Driving performance of long-term users of sedating antidepressants and benzodiazepines.

OBJECTIVE: Using benzodiazepines and certain antidepressants is associated with an increased risk of motor vehicle crashes due to impaired driving skills. Hence, several countries prohibit people who use these drugs from driving. Traffic regulations for driving under the influence of these drugs are, however, largely based on single-dose studies with healthy participants. The effects of drugs on chronic users may be different because of potential development of tolerance or by adapting behavior. In this study, we test the effects of anti-depressants, hypnotics, or anxiolytics use on driving performance in patients who use these drugs for different durations and compare the effects to healthy controls' performance. METHODS: Sixty-six healthy controls and 82 medication users were recruited to perform four drives in a driving simulator. Patients were divided into groups that used anti-depressants, hypnotics, or anxiolytics, for shorter or longer than 3 years (i.e. LT3- or LT3+, respectively). The minimum term of use was 6 months. Driving behavior was measured in terms of longitudinal and lateral control (speed variability and Standard Deviation of Lateral Position: SDLP), brake reaction time, and time headway. Impaired driving performance was defined as performing similar to driving with a Blood Alcohol Concentration of 0.5‰ or higher, determined by means of non-inferiority analyses. RESULTS: Reaction time analyses revealed inconclusive findings in all groups. No significant performance differences between matched healthy controls, LT3- (n = 2), and LT3+ (n = 8) anxiolytics users were found. LT3+ antidepressants users (n = 12) did not perform inferior to their matched controls in terms of SDLP. LT3- hypnotics users (n = 6) showed more speed variability than their matched healthy controls, while this effect was not found for the LT3+ group (n = 14): the latter did not perform inferior to the healthy controls. Regarding Time Headway, no conclusions about the LT3- hypnotics group could be drawn, while the LT3+ group did not perform inferior compared to the control group. CONCLUSIONS: The small number of anxiolytics users prohibits drawing conclusions about clinical relevance. Although many outcomes were inconclusive, there is evidence that some elements of complex driving performance may not be impaired (anymore) after using antidepressants or hypnotics longer than 3 years.

[Involving forensic psychiatric patients in scientific research]. / De bereidheid van forensisch psychia­trische patiënten tot deelname aan wetenschappelijk onderzoek.

Background Forensic psychiatric patients are at risk to cause damage to society in the future again, both materially and immaterially. Little is known about the pharmacotherapeutic or psychotherapeutic treatment of the specific psychopathology of forensic psychiatric patients. This is possibly due to scarcity of research in the field, which could be caused by the fact that forensic psychiatric patients are often unwilling to participate in scientific research. Aim To explore the reasons why patients are unwilling to participate in research. Method Sixty-five forensic psychiatric patients were asked about their opinion on participating in pharmacological, psychotherapy, MRI- and DNA research.  Results The main reasons for not participating in pharmacological research were 'patient's belief that they will not benefit from participation in research' and 'physical integrity' (the fear of being physically harmed by participation in research). 'General resistance' (not willing to take part for no particular reason) was the main reason for not participating in psychotherapy-, MRI and DNA research.  Conclusion In order to enhance willingness to take part in research, informing the patients in the right manner with the aim of taking distrust away, would be important. Also, it could be helpful to offer a reward for participation in scientific research, although this could lead to ethical complications.

Breaking the trade-off between fast control and long lifetime of a superconducting qubit.

The rapid development in designs and fabrication techniques of superconducting qubits has made coherence times of qubits longer. In the future, however, the radiative decay of a qubit into its control line will be a fundamental limitation, imposing a trade-off between fast control and long lifetime of the qubit. Here, we break this trade-off by strongly coupling another superconducting qubit along the control line. This second qubit, which we call "Josephson quantum filter" (JQF), prevents the first qubit from emitting microwave photons and thus suppresses its relaxation, while transmitting large-amplitude control microwave pulses due to the saturation of the quantum filter, enabling fast qubit control. This device functions as an automatic decoupler between a qubit and its control line and could help in the realization of a large-scale superconducting quantum processor by reducing the heating of the qubit environment and the crosstalk between qubits.

Development and field testing of low-cost, quantal microbial assays with volunteer reporting as scalable means of drinking water safety estimation.

AIMS: To evaluate a low-cost water quality test for at-scale drinking water safety estimation in rural India. METHODS AND RESULTS: Within a longitudinal study to characterize variability in household drinking water safety in rural Maharashtra, we piloted a low-cost presence-absence (LCPA) microbial test designed to be used by volunteer residents in rural areas. In comparing the LCPA results with standard laboratory methods for enumeration of Escherichia coli, we found that LCPA tests using modified mTec media were highly sensitive in detecting drinking water of moderate risk (88% of tests were positive at E. coli counts of 11-100 CFU per 100 ml) and high risk (96% of tests were positive at E. coli counts of 101 + CFU per 100 ml). The LCPA tests demonstrated low specificity for E. coli specifically, due to concurrent detection of Klebsiella: 38% of LCPA tests were positive even when E. coli was not detected in a 100 ml sample by membrane filtration, suggesting the test would be conservative in risk estimation. We also found that 47% of participants in rural villages in India were willing to conduct tests and return results after a brief training, with 45% of active participants sending their water testing results via short message service. CONCLUSIONS: Given their low cost (~US$0.50 as piloted) and open-source format, such tests may provide a compelling alternative to standard methods for rapid water quality assessments, especially in resource-limited settings. SIGNIFICANCE AND IMPACT OF THE STUDY: The lack of availability of water quality data constrains efforts to monitor, evaluate and improve the safety of water and sanitation infrastructure in underserved settings. Current water testing methods are not scalable because of laboratory and cost constraints. Our findings indicate the LCPA or similar low-cost microbial tests could be useful in rapid water safety estimation, including via crowdsourcing.

Alcohol metabolism in hangover sensitive versus hangover resistant social drinkers.

BACKGROUND: Previous research demonstrated that urinary ethanol concentrations were significantly lower in hangover resistant individuals compared to drinkers who reported having a hangover. This finding suggests that the rate of ethanol metabolism is faster in drinkers who do not experience an alcohol hangover. This study aimed to directly compare alcohol metabolism after administering a low dose of ethanol to hangover sensitive drinkers and hangover resistant drinkers. METHODS: Social drinkers who previously participated in hangover trials at Utrecht University were invited to participate. It was aimed to include 12 hangover resistant drinkers and 12 hangover sensitive drinkers. Participants consumed alcohol to reach a breath alcohol concentration (BrAC) of 0.05%. Every 5 min BrAC was determined, until BrAC reached zero. Every 15 min, the Karolinska Sleeping Scale (KSS) was administered to assess subjective sleepiness, and subjective intoxication was measured. RESULTS: Data of N = 23 participants with a mean age of 22.4 (±1.9) years was included in the analyses. No significant difference in BrAC over time was found between the hangover resistant group and the hangover sensitive group. In line, subjective sleepiness scores and subjective intoxication ratings did not significantly differ between the groups at any point in time after alcohol consumption. CONCLUSION: Hangover resistant individuals and hangover sensitive drinkers did not significantly differ on BrAC, subjective sleepiness, and subjective intoxication after consuming a moderate amount of alcohol. These findings suggest that drinkers who usually experience hangovers after a heavy drinking occasion do not experience alcohol intoxication differently than hangover resistant drinkers.

Strong coupling of magnons in a YIG sphere to photons in a planar superconducting resonator in the quantum limit.

We report measurements made at millikelvin temperatures of a superconducting coplanar waveguide resonator (CPWR) coupled to a sphere of yttrium-iron garnet. Systems hybridising collective spin excitations with microwave photons have recently attracted interest for their potential quantum information applications. In this experiment the non-uniform microwave field of the CPWR allows coupling to be achieved to many different magnon modes in the sphere. Calculations of the relative coupling strength of different mode families in the sphere to the CPWR are used to successfully identify the magnon modes and their frequencies. The measurements are extended to the quantum limit by reducing the drive power until, on average, less than one photon is present in the CPWR. Investigating the time-dependent response of the system to square pulses, oscillations in the output signal at the mode splitting frequency are observed. These results demonstrate the feasibility of future experiments combining magnonic elements with planar superconducting quantum devices.

Urine methanol concentration and alcohol hangover severity.

BACKGROUND: Congeners are substances, other than ethanol, that are produced during fermentation. Previous research found that the consumption of congener-rich drinks contributes to the severity of alcohol hangover. Methanol is such a congener that has been related to alcohol hangover. Therefore, the aim of this study was to examine the relationship between urine methanol concentration and alcohol hangover severity. METHODS: N = 36 healthy social drinkers (22 females, 14 males), aged 18-30 years old, participated in a naturalistic study, comprising a hangover day and a control day (no alcohol consumed the previous day). N = 18 of them had regular hangovers (the hangover group), while the other N = 18 claimed to be hangover-immune (hangover-immune group). Overall hangover severity was assessed, and that of 23 individual hangover symptoms. Urine methanol concentrations on the hangover and control days were compared, and correlated to hangover (symptom) severity. RESULTS: Urine methanol concentration was significantly higher on hangover days compared to control days (p = 0.0001). No significant differences in urine methanol concentration were found between the hangover group and hangover-immune group. However, urine methanol concentration did not significantly correlate with overall hangover severity (r = -0.011, p = 0.948), nor with any of the individual hangover symptoms. These findings were observed also when analyzing the data separately for the hangover-immune group. In the hangover group, a significant correlation with urine methanol concentration was found only with vomiting (r = 0.489, p = 0.037). CONCLUSION: No significant correlation was observed between urine methanol concentration and hangover severity, nor with individual core hangover symptoms.

Combination Regimens for Treatment of Carbapenem-Resistant Klebsiella pneumoniae Bloodstream Infections.

Previous studies reported decreased mortality in patients with carbapenemase-producing Klebsiella pneumoniae bloodstream infections (BSIs) treated with combination therapy but included carbapenem-susceptible and -intermediate isolates, as per revised CLSI breakpoints. Here, we assessed outcomes in patients with BSIs caused by phenotypically carbapenem-resistant K. pneumoniae (CRKP) according to the number of in vitro active agents received and whether an extended-spectrum beta-lactam (BL) antibiotic, including meropenem, or an extended-spectrum cephalosporin was administered. We retrospectively reviewed CRKP BSIs at two New York City hospitals from 2006 to 2013, where all isolates had meropenem or imipenem MICs of ≥4 µg/ml. Univariate and multivariable models were created to identify factors associated with mortality. Of 141 CRKP BSI episodes, 23% were treated with a single active agent (SAA), 26% were treated with an SAA plus BL, 28% were treated with multiple active agents (MAA), and 23% were treated with MAA plus BL. Ninety percent of isolates had meropenem MICs of ≥16 µg/ml. Thirty-day mortality was 33% overall and did not significantly differ across the four treatment groups in a multivariable model (P = 0.4); mortality was significantly associated with a Pitt bacteremia score of ≥4 (odds ratio [OR], 7.7; 95% confidence interval [CI], 3.2 to 18.1; P = 0.1), and immunosuppression was protective (OR, 0.4; 95% CI, 0.2 to 1.0; P = 0.04). Individual treatment characteristics were also not significantly associated with outcome, including use of SAAs versus MAA (26% versus 38%, P = 0.1) or BL versus no BL (26% versus 39%, P = 0.1). In summary, in patients with CRKP BSIs caused by isolates with high carbapenem MICs, the role of combination therapy remains unclear, highlighting the need for prospective studies to identify optimal treatment regimens.

Ocular manifestations of dengue fever in University Malaya Medical Centre.

This time-framed study describes the spectrum of ocular manifestations in patients with dengue fever and the association between maculopathy with the stages of dengue fever. This cross sectional prospective study involved 145 dengue inpatients recruited from University Malaya Medical Centre. Observed parameters were stages of dengue infection, abnormal fundus and types of maculopathy. Retinal abnormalities involved the peripheral region in 3 patients (1.03%) and the macula in 13 patients (4.48%). The types of maculopathy encountered were macular oedema 7 (53.8%), cystic appearance 4 (30.8%), macular haemorrhage 1 (7.7%) and yellow spots 1(7.7%). Reduced distance VA, visual scotoma and metamorphopsia and abnormal Amsler grid test correlated with maculopathy, p< 0.05. Maculopathy correlated well with dengue with severe leakage (p= 0.025). Our study found the prevalence of maculopathy in dengue infection to be 4.48% in UMMC. The significant predictors of maculopathy were dengue with severe leakage, visual scotoma, metamorphopsia, distance VA impairment and abnormal Amsler grid test. This study was funded by a University Malaya Grant - URMG no: RP006D-13HTM.

The effect of a forced-air warming blanket on patients' end-tidal and transcutaneous carbon dioxide partial pressures during eye surgery under local anaesthesia: a single-blind, randomised controlled trial.

Surgical drapes used during eye surgery are impermeable to air and hence risk trapping air underneath them. We investigated the effect of a forced-air warming blanket on carbon dioxide accumulation under the drapes in patients undergoing eye surgery under local anaesthesia without sedation. Forty patients of ASA physical status 1 and 2 were randomly assigned to either the forced-air warmer (n = 20) or a control heated overblanket (n = 20). All patients were given 1 l.min(-1) oxygen. We measured transcutaneous and end-tidal carbon dioxide partial pressures, heart rate, arterial pressure, respiratory rate, temperature and oxygen saturation before and after draping, then every 5 min thereafter for 30 min. The mean (SD) transcutaneous carbon dioxide partial pressure in the forced-air warming group stayed constant after draping at 5.7 (0.2) kPa but rose to a maximum of 6.4 (0.4) kPa in the heated overblanket group (p = 0.0001 for the difference at time points 15 min and later). We conclude that forced-air warming reduces carbon dioxide accumulation under the drapes in patients undergoing eye surgery under local anaesthesia.

[Self-medication among black African hypertensive patients: Factors and consequences]. / Recours à l'automédication chez l'hypertendu noir africain : ses facteurs et ses conséquences.

INTRODUCTION: Self-medication practice is under-evaluated among black African hypertensive patients. AIM: To assess the level of self-medication among black African hypertensive patients and to determine the factors favoring this practice and their consequences. METHODS: Prospective study during a 3-month period including 612 hypertensive patients followed in Abidjan cardiology institute. RESULTS: Mean age was 55.1. The patients had a self-medication use in 60.1% of cases. Medicinal plants and derived products were commonly involved. Self-medication use reasons were: influence of relatives (89.8%) and the fear of antihypertensive drugs adverses effects (54.9%). Multivariate analysis shows that factors of self-medication were age (56.6 years vs. 50.3 years, P<0.001), income less than 762 euros/month (88% vs. 75.4%; OR=2.73; 95% CI: 1.62-4.6; P<0,0001), obesity (70.4% vs. 35.6%; OR=1.24; 95% CI: 0.75-1.15; P=0.037), dyslipidemia (40.8% vs. 27.9%; OR=6.72; 95% CI: 0.57-2.13; P=0.043), antihypertensive association therapy (61.7% vs. 51.4%; OR=2.27; 95% CI: 0.25-0.97; P=0.037). Poor control of high blood pressure (HBP) was a consequence of self-medication (6.5% vs. 47.1%; OR=10.27; 95% CI: 4.65-56.4; P=0.034), repercussions of HBP on major organ (75% vs. 17.2%; OR=12.9; 95% CI: 8.5-19.6; P=0.0001). CONCLUSION: Self-medication is a common practice in African hypertensive patients. It has many consequences.

[Peripheral arterial disease of the lower limbs in African diabetic patients: ultrasonography and determining factors]. / Artériopathie des membres inférieurs du diabétique noir africain: aspects ultrasoniques et facteurs déterminants.

INTRODUCTION: Diabetic peripheral arterial disease (PAD) of the lower limbs is underdiagnosed. METHODOLOGY: This was a prospective study conducted over a six-month period from November 2012 to April 2013. A total of 308 diabetic patients were included from three diabetes centers in Abidjan (Ivory Coast). AIM: To screen for PAD of the lower limbs in a diabetic population and to identify the determining factors. RESULTS: Among the 308 patients, the ankle-brachial index (ABI) was<0.9 in 68 (22.07%) patients considered to have PAD; the ABI was>1.3 in 56 (18.2%) patients who had suspected mediacalcosis. The average age of the PAD patients was 60.2 years. Female gender predominated (55.9%). The mean duration of diabetes was 9.6 years: 97.1% type 2 diabetes. The other cardiovascular risk factors in this population were hypertension (58.8%) and dyslipidemia (40.9%). Smoking was present in 29.4% of patients and obesity in 23.9%. PAD of the lower limbs was mild in 46 patients (67.6%), moderate in 16 (23.5%) and severe in 6 (8.8%). Duplex Doppler commonly showed lesions of the tibial arteries. Determining factors of diabetic PAD of the lower limbs were hypertension (58.8% vs 36.6%; OR=2.46; 95% CI: 1.13-5.36; P=0.034) and dyslipidemia (40.9% vs 8.3%; OR=7.6; 95% CI: 2.31-25.08; P=0.0009). For mediacalcosis, male gender (71.5% vs 39.7; OR=0.26 95% CI/0.10-0.64. P=0.004) was the only factor identified. CONCLUSION: Hypertension and dyslipidemia were predictive factors for diabetic PAD of the lower limbs in our African population.

[Diagnostic approach and treatment of hypertension in healthcare workers in Abidjan's district (Ivory Coast)]. / Approche diagnostique et prise en charge de l'hypertension artérielle chez le personnel soignant du district d'Abidjan (Côte d'Ivoire).

BACKGROUND: Epidemiological data concerning hypertension among health care workers are scarce. PURPOSE: The aim of this study was to assess the diagnostic process and treatment of hypertension among a healthcare worker population in order to improve treatment. METHODS: This was a prospective study including 821 healthcare workers from Abidjan's publics hospitals. There were 208 medical doctors, 464 nurses and 149 assistant nurses. There were 59% women, 41% men. The mean age was 42.9 years. RESULTS: The prevalence of hypertension was 17.5%: 48.1% among teaching medical doctors, 13.6% in the group of other medical doctors, 14.9% in the nurses group and 18.8% in the assistant nurse group. After recruitment as a healthcare worker, 86.9% of the cases of hypertension were diagnosed. When hypertension was diagnosed, 74.3% had presented symptoms. The disease was diagnosed by a physician in 77.8% of cases and by a nurse in 22%. In many cases (67.8%), the follow-up was done by a cardiologist; 15.7% by general practitioners. However, 10.7% of the healthcare workers with hypertension had no medical follow-up. Single-drug treatment was most commonly used (49.7%); 36.4% were taking two drugs. Poor compliance with treatment was noted in 71.1% of he healthcare workers with hypertension (clearly poor compliance for 40.5% and problems with compliance for 30.6%). Among those with clearly poor compliance, 29% had stopped taking their medication and seven individuals had declined taking any medication. Poor compliance was most commonly observed among assistant nurses (52.9%) and nurses (42.6%). People taking a combination of two or three drugs complied better with their treatment.

Retinal manifestations of patients with human immunodeficiency virus, a multiethnics study in Malaysia.

AIM: To investigate the fundus findings of patients infected with human immunodeficiency virus (HIV) in correlation to Highly Active Antiretroviral Therapy (HAART) and CD4 count. METHODS: Two hundred and two patients of the three major races (Chinese, Malay and Indian) in Malaysia were recruited in this population-based cross-sectional study. This consisted of confirmed HIV sero-positive patients with HAART treatment (n=95) or without HAART therapy (n=107) from December 2007 to March 2008. They were further classified into the HIV infected group, AIDS related complex (ARC) group and AIDS group. Each group was then subdivided according to their CD4 count. Clinical fundus findings were recorded. RESULTS: Sixty six patients (32.7%) showed presence of fundus manifestation, majority of which was HIV microangiopathy (89%) and the rest being Cytomegalovirus (CMV) retinitis (11%). The most common fundus lesion was cotton wool spot (34%). There was a higher incidence of fundus manifestation in the non HAART group than the HAART group (P=0.04) and in patients with CD4 count less than 200 cells/ml in both groups (P=0.01). The HAART therapy had remarkably reduced the percentage of fundus manifestation by 20% but CD4 count remains the marker for fundus manifestations. There were no significant differences noted in the retinal manifestation among the different races. (ANOVA, P=0.25). CONCLUSION: The fundus manifestations were higher in patients with CD4<200 cells/ml and in the non HAART group. Hence the HAART therapy is capable of reducing the incidence of fundus manifestations, however the CD4 count determines the occurrence of fundus manifestations.

Arterial thrombosis in patients with human immunodeficiency virus: two-case reports and review of the literature.

Thrombosis during HIV infection was commonly vein thrombosis. Arterial thrombosis is also more and more described. We report two cases detected in the Abidjan Cardiology Institute. Case Reports. Case 1: an HIV infected female presented with sudden loss of consciousness and right hemiplegia. She had been taking HAART regimen for five years. Neck vessels ultrasonography revealed thrombosis on left ICA. Anticoagulant treatment leads to reduction of symptoms and left ICA partial recanalization. Case 2: male HIV infected taking HAART therapy was admitted for an acute pain of left lower limb; examination showed a decrease of heat, sensitivity, and mobility of this limb with popliteal and tibial pulses abolished. Arterial ultrasonography and CT angiography showed occlusion on the lower third of superficial femoral artery and homolateral popliteal artery suggesting a thrombosis of this artery. He underwent a femorotibial bypass surgery and anticoagulant treatment. The outcome was good with reappearance of local heat of the limb and tibial pulses. Probable etiology is early carotid atherosclerosis associated with protein S deficiency in the first case and antiphospholipid syndrome in the second case. Conclusion. Arterial thrombosis might occur in HIV infection. Several etiological factors could be involved in the pathogeny of these arterial thromboses.

Trait anxiety affects decision-making differently in healthy men and women: towards gender-specific endophenotypes of anxiety.

Excessive levels of trait anxiety are a risk factor for psychiatric conditions, including anxiety disorders and substance abuse. High trait anxiety has been associated with altered cognitive functioning, in particular with an attentional bias towards aversive stimuli. Decision-making is a crucial aspect of cognitive functioning that relies on the correct processing and control of emotional stimuli. Interestingly, anxiety and decision-making share underlying neural substrates, involving cortico-limbic pathways, including the amygdala, striatum and medial and dorsolateral prefrontal cortices. In the present study, we investigated the relationship between trait anxiety, measured by the State-Trait Anxiety Inventory, and complex decision-making, measured by the Iowa Gambling Task, in healthy male and female volunteers. The main focus of this study was the inclusion of gender as a discriminative factor. Indeed, we found distinct gender-specific effects of trait anxiety: in men, both low and high anxiety groups showed impaired decision-making compared to medium anxiety individuals, whereas in women only high anxiety individuals performed poorly. Furthermore, anxiety affected decision-making in men early in the task, i.e. the exploration phase, as opposed to an effect on performance in women during the second part of the test, i.e. the exploitation phase. These findings were related to different profiles of trait anxiety in men and women, and were independent of performance in the Wisconsin Card Sorting Test and cortisol levels. Our data show gender-specific effects of trait anxiety on emotional decision-making. We suggest gender-specific endophenotypes of anxiety to exist, that differentially affect cognitive functioning.

Visual epilepsy in glioblastoma multiforme.

We report a 33-year-old Chinese gentleman who presented with visual epilepsy and symptoms of raised intracranial pressure in which clinical examination revealed normal visual fields and acuity despite Magnetic Resonance Imaging (MRI) brain showing large contrast enhancing mass at the right occipital lobe. Craniotomy and excision of tumour was done and the histology confirmed glioblastoma multiforme (GBM). He completed radiotherapy and recovered well except developing left inferior homonymous quadrantropia post operatively which improved with time.

Von Hippel angioma.

We report a three year follow up of a 35-year-old Indian gentleman who presented with sudden, painless blurring of left (L) eye vision with initial visual acuity (VA) of 6/60. Fundoscopy revealed (L) vitreous haemorrhage and subsequently confirmed a (L) inferotemporal capillary haemangioma. The adjacent area of capillary haemangioma was treated with barricade argon laser photocoagulation to prevent progression of exudative retinal detachment inferiorly. Subsequent follow up showed mild regression of capillary haemangioma with maintenance of (L) eye vision at 6/9.

Immediate pars plana vitrectomy for dislocated intravitreal lens fragments during cataract surgery.

PURPOSE: To assess the outcome of patients who underwent instantaneous pars plana vitrectomy for dislocated lens fragments during cataract surgery. METHODS: The medical records of 29 patients who underwent immediate pars plana vitrectomy for dislocated lens fragments at the same sitting of phacoemulsification surgery were reviewed. Data including patients' demographics, preoperative and postoperative vision, risk factors for lens fragment dislocation, and intraoperative and postoperative complications were recorded. RESULTS: The mean follow-up period of the patients was 12.3 months (range, 3-47 months). The median preoperative visual acuity was 6/90 (range, LP to 6/15). The median final postoperative visual acuity was 6/18 (range, NLP to 6/9) and the mean improvement in vision after the operation was 4.5 lines. The commonest risk factors for dislocation of lens fragment were late detection of posterior capsule tear, splitting of anterior capsulorrhexis, and hard nucleus. After excluding nine eyes with other pre-existing ocular comorbidities, 10 (50%) eyes had a final visual acuity of 6/12 or better. Complications after surgery included three (10%) cases of retinal detachment and one (3%) patient developed epiretinal membrane. None of the patients in the study developed secondary glaucoma or cystoid macular oedema following surgery. CONCLUSION: Immediate vitrectomy in the same sitting of the cataract surgery is a surgical option in the management of dislocated intravitreal lens fragments when vitreoretinal support is available. Most patients achieve a good visual outcome with reduced risk of secondary glaucoma and cystoid macular oedema after surgery.
