RESUMO
Purpose@#We evaluated the clinical manifestations of, and risk factors for, infectious keratitis in patients with ocular graft-versus-host disease (GVHD). @*Methods@#A total of 11 patients who developed infectious keratitis after a diagnosis of ocular GVHD between January 2015 and December 2020, and 36 who did not (the control group), were included in this retrospective study. We recorded sex, age, any underlying disease, any other organ affected by systemic GVHD, systemic immunosuppressant use, follow-up duration, clinical manifestations, the severity of ocular GVHD prior to infection, the size of the epithelial defect, the depth of infiltration, hypopyon status, and the results of microbiological tests. Systemic and ocular indices (including systemic GVHD status) were compared using the chi-squared test. Risk factors for infection were identified. @*Results@#Of the corneal indices, the presence of corneal filaments, the extent of corneal neovascularization, and the number of corneal epithelial defects were significantly higher in the infected group (p = 0.023, p = 0.004, and p = 0.001, respectively). GVHD severity was also significantly higher in that group (p < 0.001). The presence of corneal filaments, corneal neovascularization, and corneal epithelial defects prior to infection correlated significantly with the risk of infection (p = 0.046, p = 0.010, and p = 0.003, respectively). Multivariate analysis identified corneal epithelial defects as a significant risk factor for infection (p = 0.029). @*Conclusions@#In patients with ocular GVHD, corneal epithelial defects, corneal neovascularization, and corneal filaments prior to infection were associated with the development of infection. In particular, corneal epithelial defects before infection was a significant risk factor for infection.
RESUMO
Purpose@#We report a case of infectious keratitis caused by Eikenella corrodens in a patient who lost visual function.Case summary: A 65-year-old male with histories of a corneal ulcer, glaucoma, and bullous keratopathy visited our hospital complaining of redness and pain in his right eye for the past 10 days. Slit-lamp examination revealed stromal infiltration, a 2-mm-high hypopyon, and severe inflammation of the anterior chamber. Vitreous opacity was evident on ocular ultrasonography. Culture of corneal scrapings yielded Eikenella corrodens. After 5 days of antibiotic treatment, ceftazidime was injected intravitreally and histoacryl glue applied to treat the corneal perforation and the endophthalmitis. Two months later, the eye was not inflamed. @*Conclusions@#Eikenella corrodens should be considered a possible pathogen when a patient with an underlying ocular disease presents with infectious keratitis. A corneal ulcer caused by Eikenella corrodens has not previously been reported in the Republic of Korea.
RESUMO
Purpose@#We investigated the clinical characteristics of visual field (VF) defects in Korean advanced glaucoma patients. @*Methods@#The present study included 109 eyes of 109 advanced glaucoma patients whose mean deviation (MD) is under -12 dB. The subjects were classified into primary open angle glaucoma (POAG) and normal tension glaucoma (NTG) group. Average numeric decibel in each VF points were visualized with color topographic image and dot graph image using python 3.5. VF was divided into four quadrants or two half fields, and the differences in the degree of VF defects in each locations were assessed with raw decibel data. Additionally, mean sensitivity of central 12 points were compared between the two groups. @*Results@#Generally the features of VF defects were severely depressed VF sensitivity at the superonasal quadrant and relatively preserved central area and inferotemporal quadrant in both of the glaucoma groups. But we found the extent of deflection for VF defect in the NTG eyes was higher than that of the POAG eyes (p < 0.05). The POAG eyes tended to show more diffuse and evenly distributed VF defect, whereas NTG eyes tended to have more severely depressed VF at the superonasal quadrant and relatively preserved VF at the inferotemporal quadrant. There was no significant difference in the degree of central VF defects between the two groups. @*Conclusions@#The characteristics of VF defect in Korean advanced glaucoma revealed different features based on the glaucoma diagnosis. The POAG eyes tended to show diffuse VF defects, whereas NTG eyes tended to have more severely depressed VF sensitivity at the superonasal quadrant and relatively preserved VF at the inferotemporal quadrant.
