Incidence of ophthalmic involvement in Behçet's disease in the United Kingdom: a British Ophthalmic Surveillance Unit (BOSU) study.

BACKGROUND: Behçet's disease (BD) is a relapsing-remitting vasculitis, which can manifest in different organ systems including the eyes. There is currently limited published data describing the incidence of ophthalmic disease within the United Kingdom. The primary aim of this study was to survey the incidence and manifestations of ophthalmic BD prospectively, with a secondary aim of reviewing treatment modalities initiated in first-line therapy. METHODS: Using the British Ophthalmic Surveillance Unit reporting system between October 2016 and November 2018, we prospectively surveyed the number of cases of BD presenting to UK ophthalmologists. A total of 89 cases of ophthalmic manifestations of BD were reported and complete information was collected on 58 patients. RESULTS: 93 eyes of 58 patients were affected. The median age of reported cases was 31 years (range 13-55 years) who were born in 15 different countries. Most cases (n = 35, 60%) had bilateral involvement. Vitritis was the most common ocular manifestation (68%; n = 63) followed by anterior uveitis (46%; n = 43). The greatest causes of visual morbidity were cystoid macular oedema, vitritis and retinal ischaemia. Most patients were prescribed either topical or oral corticosteroids (59%; n = 34), with some given intravitreal or intravenous corticosteroids. Five patients (8.6%) were initiated on disease-modifying anti-rheumatic drugs and one given an anti-TNF monoclonal antibody. CONCLUSIONS: This is the first prospective study to analyse the incidence of ophthalmic involvement in BD over a 2-year period, finding an annual incidence of 0.04 per 100,000 individuals in the UK.

The natural history of conjunctival naevi in children and adolescents.

OBJECTIVE: The objective of this study is to characterise the natural history of conjunctival naevi in a paediatric and adolescent population. METHODS: All children and adolescents referred to Moorfields Ocular Oncology Service for evaluation between January 2015 and 2020 were included. Exclusion criteria included age >20 years old and lack of anterior segment photographs. A total of 77 patients were included with a mean age of 12 years (standard deviation: 3.9; range, 4-20). The main outcome measures were: number of conjunctival naevi that grew, changed in pigmentation, required excisional biopsy, or were histologically malignant. If there was growth, the percentage increase in size was measured. RESULTS: At their first visit, 13% of patients (10/77) were discharged to local follow-up and 10% (8/77) proceeded to excisional biopsy, four further patients underwent excisional biopsy after a period of follow-up. On histopathological assessment, 92% (11/12) of lesions were benign conjunctival naevi. One patient, who had suspicious clinical features at presentation, had conjunctival melanoma. Fifty-nine patients were followed over a median of 1.1 years (interquartile range: 1.54; range, 3 months to 4 years). Eight per cent (5/59) of conjunctival naevi enlarged in diameter by a mean percentage increase in size of 2%, whereas 5% (3/59) showed increased pigmentation and 8.5% (5/59) showed decreased pigmentation. CONCLUSIONS: Growth of conjunctival naevi in children is infrequent (8%) and the large majority of those excised are benign. Because of a lack of evidence, these patients are often followed for years in ophthalmic practice. This series demonstrates that prolonged follow-up may not be necessary.

A Novel Medial Canthal Reconstruction Technique in Children With Blepharophimosis Syndrome.

PURPOSE: There are different techniques for medial canthoplasty in blepharophimosis syndrome where individuals have epicanthus inversus and telecanthus leading to typical facial appearances. These methods have potential problems with scarring, epistaxis, and extrusion of metal plates. METHODS: The authors describe a novel technique of medial canthal reconstruction using titanium microplates with microscrew fixation to the anterior lacrimal crest, with effective, safe, and reproducible results. RESULTS: Seven children with blepharophimosis syndrome underwent medial canthus reconstruction surgery at a single center with the collaboration of a pediatric oculoplastic surgeon and craniofacial plastic surgeon to improve eye opening through correction of the lid contours and telecanthus. CONCLUSIONS: This is a safe, effective, and reproducible technique, with minimal morbidity and rapid postoperative recovery in children. It produces cosmetically acceptable scars and a strong stable reconstruction of the medial canthal insertion.

Success of trabeculectomy surgery in relation to cataract surgery: 5-year outcomes.

AIMS: To compare success proportions at 5 years in three surgical groups: group 1, trabeculectomy alone; group 2, trabeculectomy followed by cataract surgery within 2 years; and group 3, trabeculectomy performed on a pseudophakic eye. METHODS: A retrospective cohort study. 194 eyes of 194 patients were identified with at least 5 years' follow-up post trabeculectomy (N=85, 60 and 49 in groups 1, 2 and 3, respectively). MAIN OUTCOME MEASURES: 1. PRIMARY OUTCOME MEASURE: intraocular pressure (IOP) at 5 years post-trabeculectomy surgery, 2.Secondary outcome measure: change in visual acuity at 5 years. RESULTS: At 5 years, the mean IOP (SD) was 12.9 (3.5), 12.5 (4.8) and 12.7 (4.8) mm Hg in groups 1, 2 and 3, respectively. Overall success was almost identical, 58%, 57% and 59% in groups 1, 2 and 3, respectively. There was no significant difference between the groups in terms of percentage IOP reduction, number of medications, proportion restarting medication and reoperation rates at 5 years. Logistic regression for an outcome of failure showed men to be at increased risk of failure OR 1.97 (95% CI 1.10 to 3.52, p=0.02). Nearly 80% of patients retained or improved their vision following their initial trabeculectomy. CONCLUSIONS: The sequence in which surgery is carried out does not appear to affect trabeculectomy function at 5 years, success being similar to trabeculectomy alone. In our study, men may be at increased risk of failure.

New Health Technologies: A UK Perspective Comment on "Providing Value to New Health Technology: The Early Contribution of Entrepreneurs, Investors, and Regulatory Agencies".

New health technologies require development and evaluation ahead of being incorporated into the patient care pathway. In light of the recent publication by Lehoux et al who discuss the role of entrepreneurs, investors and regulators in providing value to new health technologies, we summarise the processes involved in making new health technologies available for use in the United Kingdom.

The perception of online work-based assessments.

BACKGROUND: Work-based assessments (WBAs) and the associated online feedback are fundamental parts of clinical training. Despite years of clinical use there is little evidence suggesting that they have a positive impact on learning or performance. AIMS: This observational pilot study investigates the perceptions of online WBAs (OnWBAs) across specialties in an attempt to establish why these tools are not meeting their full academic potential. METHODS: Structured questionnaires were given to 90 clinicians. Responses were analysed in excel, and spss 17 was used to test for statistical significance. RESULTS: All responders felt that OnWBAs were a poor reflection of clinical competency, and did not enhance learning significantly. Consultant OnWBAs rated poorly against those performed by other grades. Consultant OnWBAs were significantly more difficult to obtain and took significantly longer to complete than those from other grades. Several consultants were inadequately trained in the use of OnWBAs, and most were unaware of the number of assessments required by trainees. DISCUSSION: This study highlights several issues that may detract from the functionality of OnWBAs. Pockets of consultants are inadequately trained in the use of OnWBAs, and many lack knowledge of trainee requirements. In addition the delay between assessment and completion of feedback is a concern that goes against current recommendations. Simple measures in the workplace and the involvement of educational bodies could remedy some of these issues. Further studies investigating a wider population would help to establish the true extent of the problem and isolate the main causative factors behind these issues.

A rare cause of upper airway obstruction: spontaneous synchronous sublingual and laryngeal haematomas.

Anticoagulation with warfarin is commonly used for prevention of thromboembolic events in patients with atrial fibrillation. Bleeding is the main side effect of anticoagulation. We report the case of a 66-year-old man who developed two spontaneous synchronous upper airway haematomas while on warfarin therapy. To our knowledge, this is the first reported case of a sublingual haematoma presenting simultaneously with supraglottic laryngeal haematomas. Upper airway haematomas are rare in the absence of a history of trauma but need to be urgently assessed due to their life-threatening potential. Clinicians should be aware of the possibility of haematomas involving the upper airway in patients on anticoagulant therapy, particularly if complaining of red flag symptoms such as acute onset dysphonia, odynophagia or airway/breathing difficulties.
