BACKGROUND
Sporotrichosis is an implantation mycosis caused by species prevalent worldwide, which occasionally can also result in intraocular infection presenting as an exogenous or endogenous infection (disseminated sporotrichosis). Knowledge in its clinical recognition and management is limited.
AIMS
To systematically review and analyse data from published literature with a view to comparing clinical outcomes between exogenous and endogenous endophthalmitis caused by .
METHODS
Case reports of intraocular sporotrichosis, published from 1960 to 2016, were retrieved from MEDLINE, Embase, Cochrane, LILACS and SciELO databases. The entire data set was divided into two patient groups: (1) exogenous endophthalmitis and (2) endogenous endophthalmitis. Primary outcomes were differences in ocular findings and clinical ocular outcomes between the two groups.
RESULTS
From 16 publications retrieved, a total of 8 eyes of 8 patients with exogenous endophthalmitis and 13 eyes of 10 patients with endogenous endophthalmitis were identified. Compared with exogenous endophthalmitis, endogenous endophthalmitis was more common in patients infected with HIV (p=0.001) and those from hyperendemic areas (p=0.036). Anterior uveitis (p=0.015) and posterior uveitis (p=0.04) were more common in the exogenous and endogenous endophthalmitis groups, respectively. The majority of patients with endogenous endophthalmitis had partial or full clinical resolution of ocular lesions with systemic amphotericin B alone or in combination with an oral antifungal, whereas patients with exogenous endophthalmitis had poor outcomes with irreversible vision loss, enucleation and evisceration.
CONCLUSIONS
Anterior uveitis is more common in exogenous endophthalmitis with worse overall outcomes and complications, compared with endogenous endophthalmitis where posterior uveitis is the most common clinical manifestation, especially in patients infected with HIV and those from hyperendemic areas. infection should be included in the differential diagnosis for ocular inflammation, regardless of the presence or absence of autoimmune comorbidities and whether the patient resides in an endemic area or not. Ophthalmologists should consider intravitreal and systemic antifungal therapy for exogenous and endogenous endophthalmitis caused by .

International Ophthalmology Apr 2024To review all studies reporting the onset of white dot syndromes following COVID-19 vaccines. (Review)
Review
PURPOSE
To review all studies reporting the onset of white dot syndromes following COVID-19 vaccines.
METHODS
Our protocol was registered prospectively on PROSPERO [registration number: CRD42023426012]. We searched five different databases including PubMed, Scopus, Web of Science, Google Scholar, and Science Direct up to May 2023. All the studies that reported the occurrence of white dot syndrome following COVID-19 vaccines were included. All statistical tests were conducted with a 95% confidence interval and a 5% error margin. A p value of less than 0.05 was considered statistically significant. The methodological quality of included studies was performed using the IHE Quality Appraisal Checklist for Case Series studies and JBI Critical Appraisal Checklist for Case Reports.
RESULTS
Fifty studies involving seventy-one subjects were included. Multiple evanescent white dot syndrome (MEWDS) was the most common disease (n = 25, 35.2% %), followed by acute macular neuroretinopathy (AMN) (n = 22, 31.0%) and acute posterior multifocal placoid pigment epitheliopathy (APMPPE) (n = 4, 5.6%). They were mostly unilateral (n = 50, 70.4%). The presenting symptoms were blurred vision (n = 26, 36.6%), paracentral scotoma (n = 19, 26.8%), visual field disturbance, and photopsia (n = 7, 9.9%). The mean duration for follow-up was 10.15 ± 14.04 weeks. Nineteen subjects (29.69%) received steroids with improvement reported in 68.4%. Eleven subjects (17.19%) were managed by observation only with reported full recovery and improvement.
CONCLUSION
White dot syndromes are very rare entities. Our findings highlight a possible association between COVID-19 vaccines and the occurrence of white dot syndromes. However, larger studies with good quality should be implemented to confirm these findings.

: To identify prognosis factors and functional outcomes of persistent placoid maculopathy (PPM). : We collected personal PPM cases and combined them with the data from the literature. : 68 eyes of 37 patients with PPM were analyzed, including six new cases. Twenty-six patients were men (70%) with a mean age of 51.8 years old. The mean initial visual acuity (VA) was 0.52 LogMar ± 0.55 for a mean final VA of 0.49 LogMar ± 0.51. Risk factors for poor VA included: initial VA less than 0.2 LogMar ( < .0001), cardiovascular risk factor ( = .008), autoimmune-related and/or systemic pro-inflammatory conditions ( = .003), choroidal neovascularization ( = .001), macular atrophy ( = .03) and absence of systemic corticosteroid treatment ( = .03). : PPM is a choroidal inflammation. Identifying prognosis factors may help to guide treatment and follow-up. We showed that anti-inflammatory drugs, and anti-VEGF injections in cases of choroidal neovascularization, may lead to better outcomes.

Considering the widespread use of COVID-19 vaccines as a preventive measure against the spread of the virus, it's necessary to direct attention to the adverse effects associated with vaccines in a limited group of populations. Multiple evanescent white dot syndrome (MEWDS) following COVID-19 vaccination is a rare adverse reaction associated with COVID-19 vaccines. In this systematic review, we collected 19 articles with 27 patients up to November 1, 2023, summarizing the basic information, clinical manifestations, examinations, treatments, and recoveries of the 27 patients. The 27 enrolled patients (6 males, 21 females) had a median age of 34.1 years (15-71 years old) and were mainly from 5 regions: Asia (8), the Mediterranean region (8), North America (7), Oceania (3) and Brazil (1). Symptoms occurred post-first dose in 9 patients, post-second dose in 14 (1 with symptoms after both), post-third dose in 1, and both post-second and booster doses in 1, while details on 2 cases were not disclosed. Treatments included tapered oral steroids (6), topical steroids (3), tapered prednisone with antiviral drugs and vitamins (1), and valacyclovir and acetazolamide (1), while 16 received no treatment. All patients experienced symptom improvement, and nearly all patients ultimately recovered. Moreover, we summarized possible hypotheses concerning the mechanism of COVID-19 vaccine-associated MEWDS. The findings provide insights into the clinical aspects of COVID-19 vaccine-associated MEWDS. More attention should be given to patients with vaccine-associated MEWDS, and necessary treatment should be provided to patients experiencing a substantial decline in visual acuity to improve their quality of life.
