ABSTRACT
Background : Lipid Peroxidation (LPO) plays a major initiative factor of cataractogenesis in both age-related or senile cataract and Diabetic cataract. Recently, 8-isoprostaglandin F2? (8-iso-PGF2?) is a reliable biomarker of in-vivo LPO and used as potential indicator of oxidative stress. However, serum 8-iso-PGF2? concentration and its association with glycemic control (HbA1c) in the pathogenesis of diabetic cataract subjects are still unknown. Objectives : The present study was designed to estimate 8-iso-PGF2? and antioxidant enzymes levels in serum of Type 2 Diabetes Mellitus patients with senile cataract compared to healthy individuals without cataract as control. To assess the magnitude of the association between 8-iso-PGF2? and glycemic status in diabetic cataract. Materials and Methods : 60 Diabetic Senile Cataracts (DSC) and 60 healthy individuals without cataract in the age group between 45-75 years of both genders. 8-iso-PGF2?, Superoxide Dismutase [Cu-Zn] (SOD3) and Catalase (CAT) concentration were estimated in serum by ELISA method. Results : The mean concentration of 8-iso-PGF2? was significantly increased (541.6±142.7 pg/ml, p<0.001) and mean concentration of SOD3 (102.1±32.8 ng/ml, p=0.007) and Catalase (1005±274.5 IU/ml, p<0.001) were significantly decreased in serum of diabetic senile cataract when compared to healthy individuals without cataract (control). A negative correlation between serum 8-iso-PGF2? and SOD3 and positive correlation between serum 8- iso-PGF2? and fasting blood glucose were observed in Diabetic Senile Cataracts. Conclusion : The present findings indicate that increased 8-iso-PGF2? is associated with oxidative stress which plays a significant role in the pathogenesis of cataract in diabetic patients

ABSTRACT
Background: The aim was to estimate the Serum Malondialdehyde (MDA) in the various morphological types and clinical stages of Age Related (Senile) Cataract, a common cause of curable blindness, especially in India.Methods: This was a study of estimation of serum Malondialdehyde (MDA) in 100 patients of Age Related (Senile) cataract with 80 cases of Senile Cortical type (40 cases of Posterior subcapsular and 40 cases of Mature) and 20 cases of Senile Nuclear type (10 cases of early Grades of I and II and 10 cases of Advanced Grades of III and IV) and in 20 cases of normal controls in the age group of 45 to 70 years.Results: Serum MDA (nmol/ml) values of the Mean with SD were 3.34±0.93 (Range 2.02-4.65) in normal controls, 4.38±1.01 (Range 2.4 - 6.7) in senile cataract, 4.39±1.02 ((Range 2.4-6.7) in Senile Cortical Cataract with 3.82±0.73 (Range 2.4-5.1) in its Posterior Subcapsular stage and 4.96 ± 0.88 (Range 3.3-6.7) in its mature stage and 4.3±0.99 (Range 2.4-6.2) in Senile Nuclear cataract with 3.68±0.66 (Range 2.4-4.7) in its early Grades of I and II and 4.86±0.94 (Range 3.8-6.2) in its Advanced Grades of III and IV.Conclusions: The present study showed a significant increased concentration of Serum MDA in Senile cataract especially in the advanced later clinical stages or grades of maturity than in the earlier clinical stages or grades of immaturity of senile cortical or nuclear compared to normal controls. And there was no statistically significant difference between the morphological types of Age related (Senile) cataract i.e. Cortical Cataract compared to Nuclear Cataract.
ABSTRACT
Background: The present study was aimed to study alterations in serum levels of calcium and phosphorus levels in senile cataract patients.Methods: 25 senile cataract patients in age group of 50 to 80 years and 25 control group were included in the study. Serum Calcium and Phosphorus levels were determined by Orthocresolphthalein, Fiske SubbaRow method respectivelyResults: Significantly increased levels of serum calcium in cataract patients (11.58�65 mg/dl) were found as compared to controls (8.53�45mg/dl) (p<0.0001). Serum phosphorus concentration in cataract patients (5.28�46 mg/dl) were significantly increased when compared to controls (3.02�23mg/dl) (p<0.0001).Conclusions: Presence of G-protein receptors in lens leads to the release of intracellular calcium. As total calcium in the lens increases, we hypothesize that higher intercellular calcium concentrations, coupled with decreased Ca2+-ATPase activity and greater membrane permeability could lead to elevated free intracellular calcium levels causing cataract. So, abnormal elevation of serum calcium and phosphorus can be used as a marker for prevention of age-related human cataract.
ABSTRACT
·AIM: To explore the effect of different incision phacoemulsification on corneal endothelial function and tear film function in senile cataract (SC) patients. ·METHODS: Totally 90 SC patients (90 eyes) admitted to our hospital were randomly divided into the 2. 2mm group ( n = 47, 47 eyes, 2. 2mm corneal micro - incision phacoemulsification) and the 3. 0mm group ( n= 43, 43 eyes, 3. 0 mm clear corneal micro - incision phacoemulsification). The indexes of corneal endothelial function and tear film function were compared between the two groups before and after operation. ·RESULTS: There was no statistical difference on the average phacoemulsification time (APT), mean effective phacoemulsification time( EPT ),average phacoemulsification energy ( AVE) and preoperative and postoperative intraocular pressure between the two groups (P>0. 05). There were statistical differences on the tear break-up time (BUT), basal tear secretion test (ST-Ⅱ), corneal sodium fluorescein staining (SCSF) score, corneal endothelial cell count, central corneal thickness and the variation coefficient of corneal endothelial cells between the two groups (P<0. 05). At 1wk and 1mo after operation, the BUT in the two groups was significantly lower than that before operation (P<0. 05) while the ST-Ⅱ was significantly higher than that before operation ( P< 0. 05), and the SCSF first increased and then decreased (P < 0. 05 ), and corneal endothelial cell count was significantly lower than that before operation (P<0. 05), and the central corneal thickness and the variation coefficient of corneal endothelial cells significantly increased (P<0. 05). The changed degrees of BUT, ST-Ⅱ, SCSF score, corneal endothelial cell count, central corneal thickness and corneal endothelial cell variation coefficient in the 2. 2mm group were less than those in the 3. 0mm group (P<0. 05). ·CONCLUSION: Phacoemulsification for SC patients can cause some damage in corneal endothelial function and tear film function, and 2. 2mm corneal micro-incision have less damage and faster early recovery.
ABSTRACT
AIM: To compare the difference in corneal endothelial cell density and morphology after phacoemulsification using Ringer lactate ( RL ) and balanced salt solution ( BSS) irrigating solutions.?METHODS: The prospective randomized controlled trial study was conducted between February 2017 and April 2017 in Dr. YAP Eye Hospital, Yogyakarta, Indonesia. There were a total of 52 subjects ( 52 eyes ) who were senile cataract patients further grouped into two, 26 patients undergoing the phacoemulsification procedure using RL irrigating solution and the other 26 patients with BSS irrigating solution, both conducted by one operator. On the 1, 7, and 28d post operative, an evaluation was done to measure the density and corneal endothelial cell morphology, as well as the variable of inflammation in the two groups.? RESULTS: Fifty - two eyes had undergone phacoemulsification with posterior intraocular lens implantation. Both groups were evaluated for the endothelial cell reduction and corneal endothelial cell morphology change, along with post - operative inflammation. On the 28d post-operative, endothelial cell reduction in the BSS group ( 173. 96 cell/mm2 , 8. 12％) was lower than the RL group (253.20 cell/mm2, 10.25％), percentage of corneal endothelial cell variation coefficient increase in the BSS group ( 2. 92％, 8. 36％) was lower compared to the RL group (3. 42％, 9. 96％), decrease of hexagonal cells of corneal endothelium cells presentation percentage in the BSS group (4. 30％, 8. 17％) was lower compared to the RL group (4. 84％, 8. 97％), and the percentage increase of central corneal thickness in the BSS group (4. 69 μm, 0. 89％) was almost equal to the RL group (4. 53 μm, 0. 90％). All of the results regarding difference in density and corneal cell endothelium morphology between the two groups did not reveal any statistically significant difference (P>0. 05). Inflammatory variable in the two groups were even.? CONCLUSION: BSS and RL were equal in their capability of maintaining endothelial cell loss and endothelial cell morphologic change in senile cataract patients after phacoemulsification.

ABSTRACT
·Cataract refers to the degenerative changes in lens quality caused by various causes of reduced transparency or color change. Surgical treatment is the main treatment modality at present. Among them, phacoemulsification has become the main surgical treatment for cataract because of its advantages such as short operation time, small incision and quicker healing. Today, cataract surgery has gradually shift to refractive surgery, and is no longer simply as cataract surgery. But after cataract phacoemulsification, the symptoms and visual quality are different. The main causes include refractive error, postoperative dry eyes and postoperative corneal astigmatism. This article reviews the factors that influence the visual quality of cataract phacoemulsification and its future trends.
ABSTRACT
Aim: The study was to analyze mean serum sodium and potassium levels in cataract patients and agematched individuals without cataract. Methods and Materials: It was a prospective case-control study. Individuals more than 50 years of age who attended our ophthalmic center in the year 2007-2010 were grouped into those having cataract and those without cataract. Mean serum sodium and potassium levels in the cataract groups were calculated and compared with the control group. Statistical software SPSS14 was used for statistical analysis. Results: Mean serum sodium levels in cataract group was 135.1 meqv/l and 133 meqv/l in the control group. Mean potassium was 3.96 meqv/l in the case study group and 3.97 meqv/l in controls. Mean sodium levels among cases were significantly higher than control group. No difference was seen in the PSC group and control. The difference in mean potassium among the two groups was statistically insignificant. Conclusion: Diets with high sodium contents are a risk factor for senile cataract formation and dietary modifications can possibly reduce the rate of progression cataract.
ABSTRACT
Abstract Introduction: During aging there is a close relationship between visual deficits, imbalance and falls, and eye surgery can be an efficient treatment option for elderly persons. Objective: Evaluate the influence of visual conditions on patients suffering from senile cataract with increasing imbalance. Method: A descriptive and analytical study using a quantitative longitudinal cohort technique was conducted. The study included 30 individuals who were evaluated before and 30 and 60 days after surgery. The Mini Mental State Examination (MMSE), Berg Balance Scale (BBS), Short Physical Performance Battery (SPPB), International Falls Efficacy Scale adapted for Brazil (FES-I) and a medical history questionnaire were used to collect data. Statistical analysis involved the Chi-squared, Student's t and Mann-Whitney tests. Values of p<0.05 were considered significant. Results: The SPPB found that of 15 elderly women, 13 (87%) achieved moderate performance of the lower limbs while the performance of two (13%) remained poor, after 60 postoperative days. The FES-I revealed that three (20%) elderly persons were mildly worried about falls 60 days post-surgery. Of the 15 elderly male subjects evaluated by BBS, before and at 30 and 60 days after surgery, one (7%), managed to maintain some balance but needed assistance; while 14 (93%) maintained good balance. The SPPB found that the performance of five elderly persons (33%) was moderate and that of nine (67%) was good. Conclusion: Senile cataract surgery had positive preventative effects on lower limb performance, balance and fear of falling among the elderly studied, preventing the falls and fractures that are common during aging.

ABSTRACT
Objective To explore the standard clinical pathway and stratified cost insurance in patients with senile cataract operation. Methods Patients treatment by senile cataract phacoemulsification combined with IOL implantation were selected as research subjects by cluster sample from two hospitals from 2013 to 2014 . Patients were divided into different groups according to the year, chronic diseases, preoperative waiting time. The difference of hospitalization expenses and hospitalization time were compared. Different levels of hospital costs were established by CHAID decision tree used hospitalization cost as target variable. Results The waiting time for operation was 2 days, the total hospitalized time was 5 days and these can be used as reference time in clinical pathway. Patients uninsured or with long waiting time for operation had longer hospitalized time. Chronic disease, terms of payment and waiting time before operation were point factors that effect the hierarchical of decision tree. Conclusion The new standard of clinical path need to adjust constantly. Distinguish different patients condition and pay different clinical path costs.
ABSTRACT
Cataract is the leading cause of low vision and blindness in the world. Most cataracts are related to aging because the life expectancy of population becomes increased in the world.However, the research ofthe types of cataracts has been studied in Mongolia, it is not investigating correlation between in the types of cataracts and the result of biochemistry, therefore it was the background of our research. To determine the correlation among the mongolians aged 50 and older for compare some biochemical results of blood and types of the senile cataract.Total 80 patients with cataract and aged over 50 were case-based selected for the study from November 2010 to November 2011 at the Department of Ophthalmology ofFirstCentral Hospital of Mongolia. There had been collected according to the questionnaire of risks, and records of biochemical examination. Eye examinations had been performed lenses evaluated with the biomicroscope and determined the lens opacities rightly to Lens Opacities Classification Systems-III (LOCS III, the international standard classification). And we used SPSS 16.0, The mean age of all participants was 70 (±9.36) years and 56.2% were female, 43.8% males. The study shows that cataract types: nuclear was 48.8%, cortical 10%, posterior subcapsular (PSC) 41.2%. The hypertriglyceridemia (≥2.26 mmol/L) was associated with PSC (p = 0.025). There was no statistically significant association between blood glucose and cholesterol level and senile cataract. Nuclear cataract was the most common type of senile cataracts in Mongolia. It was same that hypertriglyceridemia was related to PSC developing in comparison of some studies, which conducted in some nations.

ABSTRACT
Background: This study aims to assess the quality of life and the time trade off-utility value of the first eye cataract surgery and the second eye cataract surgery in Lombok Island-Indonesia. Methods: This was an epidemiologic survey study on community of cataract surgery. Evaluations of quality of life (QoL) and time trade-off (TTO) were performed using questionnaire prior and three weeks after cataract surgeries who had either first (group A) or second eye cataract surgery (group B). Personal data was noted especially on self-care, mobility, socially, and mentally status. Data was analyzed by chi-square test for categorical data and unpaired t-test or Mann-Whitney test for numeric data. Results: A total of 77 subjects was included in this study, there were 50 subjects in group A and 27 subjects in group B. Elements of QoL were improved after surgeries including self care, mobility, social, and mental status in both groups (p < 0.001). The modified TTO was accepted in 35 subjects in group A and 22 subjects in group B. Quality of life was improved in 46 patients in group A, there was further improvement in 22 patients in group B. The degree of patient’s expectation was good in 87% of all subjects. Conclusion: Second- eye cataract surgery showed further improvement in QoL despite better outcome of the first- eye cataract surgery. The outcome of cataract surgery conducted was relevant to the patient’s expectation.

El universo estuvo constituido por 800 ojos con diagnóstico de catarata senil. Se seleccionó una muestra de 200 ojos mediante muestreo aleatorio simple. En la recogida de los datos se expusieron todas las variables de interés de la investigación como edad y sexo, agudeza visual preoperatoria y posoperatoria, técnica anestésica empleada, percepción del dolor y complicaciones transoperatorias más frecuentes. Los datos fueron procesados y analizados mediante técnicas estadísticas descriptivas y porcentuales. Resultados: predominó el sexo femenino y el grupo de edad de 80 años o más. El mayor porcentaje de los pacientes refirió percepción leve del dolor con el uso de la anestesia epibulbar. Se observaron pocas complicaciones y una buena agudeza visual posquirúrgica. Conclusiones: la aplicación de la técnica de Blumenthal tiene buenos resultados en los pacientes operados de catarata senil
