[PMID: 38191658 PMCID: PMC11076467 DOI: 10.1038/s41433-023-02916-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Revised: 11/27/2023] [Accepted: 12/20/2023] [Indexed: 01/10/2024] Open
Abstract
Ocular toxoplasmosis is the most common cause of infectious posterior uveitis. Available literature is still conflicting regarding the incidence of recurrence during pregnancy as various calculations were employed in the different published studies. Although earlier reports have suggested a difference in presentation and an increase in severity during pregnancy, newer studies appear to show otherwise. Further diagnostic testing, including serologic and intraocular fluid sampling, may be indicated to increase the diagnostic accuracy in this special population of patients. The management of ocular toxoplasmosis during pregnancy is challenging as the foetus is additionally considered in the choice of treatment. Traditionally preferred anti-toxoplasmosis regimens containing antifolate drugs, such as pyrimethamine and trimethoprim-sulfamethoxazole, cannot be used routinely in pregnant patients, especially during the first trimester. This review includes literature on alternative treatments for ocular toxoplasmosis during pregnancy, including spiramycin and intravitreal treatment options.

Abstract
PURPOSE The purpose of this study is to report one case of ocular toxoplasmosis (OT) recurrence after vitrectomy and review the scientific basis about it. CASE REPORT A 58-year-old male patient with previous OT, properly treated, underwent vitrectomy due to macular hole. During follow-up, patient evolved with recurrence of the OT. After 1 year, patient presents visual acuity of 20/200 and extensive macular scar. CONCLUSION There is no consensus on using perioperative antiparasitic therapy aiming recurrence prophylaxis. Studies with better statistical design are necessary to evaluate the recurrence risk after ocular surgeries and the possible recommendation of prophylaxis, especially in countries where the strains are more virulent and the recurrence more common.

Abstract
Aim: Infectious uveitis is one of the most visually devastating causes of uveitis worldwide and accounts for 19.6% of all cases of uveitis in New Zealand. With the burgeoning use of intravitreal injections, there has been a commensurate increase in the number of injection-related complications and reports of infectious uveitis following their administration in recent years. We present a case series of four patients with infectious uveitis after local injections.Method: We retrospectively reviewed the data of four patients (mean age, 67.25 ± 7.58 years) who presented to the department of ophthalmology at Auckland District Health Board with infectious uveitis which occurred or worsened after local triamcinolone acetonide (TA) and/or methotrexate (MTX) injections.Results: Three patients received local TA and one patient received intravitreal MTX. All patients were immunosuppressed prior to treatment. Two patients had toxoplasma chorioretinitis which worsened with local TA and one patient developed cytomegalovirus (CMV) retinitis after intravitreal TA. The last patient had syphilis retinopathy which worsened with intravitreal MTX. There were atypical presentations, as demonstrated by a case of presumed birdshot chorioretinopathy flare which tested positive for toxoplasma chorioretinitis with polymerase chain reaction (PCR).Conclusion: Uveitis due to infectious etiologies needs to be carefully excluded prior to the use of local steroid and/or methotrexate injections. Disease presentations may be atypical in the presence of marked immunosuppression following local therapy. Polymerase chain reaction (PCR) can play an important role in the diagnosis in this setting.

Abstract
Inflammatory choroidal neovascular membranes are challenging to diagnose and manage. A number of uveitic entities may be complicated by the development of choroidal neovascularization leading to a decrease in central visual acuity. In conditions such as punctate inner choroidopathy, development of choroidal neovascularization is extremely common and must be suspected in all cases. On the other hand, in patients with conditions such as serpiginous choroiditis, and multifocal choroiditis, it may be difficult to differentiate between inflammatory choroiditis lesions and choroidal neovascularization. Multimodal imaging analysis, including the recently introduced technology of optical coherence tomography angiography, greatly aid in the diagnosis and management of inflammatory choroidal neovascularization. Management of these neovascular membranes consists of anti-vascular growth factor agents, with or without concomitant anti-inflammatory and/or corticosteroid therapy.

Abstract
The aim of this study was to report a case of atypical toxoplasma retinochoroiditis following intravitreal triamcinolone acetonide (IVTA) injection and to review the literature pertaining to toxoplasma retinochoroiditis following intravitreal injection of corticosteroid. Clinical data were collected from a 64-year-old male who developed toxoplasma retinitis 2 months after IVTA. A review of the literature was conducted to identify additional reports on similar cases. A 64-year-old male, known diabetic with nonproliferative diabetic retinopathy in both the eyes and optic atrophy in the left eye, presented with atypical retinitis inferior to the disc following IVTA. Real-time polymerase chain reaction and serology confirmed the toxoplasma etiology, and the patient was started on anti-toxoplasma therapy along with oral corticosteroid leading to regression of the lesion by 3 months. A high index of suspicion and proper microbiological diagnosis with appropriate antimicrobial therapy can aid in the management of toxoplasma retinochoroiditis following intravitreal injection of corticosteroid.

Abstract
Purpose To compare clinical outcome of IVCD combined with oral therapy with IVCD alone in patients with toxoplasmic retinochoroiditis. Patients and Methods Thirty eyes were reviewed. Two equal groups were identified (15 eyes each). Clinical outcome measures were resolution of active inflammation, changes in BCVA and CMT, adverse drug reactions, and rate of recurrence. Results Mean baseline of BCVA 1.08 ± 0.17 and 1.03 ± 0.15 improved to 0.64 ± 0.18 and 0.69 ± 0.17 at the end of follow-up in group I and II, respectively. No statistically significant difference was observed. CMT was 392.6 ± 33.16 μm and 397.3 ± 14.6 μm significantly decreased to 314.7 ± 4.43 μm and 319.6 ± 7.8 μm. Resolution of acute inflammation was achieved in all cases in both groups. There were no recurrent cases in group I, and only one out of 15 (6.7%) in group II. No ocular or systemic adverse events were recorded. Conclusion IVCD is an effective route of treatment for active toxoplasmic retinochoroiditis that can be used solely without the need to use systemic medications..

Abstract
We report two cases of fulminant toxoplasmic retinochoroiditis following intravitreal triamcinolone acetonide (IVTA) administration. Case 1: A 42-year-old female received IVTA for presumed non-infectious panuveitis. Within 2 months, she developed diffuse macular retinochoroiditis with optic disc edema. Upon starting anti-toxoplasmic therapy (ATT), her intraocular inflammation resolved with catastrophic damage to the disc and macula. Case 2: A 30-year-old male received IVTA for presumed reactivation of previously scarred toxoplasmic retinochoroiditis. Despite simultaneous ATT, within 6 weeks, he developed extensive, multifocal macular retinochoroiditis. He continued to require ATT for 18 months and later underwent vitrectomy with silicone oil placement for severe epiretinal proliferation. Aqueous tap polymerase chain reactions were found positive for Toxoplasma gondii in both cases. In conclusion, IVTA administration can lead to fulminant toxoplasmic retinochoroiditis even when used with appropriate ATT. Extreme caution should be exercised while administering depot corticosteroids in eyes with panuveitis of unknown origin.

Abstract
Infections by the protozoan parasite Toxoplasma gondii are widely prevalent in humans and animals in Brazil. The burden of clinical toxoplasmosis in humans is considered to be very high. The high prevalence and encouragement of the Brazilian Government provides a unique opportunity for international groups to study the epidemiology and control of toxoplasmosis in Brazil. Many early papers on toxoplasmosis in Brazil were published in Portuguese and often not available to scientists in English-speaking countries. In the present paper we review prevalence, clinical spectrum, molecular epidemiology, and control of T. gondii in humans and animals in Brazil. This knowledge should be useful to biologists, public health workers, veterinarians, and physicians. Brazil has a very high rate of T. gondii infection in humans. Up to 50% of elementary school children and 50-80% of women of child-bearing age have antibodies to T. gondii. The risks for uninfected women to acquire toxoplasmosis during pregnancy and fetal transmission are high because the environment is highly contaminated with oocysts. The burden of toxoplasmosis in congenitally infected children is also very high. From limited data on screening of infants for T. gondii IgM at birth, 5-23 children are born infected per 10 000 live births in Brazil. Based on an estimate of 1 infected child per 1000 births, 2649 children with congenital toxoplasmosis are likely to be born annually in Brazil. Most of these infected children are likely to develop symptoms or signs of clinical toxoplasmosis. Among the congenitally infected children whose clinical data are described in this review, several died soon after birth, 35% had neurological disease including hydrocephalus, microcephaly and mental retardation, 80% had ocular lesions, and in one report 40% of children had hearing loss. The severity of clinical toxoplasmosis in Brazilian children may be associated with the genetic characteristics of T. gondii isolates prevailing in animals and humans in Brazil.

Abstract
Posterior uveitic entities are varied entities that are infective or non-infective in etiology. They can affect the adjacent structures such as the retina, vitreous, optic nerve head and retinal blood vessels. Thorough clinical evaluation gives a clue to the diagnosis while ancillary investigations and laboratory tests assist in confirming the diagnosis. Newer evolving techniques in the investigations and management have increased the diagnostic yield. In case of diagnostic dilemma, intraocular fluid evaluation for polymerase chain testing for the genome and antibody testing against the causative agent provide greater diagnostic ability.
