RESUMEN
Purpose@#We investigated choroidal thickness according to the classification of glaucoma and related factors in patients with advanced glaucoma. @*Methods@#The present study included 133 eyes of 133 advanced glaucoma patients with a mean deviation of <-12 dB. Patients were classified into primary open angle glaucoma (POAG) and normal-tension glaucoma (NTG) groups. Factors related to the subfoveal and peripapillary choroidal thickness were analyzed using linear regression analysis. @*Results@#The mean peripapillary choroid thickness was 99.20 ± 46.85 µm in the NTG group, which was significantly thinner than in the POAG group (121.85 ± 45.39 µm, p = 0.006). Additionally, in the sectoral comparison, the NTG group had thinner choroids than the POAG group in all areas (p < 0.05 for all). In the linear regression analysis, glaucoma class (p = 0.007), age (p = 0.005), and intraocular pressure (IOP) (p = 0.024) significantly affected the peripapillary choroid thickness. Moreover, age (p = 0.029) and macular thickness (p = 0.002) were significantly associated with subfoveal choroid thickness. @*Conclusions@#In advanced glaucoma, low baseline IOP, NTG, and old age were significantly associated with a thin peripapillary choroid, suggesting an association between thin peripapillary choroid and the etiology of NTG. Further studies are needed to clarify the significance of a thin choroid in the pathogenesis of glaucoma.
RESUMEN
Purpose@#To evaluate the clinical efficacy of preservative-free 0.15% sodium hyaluronate eye drops on the ocular surface after upper eyelid surgery. @*Methods@#This study included 43 patients who underwent upper eyelid surgery between December 2018 and May 2019. Patients were randomly assigned to group A (those treated with preservative-free 0.15% sodium hyaluronate eye drops) and group B (the control group). Ocular surface disease index score (OSDI), tear break up time (TBUT), Schirmer’s test, corneal staining score (CSS), meibomian gland (MG) quality, MG expressibility, and meiboscore were evaluated before surgery and at 1 week, 1 month, and 2 months after surgery. @*Results@#In group A, OSDI and TBUT showed a significant increase at 1 week after surgery compared with baseline values (all p < 0.05). In group B, OSDI, TBUT, and CSS were significantly higher at 1 week and 1 month after surgery (all p < 0.05), whereas there were no significant changes at 2 months after surgery compared with baseline values. At 1 month after surgery, OSDI (p = 0.03) and CSS (p < 0.01) showed significant changes between group A and group B; however, there was no significant change in the TBUT. There were no significant within-group differences in Schirmer’s test values, MG quality, MG expressibility, or meiboscore, and there were no significant between-group differences over time. @*Conclusions@#Preservative-free 0.15% sodium hyaluronate eye drops were shown to be an effective treatment for early dry-eye symptoms and ocular surface damage after upper eyelid surgery.
RESUMEN
Purpose@#We evaluated the clinical manifestations and risk factors of fungal keratitis after penetrating keratoplasty (PKP). @*Methods@#Eighteen patients who experienced fungal keratitis after PKP between January 2005 and January 2020 were included in this retrospective study. Clinical characteristics including sex, age, underlying disease, indication for PKP, symptom duration, visual acuity, graft state before infection, suture-related problems, size of epithelial defect, depth of infiltration, presence of hypopyon, use of eyedrops before infection, and the results of microbiological tests were analyzed. Patients were classified into the treatment success or failure group, and the risk factors were evaluated accordingly. @*Results@#The mean age at diagnosis was 63.94 ± 15.53 years. Fungal infection occurred a mean of 55.31 ± 44.72 months after PKP. The mean symptom duration was 10.33 ± 7.36 days. Of the 18 patients, 5 (27.8%) and 13 (72.2%) were in the treatment success and failure groups, respectively. Of the treatment failure group, seven patients (38.9%) underwent surgical management. The graft state before infection, symptom duration, and size of epithelial defects had significant correlations with treatment failure (all p < 0.05). Multivariate analysis identified graft state (p = 0.046) as a significant risk factor for treatment failure. @*Conclusions@#Graft state before infection, symptom duration, and size of epithelial defects were associated with the prognosis of fungal keratitis after PKP. Graft state before infection was a significant risk factor for treatment failure.
