RESUMO
Purpose: Retinal and optic nerve diseases have become the primary cause of irreversible vision loss and blindness. However, there is still a lack of thorough evaluation regarding their prevalence in China. Methods: This artificial intelligence-based national screening study applied a previously developed deep learning algorithm, named the Retinal Artificial Intelligence Diagnosis System (RAIDS). De-identified personal medical records from January 2019 to December 2021 were extracted from 65 examination centers in 19 provinces of China. Crude prevalence and age-sex-adjusted prevalence were calculated by mapping to the standard population in the seventh national census. Results: In 2021, adjusted referral possible glaucoma (63.29, 95% confidence interval [CI] = 57.12-68.90 cases per 1000), epiretinal macular membrane (21.84, 95% CI = 15.64-29.22), age-related macular degeneration (13.93, 95% CI = 11.09-17.17), and diabetic retinopathy (11.33, 95% CI = 8.89-13.77) ranked the highest among 10 diseases. Female participants had significantly higher adjusted prevalence of pathologic myopia, yet a lower adjusted prevalence of diabetic retinopathy, referral possible glaucoma, and hypertensive retinopathy than male participants. From 2019 to 2021, the adjusted prevalence of retinal vein occlusion (0.99, 95% CI = 0.73-1.26 to 1.88, 95% CI = 1.42-2.44), macular hole (0.59, 95% CI = 0.41-0.82 to 1.12, 95% CI = 0.76-1.51), and hypertensive retinopathy (0.53, 95% CI = 0.40-0.67 to 0.77, 95% CI = 0.60-0.95) significantly increased. The prevalence of diabetic retinopathy in participants under 50 years old significant increased. Conclusions: Retinal and optic nerve diseases are an important public health concern in China. Further well-conceived epidemiological studies are required to validate the observed increased prevalence of diabetic retinopathy, hypertensive retinopathy, retinal vein occlusion, and macular hole nationwide. Translational Relevance: This artificial intelligence system can be a potential tool to monitor the prevalence of major retinal and optic nerve diseases over a wide geographic area.

INTRODUCTION: Immune checkpoint inhibitors are a class of monoclonal antibodies that are used as a mainstay of immunotherapy for multiple solid organ malignancies. With the recent increase in popularity of these agents, immune-related adverse events including optic neuropathy are becoming more frequently reported. This review aims to explore the association between immune checkpoint inhibitors and optic neuropathy through analysis of incidence, clinical features, investigations, treatment, and patient outcomes. METHOD: A systematic search of the databases PubMed/MEDLINE, Embase, and CENTRAL was performed from inception to September 2022. Data collection and risk of bias analysis was subsequently conducted in accordance with the PRISMA guidelines. RESULTS: Eleven articles fulfilled the inclusion criteria. The results showed an increased incidence of optic neuropathy among patients receiving immune checkpoint inhibitor therapy compared to the general population. Presentation with painless reduced visual acuity and optic disc swelling was most common. Investigation findings were poorly documented. The only two patients who achieved full resolution of symptoms were treated with oral prednisolone. CONCLUSION: There is a strong association between immune checkpoint inhibitor therapy and development of optic neuropathy. Although it remains uncommon, the incidence of optic neuropathy in this population exceeds that of the general population. Future research is needed to further characterise the risk profiles of patients who are most likely to develop ICI-associated optic neuropathy, and treatment pathways for these patients.

Purpose: To analyze the clinical presentations, risk factors, and management outcomes in patients presenting with dysthyroid optic neuropathy (DON). Methods: This is a retrospective, single-center study carried out on consecutive patients presenting with DON over a period of 4 years (2013-2016). The VISA classification was used at the first visit and subsequent follow-ups. The diagnosis was based on optic nerve function tests and imaging features. Demographic profiles, clinical features, risk factors, and management outcomes were analyzed. Results: Thirty-seven eyes of 26 patients diagnosed with DON were included in the study. A significant male preponderance was noted (20, 76.92%). Twenty patients (76.9%, P = 0.011) had hyperthyroidism, and 15 (57.69%, P = 0.02) were smokers. Decreased visual acuity was noted in 28 eyes (75.6%). Abnormal color vision and relative afferent pupillary defects were seen in 24 (64.86%) eyes, and visual field defects were seen in 30 (81.01%) eyes. The visual evoked potential (VEP) showed a reduced amplitude in 30 (96.77%, P = 0.001) of 31 eyes and delayed latency in 20 (64.51%, P = 0.0289) eyes. Twenty-six (70.27%) patients were treated with intravenous methyl prednisolone (IVMP) alone, whereas 11 (29.72%) needed surgical decompression. The overall best-corrected visual acuity improved by 0.2 l logMARunits. There was no statistically significant difference in outcome between medically and surgically treated groups. Four patients developed recurrent DON, and all of them were diabetics. Conclusion: Male gender, hyperthyroid state, and smoking are risk factors for developing DON. VEP, apical crowding, and optic nerve compression are sensitive indicators for diagnosing DON. Diabetics may have a more defiant course and are prone to develop recurrent DON.

PURPOSE: Prior studies on compressive optic neuropathy (CON) have come from large tertiary centers, which may contain referral bias toward more severe or atypical disease. To our knowledge, there are no studies to determine the population-based etiologies and clinical outcomes of compressive optic neuropathy (CON). This study aims to bridge that gap using the Rochester Epidemiology Project database. DESIGN: Retrospective, population-based cohort. METHODS: Medical records of all residents living in Olmsted County, Minnesota, from January 1, 2000, through December 31, 2018, were screened for CON. Demographic and clinical information were collected before and after treatment. RESULTS: Twenty-three patients had a confirmed diagnosis of CON during our study period, which provided an overall incidence of 1.14 per 100 000 per year. Average age at onset of CON was 51 years (SD 24), and 39% were male. The most common etiologies were pituitary adenoma and meningioma. There was significant improvement in visual fields (P < .003) but not in visual acuity (P = .08) after patients underwent treatment for CON. There was also a significant relationship between the time until treatment and the degree of visual field improvement at follow-up (Pearson correlation rho = -0.58, P < .047). CONCLUSION: To our knowledge, this study provides the first population-based incidence of CON. The finding that earlier treatment leads to better visual outcomes stresses the importance of having CON on the differential diagnosis of patients with optic neuropathy.

BACKGROUND: To evaluate the demographic, etiological, and clinical properties, as well as the treatment modalities of neuro-ophthalmological diseases in childhood. METHODS: We retrospectively analyzed the clinical data of patients younger than 18 years old who were referred to the Neuro-Ophthalmology Department of Ulucanlar Eye Hospital from 2004 to 2019. RESULTS: Of 1,910 patients who presented to the Neuro-Ophthalmology Department, 128 (6.7%) were younger than 18 years old at diagnosis, and their data were analyzed. The three most common diagnoses were congenital optic disc (OD) abnormalities in 43 (33.5%), optic neuropathies in 42 (32.8%), and idiopathic intracranial hypertension in 11 (8.5%) patients. The most frequent symptoms were as follows: decreased visual acuity in 36 (28.1%), headache in 32 (25%), and no symptoms in 19 (14.8%) patients. The best visual prognosis was associated with inflammatory optic neuritis, while hereditary and compressive optic neuropathy resulted in poor visual acuity outcomes. CONCLUSIONS: Congenital OD abnormalities and optic neuropathies are the most frequently seen disorders among children with neuro-ophthalmological diseases. Clinicians should also be aware that children without any symptoms may also have neuro-ophthalmological disorders.

PURPOSE: To examine the frequency of ophthalmic immune-related adverse events (OirAEs) in melanoma, other cancers, and after immune checkpoint inhibitor (ICI) treatment. DESIGN: Retrospective clinical cohort study. METHODS: This study identified patients diagnosed with OirAEs between January 1, 2011, and December 31, 2018, in the Kaiser Permanente Southern California electronic health records. The primary exposures of interest were prior initiation of ICIs and underlying cancer diagnosis. Risk-adjusted prevalence of OirAEs was evaluated in patients with melanoma, with nonmelanoma cancer, and without cancer. The 1-year incidence of OirAEs and recurrence of prior ophthalmic disease were identified in ICI-receiving patients with melanoma and nonmelanoma. RESULTS: Among 4,695,669 unique patients identified, 9.9% had a cancer diagnosis, of whom 2.8% had a diagnosis of melanoma. Overall prevalence for uveitis and selected neuro-ophthalmic diagnoses was 341.8/100,000 patient-years in patients with melanoma and 369.6/100,000 patient-years in patients with nonmelanoma cancer regardless of ICI treatment, compared with 142.2/100,000 patient-years in patients without cancer. A total of 2,911 unique patients received ICI therapy. Compared with patients with nonmelanoma cancer, patients with melanoma on any ICI had elevated 1-year incidence rates of uveitis (1.2% vs 0.2%; risk-adjusted odds ratio, 6.45). High 1-year recurrence rates for uveitis in ICI patients with a prior uveitis history were also observed. CONCLUSIONS: The prevalence of all OirAEs was substantially higher in patients with cancer, with ICI-related uveitis risk specifically increased in patients with melanoma compared with patients with nonmelanoma cancer. Evidence-based guidelines for ophthalmic monitoring of patients undergoing ICI treatment may require different risk stratifications based on underlying cancer diagnosis, specific ICI used, and prior history of uveitis.

OBJECTIVES: Neurological complications of sarcoidosis are uncommon and the natural history and optimal treatments under-researched. With the advent of biological therapies, it is important to define the clinical characteristics and immunopathology of the disease. PATIENTS AND METHODS: Patients referred to and treated within the Centre for Neurosarcoidosis over a 15 year period who had biopsy proven "highly probable" disease of the central nervous system were studied prospectively. RESULTS: Corticosteroids were used effectively in all patients, immunosuppression in 79 % and TNFα antagonists in 23 %. Treatment with steroids alone inevitably led to relapse, and low dose immunosuppression was ineffective in those with severe forms of the disease. Use of biological therapies substantially improved outcome. Patients with cranial neuropathy had an excellent outcome. Those with pachymeningitis had marked radiological abnormalities but less disablement. Those with leptomeningitis had an invasive, destructive disease which responded well to treatment but with residual neurological impairments. Treatment was required for many years, but the risk of relapse following treatment withdrawal was low. Infective complications arose in six. There were two deaths, neither directly related to the neurological disease, nor its treatment. CONCLUSIONS: This prospective study of the natural history and treatment response in neurosarcoidosis provides evidence that the use of high dose immunosuppression and early and prolonged use of biological therapies is associated with greatly improved outcomes and lower mortality. The data may be used to plan further studies and treatment trials, and provide class IV evidence for the effectiveness of biological agents in the treatment of Neurosarcoidosis.

Pseudotumour cerebri syndrome (PTCS) remains to be fully investigated in Chinese patients and our study reported PTCS-related clinical differences between Chinese patients and Western patients. This study enrolled 55 consecutive patients (females: 44, median age: 37 y, age range: 14-62 y) with PTCS diagnosed from October 2015 to December 2017. Nine (16.4%, females) patients had primary PTCS, and 46 (83.6%) had secondary PTCS (P = 0.001). At presentation, 81.8% of patients had grade >3 papilloedema, with 23.6% having diffusely constricted fields. Mean subarachnoid space around the optic nerve measured by retrobulbar ultrasonography during lumbar puncture was 1.12 ± 0.17 mm and decreased to 0.86 ± 0.11 mm after treatment. Optical coherence tomography (OCT) showed that 92.9% of eyes with intact macular ganglion cell-inner plexiform layer (GCIPL) at baseline had good outcomes after treatment. Patients' demographic and clinical characteristics showed that secondary PTCS was more common than primary idiopathic intracranial hypertension in Chinese patients. Polycystic ovarian syndrome was the main associated factor in females. Poor visual function was common at presentation. Noninvasive ocular ultrasonography and OCT are the prognostic indicators of PTCS treatment in intracranial pressure and visual function, respectively, after PTCS treatment.

OBJECTIVE: To assess the radiation-induced optic neuropathy (RION) prevalence, following high dose pencil beam scanning proton therapy (PBSPT) to skull base and head and neck (H&N) tumours. METHODS: Between 1999 and 2014, 216 adult patients, median age 47 years (range, 18-77), were treated with PBS PT for skull base or H&N malignancies, delivering ≥45 GyRBE to the optic nerve(s) (ON) and/or optic chiasma (OC). The median administered dose to the planning target volume was 74.0 GyRBE (range, 54.0-77.4). The median follow-up was 5.3 years (range, 0.8-15.9). RESULTS: RION was observed in 14 (6.5%) patients at a median time of 13.2 months (range, 4.8-42.6) following PBSPT. Most (92.9%) of RION were symptomatic. Most affected patients (11/14; 79%) developed unilateral toxicity. Grade 4, 3, 2 and 1 toxicity was observed in 10, 2, 1 and 1 patients, respectively. On univariate analyses, age (<70 vs ≥70 years; p < 0.0001), hypertension (p = 0.0007) and tumour abutting the optic apparatus (p = 0.012) were associated with RION. OC's V60 GyRBE was of border line significance (p = 0.06). None of the other evaluated OC-ON dose/volume metrics (Dmax, Dmean, V40-60) were significantly associated with this complication. CONCLUSION: These data suggest that high-dose PBS PT for skull base and H&N tumours is associated with a low prevalence of RION. Caution should be however exercised when treating elderly/hypertensive patients with tumours abutting the optic apparatus. ADVANCES IN KNOWLEDGE: This is the first study reporting the risk of developing RION following proton therapy with PBS technique, demonstrating the safety of this treatment.

BACKGROUND: To evaluate the risk of developing optic neuropathy (ON) in patient with both non-surgery and surgery-indicated chronic rhinosinusitis (CRS) via the national health insurance research database in Taiwan. METHODOLOGY/PRINCIPAL FINDINGS: 44,176 Patients with a diagnostic code of CRS was selected, which included 6,678 received functional endoscopic sinus surgery (FESS) regarded as the surgery-indicated CRS. Each individual in the study group was matched to two non-CRS patients by age and gender. The outcome was set as the occurrence of ON according to the diagnostic codes occurred after the index date. Poisson regression was used to calculate the adjusted relative risk (aRR) and conditional Cox proportional model was used to estimate the adjusted hazard ratio (aHR). There were 131 and 144 events of ON occurred in the study group and the control group respectively during the follow-up period. The whole study group, whether received FESS or not, demonstrated both significant aRR and aHR compared to the control group after adjusting demographic data, prominent ocular diseases, and systemic co-morbidities. In addition, both the aRR and aHR were higher in CRS patient received FESS than those with CRS but without FESS management. CONCLUSION: The existence of CRS, especially the surgery-indicated CRS is a significant risk factor for the following ON using multivariable analysis.

ABSTRACT Purpose: To evaluate the prevalence, clinical characteristics, and types of optic nerve involvement in patients with ocular toxoplasmosis. Methods: For this retrospective cross-sectional study, we examined all patients with active ocular toxoplasmosis referred to our Uveitis Section during the last 12 years, and we included patients with optic nerve involvement in the study. The primary outcome was the prevalence of optic nerve involvement, and secondary outcomes included the types of optic nerve involvement and the final best-corrected visual acuity after treatment. Results: The prevalence of optic nerve involvement was 14.4%, with the leading cause being the activation of a juxtapapillary lesion (70.5%). We found papillitis in two eyes and neuroretinitis in two eyes (11.7% for each). We only detected one optic nerve involvement secondary to a distant active lesion (5.8%). Sixteen patients (94.1%) had unilateral ocular toxoplasmosis. The overall final best-corrected visual acuity after treatment was 10/10 (LogMAR = 0.0) excluding the three patients with a juxtapapillary scar involving the macula. Conclusions: Optic nerve involvement was common in patients with ocular toxoplasmosis. The main type of optic nerve involvement was caused by activation of an old juxtapapillary lesion. Treatment was quickly effective, but the best-corrected visual acuity was dependent on the presence of a scar in the papillomacular bundle.
RESUMO Objetivos: Avaliar a prevalência, características clínicas e tipos de acometimento do nervo óptico em pacientes com toxoplasmose ocular. Métodos: Para este estudo retrospectivo transversal, examinamos todos os pacientes com toxoplasmose ocular ativa encaminhados ao nosso Setor de Uveíte nos últimos 12 anos, e incluímos pacientes com comprometimento do nervo óptico no estudo. O resultado primário foi a prevalência do envolvimento do nervo óptico, e os resultados secundários incluíram os tipos de envolvimento do nervo óptico e a acuidade visual final melhor corrigida após o tratamento. Resultados: A prevalência de acometimento do nervo óptico foi 14,4%, sendo a principal causa a ativação de uma lesão justapapilar (70,5%). Encontramos papilite em dois olhos e neuroretinite em dois olhos (11,7% para cada um). Apenas detectamos um comprometimento do nervo óptico secundário a uma lesão ativa distante (5,8%). Dezesseis pacientes (94,1%) apresentavam toxoplasmose ocular unilateral. A acuidade visual final com melhor correção após o tratamento foi 10/10 (LogMAR= 0,0) excluindo os três pacientes com uma cicatriz justapapilar envolvendo a mácula. Conclusões: O comprometimento do nervo óptico foi comum em pacientes com toxoplasmose ocular. O principal tipo de comprometimento do nervo óptico foi causado pela ativação de uma lesão justapapilar antiga. O tratamento foi rapidamente eficaz, mas a acuidade visual final com melhor correção foi dependente da presença de uma cicatriz no feixe papilomacular.

Paraneoplastic syndromes involving the visual system are a heterogeneous group of disorders occurring in the setting of systemic malignancy. They are unrelated to local tumor invasion or metastasis and unexplained by nutritional, metabolic, infectious or iatrogenic causes. The presence of antibodies may aid in the diagnosis of a paraneoplastic syndrome, although this is not an absolute requirement. Chorioretinal involvement is seen in CAR (cancer-associated retinopathy) syndrome, MAR (melanoma-associated retinopathy) syndrome, paraneoplastic vitelliform maculopathy, and bilateral diffuse uveal melanocytic proliferation. Paraneoplastic neurological syndromes with ophthalmologic involvement include optic neuropathy, opsoclonus-myoclonus, Eaton-Lambert myasthenic syndrome, paraneoplastic cerebellar degeneration (PCD) and rhombencephalitis.

BACKGROUND: The purpose of this study was to assess the predictive factors of optic neuropathy among patients with nasopharyngeal carcinoma (NPC). METHODS: The analysis included 16 297 patients with NPC and 65 187 controls. Each patient with NPC was randomly frequency-matched with 4 individuals without NPC by age, sex, and index year. Cox proportional hazard models were applied to measure the hazard ratios (HRs) and 95% confidence intervals (CIs) of optic neuropathy development associated with NPC. RESULTS: The risk of optic neuropathy was significantly higher in the NPC cohort (adjusted HR [aHR] 3.42; 95% CI 2.85-4.09; P < .001). Independent risk factors for optic neuropathy among patients with NPC included stroke (aHR 1.7; 95% CI 1.07-2.7; P = .03) and receipt of chemotherapy (aHR 1.55; 95% CI 1.17-2.06; P = .002). CONCLUSION: The risk of optic neuropathy was significantly higher in patients with NPC than in the general population.

PURPOSE: The purpose of the study is to assess the displacement of lamina cribrosa (LC) and prelaminar tissue area (PTA) changes following trabeculectomy and non-penetrating deep sclerectomy (NPDS) using spectral-domain optical coherence tomography (SD-OCT) with enhanced depth imaging technology. METHODS: A total of 30 patients underwent glaucoma surgery. Sixteen patients underwent trabeculectomy, and 14 patients undertook NPDS. Serial horizontal B-scan images of optic nerve head (ONH) were obtained using SD-OCT preoperatively, and at 2-week, 1-, 3-, and 6-month postoperative visit (6 pv). LC displacement magnitude and PTA changes were determined from selected B-scan images. Correspondingly, OCT retinal nerve fiber layer (RNFL) parameters were measured. RESULTS: Intraocular pressure (IOP) decreased from 27.4 ± 10.3 mmHg (mean ± standard deviation) to 10.2 ± 4.0 mmHg (P = 0.011) and from 19.9 ± 4.0 mmHg to 11.9 ± 3.6 mmHg (P = 0.012) at 6 pv, for trabeculectomy and NPDS, respectively. There was a significant decrease in the LC depth from a baseline glaucomatous LC displacement of 468.0 ± 142.4 to 397.6 ± 125.2 µm in the trabeculectomy group (P = 0.001) and from 465.2 ± 129.6 to 412.0 ± 122.4 µm in the NPDS group (P = 0.029) at 6 pv. The PTA differed between the procedures at baseline (P = 0.002), but was not statistically significant postoperatively. Multivariate analysis for all patients including age, magnitude of IOP reduction, baseline glaucomatous LC displacement, magnitude of LC displacement, and the type of surgery revealed that only the magnitude of LC displacement was associated with significant RNFL thinning on average (r2 = 0.162, P = 0.027) and in the following sectors: temporal superior (r2 = 0.197, P = 0.014), temporal (r2 = 0.150, P = 0.034), and nasal superior (r2 = 0.162, P = 0.027). CONCLUSIONS: Decrease in the LC depth after NPDS surgery can be observed at 6 pv. Regardless of the performed procedure, magnitude of LC displacement is associated with significant, focal RNFL thinning.

BACKGROUND/AIMS: The risk factors for pituitary hormone dysfunction (PHD) in children with optic nerve hypoplasia (ONH) are not well understood. This study identified the type, timing, and predictors of PHD in children with ONH. METHODS: ONH patient charts were reviewed retrospectively. The incidence rate of PHD was calculated assuming a Poisson distribution. Predictors of PHD were identified through a multivariable Cox proportional hazards model. RESULTS: Among 144 subjects with ONH, 49.3% (n = 71) developed PHD over 614.7 person-years of follow-up. The incidence was 11.55 (95% confidence interval [CI]: 9.02-14.57/100 person-years). The median time to first PHD was 2.88 (interquartile range: 0.02-18.72) months. Eighty-two percent developed their first PHD by their 5th and 90% by their 10th birthday, and 89% within 5 years of ONH diagnosis. Prematurity (adjusted hazard ratio [aHR]: 0.33; 95% CI: 0.1-1.07), blindness (aHR: 1.72; 95% CI: 1.03-2.86), maternal substance abuse (aHR: 1.51; 95% CI: 0.91-2.48), abnormal posterior pituitary (aHR: 3.8; 95% CI: 2.01-7.18), and hypoplastic/absent anterior pituitary (aHR: 2.52; 95% CI: 1.29-4.91) were significant predictors of PHD. CONCLUSIONS: The clinical predictors of PHD included blindness, pituitary gland abnormalities, and maternal substance abuse. These predictors help clinical decision-making related to the need for and frequency of hormone testing in pediatric patients with ONH.

PURPOSE: To examine the relationship between retinal detachment and retrobulbar cysts in patients with optic nerve coloboma (ONC) and Morning Glory syndrome (MGS). METHODS: Patients diagnosed with either ONC or MGS were identified through a search of the Sick Kids database. Seventy-one patients either agreed to come in for a B-scan or had an incidental orbital B-scan or magnetic resonance imaging or both. Eyes with orbital B-scan ultrasound and/or magnetic resonance imaging images were assessed independently by two ophthalmologists and a radiologist for the presence of retrobulbar cysts. Retinal detachment was identified clinically with either indirect ophthalmoscopy or from fundus photographs. RESULTS: Forty-five of 71 (63%) and 26/71 (37%) patients had ONC and MGS, respectively. Retinal detachment occurred significantly more often in eyes with MGS than with ONC (9/17 [53%] vs. 5/45 [11%], P = 0.03, respectively). Retrobulbar cysts were not detected more often in MGS than in ONC (11/45 [24%] vs. 7/26 [27%]; P = 1.0). Eyes with retrobulbar cysts were significantly more likely to be associated with retinal detachment than those without (7/18 [39%] vs. 7/53 [13%]; P = 0.04). CONCLUSION: Retinal detachment occurs more frequently in MGS than in ONC in a cohort of patients referred to a specialist children's retinal service. Eyes with retrobulbar cysts are more likely to be associated with retinal detachment.

INTRODUCTION: Neuro-ophthalmologic conditions require specialized multidisciplinary management, both medical and surgical, for patients affected by visual loss due to nervous system disease. The primary goal of this study is to define the specificity of neuro-ophthalmology within the realm of visual health. The secondary goal is to review clinical care pathways by studying the organization of management, in terms of accessibility to care and personalization of the care pathway. PATIENTS AND METHODS: A field study was carried out from February to June 2015, within the ophthalmology service of the Pitié-Salpêtrière University Medical Center in Paris. A 30-minute interview with the patient before or after his or her neuro-ophthalmology consultation was performed, to describe the clinical care pathway. The medical records of interviewed patients were also analyzed. RESULTS: Seventeen care pathways (10 women and 7 men) were reviewed. The mean age at appearance of visual involvement was 44.5 years (±8.4 years). If we exclude 3 patients over 66 years and retired, 35.71% were active, 35.71% were disabled, and 28.57% were on sick leave. Ten patients (58.82%) met the criteria for admission to long-term care. The first step had been carried out by local private practitioners. The first physician seen was the general medicine physician (59%), then the private ophthalmologist on an emergency basis (17%). On average, patients went through 8 steps during their care pathway (from 6 to 10 steps) and 14 medical departments were involved. The study showed collaboration with the other services of the University Hospital Department of Vision and Disabilities (notably with the Fondation Rothschild, the Quinze-Vingts National Ophthalmology Hospital, and the Fondation Sainte-Marie). In addition to rehabilitation services, health care professionals participating in the outpatient care of the patients included an orthoptist (11.7%), a psychologist (11.7%), and an optician specializing in low vision for visual aids. Finally, patient support groups, AFM-Téléthon (myasthenia) and the ARIBa association (visual disability) were solicited by 2 patients for their involvement. A disturbance in activities of daily living leading to disabilities with psychological repercussions was noted by a number of patients. The most frequent complaints involve mobility (29.41%) and reading (23.52%). In total, 77% of patients state that their well-being has been affected, and they are disturbed by the progression of their disease. DISCUSSION AND CONCLUSIONS: The review of the clinical care pathway of patients affected by neuro-ophthalmological conditions shows that these pathologies are, on the one hand, often poorly understood, and on the other hand complex, leading to an often significant number of steps for the patient. This also emphasizes the necessity of a care network, specialized and structured to improve the efficiency of this management. Finally, these results demonstrate the existence of a very frequent disability, which may affect all aspects of the patients' lives, highlighting the importance of rehabilitation services and individuals participating in the follow-up of these patients beyond their acute care.

OBJECTIVE: Patients with brain tumors often report having visual complaints. This may be due to increased intracranial pressure, compression/invasion of the optic pathway or diplopia. We assessed the incidence and the etiology of visual symptoms in patients with intracranial germinoma tumors (ICGTs). METHODS AND MATERIALS: We performed a blinded retrospective review of the clinical charts and the initial magnetic resonance imaging (MRI) of 28 patients with ICGT. Thirteen tumors were pineal, five suprasellar, seven bifocal, and further three involved either the optic nerve, the corpus callosum, or the brainstem. RESULTS: Twelve patients reported visual disturbances, seven of whom mainly experienced a decrease in vision. Two of those were initially managed as "retrobulbar neuritis" when endocrinologic symptoms prompted assessment by MRI. Involvement of the optic pathway was underestimated, and both relapsed. Field deficits were definitive sequelae, whereas visual acuity was sometimes regressive in the absence of optic atrophy. CONCLUSIONS: Compression or invasion of the optic pathway by germinomas is not a rare occurrence, and this possibility should not be overlooked when thickening or contrast enhancement is detected. Radiotherapy fields should be extended accordingly.

IMPORTANCE: Identifying risk factors for radiation-induced optic neuropathy (RION) could promote a more conservative approach to radiation treatment planning in vulnerable patients. BACKGROUND: This study explored possible factors beyond radiation dose associated with the development of RION after external beam radiation therapy. DESIGN: This was a retrospective case-control study conducted at a university hospital tertiary care center. PARTICIPANTS: Cases (n = 14) meeting criteria for a diagnosis of RION by neuro-ophthalmologic exam were identified from a single-centre neuro-ophthalmology database. Controls (n = 31) without RION were selected from a single-centre radiation oncology database. METHODS: Controls were matched to cases based upon maximum radiation dose to the optic apparatus. Patient characteristics and treatment parameters were interrogated by univariate analysis for attributes predisposing to RION. MAIN OUTCOME MEASURES: The primary parameter was a significant association of patient characteristics or treatment parameters with RION. RESULTS: Controlling for radiation dosage, no significant associations for alternative risk factors were identified. CONCLUSIONS AND RELEVANCE: These results support the literature suggesting that the primary risk factor for developing RION is radiation dosage and that additional patient-related and tumour-related risk factors may play only a minor role.

This study aimed to determine the prevalence and risk factors of posttraumatic stress disorder (PTSD) in 171 acute optic neuropathy (AON) patients, and to compare the findings to those previously reported on 366 rhegmatogenous retinal detachment (RRD) patients. PTSD positively screened AON patients underwent a structured psychiatric interview and a Visual Function Questionnaire (VFQ). Clinical measures were retrieved from medical records and compared between cohorts. None of the AON patients was diagnosed with PTSD, as opposed to 2.5% of RRD patients (P = 0.063). Of the AON cohort, 34% of patients were administered steroids, compared to none of the RRD patients, whereas all of the RRD patients underwent surgery, compared to none of the AON patients (P < 0.001). Clinical measures and VFQ scores were not found as risk factors for PTSD prediction. Results imply the potential role of surgery and of steroid treatment in developing PTSD in cases of ocular insults.
