<p><strong>Background:</strong> Intraocular pressure (IOP) is one of the most important parameters in the diagnosis and treatment of glaucoma. Glaucoma has been established as the second leading cause of blindness. The treatment of glaucoma focuses mainly on lowering intraocular pressure (IOP). The target IOP is often set to a level 20% to 30% of IOP reduction, and consequent large IOP reduction beyond 30% or even 40% in cases of advanced glaucoma The different methods of tonometery are: Goldman Applanation tonometery, Noncontact (air-puff) tonometery, Perkins tonometery, Tonopen tonometery, Transpalpebral tonometery.</p><p><strong>Objective:</strong> To determine the frequency of accuracy of intraocular pressure (IOP) measured by non-contact (air puff) tonometer compared with Goldmann applanation tonometer.</p><p><strong>Methods:</strong> This was a non-interventional, cross sectional study conducted at a tertiary care centre of Dhaka, Bangladesh. consecutive subjects attending the BSMMU eye OPD were included in the study. IOP was measured by non-contact (air puff) tonometer and a slit lamp mounted GAT in all the subjects. The study samples were selected by convenience sampling who presented for check-up in the Eye Department of community ophthalmology, Bangabandhu Sheikh Mujib Medical University, Dhaka. Bangladesh. Results:A total of 120 eyes in 60 patients were studied. The mean age of the patients was 41.60 year. study population consisted of 24 (40 %) men and 36 (60 %) women. The mean intraocular pressure was 13.52 &amp;13.72 mmHg for GAT, and 16.64 &amp; 17.44 mmHg for Air puff respectively. The range of measurements by GAT was from 10 to 23 mmHg and by Air puff was 12 to 28mmHg. The difference between IOP measured by two instruments were statistically significant (p=0.000).</p><p><strong>Conclusion:</strong> Airpuff tonometer is quick, a non-contact method to measure intraocular pressure and is useful for screening purposes and postoperative case but the measurements should be confirmed with Goldmann applanation tonometer for accurate labelling of intraocular pressure.</p>

Introduction: The exact position of the Parotid papilla and commissure of the lip plays a crucial role in determining the maxillary occlusal plane which directly facilitates rehabilitating edentulous patients with a removable complete denture. Since the beginning, many authors have conducted different studies regarding its position but multiple variations in its location have been noted. Also, this type of study has not been conducted in the Nepalese population which drags the urge to determine the position of these soft-tissue landmarks in context to the Nepalese population. Objective: To determine the position of parotid papilla and commissure of lip in relation to the maxillary occlusal plane. Materials and Methods: A descriptive cross-sectional study was conducted in the 45 dentate subjects visiting Nobel medical college from November 2019 to April 2020. A vestibular impression was made, stone index fabricated and vernier caliper was used to locate position of parotid papilla & commissure of lip. All the data were collected and statistically analyzed. Results: The mean measurement of distances between maxillary occlusal plane and parotid papilla was 3.69 ± 1.19 mm and between maxillary occlusal plane and commissure of lip was 0.41 ± 0.83 mm respectively. Conclusion: This study showed that the position of the parotid papilla was superior to the position of the maxillary occlusal plane with a mean distance of 3.69mm. The commissure of lip was found to be at the level of maxillary occlusion plane in highest number of cases followed by a superior position with least at the inferior position with respect to the maxillary occlusal plane.

PurposeTo validate estimation of Goldmann applanation tonometer (GAT) intraocular pressure (IOP) from scleral Schiotz IOP measurements using a regression model in normal eyes and eyes with type-1 keratoprostheses.MethodsIn this prospective cross-sectional study, cohort-1 had 253 normal anterior segment eyes, and cohort-2 had 100 eyes with type-1 keratoprostheses. Scleral Schiotz IOP measurements were used (in a non-linear model) to predict GAT IOP values for these eyes. Accuracy of predicted GAT IOP values was assessed using actual GAT IOP values for normal eyes, while for type-1 keratoprosthetic eyes, finger tension (FT) IOP assessments by an experienced glaucoma specialist were used. Primary outcome was agreement between FT IOP (assessed by an experienced glaucoma specialist) and predicted GAT IOP-derived clusters.ResultsThe actual values of GAT IOP measurements in normal eyes (n=253; mean age ±SD, 51.35±15.56 years) ranged between 6 mm Hg and 62 mm Hg (mean=22±10.05 mm Hg). Estimated and actual GAT IOP values for normal eyes were very similar (mean difference=0.05 mm Hg with limits of agreement: −5.39 to 5.5 by Bland-Altman plot). Of the 100 eyes with type-1 keratoprostheses, 68 were classified as having digitally normal IOP, 28 as borderline and 4 as high. The agreement between classification by FT assessment and model-predicted GAT IOP values was substantial (Kappa=0.81, 95% CI 0.69 to 0.93). The accuracy of the model in assessing IOP was found to be 91% (95% CI 0.84 to 0.96).ConclusionScleral Schiotz IOP values along with our predictive model can be an alternative objective method to FT IOP in assessing IOP in eyes with type-1 keratoprostheses.

Abstract Background Goldmann applanation tonometry (GAT) has been the gold standard for intraocular pressure(IOP) measurement ,since its appearance in clinical practice around 50 years ago.(1) In spite of being almost unchallenged, the last few years have become a sustained search for a new standard method for IOP measurement,. One such recently marketed instrument is the Ocular Response Analyzer (ORA), which able to detect the corneal biomechanics. Aim of the Work is to compare the IOP measurement estimated by Goldmann applanation tonometer to that of ORA and detect the effect of state of refraction, corneal topography and central corneal thickness (CCT) on these measurements. Patients and Methods This cross-sectional study was done from March 2018 to October 2018 on 65 eyes of patients visiting the outpatient clinic. Results The mean GAT IOP was 15.938 ± 6.041 while the mean ORA (IOPcc) and (IOPg) were 19.711 ± 7.59 and 17.242 ± 7.35 mm Hg respectively. There is a strong positive relationship between GAT IOP & ORA IOPg measurement (r = 0.880 – p = &lt;0.001*). Also finding a weak yet significant correlation between IOPg and CCT (r = 0.385, p = 0.001). None of the pressure measurements was affected by refraction or corneal curvature significantly. Conclusion In conclusion, our results suggest that mean IOPs obtained by ORA were significantly higher than that of GAT with different influencing factors that are not completely understood. caution has to be sought when using the ORA, the values obtained ought not to be used interchangeably with the values obtained by 1 GAT, despite the presence of a positive correlation between these values. This underlines the importance of using one and only method of evaluation of the IOP for every patient in successive follow-up visits.

Purpose. To compare a new digital Goldmann applanation tonometer (dGAT) that measures intraocular pressure (IOP) in 0.1 mmHg increments to a standard Goldmann applanation tonometer (sGAT).Methods. This study included 116 eyes of 60 subjects. A single examiner first measured IOP in triplicate using either sGAT or dGAT, which was randomly chosen. After a 5-minute interval, the next set of three consecutive IOP was measured using the other GAT.Results. The mean IOP measured with sGAT was 16.27 ± 6.68 mmHg and 16.35 ± 6.69 mmHg with dGAT. Pearson’s correlation coefficient was 0.998 (P<0.01). The subjects were divided into three groups based on the mean IOP: IOP < 14 mmHg, 14–20 mmHg, or >20 mmHg. The Pearson’s correlation coefficient within each group was 0.935, 0.972, and 0.997 (P<0.01), respectively. The difference within the three consecutive IOP measurements (maximum–minimum) for dGAT (0.72 ± 0.34 mmHg) was significantly smaller than those with sGAT (0.92 ± 0.42 mmHg,P<0.01). Even in patients with equal IOP (zero left-right difference) with sGAT (n=30), dGAT detected IOP differences between the left and right eyes (0.47 ± 0.31 mmHg).Conclusion. Compared to sGAT, dGAT measurements are highly reproducible and less variable.

Background: The covid pandemic started from Hubei, Wuhan in December 2020 then covered many other countries including India. Understanding the demographic and clinical characteristics of deceased COVID-19 patients could inform public health interventions focusing on preventing mortality due to COVID-19. The present study was done with the objective of studying the socio-demographic and clinical profile of deceased patients with coronavirus disease.Methods: This is a hospital based cross-sectional study on 1190 deceased patients of coronavirus disease in a tertiary care hospital of central India which is a dedicated covid hospital from 11 March 2020 to 28 February 2021. Socio-demographic and clinical characteristics of deceased patients were recorded.Results: Overall case fatality rate was 13.24%. Maximum number of deaths occurred in the month of August 2020 and September 2020 were 372 (31.26%) and 477 (40.08%). It was higher in the males 791 (66.47%) as compared to females 399 (33.53%), but the difference was not significant. The most common symptom was fever on hospitalization 924 (77.65%), followed by generalized weakness 771 (64.79%). 352 (29.58%) patients died within 24 hours of the admission to hospital. Hypertension and type 2 diabetes mellitus were the most prevalent morbidity in 557 (46.80%) and 357 (30.00%). It was found that 232 (19.50%) deceased patients had oxygen saturation less than 50% on admission.Conclusions: Higher age and presence of co-morbidities at the time of admission were significantly associated with mortality.

The purpose of this study was to compare the intraocular pressure (IOP) values measured with the Tono-Pachymeter NT530P (Tonopachy™) and the iCare® rebound tonometer (iCare®) with those obtained by the Goldmann applanation tonometer (GAT). The right eyes of 105 subjects aged 18 to 82 years (mean age = 29.27 ± 14.67 years) were assessed with the three tonometers. Central corneal thickness (CCT) was measured first using the Tonopachy™ and then IOP was measured by Tonopachy™, iCare® and GAT. The data was analyzed with descriptive statistics, paired  t-test, correlation and regression analysis. The Bland-Altman method of analysis was used to evaluate agreements between the sets of data from the three devices. The CCT values ranged from 440 µm to 606 µm (mean= 518.49 ± 33.01 µm). There was little or no correlation between CCT and IOP for any of the instruments used in this study (r = 0.29 for Tonopachy™, r = 0.22 for iCare®, r = 0.17 for GAT). The mean IOP measured with the Tonopachy™ was 14.31 ± 3.57 mmHg (range 8.7 mmHg to 31 mmHg) and 16.64 ± 4.38 mmHg (range 8 mmHg to 32 mmHg) using the iCare®. The mean IOP measured with the GAT was 14.79 ± 3.09 mmHg (range 8.7 mmHg to 29.7 mmHg). Using the Bland-Altman method, the upper and lower limits of agreement between the Tonopachy™ and GAT, iCare® and GAT, iCare® and Tonopachy™ were 5.1 mmHg and –4.2 mmHg, 8.6 mmHg and –4.9 mmHg, 7.5 mmHg and –2.8 mmHg respectively. In 79.1% of the eyes studied, the mean IOP difference between Tonopachy™ and GAT was less than 3 mmHg and in 20.9% of the eyes, the difference was greater than 3 mmHg. However, mean IOP differences of greater than 3 mmHg were obtained by iCare® in comparison with GAT (40%) and Tonopachy™ (34.3%) respectively. Findings of this study suggest that the Tonopachy™ yielded IOP readings that were consistent with those of GAT values while iCare® yielded higher IOP values compared to both GAT and Tonopachy™.

Introduction. Duodenal perforation is a common surgical emergency and carries mortality ranging from 4% to 30% reported in Western countries, but there is a paucity of reports from India. We aimed to determine the factors which influence the surgical outcomes in patients with duodenal perforation. Methods. We retrospectively analyzed prospectively collected data from January 2010 to December 2018. Results. A total of 55 patients were included in the study of which 69% (38) were males and 31% (17) were females (M : F = 4.5 : 2). The mean age was 52.3 years. The cause for duodenal perforation was duodenal ulcer (n = 25, 45.5%), followed by post-ERCP complications (n = 15, 27.3%), surgery (n = 11, 20%), and blunt trauma (n = 4, 7.2%) with perforations localized at D2 (n = 28, 51%) and at D1 (n = 27, 49%). Patients underwent primary repair with an additional diversion procedure (n = 28, 51%) and repair only in 18 (32.8%). There were 21 (38%) deaths. Patients with ERCP-associated duodenal perforation had longer hospital stay ( P ≤ 0.001 ), ICU stay ( P = 0.049 ), duration of drainage ( P ≤ 0.001 ), and higher leak rate ( P = 0.001 ) and re-exploration rate ( P = 0.037 ). A high mortality rate was seen in patients with preoperative organ failure (n  = 18, 78% versus 9.4%, P = 0.001 ), postoperative leak (n = 7, 64% versus 32%, P = 0.05 ), and longer duration from onset of symptoms to surgery (≥4 days) ( P = 0.045 ). Conclusion. Perforation of the duodenum is associated with high morbidity and mortality regardless of its cause and is higher in those who have a longer interval to surgery, preoperative organ failure, and a postoperative leak.

Purpose:  To compare the difference in intraocular pressure (IOP) measurements by Airpuff, iCare and Goldmann Applanation Tonometers (GAT). Study Design:  Comparative analytical study. Place and Duration of Study:  Department of Ophthalmology, Mohi-ud-Din Teaching Hospital, Mirpur Azad Kashmir, from June 2020 to August 2020. Methods:  Twenty-five patients (50 eyes) were included in this study. IOP was measured in each eye firstly by Airpuff tonometery, then by iCare tonometery and lastly by Goldmann applanation tonometer. Three consecutive readings were taken in each eye. If there was a difference of 2 mm Hg or more among the readings, measurement was repeated. Once we got three readings, their average was taken and analyzed. Comparison of IOP readings between these tonometers was done. Results:  Mean IOP was 15.84 ± 2.736 mm Hg with Airpuff Tonometer, 14.48 ± 2.435 mm Hg with iCare Tonopen and 14.74 ± 2.489 mm Hg with Goldman Applanation Tonometer. The difference between the mean Airpuff and Goldman Applanation Tonometer readings was 1.10 mm Hg which was not statistically significant (p-value = 0.083). The difference between the mean Goldman Applanation Tonometer and iCare Tonopen readings was 0.26 mm Hg which is also not statistically significant (p-value = 0.867). But, the difference between the mean iCare Tonopen and Airpuff Tonometer readings was -1.36 mm Hg which was statistically significant (p-value = 0.02). Conclusion:  It is concluded that IOP readings taken by iCare Tonopen and Airpuff Tonometer are comparable to those taken by Goldman Applanation Tonometer and iCare Tonopen underestimates the IOP when compared with Airpuff Tonometer. Key Words:  Airpuff Tonometer, Glaucoma, Goldmann Applanation Tonometer, iCare Tonometer, Intraocular Pressure.

Purpose: To compare the intraocular pressure (IOP) and central corneal thickness (CCT) of non-glaucomatous North-East (NE) Indian tribals and general Indians.  Materials and methods: In a prospective, cross-sectional study, the IOP and CCT of non-glaucomatous NE Indian tribals (n = 50) and non-glaucomatous general Indians (n = 50) were compared. Glaucoma was ruled out by history, detailed ocular examinations, and investigations. Results: There was very good correlation between the CCT and IOP values of right and left eyes (p = 0.940 and 0.847, respectively). The difference in the IOP values in the two groups was not statistically significant (p = 0.312 for Oculus Dexter [OD], p = 0.400 for Oculus Sinister [OS]). Similarly, the difference in the CCT values in the two groups was not statistically significant (p = 0.736 for OD and 0.613 for OS). The mean CCT and IOP OD for the whole population was 530.50 ± 35.42 μm and 13.80 ± 2.760 mmHg, respectively. By linear regression analysis, the IOP OD of the whole population had good correlation with CCT OD of the whole population (adjusted r2 = 0.084, p = 0.002), but not with age (adjusted r2=0.000, p=0.314) and sex (adjusted r2 = 0.010, p = 0.163). Similarly, CCT OD for the whole population did not have good correlation with age (adjusted r2 = -0.009, p = 0.762) and sex (adjusted r2 = -0.007, p = 0.603). Conclusions: In this study of individuals with normal corneas and without glaucoma, no racial variation was found in the CCT and IOP values of the two groups. The IOP OD of whole population had good correlation with CCT, but not with age and sex. There was good correlation between OD and OS values of IOP and CCT.
