ABSTRACT

Purpose@#We assessed the clinical manifestations and prognostic factors associated with ocular infection in patients diagnosed with orbital and preseptal cellulitis. @*Methods@#We enrolled 40 patients diagnosed with ocular infection accompanied by orbital and preseptal cellulitis between October 2015 and December 2021. We divided patients into the “treatment success group” (patients whose infection resolved) and the “treatment failure group” (patients whose infection worsened and required evisceration). Clinical characteristics, such as infection-related ocular findings and microbiological features, were analyzed retrospectively in both groups. Chi-square tests and logistic regression analyses were performed to identify prognostic factors associated with treatment failure. @*Results@#The mean age of patients was 72.8 ± 11.92 years, with 17 (42.5%) of them being male. Among the patients, 11 had bacterial infections, and 3 had fungal infections. In total, 6 (15%) and 34 (85%) patients were classified into the treatment success and failure groups, respectively. The chi-square test revealed a significant association between the treatment failure group and several clinical factors, such as low best corrected visual acuity (BCVA), the logarithm of the minimum angle resolution (logMAR) BCVA > 2, low intraocular pressure (IOP) 2, IOP < 5 mmHg, large size of the corneal lesion, and a prolonged duration of symptoms demonstrated significant association with treatment failure. Notably, hypopyon is an important prognostic factor for treatment failure.

ABSTRACT

Purpose@#Liver grafts from donors with HBV infection contributed to expanding the donor pool under the hepatitis B immunoglobulin and antiviral agents (nucleos(t)ide analogues) in the HBV-endemic area. We report long-term outcomes of liver transplantations (LTs) using grafts from donors with active or chronic HBV infection. @*Methods@#Overall, 2,260 LTs performed in 3 major hospitals in Seoul from January 2000 to April 2019 were assessed for inclusion. Twenty-six grafts (1.2%) were obtained from HBsAg (+), HBeAb (+), or HBcAb (+) donors, and recipient outcomes were retrospectively reviewed. Donor and recipient demographics and transplantation outcomes were analyzed. @*Results@#Sixteen deceased donor LTs were performed using active HBsAg (+) grafts. Ten other LTs were sourced from 10 living donors. There was no significant difference in survival in patients who received deceased donor LTs compared with that in those who underwent LT with non–hepatitis virus-infected grafts. Fourteen patients who were followed up for >5 years were stable, and no difference in hepatocellular carcinoma recurrence rate was observed 5 years after transplantation between transplants from donors with and those without HBV. @*Conclusion@#Considering long-term outcomes, liver grafts from donors with active HBV replication can be safely used for LT.

ABSTRACT

To investigate differences of tear neuromediators between subjects with and without dry eye (DE) depending on the ocular sensitivity. Thirty-one subjects with DE and 29 subjects without DE were recruited in this study. The eyes were stimulated by exposure to an irritating product applied to the periocular region. Both DE and non-DE subjects were divided into the high sensitivity and low sensitivity groups based on the degree of ocular sensitivity to ocular irritation. Baseline tear film break-up time (TBUT) and corneal staining score were examined, and tear samples were collected. The concentrations of the tear neuromediators, including nerve growth factor (NGF), serotonin, calcitonin gene-related peptide (CGRP), substance P, neuropeptide Y, and vasoactive intestinal peptide were measured using the enzyme-linked immune sorbent assay. The baseline neuromediator concentrations were compared between subjects with and without DE based on ocular sensitivity. In both DE and non-DE subjects, baseline TBUT was significantly lower in the high sensitivity group than in the low sensitivity group. In the high sensitivity group, baseline tear NGF levels were higher in subjects with DE than in those without DE. In the low sensitivity group, baseline levels of tear CGRP were lower in subjects with DE than in those without DE. Tear neuromediators associated with DE had differences in their concentrations depending on ocular sensitivity. In patients with DE, tear NGF levels increased with high ocular sensitivity to ocular irritation, whereas tear CGRP levels decreased with low ocular sensitivity.

ABSTRACT

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.

ABSTRACT

Purpose@#To evaluate the clinical efficacy of amniotic membrane extract eye drops (AMEEDs) in patients with persistent epithelial defects (PEDs) of the cornea. @*Methods@#Sixteen patients with PEDs refractory to the conventional treatment were further treated with AMEEDs six times a day. Visual acuity, visual analog scale (VAS), esthesiometer score, and areas of the epithelial defects before and after 1 and 2 months of treatment were evaluated. After 2 months, AMEEDs were considered effective if all epithelial defects were healed, partially effective if the epithelial defects decreased in size compared with the baseline, and ineffective if the epithelial defects increased in size and required additional treatment. @*Results@#After 2 months of treatment with AMEEDs, there was a reduction in the area of epithelial defects (5.2 ± 3.1 mm2 vs. 0.1 ± 0.1 mm2, respectively, p = 0.01), as well as a significant improvement in best-corrected visual acuity (0.8 ± 0.5 logarithm of minimal angle of resolution [LogMAR] vs. 0.6 ± 0.3 LogMAR, respectively, p = 0.03), and VAS scores (4.3 ± 1.0 vs. 2.8 ± 0.7, respectively, p = 0.04) compared with the baseline values. Treatment with AMEEDs was effective in 13 (81.3%) patients and partially effective in three (18.8%) patients. @*Conclusions@#AMEEDs could stimulate epithelial wound healing and improve ocular symptoms in patients with refractory PED. Therefore, AMEEDs could be considered an effective treatment option for refractory PEDs.

ABSTRACT

Purpose@#To investigate the efficacy of intense pulsed light (IPL) treatment in patients with meibomian gland dysfunction (MGD) associated with Sjögren’s syndrome. @*Methods@#This study included 43 patients with MGD and Sjögren’s syndrome. Patients received either IPL with meibomian gland expression (IPL/MGX) (n = 22) or MGX only (n = 21). Treatments were administered three times at a 3-week interval. Patients were followed up 6 weeks after the end of the treatment. Ocular Surface Disease Index (OSDI), tear film breakup time with fluorescein dye (FBUT), non-invasive tear breakup time, tear meniscus height (TMH), Schirmer test, SICCA ocular surface staining score, meibum quality score (MQS), and meibum expression score (MES) were evaluated at each visit. Meibomian gland dropouts (meiboscore) and tear film lipid layer grade were measured using keratography. @*Results@#OSDI, FBUT, corneal surface staining score, MQS, meiboscore, and tear film lipid layer grade improved after IPL/MGX treatment (p < 0.05). In both treatment groups, MES significantly improved (p < 0.01 and p < 0.05 for IPL/MGX and MGX groups, respectively). The Schirmer test score, conjunctival surface staining score, and TMH after treatment were not significantly different between the groups. After treatment, the IPL/MGX group had significantly lower OSDI, FBUT, corneal staining score, MQS, and MES, but higher FBUT, compared with the MGX group (p < 0.05). @*Conclusions@#IPL treatment effectively improved tear film, ocular surface parameters, meibomian gland function, and lipid layer grade in patients with Sjögren’s syndrome and MGD.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Purpose@#To analyze the clinical manifestations of culture-proven infective keratitis patients over a recent 10-year period. @*Methods@#We retrospectively reviewed the medical records of 956 cases of infective keratitis between January 2008 and December 2017 at eight tertiary hospitals. The study was performed to analyze the risk factors, causative microbial organisms, therapeutic outcomes, and prognosis. @*Results@#The most common risk factor of keratitis was trauma (33.2%). Initial visual acuity (V/A) was finger count or less in 449 eyes (47.0%). The common location of keratitis was central, and the size was 4 mm2 or less. Hypopyon was observed in 295 eyes (30.9%). Of the 1,039 cultured isolates, 443 (42.6%) grew Gram-negative bacteria with the most common being Pseudomonas aeruginosa. The most prevalent Gram-positive bacteria was Staphylococcus epidermidis, and fungi was Fusarium species. Surgical treatments were performed in 201 eyes (21.0%), followed by amniotic membrane transplantation (66 eyes) and evisceration (44 eyes). Final V/A was 20/100 or more in 422 eyes (44.1%). Gram-positive organisms were highly susceptible to moxifloxacin and vancomycin, and Gram-negative organisms were highly susceptible to levofloxacin and ceftazidime. An increase in resistance to these antibiotics was detected for Enterococcus and Pseudomonas. @*Conclusions@#In South Korea, infective keratitis occurs frequently in eyes with trauma. Staphylococcus epidermidis, Pseudomonas aeruginosa, and Fusarium species are commonly identified etiologies of microbial keratitis. The appropriate administered medical and surgical treatments of suspected infectious keratitis can lead to visual improvement with particular care taken to minimize infection related to resistant bacteria and fungal microbes as needed. An initial V/A of 0.02 or less, the presence of hypopyon, age of 65 years or more, and a central lesion were associated with poor clinical outcome of bacterial keratitis. Age of 70 years or more was a significant risk factor for poor clinical outcome of fungal keratitis.

ABSTRACT

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.

ABSTRACT

Purpose@#To evaluate the correlations between tear osmolarity and matrix metallopeptidase-9 (MMP-9) and dry eye (DE) indices in patients with DE associated with Sjögren’s syndrome (SS). @*Methods@#Sixty-three patients with DE associated with SS who underwent tear analysis were included. DE tests performed were ocular surface disease index, tear break-up time, Schirmer’s test, ocular staining score, and tear osmolarity and MMP-9 tests. Correlations between tear osmolarity and DE indices, differences between patients with abnormal and normal tear osmolarity, and those between positive and negative MMP-9 patients were analyzed. Patients were classified into four groups according to tear osmolarity and MMP-9 results, and between-group differences were analyzed (group 1: abnormal tear osmolarity, MMP-9 positive; group 2: abnormal tear osmolarity, MMP-9 negative; group 3: normal tear osmolarity, MMP-9 positive; group 4: normal tear osmolarity, MMP-9 negative). @*Results@#Mean age of patients was 54.2 ± 13.9 years, and 96.2% were female. Thirty-five patients had abnormal tear osmolarity and 40 patients were MMP-9 positive. DE indices differed between groups with abnormal and normal tear osmolarity (p < 0.01), but not between positive and negative MMP-9 groups. There were 22 patients in group 1, 13 in group 2, 18 in group 3, and 10 in group 4. Compared to group 4, tear break-up time was shorter in groups 1 (p < 0.01) and 2 (p = 0.02). Schirmer’s test values in group 1 were lower than those in group 4 (p = 0.03). Ocular staining score was higher in groups 1 (p < 0.01) and 2 (p < 0.05) than in group 4. @*Conclusions@#Tear osmolarity was correlated with ocular surface indices in DE associated with SS. Combination of tear osmolarity and MMP-9 test results may be helpful to determine the severity of DE associated with SS.

ABSTRACT

Purpose@#To report a case of acute bilateral corneal edema after inhalation of spray paint.Case summary: A 47-year-old male presented with blurred vision in both eyes 12 hours after inhalation of spray paint. He had no history of ocular surgery or chronic ocular disease. The corrected visual acuity was 20/100 in the right eye and 20/40 in the left eye. An ocular examination revealed diffuse bullous changes in the epithelium and mild stromal edema in the cornea of both eyes. At one week after treatment with topical hypertonic solutions and corticosteroids, the visual acuity had improved to 20/20 and slit-lamp examination showed clear corneas without edema. @*Conclusions@#Inhalation of a chemical substance can lead to acute bilateral corneal edema, even without direct contact, but the lesion may resolve rapidly.

ABSTRACT

Purpose@#The number of international visiting scholars has been on the increase in Korea and we aim to investigate the program’s current situation. @*Methods@#This cross-sectional study is based on an online survey questionnaire responded by international visiting scholars in surgical departments of 8 Korean hospitals between 2014 and 2018 about their experiences and satisfaction with the visiting scholar program. @*Results@#A total of 1,496 international scholars from 80 countries visited various surgical departments in 8 Korean hospitals between 2014 and 2018. The numbers have been on the increase over the years. Out of 355 visiting scholars in 2018, 71 replied to the online survey, of whom 52 were male and 19 female, and mostly in their 30s and 40s. Information about the program was accessed mostly through friends or colleagues (42.3%) and international conferences (36.6%). The commonest funding source was private (35.2%) and more than half stayed for less than 3 months. The visiting scholar’s main roles were mostly observation or participation in surgery and clinical research. All but 1 were satisfied with the program (98.6%) and would recommend it to friends and colleagues, although the language barrier was identified as an inconvenience. Those aged 20–39 years with governmental or institutional funding were associated with stays of more than 1 year. @*Conclusion@#The number of international visiting scholars at surgical departments in Korean hospitals has been on the increase with high satisfaction levels. Improvements need to be made on funding sources and lengthening visiting period to maximize the benefits of the program.

ABSTRACT

PURPOSE: We report a case of infectious keratitis caused by Shewanella putrefaciens in a patient after fishing. CASE SUMMARY: A 75-year-old male with no underlying disease other than hypertension was admitted to our hospital because of decreased visual acuity and congestion in his left eye for 2 weeks. At the first ophthalmic examination, the best-corrected visual acuity (BCVA) of the left eye was counting fingers. Slit lamp examination showed stromal infiltrates with 2.0 × 2.0 mm corneal epithelial defects, endothelial inflammatory plaques and 1 mm height hypopyon with severe inflammation in the anterior chamber. Bacterial culture tests were performed by corneal scraping, which were positive for Shewanella putrefaciens, followed by treatment with moxifloxacin and ceftazidime topical antibiotics. After 2 months of treatment, the BCVA of the left eye improved to 0.4 and the corneal lesion clinically improved with residual mild stromal opacity. CONCLUSIONS: Shewanella putrefaciens should be considered as a causal pathogen of infectious keratitis in patients after fishing. We report a case of infectious keratitis caused by Shewanella putrefaciens, which has never previously been reported in the Republic of Korea.

ABSTRACT

PURPOSE: To evaluate the efficacy and safety of cyclosporine nanoemulsion 0.05% compared to cyclosporine emulsion 0.05% and diquafosol sodium 3%. METHODS: This was a multicenter, randomized, evaluator-masked, active control, parallel, phase IV study. A total of 227 patients were randomly allocated to instill cyclosporine nanoemulsion 0.05% (CN) twice daily, cyclosporine emulsion 0.05% (CE) twice daily, or diquafosol sodium 3% (DQ) six times daily. Non-inferiority of CN was analyzed by primary endpoint (cornea and conjunctival staining scores at week 12). The secondary endpoints were scores of corneal staining, conjunctival staining, tear break-up time, Schirmer test, and Ocular Surface Disease Index at weeks 4 and 12. RESULTS: Primary endpoints showed statistically significant improvements in all groups. Primary endpoints were −6.60 for the CN group, −5.28 for the CE group, and −6.63 for the DQ group (National Eye Institute scale from 0 to 33), verifying the non-inferiority of CN compared to CE (95% confidence interval, −0.15 to 2.80, Δ>−2.88). In intergroup comparison between CN and CE groups, the CN group had significantly more decreased conjunctival staining score at week 12. Intergroup comparison between CN and DQ groups showed consistent statistically significant improvements in TBUT and Schirmer test in the CN group. In the DQ group, TBUT showed late statistically significant improvement at week 12 and Schirmer test showed relatively short-term statistically significant improvement at week 4. CONCLUSIONS: Cyclosporine nanoemulsion 0.05% was equivalently efficient compared to cyclosporine emulsion 0.05% and diquafosol sodium 3%.

ABSTRACT

PURPOSE: We report a rare case of solitary neurofibroma on the eyelid margin without neurofibromatosis. CASE SUMMARY: A 46-year-old male presented with a well-define small nodular lesion on the right upper eyelid margin that had not changed for 10 years. Surgical excision and biopsy were performed. Histological examination showed spindle-shaped cells in the fibrous stroma on hematoxylin & eosin staining, and immunohistochemical staining revealed S-100 protein-positive cells. Dermatologic, neurologic, and genetic evaluations showed no evidence of systemic neurofibromatosis. Six months after operation, there was no evidence of local recurrence. CONCLUSIONS: To the best of our knowledge, this is the first case of solitary neurofibroma involving the eyelid margin without neurofibromatosis in Korea. Neurofibroma should be considered in a differential diagnosis of eyelid mass and can be successfully managed with surgical excision.
