Aim: Although the awareness of disasters has increased among nurses, the concept of disaster preparedness and response has not been sufficiently explored with undergraduate nursing students. The aim of this study was to assess and compare the perceptions of students regarding disaster preparedness and response that live in different earthquake-prone cities; Istanbul, Turkey and Miyazaki, Japan. Methods: A cross-sectional study employing seven questions was conducted in a final group of 1053 nursing students from Istanbul, Turkey, and Miyazaki, Japan. Results: Most study respondents were female, aged 18-22years, with a high proportion of second year students in both cities. Istanbul's students had more knowledge about disaster preparedness and response in relation to age and year of university, showing statistically significant differences. Istanbul's highest rated responses to disaster characteristics were on structural elements and injuries/deaths, while Miyazaki's was "unpredictable/sudden/disorganized". Respondents in Istanbul identified earthquakes as the disaster most likely to occur, while respondents in Miyazaki identified typhoon/hurricane. Study participants responded that they could provide caregiver roles during a disaster event rather than triage or managerial roles as disaster responders. Conclusion: Disaster characteristics were not described by one third of the students. Of the two-thirds that were described, most were of events that were highly predictable because of their frequencies in the given areas. Universities need to target and then focus on high-risk factors in their areas and have disaster plans for students who can provide triage and managerial nursing roles as disaster responders. © 2014 The Authors.

Purpose: To determine the incidence and the factors that can cause a reopening of a macular hole (MH) after a surgical closure. Design: Retrospective, comparative, consecutive case series. Methods: The medical charts of all patients who underwent vitrectomy with or without internal limiting membrane (ILM) peeling for an idiopathic full-thickness MH were reviewed. In all cases, the MH was closed successfully. Simultaneous phacoemulsification with intraocular lens implantation was performed on all phakic patients who were older than 40 years. Results: Eight hundred and seventy-seven eyes of 831 patients with a mean age of 64.9 ± 8.0 years were studied. Combined cataract extraction with vitrectomy was performed on 763 eyes of 775 phakic eyes. The mean follow-up time after MH surgery was 57.7 ± 38.4 months (range, 1 to 175 months). Two groups were studied: an ILM-off group (n = 514) and an ILM-on group (n = 363). The MH reopened in 2 eyes (0.39%) in the ILM-off group and in 26 eyes (7.2%) in ILM-on group (P < .0001). Kaplan-Meier analysis showed higher rates of reopening in the ILM-on group than in the ILM-off group (P< .0001, log-rank test). Factors related to the reopening in the ILM-on group were refractive error (r = -0.12; P = .049) and intraoperative peripheral tear formation (r = 0.13; P = .018). Conclusions: ILM peeling significantly decreases the incidence of the reopening of an MH. Although the pathogenesis of the reopening of MHs is still undetermined, myopia and intraoperative retinal tears may be related to the reopening. © 2010.

PURPOSE:: The purpose of this study was to determine the factors that are correlated with the visual outcomes in patients who underwent pars plana vitrectomy with internal limiting membrane peeling for myopic foveoschisis (MF). METHODS:: In this retrospective, interventional consecutive case series, 39 eyes of 39 consecutive patients who had undergone pars plana vitrectomy with internal limiting membrane peeling for MF were studied. Preoperative optical coherence tomography showed that none of the eyes had a macular hole or vitreoretinal traction. Eyes were divided into those with MF and a foveal detachment (FD; FD group, n = 27) and those with MF without an FD (no-FD group, n = 12). The main outcome measures were best-corrected visual acuity (BCVA) and the optical coherence tomography findings. RESULTS:: Optical coherence tomography showed a complete resolution of the MF with a reattachment of the fovea in all eyes, and the retina remained attached during the mean follow-up of 41 months. The final mean BCVA improved significantly in the FD group (P = 0.0003) but not in the no-FD group (P = 0.56). The final BCVA of the FD group and no-FD group improved in 70% and 42%, remained unchanged in 26% and 33%, and worsened in 4% and 25% of the eyes, respectively. A better final BCVA was significantly correlated with a better preoperative BCVA (P < 0.0001), a shorter axial length (P = 0.045), and the presence of an FD (P = 0.028). CONCLUSION:: Pars plana vitrectomy with internal limiting membrane peeling results in long-term favorable anatomical and visual outcomes. Eyes with an FD may be good candidates for surgery.

Purpose: To evaluate the effectiveness of intravitreous bevacizumab (Avastin), intravitreous tissue plasminogen activator, and vitrectomy for the macular edema secondary to branch retinal vein occlusion. Methods: Retrospective, interventional case series. We studied 228 eyes of 228 patients. Forty-one eyes received 1.25 mg of intravitreous bevacizumab, 71 eyes received tissue plasminogen activator, and 116 eyes underwent vitrectomy. A reinjection of 1.25 mg of bevacizumab was based on the morphologic and functional findings. The main outcome measures were the best-corrected visual acuity and optical coherence tomography-determined foveal thickness. Results: The mean postoperative follow-up period was 32.2 months with a range of 12 months to 69 months. The mean number of intravitreous bevacizumab was 2.8 with a range of 1 to 5. The mean best-corrected visual acuity and foveal thickness significantly improved after all 3 treatments, and the differences in the best-corrected visual acuity between the 3 groups were not significant at 12 months. Fourteen eyes (34%) in the intravitreous bevacizumab group and 21 eyes (30%) in the tissue plasminogen activator group required additional surgeries. Conclusion: The 3 treatments appear to provide similar visual outcomes at 12 months. However, in some eyes treated with intravitreous bevacizumab or tissue plasminogen activator, additional surgeries were required, and a longer follow-up period was required to determine the final outcome. © The Ophthalmic Communications Society, Inc.

Purpose: To evaluate the effect of pars plana vitrectomy (PPV) either with or without internal limiting membrane (ILM) peeling for macular edema associated with macular vein occlusion (MVO). Methods: In this retrospective, interventional, comparative case series study, 41 patients (41 eyes) underwent PPV either with or without ILM peeling for macular edema due to MVO. Twenty-eight eyes without ILM peeling (PPV alone) were compared with 13 eyes with ILM peeling (ILM-off). The main outcome measures were best-corrected visual acuity (BCVA) and foveal thickness, evaluated by optical coherence tomography. Results: Baseline demographic characteristics of the two groups were similar. Postoperative follow-up period ranged from 12 to 53 months (mean, 27.9 months). The postoperative mean BCVA improved and foveal thickness decreased significantly in both groups. The difference in BCVA between the two groups was not significant at any time point. The mean foveal thickness in the ILM-off group was thicker than that in the PPV alone group during the follow-up period. No patient had severe intraoperative or postoperative complications. Conclusion: PPV either with or without ILM peeling may improve the anatomical and functional outcomes of macular edema secondary to MVO. Removal of the ILM does not appear to affect visual outcome; however, it may not reduce the foveal thickness as much as PPV alone. © 2010 Japanese Ophthalmological Society (JOS).

Purpose: To determine the retinal thickness (RT), after vitrectomy with internal limiting membrane (ILM) peeling, for an idiopathic macular hole (MH) or an epiretinal membrane (ERM). Also, to investigate the effect of a dissociated optic nerve fiber layer (DONFL) appearance on RT. Methods: A non-randomized, retrospective chart review was performed for 159 patients who had successful closure of a MH, with (n = 148), or without (n = 11), ILM peeling. Also studied were 117 patients who had successful removal of an ERM, with (n = 104), or without (n = 13), ILM peeling. The RT of the nine Early Treatment Diabetic Retinopathy Study areas was measured by spectral domain optical coherence tomography (SD-OCT). In the MH-with- ILM peeling and ERM-with-ILM peeling groups, the RT of the operated eyes was compared to the corresponding areas of normal fellow eyes. The inner temporal/inner nasal ratio (TNR) was used to assess the effect of ILM peeling on RT. The effects of DONFL appearance on RT were evaluated in only the MH-with-ILM peeling group. Results: In the MH-with-ILM peeling group, the central, inner nasal, and outer nasal areas of the retina of operated eyes were significantly thicker than the corresponding areas of normal fellow eyes. In addition, the inner temporal, outer temporal, and inner superior retina was significantly thinner than in the corresponding areas of normal fellow eyes. Similar findings were observed regardless of the presence of a DONFL appearance. In the ERM-with-ILM peeling group, the retina of operated eyes was significantly thicker in all areas, except the inner and outer temporal areas. In the MH-with-ILM peeling group, the TNR was 0.86 in operated eyes, and 0.96 in fellow eyes (P <0.001). In the ERM-with-ILM peeling group, the TNR was 0.84 in operated eyes, and 0.95 in fellow eyes (P < 0.001). TNR in operated eyes of the MH-without-ILM peeling group was 0.98, which was significantly greater than that of the MH-with-ILM peeling group(P< 0.001). TNR in the operated eyes of the ERM-without-ILM peeling group was 0.98, which was significantly greater than that of ERM-with-ILM peeling group(P<0.001). Conclusion: The thinning of the temporal retina and thickening of the nasal retina after ILM peeling does not appear to be disease-specific. In addition, changes in RT after ILM peeling are not related to the presence of a DONFL appearance. © 2012 Kumagai et al, publisher and licensee Dove Medical Press Ltd.

Purpose. To determine the changes of regional macular thickness after successful macular hole surgery (MHS) with internal limiting membrane (ILM) peeling during a 24-month follow-up period. Methods. In a prospective, interventional case study, the authors evaluated 24 eyes of 24 patients who underwent 23-gauge transconjunctival pars plana vitrectomy with triamcinolone-assisted ILM peeling to treat idiopathic macular hole. Examinations were performed before and 1, 2, 3, 6, 9, 12, and 24 months after surgery. Average regional macular thicknesses in the Early Treatment Diabetic Retinopathy Study sectors were measured by spectral-domain optical coherence tomography. Results. The four inner sectors showed a significant reduction in the average retinal thickness at 1 month after surgery (P ≤ 0.0001-0.020), and the thickness continued to decrease for 24 months except in the nasal sector. The four outer sectors had a significant increase at postoperative 1 month (P = 0.0003-0.029) and then progressively decreased during the postoperative 24 months. The postoperative regional macular thinning was statistically significant even between 12 and 24 months (P = 0.0007-0.026) in all sectors except in the inner nasal sector (P = 0.13). The postoperative percent reduction rate was significantly different among four inner sectors after postoperative 3 months (P = 0.0029-0.039) in the order of temporal > superior > inferior > nasal sectors. Conclusions. These results suggest that a progressive macular thinning occurs for at least 2 years with different patterns of the changes in the macular regions after successful MHS with ILM peeling. © 2013 The Association for Research in Vision and Ophthalmology, Inc.

Purpose: To evaluate the effect of internal limiting membrane (ILM) peeling on the longterm visual outcomes in eyes with diffuse, nontractional diabetic macular edema. Methods: One hundred and sixteen eyes of 58 patients with the same degree of diabetic macular edema in both eyes underwent pars plana vitrectomy with the creation of a posterior vitreous detachment in both eyes. Internal limiting membrane peeling was performed in one randomly selected eye (ILM-off group), and ILM peeling was not performed (ILM-on group) in the fellow eye. The postoperative follow-up period ranged from 12 months to 161 months (average, 80.4 months). Results: In the ILM-off group, the mean best-corrected visual acuity in logMAR units (Snellen equivalent) increased from 0.55 ± 0.31 (20/71) before surgery to 0.35 ± 0.35 (20/45) at 1 year (P , 0.0001) and 0.46 ± 0.43 (20/59) at the final visit (P = 0.058). In the ILM-on group, the mean best-corrected visual acuity increased from 0.55 ± 0.41 (20/71) before surgery to 0.43 ± 0.38 (20/54) at 1 year (P = 0.010) and 0.44 ± 0.45 (20/56) at the final visit (P = 0.043). The differences in the best-corrected visual acuity between the two groups were not significant at any time point. Conclusion: Pars plana vitrectomy with or without ILM peeling improves the long-term visual acuity of nontractional diabetic macular edema. Internal limiting membrane peeling does not affect the postoperative best-corrected visual acuity significantly.

Purpose: To compare the vitreoretinal interface of the asymptomatic fellow eyes of patients with unilateral macular holes (MHs) with that of the asymptomatic fellow eyes of patients with other retinal diseases and with that of healthy eyes. Design: Retrospective, observational cross-sectional study. Participants: This study included 137 healthy volunteers and 929 eyes of 929 patients with various unilateral retinal diseases. Methods: We reviewed medical charts, fundus photographs, and spectral-domain optical coherence tomographic (SD OCT) images. The incidence of the features of the vitreoretinal interface and foveal structures in the SD OCT images were compared among the asymptomatic fellow eyes of patients with unilateral MHs (n = 242), age-related macular degeneration (n = 129), epiretinal membrane (n = 185), macular pseudohole (n = 48), rhegmatogenous retinal detachment (n = 68), retinal vein occlusion (n = 257), and 1 of the eyes of healthy individuals (n = 137). Main Outcome Measures: Findings of slit-lamp biomicroscopy and SD OCT B-scan images. Results: The SD OCT B-scan images showed different types of foveal deformations associated with vitreofoveal adhesions in eyes without a posterior vitreous detachment (PVD) in the macular area. The incidence of the foveal deformations associated with vitreofoveal adhesions was significantly higher (P<0.0001) in the fellow eyes of the unilateral MH group (17%) than that in the other groups (0%2%), except for the macular pseudohole group (8%). The SD OCT B-scan images also showed residual foveal deformations in eyes with a macular PVD. The incidence of a residual foveal deformation in eyes with a macular PVD was significantly higher (P<0.0001) in the MH group (32%) than that in any other group (0%-9%). Conclusions: The higher incidence of foveal deformations in the fellow eyes of patients with unilateral MHs with and without vitreofoveal adhesions suggests that patients in whom MHs develop have abnormally strong vitreofoveal adhesions sufficient to cause foveal deformation.

Purpose: To compare the morphologic parameters of ophthalmoscopically and tomographically normal foveae of the fellow eyes of patients with a unilateral macular hole (MH), other unilateral retinal diseases, and healthy eyes. Design: Observational, cross-sectional study. Methods: Of the 849 subjects studied, 183 eyes were excluded because they had an abnormal vitreofoveal interface that might have affected the foveal thickness. The average regional retinal thicknesses of the Early Treatment Diabetic Retinopathy Study sectors determined by spectral-domain optical coherence tomography were compared among 160 patients with MH, 175 patients with epiretinal membrane, 145 patients with retinal vein occlusion, and 186 healthy subjects. The foveal depression was quantified as the foveal pit depth divided by the foveal pit diameter. Results: The fovea (1 mm) and central fovea were significantly thinner in the MH group (243 and 192 μm) than in the other groups (P <.0001). There were no significant differences in the thickness of the fovea and central fovea among the eyes with epiretinal membrane (254 and 203 μm) or retinal vein occlusion (251 and 202 μm) or in the healthy group (254 and 201 μm). The foveal depression was significantly greater in the MH group (0.063) than in the retinal vein occlusion group (0.059) or in the healthy group (0.058; P =.014 and P =.0014, respectively). Multiple regression analyses showed that a thinner fovea and a deeper foveal depression were associated significantly with the presence of MH (P =.0054 to P <.0001). Conclusions: These results suggest that patients with MH have unique foveal morphologic features that predispose them to MH development. © 2013 by Elsevier Inc. All rights reserved.
