Superior ophthalmic vein thrombosis in unique double origin: a case report.

Superior ophthalmic vein thrombosis (SOVT) is a rare orbital pathology. It can cause serious complications if it isn´t diagnosed appropriately. It can be secondary to many etiologies, septic or aseptic ones.

Atypical Presentation Revealing Sorsby Macular Dystrophy: A Case Report.

Sorsby macular dystrophy is an autosomal dominant disorder secondary to heterozygous mutations in the TIMP3 gene in 22q12. It begins with fine, pale, drusen-like deposits or confluent, faint yellow material or sheets beneath the retinal pigment epithelium, but it eventually progresses to either geographic atrophy with pigmentary clumps or scars due to the choroidal neovascular membrane around the fourth decade of life. We describe a patient who presented with a progressive loss of unilateral visual acuity, wrongly suggesting an infectious or inflammatory disease.

[Usher syndrome: about a case].

Usher syndrome is a genetic disease resulting in double sensory deprivation (auditory and visual) called deafblindness. We report the case of a 50-year old patient, born to consanguineous parents, presenting with congenital deafness associated with normal vestibular function and pigmentary retinopathy responsible for decreased bilateral visual acuity occurred at the age of 16 years. This association composes Usher syndrome type 2, a rare autosomal recessive disorder.

[Role of oral antiviral therapy in the treatment of acute retinal necrosis].

Unlabelled: Acute retinal necrosis syndrome (ARNS) is a rare but devastating uveitic syndrome with devastating visual outcome (visual prognosis ++). It should be diagnosed as early as possible because of its severity and its risk of bilateralization. This is a rare entity caused by the group of herpes viruses.
