Only several case series have been reported. We aimed to describe the clinical manifestations, histopathology and treatment outcomes of MSK.METHODS AND ANALYSISRetrospective data of MSK diagnosed between January 2009 and December 2020 at the King Chulalongkorn Memorial Hospital, Bangkok, Thailand were retrieved. The diagnosis was made based on corneal scraping, corneal biopsy and corneal button histopathology findings. Detailed clinical characteristics, histopathological findings and treatment outcomes were reviewed and analysed.RESULTS21 patients with MSK with a mean age of 63.8 years (SD 12.2) had an indolent disease onset with a median of 9 months (IQR 2.2-12.0). Five patients (23.8%) experienced ocular traumas. Herpes stromal keratitis was the most common preliminary diagnosis (33.3%), followed by non-specific ulcers and fungal keratitis. The most common corneal finding was multifocal grey-white lesions with anterior to mid-stromal infiltration and fluffy borders (66.7%). Pathogens were identified by modified trichrome staining of corneal scrapings in 11 of 14 cases (78.6%). Histopathological examination showed positive Ziehl-Neelsen staining in 17 of 19 cases (89.5%). All patients received surgical treatment, with 18 receiving therapeutic penetrating keratoplasty (TPK), 2 undergoing deep anterior lamellar keratoplasty and 1 undergoing femtosecond laser-assisted anterior lamellar keratoplasty. The overall cure rate was 76.2% after the first surgery and 95.2% after the second surgery.CONCLUSIONMSK can be easily underdiagnosed. Clues to diagnosis included a history of chronic refractory stromal infiltration and typical corneal findings of deep stromal infiltration, without epithelial defects. TPK is the preferred treatment for MSK.","PeriodicalId":9286,"journal":{"name":"BMJ Open Ophthalmology","volume":"4 1","pages":""},"PeriodicalIF":2.4,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142258312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We explored clinical, immunological and genetic properties associated with recurrent OT.Methods and analysis A recurrent OT patient population (n=9) was identified. Clinical history, ophthalmological findings and immunological properties were assessed. B and T cell immunophenotyping including interferon-gamma (IFN-γ) responses were analysed. An analysis of 592 immunodeficiency genes was performed.Results The patients experienced 2–7 OT episodes (average 3.7). The first episode occurred at an average of 23.8 (SD 10.1) years of age. All patients had anterior uveitis, vitritis and various fundus lesions of OT. The patients had lymphocyte maturation abnormalities; the proportion of naive CD4 +CD45RA+CCR7+ T cells was high in 5/9 cases, and the percentage of CD4+CD45RA−CCR7− T effector memory cells was reduced in 7/9 cases. An increased percentage of CD19+CD38lowCD21low activated B cells was observed in 5/9 cases. IFN-γ response was reduced in CD4+ (8.45±4.17 vs 21.27±11.0, p=0.025) and CD8+ (39.0±9.9 vs 18.1±18.1, p=0.017) T cells. Genetic analysis revealed several potentially harmful variants in immunologically active ERCC3, MANBA, IRF4, HAVCR2, CARMIL2, CD247, MPO, C2 and CD40 genes.Conclusion Our recurrent OT cases had deviations in lymphocyte maturation and IFN-γ responses possibly caused by genetic reasons. However, limitations of our study include failure to identify uniform genetic mechanisms. In addition, we cannot rule out the possibility that the immunological abnormalities can be triggered by chronic toxoplasmosis.

Methods All the images were obtained from the hospital for training and 10-fold cross-validation. Two methods were used to improve the classification performance: (1) using images labelled with the additional results of OCT as the reference standard and (2) generating models using retinal features from the entire images, the region of interest (ROI) of the optic disc, and the ROI of the macula, and the combination of all the features. Results Overall, we collected 1338 images with paired OCT scans. In 10-fold validation, ARIA achieved sensitivities of 92.2 %, 92.7% and 85.7%, specificities of 88.8%, 86.7% and 80.2% and accuracies of 90.6%, 89.9% and 83.1% using the retinal features from the entire images, the ROI of the optic disc and the ROI of the macula, respectively. We found the model combining all the features has the best classification performance and obtained a sensitivity of 92.5%, a specificity of 92.1% and an accuracy of 92.4%, which is significantly different from other models (p<0.001). Conclusion We used two methods to improve the classification performance and found the best model to detect glaucoma on colour fundus retinal images. It can become a cost-effective and relatively more accurate glaucoma screening tool than conventional methods.
