Purtscher-like retinopathy and paracentral acute middle maculopathy following breast filler injection

BACKGROUND

To report a rare case of pulmonary and ocular complications with visual loss due to bilateral Purtscher-like retinopathy and paracentral acute middle maculopathy (PAMM) following a hyaluronic acid (HA) filler injection to the breast. Systemic and visual recovery was attained following corticosteroid therapy.

CASE PRESENTATION

A 27-year-old lady presented with painless blurring of vision in both eyes for 2 weeks following hyaluronic acid breast filler injections by a non-medical practitioner. She was initially admitted to the medical ward for diffuse alveolar haemorrhage and altered sensorium. The presenting visual acuity was counting fingers in both eyes. Bilateral dilated fundus examination showed hyperaemic discs, concentric rim of retinal whitening around macula with patches of polygonal-shaped retinal whitening, generalised cotton-wool spots, tortuous veins, and flame-shaped haemorrhages. Spectral-domain optical coherence tomography (SD-OCT) macula revealed hyper-reflective bands at the inner nuclear layer (INL). Fluorescein angiography demonstrated hot discs, delayed arm-to-retina time, arterial filling, and arterio-venous transit time with staining of the vessels at the posterior pole. She was managed with a tapering dose of systemic corticosteroids. The visual acuity improved to 6/12 over 8 weeks with significant anatomical and functional improvement. Dilated fundus examination showed resolution of initial funduscopy findings. The hyper-reflective bands on the OCT had resolved with subsequent thinning of the INL and disorganisation of retinal inner layers.

CONCLUSION

Filler injections are in increasing demand and are frequently being performed by non-medical practitioners. Visual loss from non-facial HA fillers is rare. Inadvertent entry of HA into a blood vessel may potentially cause systemic and sight-threatening ocular complications. Good anatomical knowledge and proper injection technique are vital in preventing this unfortunate sequela. There are limited reports on successful visual recovery following various treatment approaches and we hope this case provides valuable insights.

Guidelines from an expert panel for the management of diabetic macular edema in the Malaysian population

AIM

To derive a Malaysia guideline and consensus as part of the Malaysia Retina Group's efforts for diagnosis, treatment, and best practices of diabetic macular edema (DME). The experts' panel suggests that the treatment algorithm to be divided into groups according to involvement the central macula. The purpose of DME therapy is to improve edema and achieve the best visual results with the least amount of treatment load.

METHODS

On two different occasions, a panel of 14 retinal specialists from Malaysia, together with an external expert, responded to a questionnaire on management of DME. A consensus was sought by voting after compiling, analyzing and discussion on first-phase replies on the round table discussion. A recommendation was deemed to have attained consensus when 12 out of the 14 panellists (85%) agreed with it.

RESULTS

The terms target response, adequate response, nonresponse, and inadequate response were developed when the DME patients' treatment responses were first characterized. The panelists reached agreement on a number of DME treatment-related issues, including the need to classify patients prior to treatment, first-line treatment options, the right time to switch between treatment modalities, and side effects associated with steroids. From this agreement, recommendations were derived and a treatment algorithm was created.

CONCLUSION

A detail and comprehensive treatment algorithm by Malaysia Retina Group for the Malaysian population provides guidance for treatment allocation of patients with DME.

Fenofibrate for the prevention of progression of non-proliferative diabetic retinopathy: review, consensus recommendations and guidance for clinical practice

The prevalence of diabetic retinopathy (DR), and associated morbidity is high in the Asia-Pacific region. Emerging evidence suggests a potential role for fenofibrate in the prevention of progression of DR, especially in patients with cardiovascular risk, and pre-existing mild-to-moderate DR. Fenofibrate has also been found to reduce maculopathy, and the need for laser treatment in these patients. Considering these benefits of fenofibrate, a group of experts from the fields of endocrinology and ophthalmology convened in May 2017, to discuss on the the mechanism of action, and clinical efficacy of fenofibrate in DR. The findings from key clinical studies on fenofibrate in DR were reviewed by the experts, and consensus statements were derived to define the role of fenofibrate in the prevention and treatment of DR. The statements were rated based on the GRADE criteria. An algorithm was also developed for the screening and treatment of DR in patients with type 2 diabetes (T2D), and the place of fenofibrate was defined in the algorithm. The expert recommendations, and the algorithm provided in this review will serve as a guide to the clinicians to reconsider the adjunctive use of fenofibrate for preventing the progression of DR in selected T2D patients.

Demography and clinical pattern of newly diagnosed uveitis patients in Malaysia

Introduction

Uveitis is one of the common causes of visual impairment in Malaysia. It remains a challenging entity to diagnose and manage due to variation in its clinical presentation. This study aims to observe the demographic and clinical pattern of cases from the participating ophthalmology units in Malaysia.

Methods

This study involved prospective and multicentered data collection for patients newly diagnosed with uveitis from 1^st January 2018 to 31^st December 2018. Variables collected and analyzed included age, gender, ethnicity, nationality, state of origin, laterality, granulomatous or non-granulomatous uveitis, and etiology of uveitis.

Results

A total of 1199 newly diagnosed uveitis patients were analyzed within the study period. There was a significant association between the anatomical location of uveitis with age at presentation. The percentage of patients with anterior uveitis was higher in the ‘40 to 60’ years and ‘above 60’ years age groups at 52.1% (n = 210) and 61.3% (n = 114) respectively. In contrast the percentage of patients with posterior and panuveitis was higher in the 1 to 20 and 20 to 40 years age groups at 51.4% (n = 54) and 48.7% (n = 246) respectively.

Sixty three percent of the patients presented with unilateral uveitis (n = 760, p < 0.001) vs bilateral. Non-granulomatous uveitis comprised 84.5% of all patients (n = 1013, p < 0.001) compared to granulomatous uveitis. Non-infectious etiology contributed to 65.7% of all patients (n = 788, p < 0.001) with the majority being unclassifiable uveitis (n = 686, 57.2%,). Specific inflammatory entities contributed to only 8.5% (n = 102) of the non-infectious causes with Vogt-Koyanagi-Harada (VKH) syndrome being the most common (n = 25, 2.1%,). Infectious uveitis comprised 34.3% (n = 411) with tubercular (TB) uveitis (n = 105, 8.8%) and viral uveitis (n = 107, 8.9%) contributing the most followed by ocular Toxoplasmosis (n = 93,7.8%).]

Conclusion

This study has highlighted the demographic data and common causes of uveitis in Malaysia.

Isolated Infiltrative Optic Neuropathy in an Acute Lymphoblastic Leukemia Relapse

Optic nerve infiltration as the first sign of isolated central nervous system relapse of acute lymphoblastic leukemia (ALL) is rare. A seven-year-old girl with standard-risk B-cell ALL who was in remission presented with sudden onset of left eye pain and loss of vision. Examination revealed no perception to light in the left eye with positive relative afferent pupillary defect. The optic disc was hyperemic and swollen with total obscuration of the disc margin associated with central retinal artery and vein occlusion. Magnetic resonance imaging of the brain and optic nerve showed left intraorbital optic nerve thickening associated with perineural enhancement and intraconal fat involvement.

Lumbar puncture revealed leukemic infiltration with blast cells after a week of eye symptoms, while bone marrow aspiration was negative for malignant cells. A diagnosis of left leukemic optic nerve infiltration with central retinal artery and vein occlusion was made. A high index of suspicion with repeat cerebrospinal fluid sampling is crucial to confirm the diagnosis as vitreous biopsy may fail to reveal infiltrative cells.

Cytomegalovirus Retinitis in Primary Immune Deficiency Disease

INTRODUCTION

To report an unusual case of CMV retinitis in Primary Immune Deficiency Disease (PIDD).

CASE REPORT

13-year-old child with combined T and B cell deficiencies was diagnosed of bilateral zone 1 CMV retinitis. Intravitreal injections were unable to be given in a regular and timely manner under general anaesthesia due to her underlying systemic disease. The child was treated with intravenous ganciclovir for 8 weeks until eventual resolution of the retinitis. However, visual acuity deteriorated due to progressive optic nerve involvement.

CONCLUSION

Paediatric patients often do not notice subtle symptoms of CMV retinitis. Although ocular manifestations are uncommon in PIDD, recognition and high index of suspicion will allow for timely referral, diagnosis, and treatment to be instituted for better visual outcomes.

Prevalence of camel brucellosis in Libya

Sera of 967 camels of both sexes were tested for antibodies to Brucella using the Rose Bengal plate test, serum agglutination test and the complement fixation test. The prevalence of positive sera was 4.1 per cent. Samples collected for cultural examination revealed 9 isolates. Five isolates were from milk samples, 3 from aborted foetuses and one from a vaginal swab. All isolates were identified and biotyped as Brucella melitensis biovar 1.
