Training in cataract surgery in Spain: analysis of the results of a survey of the European Board of Ophthalmology in a Spanish cohort.

INTRODUCTION: A survey conducted by the European Board of Ophthalmology (EBO) revealed significant differences in the surgical training of the ophthalmology residents in Europe, including a disparity between the sexes and a variation in the experience on cataract surgery (CC) between them. This study is about the Spanish sub-cohort of the survey, and its objective is to present and analyse the peculiarities of ophthalmology training in Spain within the European context, as well as discussing ways to harmonise and improve that training throughout the EU. METHODS: We analyse data of the Spanish participants in the EBO exams, defining subgroups by the Autonomous Communities existing in Spain. RESULTS: 93 of 135 requested participants (68.9%) responded. A 60.2% passed the EBO exam between 2021 and 2022, being mostly women (65.59%) aged 31 years old on average. The 91.4% were right-handed, coming from 13 of the 17 Spanish autonomous communities, although mostly from the Community of Valencia, Madrid and Catalonia. Respectively, 16.1%, 3.2% and 8.7% of the respondents said they have completed 10 or more training sessions on animal eyes, synthetic eyes and through the virtual reality simulator. This training was correlated with greater self-confidence in the management of a posterior capsular tear during surgery (p .025). All respondents manifested to have already performed stages of the CC. The average number of operations reported was 181.6 with regional disparities. A significant difference is observed between the sexes against women (-28.3%, p 0.03). DISCUSSION: Ophthalmologists in Spain, much more than other European countries, have greater opportunities for surgical training, with surgical procedures during the residency, that nearly triples those made by the others. Spanish women refer, like their European colleagues, to be in disadvantage in learning opportunities about cataract surgery. The Simulation Based Medical Education (SBME) allows to respond to the training deficit and complements the training on the patient. Although we demonstrate a significant correlation between the number of procedures carried out and self-confidence to operate simple cases, the SBME would be a complementary tool in self-confidence in front of a complication like capsular rupture. CONCLUSION: Spain massively adopts the model named by us "surgery for all", despite the underrepresentation of women in this area, emphasising a need for cultural change that the SBME could facilitate.

19†Unilateral lateral rectus resection as preferred procedure to treat patients with acquired distance esotropia.

To report the results of a series of patients with acquired distance esotropia (ET) who underwent lateral rectus resection.We retrospectively analysed data from 21 symptomatic patients with acquired esotropia who did not tolerate prisms. Twelve patients had myopic esotropia, 5 patients decompensated esophoria and 4 patients age-related distance esotropia. Patients were divided in two groups; myopic and non myopic. Two patients in each group had undergone surgery to medial recti muscles previously. Near and distance angles were measured over 2 visits. Data were analysed with t-test (paired and unpaired).Average age was 47 (myopes), 77 (distance ET) and 26 years (esophoria). Mean spherical equivalent was -4.00 DS (myopes) and + 1 SD (non myopes). Lateral rectus resection ranged between 6 and 8 mm with an average of 7 mm in the myopic group and between 4 and 8 mm with an average of 6 mm in the non-myopic group.The distance angle was reduced from 19 PD to 6 PD in myopes (mean difference 12 PD, p<0.0001) and from 19 PD to 8 PD in non myopes (mean difference 12 PD, p=0.0011). There was no difference in reduction of distance angle between myopes and non-myopes (p=0.771). All patients had complete resolution of diplopia after surgery without needing prisms. Near angle was also fully corrected in 19 patients. One patient with myopia and one patient with distance esotropia went on to have medial rectus recession.Unilateral lateral rectus resection is an effective procedure for acquired distance esotropia in myopic and non-myopic patients.

Gender may be related to the side of the motor syndrome and cognition in idiopathic Parkinson's disease.

BACKGROUND: and Sex and cognitive profile may be related to the laterality of motor symptoms in idiopathic Parkinson's disease. INTRODUCTION: Parkinson's disease (PD) is well recognised as an inherently asymmetric disease with unilateral onset of motor symptoms. The laterality of motor symptoms may be linked to sex, clinical and demographic variables, and neuropsychological disorders. However, the available data are inconsistent. This study aimed to explore the potential association between the laterality of motor symptoms and clinical and demographic variables and deficits in specific cognitive domains. MATERIAL AND METHODS: We retrospectively recruited 97 participants with idiopathic PD without dementia; 60 presented motor symptoms on the left side and 37 on the right side. Both groups were comparable in terms of age, age at disease onset, disease duration, and severity of the neurological deficits according to the Unified Parkinson's Disease Rating Scale and the Hoehn and Yahr scale. RESULTS: Participants with left-side motor symptoms scored lower on the Schwab and England Activities of Daily Living scale. Our sample included more men than women (67% vs. 33%). Both sexes were not equally represented in the 2 groups: there were significantly more men than women in the group of patients with left-side motor symptoms (77% vs. 23%), whereas the percentages of men and women in the group of patients with right-side motor symptoms were similar (51% vs. 49%). Both groups performed similarly in all neuropsychological tasks, but women, independently of laterality, performed better than men in the naming task. CONCLUSION: We found a clear prevalence of men in the group of patients with left-side motor symptoms; this group also scored lower on the Schwab and England Scale. Female sex was predictive of better performance in the naming task. Sex should always be considered in disorders that cause asymmetric involvement of the brain, such as PD.

Introducción: La enfermedad de Parkinson (EP) es una enfermedad asimétrica en la que los primeros síntomas se presentan solo en un lado del cuerpo. El lado de inicio de la sintomatología puede depender del sexo, de variables clínicas y demográficas y de la presencia de trastornos neuropsicológicos. Sin embargo, la evidencia disponible no es consistente. Nuestro estudio pretende determinar si el lado que presenta síntomas motores tiene alguna relación con variables clínicas y demográficas y con déficits en determinados dominios cognitivos. Materiales y métodos: Incluimos 97 individuos con EP y sin demencia; 60 de ellos tenían síntomas motores en el lado izquierdo y 37 en el lado derecho. Ambos grupos presentaban similitudes en cuanto a edad, edad de inicio de la enfermedad, duración de la enfermedad, y gravedad de los síntomas neurológicos, según la Unified Parkinson's Disease Rating Scale y la Hoehn and Yahr Scale. Resultados: Los participantes con síntomas en el lado izquierdo obtuvieron puntuaciones más bajas en la Escala de Actividades de la Vida Diaria de Schwab y England. Nuestra muestra incluía más hombres que mujeres (67 vs. 33%). Además, la distribución de hombres y mujeres no era equitativa entre los dos grupos; había un número significativamente mayor de hombres en el grupo de pacientes con síntomas en el lado izquierdo (77 vs. 23%), mientras que la distribución por sexo era similar en el grupo de pacientes con síntomas en el lado derecho (51 vs. 49%). No encontramos diferencias en las puntuaciones de ninguna de las pruebas neuropsicológicas entre los grupos. Sin embargo, las mujeres, independientemente del lado afecto, obtuvieron mejores resultados que los hombres en la prueba de denominación. Conclusiones: Los hombres eran mucho más numerosos en el grupo de pacientes con afectación del lado izquierdo; este grupo mostró peores puntuaciones en la escala de Schwab y England...(AU)

Systemic Capillary Leak Syndrome triggered by SARS-CoV2 infection: Case Report and Systematic Review.

Objective: Systemic capillary leak syndrome (SCLS) is a severe condition characterized by the coexistence of hypovolaemic shock, haemococentration, and hypoalbuminaemia, without albuminuria, that may progress to multiorgan failure and an unfavourable outcome. Its development is often triggered by viral infections, such as influenza A virus, but it is unclear whether it is also triggered by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). We aimed to investigated the association between SARS-CoV-2 and SCLS.Method: We present the case of a 55-year-old-woman affected by SARS-CoV-2 infection who developed SCLS. Moreover, we performed a systematic review of the literature to identify any common features with other cases and to describe clinical characteristics and outcomes.Results: We found three other cases of SCLS occurring during SARS-CoV-2 infection in 2020. Taking all cases together, the mean age was 50 years (range 38-63), with a 1:1 gender ratio. Respiratory manifestations were the most common symptom, and all patients required admission to the intensive care unit. The mortality rate was 50%.Conclusions: SARS-CoV-2 infection may trigger SCLS disease, either by an overproduction of proinflammatory cytokines or by direct viral infection of the endothelium. Since SCLS may have a poor prognosis, in every SARS-CoV-2-infected patient presenting the suggestive triad of hypovolaemic shock, haemoconcentration, and hypoproteinaemia, an SCLS diagnosis should be considered and early treatment initiated.

European Stroke Organization guideline for the diagnosis and treatment of cerebral venous thrombosis - endorsed by the European Academy of Neurology.

BACKGROUND AND PURPOSE: Current guidelines on cerebral venous thrombosis (CVT) diagnosis and management were issued by the European Federation of Neurological Societies in 2010. We aimed to update the previous European Federation of Neurological Societies guidelines using a clearer and evidence-based methodology. METHOD: We followed the Grading of Recommendations, Assessment, Development and Evaluation system, formulating relevant diagnostic and treatment questions, performing systematic reviews and writing recommendations based on the quality of available scientific evidence. RESULTS: We suggest using magnetic resonance or computed tomographic angiography for confirming the diagnosis of CVT and not routinely screening patients with CVT for thrombophilia or cancer. We recommend parenteral anticoagulation in acute CVT and decompressive surgery to prevent death due to brain herniation. We suggest preferentially using low-molecular-weight heparin in the acute phase and not direct oral anticoagulants. We suggest not using steroids and acetazolamide to reduce death or dependency. We suggest using antiepileptics in patients with an early seizure and supratentorial lesions to prevent further early seizures. We could not make recommendations concerning duration of anticoagulation after the acute phase, thrombolysis and/or thrombectomy, therapeutic lumbar puncture, and prevention of remote seizures with antiepileptic drugs. We suggest that, in women who have suffered a previous CVT, contraceptives containing oestrogens should be avoided. We suggest that subsequent pregnancies are safe, but use of prophylactic low-molecular-weight heparin should be considered throughout pregnancy and puerperium. CONCLUSIONS: Multicentre observational and experimental studies are needed to increase the level of evidence supporting recommendations on the diagnosis and management of CVT.

Pregnancy outcome after a first episode of cerebral vein thrombosis.

Essentials Little is known about recurrences and pregnancy outcome after cerebral vein thrombosis (CVT). We studied a cohort of pregnant women with CVT. Women with CVT appear at increased risk of late obstetrical complications despite prophylaxis. Risks of recurrent thrombosis and bleeding in women on heparin prophylaxis while pregnant are low. SUMMARY: Background The risk of recurrent thrombosis and bleeding episodes in women with previous cerebral vein thrombosis (CVT) on antithrombotic prophylaxis with low-molecular-weight heparin (LMWH) during pregnancy is not established and little information is available on pregnancy outcome. Objectives The aims of this study were to evaluate the risk of obstetrical complications, recurrent venous thrombosis and bleeding in a cohort of pregnant women on LMWH after a first episode of CVT. In addition, to estimate the relative risk of obstetrical complications, patients were compared with healthy women without thrombosis and with at least one pregnancy in their life. Patients We studied a cohort of 52 patients and 204 healthy women. Results The risk of developing late obstetrical complications was 24% (95% CI, 18-38%), leading to a relative risk of 6.09 (95% CI, 2.46-15.05). The risk of miscarriage was not increased. The higher risk of late obstetrical complications in patients appeared unrelated to a previous history of obstetrical complications, to the carriership of thrombophilia abnormalities, or to the presence of co-morbidities. The incidence of termination observed in patients with thrombophilia was double that observed in those without. No recurrent thrombosis or bleeding episodes were observed. Conclusions Women with previous CVT on LMWH prophylaxis during pregnancy have a low risk of developing recurrent thrombosis or bleeding episodes, but seem to have an increased risk of late obstetrical complications.

Early ficolin-1 is a sensitive prognostic marker for functional outcome in ischemic stroke.

BACKGROUND: Several lines of evidence support the involvement of the lectin pathway of complement (LP) in the pathogenesis of acute ischemic stroke. The aim of this multicenter observational study was to assess the prognostic value of different circulating LP initiators in acute stroke. METHODS: Plasma levels of the LP initiators ficolin-1, -2, and -3 and mannose-binding lectin (MBL) were measured in 80 stroke patients at 6 h only and in 85 patients at 48 h and later. Sixty-one age- and sex-matched healthy individuals served as controls. Stroke severity was measured on admission using the National Institutes of Health Stroke Scale (NIHSS). The outcome was measured at 90 days by the modified Rankin Scale (mRS). RESULTS: Ficolin-1 was decreased in patients compared with controls measured at 6 h (median 0.13 vs 0.33 µg/ml, respectively, p < 0.0001). At 48 h, ficolin-1 was significantly higher (0.45 µg/ml, p < 0.0001) compared to the 6 h samples and to controls. Likewise, ficolin-2 was decreased at 6 h (2.70 vs 4.40 µg/ml, p < 0.0001) but not at 48 h. Ficolin-3 was decreased both at 6 and 48 h (17.3 and 18.23 vs 21.5 µg/ml, p < 0.001 and <0.05, respectively). For MBL no difference was detected between patients and controls or within patients at the different time points. In multivariate analysis, early ficolin-1 was independently associated with unfavorable mRS outcome (adjusted odds ratio (OR): 2.21, confidence interval (CI) 95 % 1.11-4.39, p = 0.023). Early ficolin-1 improved the discriminating ability of an outcome model including NIHSS and age (area under the curve (AUC) 0.95, CI 95 % 0.90-0.99, p = 0.0001). CONCLUSIONS: The ficolins are consumed within 6 h after stroke implicating activation of the LP. Early ficolin-1 is selectively related to 3-month unfavorable outcome.

Hypercoagulability and the risk of myocardial infarction and ischemic stroke in young women.

BACKGROUND: Myocardial infarction (MI) and ischemic stroke (IS) are acute forms of arterial thrombosis and share some, but not all, risk factors, indicating different pathophysiological mechanisms. OBJECTIVE: This study aims to determine if hypercoagulability has a differential effect on the risk of MI and IS. PATIENTS AND METHODS: We reviewed the results from the Risk of Arterial Thrombosis in Relation to Oral Contraceptives study, a population-based case-control study involving young women (< 50 years) with MI, non-cardioembolic IS and healthy controls. From these data, relative odds ratios (ORIS /ORMI ) and their corresponding confidence intervals for all prothrombotic factors that were studied in both subgroups were calculated. RESULTS: Twenty-nine prothrombotic risk factors were identified as measures of hypercoagulability. Twenty-two of these risk factors (21/29, 72%) had a relative odds ratios > 1; for 12 (41%), it was > 2; and for 5 (17%), it was > 2.75. The five risk factors with the largest differences in associations were high levels of activated factor XI (FXI) and FXII, kallikrein, the presence of lupus anticoagulans, and a genetic variation in the FXIII gene. CONCLUSION: In young women, prothrombotic factors are associated more with the risk of IS than with MI risk, suggesting a different role of hypercoagulability in the mechanism leading to these two diseases.

Plasma ADAMTS-13 levels and the risk of myocardial infarction: an individual patient data meta-analysis.

BACKGROUND: Low ADAMTS-13 levels have been repeatedly associated with an increased risk of ischemic stroke, but results concerning the risk of myocardial infarction are inconclusive. OBJECTIVES: To perform an individual patient data meta-analysis from observational studies investigating the association between ADAMTS-13 levels and myocardial infarction. METHODS: A one-step meta-analytic approach with random treatment effects was used to estimate pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) adjusted for confounding. Analyses were based on dichotomous exposures, with the 5th and 1st percentiles of ADAMTS-13 antigen levels as cut-off values. Quartile analyses, with the highest quartile as a reference category, were used to assess a graded association between levels and risk ('dose' relationship). Additionally, we assessed the risk of the combined presence of low ADAMTS-13 and high von Willebrand factor (VWF) levels. RESULTS: Five studies were included, yielding individual data on 1501 cases and 2258 controls (mean age of 49 years). Low ADAMTS-13 levels were associated with myocardial infarction risk, with an OR of 1.89 (95% CI 1.15-3.12) for values below the 5th percentile versus above, and an OR of 4.21 (95% CI 1.73-10.21) for values below the 1st percentile versus above. Risk appeared to be restricted to these extreme levels, as there was no graded association between ADAMTS-13 levels and myocardial infarction risk over quartiles. Finally, there was only a minor synergistic effect for the combination of low ADAMTS-13 and high VWF levels. CONCLUSIONS: Low ADAMTS-13 levels are associated with an increased risk of myocardial infarction.

The management of patients with thyroid eye disease after bilateral orbital 3 wall decompression.

INTRODUCTION: Thyroid eye disease is the most common cause of unilateral and bilateral proptosis in adults. Orbital decompression surgery may cause and/or worsen a pre-existing ocular motility disorder. METHODS: A retrospective review was carried out of all bilateral 3 wall orbital decompressions for severe thyroid eye disease performed between January 2002 and December 2004 by one surgeon. Subsequent surgeries were recorded. RESULTS: Seventy-four patients were identified, 59 (80%) females and 15 (20%) males. Mean age at the time of decompression was 46 years. Fifteen (20%) patients complained of diplopia due to strabismus prior to decompression surgery and 20 (27%) developed new diplopia postsurgery. Twenty patients (27%) required no further intervention following decompression surgery; the remainder underwent an average of 2.5 procedures. Strabismus surgery was performed in 32 (43%) patients. The mean time from the decompression to first strabismus surgery was 12 months. Forty-three (58%) patients underwent lid surgery. The mean time from decompression to first lid surgery was 16 months. CONCLUSION: This study demonstrates how this group of complex patients required multiple surgical procedures within an extended timescale, therefore requiring several in- and outpatient visits.

Gynaecological and obstetrical problems in women with different bleeding disorders.

The aim of this case-control study was to analyse the prevalence of gynaecological, obstetrical and other more general bleeding symptoms in 114 women affected by various inherited bleeding disorders, who were compared with 114 apparently healthy women. Retrospective information were collected by means of two specific questionnaires, one on gynaecological and obstetrical bleeding symptoms, with special focus on the presence of menorrhagia as defined by a pictorial blood loss assessment chart (PBAC); and the other on general bleeding symptoms, whose severity was graded by means of the bleeding score (BS). Compared to normal women, the whole group of women with inherited bleeding disorders had a higher prevalence of excessive bleeding at menarche (25% vs. 5%, P < 0.0001) and menorrhagia (59% vs. 46%, P = 0.06). Affected women also had a higher frequency than controls of general bleeding symptoms that scored as severe by a BS > or = 12 (49% vs. 0%, P < 0.0001). In affected women, the BS increased according to the severity of the haemostasis defect. In conclusions, the BS and the PBAC are simple tools to evaluate the severity of general bleeding symptoms and menorrhagia in women with inherited bleeding disorders. These instruments may help to identify those women for whom a therapeutic intervention is warranted.

The influence of posterior capsule opacification on scanning laser polarimetry.

PURPOSE: To evaluate the influence of posterior capsule opacification (PCO) on GDx parameters in a population of pseudophakic, non-glaucomatous patients who underwent Nd:YAG laser capsulotomy (YLC). METHODS: The posterior capsules were photographed with a Topcon digital camera and each image was then entered into the EPCO 2000 software and evaluated independently by three examiners. The EPCO 2000 software was used to calculate the fibrosis index (FI) and the pearl index (PI) for the central 1.5, 2.5, and 3.5 mm of the posterior capsule. Scanning laser polarimetry was performed with GDx before and after YLC. We compared the GDx readings obtained before and after the YLC using paired Student's t-test. The parameters that varied significantly after YLC were subsequently used for regression analysis. Stepwise multiple linear regression was used to analyse the impact of the change in the amount of FI and PI on change in GDx parameters after YLC. RESULTS: In total, 158 patients were enrolled (74 men, 84 women). The mean age was 69.46+/-8.83 years (range 46-83 years). The interobserver agreement among the three experts was found to be good (repeatability coefficient R=1.51, 1.49, 1.49 for observer A vs B, A vs C, and B vs C respectively). One-sample Student's t-test show no difference between all GDx parameters before and after YLC except for Symmetry, Superior/Nasal ratio, Inferior Ratio, and Temporal-Superior-Nasal-Inferior-Temporal (TSNIT). Stepwise multiple regression showed that the two variables of greatest significance for changes in Symmetry were the FI in the central 1.5 and the PI in the central 3.5 mm (P=0.02). Superior/nasal ratio was shown to be most strongly correlated to the FI in the central 1.5 mm and PI in the central 3.5 mm (P<0.001), whereas the variable of greatest significance to Inferior Ratio was PI in the central 3.5 mm (P=0.03). Finally, TSNIT was most strongly correlated to FI in the central 1.5 mm and FI in the central 2.5 mm (P<0.001). CONCLUSION: Presence of capsular fibrosis seems to be more clinically relevant in the central zone, whereas pearls tend to be clinically significant in the central 3.5 mm area. Hence, it might be worthwhile assessing the amount of PCO in pseudophakic patients when performing scanning laser polarimetry. Investigators should ensure that the type of PCO and the size of the area analysed are documented in the notes in order to interpret GDx findings appropriately.

Refractive outcomes after primary intraocular lens implantation in infants.

BACKGROUND: Intraocular lens (IOL) implantation is becoming increasingly accepted as a primary procedure in infants. AIM: To evaluate the accuracy of IOL power calculation, the rate of myopic shift and the refractive outcome after primary IOL implantation in infants aged <12 months at the time of cataract surgery. METHOD: A retrospective case review of 25 patients (8 with bilateral cataracts and 17 with unilateral cataracts) who underwent cataract surgery with primary IOL implantation at <12 months of age. Outcomes measured were actual early postoperative refraction, lens power calculation error, myopic shift and refractive outcome. RESULTS: In 83% of cases, actual postoperative refraction was within 2 dioptres (D) of the target refraction. Lens power calculation error did not depend on axial length, age at surgery or target refraction. Mean (SD) myopic shift was 5.43 (3.7) D in the first 12 months after surgery, but was significantly greater when surgery was performed at <10 weeks of age. CONCLUSION: This study demonstrates that IOL power can be calculated with reasonable accuracy in infants using current formulas. Factors such as age at the time of surgery, axial length, whether surgery is unilateral or bilateral, and the presence of systemic pathologies do not seem to influence the accuracy of lens power calculation or myopic shift up to 36 months of age.

A comparison of clinical performance between disposable and Goldmann tonometers.

PURPOSE: Applanation tonometry as performed in routine clinical practice is a significant potential vehicle for cross-infection particularly in an emergency eye care setting. The aim of this study is to evaluate the accuracy and reliability of three single-use devices (Tonoshield, Tonosafe, Tonojet) as an alternative to standard Goldmann prisms in an emergency eye department. METHODS: All patients attending the eye casualty at the Manchester Royal Eye Hospital for a period of 4 months who required intraocular pressure measurement were eligible for this prospective study. Exclusion criteria were: age below 18 years, corneal anomalies that might affect measurement, and refusal to participate. After taking informed consent, the patient was examined by one experienced nurse practitioner, who measured the intraocular pressure three times. In the first part of the study, we compared the standard Goldmann prism vsTonoshield and Tonosafe prisms, while for the second part of the study we used standard Goldmann, Tonosafe, and Tonojet prisms. Agreement and repeatability tests were carried out on separate samples. RESULTS: Tonosafe and Tonojet correlated well with standard Goldmann tonometry (P<0.001), while the measurements obtained with Tonoshield were higher, especially for raised intraocular pressure measurements. Tonojet and Tonosafe measurements were more reproducible than Tonoshield measurements. CONCLUSIONS: This study shows that Tonosafe and Tonojet are accurate and reliable alternatives to standard Goldmann tonometry.

Open globe injuries: factors predictive of poor outcome.

OBJECTIVE: Despite advances in ocular and orbital imaging, instrumentation, materials, and surgical procedures, the management of open globe injuries continues to pose difficult management dilemmas. In this retrospective study, we identify clinical characteristics and outcome of a series of open globe injuries presenting to a major UK centre. METHOD: Operating department records were reviewed to identify all patients who had undergone repair of an open globe injury from 1 January 1998 to 1 January 2003 at the Manchester Royal Eye Hospital. Case notes were examined to determine demographic data, mechanisms of injury, influence of alcohol/drugs, and location of injury. The Snellen visual acuity on presentation and initial clinical signs were recorded. RESULTS: In total, 115 cases of open globe injury were identified of which 107 cases notes were available for review. Injury to the eye with a sharp object accounted for 71/107 (66%) cases and blunt mechanisms for 30/107 (28%) cases. In six (6%) cases the cause of injury was unknown. The rate of secondary enucleation in our series of 107 open globe injuries was 13/107 (12%). Significant risk factors on presentation associated with eventual enucleation included relative afferent pupillary defect (P<0.001), absence of a red reflex (P<0.001), presence of a lid laceration (P<0.02), a blunt mechanism of injury (P<0.02), and an initial VA worse than 6/60 (P=0.03). CONCLUSION: From this retrospective study, we have identified several factors that may aid the clinician in deciding on the prognostic value of primary repair. Blunt injuries associated with adnexal trauma, with poor initial visual acuity, the presence of an RAPD or retinal detachment, and the absence of a red reflex are associated with a significantly higher rate of subsequent enucleation.

Mortality following exenteration for malignant tumours of the orbit.

BACKGROUND: Orbital exenteration is a rare, but disfiguring procedure reserved for the treatment of locally invasive malignancy or potentially life threatening orbital neoplasms, when less destructive techniques are inadequate. The authors report their experience and analyses of 64 cases of orbital exenteration performed over a 13 year period, looking specifically at key factors affecting mortality associated with such a destructive surgical procedure. METHODS: Records were reviewed retrospectively of all patients who had undergone exenteration of the orbit from 1 January 1991 to 1 April 2004 inclusive, at the Manchester Royal Eye Hospital. In all cases of deceased individuals, the cause of death was determined by liaison with the general practitioner and local health authority. Duplicate death certificates were requested for all deceased patients from the Registrar for Births, Deaths, and Marriages, Southport, UK. Kaplan-Meier analysis was used to estimate survival following exenteration. RESULTS: Overall, 1 year survival post-exenteration was high at 93%. After 3 years this had fallen to 67%, followed by 57% after 5 years, and 37% at 10 years. 13 patients died as a direct result of the orbital tumour. A further nine died of unrelated medical conditions, and two patients succumbed to malignant processes originating elsewhere in the body. There was no difference in survival rate at 3 years (p=0.99) and 5 years (p=0.454) between those with clear resection margins and those without. CONCLUSION: In this study it was found that there was an overall mortality rate of 38% over 12 years. The presence of clear surgical margins, although reassuring for the surgeon, should not be regarded as an indication of cure. However, an overall 1 year survival of 93% and a 10 year survival of 37% are reassuring in that a proportion of individuals achieve surgical cure following exenteration. 38% of patients died as a result of other medical causes over the 12 year follow up.

Acute and chronic effects of brimonidine 0.2% on intraocular pressure and pulsatile ocular blood flow in patients with primary open-angle glaucoma: an open-label, uncontrolled, prospective study.

BACKGROUND: Brimonidine has been reported to decrease aqueous production and increase uveoscleral outflow; however, the hemodynamic effects of brimonidine are still under investigation. OBJECTIVE: The purpose of this study was to report the acute and chronic effects of brimonidine 0.2% on intraocular pressure (IOP) and pulsatile ocular blood flow (pOBF) in patients with primary open-angle glaucoma (POAG). METHODS: Nonsmoking patients aged 45 to 67 years with POAG and normal blood pressure, heart rate, body mass index, and hemorheologic parameters were enrolled in the study. Brimonidine 0.2% was self-administered twice daily for 180 days. IOP and pOBF were determined using Goldmann applanation tonometry and the Langham system. All measurements were taken at baseline and 4, 8, and 12 hours after treatment and were repeated on days 7, 15, 30, 60, 90, 120, 150, and 180 of treatment. RESULTS: Of the 18 eligible patients, 10 (6 men and 4 women) were enrolled (mean age, 51.5 +/- 4.39; range, 47-64 years). When measured 12 hours after instillation, mean IOP was significantly reduced by 21.5% (P < 0.001) compared with the baseline value. The greatest decrease in IOP (-23.5%) was observed at 8 hours. After 12 hours, a significant increase (P < 0.001) in pOBF was measured. A stable IOP reduction (P < 0.001 vs baseline), as well as an increase in pOBF (P = 0.015), was recorded at the subsequent time points. The pOBF increases ranged from 22.5% at day 30 to 9.2% at day 180 of treatment. No evidence of adverse events was found at any time point. CONCLUSIONS: In this sample of patients with open-angle glaucoma, brimonidine induced a rapid reduction in IOP that was significant even after 6 months. Moreover, an increase in pOBF was observed from the first day of treatment, and remained consistent throughout the study.
