Abstract
PURPOSE To describe demographic data, clinical features, and serological profiles in a cohort of Congolese patients with ocular toxoplasmosis (OT). METHOD Cross-sectional study, carried out between March 2020 and July 2021 in two ophthalmic clinics in Kinshasa. RESULTS The study comprised 95 participants with OT. Fifty-three patients were male (55.8%). The mean age at presentation was 35.6 ± 14.1 years (range 8-69 years); 71 had active OT (74.7%), among them, 33 had primary OT (46.5%), and 38 had recurrences (53.5%). At presentation, 51 patients (53.7%) had visual impairment (VA < 6/18). Retinochoroidal lesions were located in the central retina in 60 patients (63.1%). Patients with primary OT tend to have higher IgG levels than those with recurrent OT (P = .01). CONCLUSION We report the largest cohort of patients with OT in sub-Saharan Africa. In our setting, most patients had recurrent OT with multiple, extensive, and central retinochoroidal lesions.

Abstract
Seroprevalence studies on human toxocariasis help to assess the burden and the morbidity associated with this zoonosis. This review searched the seroprevalence studies and case reports in six North African countries: Algeria, Egypt, Libya, Morocco, Sudan and Tunisia, since 1990. The search also included studies on the environmental factors related to the risk of transmission. Most of the published epidemiological studies were done in Egypt. Cross-sectional and case-control studies in Egypt demonstrated that toxocariasis is a significant zoonosis that could be associated with conditions like bronchial asthma allergies and certain neuropsychiatric disorders. The population at risk of this infection includes all ages, both genders, in contact with dogs, resident in rural areas with poor housing conditions. The publications from Tunisia, Morocco and Algeria are limited to case reports and retrospective analyses of cases, but the disease is probably under-diagnosed in these three countries. There are no published reports on human toxocariasis in Libya and Sudan during the period covered by the review. Animal studies confirm high infection rates of dogs with Toxocara canis in North Africa. There is also evidence of wide-spread contamination of soil and water with Toxocara spp. eggs. Moreover, the use of untreated wastewater for irrigation in parts of North Africa could be a source of contamination of agricultural products with eggs of Toxocara spp. Population-based studies on human toxocariasis are recommended, using standardized diagnostic tests. These surveys should also assess risk factors to guide preventive measures.

Abstract
PURPOSE To determine the epidemiology and clinical pattern of Congolese patients with ocular toxoplasmosis. PATIENTS AND METHODS A retrospective study was conducted on records of patients with ocular toxoplasmosis examined in the Teaching Hospital of Kinshasa (DR Congo) from 2010 to 2012. Each patient underwent a complete ophthalmic examination. Sociodemographic data, clinical symptoms and signs, visual outcome, modality of treatment and type of complications were studied. RESULTS Thirty-five cases of ocular toxoplasmosis were diagnosed out of 18,144 patients, giving a frequency of 0.2 %. Eighteen men (51.4 %) were affected, with a sex ratio of 1.05. The mean age of the patients was 40.9±20 years (range: 10-72 years). The mean time until consultation was 10 months (range: 2 days-84 months). Ocular involvement was unilateral for 65.7 % of patients. Decreased visual acuity (77.1 %) and pain (7.1 %) were the main ocular complains. Chorioretinal lesions involved the central retina in 26 patients (74.3 %). Five patients (14.2 %) developed recurrences during follow-up. Complications affected 17 patients (48.6 %), with macular scarring (34.3 %) and cataract (17.1 %) being the most common. At the first consultation, 61.7 % of the affected eyes had visual impairment (VA<0.3). Visual impairment was associated with macular lesions (P<0.001, OR=3 [1.4-6.1]) and age greater than 45 years (P=0.002, OR=11 [2.2-53.6]). CONCLUSION In our context, complications are common with ocular toxoplasmosis,s and they lead to visual impairment in the majority of patients.

Abstract
PURPOSE To analyze the patterns and etiologies of uveitis at a tertiary referral center in Taiwan. METHODS This retrospective chart review of uveitis patients from January 2001 to December 2014 updates a previous study a decade ago (2003). RESULTS We identified 450 patients, among whom anterior uveitis was most common, followed by panuveitis, posterior uveitis, and intermediate uveitis. A specific diagnosis was identified in 331 patients. In 73 infectious uveitis cases, herpetic anterior uveitis was the leading cause, followed by endogenous bacterial endophthalmitis and acute retinal necrosis. In 258 non-infectious uveitis cases, HLA-B27-associated uveitis was most commonly seen, followed by Vogt-Koyanagi-Harada disease and Posner-Schlossman syndrome. Compared with our previous study, we found more viral infection and sarcoidosis but fewer cases of Behçet disease, tuberculosis, and toxoplasmosis. CONCLUSIONS Our results provide useful information about the patterns and etiologies of uveitis in a selected population in Taiwan.
