Sea-fan retinal neovascularization associated with rickettsial retinitis: a case report.

Background: Rickettsial disease has been commonly associated with retinitis, retinal vasculitis, and optic nerve involvement, but the development of retinal neovascularization has been very rarely reported. We herein describe a case of rickettsial retinitis complicated with the development of sea-fan retinal neovascularization documented with multimodal imaging, including fundus photography, SS-OCT, fluorescein angiography, and SS-OCT angiography.

Case Presentation: A 26-year-old female with a history of fever one week earlier presented with sudden decreased vision in the left eye.

Rickettsial disease: An underestimated cause of posterior uveitis.

Rickettsioses are worldwide distributed infectious disease caused by intracellular small Gram-negative bacteria transmitted to humans by the bite of contaminated arthropods, such as ticks. Systemic disease typically consists of a triad of high fever, headache, and skin rash. It usually has a self-limited course, but severe, life-threatening complications can sometimes occur.

Purpose: To compare clinical profile and visual outcomes of occlusive versus non-occlusive retinal vasculitis (RV).

Methods: A retrospective comparative study.

Results: 284 patients were enrolled, including 124 patients with occlusive RV (ORV) and 160 patients with non-occlusive RV (NORV).

[Eye and Behçet's disease].

Behçet's disease is a chronic multisystem disorder characterized by relapsing inflammation for which the underlying histopathology is an occlusive vasculitis. The disease has a high prevalence in the Mediterranean region, Far and Middle Eastern countries. It is clinically characterized by oral and genital ulcerations, ocular inflammatory involvement, skin lesions, vascular involvement and numerous other systemic manifestations.

Swept source-OCT and swept source-OCT angiography findings in posterior microphthalmos.

Purpose: To describe swept source-OCT (SS-OCT) and swept source-OCT angiography (SS-OCTA) findings in eyes with posterior microphthalmos (PM).

Methods: Twelve eyes (six patients) with PM were evaluated using SS-OCT and SS-OCTA. Structural changes, subfoveal choroidal thickness (SFCT), and perifoveal capillary changes with qualitative and quantitative assessments were analyzed.

Acute multifocal retinitis: a retrospective review of 35 cases.

Background: Acute multifocal retinitis is a rare condition that has been considered to be often idiopathic. The purpose of this study was to analyze clinical features and causes of acute multifocal retinitis.

Results: This study is a retrospective review of the charts of 35 patients with acute multifocal retinitis.

[Idiopathic orbital inflammatory syndrome: Report of 24 cases].

Background: Idiopathic orbital inflammatory syndrome (IOIS) is an inflammatory condition of unknown etiology. The inflammation may affect all the structures within the orbit (anterior, diffuse, apical, myositic, dacryoadenitis) and corresponds to uniquely orbital inflammation without an identifiable local cause or systemic disease. The goal of this study is to describe the clinical and radiographic characteristics of IOIS and discuss the role of orbital biopsy in this condition.

Swept-Source Optical Coherence Tomography Angiography in West Nile Virus Chorioretinitis and Associated Occlusive Retinal Vasculitis.

A 65-year-old man with diabetes and a history of fever of unknown origin 2 weeks earlier complained of sudden decreased vision in the left eye. The patient was diagnosed with bilateral West Nile virus (WNV) chorioretinitis associated with occlusive retinal vasculitis in the left eye. Swept-source optical coherence tomography angiography (SS-OCTA) of the left eye showed extensive, well-delineated, hypointense non-perfusion areas and perifoveal capillary arcade disruption in the superficial capillary plexus, as well as larger non-perfusion areas, capillary rarefaction, and diffuse capillary network attenuation and disorganization in the deep capillary plexus.

SWEPT-SOURCE OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY IN RICKETTSIAL RETINITIS.

Purpose: To report optical coherence tomography angiography findings in a patient with rickettsial retinitis.

Methods: A 29-year-old man complaining of acute blurring vision in the right eye associated with Rickettsia conorii infection underwent a comprehensive ocular examination, fluorescein angiography, spectral-domain optical coherence tomography, and swept-source optical coherence tomography angiography.

Results: Funduscopy showed two large areas of retinitis in the inferior macula along the distribution of the inferotemporal artery with associated retinal hemorrhages, retinal edema, and serous retinal detachment.

Multimodal imaging in a case of bilateral outer retinitis associated with mumps infection.
