Visual Outcomes According to Age After Bilateral Implantation of Trifocal Intraocular Lenses.

PURPOSE: To investigate the effect of age on visual outcomes after the bilateral implantation of trifocal intraocular lenses (IOLs). METHODS: A total of 290 patients (580 eyes) who underwent bilateral implantation of a trifocal IOL were enrolled in this retrospective case-control study. Patients were divided into five age groups: 45 to 49, 50 to 54, 55 to 59, 60 to 64, and 65 years and older. Postoperative monocular uncorrected and corrected distance visual acuity (UDVA and CDVA, respectively), uncorrected near visual acuity (UNVA), binocular distance-corrected defocus curve, spectacle dependence for near and distance vision, and patient satisfaction scores were compared among the five groups. RESULTS: The 45 to 49 years group had significantly better mean UDVA (0.02 ± 0.05 logMAR) and UNVA (0.02 ± 0.04 logMAR) than the 65 years and older group (0.06 ± 0.09 and 0.09 ± 0.09 logMAR; P = .029 and P < .001; respectively). However, no significant differences were observed in the mean CDVA among the groups. Binocular visual performance of the 45 to 49 years group was better than that of the 65 years and older age group at defocuses of +1.00, +0.50, -1.00, and -3.00 D. No significant differences were observed in spectacle dependence for near and distance vision or in patient satisfaction scores among the five groups. CONCLUSIONS: Bilateral implantation of trifocal IOLs can provide excellent near and distance vision in both young and older patients. However, UDVA and UNVA revealed considerably worse results in the older group, although no significant difference was observed in CDVA and postoperative refractive errors by age.

Deep learning-based fully automated grading system for dry eye disease severity.

There is an increasing need for an objective grading system to evaluate the severity of dry eye disease (DED). In this study, a fully automated deep learning-based system for the assessment of DED severity was developed. Corneal fluorescein staining (CFS) images of DED patients from one hospital for system development (n = 1400) and from another hospital for external validation (n = 94) were collected. Three experts graded the CFS images using NEI scale, and the median value was used as ground truth. The system was developed in three steps: (1) corneal segmentation, (2) CFS candidate region classification, and (3) estimation of NEI grades by CFS density map generation. Also, two images taken on different days in 50 eyes (100 images) were compared to evaluate the probability of improvement or deterioration. The Dice coefficient of the segmentation model was 0.962. The correlation between the system and the ground truth data was 0.868 (p<0.001) and 0.863 (p<0.001) for the internal and external validation datasets, respectively. The agreement rate for improvement or deterioration was 88% (44/50). The fully automated deep learning-based grading system for DED severity can evaluate the CFS score with high accuracy and thus may have potential for clinical application.

Comparison of posterior capsule rupture rates during phacoemulsification using 3D heads-up visualization system and traditional microscopes.

PURPOSE: To compare the posterior capsule rupture (PCR) rates of cataract surgery using a traditional ophthalmic surgical microscope (OSM) and a 3D heads-up visualization system (HUVS). SETTING: Single tertiary referral center. DESIGN: Retrospective study. METHODS: This study included 10 101 eyes that underwent phacoemulsification cataract surgery. Surgeries were performed using either 3D HUVS (1964 eyes, performed by 2 surgeons, HUVS group) or traditional OSM (8137 eyes, performed by 6 surgeons, OSM group) from February 2018 to June 2022. Data were collected based on the diagnosis-related group system, and the rate of PCR requiring vitrectomy and the surgical time were evaluated. RESULTS: The PCR rates were not significantly different between the OSM (n = 63; 0.7%) and HUVS (n = 19; 0.9%, P = .392) groups. The mean surgical time was significantly longer in the HUVS group (14.7 ± 10.6 minutes) than in the OSM group (12.9 ± 9.9 minutes, P < .001). In the 3D HUVS group, there were no PCR cases among the initial 100 patients. In both groups, no significant difference was observed in the PCR rates over time. Although the difference was not statistically significant, the PCR rate decreased over time in the HUVS group. CONCLUSIONS: The results indicate that 3D HUVS-based cataract surgery performed by experienced cataract surgeons had a PCR rate similar to that of traditional OSM-based surgery during the 4-year study period. Although the surgical time was slightly longer with 3D HUVS, cataract surgery using 3D HUVS can be performed safely by experienced surgeons.

Accuracy of the PEARL-DGS Formula for Intraocular Lens Power Calculation in Post-Myopic Laser Refractive Corneal Surgery Eyes.

PURPOSE: To investigate the accuracy of the PEARL-DGS formula for intraocular lens (IOL) power calculation in post-myopic laser refractive corneal surgery eyes. DESIGN: Retrospective case series. METHODS: A total of 139 eyes of 139 patients (mean axial length: 27.4 ± 2.1 mm) who had prior myopic laser refractive corneal surgery and subsequent cataract surgery using Tecnis ZCB00 from March 2018 to February 2023 were included. Refractive outcomes of 5 formulas (Barrett True K, Haigis-L, Hoffer-QST, PEARL-DGS, and Shammas-PL) were evaluated. Prediction error was defined as the difference between the measured and predicted postoperative refractive spherical equivalent using the IOL power actually implanted. Mean prediction error (MPE), median absolute prediction error (MedAE), and mean absolute prediction error were calculated. RESULTS: Without constant optimization, the PEARL-DGS resulted in a MPE of +0.05 ± 0.65 diopters (D), whereas the other formulas resulted in myopic shifts. The MedAEs of the formulas were 0.39, 0.53, 0.65, 0.85, and 1.11 D for the PEARL-DGS, Hoffer-QST, Barrett True K, Shammas-PL, and Haigis-L, respectively, in order of magnitude (P < .05). With constant optimization, there were no statistically significant differences in the MedAEs among the 5 formulas (P = .388). CONCLUSIONS: In comparison to other IOL formulas, the PEARL-DGS resulted in better refractive outcomes after cataract surgery in post-myopic laser refractive corneal surgery eyes without constant optimization. We suggest that PEARL-DGS be considered as the first choice for IOL power calculation in these eyes when the clinicians do not have their optimized constants.

Four-flanged polypropylene optic piercing technique for scleral fixation of multifocal intraocular lens.

BACKGROUND: To evaluate the feasibility of creating flanges using an optic piercing technique with a 6 - 0 polypropylene monofilament for scleral fixation of dislocated one-piece diffractive multifocal intraocular lenses (IOLs). STUDY DESIGN: Experimental study and case series. SUBJECTS: Optical bench test and eyes with IOL dislocation. METHODS: Two separate 6 - 0 polypropylenes were penetrated twice at the opposite peripheral optic of the TECNIS Synergy IOL (Johnson & Johnson Vision). The root mean square of the modulation transfer function (MTFRMS), at between + 1.00 and - 4.00 D of defocus, was measured in the TECNIS Synergy IOL both with and without optic piercing in the optical bench study. This case series included three eyes from two patients who underwent scleral-fixation of multifocal IOLs using the four-flanged polypropylene optic piercing technique. The postoperative corrected distance visual acuity (CDVA) at 4 m, the uncorrected near visual acuity (UNVA) at 40 cm, and IOL centration were evaluated. RESULTS: The optical bench test showed no differences in MTFRMS values measured in the TECNIS Synergy IOL, either with or without optic piercing at all defocuses. In all three case series, the postoperative CDVA at 4 m was 20/20 and UNVA at 40 cm was J1. Postoperative anterior segment photographs showed good centration of IOLs in all cases. CONCLUSION: The four-flanged polypropylene optic piercing technique for multifocal IOL scleral fixation can provide excellent clinical outcomes and IOL stability after surgery without diminishing the performance of the multifocal IOLs.

Actual anterior-posterior corneal radius ratio in eyes with prior myopic laser vision correction according to axial length.

We retrospectively evaluate the actual anterior-posterior (AP) corneal radius ratio in eyes with previous laser correction for myopia (M-LVC) according to axial length (AL) using biometry data exported from swept-source optical coherence tomography between January 2018 and October 2021 in a tertiary hospital (1018 eyes with a history of M-LVC and 19,841 control eyes). The AP ratio was significantly higher in the LVC group than in the control group. Further, it was significantly positively correlated with AL in the LVC group. We also investigated the impact of the AP ratio, AL and keratometry (K) on the absolute prediction error (APE) in 39 eyes that underwent cataract surgery after M-LVC. In linear regression analyses, there were significant correlations between APE and AL/TK, while APE and AP ratio had no correlation. The APE was significantly lower in the Barrett True-K with total keratometry (Barrett True-TK) than in the Haigis-L formula on eyes with AL above 26 mm and K between 38 and 40 D. In conclusion, in eyes with previous M-LVC, AP ratio increases with AL. The Barrett True-K or Barrett True-TK formulas are recommended rather than Haigis-L formula in M-LVC eyes with AL above 26 mm and K between 38 and 40D.

Clinical Outcomes of Intrascleral Fixation of Intraocular Lens Compared to Ciliary Sulcus Implantation and Transscleral Fixation.

PURPOSE: To compare the clinical outcomes of intrascleral fixation of the three-piece intraocular lenses (IOLs) 2.5 mm posterior to the limbus with ciliary sulcus implantation and transscleral fixation 2.5 mm posterior to the limbus. METHODS: Sixty-five eyes of 65 patients who underwent ciliary sulcus implantation or transscleral or intrascleral fixation of the AMO Sensar AR40e IOL were retrospectively reviewed. The postoperative refractive prediction error, back-calculated effective lens position (ELP), corrected distance visual acuity (CDVA), and postoperative residual cylinder were compared. RESULTS: There were significant differences in the median (interquartile range) postoperative refractive prediction error (diopters [D]) among the three groups (p < 0.001): for ciliary sulcus implantation (33 eyes), -0.89 D (-1.21 to -0.56 D); for transscleral fixation (10 eyes), -0.40 D (-0.78 to -0.22 D); and for intrascleral fixation (22 eyes), 0.01 D (-0.28 to 0.34 D). Significant differences (p < 0.001) were observed in the median back-calculated ELP: for ciliary sulcus implantation, 4.35 mm (3.95 to 4.55 mm); for transscleral fixation, 4.51 mm (4.34 to 4.76 mm); and for intrascleral fixation, 4.90 mm (4.56 to 5.35 mm). There were no differences in the median postoperative CDVA (0, 0.10, and 0 logarithm of the minimum angle of resolution, respectively; p = 0.083) and the residual cylinder (-0.75, -1.50, and -0.63 D, respectively; p = 0.074) among three groups. CONCLUSIONS: Intrascleral fixation showed no myopic shift and the most posterior lens position, while ciliary sulcus implantation induced the greatest myopic shift and the most anterior lens position. However, there was no significant difference in the postoperative CDVA or astigmatism among the eyes with different IOL insertion methods, demonstrating good IOL stability and vision outcomes.

New technology using crystalline lens autofluorescence for presbyopia and cataract grading.

PURPOSE: To investigate whether fundus autofluorescence (FAF) obtained using an ultra-wide field (UWF) fundus camera with an artificial opacity pattern can grade the degree of presbyopia and nuclear cataract. METHODS: Sixty eyes of 30 patients were enrolled in this prospective diagnostic study. The nuclear cataract (nuclear color/opalescence (NC/NO)) was graded according to the Lens Opacity Classification System III. The monocular near point of accommodation (NPA) was measured in eyes with NC3/NO3 or less. The mean gray value difference between the central 8 artificial opacity lesions and peripheral 8 artificial opacity lesions in the retinal AF was measured. The correlation between the mean gray value difference, NPA, and nuclear cataract grade was analyzed. RESULTS: The mean nuclear cataract grade of 60 eyes was 3.2 ± 1.6 and mean NPA of 37 eyes was 45.3 ± 16.1 cm. The mean gray value differences increased with increasing nuclear cataract grade (eyes with NC/NO grade 1, 53.3 ± 11.4; 2, 78.3 ± 13.6; 3, 95.2 ± 12.2; 4, 101.6 ± 11.9; 5, 109.0 ± 22.9; and 6, 121.1 ± 12.0; p < 0.001). The mean gray value difference was positively correlated with both the monocular NPA (R2 = 0.637; ß coefficient = 1.009; 95% CI, 0.748 to 1.271; p < 0.001) and nuclear cataract grade (R2 = 0.661; ß coefficient = 12.437; 95% CI, 10.097 to 14.778; p < 0.001). CONCLUSIONS: The FAF camera with an artificial opacity pattern attached can be used to effectively diagnose the degree of presbyopia and nuclear cataract.

Clinical Characteristics and Therapeutic Outcomes of Pediatric Blepharokeratoconjunctivitis.

PURPOSE: The purpose of this study was to determine the clinical characteristics, disease course, therapeutic outcomes, and prognostic factors for pediatric patients with blepharokeratoconjunctivitis (BKC). METHODS: A retrospective medical chart review was performed for patients aged 15 years or younger who had been diagnosed with BKC between 2004 and 2020 at 2 tertiary hospitals in Korea. The following data were collected: demographics, medical history, ocular findings, geometric profiling of corneal lesion, medical management, and outcomes. RESULTS: A total of 137 patients (90 female and 47 male) were included. The patients' mean age was 8.3 ± 3.8 years at disease onset. Both eyes were involved in 57.7% of cases. The most common corneal lesion was corneal neovascularization (77.4%), followed by clinically visible corneal infiltration (51.8%) and stromal scarring (43.1%). Most of the corneal lesions involved a single quadrant, most commonly the inferior quadrant. After treatment, disease remission was achieved in 95% of patients, and visual acuities improved from 0.2 ± 0.3 logarithm of minimal angle of resolution at disease presentation to 0.1 ± 0.3 logarithm of minimal angle of resolution at final follow-up ( P = 0.001). Recurrence occurred in 52.6% of patients. Cylinder power was significantly higher in patients with recurrence than in those without. The number of cases of recurrence was positively associated with final cylinder power. CONCLUSIONS: Although the treatment induced disease remission in 95% of children with BKC, recurrence occurred in 52.6% of those cases. Because recurrence resulted in significant astigmatism, careful observation for recurrence and prompt management are warranted for preservation of vision in pediatric patients with BKC.

Differences in vulnerability to desiccating stress between corneal and conjunctival epithelium in rabbit models of short-term ocular surface exposure.

We evaluate the difference in vulnerability to desiccating stress (DS) between the corneal and conjunctival epithelia to understand different ocular surface staining patterns in dry eye patients. We generated a rabbit model of short-term exposure keratopathy. To induce DS in the ocular surface, rabbit right eyelids were opened for 30 min, with blinking once/minute. Corneal staining scores increased from 3-min post-DS exposure, while conjunctival staining increased from 20-min post-DS. At 20 min, the tear MUC5AC level doubled as compared to pre-DS (p = 0.007). In Western blot analysis, conjunctival AQP5, MUC5AC, and CFTR expression increased significantly in response to DS, compared to control (p = 0.039, 0.002, 0.039, respectively). Immunohistochemistry for CD31 and LYVE-1 were performed. CD31-positive cells and lymphatic space surrounded by LYVE-1-positive cells increased significantly in conjunctival tissue post-DS, compared to control (p = 0.0006, p < 0.0001, respectively). Surface damage was worse in the corneal than in the conjunctival epithelium after DS, by scanning electron microscopy. This study showed that the cornea and conjunctival epithelium show differences in vulnerability to DS. Increased blood vessels and dilated lymphatics, accompanied by increased conjunctival epithelial AQP5, MUC5AC, and CFTR expression, underlie the protective mechanism of the conjunctiva to desiccating stress.

The Effect of Professional Oral Care on the Oral Health Status of Critical Trauma Patients Using Ventilators.

BACKGROUND: Oral care reduces the incidence of ventilator-associated pneumonia. In addition, it is important that critically ill patients to maintain their oral health in order to restore their quality of life and to receive adequate nutrition after recovery. OBJECTIVE: The purpose of this study was to evaluate the effect of professional oral hygiene care (POHC) on the oral health status of patients using a ventilator. METHODS: Fifty-seven ventilated trauma patients were admitted to a tertiary medical institution. For 5 days, the dental hygienist performed POHC every 24 h along with routine oral hygiene care (ROHC) every 8 h for the experimental group (Exp.) (n = 29), whereas only ROHC was provided the control group (Cont.) (n = 28). Oral health status was evaluated using a modified bedside oral exam (MBOE). RESULTS: There was no significant difference between the two groups in the total MBOE score up to 48 h after admission. However, the difference between the two groups was significant for MBOE (F = 16.10, p = 0.000), gingiva (F = 6.02, p = 0.018), buccal mucosa (F = 4.21, p = 0.046), and dental plaque score after 72 h (F = 13.15, p = 0.000). CONCLUSION: This study confirms the importance of POHC in improving the oral health.

Correlations between clinical parameters of dry eye disease and serologic profiles in Sjögren's syndrome.

PURPOSE: To investigate the difference in clinical parameters of dry eye disease (DED) according to the presence of serum anti-La antibodies and evaluate the correlations of autoantibody titers with DED parameters in patients with primary Sjögren's syndrome (pSS). METHODS: Sixty-two patients diagnosed with pSS according to the 2016 ACR-EULAR classification criteria were classified into two groups depending on the presence of anti-La antibodies: group 1 (anti-Ro positive alone, n = 31) and group 2 (both anti-Ro and anti-La positive, n = 31). DED parameters (conjunctival and corneal ocular staining score (OSS), tear film break-up time (TBUT), Schirmer I test, lipid layer thickness (LLT), meiboscore, and ocular surface disease index), serum autoantibodies (anti-Ro, anti-La, rheumatoid factor (RF), and antinuclear antibody) and focus score were assessed. RESULTS: The DED parameters were not significantly different between the two groups (P > 0.05). The anti-Ro titers, RF-positive rate, and the focus score were significantly higher in group 2 than in group 1 (P = 0.001, P = 0.049, P = 0.001, respectively). The anti-Ro titers had a significant positive correlation with conjunctival OSS (r = 0.273, P = 0.033) and the focus score had a positive correlation with LLT and meiboscore (r = - 0.358, P = 0.072; r = 0.379, P = 0.056). CONCLUSION: In this study, anti-Ro titers significantly correlated with conjunctival staining score, whereas anti-La did not statistically correlated with clinical DED parameters in SS. Meanwhile, anti-Ro titers and focus score were significantly higher in patients positive for both anti-Ro and anti-La, which suggests that examining anti-La with anti-Ro would be helpful in predicting clinical severities of SS patients.

Quantitative analysis of morphological and functional alterations of the meibomian glands in eyes with marginal entropion.

PURPOSE: To quantitatively analyze morphological and functional alterations of the meibomian glands in eyes with marginal entropion and their changes after surgery. METHODS: Sixty eyes of 52 patients with marginal entropion and underwent meibography and interferometer were included. One-hundred and seventeen age- and sex-matched eyes with minimal to mild meibomian gland dysfunction (MGD) were recruited as control eyes. Meibomian gland loss (MGL) and lipid layer thickness (LLT) were compared between eyes with marginal entropion and control eyes. Subgroup analysis was performed according to the extent of entropion. MGL and average LLT at 1 and 5 months after surgery were compared with those of 20 eyes with marginal entropion followed without surgery. RESULTS: In eyes with marginal entropion, MGL was higher (27.7% vs. 12.8%, P = 0.014), and average LLT was thinner (64 nm vs. 86 nm, P = 0.005) than those in control eyes. MGL was higher in eyes with more extensive entropion (> 2/3 eyelid width) than in eyes with less extensive entropion (≤ 1/3 eyelid width) (40.5% vs. 13.2%, P = 0.001). Average LLT increased after surgery (97 nm at 1 month, P = 0.003; 75 nm at 5 months, P = 0.319), and thicker than that of eyes followed without surgery (97 nm vs. 66 nm, P = 0.046). MGLs after surgery remained unchanged from the preoperative MGL (all P > 0.7). CONCLUSION: Marginal entropion is associated with morphological and functional alterations of the meibomian glands. Functional improvement after entropion repair suggests that marginal entropion could cause or exacerbate MGD. Further studies are required to establish the role of entropion repair in managing MGD.

Relapsed acute myeloid leukemia presenting as conjunctival myeloid sarcoma: a case report.

BACKGROUND: Conjunctival myeloid sarcoma (MS) as an isolated presentation of acute myeloid leukemia (AML) relapse is rare. Here, we report a case of unilateral conjunctival MS revealed as a sign of AML relapse. CASE PRESENTATION: A 50-year-old man with a history of AML in remission visited our clinic presenting with a left conjunctival injection persisting for 1 month. Diffuse subconjunctival thickening with conjunctival vascular engorgement was observed. Ultrasound biomicroscopy revealed a hyper-reflective, thickened conjunctiva in his left eye. During the incisional biopsy, the lesion was strongly attached to the underlying sclera; histopathologic examination revealed infiltration of leukemic blasts. The relapse of AML was confirmed by a successive bone marrow biopsy. The ocular lesion disappeared after allogeneic peripheral blood stem cell transplantation (PBSCT) and concomitant salvage radiotherapy on the left eye. The patient has remained in remission for 3 years after allogeneic PBSCT. CONCLUSIONS: Incidental conjunctival lesions can indicate AML relapse in patients treated earlier for AML. An ophthalmologist may have a role in the early detection of AML when a patient presents with an atypical conjunctival lesion.

The influence of professional oral hygiene care on reducing ventilator-associated pneumonia in trauma intensive care unit patients.

Aim This study aimed to examine the effects of professional oral hygiene care for the prevention of ventilator-associated pneumonia (VAP) and the improvement of oral hygiene among patients in the trauma intensive care unit (TICU).Materials and methods TICU patients who underwent intubation were randomly assigned to either the experimental group (n = 29) or control group (n = 28). The developed professional oral hygiene care protocol was administered to patients in the experimental group every 24 hours. Additionally, data regarding general characteristics, medical history, oral hygiene status, Clinical Pulmonary Infection Score and quantitative polymerase chain reaction were assessed.Results The incidence of VAP differed between the control group (10.58) and experimental group (0) post intervention. Post-admission bedside oral exam scores with significant differences in oral hygiene were observed in the experimental group (in contrast to the control group) from 48 hours onwards (10.69 ± 3.43, p = 0.06). Staphylococcus aureus and Klebsiella pneumoniae exhibited significant differences in count as professional oral hygiene care continued.Conclusions This study suggests a model in which different health care professionals can cooperate to reduce the incidence of VAP and improve oral health conditions.

Risk of Stroke or Acute Myocardial Infarction in Subconjunctival Hemorrhage: A Nationwide Cohort Study.

PURPOSE: To investigate whether subconjunctival hemorrhage (SCH) raises the risk of subsequent stroke or acute myocardial infarction (AMI) in the general population. METHODS: Using the National Health Insurance Service-National Sample Cohort database records from 2002 to 2013. Of 1,025,340 individuals in the database, we included 703,090 aged ≥ 20 years old without any history of SCH, cerebrovascular diseases, and ischemic heart diseases in the analyses. Of these, we identified 46,251 cases of incident SCH and regarded it as a time-varying covariate. We performed sensitivity analyses using 1:4 propensity score (PS)-based matched controls. To adjust for potential confounders, we investigated Cox regression models using defined demographic information, comorbidities, co-medications, and the Charlson Comorbidity Index score. RESULTS: The SCH group showed higher incidence probability of stroke or AMI than the general population (3.17% versus 2.71%, respectively; p < .001); however, when compared to the PS-based matched controls, there was no difference (3.17% versus 3.03%, respectively; p = .76). Time-varying covariate Cox regression analyses without adjusting for confounders showed that SCH was associated with increased risk of subsequent stroke or AMI; however, after adjusting for confounders, SCH did not increase the risk of stroke or AMI. CONCLUSION: This population-based cohort study showed that SCH itself is not a risk factor for stroke or AMI. Clinicians could reassure patients with SCH that it would not increase the risk for stroke or AMI. We recommend attentive evaluation of underlying diseases for patients with SCH for identifying risk factors of stroke or AMI.

Clinical Outcomes of In-office Sutureless Amniotic Membrane Transplantation in Persistent Epithelial Defect.

PURPOSE: To investigate the efficacy of outpatient clinic-based sutureless amniotic membrane transplantation (AMT) along with therapeutic contact lens (T-lens) application in eyes with persistent epithelial defects (PED). METHODS: Nine eyes of nine patients (mean age, 71.7 ± 5.2 years) diagnosed with PED and treated with in-office sutureless AMT combined with T-lens application were retrospectively reviewed. Demographics, systemic diseases, PED etiology, corneal epithelial defect size, visual acuity, corneal scraping culture results, and clinical course were evaluated. RESULTS: Among nine eyes with PED, three had neurotrophic keratopathy, four had infectious keratitis (three with fungal keratitis and one with bacterial keratitis), one had limbal deficiency, and one had marginal keratitis. The mean epithelial defect size (calculated as an average of the horizontal and vertical diameters) was 3.13 ± 1.42 mm, and the mean duration from AMT to epithelial healing was 30.1 ± 10.5 days (range, 14-51 days) in successful trials. The success rates were 77.8% (7/9) per patient and 66.7% (8/12) per trial. The causes of failure in two patients were AMT displacement and uncontrolled infection. CONCLUSIONS: Our results demonstrate that in-office sutureless AMT combined with T-lens application can be used in patients with PED who are refractory to medications. It will be especially helpful for elderly patients because of its easy-to-use method. To achieve successful outcomes with AMT, an appropriate periocular environment as well as infection control need to be considered.

Oral health status of inpatients with varying physical activity limitations in rehabilitation wards: A cross-sectional study.

ABSTRACT: Poor oral hygiene can be potentially life-threatening in inpatients. However, no basic protocol on oral hygiene customized for inpatients exists, and lack of oral care related knowledge, attitude, and skills among caregivers could be detrimental to the general health of patients. This study sought to identify the oral care practices and oral health status of inpatients with varying physical activity limitations in a rehabilitation ward.Sixty-one inpatients in a rehabilitation ward were evaluated for their medical and physical conditions and oral health status. These were assessed using the bedside oral exam, decayed, missing, filled teeth index, plaque index, gingival index, and caries activity test.In total, 40 men and 21 women (mean age, 56.6 years) were included in this study. Among them, 50.8% of the patients could brush their teeth unassisted, whereas 49.2% required assistance from an assistant for oral care. The proportion of patients receiving nasogastric tube feeding was higher in the group that could not provide oral self-care; 36.7% and 33.3% of these patients showed moderate and severe dysfunction, respectively, based on bedside oral exam. Scores for the swallowing, tongue, and total domains of bedside oral exam were poorer for patients who could not provide oral self-care (P < .01). The caries activity test indicated a moderate risk for both groups.Our findings suggest that an oral care protocol that considers the physical activity limitations in inpatients in rehabilitation wards is necessary to minimize negative influences on the systemic health of these patients.

Association between sleep habits and symptoms of oral disease in adolescents: the 2017 Korea Youth Risk Behavior Web-based Survey.

BACKGROUND: This cross-sectional study aimed to examine the relationship between sleep habits and oral disease symptoms in adolescents. METHODS: Among 62,276 adolescents who participated in the 13th Korea Youth Risk Behavior Web-based Survey (2017), we selected a total of 54,766 adolescents (age, 12-18 years; male, 49.9%) for the final analysis, after excluding those who did not report their sleep duration. The 13th Korea Youth Risk Behavior Web-based Survey data were obtained from a stratified, multistage, clustered sample. Independent variables included general characteristics, oral health behavior, sleep types, sleep duration, and sleep quality; dependent variables comprised oral disease symptoms. Sleep was categorized according to bedtime astype A (bedtime < 1 a.m.) and type B (bedtime ≥ 1 a.m.). Data were analyzed using logistic regression analysis. Statistical significance was set at p < 0.05. RESULTS: After adjusting for all covariates, adolescents with type A sleep had a higher risk of toothache on chewing (OR = 1.08, 95% CI 1.02-1.15) than adolescents with type B. Adolescents who slept for 6 h or less each night had a higher risk of pain in the tongue and buccal mucosa (OR = 1.35, 95% CI 1.18-1.54), gingival pain, and bleeding (OR = 1.31, 95% CI 1.19-1.45) than those who slept for more than 8 h. Adolescents with low quality of sleep had a higher risk of toothache or throbbing (OR = 1.70, 95% CI 1.60-1.81), toothache on chewing (OR = 1.73, 95% CI 1.65-1.82), and halitosis (OR = 1.51, 95% CI 1.41-1.59) than those with high quality of sleep. CONCLUSIONS: Our findings indicate that some oral symptoms are related to sleep duration and quality. It is essential to inculcate good sleeping habits in adolescents by emphasizing the effects of inadequate sleep duration and quality.

Characteristics of dry eye patients with thick tear film lipid layers evaluated by a LipiView II interferometer.

PURPOSE: To investigate the characteristics of eyes with dry eye disease (DED) whose lipid layer thickness (LLT) measured 100 nm on a LipiView II interferometer and compare the DED parameters of them to those with LLT below 100 nm. METHODS: A total of 201 eyes of 102 enrolled DED patients (mean age 56.4 ± 11.8 years) were classified into 3 groups according to their average LLT; < 60 nm as thin-LLT (n = 49), 60-99 nm as normal-LLT (n = 77), and 100 nm as thick-LLT (n = 75). LLT, meiboscore, Schirmer I test, tear film break-up time (TBUT), ocular surface staining (OSS), and ocular surface disease index (OSDI) were assessed. RESULTS: The OSS and TBUT were significantly worse in the thick-LLT group than in the normal-LLT group (p = 0.020, and p = 0.028, respectively). The OSDI was significantly higher in the thick-LLT group than in the thin-LLT group (p = 0.006). However, the meiboscore was not different among the three groups (p = 0.33). Age, OSS, and OSDI showed a positive correlation with LLT (r = 0.16, p = 0.023; r = 0.213, p = 0.003; and r = 0.338, p = 0.001, respectively). In sensitivity analyses, eyes with corneal erosions had a significantly higher average LLT (p = 0.015), higher OSDI (p = 0.009), shorter TBUT (p < 0.001), and shorter Schirmer I value (p = 0.024) than those with clear corneas. CONCLUSION: The average LLT of eyes with corneal erosions was thicker than those without erosions, suggesting that the LLT of 100 nm in the eyes with corneal erosions should not be regarded as a stable physiologic condition. Cautious interpretation of LLT along with other dry eye parameters is required.
