Pseudo-pigmented choroidal schwannoma with extraocular extension in an elderly patient.

Purpose: To describe a rare case of clinically pigmented choroidal schwannoma with extraocular extension in an elderly patient. Observations: We report a case of a 79-year-old Black male who presented with a clinically pigmented, juxtapapillary choroidal tumor with concern for extraocular extension on standardized ocular echography. The lesion was concerning for choroidal melanoma with extraocular extension. He had no history of cancer or known genetic disease. After an extensive discussion of management options, he underwent enucleation of the left eye. Histopathology of the tumor showed non-pigmented cells with bland, spindle-shaped nuclei and areas of Antoni A pattern along with immunostaining consistent with choroidal schwannoma with extraocular extension. Conclusion: Choroidal schwannoma can mimic choroidal melanoma and can have a clinically pigmented appearance particularly in darkly complected individuals. This case highlights the importance of including choroidal schwannoma on the differential diagnosis for choroidal neoplasms, particularly in populations of individuals in whom melanoma is less common. Though more common in younger patients, choroidal schwannoma can present in elderly patients.

Valsalva-associated orbital compartment syndrome in the setting of frontoethmoidal mucocele and orbital cellulitis.

Valsalva-associated orbital compartment syndrome in the setting of orbital cellulitis, mucocele, or subperiosteal abscess has not been previously reported. A previously healthy girl presented with orbital cellulitis complicated by a subperiosteal abscess and frontoethmoidal mucocele. On the day of her planned orbitotomy and endoscopic sinus surgery, she developed a Valsalva-associated retrobulbar hemorrhage and elevated intraocular pressure after crying during a blood glucose fingerstick. An urgent canthotomy and cantholysis in addition to the planned endoscopic sinus procedure was performed. She did well post-operatively with normal vision at follow-up. Based on these experiences, there should be a consideration to implement heightened vigilance to prevent or minimize Valsalva maneuvers in orbital cellulitis patients with subperiosteal abscesses or mucoceles extending into the orbit. While it remains unclear whether and to what degree these patients may be at an increased risk of developing retrobulbar hemorrhage leading to orbital compartment syndrome, we hope that this novel report aids in providing another consideration with the goal of preventing vision loss.

Recombinant zoster vaccine coverage in the United States: An analysis of claims-based data.

Recombinant zoster vaccine (RZV) is recommended for individuals ≥ 50 years of age for protection against herpes zoster (HZ). This study quantifies RZV coverage and assesses predictors for RZV vaccination using a U.S. claims database. Univariate linear regression provided annual prevalence of RZV vaccination and multivariable logistic regression provided ORs and 95% CIs for associations between predictors and RZV vaccination. A total of 4,124,315 individuals (19,080,914 person-years) were included in this study. Since receiving FDA approval for the prevention of HZ, RZV coverage (of at least one dose) has reached approximately 17% within the eligible U.S. population by January 2021, although significant disparities between demographic groups were noted. Our findings suggest that HZ vaccine coverage may be reduced below goal in the U.S. and highlights the importance of continuing to monitor RZV vaccination. Additionally, as our study found disparities in vaccine coverage, attention towards marginalized and medically underserved populations is needed.

Increased Intraocular Pressure During Hemodialysis: Ocular Dialysis Disequilibrium.

A man in his early 70s presented with a 1-month history of headache, left-sided photophobia, periorbital pain, and redness occurring during hemodialysis. He had a history of ESKD secondary to diabetic nephropathy and of proliferative diabetic retinopathy. We observed elevated intraocular pressure during dialysis. A diagnosis of neovascular glaucoma with a compromised iridocorneal angle was made. Medical management of glaucoma and modifications to the hemodialysis regimen were initiated but were insufficient. The resolution of symptoms required surgical management, including cataract extraction with intraocular lens placement, pars plana vitrectomy, and peripheral retina endolaser, and placement of an Ahmed glaucoma drainage valve. This case illustrates the importance of attention to intraocular pressure and risk factors for glaucoma in patients treated with hemodialysis. Clinicians caring for patients treated by hemodialysis should consider hemodialysis-related elevation in intraocular pressure as a possible etiology for headache, visual changes, or ocular symptoms during dialysis and should pursue ophthalmic evaluation.

Sequential endogenous endophthalmitis, fungal keratitis, bacteremia and vertebral osteomyelitis in a person who injects drugs.

PURPOSE: To describe multiple ocular (and non-ocular) manifestations of disease that can present in a person who injects drugs (PWID). We report a case of a patient consecutively presenting across multiple visits to an ambulatory eye care clinic as the initial point of contact for endogenous endophthalmitis, fungal keratitis, bacteremia, and psoas abscess with vertebral osteomyelitis within a matter of weeks. OBSERVATIONS: A 51-year-old male with past medical history of alcohol use disorder and injection drug use was initially seen in an eye clinic three days after suffering vision loss in the left eye associated with floaters, photophobia, and eye pain. After initial workup and treatment for panuveitis, endogenous endophthalmitis was suspected. A pars plana vitrectomy was performed, and intravitreal medications were given. A pathogen was never isolated from vitreous samples. Two weeks later, the patient presented with complaints of pain, blurry vision, and foreign body sensation in his opposite (right) eye. Examination revealed a corneal ulcer later identified as a Paecliomyces fungal infection. Two weeks after this, he developed fever, chills, and right-sided flank pain radiating to his testicles. Following evaluation by the emergency department and subsequent hospitalization after bacteremia was noted, he was found to have a right-sided psoas abscess with lumbar vertebral osteomyelitis. Fluid was drained, cultured, and grew methicillin-sensitive Staphylococcus aureus (MSSA). At his last visit, his best-corrected visual acuity was 20/20 OS and 20/30 OD despite central corneal scarring. It was only after hospitalization that he affirmed recent injection drug use, despite being queried about it through the course of his infections. CONCLUSIONS AND IMPORTANCE: Injection drug use is an increasingly common concern for all healthcare providers as the opioid crisis in the United States remains widespread. This case highlights multiple potential infectious processes which may impact persons who inject drugs when seen by eye care providers. It also describes difficulties in caring for people who inject drugs who may not provide critical and timely information relating to their injection drug use and/or may delay care even when faced with potentially vision- and/or life-threatening conditions.

Self-Inflicted Hand Amputation without Replantation in a Patient with Body Integrity Identity Disorder: A Case Report.

CASE: We describe a patient who self-amputated his hand using a log splitter, because of a long-standing belief that the limb "did not belong to him." On admission, he refused replantation and was found to be nonpsychotic. He was diagnosed with body integrity identity disorder (BIID) and declared competent to make his own medical decisions. A revision amputation was performed. CONCLUSION: BIID is a challenging diagnosis that physicians treating traumatic injuries should be aware of. Many ethicists support elective amputation as a definitive treatment, because of potential harm reduction and because BIID does not respond to conservative modalities such as pharmacotherapy.
