Abstract
PURPOSE To document vascular changes in eyes with post-fever retinitis (PFR) pre and post treatment demonstrated using optical coherence tomography angiography (OCTA). METHODS This is a retrospective observational case series wherein patients with PFR were retrospectively evaluated for changes in the retinal vasculature during the course of disease using OCTA. RESULTS At presentation, OCTA revealed flow void areas in superficial and deep capillary plexus (SCP and DCP) corresponding to the areas of retinitis. Post treatment, OCTA showed a significant decrease in the flow void areas with the appearance of new capillary network in both SCP and DCP. The optical coherence tomography also demonstrated normalization of retinal architecture over time. It is speculated that the good visual outcome in PFR could be attributed to the normalization of retinal architecture and remodelling in retinal vasculature. CONCLUSION OCTA being non-invasive can be used to understand and quantify the extent of vascular remodelling in PFR.

Abstract
INTRODUCTION Ocular toxoplasmosis is the leading cause of posterior uveitis worldwide, affecting individuals acrossdifferent age groups. The key to reducing vision loss includes prompt diagnosis and treatment. However, despite the prevalence of ocular toxoplasmosis, there has been little consensus regarding its pathophysiology,clinical features, diagnosis, and especially management. METHODS The data sources were literature reviews, including Pub Med and Medline databases. Search terms included toxoplasmosis, retinitis, vasculitis, vitritis, uveitis alone or in combination with, serum, aqueous, vitreous eye, ocular and review. RESULTS In this review paper, we have sought to provide an overview of the pathophysiology, epidemiology, and clinical features of the disease, both based on current literature and our own clinical experience. We have also discussed the use of serology, ocular fluid, and ophthalmic investigations that could further facilitate the diagnosis of ocular toxoplasmosis.Different management strategies have been reported worldwide, including newer approaches such as local therapy. CONCLUSION A better understanding of critical aspects of ocular toxoplasmosis will hopefully lead to reduced morbidity, including blindness associated with this condition.

Melo LAD, Paiva MRBD, Fernandes-Cunha GM, Silva-Cunha A, Mol MPG, Fialho SL. Clinical outcomes of intravitreal treatment for ocular toxoplasmosis: systematic review and meta-analysis. Rev Soc Bras Med Trop 2023; 56:e05522022. [PMID: 37222350 DOI: 10.1590/0037-8682-0552-2022] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2022] [Accepted: 03/08/2023] [Indexed: 05/25/2023] Open
Abstract
BACKGROUND Ocular toxoplasmosis is the leading cause of infectious posterior uveitis worldwide, accounting for 30-50% of all cases in immunocompetent patients. Conventional treatment is associated with adverse effects and does not prevent recurrence. Intravitreal drug administration can improve disease outcomes and reduce side effects. Herein, we conducted a systematic review and meta-analysis on the efficacy of intravitreal injections for treating ocular toxoplasmosis. METHODS The systematic search was conducted using PubMed, SciELO, and Google Scholar with the descriptors "ocular toxoplasmosis" AND "intravitreal". We analyzed studies that met the inclusion criteria, i.e., experimental cases in patients treated intravitreally for ocular toxoplasmosis. Considering the systematic review, we focused on the number of intravitreal injections, the therapeutic drug class, and the presence of preexisting conditions. To assess the efficacy of intravitreal injections, a meta-analysis was performed using visual acuity, side effects, disease recurrence, and inflammatory responses as variables. RESULTS Intravitreal injection-induced side effects were rarely observed (0.49% [0.00, 1.51%] ). The use of antiparasitic and anti-inflammatory drugs afforded improved visual acuity (99.81% [98.60, 100.00%]) and marked effectiveness in treating ocular toxoplasmosis. CONCLUSIONS Intravitreal injections may facilitate the successful treatment of ocular toxoplasmosis. However, clinicians should carefully evaluate the presence of preexisting conditions for ocular toxoplasmosis or previous diseases, as these can impact the decision to administer intravitreal injections.

Abstract
Ocular toxoplasmosis is the most common cause of posterior uveitis that is caused by Toxoplasma gondii infection. Humans can be infected congenitally or postnatally. The typical lesion of ocular toxoplasmosis is focal necrotizing retinitis with overlying vitritis, which lead to hyperpigmented retinochoroidal scar at resolution of lesion. Macula involvement can cause substantial visual impairment. The high incidence of disease reactivation may lead to greater risk of vision loss. Optical coherence tomography angiography (OCTA) is a non-invasive imaging method to visualize the vascular and density perfusion of the retina and choroid, which cannot be obtained by conventional Optical Coherence Tomography (OCT). In this case report, we present two cases of active ocular toxoplasmosis with multiple recurrences to study pathological changes in retinal and choroidal microvasculature. The findings reveal the involvement of all of the retinal layers in the choroid, with distinct changes in the deep retinal layer.

Abstract
Evaluation of pediatric hypereosinophilia (HE) is challenging, especially in the tropical developing countries, as appropriate diagnostic facilities may be lacking, parasitic/helminthic infections are common, and existing data on the etiology of severe eosinophilia are sparse. Second, data on long-term follow-up of these children including the temporal course of eosinophilia are also scarce. Besides, questions regarding the coexistence of multiple etiologies and their association with the severity of HE are largely unexplored. These challenges and questions often lead to diagnostic and therapeutic dilemmas. We highlight these difficulties utilizing a real-life clinical description. We emphasize the need for long-term follow-up of such children as HE may be the combinatorial effect of multiple etiologies, rather than a single cause. We also describe an unusual association of severe eosinophilia in a child with toxoplasmosis that was treated successfully with 8-week combination therapy with azithromycin and cotrimoxazole (sulfadiazine and pyrimethamine were not available).
