To compare IOP measurement of Perkin’s tonometer and Schiotz tonometer with respect to Goldmann applanation tonometer (GAT).100 eyes of 50 patients aged 18 to 65 years presenting to Ophthalmology OPD were selected by randomization and detailed general and ophthalmic examination was done. IOP was measured using applanation tonometers (Perkin’s and GAT) and indentation tonometer (Schiotz tonometer) in that order. The study population included 38 male eyes and 62 female eyes; 50 right eyes and 50 left eyes. There was a statistically highly significant difference seen for the values between the groups (p<0.01) with higher values in IOP measured by GAT followed by IOP measured by Perkin’s tonometer and least in IOP measured by Schiotz tonometer.There was a statistically non significant difference seen for the values between Perkin’s tonometer and GAT (p>0.05). While there was a statistically highly significant difference seen for the values between GAT and Schiotz tonometer (p<0.01).There was a statistically non significant difference seen for the IOP values between right eye and left eye. There was a statistically non significant difference seen for the IOP values between males and females. Measurement of IOP with Perkin’s was closer to the values obtained by GAT. Perkin’s being portable, easy to use and precise tonometer than Schiotz tonometer, can be considered as an excellent substitute to GAT, for large scale examination, if cost is not a concern.

Purpose. To evaluate the different IOP readings by Goldmann applanation tonometer (GAT), ICare rebound tonometer, and Tono-Pen in keratoconus patients after MyoRing implantation. To assess the influence of central corneal thickness (CCT) and thinnest corneal location (TCL) on IOP measurements by different tonometers. Setting. Prospective observational study was conducted in two private centers in Egypt from February 2015 to November 2016. Methods. Seventeen eyes of 10 patients suffering from keratoconus and who underwent MyoRing implantation were recruited. All subjects underwent GAT, ICare, and Tono-Pen IOP measurements in random order. Central corneal thickness and thinnest corneal location were assessed by Pentacam. Difference in mean in IOP readings was assessed by T-test. Correlation between each pair of devices was evaluated by Pearson correlation coefficient. The Bland–Altman analysis was used to assess intertonometer agreement. Results. Seventeen eyes (10 patients) were evaluated. The mean IOP reading was 13.9 ± 3.68, 12.41 ± 2.87, and 14.29 ± 1.31 mmHg in GAT, ICare, and Tono-Pen group, respectively. There was a significant difference between IOP readings by GAT/ICare and Tono-Pen/ICare (p value: 0.032 and 0.002, respectively) with no significant difference between GAT/Tono-Pen (p value: 0.554). Mean difference in IOP measurements between GAT/ICare was 1.49 ± 2.61 mmHg, Tono-Pen/ICare was 1.89 ± 2.15 mmHg, and GAT/Tono-Pen was −0.39 ± 2.59 mmHg. There was no significant correlation between the difference in IOP readings among any pair of devices and CCC or TCL. The Bland–Altman analysis showed a reasonable agreement between any pair of tonometers.

Objective: To compare the intraocular pressure (IOP) values acquired from the non-contact tonometers and a Goldmann applanation tonometer in glaucoma patients. Materials and Methods: The present study included 300 eyes from 150 participants that attended the glaucoma outpatient clinic. The IOP was measured using both non-contact tonometry (NCT) and Goldmann applanation tonometry (GAT). The differences in IOP readings between the two techniques were evaluated. Results: The mean IOP as measured by NCT was 16.26±6.95 mmHg, when that of measured by GAT was 16.11±8.43 mmHg. The mean difference between the two techniques of measurement was 0.147±3.01 mmHg. The values acquired from NCT were slightly higher than those acquired by GAT in 49% of patients, and this difference was more distinct when the IOP as measured by GAT more than 21 mmHg. Conclusion: There was no statistically significant correlation in the measurement of IOP between non-contact and GAT tonometers. NCT is a proper method for mass screenings of IOP even if the IOP measurement by NCT is slightly higher than by GAT.

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 = <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.

Abstract Introduction A survey completed by junior doctors who routinely run eye casualty clinics identified Goldmann applanation tonometry (GAT) as the single most time-consuming element of a standard consultation. IOP can be measured with a range of devices in the eye clinic. By identifying the most accurate and time efficient method we can save time in consultations as well as provide better outcomes for the patient. Purpose To compare four tonometry techniques: Goldmann applanation tonometer(GAT), Non-contact tonometer(NCT), Tonopen(TP) and Icare tonometer(ICT) to determine the most accurate and efficient method. Method 20 subjects presenting in the casualty eye clinic were used in the study ranging between 36-75 years. Once undergoing routine ophthalmic examination from the same clinician, IOP was recorded with all devices. Three readings were taken before calculating an average value and time taken for each device for each patient. No patients were excluded from the study. Results The average IOP with GAT, NCT, TP and ICT was 8.5 ± 2.7, 10.3 ± 4.2, 8.6 ± 3.1, and 8.4 ± 4.5 mmHg, respectively. The average time taken with GAT, NCT, TP and ICT was 56, 132, 38 and 23 seconds, respectively. There was no significant difference in IOP measured by GAT and TP and ICT however, NCT (10.3 mm Hg, P < 0.01) measured significantly higher IOPs compared to GAT. Conclusion When compared to Goldmann applanation tonometer, Icare was the most accurate and efficient method. While Tonopen was fairly accurate some patients were unable to tolerate it. NCT was significantly slower compared to other devices.

Purpose To compare the IOP readings of an ocular blood flow (OBF) tonograph (OBF Labs UK Ltd) with Goldmann applanation tonometry. Methods 194 patients were studied. In group 1, the software version 8.2 of the OBF tonograph was used in 214 eyes of 107 patients and in group 2, the 11.2 version of the tonograph was used in 174 eyes of 87 patients. Results We found 63% of the OBF tonograph readings to be within ±2mm Hg of the Goldmann applanation tonometry readings in group 1 and 60% in group 2. In group 1 the correlation coefficient between the readings of the two instruments was 0.71 and 0.82 in group 2. The mean value for the paired differences in group 1 was –1.34±2.75mm Hg overall and –1.04±2.91mm Hg overall in group 2. There was a significant difference between the Goldmann applanation tonometer and OBF tonograph readings in the 8–10mm Hg interval (p<0.001) in group 1, but not in group 2 (p>0.1). Conclusions The 11.2 version of the OBF tonograph is more accurate than the 8.2 version and measures IOP in a manner that corresponds well to the Goldmann applanation tonometer in the 8–10mm Hg and 21–29mm Hg intervals. It corresponds fairly well in the 11–20mm Hg interval.

The study was carried out to evaluate the fate and outcome of eclampsia patients and their neonates. This hospital based prospective study was done in Chuadanga Sadar Hospital, a 100 bed secondary health care centre in Chuadanga district in Bangladesh, from January 2007 to December 2009. The number of study population was 50, which include antepartum, intrapartum and postpartum eclampsia. Among them, 70% had spontaneous vaginal delivery, 10% had assisted vaginal delivery and 10% had caesarian section. 86% of the patient have good maternal outcome with the use of anti convulsant therapy. 46% of baby of total population have good neonatal outcome with or without immediate resuscitation. The outcome of eclampsia is satisfactory if immediate treatment is started. Hence, every patient should be admitted in hospital as soon as possible and receive anticonvulsant therapy immediately, even before admission in hospital. Patient should be delivered with special care as a high risk mother and neonatal support should be given to reduce both maternal and neonatal mortality and morbidity.J Dhaka Medical College, Vol. 23, No.2, October, 2014, Page 223-226

Abstract Background Among different common types of cancer, gastric cancer (GC) is a worldwide health priority in both developing and developed countries. The aim of this study was to map the distribution of incident cases of GC in Iran to provide a geographical presentation of the incidence of the disease. Methods This study used the Iranian National Cancer Registry (INCR) data from 2004 to 2014. We calculated the crude and age-standardized incidence rates of GC for each province and also defined the frequency distribution of different types and locations of GC by the provinces. Results According to the results of the present study, the patients were predominantly male 49,907 (70.0%) and the most prevalent type of tumour was A1 (almost 96.4%) and C3‌ (2.0%). Also, a significant difference was observed between males and females in the distribution of the types of tumour (P < 0.001). In addition, a comparison of the distribution of the types of GC in Iran suggested that a significant difference exists between the provinces (P < 0.001). A significant difference was observed when the distribution of the location of GC tumors was compared between males and females and provinces (P < 0.001). Accordingly, pylori and cardia are the most common location of GC cancer among the study population (28.1% and 31.3% respectively). Conclusions The results of the current study suggested a higher rate of GC incidence in Iran when compared to the global figure in both females and males. Our study also revealed significant disparities between provinces with regard to the distribution of types, and location of GC. This may suggest involving different factors in GC in different parts of Iran. Further studies are needed to better understand the epidemiology and etiology of the disease in Iran.

Laparoscopic Hemicolectomy

Összefoglaló. Bevezetés: A laparoszkópia térhódítása a jobb oldali colon műtéteknél is nyilvánvaló. Ma legtöbb helyen a laparoszkóposan asszisztált jobb oldali hemikolektómia extrakorporális anasztomózissal a gold standard. A morbiditás randomizált vizsgálatok alapján még 30% körüli. A technikai fejlődés lehetővé tette az intrakorporális anasztomózist. Célkitűzés: Retrospektív módon elemezni rosszindulatú jobb oldali vastagbéldaganat miatt végzett laparoszkópos hemikolektómiák rövid távú eredményeit a két módszer összehasonlításával. Eredmények: 2018. 01. 01. – 2019. 12. 31. között 184 jobb oldali hemikolektómiát végeztünk, ezek közül 122 történt malignus betegség miatt. 51 esetben nyitott és 71 esetben laparoszkópos műtét történt. 37 férfi (átlagéletkor: 70,59 év) és 34 nő (átlagéletkor: 72,14 év) volt. 50 esetben extrakorporális (EA) és 21 esetben pedig intrakorporális anasztomózist (IA) végeztünk. Az EA csoportban 18, míg az IA csoportban 3 szövődmény alakult ki 30 napon belül (p = 0,067). Az EA csoportból 3, az IA csoportból 1 beteget veszítettünk el 30 napon belül (p = 0,66). Az átlagos ápolási idő az EA csoportban 9,48 (5–32) nap, míg az IA csoportban 6,52 (4–19) nap volt (p = 0,001) a szövődményes esetekkel együtt. A szövődményes esetek nélkül az EA csoportban 6,35 (5–10) nap, az IA csoportban pedig 5,55 (4–8) napnak bizonyult (p = 0,09). A műtéti idő pedig az EA csoportban 147 (90–240) perc, az IA csoportban pedig 146,47 (90–265) perc volt (p = 0,11). Konklúzió: Az irodalommal összhangban azt találtuk, hogy IA esetén kevesebb a szövődmény, ezzel is összefüggésben rövidebb az átlagos ápolási idő, és a műtéti időt tekintve nincs szignifikáns különbség. Ezeket figyelembe véve az intrakorporális anasztomózis javasolható jobb oldali laparoszkópos hemikolektómia esetén. Summary. Introduction: Laparoscopy became evident for right-sided colon surgery too. Today the laparoscopic-assisted right-hemicolectomy is the gold standard with extracorporeal anastomosis. Morbidity according to randomized trials is still approximately 30%. The development of the surgical technique resulted in the creation of intracorporeal anastomosis. Our aim was to compare the short-term results of the two methods. Aim: To analyse the short-term results of right-sided hemicolectomy that were performed due to malignant tumours with the comparison of the two methods. Results: A cohort of 184 right-sided hemicolectomy were performed from 01.01.2018 to 31.12.2019 from which 122 were operated on because of a malignant disease. 51 open and 71 laparoscopic operations were performed. The average age of 37 men and 34 women were 70.59 and 72.14 years, respectively. 50 patients underwent extracorporeal (EA) anastomosis and 21 intracorporeal (IA) anastomosis. Within 30 days the number of complications were 18 in the EA group and 3 in the IA group (p = 0.067). 3 from the EA group and 1 from IA group died within 30 days (p = 0.66). The average length of stay were 9.48 days in the EA group and 6.52 days in the IA group together with the complicated cases (p = 0.001) while 6.35 days and 5.55 days without the complicated cases (p = 0.09). The average duration of operation was 147 minutes in the EA and 146.47 minutes in the IA group (p = 0.11). Conclusion: We found concordance with the literature that there are fewer complications in case of IA which might be related to shorter length of stay. There is no significant difference between the surgical times. Bearing these facts in mind, IA might be suggested for right- sided laparoscopic hemicolectomy.
