Purpose: The purpose of this study was to report a case of a Filipino woman with a history of breast cancer who presented with unilateral choroidal infiltration, which led to the diagnosis of sarcoidosis.
Methods: Case report and literature review.
Results: A 64-year-old Filipino woman with a history of breast cancer presented with unilateral choroidal nodules. Her blood tests were negative for common causes of choroidal infiltration (angiotensin-converting enzyme, lysozyme, Treponema pallidum particle agglutination), and Mantoux skin test and a chest x-ray were negative. Her diagnosis could only be made by biopsy of the two hypermetabolic paratracheal nodes seen on the positron emission tomography-computed tomography.
Conclusion: Choroidal infiltration may be the presenting feature of sarcoidosis even in ethnicities known to have very low incidence of the disease. If the chest x-ray is negative and the clinical suspicion warrants it, a CT or positron emission tomography-computed tomography of the thorax may be helpful in identifying nonhilar mediastinal lymphadenopathy. As in our case, fine-needle aspiration biopsy of these nodes may lead to confirmation of the diagnosis.

Birdshot chorioretinopathy (BSCR) is a bilateral, chronic posterior uveitis with characteristic clinical and imaging findings. Multimodal imaging including optical coherence tomography, fluorescein, and indocyanine green angiography is useful in diagnosis, as well as monitoring disease activity. Cystoid macular edema, choroidal thickening and infiltration, ellipsoid loss, and vasculitis are important imaging markers for disease activity.

Choroidal nevus is the most common intraocular tumor, and most cases are benign and have no symptoms. However, choroidal nevus carries a low risk for transformation into melanoma, which is a highly aggressive and deadly cancer. In this case report, we present a male patient with blurred vision in his left eye for six months.

Choroid neovascularization (CNV) is a distinct type of age-related macular degeneration (AMD) with a poor prognosis and responsible for the majority of vision loss in the elderly population. The laser-induced CNV model is a well-established animal model frequently used to study CNV. In this study, we performed an integrated analysis of metabolomic and transcriptomic data from CNV samples, utilizing multiple approaches including single-sample gene set enrichment analysis (ssGSEA), correlation analysis, and weighted gene co-expression network analysis (WGCNA), alongside various bioinformatics platforms, to identify key metabolic and immune signatures and to investigate their interplay during angiogenesis.

Semliki Forest virus (SFV) is a neuropathogenic alphavirus which is of interest both as a model neurotropic alphavirus and as an oncolytic virus with proven potency in preclinical cancer models. In laboratory mice, peripherally administered SFV infiltrates the central nervous system (CNS) and causes encephalitis of varying severity. The route of SFV CNS entrance is poorly understood but has been considered to occur through the blood-brain barrier.

Purpose: To present a distinctive case of primary choroidal lymphoma diagnosed by choroidal biopsy with MYD88 testing.
Methods: We describe the case of a 55-year-old male with unilateral progressive blurry vision. Fundus examination found a whitish/yellowish infiltrative lesion in the posterior pole with macular edema, which had interval improvement with oral prednisone, followed by worsening on OCT with persistent subretinal hyper-reflective materials.
