival, globe survival, and vision/motility loss were compared between +TRAMB and -TRAMB groups. A generalized linear mixed effects model including demographic and clinical covariates was used to evaluate the impact of TRAMB on orbital exenteration and disease-specific mortality. RESULTS: Among eyes with local orbital involvement, exenteration was significantly lower in the +TRAMB group (1/8) versus -TRAMB (8/14) (p = 0.04). No significant difference in mortality was observed between the ±TRAMB groups. Among eyes with extensive involvement, there was no significant difference in exenteration or mortality rates between the ±TRAMB groups. Across all eyes, the number of TRAMB injections correlated with a statistically significant decreased rate of exenteration (p = 0.048); there was no correlation with mortality. CONCLUSIONS: Patients with ROCM with local orbital involvement treated with adjunctive TRAMB demonstrated a lower exenteration rate and no increased risk of mortality. For extensive involvement, adjunctive TRAMB does not improve or worsen these outcomes.

Survival benefit of exenteration in COVID-19-associated rhino-orbital mucormycosis.

PURPOSE: There has been a sudden increase in the number of rhino-orbital mucormycosis cases, primarily affecting patients recovering from COVID-19 infection. The local health authorities have declared the current situation an epidemic. In this study, we assess the role of exenteration in preventing disease progression and improving survival in patients with rhino-orbital mucormycosis. METHODS: The patients undergoing exenteration were grouped into the exenteration arm and those denying exenteration were grouped into the nonexenteration arm. The patients were followed at 1 month and 3 months. The 6-month survival data were collected telephonically. Continuous data were presented as Mean ± SD/Median (IQR) depending on the normality distribution of data, whereas the frequency with percentages was used to present the categorical variables. Kaplan-Meier survival curves were created to estimate the difference in survival of patients with exenteration in rhino-orbital mucormycosis versus those without exenteration. RESULTS: A total of 14 patients were recruited for our study based on the inclusion and exclusion criteria. All the patients were qualified for exenteration; however, only eight patients underwent exenteration and six patients did not consent to exenteration. At the end of 3 months in the exenteration group, four (50%) patients died. Two patients died within a week of exenteration, whereas two patients died after 2 weeks of exenteration. The deaths in the first week were attributed to septic shock and the deaths happening beyond 2 weeks were attributed to severe meningitis. The Kaplan-Meier survival analysis showed the cumulative probability of being alive at 1 month in the exenteration arm to be 85%, and it decreased to 67% by 53 days and subsequently remained stable until the end of 3 months. CONCLUSION: The Kaplan-Meier survival analysis did not show a survival benefit of exenteration at 3 months and 6 months in COVID-associated rhino-orbital mucormycosis.

A case report on clinical features, diagnosis, and treatment of rhino-orbito-cerebral mucormycosis.

BACKGROUND: Rhino-orbito-cerebral mucormycosis (ROCM) is an opportunistic pathogenic fungal disease caused by the fungus mucor, and it is a life-threatening fungal infection. The ulceration on the skin of the head and neck, accompanied by rhinitis, headache, orbital inflammation, and eyelid edema, should raise a high suspicion of Mucor infection in diabetic patients with inadequately controlled blood glucose. CASE DESCRIPTION: The clinical data of a patient with ROCM were analyzed retrospectively, and the clinical features were analyzed. The patient was admitted to the hospital with "diabetic hyperosmotic coma" after presenting with fatigue, poor appetite, and disturbances in consciousness as initial symptoms. After improving relevant examinations, controlling underlying diseases, and administering antifungal treatment, the final clinical outcome was death. CONCLUSION: ROCM is more prevalent in patients with uncontrolled diabetes and varied clinical manifestations. The characteristic feature is an eschar-like necrosis of the local skin or mucosa. The gold criteria for diagnosis are pathology and fungal culture; imaging examination does not reveal any specific manifestations. Early diagnosis and effective treatment are the keys.

Case Report: Three-Day Albendazole Regimen for Orbital Cysticercosis and the Stardust Sign.

Ultrasonography findings have been used to diagnose and treat 10 cases of orbital cysticercosis. Although oral prednisolone has a key role in symptomatic alleviation, 3-day albendazole has been demonstrated to be curative without any recurrence.

Local injection of amphotericin B: novel use in the treatment of fungal maxillary sinusitis.

This report highlights the role of local amphotericin B (AMB) injection in cases of maxillary mucormycosis. The COVID-19 pandemic has resulted in a dramatic rise in the number of rhino-orbital mucormycosis cases. Although extensive surgical debridement remains the gold standard treatment, tissue salvage is desirable. The cases of two patients treated with local AMB are reported here, indicating that early intervention for maxillary fungal sinusitis in the form of local AMB may avoid the need for more invasive treatment.

Overwhelming orbital cellulitis in a neonate.

This article discusses a rare ophthalmic manifestation of neonatal bacterial infection and its management, including surgical drainage. The case discussed is that of a neonate who presented with rapidly progressing ophthalmic symptoms suggestive of orbital cellulitis. The neonate also had extensive intracranial involvement and had spread to contiguous structures causing a temporal lobe abscess. As there was no local injury, a haematogenous spread was strongly considered. With blood culture and pus culture yielding the growth of Staphylococcus aureus, systemic antibiotics and surgical interventions were required to successfully manage the neonate. Through this case report, we emphasise that orbital infections are grave in neonates and may culminate into devastating intracranial complications; hence, it necessitates appropriate medical and surgical interventions right from hospital admission.

Short intravenous amphotericin B followed by oral posaconazole using a simple, stratified treatment approach for diabetes or COVID-19-associated rhino-orbito-cerebral mucormycosis: a prospective cohort study.

OBJECTIVES: To evaluate the efficacy and safety of short-course intravenous amphotericin B followed by sustained release posaconazole tablets for diabetes or COVID-19-associated rhino-orbito-cerebral mucormycosis. METHODS: This prospective, pragmatic study included adults with diabetes or COVID-19-associated rhino-orbito-cerebral mucormycosis. Patients received short (7-14 days) or long (15-28 days) intravenous antifungal therapy (short intravenous antifungal treatment [SHIFT] or long intravenous antifungal treatment [LIFT], respectively) depending on the presence or absence of brain involvement. All patients received step-down posaconazole tablets, debridement, and glycemic control. The primary outcome was the treatment success at week 14, which was determined by assessing survival and the absence of disease progression through clinical evaluation and nasal endoscopy. Log-binomial regression analysis (risk ratio and 95% CI) was performed to assess factors associated with the primary outcome. RESULTS: Intravenous therapy was administered to 251 participants: SHIFT, 205 (median duration, 13 days); LIFT, 46 (median duration, 22 days). Treatment success at 3 months was 88% (217/248; 95% CI, 83-91%): SHIFT group, 93% (189/203; 89-96%); LIFT group, 62% (28/45; 47-76%). All-cause mortality was 12% (30/251): SHIFT group, 6% (13/205); LIFT group, 37% (17/46). Age (aRR [95% CI]: 1.02 [1.00-1.05]; p 0.027), diabetic ketoacidosis at presentation (2.32 [1.20-4.46]; p 0·012), glycated haemoglobin A1c (1.19 [1.03-1.39]; p 0.019), stroke (3.93 [1.94-7.95]; p 0·0001), and brain involvement (5.67 [3.05-10.54]; p < 0.0001) were independently associated with unsuccessful outcomes. DISCUSSION: Short intravenous amphotericin B with step-down posaconazole tablets should be further studied as primary treatment option for diabetes or COVID-19-associated mucormycosis in randomized controlled trials.

Acute-Onset Orbital Inflammation in a Patient With Multiple Myeloma.

A 72-year-old man had right-eye conjunctival injection, chemosis, eyelid edema, and pain with eye movements. Examination showed visual acuity of 20/50, reduced ocular motility in all gazes, proptosis, and chemosis. Treatment with vancomycin and ceftriaxone and ampicillin-sulbactam was followed by symptom worsening. What would you do next?

Long-term outcomes of transcutaneous retrobulbar amphotericin B in COVID-19-associated mucormycosis.

Purpose: To describe the long-term outcomes of transcutaneous retrobulbar amphotericin B (TRAMB) in COVID-19-associated mucormycosis. Methods: In total, 18 cases of COVID-19-associated mucormycosis were reviewed. In addition to the recommended treatment protocol, all patients were to be given 3.5 mg/ml/day of TRAMB for five days. Results: Of the 18 patients, 2 presented with stage 3a disease, 13 had stage 3c disease, and 3 patients had central nervous system (CNS) involvement (stage 4a and 4c). In addition to planned retrobulbar doses, five patients were given more while two patients received fewer injections (i.e., <5). At the last mean follow-up of 34.67 (±8.88) weeks, 11 patients were in radiological regression and 4 had stable disease while 2 patients had to undergo exenteration; one mortality was observed because of disease progression. Clinical regression in terms of visual and ptosis improvement was seen in seven and nine patients, respectively. Conclusion: Rhino-orbito-cerebral mucormycosis is a serious condition which warrants an aggressive treatment strategy. In unprecedented situations witnessed recently, TRAMB turned out to be an effective and economical alternative. Though large randomized studies are needed to establish its efficacy, TRAMB still manages to halt progression and salvage the globe in significant number of patients, and hence its use should be encouraged on a case-to-case basis especially in developing countries with limited resources.

Corneal manifestations and treatment among patients with COVID-19-associated rhino-orbito-cerebral mucormycosis.

Purpose: TO report the corneal manifestations in patients with COVID-19-associated rhino-orbito-cerebral mucormycosis (ROCM). Methods: This study was a retrospective, observational, and record-based analysis of patients of ROCM with corneal involvement. Results: A total of 220 patients were diagnosed with ROCM over a period of 3 months. Thirty-two patients had developed corneal manifestations. The mean age at diagnosis was 52.84 ± 12.8 years. The associated risk factors were systemic mucormycosis, uncontrolled diabetes, recent COVID-19 infection, and injudicious use of systemic steroids. Twenty-nine patients were known diabetics, 32 had recent COVID-19 infection, and 13 gave a history of injudicious use of steroids. The right eye (RE) was affected in nine patients, the left eye (LE) in 20 patients, and both eyes in three patients. Nine patients had a round-oval corneal ulcer. One patient each had a perforated corneal ulcer with uveal prolapse, sealed perforated corneal ulcer, spontaneously healed limbal perforation, diffuse corneal haze with hyphemia, panophthalmitis, diffuse corneal stromal abscess, limbal ischemia, anterior uveitis with posterior synechiae, inferior corneal facet, and filamentary keratitis. Three patients each had a corneal melt and inferior conjunctival xerosis with chemosis. Orbital exenteration was performed in six patients. Five patients with corneal ulcers healed. Topical eye drops of amphotericin (0.5 mg/ml) cycloplegic, antiglaucoma medications, and lubricant eye drops were started along with systemic antifungals. Conclusion: Central corneal ulcer was the most common manifestation of mucormycosis. A concentration as low as 0.5 mg/ml of amphotericin eye drops was effective in the treatment.

Osteolytic sarcoidosis of the orbit without pulmonary involvement.

A 69-year-old woman with a history of a left orbital mass presented to the emergency room with progressive breakthrough pain in her left orbit despite medical therapy. On examination, there was extraocular motility restriction with diplopia upon left supraduction. Computed tomography (CT) scan of the orbits revealed soft tissue thickening of the left medial and superior periorbita and left lacrimal fossa; bony erosion of the left frontal bone, left orbital roof, and left lamina papyracea; and bilateral mass-like enlargement of the extraocular muscles. An orbitotomy with incisional biopsy was performed, and histopathological examination revealed non-caseating granulomatous inflammation consistent with sarcoidosis. Chest imaging demonstrated no sequela of pulmonary sarcoidosis, and her serum angiotensin converting enzyme (ACE) level was within normal range. She was treated with high-dose oral steroids with resolution of her symptoms. Her pain returned at the conclusion of the steroid taper, and it was controlled with chronic subcutaneous methotrexate and adalimumab injections.

Orbital Subperiosteal Abscess: The Role of Nonsurgical Management Among Adolescents and Adults.

PURPOSE: To investigate the role of nonsurgical management in the treatment of orbital cellulitis complicated by subperiosteal abscess (SPA) in adolescent and adult populations. METHODS: A retrospective cohort study to assess the demographic, clinical, and outcome profiles of adolescent and adult patients with orbital SPA treated nonsurgically versus those who received surgical intervention. Primary outcome measures included hospitalization length and best-corrected visual acuity (BCVA) in the final evaluation. RESULTS: The study comprised 76 patients diagnosed with SPA in the setting of orbital cellulitis. Twelve were stratified into the nonsurgical cohort, while 64 represented the surgical group. Sinusitis was the most prevalent risk factor among both populations, and the rate did not differ significantly. SPA was located medially at a significantly higher rate in the nonsurgical cohort compared with the surgical. No patients in the nonsurgical population had a relative afferent pupillary defect (RAPD) on presentation. The proportion of patients who received adjunctive systemic corticosteroid therapy was comparable in both groups. Hospitalization length was significantly higher in the surgery cohort. BCVA in the final evaluation was favourable in both groups. Sinusitis subgroup analysis including eight nonsurgical patients produced overall consistent results. CONCLUSIONS: Findings from the largest study of orbital cellulitis complicated by SPA to date demonstrate a role for nonsurgical management in adolescent and adult patients who present with a medial SPA and/or ophthalmic examination without an RAPD. Among these populations, visual prognosis is favourable whether management includes surgical debridement or not, and surgical intervention may not predict a shorter duration of hospitalization.

Systemic sarcoidosis presenting as acute rapidly progressive proptosis.

Sarcoidosis is a generalized systemic chronic inflammation that rarely involves the orbit. As a chronic inflammation, sarcoidosis typically manifests with an insidious onset and slowly progressive course. We report a case of acute-onset proptosis resulting from a rapidly growing diffuse orbital mass that simulated malignant growth, which was biopsy proven to be the first manifestation of systemic sarcoidosis. The patient demonstrated complete resolution of proptosis and systemic involvement with long-term corticosteroid treatment.

Erdheim-Chester disease and vemurafenib: a review of ophthalmic presentations and clinical outcomes.

PURPOSE: To provide a comprehensive review of ocular and orbital manifestations of Erdheim-Chester Disease (ECD) and compare clinical outcomes with vemurafenib (INN) to historical treatments (HT). Primary outcomes are ophthalmic findings on presentation, changes in visual acuity, and mortality rate. Secondary outcomes include the progression of ocular findings, systemic involvements, and treatment modalities. METHODS: All published literature from January 1983 to March 2021 was searched for ophthalmic manifestations of ECD. Clinical outcomes following HT were collected and compared with INN. RESULTS: Forty-seven patients with ECD and ophthalmic presentations were identified. The mean age was 49.6 years (SD = 15.0). Proptosis (65.6%) and extraocular muscle restrictions (42.5%) were the most common presenting signs. Of 41 (87.2%) patients with orbital masses on radiologic examination, 90.2% were bilateral, and 53.7% were located in the intraconal space. Ophthalmic examination was significant for xanthelasma (27.2%), optic disc edema (34.0%), and subretinal changes (21.3%). Common treatments were systemic steroids (76.6%), interferon-α (17.0%), and cyclophosphamide (14.9%). INN was less commonly used (12.8%). The mean change in logMAR visual acuity declined with HT (29.9%) but improved with INN (79.1%) (p > 0.05). The proportion of eyes with complete vision loss increased after HT (p < 0.05). The overall mortality rate was 27.7% and notably higher in the HT group (29.3%) when compared to the INN group (16.7%) (p > 0.05). CONCLUSION: ECD presents with many ophthalmic manifestations. Although the intraocular treatments remain controversial, INN should be highly considered in treating orbital ECD patients with BRAF-V600E mutations to prevent and reverse vision loss.

A high-pressure situation.

An 8-year-old boy presented with acute visual loss in the right eye and nausea, vomiting, and diplopia. Imaging revealed a right orbital apex mass. Biopsy showed Langerhans cell histiocytosis (LCH), and the patient was diagnosed with isolated orbital LCH causing an orbital apex syndrome. A 12-month cytarabine chemotherapy course was begun, during which the patient developed bilateral optic disc edema. He was diagnosed with cytarabine-induced intracranial hypertension, which was successfully treated with acetazolamide. The cytarabine course was completed with complete resolution of the LCH lesion. The ophthalmologic relevance of this rare disorder is discussed.

Outcomes of transcutaneous retrobulbar Amphotericin B (TRAMB) as an adjuvant therapy for rhino-orbital-cerebral mucormycosis (ROCM) following COVID-19.

PURPOSE: To assess the outcomes of transcutaneous retrobulbar Amphotericin B (TRAMB) for rhino-orbital-cerebral-mucormycosis (ROCM) post-COVID-19, as an adjuvant to standard systemic antifungal therapy. METHODS: In this prospective cohort study involving ROCM patients with clinical/radiological orbital involvement, 44 eyes with ROCM stage ≥ 3B received TRAMB for 7 consecutive days with liposomal Amphotericin-B (3.5 mg/ml) with a minimum clinical and radiological follow-up of 3 months. All patients received standard systemic antifungal therapy also as per institutional protocol. Data pertaining to demography, systemic status, clinical involvement, imaging, surgical/medical management were also recorded. Potential eyes for exenteration were excluded. Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name). Author 12 Given name: [Mahendra Kumar ] Last name [Garg]. Also, kindly confirm the details in the metadata are correct.All author names are presented accurately. Details in the metadata are correct. Thank you. RESULTS: Forty-four eyes of 42 patients were included, out of which 30 had diabetes mellitus & 22 had received steroid/oxygen treatment during COVID-19 infection. Forty eyes showed improvement or stable disease on follow-up on radiology. Four eyes which showed progression of the disease in orbit were reaugmented with TRAMB. No patient required exenteration. Subconjunctival haemorrhage occurred in six eyes and temporary blurring of vision in four eyes after TRAMB which resolved spontaneously. CONCLUSION: TRAMB, as an adjuvant to standard systemic antifungal therapy, is associated with a significant reduction or stabilisation of orbital involvement. TRAMB should be considered as an adjuvant therapy for ROCM to reduce disease progression as well as to preserve globe or sight. It has a promising role in preventing potential orbital exenterations.
