Outcomes of newly referred patients with suspected angle closure: do we need to redefine the clinical pathways?

BACKGROUND/OBJECTIVES: To investigate outcomes of referrals for suspected angle closure and explore whether anterior segment optical coherence tomography (AS-OCT) can be used to tighten triaging criteria in a glaucoma virtual clinic. SUBJECTS/METHODS: Retrospectively collected data. The first audit (04/2018-03/2019) identified referrals for suspected angle closure without other glaucoma-related findings (primary angle closure suspect (PACS) referrals). All patients underwent gonioscopy. The second audit (04-08/2019) identified patients with suspected angle closure in a virtual clinic. Management outcomes were assessed, using gonioscopy as reference standard. The outcomes of the second audit were re-audited after changing the triaging criterion from angle width <10° to iridotrabecular contact (ITC) in ≥1 quadrants on AS-OCT. RESULTS: Out of 1754 glaucoma referrals (first audit), 24.6% (431/1754) were PACS referrals. Of these, only 10.7% (42/393) had an occludable angle on gonioscopy, with 97.6% (41/42) being PACS. Of these, 78% (32/41) underwent laser peripheral iridotomy. Out of 137 referrals in the virtual clinic (second audit), 66.4% (91/137) were triaged to the face-to-face clinic. Of these, 31.9% (29/91) were discharged. AS-OCT had positive and negative predictive value of 74.3% (95% confidence intervals (CI) 57.8-86.0) and 82.1% (95% CI 70.0-90.2%), respectively, in detecting ITC in ≥1 quadrants. In the re-audit 45.9% (45/98) of those with suspected angle closure were triaged for gonioscopy, with 24.4% (11/45) of them being discharged. CONCLUSION: PACS referrals represent a substantial burden to hospital-based services and their accuracy is low. ITC in ≥1 quadrants on AS-OCT can be useful in triaging those who need further evaluation with gonioscopy.

Early post-operative angle as a predictor of surgical success in adult patients with intermittent exotropia.

Purpose: Intermittent exotropia is a condition where divergent strabismus is present at certain times or fixation distances and is surgically treated with bilateral lateral rectus recession or unilateral lateral rectus recession with medial rectus resection. The main purpose of our study is to assess the relationship between the initial post-operative deviation and surgical outcomes in adult exotropes undergoing recess-resect surgery. Methods: A retrospective chart review was performed on adult patients who underwent unilateral recess-resect surgery for intermittent exotropia between March 2010 and February 2022 at a single institution with at least 3 months of follow-up. Based on their motor alignment at 2 weeks following surgery, they were categorized as having exodeviation, esodeviation within 10 PD and esodeviation exceeding 10 PD. Surgical success was defined as motor alignment within 10 PD of exotropia and 5 PD of esotropia at distance and near at final follow-up. Results: 93 patients were included, 55% female and average age was 37 years. At postoperative week 2, 26 patients demonstrated residual exodeviation (Group A), 53 patients demonstrated an esodeviation of within 10 PD (Group B) and 14 patients demonstrated an esodeviation greater than 10 PD (Group C). There were no significant differences in pre-operative and demographic factors between the group. At the final follow-up, surgical success was observed in 57 patients: 12 in Group A, 41 in Group B and 4 in Group C (P < .01). Conclusion: Overcorrection of within 10 PD at 2 weeks following surgery showed a more favorable surgical outcome compared to exodeviation or esodeviation exceeding 10 PD.

Laser-assisted cataract surgery versus standard ultrasound phacoemulsification cataract surgery.

BACKGROUND: Cataract is the leading cause of blindness in the world and, as such, cataract surgery is one of the most commonly performed operations globally. Surgical techniques have changed dramatically over the past half century with associated improvements in outcomes and safety. Femtosecond lasers can be used to perform the key steps in cataract surgery, such as corneal incisions, lens capsulotomy and fragmentation. The potential advantage of femtosecond laser-assisted cataract surgery (FLACS) is greater precision and reproducibility of these steps compared to manual techniques. The disadvantages are the costs associated with FLACS technology. OBJECTIVES: To compare the effectiveness and safety of FLACS with standard ultrasound phacoemulsification cataract surgery (PCS) by gathering evidence from randomised controlled trials (RCTs). SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL; which contains the Cochrane Eyes and Vision Trials Register; 2022, Issue 5); Ovid MEDLINE; Ovid Embase; LILACS; the ISRCTN registry; ClinicalTrials.gov; the WHO ICTRP and the US Food and Drug Administration (FDA) website. We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 10 May 2022. SELECTION CRITERIA: We included RCTs where FLACS was compared to PCS. DATA COLLECTION AND ANALYSIS: Three review authors independently screened the search results, assessed risk of bias and extracted data using the standard methodological procedures expected by Cochrane. The primary outcome for this review was intraoperative complications in the operated eye, namely anterior capsule, and posterior capsule tears. The secondary outcomes included corrected distance visual acuity (CDVA), quality of vision (as measured by any validated patient-reported outcome measure (PROM)), postoperative cystoid macular oedema complications, endothelial cell loss and cost-effectiveness. We assessed the certainty of the evidence using GRADE. MAIN RESULTS: We included 42 RCTs conducted in Europe, North America, South America and Asia, which enrolled a total of 7298 eyes of 5831 adult participants. Overall, the studies were at unclear or high risk of bias. In 16 studies the authors reported financial links with the manufacturer of the laser platform evaluated in their studies. Thirteen of the studies were within-person (paired-eye) studies with one eye allocated to one procedure and the other eye allocated to the other procedure. These studies were reported ignoring the paired nature of the data. There was low-certainty evidence of little or no difference in the odds of developing anterior capsular tears when comparing FLACS and PCS (Peto odds ratio (OR) 0.83, 95% confidence interval (CI) 0.40 to 1.72; 5835 eyes, 27 studies) There was one fewer anterior capsule tear per 1000 operations in the FLACS group compared with the PCS group (95% CI 4 fewer to 3 more).  There was low-certainty evidence of lower odds of developing posterior capsular tears with FLACS compared to PCS (Peto OR 0.50, 95% CI 0.25 to 1.00; 5767 eyes, 26 studies). There were four fewer posterior capsule tears per 1000 operations in the FLACS group compared with the PCS group (95% CI 6 fewer to same).  There was moderate-certainty evidence of a very small advantage for the FLACS arm with regard to CDVA at six months or more follow-up, (mean difference (MD) -0.01 logMAR, 95% CI -0.02 to 0.00; 1323 eyes, 7 studies). This difference is equivalent to 1 logMAR letter between groups and is not thought to be clinically important. From the three studies (1205 participants) reporting a variety of PROMs (Cat-PROMS, EQ-5D, EQ-SD-3L, Catquest9-SF and patient survey) up to three months following surgery, there was moderate-certainty evidence of little or no difference in the various parameters between the two treatment arms. There was low-certainty evidence of little or no difference in the odds of developing cystoid macular oedema when comparing FLACS and PCS (Peto OR 0.84, 95% CI 0.56 to 1.28; 4441 eyes, 18 studies). There were three fewer cystoid macular oedema cases per 1000 operations in the FLACS group compared with the PCS group (95% CI 10 fewer to 6 more).  In one study the incremental cost-effectiveness ratio (ICER) (cost difference divided by quality-adjusted life year (QALY) difference) was GBP £167,620 when comparing FLACS to PCS. In another study, the ICER was EUR €10,703 saved per additional patient who had treatment success with PCS compared to FLACS. Duration ranged from three minutes in favour of FLACS to eight minutes in favour of PCS (I2 = 100%, 11 studies) (low-certainty evidence).  There was low-certainty evidence of little or no important difference in endothelial cell loss when comparing FLACS with PCS (MD 12 cells per mm2 in favour of FLACS, 95% CI -40 to 64; 1512 eyes, 10 studies).  AUTHORS' CONCLUSIONS: This review of 42 studies provides evidence that there is probably little or no difference between FLACS and PCS in terms of intraoperative and postoperative complications, postoperative visual acuity and quality of life. Evidence from two studies suggests that FLACS may be the less cost-effective option. Many of the included studies only investigated very specific outcome measures such as effective phacoemulsification time, endothelial cell count change or aqueous flare, rather than those directly related to patient outcomes. Standardised reporting of complications and visual and refractive outcomes for cataract surgery would facilitate future synthesis, and guidance on this has been recently published.

ANTECEDENTES: La catarata es la principal causa de ceguera en el mundo y, como tal, la cirugía de cataratas es una de las operaciones más realizadas en todo el mundo. Las técnicas quirúrgicas han cambiado radicalmente en el último medio siglo, con las consiguientes mejoras en los desenlaces y la seguridad. Los láseres de femtosegundo se pueden utilizar para realizar los pasos clave de la cirugía de cataratas, como las incisiones corneales, la capsulotomía y la fragmentación del cristalino. La ventaja potencial de la cirugía de cataratas asistida por láser de femtosegundo (FLACS por sus siglas en inglés) es la mayor precisión y reproducibilidad de estos pasos en comparación con las técnicas manuales. Las desventajas son los costes asociados con la tecnología FLACS. OBJETIVOS: Comparar la eficacia y la seguridad de la FLACS con la cirugía de cataratas estándar por facoemulsificación (PCS) con ultrasonido mediante la recopilación de evidencia de ensayos controlados aleatorizados (ECA). MÉTODOS DE BÚSQUEDA: Se realizaron búsquedas en el Registro Cochrane central de ensayos controlados (Cochrane Central Register of Controlled Trials [CENTRAL]; que contiene el Registro de ensayos del Grupo Cochrane de Salud ocular y de la visión [Cochrane Eyes and Vision]; 2022, número 5); en Ovid MEDLINE; Ovid Embase; LILACS; el registro ISRCTN; ClinicalTrials.gov; la ICTRP de la OMS y el sitio web de la Food and Drug Administration (FDA) de los EE. UU. No se aplicaron restricciones de fecha ni de idioma en las búsquedas electrónicas de ensayos. La última búsqueda en las bases de datos electrónicas se realizó el 10 de mayo de 2022. CRITERIOS DE SELECCIÓN: Se incluyeron los ECA en los que la FLACS se comparó con la PCS. OBTENCIÓN Y ANÁLISIS DE LOS DATOS: Tres autores de la revisión examinaron de forma independiente los resultados de la búsqueda, evaluaron el riesgo de sesgo y extrajeron los datos mediante los procedimientos metodológicos estándar previstos por Cochrane. El desenlace principal de esta revisión fueron las complicaciones intraoperatorias en el ojo operado, concretamente, desgarros de la cápsula anterior y posterior. Los desenlaces secundarios incluyeron la agudeza visual corregida a distancia (AVCD), la calidad de la visión (medida por cualquier medida de desenlace notificada por el paciente [PROM] validada), las complicaciones posoperatorias del edema macular cistoide, la pérdida de células endoteliales y la coste­efectividad. La certeza de la evidencia se evaluó mediante el método GRADE. RESULTADOS PRINCIPALES: Se incluyeron 42 ECA realizados en Europa, Norteamérica, Sudamérica y Asia, que reclutaron un total de 7298 ojos de 5831 participantes adultos. En general, los estudios tuvieron riesgo de sesgo incierto o alto. En 16 estudios, los autores informaron vínculos financieros con el fabricante de la plataforma láser evaluada en sus estudios. Trece de los estudios fueron estudios intrapersonales (ojo pareado) con un ojo asignado a un procedimiento y el otro ojo asignado al otro procedimiento. El informe de estos estudios no consideró la naturaleza pareada de los datos. Hubo evidencia de certeza baja de poca o ninguna diferencia en las probabilidades de desarrollar desgarros de la cápsula anterior al comparar FLACS y PCS (odds ratio [OR] de Peto 0,83; intervalo de confianza [IC] del 95%: 0,40 a 1,72; 5835 ojos, 27 estudios). Hubo un desgarro de la cápsula anterior menos por cada 1000 cirugías en el grupo de FLACS en comparación con el grupo de PCS (IC del 95%: 4 menos a 3 más).  Hubo evidencia de certeza baja de menores probabilidades de desarrollar desgarros de la cápsula posterior con FLACS en comparación con PCS (OR de Peto 0,50; IC del 95%: 0,25 a 1,00; 5767 ojos, 26 estudios). Hubo cuatro desgarros de la cápsula posterior menos por cada 1000 cirugías en el grupo de FLACS en comparación con el grupo de PCS (IC del 95%: 6 menos a igual).  Hubo evidencia de certeza moderada de una ventaja muy pequeña en el grupo de FLACS con respecto a la AVCD a los seis meses o más de seguimiento, (diferencia de medias [DM] ­0,01 logMAR; IC del 95%: ­0,02 a 0,00; 1323 ojos, siete estudios). Esta diferencia equivale a 1 letra logMAR entre los grupos y no se considera clínicamente importante. De los tres estudios (1205 participantes) que informaron sobre una variedad de PROM (Cat­PROMS, EQ­5D, EQ­SD­3L, Catquest9­SF y encuesta de pacientes) hasta tres meses después de la cirugía, hubo evidencia de certeza moderada de poca o ninguna diferencia en los diversos parámetros entre los dos grupos de tratamiento. Hubo evidencia de certeza baja de poca o ninguna diferencia en las probabilidades de desarrollar edema macular cistoide al comparar FLACS y PCS (OR de Peto 0,84; IC del 95%: 0,56 a 1,28; 4441 ojos, 18 estudios). Hubo tres casos menos de edema macular cistoide por cada 1000 cirugías en el grupo de FLACS en comparación con el grupo de PCS (IC del 95%: 10 menos a 6 más).  En un estudio, el cociente coste­efectividad incremental (ICER) (diferencia de coste dividida por la diferencia de años de vida ajustados por la calidad [AVAC]) fue de 167 620 GBP al comparar FLACS con SCP. En otro estudio, el ICER fue de 10 703 euros ahorrados por paciente adicional que tuvo un tratamiento exitoso con PCS en comparación con FLACS. La duración varió entre tres minutos a favor de FLACS y ocho minutos a favor de PCS (I 2 = 100%, 11 estudios) (evidencia de certeza baja).  Hubo evidencia de certeza baja de poca o ninguna diferencia importante en la pérdida de células endoteliales al comparar la FLACS con la PCS (DM 12 células por mm 2 a favor de la FLACS; IC del 95%: ­40 a 64; 1512 ojos, 10 estudios).  CONCLUSIONES DE LOS AUTORES: Esta revisión de 42 estudios aporta evidencia de que probablemente haya poca o ninguna diferencia entre la FLACS y la PCS en cuanto a las complicaciones intraoperatorias y posoperatorias, la agudeza visual posoperatoria y la calidad de vida. La evidencia de dos estudios indica que la FLACS podría ser la opción menos coste­efectiva. Muchos de los estudios incluidos solo investigaron medidas de desenlace muy específicas, como el tiempo efectivo de facoemulsificación, el cambio en el recuento de células endoteliales o el brote acuoso, en lugar de las directamente relacionadas con los desenlaces de los pacientes. La notificación estandarizada de las complicaciones y los desenlaces visuales y refractarios de la cirugía de cataratas facilitaría la síntesis futura, y recientemente se han publicado guías al respecto.

Diagnostic features and management options for duodenal neuroendocrine neoplasms: a retrospective, multi-centre study.

Duodenal neuroendocrine neoplasms (dNENs) are rare neoplasms but their incidence is on the rise. They are classified into 5 sub-types but there remains much heterogeneity in behaviour in particular of non-functioning dNENs. To retrospectively analyse outcomes for all types of dNENs, and highlight prognostic factors associated with worse outcome. 102 (57 m/45f.) patients were identified with mean age at diagnosis 62 (range 32-87) years. The majority were non-functioning tumours 87/102 and median size was 10 mm (range 0.9-130 mm). 83 patients had Stage I or II disease, of which 17 underwent endoscopic resection with R1 rate of 45% and complication rate 12%. 36 patients were kept under endoscopic surveillance. There were 11 deaths of which 4 were disease related. Age and Ki67 > 20% were associated with worse OS in all dNENs. In non-functioning dNENs Ki67 > 3% was a predictor of lymph nodes metastases with OR 18.2 (2.54-13) (p < 0.005) in univariate analyses and liver metastases with OR 6.79 (1.56-29.5) (p < 0.05) in the multivariate analysis. Lesions 11-20 mm in size had OR 11.1 (1.16-106) compared to lesions < 11 mm for the prediction of lymph node metastases in the multivariate analysis (p < 0.05). ROC analysis of size of non-functioning dNENs to predict LN metastases found < 15 mm had an AUROC of 0.9 (0.81-0.99) with a sensitivity of 85% and specificity of 88%. dNENs are increasing in incidence, however low grade and smaller lesions have an indolent course and the role of endoscopic resection and active surveillance needs to be reviewed.

Temporal Trends in Childhood Uveitis: Using Administrative Health Data to Investigate the Impact of Health Policy and Clinical Practice.

BACKGROUND: We describe an investigation of temporal trends in the incidence of childhood uveitis-related hospital admissions, hospitalization being a robust indicator of disease severity. METHODS: A population-based retrospective study using a hospitalization database, the Hospital Episode Statistics (HES) dataset, capturing data on care between 2013 and 2020. Primary outcomes were rates of pediatric hospital admissions for uveitis-related disorders. RESULTS: During the study period, there were 3,258 reported uveitis-related hospital admissions of children aged 0 to 14 years, comprising 19% of all-age uveitis-related admissions. Anterior uveitis was the most common diagnosis. The annual incidence of childhood uveitis-related hospitalizations declined year on year from a peak incidence of 5.4 per 100,000 children (95% confidence interval 5.0-5.9) in 2015-2016 to 3.3 per 100,000 (95% CI 3.0-3.6) in 2019-2020. Over the same period, the national incidence of juvenile arthropathy-related admissions stayed stable. CONCLUSION: The decline in admissions nationally may reflect reduced incidence of uveitis complications with increasing use of immunosuppressive therapies.

Incidence and Risk Factors for Macular Atrophy in Acquired Vitelliform Lesions.

PURPOSE: To study the time course to macular atrophy (MA) and associated risk factors in eyes with acquired vitelliform lesions (AVLs) as they vary between patients and between eyes of an individual. DESIGN: Single-center, retrospective, observational cohort study. PARTICIPANTS: Consecutive patients registered between January 2009 and January 2014 with first diagnosis of AVL confirmed by multimodal imaging were included. Eyes with baseline MA or choroidal neovascularization were excluded. METHODS: Patient demographics were collected. Serial OCT scans and fundus autofluorescence (FAF) scans were graded and analyzed. Turnbull's estimator was used, and time was censored at 5 years. Multivariable Weibull parametric proportional hazard models were used to assess the association of risk factors with MA after adjustment for age and gender. Hazard ratios (HRs) are reported with 95% confidence interval (CI). MAIN OUTCOME MEASURES: Time to the first OCT evidence of MA stratified by presenting visual acuity (VA) and AVL lesion subtypes. Secondary outcome included risk factors for incident MA. RESULTS: A total of 237 eyes (132 patients) met the inclusion criteria. Incident MA was detected in 52 of 237 eyes (21.9%) by 5 years. Stratified by baseline VA, 40.3% of eyes with VA ≤70 letters developed atrophy within 5 years of first diagnosis in contrast to 10.3% eyes with VA >70 letters (P < 0.001). Based on lesion type only, 12.9% of eyes with vitelliform lesion at baseline developed MA versus 39.8% and 44.2% of eyes with pseudohypopyon or vitelliruptive lesion type, respectively. In adjusted analysis, baseline factors associated with increased risk of MA included VA ≤70 letters (hazard ratio [HR], 5.54; 95% confidence interval [CI], 2.30-13.34), base width (HR, 1.22; 95% CI, 1.16-1.28), maximum height (HR, 2.61; 95% CI, 1.82-3.74), presence of subretinal drusenoid deposits (SDDs) (HR, 2.83; 95% CI, 1.34-5.96), and disrupted external limiting membrane (ELM) (HR, 2.81; 95% CI, 1.34-5.86). CONCLUSIONS: Baseline VA of ≤70 letters (Snellen ≤20/40) and pseudohypopyon or vitelliruptive lesion type attribute the highest risk for MA. Other prognostic indicators for MA include baseline presence of SDD, disrupted ELM, and larger lesion area.

Prospective deep phenotyping of choroideremia patients using multimodal structure-function approaches.

OBJECTIVE: To investigate the retinal changes in choroideremia (CHM) patients to determine correlations between age, structure and function. SUBJECTS/METHODS: Twenty-six eyes from 13 male CHM patients were included in this prospective longitudinal study. Participants were divided into <50-year (n = 8) and ≥50-year (n = 5) old groups. Patients were seen at baseline, 6-month, and 1-year visits. Optical coherence tomography (OCT), OCT angiography, and fundus autofluorescence were performed to measure central foveal (CFT) and subfoveal choroidal thickness (SCT), as well as areas of preserved choriocapillaris (CC), ellipsoid zone (EZ), and autofluorescence (PAF). Patients also underwent functional investigations including visual acuity (VA), contrast sensitivity (CS), colour testing, microperimetry, dark adaptometry, and handheld electroretinogram (ERG). Vision-related quality-of-life was assessed by using the NEI-VFQ-25 questionnaire. RESULTS: Over the 1-year follow-up period, progressive loss was detected in SCT, EZ, CC, PAF, and CFT. Those ≥50-years exhibited more structural and functional defects with SCT, EZ, CC, and PAF showing strong correlation with patient age (rho ≤ -0.47, p ≤ 0.02). CS and VA did not change over the year, but CS was significantly correlated with age (rho = -0.63, p = 0.001). Delayed to unmeasurable dark adaptation, decreased colour discrimination and no detectable ERG activity were observed in all patients. Minimal functional deterioration was observed over one year with a general trend of slower progression in the ≥50-years group. CONCLUSIONS: Quantitative structural parameters including SCT, CC, EZ, and PAF are most useful for disease monitoring in CHM. Extended follow-up studies are required to determine longitudinal functional changes.

Sector Retinitis Pigmentosa: Extending the Molecular Genetics Basis and Elucidating the Natural History.

PURPOSE: To determine the genetic background of sector retinitis pigmentosa (RP) natural history to better inform patient counseling. DESIGN: Retrospective case series. METHODS: Review of clinical notes, retinal imaging including color fundus photography (CFP), fundus autofluorescence (FAF), optical coherence tomography (OCT), electrophysiological assessment (ERG), and molecular genetic testing were performed in patients with sector RP from a single tertiary referral center. Main outcomes measured were demographic data, signs and symptoms, visual acuity, molecular genetics; and ERG, FAF, and OCT findings. RESULTS: Twenty-six molecularly confirmed patients from 23 different families were identified harboring likely disease-causing variants in 9 genes. The modes of inheritance were autosomal recessive (AR, n=6: USH1C, n=2; MYO7A, n=2; CDH3, n=1; EYS, n=1), X-linked (XL, n=4: PRPS1, n=1; RPGR, n=3), and autosomal dominant (AD, n=16: IMPDH1, n=3; RP1, n=3; RHO, n=10), with a mean age of disease onset of 38.5, 30.5, and 39.0 years old, respectively. Five of these genes have not previously been reported to cause sector RP (PRPS1, MYO7A, EYS, IMPDH1, and RP1). Inferior and nasal predilection was common across the different genotypes, and patients tended to maintain good central vision. Progression on serial FAF was observed in RPGR, MYO7A, CDH23, EYS, IMPDH1, RP1, and RHO-associated sector RP. CONCLUSIONS: The genotypic spectrum of the disease is broader than previously reported. The longitudinal data provided will help to make accurate patient prognoses and counseling as well as inform patients' potential participation in the increasing numbers of trials of novel therapeutics and access to future treatments.

Orbital metastases from neuroendocrine neoplasms: clinical implications and outcomes.

PURPOSE: Neuroendocrine neoplasms (NENs) may rarely metastasise to the orbit. Published data on epidemiology, incidence and preferred treatment is limited. We present the largest cohort of symptomatic and asymptomatic NEN patients with orbital metastases and data on epidemiological parameters, symptoms as well as diagnostic/treatment modalities used. METHODS: We identified patients from our internal NEN database of patients who had also undergone Gallium68-DOTATATE PET (Ga68-DOTA). The diagnosis of orbital metastatic NEN was made on somatostatin receptor imaging and confirmed on a dedicated MRI of orbits. RESULTS: We identified 27 patients of 994 patients evaluated with Ga68-DOTATATE PET imaging during their surveillance monitoring in our department; 15 female, average age at NEN diagnosis 53 years and orbital metastatic NEN diagnosis 59 years. The majority of NEN primaries originated from small bowel (18/27, 66.4%) or pancreas 4/27 (4/27, 14.8%). Hepatic with or without concomitant skeletal metastases were present in 23/27 (85%) of patients. Ocular symptoms and/or signs were evident in 11/27 (41%) of patients. 5/11 symptomatic patients underwent external beam radiotherapy (EBRT) resulting in complete symptoms resolution. The 5-year survival was estimated at 84.1%. CONCLUSIONS: Orbital metastases of NEN have a relatively low prevalence, more commonly associated with small bowel primary. Extraocular muscles are primarily affected, irrespectively of liver disease burden. Survival does not seem to be affected. EBRT is an efficacious treatment modality for both symptom relief and tumour growth control. Administration of peptide receptor radionuclide therapy may occasionally induce temporary ocular symptoms, which resolve following treatment with a short course of steroids.

Sparse scalp hair and vision loss: think hypotrichosis with juvenile macular dystrophy.

Here, we report the diagnostic challenge of a female patient of Russian descent with autosomal recessive hypotrichosis with juvenile macular dystrophy (HJMD). She presented to dermatology age one and a half years with sparse hair growth on her scalp, her parents were reassured this would grow, but it never manifested. She was found to be hypermetropic and prescribed glasses from age 2 but no retinal findings were noted. At age 23 years, the patient undertook an internet search and discovered the association of symptoms pointing towards HJMD. She sought genetic testing, revealing a homozygous missense mutation in Cadherin-3 (CDH3) gene. The patient presented to our Genetic Eye Disease Service at Moorfields Eye Hospital age 27 years, with reduced colour, central distance and near vision. Fundus examination and imaging confirmed atrophic macular changes. Currently, HJMD has no treatment, she wears a wig, UV-protected sunglasses in sunlight and maintains a healthy balanced diet.
