RESUMEN

The aim of this study was to investigate whether inflammation mediates the previously observed direct association between the western dietary pattern (WDP) and metabolic syndrome (MetS) among Lebanese adults. Sociodemographic, lifestyle, dietary pattern scores, anthropometric and biochemical data of 331 adults were used in this study. Inflammation indicators considered were: serum C-reactive protein (CRP) and the dietary inflammatory index (DII). The scores of the WDP were significantly associated with DII (r = .64) but not with serum CRP. Higher CRP levels increased the odds of MetS and four out of five of its components, while no association was found between the DII and MetS. CONCLUSION: The findings of this study confirmed the association of serum CRP with MetS but did not support mediation effect of inflammation on the association between the WDP and MetS. These findings are important to direct future investigations on diet, inflammation and association with diseases risk.

RESUMEN

BACKGROUND: Proper nutrition is critical for healthy aging and maintaining functional independence. Limited research has been done on the assessment of dietary patterns of older adults and their association with diet quality indices. This study was conducted to identify, characterize, and evaluate the dietary patterns and diet quality of older adults in Lebanon, a middle-income country undergoing nutrition transition. METHODS: A cross-sectional population-based study was conducted on a nationally representative sample of community-dwelling older adults aged >50 years (n = 525). Socio-demographic, anthropometric, and lifestyle variables were collected through interviews, and dietary intake was assessed using a semi-quantitative food frequency questionnaire (FFQ). Five commonly used diet quality indices (DQIs) were calculated, including the Alternative Healthy Eating Index (AHEI), the alternate Mediterranean diet score (aMed), the Dietary Approach to Stop Hypertension (DASH) style diet score, and the Lebanese Mediterranean Diet index. Dietary patterns (DPs) were derived using exploratory factor analysis. Associations of identified DPs with energy, energy-adjusted nutrients, and DQIs were evaluated by Pearson's correlations. Multiple linear regression analyses were used to examine correlates of DPs. RESULTS: Three DPs were derived: Lebanese, Western, and High Protein/Alcohol patterns. The Lebanese pattern had highest correlations with fiber, folate, vitamin C, and all five DQIs. The Western was positively associated with energy and sodium and was inversely correlated with fiber, most vitamins, and a number of DQIs, namely AHEI, aMED, and DASH-style diet score. Highest correlations with intakes of proteins and fat were observed for the High Protein/Alcohol pattern. The Lebanese pattern was associated with female gender, education, nonsmoking and physical activity, whereas the Western pattern was associated with adverse health behaviors, including smoking, skipping breakfast, and physical inactivity. CONCLUSIONS: Of the three identified patterns, the Lebanese DP was associated with better diet quality and healthier lifestyle behaviors while the Western pattern implicated a lower quality diet. Public health programs promoting prudent diets, including the Mediterranean and Lebanese DPs, are needed to improve the diet quality of middle-aged and older adults in an attempt to improve their functionality and quality of life.

RESUMEN

Lebanon is currently experiencing unique and dynamic demographic shifts towards an aging population: past and present fertility are among the lowest in the Arab region and crude mortality rates have decreased in the past few decades from 9.1 to 7.1 per thousand. Increased waves of emigration of youthful adults seeking better work opportunities elsewhere, as well as counter-waves of 'return migration' of older Lebanese workers from neighboring host countries contribute further to the 'rectangularization' of the population pyramid. These trends are accompanied by an epidemiological transition towards non-communicable diseases, mental disorders and degenerative diseases as the leading causes of mortality and morbidity in lieu of communicable diseases. We examine in this paper the implications of these transformations on the health profile of older persons and on the social and health care available to them. Findings are discussed within the prevailing conflicts and political strife in the country, family transformations and structural settings including pension systems, health coverage, family support channels and social fabric, and nursing home-care. The paper ends with recommendations and options for.reforms.

RESUMEN

Older people constitute an overlooked vulnerable population in humanitarian crises. Lebanon is a small country that hosts the largest number of refugees per capita in the world. With exacerbating socioeconomic conditions, exclusionary policies against refugees, and a fragmented humanitarian system, the status of older Syrian refugees (OSRs) requires special attention. This study aimed to explore OSRs' unmet needs, coping strategies, available humanitarian services, and some indicators of the humanitarian inclusion standards focusing on the shelter, health, nutrition and food security, and water, sanitation and hygiene sectors. We conducted a convergent mixed-methods study between December 2021 and March 2022 in the North and Bekaa, including a cross-sectional survey with 461 participants and 14 semi-structured interviews. Results show that OSRs lived in inappropriate shelters (cold, leaking rainwater), especially in informal tented settlements. High rent prices pushed refugee households with elderly to prioritize paying rent at the expense of other needs such as food and medication, particularly when food cash transfer is the sole source of income, jeopardizing food security and intake. Access to dignifying and accessible bathing facilities was compromised in ITSs with shared facilities. Substantial medical costs hindered OSRs access to healthcare such as surgeries. Due to the crisis, chronic medications are not always available in dispensaries for subsidized cost, pushing OSRs to non-compliance and selling food assistance to buy medications. Soaring fuel prices hindered OSRs access to heating and transportation to receive healthcare. No efforts were reported in collecting data on OSRs' needs, targeting them with information on services, or soliciting feedback for programming, especially in the absence of any age-tailored interventions. Findings shed light on the precarious living conditions of OSRs in Lebanon and add to the body of evidence documenting their invisibility to the humanitarian response. An age-inclusive response is needed through holistic, tailored, and sustainable interventions.

RESUMEN

BACKGROUND: Older Syrian refugees in Lebanon are a marginalized population with under-recognized health needs. The inclusivity of this population within the humanitarian response is poorly understood. This study aims to identify the unique needs of older Syrian refugees in the context of recent concurrent crises in Lebanon, and explore the extent to which they are being met and prioritized by local and international aid agencies. METHODS: We conducted in-depth interviews with a snowball sample of 26 stakeholders from 11 organizations operating in the health, nutrition, and water, sanitation, and hygiene sectors. Data analysis followed principles of thematic analysis. RESULTS: Concurrent political, economic, and public health crises in host country promoted income insecurity among older refugees and increased dependency on younger relatives, leading to food insecurity, neglect, and poor health outcomes, including the sequelae of untreated non-communicable diseases. Mental illness was perceived to be exacerbated by Covid-19 related challenges, including social isolation, uncertainty about the future, and additionally due to feelings of guilt related to economic dependence and fundamental exclusion from labor force participation. Despite their vulnerability, older refugees are overlooked by the humanitarian response, which may be related to a lack of data. Pervasive medication shortages in the setting of the economic collapse, as well as inaccessible physical environments and competing interests were all identified as major barriers to care. CONCLUSIONS: Older Syrian refugees in Lebanon experience dual vulnerability that is acutely exacerbated in the setting of concurrent crises. Sociopolitical, economic, and cultural barriers promote social exclusion and may confer an increased risk of income and food insecurity in this population, with significant implications for health. Humanitarian aid agencies operating in the context of fragmented, under-resourced health systems are currently unable to sufficiently address multi-faceted needs of this community. We recommend moving away from a donor-dependent model of aid by allocating resources toward strengthening inclusive national health systems that emphasize preventative care. We further call for age-disaggregation of routine data and normalization of data sharing among stakeholders in the academic and public health sectors in order to develop evidence-based initiatives that can meet the needs of this under-served community.

RESUMEN

AIM: To examine the burden of cardiovascular disease (CVD) risk factors in Middle East and North Africa countries and their associations with dietary behaviors as nutrition transition is unfolding in the region. DATA: Data on CVD risk factors were collected from scholarly papers and a systematic review of published articles was performed. Dietary patterns were derived from the WHO Food and Agriculture Organization Statistical Databases. RESULTS: Wide variations exist across countries in the prevalence of CVD risk factors, namely obesity, diabetes, hypertension, hyperlipidemia, smoking and physical inactivity, with some countries showing high values of certain factors which approach those observed in the developed world. In particular, obesity prevalence rates have reached alarming levels, particularly among women in the oil-rich countries (over 40%), making it the most pressing health concern in the region. Trends in the dietary pattern illustrated a consistent rise in total energy supply by approximately 730 kcal per capita per day between 1970 and 2005. Dietary patterns showed an increased consumption of fat and animal protein and a decreased intake of carbohydrates, particularly whole grain cereals, and fresh fruits and vegetables. CONCLUSION: Regional differences were attributed to differences in lifestyle, occupation and a shift from traditional food habits. Our understanding of the CVD disparities across various geographic regions is key to our effort in planning relevant intervention programs. Public health efforts should focus on obesity, physical inactivity and unhealthy dietary practices. The success of these interventions depends on governmental commitment, multisectoral partnership and a consideration of the sociocultural norms of the target population.

RESUMEN

Bone mineral density (BMD) and fracture incidence vary greatly worldwide. The data, if any, on clinical and densitometric characteristics of patients with hip fractures from the Middle East are scarce. The objective of the study was to define risk estimates from clinical and densitometric variables and the impact of database selection on such estimates. Clinical and densitometric information were obtained in 60 hip fracture patients and 90 controls. Hip fracture subjects were 74 yr (9.4) old, were significantly taller, lighter, and more likely to be taking anxiolytics and sleeping pills than controls. National Health and Nutrition Examination Survey (NHANES) database selection resulted in a higher sensitivity and almost equal specificity in identifying patients with a hip fracture compared with the Lebanese database. The odds ratio (OR) and its confidence interval (CI) for hip fracture per standard deviation (SD) decrease in total hip BMD was 2.1 (1.45-3.05) with the NHANES database, and 2.11 (1.36-2.37) when adjusted for age and body mass index (BMI). Risk estimates were higher in male compared with female subjects. In Lebanese subjects, BMD- and BMI-derived hip fracture risk estimates are comparable to western standards. The study validates the universal use of the NHANES database, and the applicability of BMD- and BMI-derived risk fracture estimates in the World Health Organization (WHO) global fracture risk model, to the Lebanese.

RESUMEN

OBJECTIVE: To examine the differences between war and domestic ocular injuries during the Lebanese Civil War in terms of baseline characteristics, treatment provided and prognosis. METHODS: We retrospectively reviewed the charts of subjects with traumatic ocular injuries referred to a major medical center from 1980 to 1996. The variables were tabulated according to the international classification of ocular trauma. RESULTS: Compared to domestic ocular injuries, war injuries were significantly more likely to include males (84.7 vs. 75.1%) and adults (72.7 vs. 39.1%), concomitant systemic injury (43.7 vs. 10.1%), and bilateral ocular affection (19.3 vs. 4.4%). Also, patients with war injuries had significantly worse initial and final visual acuities, less visual improvement (28.6 vs. 44.8%), and more intraocular foreign bodies (42.9 vs. 11%), the majority being metallic removed via an electric magnet. Moreover, war injuries had significantly more posterior scleral involvement 5 mm behind the limbus (25.2 vs. 11.6%) with more secondary retinal detachment (10.3 vs. 4.8%) and vitreous hemorrhage (36.6 vs. 17.1%). Primary evisceration was performed significantly more frequently in war injuries (24.0%) than in domestic injuries (7.7%). CONCLUSIONS: During the Lebanese Civil War, war injuries compared to domestic ones were severer resulting in more enucleation/evisceration and more retinal detachment, tended to be bilateral, and were accompanied by concurrent systemic injuries and less visual recovery. Wearing special glasses and imposing an international arms embargo are recommended to decrease ocular injuries and blinding consequences in potential future wars.

RESUMEN

BACKGROUND: The literature remains controversial regarding seasonal variation of rhegmatogenous retinal detachment (RRD). METHODS: In this retrospective chart review, seasonal variation of RRD was examined based on the records of 211 consecutive patients operated for idiopathic RRD in one referral medical center over a 13-year period. RESULTS: The number of eyes with RRD recorded per season was 46 in autumn, 46 in winter, 62 in spring and 57 in summer. There was a significant seasonal variation (p < 0.05) with an increase in RRD in the warm seasons (spring and summer) compared to the cold seasons (winter and autumn; 56 vs. 44%). Right eyes were more likely to be affected than left eyes (54 vs. 46%), and cases presented with a significantly younger age at onset in the warm than in the cold seasons (47 vs. 54 years, p = 0.007). A literature review of 8,533 cases including the present case series established further the seasonal variation of RRD (p < 0.001). CONCLUSION: There is convincing evidence for a seasonal variation of RRD in Lebanon and in the literature. This is likely to be related to sun exposure and outdoor activities in the warm seasons.

RESUMEN

In many Middle Eastern countries including Lebanon, the family as a social institution is greatly valued and local norms regarding family ties and living arrangements are especially important for older adults, in particular older women. While the presence of an adult child is often seen as responsive to the financial, health and social needs of older parents, it is not clear whether co-residence with married children offers a similar advantage as in the case of co-residence with unmarried children. Using data from a national Population and Housing Survey, this study examines associations of co-residence with adult children among ever-married women aged 65 years and older in Lebanon. Results showed a considerable proportion of elderly women who were living alone (18%) at the time of the survey. Co-residence was more frequent with unmarried than married children, but the gender ratio of the co-residing child varied with the marital status of both the older woman and the child. Moreover, among those co-residing with married children, results indicate a greater likelihood of co-residence with married sons over married daughters. Co-residence with an adult child associated positively with the availability of surviving children and negatively with the socioeconomic status of the woman and her spouse. Compared to other living arrangements, co-residence with a married child entailed the least advantageous Household Socioeconomic Status (HSES) score in terms of housing characteristics, infrastructure, and material possessions, for both married and unmarried women.

RESUMEN

Background: Obesity is associated with increased risk for metabolic syndrome (MetS). Anthropometric cutoffs derived for Caucasians may not be applicable to identify obesity in Middle Eastern populations. This study aims to (1) determine optimal cutoff values of body mass index (BMI), waist circumference (WC), and waist-to-height ratio (WHtR) for the prediction of MetS among Lebanese adults and (2) to evaluate the ability of the derived cutoffs in predicting MetS, in comparison with published cutoffs. Methods: A cross-sectional study involving adults aged ≥20 years (n = 305) with no history of chronic diseases was conducted. Data collection included sociodemographic characteristics, anthropometric measurements, and fasting blood samples. The International Diabetes Federation criteria were used to identify MetS. Receiver operating characteristic analyses were performed to determine optimal cutoff values. The ability of the derived cutoffs in predicting MetS was examined using multiple logistic regression analyses. Results: The derived cutoff values for men and women were 26.35 and 25.74 kg/m2 for BMI, 94 and 83 cm for WC, and 0.54 and 0.53 for WHtR, respectively. The use of the derived cutoffs improved the prediction of MetS compared to reference published cutoffs. In men, abdominal adiposity indicators performed better than BMI in predicting MetS, while in women, BMI, WC, and WHtR were all strong predictors. Conclusion: The study identified, for three anthropometric indices, the optimal cutoff values that identify MetS among Lebanese adults, hence responding to the need for ethnic-and population-specific cutoffs. Of interest, the study results documented gender differences in the association between anthropometric indices and MetS.

RESUMEN

PURPOSE: To assess the role of bevacizumab in inflammatory ocular neovascularization. DESIGN: Retrospective, multicenter, consecutive case series of inflammatory ocular neovascularization. METHODS: Patients with inflammatory ocular neovascularization of varying causes for whom standard therapy failed were treated with intravitreal injection of bevacizumab. Main outcome measures included improvement of best-corrected visual acuity (BCVA) expressed in logarithm of minimum angle of resolution units, response of inflammatory ocular neovascularization by funduscopy and angiography, and decrease in central foveal thickness as measured by optical coherence tomography at the three-month follow-up. RESULTS: At the three-month follow-up, 84 eyes of 79 patients had been treated with a mean of 1.3 injections (range, one to three). Thirty-four eyes showed juxtafoveal choroidal neovascularization (CNV), 34 eyes showed subfoveal CNV, eight eyes showed peripapillary CNV, and 11 eyes showed neovascularization of the disc (NVD) or neovascularization elsewhere (NVE). BCVA improved 2.4 lines from 0.68 (6/28 or 20/94) to 0.44 (6/17 or 20/55) (P < .001). BCVA improved by one to three lines in 34.5% of the eyes, by four to six lines in 16.7% of the eyes, and by more than six lines in 14.2% of the eyes. Function was unchanged in 23.8% of the eyes. BCVA worsened in 10.7% (zero to three lines in 7.1%, more than four lines in 3.6%). Central foveal thickness decreased from baseline 346 to 252 microm (P < .001). For CNV, 32 eyes (43.2%) had complete regression after the injection, 27 (36.5%) had partial regression, five (6.8%) had no response, and 10 eyes (13.5%) were not evaluated by the contributors. For NVD or NVE, seven eyes (63.6%) had complete regression of new vessels and four eyes (36.4%) had partial regression after the injection. CONCLUSIONS: Intravitreal bevacizumab led to short-term significant visual improvement and regression of inflammatory ocular neovascularization in a wide variety of inflammatory ocular diseases.

RESUMEN

This study aimed to examine the proportion and socio-demographic correlates of Metabolically Healthy Overweight and Obesity (MHOv/O) among Lebanese adults and to investigate the independent effect of previously identified dietary patterns on odds of MHOv/O. Data were drawn from the National Nutrition and Non-Communicable Disease Risk Factor Survey (Lebanon 2008-2009). Out of the 337 adult participants who had complete socio-demographic, lifestyle, dietary as well as anthropometric and biochemical data, 196 had a BMI ≥ 25 kg/m² and their data were included in this study. MHOv/O was identified using the Adult Treatment Panel criteria. Dietary patterns previously derived in this study population were: Fast Food/Dessert, Traditional-Lebanese and High-Protein. The proportion of MHOv/O in the study sample was 37.2%. Females, higher education and high level of physical activity were positively associated with odds of MHOv/O. Subjects with higher adherence to the Traditional-Lebanese pattern had higher odds of MHOv/O (OR: 1.83, 95% CI: 1.09-3.91). No significant associations were observed between the Fast Food/Dessert and the high-protein patterns with MHOv/O. Follow-up studies are needed to confirm those findings and understand the mechanisms by which the Traditional-Lebanese pattern may exert a protective effect in this subgroup of overweight and obese adults.

RESUMEN

BACKGROUND: Coronary artery calcium score (CACS) correlates with atherosclerotic burden and predicts cardiac events. Most of the published data have been derived from the USA population. OBJECTIVE: To study the prevalence of coronary calcium in an asymptomatic population from the eastern Mediterranean region and compare it to data obtained from a large population study in the USA. RESULTS: A total of 1154 asymptomatic men and women from Lebanon underwent EBCT screening because of the presence of one or more CAD risk factors. Mean CACS as well as the percentile cut-points increased consistently with increasing age and, except for those above 74 years of age, were higher in men than women in each age stratum. Age, hypercholesterolemia, diabetes and smoking showed significant associations with CACS in men, while only age and hypercholesterolemia were significantly associated with CACS in women. Among men, the 75th and 90th percentile distributions were comparable to what is observed in developed countries such as the USA. CONCLUSION: Findings, from this first study in the region, suggest that despite a higher rate of diabetes and smokers in our study population, the CACS distribution in Lebanon is similar to that observed in the USA.

RESUMEN

Anticipating the direction of a confounding variable can be problematic especially to introductory students. Using elementary rules of mathematics, we describe below a simple instructional tool for deriving the direction of confounding bias. The tool is illustrated with examples and a heuristic mathematical justification is also described.

RESUMEN

BACKGROUND: Infections caused by extended-spectrum beta-lactamase (ESBL)-producing gram-negative bacilli constitute a growing problem worldwide. At the American University of Beirut Medical Center (AUBMC), we have observed a significant rise in the rates of ESBL-producing organisms over the past 5 years. METHODS: Using a case control study design, we compared 99 patients with infections caused by ESBL-producing Escherichia coli and Klebsiella species and 99 frequency-matched controls from which ESBL-nonproducing isolates were recovered at AUBMC. RESULTS: The most notable risk factor for acquiring infections with ESBL-producing organisms was antibiotic consumption within 30 days of the infection (OR, 7.06; 95% CI: 3.27-15.24), with third-generation cephalosporins being associated with the highest risk (OR, 28.4; 95% CI: 3.7-215.8). Other risk factors included recent surgery, presence of a urinary catheter, and need for mechanical ventilation. Moreover, cases had a longer mean duration of hospitalization and were more likely to have relapse of their infection than controls. CONCLUSIONS: Recent antibiotic use is by far the most important predisposing factor to infection with ESBL-producing organisms. Such infections are associated with prolonged hospital stay and increased morbidity. Attention should be redirected toward the unjustified liberal use of broad-spectrum antibiotics both in the hospital and in the community.

RESUMEN

OBJECTIVES: Assessing the prevalence of weight loss attempts in Beirut, Lebanon, a country characterized by a diversity of ethnic and religious groups and examining the interplay between ethnicity, body mass index (BMI) and weight perception and their relationship to weight loss behavior. METHODS: A school-based survey of risk behaviors conducted among secondary students (grade 10-12) in 1997. Subjects consisted of 827 boys and girls, aged 15 to 23 years, the majority of whom were Moslems (65.4%). Multiple logistic regression was used to estimate the association between ethnicity and weight perception with the likelihood of trying to lose weight controlling for BMI and a number of potential covariates. RESULTS: The prevalence of weight loss attempts was 19.1% and 42.6% in boys and girls respectively. Christians were more likely to perceive themselves as overweight and to attempt weight loss than Moslems across all BMI levels, however this trend was significant in the underweight category. While controlling for BMI did not change appreciably the results observed, after controlling for weight perception, ethnic differences in weight-loss behavior disappeared. CONCLUSION: Findings of the study suggest that whereas actual weight may constitute only partially the driving force for differentials by ethnicity, the perception of body weight acts as a mediating factor in the relationship between ethnicity and weight loss behavior. Understanding the disparities in weight management behavior across various adolescent groups is key to develop culturally appropriate educational and intervention programs for the youths.

RESUMEN

For the past two decades there has been a debate over the implementation of structural adjustment policies in the health sector of developing countries, much of it focusing on the political and economic relevance of the reform process for public health provision. However, very few studies have been able to assess the relevance of the private sector, which has had a central role in the restructuring of health services worldwide. Lebanon provides just such a case, with a predominantly private provider and the role of the state relegated to financing, with few controls over supply. This situation has ensured the systematic destruction of what remained of public provision in the 1970s. The country is now faced with one of the most expensive health services in the world, and one in which much of the population continues to live under conditions of considerable economic deprivation. The unique situation of Lebanon is maintained by its politics of confessionalism, with sociopolitical relations dominated by primordial ties of family, tribe, and kin, which does not seem to be an obstacle to the process of globalization. The authors suggest that this context reinforces the gross inequalities in access to health care; they explore the complex relationship between state, finance capital, and confessional politics in the context of health sector reform, in particular the financing of health care.

RESUMEN

OBJECTIVE: To examine the role of health conditions, socioeconomic, and socioenvironmental factors in explaining gender differences in physical disability among older adults. METHOD: We compared 412 women and 328 men residing in underprivileged communities in Lebanon on their activities of daily living (ADL), instrumental activities of daily living (IADL), and physical tasks (PT). Binary logistic regression analyses adjusting for possible explanatory covariates were conducted sequentially. RESULTS: Women showed higher prevalence rates of ADL, IADL, and PT compared to men. Gender disparities in ADL disability were explained by chronic-disease risk factors and health conditions (OR = 1.46; 95% CI = 0.94-2.25). The odds of disability in IADL and PT remained significantly higher for women compared to men after accounting for all available covariates. DISCUSSION: These results suggest underlying differences in functional status between women and men, yet, may have been influenced by the sensitivity of the measures to the social context and gendered environment surrounding daily activities.

RESUMEN

PURPOSE: We investigated the visual outcome of combined phacoemulsification with intravitreal bevacizumab, in eyes with dense cataract and visually significant exudative maculopathy. MATERIALS AND METHODS: Prospective longitudinal pilot study of consecutive patients treated by two surgeons in 2006, using intravitreal bevacizumab at the end of phacoemulsification. The historical control group consisted of consecutive subjects with exudative maculopathy and dense cataract treated by the same surgeons with the help of phacoemulsification without intravitreal bevacizumab prior to 2006. RESULTS: Thirty-one treated patients had the mean (SD) logMar best corrected visual acuity improving from - 1.48 (0.50) preoperatively to - 0.67 (0.38) in the first postoperative week (P < 0.001), to - 0.64 (0.40) in the first postoperative month (P < 0.001), and to - 0.62 (0.42) (P < 0.001) on the last follow-up (mean 4.2 months, range 1 - 9 months). Fourteen control patients had the mean (SD) logMar best corrected visual acuity improving from - 1.78 (0.79) preoperatively, to - 0.91 (0.53) in the first postoperative week (P < 0.001), to - 0.86 (0.45) in the first postoperative month (P < 0.001), and to - 0.90 (0.47) (P < 0.001) on the last follow- up (mean 19.6 months, range 1 - 49 months). Initial visual acuities, final visual acuities, and percentage of visual improvement at one month were all not significantly better in the intervention compared to the control group at one month. In the study group, the fovea was flattened at the one-month follow-up, by 90-diopter slit lamp examination and / or Optical coherence tomography. CONCLUSION: The combination of intravitreal bevacizumab and phacoemulsification is beneficial for maximal visual rehabilitation in the first postoperative month.
