Bilateral ocular ischemic syndrome as a manifestation of Takayasu arteritis in children

Posterior segment manifestations of Takayasu arteritis: A narrative review

Ocular symptoms can be the presenting manifestation of Takayasu arteritis (TA) or could be indicative of disease reactivation. A review of published literature related to posterior segment manifestations of TA by using the keywords "Takayasu arteritis," "ophthalmic manifestations," "retina," "retinopathy," "ocular," "optic nerve," and "optic neuropathy" was performed. In total, 62 case reports and 12 case series were included. The majority of the articles were from Asia (n = 47, 64%). Females outnumbered males in the ratio of 7:1. The mean age of patients was 33 years (range: 8-78 years, SD: 13.5 years). In 58% (n = 41 out of 71) cases, ocular symptoms were the presenting manifestation of the underlying disease. Hypotensive retinopathy was found in 70% of eyes, and hypertensive retinopathy was found in 27%. The mean presenting visual acuity (VA) was +1.03 logMAR (range: -0.12 to 3, SD: 1.07), and at the final follow-up was +1.02 logMAR (range: -0.12 to 3, SD 1.17). VA improved in 34% (n = 29/86), remained stable in 45% (39/86), and worsened in 21% (18/86). The mean follow-up was 9 months (range: 0.5-204, SD: 16 months).

Mimickers of anterior uveitis, scleritis and misdiagnoses- tips and tricks for the cornea specialist

BACKGROUND

Anterior uveitis, inflammation of the anterior chamber and related structures, is a cohort of diseases that can present to almost any general or sub-specialty Ophthalmology practice. Its features classically involve anterior chamber cell and flare. Below the surface of these two signs exist a panoply of diagnoses. BODY: The purpose of this review is to provide a general framework for diagnoses of anterior uveitis that are often missed as well as non-uveitic pathologies that often mimic anterior uveitis. Diagnostic deviation in either direction can have vision-threatening and rarely life-threatening consequences for patients. Using a comprehensive literature review we have collected a broad spectrum of etiologies of anterior uveitis that are easily missed and non-uveitic pathologies that can masquerade as anterior uveitis.

CONCLUSIONS

We present a focused review on specific misdiagnosed anterior uveitis pathologies and some of the conditions that can masquerade as anterior uveitis and scleritis.

Ocular Manifestations of Takayasu's Arteritis-A Case-Based Systematic Review and Meta-Analysis

Takayasu's arteritis (TA) is a type of vasculitis in which inflammation develops in large vessels, especially in the aorta and its branches. Our study aims to determine the prevalence and type of ocular manifestations in TA. A systematic literature search was conducted in December 2022 using three electronic databases (PubMed, Scopus, and Web of Science). The following data were extracted from each article: the name of the first author; the patient's age, sex, and origin (continent); circumstances connected with the diagnosis of TA; symptoms given by the patients; reported ocular manifestations; and administered treatment. The final analysis was based on data collected from 122 cases. Retinal ischemia, followed by optic neuropathy, cataract, and retinal artery occlusion, were the most prevalent eye conditions associated with the disease. Systemic steroid therapy, vascular procedures, and methotrexate were mainly used to treat pulseless disease. Patients mostly complained of gradual vision acuity loss, sudden vision acuity loss, ocular pain, and amaurosis fugax. The diagnosis of Takayasu's arteritis should be considered in patients presenting symptoms of visual decline/loss, ocular pain, or signs of retinal ischemia, optic neuropathy, or early cataract formation. A proper diagnosis is crucial to ensure the patient receives treatment without significant delay.

Therapeutic Management of Ocular Ischemia in Takayasu's Arteritis: A Case-Based Systematic Review

Background

Takayasu’s arteritis (TA) is a rare, chronic granulomatous large-vessel vasculitis that can lead to ocular ischemia. Ocular outcomes after therapeutic management in TA remain largely unknown. We herein conduct a case-based systematic review to address the current treatment options in this particular cohort.

Methods

PubMed, Medline, and EMBASE databases were searched pertaining to ocular outcomes after systemic treatment in TA. Studies reporting ocular examinations before and after treatment in TA patients with ocular ischemia were included. Clinical characteristics, therapies, ocular outcomes, and complications were recorded.

Results

A 29-year-old woman with newly diagnosed TA showed dramatic regression of Takayasu’s retinopathy (TR) following balloon angioplasty. Optical coherence tomography angiography (OCTA) was used as a novel strategy for subsequent follow-up. A total of 117 eyes of 66 patients with a median age of 27 years were included for systematic review. TR was the most common ocular manifestation. Oral steroids were prescribed in nearly all patients (n = 65), followed by the use of methotrexate and antiplatelet therapy. Of the patients, 65.8% and 34.2% underwent open surgery and endovascular procedure, respectively. The median follow-up period was 12 weeks (interquartile range 8–33.5). Surgical therapy showed better ocular improvement (including visual and imaging responses) in both acute and chronic vision loss, along with fewer complications than medical therapy alone. In the surgical group, the visual prognosis was significantly better in patients with initial visual acuity better than 20/200 (p = 0.03) and those who underwent surgery before stage III TR (p = 0.01). Ocular outcomes were equivalent in the two surgical approaches.

Conclusion

Clinicians should be familiar with ophthalmic manifestations of this potentially treatable complication in TA. Compared with medical therapy alone, surgical intervention might be a better choice for both acute and chronic vision loss. Surgery is best recommended before the onset of irreversible ischemia to the globe. A combined regimen (oral steroids, immunosuppressants, and antiplatelet drugs) might be effective for those with surgical contradictions or reluctance to an invasive procedure. Physicians should be aware of the importance of ocular examinations, including OCTA, during the diagnosis and follow-up in TA.

Takayasu Arteritis Presenting as Bilateral Ocular Ischemic Syndrome

A 26-year-old female came in with progressive blurring of vision. She had developed memory loss and complained of headache, significant weight loss, and exertional left calf pain after prolonged walking. Pertinent physical findings included light perception on visual acuity examination, and the brachial and radial pulses of both arms were not appreciable. Thoracic and abdominal aortic imaging by computed tomography with contrast revealed narrowing along the thoracic aorta and its branches. Carotid Doppler showed bilaterally thickened walls in the common carotid arteries, with near total occlusion of the left carotid artery. These findings were consistent with bilateral ocular ischemic syndrome in Takayasu arteritis. She was given methylprednisolone 500 mg intravenously daily for 3 days with noted improvement in vision. She was discharged and showed improvement on prednisone 35 mg/day and aspirin 80 mg/day. On follow-up two weeks post-discharge, she reported being able to see silhouettes of persons and objects.
