Purpose: To describe a case of bilateral retinitis in a patient with endocarditis and a serologically confirmed Q fever.

Methods: A single case report documented with multimodal imaging.

Results: A 55-year-old patient with culture-negative endocarditis was referred to our department for an ocular examination.

A Case of Infantile Cataract and Neonatal Hypoglycemia.

Purpose: To describe a case of lamellar cataract in a child with a history of neonatal hypoglycemia and illustrate the importance of meticulous history-taking in children with cataracts, especially before planning surgery.

Methods: A single case report.

Results: A 7-year-old girl with a history of neonatal hypoglycemia and ketoacidosis with high suspicion of a primary defect in ketone body utilization who presented with bilateral progressive blurred vision.

Introduction: There are three types of primary hyperoxaluria, with type 1 considered the most severe.

Aim: To analyze the clinical, genetic, and evolutionary characteristics of type 1 primary hyperoxaluria with pediatric onset.

Methods: This was a retrospective, descriptive study that included Tunisian children under the age of 18 at the time of diagnosis over a period of 25 years (January 1, 1996, to December 31, 2022).

Attitudes of ophthalmologists towards pharmaceutical promotion.

Introduction: The interaction between physicians and pharmaceutical industry highlighted many issues lately concerning their influence on physician's attitude and their prescribing behavior.

Aim: To evaluate the attitudes of Tunisian ophthalmologist towards pharmaceutical promotion.

Methods: Data was collected through an auto-administered anonymous questionnaire elaborated in French that was distributed to 160 ophthalmologists (residents and specialists) working in hospitals or private practices in four Tunisian governorates (Tunis, Sousse, Monastir and Sfax).

Clinical features of infectious uveitis in a Tunisian population.

Introduction: Infectious uveitis (IU), one of the main causes of ocular inflammation in Tunisia, has various etiologies and clinical presentations.

Aim: To report the causes and clinical features of IU in a Tunisian population.

Methods: Patients with IU referred to our department from February 2019 to January 2022 were included in a retrospective observational study.

Peripheral retinal cysts in presumed ocular toxocariasis.

Typical clinical manifestations of ocular toxocariasis are central posterior granuloma, peripheral granuloma and chronic endophthalmitis. Herein we report the presence of peripheral subretinal cysts in two cases with a presumed ocular toxocariasis (OT).

Neuro-Ophthalmological Manifestations of Horner's Syndrome: Current Perspectives.

Horner's syndrome (HS) is caused by a damage to the oculosympathetic pathway. HS may be congenital, but it is usually acquired and may reveal a life-threatening condition. According to the anatomic location of the underlying pathologic process, HS is classified as central, pre- or postganglionic, when the lesion affects the first, second or third-order neuron, respectively.

Surgical management of lifebuoy cataract.

Lifebuoy cataract is a rare form of congenital cataract with anatomical characteristics. Herein, we present a case of an otherwise healthy 42-year-old female with a long-standing history of blurred vision. Examination showed the presence of esotropia and bilateral horizontal nystagmus.

Unusual cause of cerebral calcifications in an 8-year-old girl.

Key Clinical Message: Genetic counseling and genetic screening for hyperoxaluria should be recommended for children with urinary lithiasis for early management to avoid progression to oxalosis especially if there is a family history of lithiasis.

Unlabelled: Primary hyperoxaluria type 1 (PH1) is caused by a deficiency of the liver peroxisomal enzyme alanine-glyoxylate aminotransferase (AGT) resulting in overproduction of calcium oxalates. In its later stage, a systemic deposit of calcium oxalates is observed.

A novel variant associated with severe diabetic retinopathy in Wolfram syndrome type 1.

Background: Wolfram syndrome type 1 is a rare neurodegenerative disorder including diabetes insipidus, diabetes mellitus, optic atrophy, and deafness, with variable additional findings. The phenotypic spectrum is very heterogeneous, with non-autoimmune juvenile-onset diabetes and optic atrophy as minimal criteria for the diagnosis. Biallelic mutations in the gene are the causative genetic anomaly for the syndrome, with, however, no evident genotype-phenotype correlation.

Acute Painful Horner's Syndrome Revealing Eagle's Syndrome: A Report of Two Cases.

Eagle's syndrome (ES) is characterised by an abnormally elongated styloid process. It remains a complex pathology and the ophthalmological symptoms are relatively rare. Herein, we report two cases who presented to our clinic with unilateral and painful Horner's syndrome.

Epidemiological, clinical, and therapeutic characteristics of Behçet's disease: a monocentric study in Tunisia.

Introduction: to describe the epidemiological, clinical, therapeutic and evolving characteristics of Behçet´s disease and identify prognostic factors.

Methods: we have realized a retrospective, single-center study, conducted over a period of 26 years and including 130 patients presenting Behçet´s disease and hospitalized in an Internal Medicine Department.

Results: the mean age of the Behçet´s disease at onset was 30.

Swept Source OCT in monitoring uveal effusion after trabeculectomy in a nanophtalmic eye.

Uveal effusion syndrome describes serous detachments of the choroid and ciliary body with exudative retinal detachment. It is a complication following glaucoma filtering surgeries such as trabeculectomy especially in nanophthalmic eyes. We report a rare case of a 42-year-old-woman, with nanophtalmos, who developed posterior serous retinal detachment and uveal effusions after trabeculectomy for chronic angle closure glaucoma.

Contribution of ultra-wide field fluorescein angiography in diabetic retinopathy in a Tunisian population.

Aim: To assess the contribution of ultra-wide field (UWF) fluorescein angiography (FA) in clinically non proliferative diabetic retinopathy (DR) and to study the relationship between peripheral vascular lesions and the presence of diabetic macular edema (DME).

Methods: Retrospective study of consecutive UWF-FA obtained using a wide-field contact lens system. DME was detected on both FA and spectral-domain optical coherence tomography (SD-OCT).
