Purtscher’s-like retinopathy as an initial presentation of adult-onset Still’s disease: a case report and review of the literature

Purtscher's and Purtscher-like retinopathy etiology, features, management, and outcomes: A summative systematic review of 168 cases

BACKGROUND

To describe Purtscher's and Purtscher-like retinopathy clinical features, etiologies, management options, and visual outcomes.

METHODS

Our protocol was registered on PROSPERO [registration number: CRD42023406843]. Seven online databases were searched: PubMed, Scopus, Medline, ScienceDirect, CENTRAL, clinicaltrials.gov, and Google Scholar. Original articles were included if they reported at least one subject diagnosed with Purtscher's or Purtscher-like retinopathy. The primary outcome is to describe the clinical features of Purtscher and Purtscher-like retinopathies, including etiologies, results of related investigations, management lines, and visual outcomes. All analyses were conducted with the use of Statistical Package for Social Sciences (SPSS) version 27 (IBM SPSS Corp, SPSS Statistics ver. 26, USA) and Cochrane's RevMan software. The methodological quality of included studies was assessed using the NIH quality assessment tools.

RESULTS

A total of 114 articles were included, describing 168 cases of Purtscher's and Purtscher-like retinopathy. Patients were evenly distributed between males (50.89%) and females (49.11%). Average age of patients was 34.62 years old. Trauma was the leading cause of retinopathy, being reported in 39.88% of our patients, followed by systemic lupus erythematosus (SLE) (13.1%) and acute pancreatitis (11.9%). Bilateral symptoms were reported in 57.7% of patients with centrally blurred vision being the most complained symptom (OS: 34.32% and OD: 18%). 75% of patients elicited bilateral retinal findings. Cotton-wool spots were of highest prevalence (58%). Purtscher flecken was seen in 53% of patients. Macular edema was seen in 13% of patients. Overall, patients had a favorable prognosis (53%).

CONCLUSION

Purtscher's and Purtscher-like retinopathies are rare sight-threatening retinopathies that develop most commonly following trauma or other systemic diseases as SLE and acute pancreatitis. Little data is available regarding these conditions, and available data is of low quality. Patients develop bilateral disease in approximately 50% of cases, and several retinal findings are observed, with no specific tendency. Most observed signs are cotton-wool spots in around 55% of patients and Purtscher flecken in 51% of patients. Patients spontaneously recovered, although data is not conclusive. No clear prognostic value of etiological factors is identified, and further research is required in this regard.

Purtscher-like retinopathy in adult-onset Still's disease, complicated by treatment-related central serous chorioretinopathy

Purpose

We describe a case of Purtscher-like retinopathy associated with adult-onset Still's disease, complicated by the development of central serous chorioretinopathy secondary to high dose corticosteroids.

Observations

A 53 year old female diagnosed with adult-onset Still's disease (AOSD) presented to us with findings consistent with Purtscher-like retinopathy in both eyes, with 20/70 visual acuity in the right eye and 20/20 visual acuity in the left eye. She was initiated on high dose corticosteroids by her rheumatologists for her AOSD. A month later, her vision worsened significantly to counting fingers at 3 feet in the right eye and 20/60 visual acuity in the left. Her examination revealed serous macular detachments involving her fovea consistent with central serous chorioretinopathy secondary to exogenous steroids. After discussion with her rheumatologists, she was tapered off her steroids quickly and bridged to steroid sparing agents, with subsequent resolution of her serous macular detachments and improvement of vision back to baseline.

Conclusion and Importance

The association of Purtscher-like retinopathy and AOSD is important from a multidisciplinary standpoint due to the possibility of life-threatening systemic thrombotic microangiopathy. In addition, patients undergoing treatment for AOSD with exogenous corticosteroids may develop central serous retinopathy with vision loss, and may require quick transitioning to steroid-sparing agents if focal laser is not feasible.

Two cases of severe Purtscher-like retinopathy demonstrating recurrence and progression to neovascularization and vitreous hemorrhage

Purpose

To report the clinical course of two cases with Purtscher-like retinopathy (PLR), associated with peritoneal dialysis (PD), demonstrating disease recurrence and progression to neovascularization and vitreous hemorrhage.

Observations

Case 1 (45-year old woman) experienced acute bilateral vision loss. Medical history included hypertension, end-stage renal failure (ESRF), PD, and obstructive sleep apnea. Visual acuity (VA) was 20/100 OD, 20/80 OS. Fundus findings were pathognomonic for PLR and included white streaks within arterioles. Nine months later, repeat imaging demonstrated disease recurrence and progression, including increased ischemia and new retinal neovascularization. The patient was managed with pan-retinal photocoagulation, sleep apnea treatment, and oral corticosteroids. Four months later, VA remained stable without additional progression.

Case 2 (74-year old woman) experienced acute bilateral vision loss. Medical history included hypertension, ESRF, and PD, complicated by peritonitis. VA was 20/25 OD, 20/32 OS. Fundus findings were pathognomonic for PLR and included white streaks within arterioles. Three months later, further acute vision loss occurred, coinciding with recurrent peritonitis. Repeat imaging revealed disease recurrence and progression, including severely increased retinal ischemia. The PD catether was removed and the patient converted to hemodialysis. Bilateral vitreous hemorrhage later complicated the course.

Conclusions and importance

PLR can occur in association with PD, particularly in acute peritonitis. Contrary to classical descriptions, PLR may take a chronic and progressive course, with increasing ischemia and progression to neovascularization or vitreous hemorrhage. Increased surveillance for complications is recommended and treatment of neovascularization may be required.

[Purtscher-like retinopathy associated with adult onset still disease: Case report and review of the literature]

INTRODUCTION

Putscher-like retinopathy is a retinal disease that is similar to the syndrome initially described in 1910 by Purtscher, but occurring in a non-traumatic context.

CASE REPORT

We describe a case of acute, Putscher-like retinopathy in a 48-year-old woman experiencing adult onset Still's disease. The diagnosis was based on fundus examination and fluorescein angiography. Based on a review of the literature, we discuss the current available data on the pathophysiology of this syndrome and its prognostic significance. The treatment remains controversial.

CONCLUSION

When visual functional signs appear during adult Still's disease, it is necessary to evoke Putscher-like retinopathy, and to ask for an ophthalmological expertise.

PURTSCHER-LIKE RETINOPATHY ASSOCIATED WITH ADULT-ONSET STILL DISEASE

PURPOSE

To describe clinical, laboratory, and funduscopic data of a patient presenting with newly diagnosed adult-onset Still disease and Purtscher-like retinopathy.

METHODS

Observational case report.

PATIENT

A 43-year-old man presented with a 3-week history of daily high-spiking fever, diffuse arthralgia and myalgia, sore throat, and a transient nonpruritic maculopapular rash. Two weeks from the onset of his illness, he developed a gradual decrease in visual acuity in both eyes. Fundoscopic examination showed multiple areas of retinal whitening, discrete superficial retinal hemorrhages, and few characteristic Purtscher flecken in the left eye.

RESULTS

The patient was diagnosed with adult-onset Still disease. We used high-dose corticosteroid therapy with complete resolution of adult-onset Still disease, but it was ineffective for recovery of vision.

CONCLUSION

Clinicians should be aware of Purtscher-like retinopathy as a severe ophthalmic complication of adult-onset Still disease.

A comprehensive review on adult onset Still's disease

Adult-onset Still's disease (AOSD) is a systemic inflammatory disorder of unknown etiology usually affecting young adults; spiking fever, arthritis and evanescent rash are commonly observed during the disease. Other frequently observed clinical features include sore throat, hepatomegaly, splenomegaly, lymphadenopathy and serositis. Furthermore, AOSD patients may experience different life-threating complications. Macrophage activation syndrome (MAS) has been reported up to 15% of AOSD patients and it is considered to be the most severe complication of the disease being characterised by high mortality rate. During AOSD, laboratory tests reflect the systemic inflammatory process showing high levels of erythrocyte sedimentation rate and C-reactive protein. In addition, the ferritin levels are typically higher than those observed in other autoimmune, inflammatory, infectious, or neoplastic diseases. Analysing AOSD disease course, 3 different clinical patterns of AOSD have been identified: i. monocyclic pattern, characterised by a systemic single episode; ii. polycyclic pattern, characterised by multiple, ≤ 1 year lasting, flares, alternating with remissions; iii. chronic pattern, related to a persistently active disease with associated polyarthritis. At present, AOSD therapeutic strategy is aimed at targeting pro-inflammatory signs and symptoms, preventing organ damage and life-threating complications and minimising adverse effects of treatment. However, the treatment of AOSD remains largely empirical, lacking controlled clinical trials. High dosages of corticosteroids are usually the first line therapy when the systemic symptoms predominate. Despite this treatment, a large percentage of patients experiences several flares with an evolution toward the chronic disease course and up to 16% of patients die during the follow up, due to AOSD-related complications. On these bases, in the last years, biological agents have been successfully used in refractory cases. Finally, multiple recent lines of evidence have suggested new insights in AOSD pathogenesis unmasking further therapeutic targets. In fact, small molecules, used in experimental MAS models, might represent new therapeutic options.

Adult-onset Still's disease

First described in 1971, adult-onset Still's disease (AOSD) is a rare multisystemic disorder considered as a complex (multigenic) autoinflammatory syndrome. A genetic background would confer susceptibility to the development of autoinflammatory reactions to environmental triggers. Macrophage and neutrophil activation is a hallmark of AOSD which can lead to a reactive hemophagocytic lymphohistiocytosis. As in the latter disease, the cytotoxic function of natural killer cells is decreased in patients with active AOSD. IL-18 and IL-1β, two proinflammatory cytokines processed through the inflammasome machinery, are key factors in the pathogenesis of AOSD; they cause IL-6 and Th1 cytokine secretion as well as NK cell dysregulation leading to macrophage activation. The clinico-biological picture of AOSD usually includes high spiking fever with joint symptoms, evanescent skin rash, sore throat, striking neutrophilic leukocytosis, hyperferritinemia with collapsed glycosylated ferritin (<20%), and abnormal liver function tests. According to the clinical presentation of the disease at diagnosis, two AOSD phenotypes may be distinguished: i) a highly symptomatic, systemic and feverish one, which would evolve into a systemic (mono- or polycyclic) pattern; ii) a more indolent one with arthritis in the foreground and poor systemic symptomatology, which would evolve into a chronic articular pattern. Steroid- and methotrexate-refractory AOSD cases benefit now from recent insights into autoinflammatory disorders: anakinra seems to be an efficient, well tolerated, steroid-sparing treatment in systemic patterns; tocilizumab seems efficient in AOSD with active arthritis and systemic symptoms while TNFα-blockers could be interesting in chronic polyarticular refractory AOSD.

A case of bilateral trochleitis in adult-onset Still's disease

OBJECTIVES

We describe the first case of adult-onset Still's disease (AOSD) presenting with trochleitis and successfully treated with an interleukin-1 receptor antagonist.

METHODS

This is a descriptive case report of one patient, identified in consultation with the inpatient ophthalmology consult service.

RESULTS

A 23-year-old Caucasian male initially presented with complaints of sore throat, myalgias, rash, and fever. After he failed to respond to antibiotic therapy for presumed streptococcal pharyngitis and developed left eye pain with upgaze, he was admitted to the hospital. Laboratory workup revealed elevated inflammatory markers and liver enzymes. He was eventually diagnosed with AOSD. During his hospitalization he developed binocular vertical diplopia, worsening of left eye pain on upgaze, and exquisite tenderness over the region of the left trochlea, consistent with trochleitis. This diagnosis was supported by magnetic resonance imaging (MRI). Soon after onset of left eye symptoms, the right eye developed identical symptoms. He was started on intravenous corticosteroids, which led to the rapid resolution of his ocular and systemic symptoms. However, after transition to oral corticosteroids, his symptoms recurred. He was started on anakinra, an interleukin-1 (IL-1) receptor antagonist, which led to resolution of his ocular and systemic symptoms.

CONCLUSIONS

Trochleitis is an unusual form of orbital inflammation localized to the superior oblique tendon and trochlea complex. It has been associated with a number of systemic inflammatory conditions including systemic lupus erythematous, rheumatoid arthritis, and juvenile idiopathic arthritis. This is the first case of a patient with AOSD presenting with trochleitis. Treatment with IV corticosteroids and anakinra resulted in rapid resolution of his ocular and systemic symptoms.
