Persistent fetal vasculature is a spectrum of ocular abnormalities linked to an incomplete regression of the fetal ocular vasculature. A 21-years old male patient came to the outpatient clinic reporting low vision and strabismus in his left eye since 3 years of age. Ophtalmological examination revealed a normal right eye, while the left eye had a best corrected visual acuity of hand-motion perception, a 30 prism diopters esotropia, a "coralliform" cataract and a vitreous stalk joining the posterior face of the lens and the optic nerve...

BACKGROUND: Cerebral small vessel disease (CSVD) attaches people's attention in recent years. In this study, we aim to explore retinal structure and vessel density changes in CSVD patients. METHODS: We collected information on retinal metrics assessed by optical coherence tomography (OCT) and OCT angiography and CSVD characters. Logistic and liner regression was used to analyze the relationship between retinal metrics and CSVD. RESULTS: Vessel density of superficial retinal capillary plexus (SRCP), foveal density- 300 length (FD-300), radial peripapillary capillary (RPC) and thickness of retina were significantly lower in CSVD patients, the difference only existed in the thickness of retina after adjusted relevant risk factors (OR (95% CI): 0...

Lymphedema distichiasis syndrome is one of the most frequent phenotypes of primary lymphedema, even so, its prevalence is still low. This syndrome courses with the appearance of abnormal eyelashes and distichiasis during childhood or puberty. This can cause a notable discomfort on our patients, especially at such an early age. The clinic evaluation of this signs must make us have in mind this group of syndromes, because in the case of lymphedema distichiasis syndrome, we can certainly diagnose it with the genetic analysis of the FOXC2 gen on patient's serum...

In this current case series, all Coronavirus disease 2019 patients had predominant ophthalmological presentation. Only one patient sough care for concomitant respiratory symptoms. We reported herein 2 cases with cranial oculomotor nerve palsy, one patient with confirmed diagnosis of branch retinal vein occlusion, and the last one patient presenting for acute kareto-conjunctivitis with several recurrences, which was unsuccessfully treated with steroids and requiring cliclosporin. These case series highlights the importance of collecting a careful history of ocular presentation, including exposures to possible infected patients with SARS-CoV-2...

Neisseria meningitidis represents an uncommon pathogen of acute bacterial conjunctivitis. In this brief report we describe a case of meningococcal conjunctivitis in an immunocompetent adult male, with a review of the literature. The patient went to the outpatient ophtalmology clinic complaining ofsevere ocular discomfort, burning and redness for more than 2 weeks and, at slit lamp examination, he was diagnosed with a mild conjunctivitis. Microbiology cultures of ocular swabs revealed the growth of colonies, as pure culture, identified as N...

OBJECTIVES: The objective of this study was to develop a numerical model of the eyeball and orbit to simulate a blunt injury to the eyeball leading to its rupture, as well as to conduct a comparative analysis of the results obtained using the finite element method against the clinical material concerning patients who had suffered an eyeball rupture due to a blunt force trauma. MATERIAL AND METHODS: Using available sclera biometric and strength data, a numerical model of the eyeball, the orbital contents, and the bony walls were developed from the ground up...

A case of hydrocephalus is presented in a 13-year-old female with transient loss of vision from 1 week and papilledema, previous ophtalmological history was negative. Visual field was performed, and neurogical examination proved to be hydrocephalus. In literature few cases of Papilledema in adolescent children with hydrocephalus has been reported. The aim of this case report is to decode the signs, symptoms and factors associated with papilledema in children with hydrocephalus at an early stage in order to prevent a poor visual-functional residual (permanent low vision)...

Objective: To analyze the clinical features of patients with sarcoid uveitis. Methods: This was a retrospective case series study. The medical records of 19 086 patients with uveitis admitted to the Department of Ophtalmology, The First Affiliated Hospital of Chongqing Medical University from April 2008 to December 2019 were collected. The general data, medical history, treatment, diagnosis, follow-up, ophthalmic and other auxiliary examinations were retrospectively analyzed. The paired sample Wilcoxon signed rank test was used to compare the best corrected visual acuity (BCVA) of the affected eye at the first visit to the BCVA of the affected eye at the corresponding last visit...

BACKGROUND: The tumor invasion of the skull base structures is very frequent in spheno-orbital meningiomas. The aim of the present study is to evaluate the invasion rate of skull base structures and the best surgical approach and management. METHODS: The surgical series of 80 spheno-orbital meningiomas was reviewed. The tumors were classified according to the intraorbital location with respect to the optic nerve axes into three types: I-lateral: II-medial; III-diffuse...

In multiple sclerosis, remyelination trials have yet to deliver success like that achieved for relapse rates with disease course modifying treatment trials. The challenge is to have a clinical, functional outcome measure. Currently, there are none that have been validated, other than visual evoked potentials in optic neuritis. Like vision, quick eye movements (saccades) are heavily dependent on myelination. We proposed that it is possible to extrapolate from demyelination of the medial longitudinal fasciculus in the brainstem to quantitative assessment of cortical networks governing saccadic eye movements in multiple sclerosis...

Immune checkpoint inhibitors are now an integral part of the anti-cancer therapeutic arsenal. They have revolutionized the prognosis of certain cancers at the cost of a specific spectrum of dysimmune side effects that can affect the ophthalmological sphere. Patient education associated with increased vigilance of health care providers will allow faster detection and therefore optimal care to limit morbidity, maintain the best possible visual acuity and above all to be able to continue therapy prolonging survival...

The present case report focuses on an immunocompromised 81-year-old patient initially diagnosed with Waldenström's disease. The patient experienced a gradual vision loss and jaw pain with high erythrocyte sedimentation rate. We first suspected giant cell arteritis, despite inconclusive assessment, including a negative temporal artery biopsy. We rapidly started a corticosteroid pulse therapy followed by high-dose corticosteroid therapy that was followed even after discharge from the hospital. The patient was readmitted 20 days later with severe left retro-orbital pain and progressive left vision loss...

We describe the case of tertiary syphilis involving the skin. The lesions had a nodular-ulcerative form, localized on both arms. The patient had high titers of treponemal and non-treponemal serological tests for syphilis and histopathological picture was indicative for nodulo-ulcerative syphilis. No cardiological, neurological or ophtalmological abnormalities were found. The patient was treated with 2.4 million units i.m. of benzathine benzylpenicillin three times at weekly intervals, according to European Guideline...

The complex physiological and pathological conditions form barriers against efficient drug delivery. Cell penetrating peptides (CPPs), a class of short peptides which translocate drugs across cell membranes with various mechanisms, provide feasible solutions for efficient delivery of biologically active agents to circumvent biological barriers. After years of development, the function of CPPs is beyond cell penetrating. Multifunctional CPPs with bioactivity or active targeting capacity have been designed and successfully utilized in delivery of various cargoes against tumor, myocardial ischemia, ocular posterior segment disorders, etc...

Atopic dermatitis (AD) is a chronic, inflammatory skin disorder that most frequently occurs in children, but it can also affect adults. Even though most AD cases can be managed with topical treatments, moderate-to-severe forms require systemic therapies. Dupilumab is the first human monoclonal antibody approved for the treatment of AD. Its action is through IL-4 receptor alpha subunit inhibition, thus blocking IL-4 and IL-13 signaling pathways. It has been shown to be an effective, well-tolerated therapy for AD, as well as for asthma, chronic rhinosinusitis with nasal polyposis (CRSwNP), and eosinophilic esophagitis (EoE)...

BACKGROUND: In the literature, most of the studies on Charles Bonnet Syndrome (CBS) were performed on older populations. This study aims to determine the prevalence and epidemiology of CBS and the nature of the hallucinations of the younger group of patients from an ophthalmology outpatient clinic of a university hospital. SUBJECTS AND METHODS: Twenty-eight patients were randomly chosen from the outpatient ophthalmology clinic of a university hospital, and those who agreed to participate in the study were included...

INTRODUCTION: Acute rhinosinusitis accounts for most of the cases of orbital infections and is the most common cause of periorbital oedema in children. Up to 10% of patients with orbital complications of acute rhinosinusitis may experience vision loss and other complications such as meningitis, intracranial abscess or even death. Therefore, these patients require prompt diagnosis and proper treatment. OBJECTIVES: This study aims to report the clinical presentation and management of post-septal orbital complications of acute rhinosinusitis in the paediatric population...

INTRODUCTION: Dacryops is a rare benign cystic lesion of the lacrimal gland often developing in the palpebral gland. The exact etiology of dacryops remains unclear. Diagnosis could be suspected clinically and established histopathologically. Treatment is commonly surgical. PRESENTATION OF CASE: We report the case of a 75-year-old woman with past history of total conservative parotidectomy for a benign tumor 10 years ago. She presented to the Ophtalmology Department at Farhat Hached University Hospital of Sousse with a painful swelling of the left supero-external orbital angle...

In most cases, vestibular schwannomas with papilledema are associated with intracranial hypertension secondary to hydrocephalus (obstructive or communicating). We describe the atypical case of a 39-years-old man who presented with bilateral papilledema revealing a vestibular schwannoma, but without hydrocephalus and with normal intracranial pressure. Ophtalmologic signs were completely resolved after tumor removal. The pathophysiological mechanism generally described to explain bilateral papilledema in such cases is tumor-induced hyperproteinorachia...
