Background/Objectives Although lifestyle habits may represent modifiable risk factors of glaucoma, the association between lifestyle factors and glaucoma is not well understood. The aim of this study was to investigate the association between lifestyle habits and the development of glaucoma. Subjects/Methods Participants who underwent health check-ups from 2005 to 2020 using a large-scale administrative claims database in Japan were included in the study. Cox regression analyses were performed where glaucoma development was regressed on the lifestyle (body mass index, current smoking, frequency and amount of alcohol consumption, eating habits, exercise habits and quality of sleep), age, sex, hypertension, diabetes mellitus and dyslipidaemia. Results Among the 3,110,743 eligible individuals, 39,975 developed glaucoma during the mean follow-up of 2058 days. Factors associated with increased risk of glaucoma were overweight/obese (vs. moderate weight: hazard ratio, 1.04 [95% confidence interval, 1.02–1.07]), alcohol consumption of 2.5–4.9 units/day, 5–7.4 units/day, and ≥7.5 units/day (vs. Conclusions Moderate body mass index, having breakfast, avoiding late dinner, limiting alcohol intake to

Background We investigated the effect of the number of laser shots applied on the myopic variables to elucidate the mechanism of myopia development in laser-treated retinopathy of prematurity (ROP) eyes. Methods A total of 33 eyes of 17 infants with ROP who underwent laser treatment were included in the analysis. Cycloplegic retinoscopic refraction testing was carried out and the spherical equivalent (SE) was calculated. Relationships between SE and various variables (including the number of laser shots applied) were examined. In addition, an age-matched control group without ROP was prepared and ocular structural parameters were compared. Results Although there was no statistical difference in axial length (AL) between two groups (p = 0.88), SE was significantly more myopic in the ROP group (p Conclusions In laser-treated ROP eyes, AL, CR, and CLP were related to the degree of myopia. Moreover, the number of shots applied also affected the myopic status in laser-treated ROP eyes. Among AL, CR, and CLP, only CLP was correlated with the laser shots applied.

To clarify recent trends in glaucoma surgery in Japan, including minimally invasive glaucoma surgery.Retrospective cohort study.We used the Diagnostic Procedure Combination database, a nationwide administrative database in Japan. Patients who underwent glaucoma-related procedures were included. We calculated the number of surgeries stratified by procedures and age categories. We also investigated the number of glaucoma-related procedures in combination with cataract surgery.From fiscal years 2011 to 2019, we identified 134,331 glaucoma-related procedures at 720 hospitals. The total number of glaucoma-related procedures increased by 215% from 6516 in 2011 to 20,569 in 2019. The numbers of filtering surgeries, trabeculotomies, and glaucoma drainage devices with plates [GDD(p +)] procedures significantly increased (P = 0.002, 0.002, and 0.006, respectively), whereas the number of cyclocryotherapy procedures significantly decreased (P = 0.002). The number of iStent procedures increased by 49% from 371 in 2018 to 551 in 2019. The ≥ 65 year age group accounted for 80% of the iStent procedures. In the 0 to 14 year age group, trabeculotomy accounted for about 70% of the procedures, and the GDD(p +) procedure became the second most common procedure after trabeculotomy because of the decrease in filtering surgeries. Among combination surgeries, trabeculotomy was most frequently performed. The proportion of combination surgery increased, especially in trabeculotomy.The total number of glaucoma-related procedures increased throughout the observation period. Before 2017 filtering surgery was the most common procedure, whereas trabeculotomy was most common after 2018. The proportion of trabeculotomies performed in combination with cataract surgery continuously increased.

To investigate the outcomes of fornix-based trabeculectomy in Japanese patients with glaucoma based on more than five years of preoperative data.Retrospective case series METHODS: This study consisted of 35 eyes of 35 Japanese glaucoma patients (mean age: 60.6, standard deviation (SD) 11.5 years) who received initial fornix-based trabeculectomy from a single ophthalmology clinic, with one or more reliable visual field test results per year from at least five years before and after the surgery. Measurements included postoperative mean intraocular pressure (IOP), standard deviation of IOP, medication scores, mean deviation slope, and total deviation slope were evaluated based on preoperative data. The relationship between mean IOP, SD-IOP and the visual field (VF) deterioration speed was also analysed.The mean follow-up period before surgery was 6.15 (SD 0.97) years and post surgery it was 5.95 (SD 0.63) years. The preoperative mean IOP of 14.6 (SD 2.3) mmHg significantly decreased to 9.2 (SD 2.2) mmHg (P.001). The preoperative medication score 2.7 (SD 0.5) significantly decreased to 0.1 (SD 0.4, P.001). The preoperative MD slope of -0.52 (SE 0.047) dB/year significantly improved to -0.31 (SE 0.14) dB/year (P.01), with improvement in the superior hemifield (P ≤.018). Inferior hemifield (P.10) did not follow the trend. Neither mean IOP nor SD-IOP correlated with the VF deterioration speed.Fornix-based trabeculectomy is an acceptable procedure for initial surgical management of glaucoma, especially for maintenance of superior VF.

To evaluate the relationship between the number of laser shots applied during laser photocoagulation treatment and the degree of myopia at 3 years in children with laser-treated retinopathy of prematurity (ROP). A total of 68 eyes of 34 infants who had developed prethreshold ROP and were treated by diode laser therapy were included in the current study. Cycloplegic retinoscopic refraction testing was performed in the children at the age of 3 years, and the spherical equivalent (SE) was calculated for all the examined eyes. The number of laser shots that had been applied was compared between the eyes with and without high myopia (SE < − 5 diopters (D)). In addition, the relationship between the difference in the SE values between the two eyes in each infant and the difference in the number of laser shots applied between the two eyes was also analyzed. The number of laser shots applied was significantly higher for the eyes with high myopia than for those without high myopia (p = 0.0088), and the number of laser shots applied was significantly positively correlated with the degree of myopia (p < 0.001). A significant correlation was also observed between the differences in the SE values between the two eyes and the differences in the number of laser shots applied between the two eyes (p = 0.0013). The number of laser shots applied in photocoagulation treatment for ROP is significantly associated with the degree of myopia seen subsequently in the children.

Non-vascularized pigment epithelial detachments (PED) are usually associated with dry age-related macular degeneration (AMD). In this study, we aimed to investigate the correlation between visual function and morphologic parameters. Seventeen eyes of eleven patients with non-vascularized AMD were enrolled. In addition to conventional optical coherence tomography (OCT), polarization-sensitive optical coherence tomography (PS-OCT) measurements were performed by evaluating the regularity of retinal pigment epithelium (RPE) entropy within the PED area. Retinal sensitivity was measured with MP-3 microperimetry, and retinal sensitivities within (RSin) and outside (RSout) the PED area were calculated. The relationship between OCT parameters and visual function was analyzed. As a result, there was a significant difference between the RSin and RSout (p < 0.001, Wilcoxon signed rank test). Moreover, RSin was significantly related to logMAR VA (p = 0.033, linear mixed model). The regularity of RPE entropy was significantly related to visual acuity and RSin (p = 0.00038, p = 0.031, linear mixed model), although neither the height nor area of PED correlated with visual function. Our results suggest that retinal sensitivity is significantly deteriorated within the PED area and RPE entropy measured with PS-OCT was closely related to visual function in eyes with non-vascularized PED.

Central serous chorioretinopathy (CSC) usually resolves spontaneously; however, in some patients, it can be chronic and visual impairment remains even after resolution of the serous retinal detachment. The impaired photoreceptor cells often present with disrupted ellipsoid zone (EZ) on optical coherence tomography (OCT). In this study, the integrity of EZ was quantified by calculating the index of residual EZ, identified on binarized OCT images from 25 eyes of 23 patients with resolved CSC. To estimate residual EZ, integrity of residual EZ with the central horizontal line on the fovea (rEZc) and average integrity of residual EZ within 3 × 3-mm macular area (rEZave) were investigated. The interrater reliability of the method was assessed using the intraclass correlation coefficient (ICC). The relationship between LogMAR VA and age, central retinal thickness, central choroidal thickness, rEZc, and rEZave were evaluated using the linear mixed model. Retinal sensitivity was measured with the MP-3 microperimeter and similar analyses were iterated for mean retinal sensitivity (MS). ICC values were 0.938 with rEZc and 0.979 with rEZave. rEZc was significantly related to LogMAR VA (p = 0.039). rEZave was significantly related to MS (p
