Multimodal Imaging in a Case of Peripapillary Choroidal Neovascular Membrane Associated With Idiopathic Intracranial Hypertension.

ABSTRACT: Optical coherence tomography angiography is one of the latest noninvasive imaging modalities for visualizing the vasculature of retina and choroid. We describe its application in the diagnosis, treatment, and monitoring of a patient with peripapillary choroidal neovascular membrane in the setting of idiopathic intracranial hypertension, who responded well to a course of ranibizumab intravitreal injections.

Prevalence and Correlates of Intimate Partner Violence Experience Among Partners of Naval Personnel in Lagos, Nigeria.

BACKGROUND: Military personnel are one of the high risk groups recognized as perpetrators of intimate partner violence (IPV). Little is known about IPV experience of partners of naval personnel. This study determined the prevalence and correlates of IPV experience among partners of naval personnel. METHODS: A cross-sectional survey of 435 male and female partners of naval personnel selected using the multistage sampling technique from the Navy Barracks in Lagos, Nigeria was conducted. Data were collected using a 40 item interviewer-administered questionnaire between August and September 2017. Univariate, bivariate and multivariate analysis was done to identify the predictors of partners' experience of IPV. Analysis was done at p-value ≤0.05. RESULTS: The mean age of the respondents was 32.7 ± 7.86yrs and 72% were females. The lifetime prevalence of any IPV experience was 40.7% (with 74.4% of this experienced by females, CI: 0.81-1.91). The prevalence of controlling behaviour, psychological, sexual, economic and physical IPV were 31.5%, 16.3% 12.4%, 12.0% and 8.5% respectively. There was a positive association between experience of IPV and respondents' occupational status (p < 0.0001), lifetime experience of physical (p < 0.0001), sexual abuse (<0.0001), and history of childhood abuse (p < 0.0001). After adjustment for confounders, age (AOR = 2.11, CI = 1.07-4.16), occupational status (AOR = 4.56, CI = 2.30-9.02), history of childhood abuse (AOR = 2.10, CI = 1.26-3.49,) and partners' alcohol use (AOR = 3.41, CI = 1.38-8.39) remained significant factors influencing experience of IPV. CONCLUSION: The prevalence of IPV experience among partners of naval personnel was high. Being unemployed, experience of abuse in childhood and having a partner who consumed alcohol increased partners' vulnerability to IPV. Naval personnel would benefit from marital counseling and training on non-violence conflict resolution strategies.

Radiotherapy for neovascular age-related macular degeneration.

BACKGROUND: Radiotherapy has been proposed as a treatment for new vessel growth in people with neovascular age-related macular degeneration (AMD). OBJECTIVES: To examine the effects of radiotherapy on neovascular AMD. SEARCH METHODS: We searched CENTRAL, MEDLINE, Embase, LILACS and three trials registers and checked references of included studies. We last searched the databases on 4 May 2020.  SELECTION CRITERIA: We included all randomised controlled trials in which radiotherapy was compared to another treatment, sham treatment, low dosage irradiation or no treatment in people with choroidal neovascularisation (CNV) secondary to AMD. DATA COLLECTION AND ANALYSIS: We used standard procedures expected by Cochrane. We graded the certainty of the evidence using GRADE. We considered the following outcomes at 12 months: best-corrected visual acuity (BCVA) (loss of 3 or more lines, change in visual acuity), contrast sensitivity, new vessel growth, quality of life and adverse effects at any time point.  MAIN RESULTS: We included 18 studies (n = 2430 people, 2432 eyes) of radiation therapy with dosages ranging from 7.5 to 24 Gy. These studies mainly took place in Europe and North America but two studies were from Japan and one multicentre study included sites in South America. Three of these studies investigated brachytherapy (plaque and epimacular), the rest were studies of external beam radiotherapy (EBM) including one trial of stereotactic radiotherapy. Four studies compared radiotherapy combined with anti-vascular endothelial growth factor (anti-VEGF) with anti-VEGF alone. Eleven studies gave no radiotherapy treatment to the control group; five studies used sham irradiation; and one study used very low-dose irradiation (1 Gy). One study used a mixture of sham irradiation and no treatment. Fifteen studies were judged to be at high risk of bias in one or more domains. Radiotherapy versus no radiotherapy There may be little or no difference in loss of 3 lines of vision at 12 months in eyes treated with radiotherapy compared with no radiotherapy (risk ratio (RR) 0.82, 95% confidence interval (CI) 0.64 to 1.04, 811 eyes, 8 studies, I2 = 66%, low-certainty evidence). Low-certainty evidence suggests a small benefit in change in visual acuity (mean difference (MD) -0.10 logMAR, 95% CI -0.17 to -0.03; eyes = 883; studies = 10) and average contrast sensitivity at 12 months (MD 0.15 log units, 95% CI 0.05 to 0.25; eyes = 267; studies = 2). Growth of new vessels (largely change in CNV size) was variably reported and It was not possible to produce a summary estimate of this outcome. The studies were small with imprecise estimates and there was no consistent pattern to the study results (very low-certainty evidence). Quality of life was only reported in one study of 199 people; there was no clear difference between treatment and control groups (low-certainty evidence). Low-certainty evidence was available on adverse effects from eight of 14 studies. Seven studies reported on radiation retinopathy and/or neuropathy. Five of these studies reported no radiation-associated adverse effects. One study of 88 eyes reported one case of possible radiation retinopathy. One study of 74 eyes graded retinal abnormalities in some detail and found that 72% of participants who had radiation compared with 71% of participants in the control group had retinal abnormalities resembling radiation retinopathy or choroidopathy. Four studies reported cataract surgery or progression: events were generally few with no consistent evidence of any increased occurrence in the radiation group. One study noted transient disturbance of the precorneal tear film but there was no evidence from the other two studies that reported dry eye of any increased risk with radiation therapy. None of the participants received anti-VEGF injections. Radiotherapy combined with anti-VEGF versus anti-VEGF alone People receiving radiotherapy/anti-VEGF were probably more likely to lose 3 or more lines of BCVA at 12 months compared with anti-VEGF alone (RR 2.11, 95% CI 1.40 to 3.17, 1050 eyes, 3 studies, moderate-certainty). Most of the data for this outcome come from two studies of epimacular brachytherapy (114 events) compared with 20 events from the one trial of EBM. Data on change in BCVA were heterogenous (I2 = 82%). Individual study results ranged from a small difference of -0.03 logMAR in favour of radiotherapy/anti-VEGF to a difference of 0.13 logMAR in favour of anti-VEGF alone (low-certainty evidence). The effect differed depending on how the radiotherapy was delivered (test for interaction P = 0.0007). Epimacular brachytherapy was associated with worse visual outcomes (MD 0.10 logMAR, 95% CI 0.05 to 0.15, 820 eyes, 2 studies) compared with EBM (MD -0.03 logMAR, 95% CI -0.09 to 0.03, 252 eyes, 2 studies). None of the included studies reported contrast sensitivity or quality of life. Growth of new vessels (largely change in CNV size) was variably reported in three studies (803 eyes). It was not possible to produce a summary estimate and there was no consistent pattern to the study results (very low-certainty evidence). For adverse outcomes, variable results were reported in the four studies. In three studies reports of adverse events were low and no radiation-associated adverse events were reported. In one study of epimacular brachytherapy there was a higher proportion of ocular adverse events (54%) compared to the anti-VEGF alone (18%). The majority of these adverse events were cataract. Overall 5% of the treatment group had radiation device-related adverse events (17 cases); 10 of these cases were radiation retinopathy. There were differences in average number of injections given between the four studies (1072 eyes). In three of the four studies, the anti-VEGF alone group on average received more injections (moderate-certainty evidence). AUTHORS' CONCLUSIONS: The evidence is uncertain regarding the use of radiotherapy for neovascular AMD. Most studies took place before the routine use of anti-VEGF, and before the development of modern radiotherapy techniques such as stereotactic radiotherapy. Visual outcomes with epimacular brachytherapy are likely to be worse, with an increased risk of adverse events,  probably related to vitrectomy. The role of stereotactic radiotherapy combined with anti-VEGF is currently uncertain. Further research on radiotherapy for neovascular AMD may not be justified until current ongoing studies have reported their results.

An online glaucoma educational course for patients to facilitate remote learning and patient empowerment.

In both face-to-face and teleophthalmology glaucoma clinics, there are significant time constraints and limited resources available to educate the patient and their carers regarding the glaucoma condition. Glaucoma patients are often not satisfied with the content and amount of information they receive and have demonstrated a substantial lack of knowledge regarding their condition. Innovative educational tools that facilitate accessible digital remote patient education can be a powerful adjunct to empower patients in becoming healthcare partners.We describe the development of a free, comprehensive, multimodal online glaucoma patient education course for adults with glaucoma, their family and friends and carers, with the aim of providing a readable resource to aid remote learning and understanding of the condition.The working group for the development of the course comprised of consultants, medical practitioners and education specialists and expert patients. Given the specialised nature of ophthalmology and glaucoma, certain aspects can be difficult to conceptualise, and, therefore, clear and adequate explanations of concepts are provided in the course using diagrams, flow charts, medical illustrations, images, videos, written text, analogies and quizzes.The course is available in a short and long version to suit different learning needs which take approximately 2 hours and 10 hours to complete respectively. The contents list allows course takers to find sections relevant to them and it can be taken anywhere, as long as there is Internet access.We invite you to share this resource with your patients and their families, friends and carers.

A novel case of ocular cicatricial pemphigoid induced by levamisole-adulterated cocaine.

AIM: To report a case of ocular cicatricial pemphigoid caused by levamisole-adulterated cocaine. METHODS: Case report. RESULTS: A 54-year-old woman with multi-systemic levamisole-induced vasculitis which triggered bilateral cicatrizing conjunctivitis refractory to conventional immunosuppressants due to continued cocaine misuse. CONCLUSION: Levamisole-induced vasculitis is a significant public health issue due to its popularity as an adulterant to cocaine. Our report suggests that levamisole caused vasculitis and ocular cicatricial pemphigoid in this case. Ocular manifestation of this syndrome is rare.

A New WATCHMAN Sizing Algorithm Utilizing Cardiac CTA.

BACKGROUND: The WATCHMAN left atrial appendage (LAA) occlusion device has emerged as an alternative for anticoagulation in patients with non-valvular atrial fibrillation who cannot tolerate oral anticoagulation therapy. Cardiac computed tomography (CTA) is increasingly being utilized to guide WATCHMAN device sizing, however no consensus algorithm exists. We present our experience with a new cardiac CTA LAA ostium area based sizing algorithm. METHODS: This is a single center, prospective study analyzing consecutive patients who underwent cardiac CTA and WATCHMAN device implantation between March 2017 and October 2019 at University Hospitals Cleveland Medical Center. Patients baseline characteristics, procedural data, and clinical outcomes were collected and analyzed. RESULTS: 115 patients were included in our study. The mean age of our population was 76.5 years ±8.3 years. 70.4% of our patients had preserved ejection fraction. The predominant indication for device implantation was gastrointestinal bleeding in 57.4% of patients. The mean CHADSVASC score was 4.68 ± 1.4. The procedure success rate was 99.1% and the mean number of device used per case of 1.15 ± 0.4 devices. Our CTA LAA ostium area based sizing algorithm accurately predicted the final deployed WATCHMAN device size in 95.6% of cases. CONCLUSION: Our study demonstrates that cardiac CTA LAA ostium area based sizing algorithm is highly accurate at predicting WATCHMAN device size and demonstrates excellent clinical outcomes with lower device utilization per case than what is reported in literature.

Corneal and Scleral Problems Caused by Skin-Lightening Creams.

PURPOSE: To present a case series of patients with corneal and scleral changes associated with the use of skin-lightening creams. This is the first report of corneal changes with these widely available creams. METHODS: Three patients of West African origin presented with strikingly similar skin, corneal, and scleral changes and were found to have all been using skin-lightening creams containing hydroquinone. Histopathology was obtained for 1 patient. RESULTS: Three patients were referred to the corneal clinics of 2 hospitals with corneal changes and a history of blurred vision for 1 to 3 years. There was a 60-year-old woman from Nigeria and a 68-year-old woman and a 73-year-old man both from Ghana. All 3 had been using skin-lightening lotions containing hydroquinone on their faces for between 3 and 15 years and had black-blue facial pigmentation of exogenous ochronosis, a recognized complication of these creams. Their corneas all had horizontal striae radiating across the posterior corneas with scleral thinning and plaques. Linear brown epithelial pigmentation was observed within the lower third of the corneas. Biopsy of the sclera in 1 patient showed ochronosis. CONCLUSIONS: We present previously unreported eye changes associated with the use of skin-lightening creams containing hydroquinone, with a triad of signs: posterior corneal striae radiating from 3 o'clock to 9 o'clock, thinning and plaques in the sclera, and a normal endothelial cell count. Similar pathological changes are seen in exogenous ochronosis, a recognized skin complication of hydroquinone, are seen in the sclera.

Rotational Atherectomy and Mechanical Support to Treat Left Main.

We describe a complex percutaneous coronary intervention using rotational atherectomy (Rotablator, Boston Scientific, Marlborough, Massachusetts) and mechanical circulatory support (Impella, Abiomed, Danvers, Massachusetts) in a patient with multiple comorbidities scheduled to undergo a left main coronary percutaneous coronary intervention using a 2-stent technique based on angiography. However, intracoronary optical coherence tomography changed our strategy to a successful single-stent procedure. (Level of Difficulty: Advanced.).

A depiction of imported malaria in Connecticut.

In 2010, there were roughly 219 million cases of malaria reported worldwide resulting in an estimated 660,600 deaths [1]. In contrast, the total number of cases according to the Centers for Disease Control and Prevention (CDC) in the United States (USA) was only 1691 [2]. Of those, 1688 were cases of imported malaria [2]. This is the highest number of cases reported in U.S. since 1980 [2]. Here, we describe a case of imported malaria and conduct a retrospective case series at four Connecticut (CT) hospitals in order to describe the demographics of imported malaria and to identify potential barriers to timely diagnosis and treatment.
