Introduction: Considering the increasing prevalence of myopia and the subsequent complications, and due to the dearth of studies on the correlation between myopia and gender with corneal thickness in Iran, this study aimed to determine this relationship in patients admitted to the ophthalmic clinic of Vali-e-Asr Hospital, Birjand, Iran. Methods: This descriptive-analytic epidemiologic study was conducted on 100 patients admitted to Vali-e-Asr ophthalmic clinic in Birjand, Iran, for one year since January 2017. According to the degree of myopia, the patients were divided into three groups of low (0-3 D), moderate (3-6 D), and high myopia (6≤D). Corneal thickness was measured using Orbscan and Pentacam. The data were analyzed in SPSS software (Version 19) through ANOVA and T-test to determine the possible relationship between myopia and central corneal thickness. A p-value equal to and less than (P≤0.05) was considered statistically significant. Results: Overall, 100 patients (49 males and 51 females) were enrolled in this study. Moderate myopia had the highest frequency in both eyes. The results of the T-test revealed that no significant difference was observed in the mean corneal thickness measured by Pentacam between the two genders (P=0.18 in the right eye and P=0.32 in the left eye). Based on the ANOVA findings, the mean corneal thickness measured by Pentacam was not significantly different among the myopia categories (P=0.05 in the right eye and P=0.51 in the left eye) Conclusions: The study results revealed that there was no significant relationship between myopia and gender with corneal thickness.

Background: Central Corneal Thickness (CCT) is an indicator of corneal health status as well as being an essential tool in assessment and management of corneal diseases. It is an important factor in the diagnosis and management of glaucoma as it affects the measurement of intraocular pressure. However, the pattern of central corneal thickness in our population is not known. Our study aimed to describe the CCT measurements and their variation with age and sex among patients attending the eye clinic at Muhimbili National Hospital (MNH), in Dar es Salaam, Tanzania. Methodology: A hospital-based descriptive, cross-sectional study used convenient sampling to recruit adult patients aged 18 years and above, presenting to the MNH between August 2016 and January 2017.Visual acuity assessment, Goldman applanation tonometry and CCT assessment using an ultrasound pachymeter were performed. Patients with previous intraocular surgery were excluded. Results: A total of 398 patients (208 males and 190 females) were recruited. The mean CCT was 526.64±38.30 µm; being 523.99±38.20 µm for males and 529.7±38.3 µm for females. 226 (56.85%) had CCT of less than 520 µm.There was no statistically significant difference in CCT between gender. The proportion of patients with thinner CCT increased with increasing age from 25.8% in those < 30 years to 75% in those aged 71years and above. The mean CCT decreased with increasing age with P-value<0.001. Conclusion: The average CCT in patients attending Muhimbili National Hospital is 526.64 µm (SD 38.30) which is generally thin, inversely proportion to age and similar that of other Africans and African-Americans. This finding has implications for the management of glaucoma in this population.

Aim: Foramen mentale is the anatomical formation in which the vein and nerve package feeds and provides sensory innervation to the chin and lower anterior lip area. During implant surgery and osteotomy operations, it is important to know the anatomical morphometric characteristics because of mental nerve damage. This study aims to determine whether mental foramen differ depending on age and gender. Method: 100 patients (50 females-50 males) who applied to neu faculty of dentistry and received kıbt for various reasons between 2020-2021 were included in the study. spss program was used for statistical analysis. a p value of <0.05 was considered significant. Results: The mean superoinferior diameter of the right and left mental foramen was 3.20 mm and 3.21 mm, respectively. The mean values were 3.12 mm and 3.18 mm for right and left mental foramen, respectively. It was found that the right and left mental foramen are located between the 1st and 2nd premolars. Anteroposterior and superoinferior diameters of the right and left foramen do not differ according to the localization of the mental foramen (p> 0.05). It was found that the parameters except the superoinferior diameter of the right mental foramen did not show a statistically significant difference according to gender (p> 0.05). It was found that the right mental foramen superoinferior diameter of males was statistically higher than females. (p <0.01). It was found that the anterosuperior and superoinferior diameters of the mental foramen did not vary according to age (p> 0.05). Conclusion: According to the result we obtained from this study, it was determined that the superoinferior diameter of the mental foramen was higher in men. This result will guide for those working in the field of anatomy, oral maxillofacial surgeons and oral maxillofacial radiologists.

Objectives: To compare central corneal thickness in myopic and keratoconuseyes by ultrasound pachymetry and pentacam HR. Study Design: Cross sectional study.Setting: Qassim University, Optometry Clinics, Kingdom of Saudi Arabia. Period: October2016 to April 2017. Methodology: One hundred myopic and keratoconus participants. CentralCorneal Thickness (CCT) were measured with two techniques by ultrasonic pachymetry andpentacam HR in two groups. Group one consisted of 80 myopic participants and group two of 20Keratoconuspatients.Pentacamreadings were recorded first. CCT were compared and analyzedstatistically using unpaired t-test and histogram. Results: One hundred participants (100) wereincluded in which 80 participants were myopic and 20 with keratoconus. Both eyes (200) of allthe participants were examined. Age of the myopics ranged from 18-30 years (Mean=23.03).The mean value with ultrasound pachymetery was 555μm (SD±32.021) and with pentacam566μm (SD±37.367). We observed a tendency of overestimation of CCT measurements withpentacam. Statistically a significant difference of reading between two devices (P<0.001) wasfound. In keratoconus participants, the mean age was 23.7 years (21- 26). The mean CCT takenwith Pentacam HR and US Pachymetry was 476μm (SD± 16.980) and 465μm (SD± 35.868)respectively. The t-test showed no statistical difference between thepentacam HR andultrasound pachymetry (p>0.214). Conclusion: Measurements of central corneal thicknessdone with Ultrasound Pachymeter and Pentacam HR are closely related to each other andare interchangeable when used in normal refractive error cases. While in Keratonus patientsultrasound pachymetry is preferred because of its reliability.

Abstract Background Chronic rhinosinusitis (CRS) is a common inflammation of the nose and the paranasal sinuses. Intractable CRS cases are generally treated with endoscopic sinus surgery (ESS). Although the effect of ESS on CRS symptoms has been studied, the pattern of symptom improvement after ESS for CRS is yet to be investigated. The aim of this study was to determine the magnitude and sequence of symptom improvement after ESS for CRS, and to assess the possible preoperative factors that predict surgical outcomes in CRS patients. Methods This was a longitudinal prospective study of 68 patients who had CRS (with or without nasal polyps). The patients underwent ESS at King Fahd Hospital of the University, Al Khobar, Saudi Arabia. The Sino-nasal Outcome Test-22 (SNOT-22) questionnaire was used for assessment at four time points during the study: pre-ESS, 1-week post-ESS, 4 weeks post-ESS, and 6 months post-ESS. Results The difference between the mean scores recorded for the five SNOT-22 domains pre-ESS and 6 months post-ESS were as follows: rhinologic symptoms (t-test = 7.22, p-value =  < 0.001); extra-nasal rhinologic symptoms (t-test = 4.87, p-value =  < 0.001); ear/facial symptoms (t-test = 6.34, p-value =  < 0.001); psychological dysfunction (t-test = 1.99, p-value = 0.049); and sleep dysfunction (t-test = 5.58, p-value =  < 0.001). There was a significant difference between the mean scores recorded for the five domains pre-ESS and 6 months post-ESS. Rhinologic symptoms had the largest effect size (d = 1.12), whereas psychological dysfunction had the least effect size (d = 0.24). The only statistically significant difference in the SNOT-22 mean scores recorded 4 weeks post-ESS was observed between allergic and non-allergic patients (t = − 2.16, df = 66, p = 0.035). Conclusion Understanding the pattern of symptom improvement following ESS for CRS will facilitate patient counselling and aid the optimization of the current treatment protocols to maximize surgical outcomes and quality of life. Level of evidence Prospective observational.

Purpose: To evaluate and compare corneal hysteresis (CH), corneal resistance factor (CRF), and central corneal thickness (CCT), measurements were taken between a healthy population (controls), patients diagnosed with glaucoma (DG), and glaucoma suspect patients due to ocular hypertension (OHT), family history of glaucoma (FHG), or glaucoma-like optic discs (GLD). Additionally, Goldmann-correlated intraocular pressure (IOPg) and corneal-compensated IOP (IOPcc) were compared between the different groups of patients. Methods: In this prospective analytical-observational study, a total of 1065 patients (one eye of each) were recruited to undergo Ocular Response Analyzer (ORA) testing, ultrasound pachymetry, and clinical examination. Corneal biomechanical parameters (CH, CRF), CCT, IOPg, and IOPcc were measured in the control group (n = 574) and the other groups: DG (n = 147), FHG (n = 78), GLD (n = 90), and OHT (n = 176). We performed a variance analysis (ANOVA) for all the dependent variables according to the different diagnostic categories with multiple comparisons to identify the differences between the diagnostic categories, deeming p < 0.05 as statistically significant. Results: The mean CH in the DG group (9.69 mmHg) was significantly lower compared to controls (10.75 mmHg; mean difference 1.05, p < 0.001), FHG (10.70 mmHg; mean difference 1.00, p < 0.05), GLD (10.63 mmHg; mean difference 0.93, p < 0.05) and OHT (10.54 mmHg; mean difference 0.84, p < 0.05). No glaucoma suspects (FHG, GLD, OHT groups) presented significant differences between themselves and the control group (p = 1.00). No statistically significant differences were found in the mean CRF between DG (11.18 mmHg) and the control group (10.75 mmHg; mean difference 0.42, p = 0.40). The FHG and OHT groups showed significantly higher mean CRF values (12.32 and 12.41 mmHg, respectively) than the DG group (11.18 mmHg), with mean differences of 1.13 (p < 0.05) and 1.22 (p < 0.001), respectively. No statistically significant differences were found in CCT in the analysis between DG (562 μ) and the other groups (control = 556 μ, FHG = 576 μ, GLD = 569 μ, OHT = 570 μ). The means of IOPg and IOPcc values were higher in the DG patient and suspect groups than in the control group, with statistically significant differences in all groups (p < 0.001). Conclusion: This study presents corneal biomechanical values (CH, CRF), CCT, IOPg, and IOPcc for diagnosed glaucoma patients, three suspected glaucoma groups, and a healthy population, using the ORA. Mean CH values were markedly lower in the DG group (diagnosed with glaucoma damage) compared to the other groups. No significant difference was found in CCT between the DG and control groups. Unexpectedly, CRF showed higher values in all groups than in the control group, but the difference was only statistically significant in the suspect groups (FHG, GLD, and OHT), not in the DG group.

SummaryAlthough factor V Leiden (FVL) is a major determinant of thrombotic risk, the reason why less than 10% of carriers eventually develop venous thromboembolic (VTE) events is unknown. Recent observations suggest that circulating levels of microparticles (MP) may contribute to the thrombogenic profile of FVL carriers. We measured the plasma level of annexin V-MP (AMP) platelet-MP (PMP), endothelial-MP (EMP), leukocyte-MP (LMP) and tissue factor-bearing MP (TF+MP), and the MP procoagulant activity (PPL) in 142 carriers of FVL (of these 30 homozygous and 49 with prior VTE), and in 142 age and gender-matched healthy individuals. The mean (± SD) level of AMP was 2,802 ± 853 MP/ μl in carriers and 1,682 ± 897 in controls (p<0.0001). A statistically significant difference between homozygous and heterozygous carriers of FVL was seen in the level of PMP, EMP and LMP, but not in that of the remaining parameters. When the analysis was confined to carriers with and without a VTE history, the mean level of AMP was 3,110 ± 791 MP/ μl in the former, and 2,615 ± 839 MP/μl in the latter (p<0.005). The mean level of all subtypes of circulating MP showed a similar pattern. The PPL clotting time was 39 ± 9 seconds (sec) in carriers, and 52 ± 15 sec in controls (p=0.003); and was 35 ± 8 sec in carriers with prior thrombosis, and 41 ± 10 sec in thrombosis-free carriers (p<0.005). Our study results suggest that circulating MP may contribute to the development of thrombosis in carriers of FVL mutation.

Purpose: Goldmann applanation tonometry (GAT) is considered the gold standard for Intraocular Pressure (IOP) measurement. It has the disadvantages of being a contact device, need for a slit-lamp, non-portability and need of a skilled examiner. Many hospitals are using a Non Contact Tonometry (NCT) as a screening device to save clinician time, however the usefulness is not proved in terms of reliability. This study was aimed to determine the usefulness of the Air-puff tonometer (TONOREF NIDEK II, NIDEK CO., LTD., JAPAN) over a GAT in a tertiary care center. Design: Cross-sectional Study Methods: This was a cross-sectional, non interventional observational study conducted on 224 eyes (right eye) from 224 patients. All patients underwent the IOP measurement with both methods and a central corneal thickness (CCT) measured. The data was analyzed using SPSS 20.0 software. Results: The mean age of the patients was 40.3±11.29 years. There was a statistically significant difference (p<0.001) between the mean NCT and GAT readings which persisted even after correction for central corneal thickness. The correlation between NCT and GAT using Pearson’s correlation coefficient was strong irrespective of the corrections for their corneal thickness (r = 0.751 and 0.718 for uncorrected and corrected values respectively). The correlation of the individual clinicians for the readings varied from moderate to strong. The ROC curve showed the best sensitivity and specificity to occur at around 13 to 14 mmHg. Conclusion: NCT seems to overestimate the IOP at low ranges as compared to the GAT and underestimate at higher ranges. The crossover of the values is seen between 12 to 13 mmHg.  The clinician should do an individualized analysis of his/her GAT measurements to the readings of the NCT machine at the clinic to obtain clinician specific nomogram.

Introduction: Good intensity of light dramatically affects the eyes. If there is less intensity of light. the eye muscles contract as much as possible to see objects or vice versa. If this happens continuously, it will cause damage to the eyes. Based on the preliminary study, it was found that as the auto welder operators have the task to observe the results of the auto welder engine to determine the quality of the welder, this type of work needs accuracy so that the right lighting intensity is required. This study aimed to determine the association between the lighting level and subjective visual fatigue complaints on operators in the auto welder section. Methods: The research method used was quantitative, with a cross- sectional approach and observational method. The samples in this study were 18 respondents from the total sampling technique. The instrument used was the Visual Fatigue Index (VTI) questionnaire. Moreover, the analysis of the study results used the one sample T-test statistical test to determine the association between the dependent and independent variables. Results: The one sample T-test results showed p-value = 0.012 < α = 0.05. This result showed an association between the lighting leveland subjective visual fatigue complaints on operators in the auto welder section. Conclusion: In this research, it was found that the majority of lighting levels that did not meet the standards had an association with subjective complaints of visual fatigue on the operators in the auto welder section.Keywords: auto welder, lighting, visual fatigue

Purpose. To study the variation of iris thicknesses in different regions and explore the possible correlations with age and gender. Methods. Healthy Chinese adults were recruited; the anterior segment of their eyes was imaged by swept-source optical coherence tomography (SS-OCT). The horizontal scan of the right eye was selected, and the thicknesses of both the nasal and temporal irises were measured at 199 evenly spaced points. Results. A total of 233 subjects with an average age of 36.79 ± 10.04 years (range 19 to 62) were included in the final analysis. The mean iris thicknesses of the temporal and nasal sides were 364.79 ± 47.58 μm and 372.44 ± 43.75 μm, respectively. The mean nasal iris thickness was positively correlated with age (β = 0.9 μm/year; P  = 0.002), but the temporal one was not (β = 0.077 μm/year; P  = 0.806). At 139 points of the nasal iris and 146 points of the temporal iris, the iris thickness was significantly correlated with age ( P  < 0.05). The thicknesses of the peripheral and pupillary parts were positively correlated with age, while the middle part was negatively correlated with age. No significant difference was observed in the mean iris thickness between genders (temporal: t = 1.597, P  = 0.112; nasal: t = 1.870, P  = 0.063), but females had a thicker iris than males at 50 points in the temporal side and 49 points in the nasal side ( P  < 0.05); no point in males was observed to have thicker iris compared to females. Conclusion. Using SS-OCT and the novel method, thicknesses of the iris at different regions were measured. The thicknesses of the peripheral and pupillary irises increase with age, while the thicknesses of the middle part decrease.
