    CONCLUSIONS This trifocal IOL provided excellent visual outcomes at all distances with high spectacle independence and patient’s satisfaction.PURPOSE To examine the macular microstructure in macular edema (ME) due to retinal vein occlusion (RVO) in terms of ischemic or nonischemic type to determine whether and how ischemia affects macular microstructure. METHODS This retrospective, nonrandomized study included 75 newly diagnosed RVO cases (group 1 55 nonischemic RVO cases and group 2 20 ischemic RVO cases) with evidence of center-involving ME without any treatment. Quantitative measures on spectral-domain optical coherence tomography images were performed. Central subfield thickness (CST) was collected in the central 1 mm from the thickness map. The following items were evaluated in a 3-mm-wide area (perifoveal ETDRS circle) centered on the fovea disorganization of the retinal inner layers (DRIL), disrupted external limiting membrane (ELM) and ellipsoid zone disruption (EZD). The microstructural changes were measured manually. RESULTS Baseline characteristics, such as age, sex, study eye, and RVO risk factors, were similar between the groups (P > 0.05). CST was 554.15 ± 191.45 µm for group 1 and 769.90 ± 290.00 µm for group 2 (P 0.001). The extent of DRIL was 1864.09 ± 941.70 µm and 2447.25 ± 492.59 µm for groups 1 and 2, respectively (P 0.010). The disrupted ELM length was 1700 (0-3000) µm for group 1 and 2725 (300-3000) µm for group 2 (P 0.027). The EZD length was 1453.09 ± 870.38 µm for group 1 and 1846.00 ± 926.54 µm for group 2 (P 0.093). CONCLUSIONS Ischemic RVOs cause greater macular edema and greater disruption in the macular microstructure compared to nonischemic RVOs, especially in terms of DRIL and ELM.INTRODUCTION AND AIM To compare intraocular pressure (IOP) measurements obtained with non-contact tonometry (NCT), Icare rebound tonometry (IRT) and Goldmann applanation tonometry (GAT) in pediatric cases and to examine the effect of topical anesthesia on measurements obtained using IRT. MATERIALS AND METHODS Pediatric cases in a healthy general condition and with ophthalmic examination findings within normal limits were included in the study. IOP measurements were taken with NCT and IRT devices in all cases. Topical anesthesia was subsequently applied, and IOP measurements were then repeated using IRT and GAT tonometer devices. Differences between measurements were subjected to statistical analysis. RESULTS One hundred ten eyes of 55 patients, 27 male, with a mean age of 11.44 ± 2.31 years (7-17) were included. Mean pre-anesthesia IOP values were 16.47 ± 2.89 mmHg with NCT and 17.49 ± 2.57 mmHg with IRT. Mean IOP values after topical anesthesia were 16.91 ± 2.17 mmHg with IRT and 15.51 ± 2.41 mmHg with GAT. IOP measurement values obtained with all three devices exhibited positive correlation with central corneal thickness values. Statistically significant correlation was present in terms of IOP measurement values between all three devices. However, IOP values obtained with the three devices exhibited statistically significant differences. The application of topical anesthesia caused a statistically significant decrease in IRT measurements; however, statistically significant this small change (0.58 mmHg) in recorded IOP would not be considered clinically significant. CONCLUSION IOP measurements obtained with NCT, IRT and GAT devices in the pediatric age group correlate with one another, but differ from one another in a statistically significant manner. Application of topical anesthesia affects IRT measurements; however, these small changes would not be considered clinically significant.PURPOSE To establish the clinical features and outcomes of patients with chronically retained, feathery chestnut-burr spine-related corneal injury. METHODS The data of the patients who presented with chestnut-burr-related corneal injury between 2010 and 2018 were retrospectively evaluated. Nineteen eyes of 19 patients, with chronically retained corneal intrastromal feathery chestnut-burr spines, were included. RESULTS The mean age of the patients (11 male and 8 female) was 29.8 ± 19.9 years. Best-corrected visual acuity was 0.13 ± 0.23 logMAR at initial examination and increased to 0.0 ± 0.0 logMAR at last visit. Chestnut-burr spines were located in the peripheral cornea in 14 eyes (73.7%) and in the central cornea in 5 eyes (26.3%). Localized corneal edema surrounding the chestnut-burr spines were detected in all eyes. No eyes were Seidel positive. Three eyes (15.8%) had low-grade anterior chamber reaction. None of the patients had epithelial ulceration or any sign of infection at initial presentation. In order to control acute localized inflammation, all patients were put on topical steroid (loteprednol etabonate). The mean duration of topical steroid treatment was 3.8 ± 1.8 (range 2-7) months. During the follow-up period, inflammation was controlled and no sign of reinflammation occurred. CONCLUSION Acute inflammation in intrastromal chestnut-burr spines can be well controlled with easy tapering of topical steroids. However, as the reinflammation possibility cannot be excluded, long-term follow-up of these patients is mandatory.PURPOSE The aim of this study is to evaluate the retinal and choroidal structures in r- and nr-axSpA patients using spectral domain optical coherence tomography (SD-OCT) and to compare changes with healthy controls. METHODS In this cross-sectional study, 70 axSpA patients (50 radiographic- and 20 nr-axSpA) and 50 healthy control subjects were included. Choroidal thickness (ChT), macular thickness, retinal nerve fiber layer (RNFL), and the ganglion cell complex (GCC) were measured by SD-OCT. For ChT values, seven lines at nasal and temporal were drawn at 500-μm intervals, centering the subfoveal sclerochoroidal junction. Analysis of the data was performed with the SPSS program. Mann-Whitney U test was performed for comparison of non-normally distributed continuous data; Student’s t test was used for normal distributed data. RESULTS No significant difference was observed between 70 (66% male; mean age 39.7 ± 10.4 years) axSpA patients (50 radiographic and 20 nr-axSpA) and 50 (mean age 41.2 ± 6.2 years) healthy control subjects (p 0.417). R-axSpA and nr-axSpA groups and control group were similar in terms of spherical equivalent, intraocular pressure, axial length, and body mass index (p 0.574, p 0.874, p 0.918, p 0.344, respectively). While mean macular and GCC thicknesses were significantly lower in the patient group than in the healthy group, there was no significant difference between the two groups in terms of RNFL thickness. CONCLUSION The present study showed that there was no significant relationship between markers and scores indicating disease activity and ChT, MT, RNFL, and GCC thicknesses. However, an increase in choroidal thickness and involvement of the retinal layers has also been demonstrated in patients with spondyloarthritis. In addition, the relationship between disease activity and retinal layer involvement is remarkable in the r-axSpA group.PURPOSE To correlate the clinico-cytological features of dry eye among diabetic patients attending Lagos University Teaching Hospital, Lagos. METHODS This was a cross-sectional, comparative study among 104 diabetic and 104 age-/sex-matched non-diabetic participants. Demographics were obtained using interviewer-administered questionnaire. Ocular Surface Disease Index (OSDI) questionnaire was used for subjective assessment of dry eye. All participants underwent ocular examination and dry eye assessment including Schirmer I test, tear film break-up time (TBUT) and ocular surface staining. In addition, conjunctival impression cytology (CIC) samples were taken for histological assessment. Data were analysed using IBM Statistical Package for the Social Sciences version 20.0 (IBM Corp., Armonk, NY USA). RESULTS The mean age was 58.5 ± 10.05 years and 58.32 ± 10.48 years among the diabetics and non-diabetics, respectively (p = 0.856). The male/female ratio was 11.4. Three hundred and ninety-seven (199 diabetic and 198 non-diabetic) eyes were assessed. Diabetics had a significantly higher median OSDI score and ocular surface staining grade compared to non-diabetics (p = 0.002 and 0.005, respectively). The TBUT was slightly lower, while the Schirmer test was slightly higher among the diabetics, but not significant (p = 0.058 and 0.033, respectively). The diabetics had a significantly higher CIC grade (p  less then  0.001). There was a moderate positive correlation between conjunctival cytology and ocular surface staining (r = 0.50, p  less then  0.01). CONCLUSION This study demonstrates worse ocular surface damage among diabetics characterised by ocular surface staining and abnormal CIC. Furthermore, it shows a positive correlation between ocular surface staining and CIC. Dry eye assessment should be incorporated in routine diabetic eye screening.The corrected legend is given below.Many patients with traumatic brain injury (TBI) have persistent cognitive deficits, including decreased attention and working memory. This preliminary study examined fMRI data from a clinical trial implementing a 4-week virtual reality driving intervention to assess how sustained training can improve deficits related to traumatic brain injury. Previously-reported behavioral findings showed improvements in working memory and processing speed in those who received the intervention; this report explores the brain bases of these effects by comparing neural activity related to working memory (n-back task) and resting state connectivity before and after the intervention. In the baseline visit (n = 24), working memory activity was prominent in bilateral DLPFC and prefrontal cortex, anterior insula, medial superior frontal gyrus, left thalamus, bilateral supramarginal / angular gyrus, precuneus, and left posterior middle temporal gyrus. Following intervention, participants showed less global activation on the n-back task, with regions of activity only in the bilateral middle frontal cortex, posterior middle frontal gyrus, and supramarginal gyrus. Activity related to working memory load was reduced for the group that went through the intervention (n = 7) compared to the waitlist control group (n = 4). These results suggest that successful cognitive rehabilitation of working memory in TBI may be associated with increased efficiency of brain networks, evidenced by reduced activation of brain activity during cognitive processing. These results highlight the importance of examining brain activity related to cognitive rehabilitation of attention and working memory after brain injury.Attention-deficit/hyperactivity disorder (ADHD) is associated with increased risk of detrimental life outcomes. Recent research also indicates that ADHD is associated with sexual risk behavior, such as unprotected sex. Some risky sexual behaviors may be driven, in part, by preference for immediate rewards, referred to as delay discounting, which is prominent in etiological models of ADHD. Therefore, the present study examined the effect of delay on preference for both monetary and sexual outcomes in adults with many ADHD symptoms (both on and off medication) and with fewer ADHD symptoms. Online participants (N = 275; n = 161 males, n = 114 females) completed a monetary delay discounting task, assessing preference for smaller sooner versus larger delayed hypothetical money, and the Sexual Delay Discounting Task, assessing preference for condom use in hypothetical casual sex scenarios based on delay until condom availability. Those with greater ADHD symptoms discounted delayed monetary outcomes as well as delayed condom-protected sex (i.
