GOOD VISUAL OUTCOME IN A BILATERAL MULTIFOCAL SYPHILITIC CHORIORETINITIS, DESPITE LATE DIAGNOSIS.

Purpose: To report a case of a good visual outcome in a patient with bilateral multifocal syphilitic chorioretinitis, despite the late diagnosis.

Methods: Ophthalmologic examination, multimodal imaging, including fundus photography, angiography, and optical coherence tomography.

Results: The authors describe a 47-year-old heterosexual man with a bilateral multifocal syphilitic chorioretinitis that was lately diagnosed and despite that had a good visual outcome.

Choroidal metastasis as the first sign of bronchioloalveolar lung cancer: case report.

Metastatic tumors are the most common intraocular malignances and choroid is by far the most common site. Breast and lung cancer are the first cause in women and men respectively. We report the case of a 71-year old woman who had choroidal tumor in her left eye.

Optic neuropathy secondary to cat scratch disease: case report.

Optic neuropathy due to cat scratch disease is a relatively infrequent occurrence associated with macular star formation and is characterized by sudden painless loss of vision mostly unilateral. Bartonella henselae is well recognized as the etiologic agent in cat scratch disease. Ocular complications of the disease occur in up to 10% of patients and include neuroretinitis.

[Bilateral optic neuritis after dengue viral infection: case report].

Dengue fever is a well known viral infection transmitted through the bite of an infected Aedes aegypti and Aedes albopictus mosquito. Its geographic distribution covers over 100 countries. Clinical presentation is variable and depends upon the age and immunological status of the patient.

'Cherry red spot' in a patient with Tay-Sachs disease: case report.

Tay-Sachs disease is an autosomal recessive disorder of sphingolipid metabolism, caused by enzyme hexosaminidase A deficiency that leads to an accumulation of GM2 in neurocytes which results in progressive loss of neurological function. The accumulation of lipid in retinal ganglion cells that leads to a chalk-white appearance of the fundus called 'cherry red spot' is the hallmark of Tay-Sachs disease. It is also seen in others neurometabolic diseases as well as in central retinal artery occlusion.

[Bilateral amaurosis due to cryptococcus meningoencephalitis: case report].

Cryptococcal meningitis is caused by the yeast Cryptococcus neoformans. Two varieties are recognized: var. gattii and var.

[Fundus flavimaculatus and subretinal neovascularization--case report].

Fundus flavimaculatus is a progressive, bilateral, hereditary retinal dystrophy characterized by ill-defined, yellowish, pisiform flecks at the level of the retinal pigment epithelium. Since the disease process is at level of the retinal pigment epithelium, it is not surprising that subretinal macular neovascularizations might occur. Nevertheless, they have been rarely reported as complications of the disease.

[Idiopathic polypoidal choroidal vasculopathy: its extreme aspects in one patient--case report].

To describe a case of idiopathic polypoidal choroidal vasculopathy and the role of indocyanine green angiography findings in the differential diagnosis of exudative maculopathies, particularly with age-related macular degeneration, and the extreme evolution of idiopathic polypoidal choroidal vasculopathy in one patient. A patient with vitreous hemorrhage was examined and evaluated by fluorescein and indocyanine green angiographies in the right eye and with hemorrhagic detachment of the retinal pigment epithelium in the left eye. The patient was treated by pars plana vitrectomy in the right eye which was followed by retinal detachment and vision loss.
