RESUMO
BACKGROUND: We evaluated health care costs in patients with childhood onset visual impairment caused by inherited retinal dystrophies (IRD). METHODS: The IRD cohort, identified from the Danish Registry of Blind and Partially Sighted Children, was compared to age- and sex-matched controls from the national, Danish population registry. Information on health care expenditures for somatic and psychiatric in- and outpatient services, purchase of prescription medications and paid assistance at home were obtained from national registries for the years 2002-2017. RESULTS: We included 412 in the IRD cohort (6,290 person years) and 1656 (25,088 person years) in the control cohort. Average, annual health care expenditures from age 0-48 years of age were 1,488 (SD 4,711) in the IRD cohort and 1,030 (4,639) in the control cohort. The largest difference was for out-patient eye care (13.26 times greater, 95% confidence interval 12.90-13.64). Psychiatric in-patient expenditures were 1.71 times greater (95% CI 1.66-1.76) in the IRD cohort but psychiatric out-patient health care costs were comparable between groups. CONCLUSIONS: Health care costs were approximately 40% greater in the IRD cohort compared to an age- and sex-matched sample from the general Danish population. This is relevant in the current situation with a number of trials aimed at treating IRDs using genetically based therapies. Although eye care expenditures were many times greater, they made up < 10% of the total health care expenditures even in the IRD cohort. The reduced costs related to injuries in the visually impaired cohort was a surprising finding but may reflect a reduced propensity to seek medical care rather than a reduced risk of injuries.

PURPOSE: The aim of the study was to describe the temporal changes in causes and prevalence of childhood visual impairment in Denmark based on the National Danish Registry of Children with Visual Impairment (NDRCVI). METHODS: Annual reports on the NDRCVI since its establishment in 1979 were reviewed and data on the number of registered children and the causes for registration with a visual impairment were evaluated. RESULTS: The average annual incidence of childhood visual impairment in Denmark is 2.8 per 1000 live-born children and the prevalence of childhood visual impairment is 1.6 per 1000 children <18 years. Today, fewer children are severely visually impaired (visual acuity ≤6/60) at the time of registration (31.6% since 2010 vs. 51.1% in the 1980s). Cerebral visual impairment and optic nerve atrophy have remained common causes of childhood visual impairment whereas sequelae to retinopathy of prematurity have been almost eliminated as a cause. Systemic comorbidities are more common now in children with visual impairment (seen in 63.9% in the last decades vs. 44.6%in the 1980-ties). CONCLUSION: Whereas the prevalence of visual impairment has remained relatively stable over the years, the severity of visual impairment has improved, suggesting that more children will be able to live an active life supported by aids compensating vision loss. However, more children have systemic comorbidities in combination with their visual impairment suggesting that children with visual impairment face a life not only limited by the obstacles of poor vision. This calls for multidisciplinary management and support of affected children and families.
RESUMO
PURPOSE: Rhino-orbital-cerebral mucormycosis (ROCM) is a rare opportunistic infection with a high mortality despite relevant treatment. OBSERVATIONS: A 3-year-old girl under treatment for acute lymphoblastic leukemia developed periorbital swelling, ophthalmoplegia and a necrotic palatal lesion during a period of neutropenia. Imaging revealed sinusitis, pre- and postseptal cellulitis. The disease later progressed to cerebral involvement and orbital apex syndrome with complete ophthalmoplegia, ptosis and loss of vision. The patient was treated with systemic antifungal therapy, hyperbaric oxygen and extensive surgery. This included orbital exenteration, skull base resection, cerebral debridement with placement of an Ommaya reservoir for intrathecal administrations of amphotericin B (AmB) and in addition endoscopic sinus surgery with local AmB installation. Chemotherapy was safely continued after resolution of the ROCM and the patient remains in complete remission after 5 years. CONCLUSION AND IMPORTANCE: Patients with ROCM can be cured with aggressive multimodality treatment, including surgical intervention, even if in myelosuppression.
RESUMO
PURPOSE: To investigate outcomes of routine vision screening compared to as-indicated ophthalmological investigation of all children born preterm in a Danish region from 1997 to 2014. METHODS: All children born preterm (gestation age < 32 weeks or birthweight < 1500 g) screened for retinopathy of prematurity (ROP) were divided into two groups. From 1997 to 2009, only children treated for ROP or referred for visual problems received ophthalmological investigation (as-indicated group). From 2010 to 2014, all ROP-screened infants were offered ophthalmological investigation at 6 months and 3 years of age (screening group). RESULTS: A total of 560 children were included in the as-indicated period, 41 and 87 were referred for ophthalmological investigation at 6 months and 3 years, respectively. In the screening period, 295 children were included, 251 and 150 of whom underwent vision evaluation at 6 months and 3 years, respectively. Mean visual acuity was 4.1 cycles per degree with Teller acuity cards at 6 months and 0.78 decimal at 3 years. At 3 years, 2.7%(n = 11) in the as-indicated versus 3.5%(n = 10) screening group had visual acuity < 6/18 (p = 0.24). Cerebral palsy (n = 28) and epilepsy (n = 5) were significantly related to vision impairment (p = 0.001/0.006), while treated ROP was not (n = 13). Refractive error was common at 3 years (61%), especially astigmatism (50%). Gestational age, birthweight and ROP were not associated with vision impairment or refractive error. CONCLUSION: Screening preterm children at 6 months and 3 years did not reveal more visually impaired children compared to examination when indicated.

PURPOSE: The aim of this study was to provide a population-based estimate on the prevalence of infantile nystagmus and to describe the causes in the Capital Region of Denmark. METHODS: Review of medical records of children with infantile nystagmus born in the period 1 January 2010 through 31 December 2017 and living in the Capital Region of Denmark. We used birth registry data from Statistics Denmark and the National Danish Birth Registry to calculate the prevalence of nystagmus in children born at term and prematurely. RESULTS: A total of 103 patients (52 males/51 females) with infantile nystagmus were included. The overall prevalence of infantile nystagmus was 6.1 per 10 000 live births. It was higher in premature children (28.4/10 000 live births) than children born at term (4.4/10 000), p < 0.0001, and highest in children born extremely preterm, (97.3/10 000). The most common cause of infantile nystagmus was ocular disease (44%) followed by idiopathic nystagmus (32%), neurological disorders and genetic syndromes (20%) and prematurity without retinopathy of prematurity as the only cause (4%). CONCLUSIONS: In this study, we provide the prevalence of infantile nystagmus based on national medical records in which all residents are accounted for. Our findings show a prevalence of 6.1 per 10 000 live births but six times higher among children born preterm than born at term. Ocular disease was the leading cause of infantile nystagmus with albinism and ocular malformations as the most frequent. In 1/3 of patients, no cause could be identified.
RESUMO
PURPOSE: Craniopharyngioma often causes visual loss due to the close relation to the anterior visual pathways. This study investigates the incidence and predictors of visual outcomes in patients with craniopharyngioma. METHODS: Data from sixty-six patients who underwent surgery for craniopharyngioma from 2009 to 2013 in Denmark were reviewed. Primary outcomes were visual acuity (VA) and visual field (VF) defects from pre-and postoperative visits. Secondary outcomes were optic nerve atrophy (OA) and papilledema. RESULTS: Fifty-eight patients were included. The VA of the patients 1-year after surgery improved by -0.16 log(MAR) (95%CI: -0.30 to -0.02; p = 0.0266). Visual field (VF) defects worsened in 17 eyes (30%), remained stable in 21 eyes (37%) and improved in 19 eyes (33%). The presence of papilledema and the absence of OA were significantly correlated with an improvement in VA postoperatively (p = 0.011 and p = 0.011, respectively). Patients undergoing surgery within a week or less after their first ophthalmological examination had a significant improvement in VA (-0.36; 95%CI: -0.62 to -0.09; p = 0.0099). Patients undergoing surgery using a subfrontal approach also showed improvement in VA (p = 0.048). Tumour recurrence had a significantly worse VA outcome (p = 0.0074). CONCLUSION: Patients show a slight improvement in VA 1-year after operation for craniopharyngioma. The presence of papilledema and early surgical intervention is associated with a significant improvement in VA. Early involvement of a dedicated ophthalmologist is recommended to secure an early detection of a visual decline and potential tumour recurrence.

Crouzon syndrome with acanthosis nigricans (CAN) is a very rare condition with an approximate prevalence of 1 per 1 million newborns. We add the first report on prenatal 2D and 3D ultrasound findings in CAN. In addition we present the postnatal 3D CT findings. The diagnosis was confirmed by molecular testing.
RESUMO
OBJECTIVE: The aim of this study was to uncover the most effective and safe criterion to implement for retinopathy of prematurity screening in Denmark. METHODS: This retrospective national cohort study is based on data from 3 national registers. These registers provided on infants treated for retinopathy of prematurity, infants in need of treatment but missed by the present screening program, and the candidate neonates for advanced retinopathy of prematurity development A nonlinear logistic regression model was fitted to the data, and various screening criteria were evaluated. RESULTS: During the study period (2002-2006), 116 infants were treated for retinopathy of prematurity, no treatment-demanding retinopathy of prematurity infants were missed by the screening program, and 182 premature infants were candidates for developing treatment-demanding retinopathy of prematurity. Screening criteria combining gestational age at delivery and birth weight limits and new risk-based criteria were compared with regards to their effectiveness. The risk-based criteria were the most effective. Use of the 0.13% risk-based criterion to define the population to be screened resulted in the detection of all treated infants in the study period and 17.4% fewer infants to screen. The model predicted this criterion to result in 1 missed case of treatment-demanding retinopathy of prematurity every 11 years and 1 case of blindness every 18 years in Denmark. CONCLUSIONS: Screening criteria based on risk estimates of developing treatment-demanding retinopathy of prematurity are the most effective for retinopathy-of-prematurity screening. The risk-based criterion of 0.13% can safely be implemented for future retinopathy-of-prematurity screening in Denmark.

OBJECTIVE: The objective of this study was to analyze the population incidence of retinopathy of prematurity treatment in Denmark in the 10-year period from 1996 to 2005. METHODS: Patient charts of infants treated for retinopathy of prematurity and the national birth registry provide information about neonatal parameters. These parameters, along with birth in the latter half of the period (2001-2005), were analyzed as risk factors for retinopathy of prematurity. The national registry for blind and visually impaired children was accessed to obtain information about visual impairment attributable to retinopathy of prematurity in both treated and untreated infants. RESULTS: The study population consisted of 5467 Danish preterm infants born in 1996 to 2005, with a gestational age of < 32 weeks, who survived for > or = 5 postnatal weeks; 2616 were born in 1996 to 2000, and 2851 were born in 2001 to 2005. The incidence of treated retinopathy of prematurity cases increased significantly from 1.3% in 1996 to 2000 to 3.5% in 2001 to 2005. Significant risk factors for retinopathy of prematurity treatment were low gestational age, small for gestational age, male gender, and multiple birth. Other, yet unknown factors contributed to the increased incidence in the latter half of the period. Of the study population, 0.6% were registered as visually impaired because of retinopathy of prematurity within 2 years after birth (early-detected visual impairment). The incidences were not significantly different between 1996 to 2000 and 2001 to 2005. Of all of the early-detected, visually impaired children, 16% had not been treated for retinopathy of prematurity and were considered screening failures. CONCLUSIONS: The incidence of retinopathy of prematurity treatment in Denmark has more than doubled during the past half-decade. This increase could not be fully explained by increased survival rates for the infants or by changes in the investigated neonatal risk factors.

INTRODUCTION: To present our experience with anti-TNFalpha treatment of juvenile idiopatic arthritis (JIA) associated uveitis. MATERIALS AND METHODS: All 11 children with severe uveitis were monitored between 2001 and 2005. Nine of the children had JIA and a set of twins had a rare hereditary granulomatous disease, Blau's syndrome. The patients were selected and the reason for starting anti-TNFalpha treatment was an insufficient response in the arthritis or uveitis to previous therapy. RESULTS: In all patients the anti-TNFalpha treatment reduced the activity of uveitis. The response to treatment was related to 1) visual acuity and 2) the reduction of systemic immune-suppressing agents. All 11 children are still on anti-TNFalpha treatment. CONCLUSION: Anti-TNFalpha was effective in treating uveitis in all 11 patients. In patients with active uveitis associated JIA not responding to corticosteroids and methotrexate and with declined vision the trend is to start anti-TNFalpha treatment early in the inflammatory disease to prevent long term complications to the eyes. The results indicate a superiority of infliximab over Eternacept in the treatment of uveitis.
