Abstract
Purpose To evaluate retinal and choroidal alterations in eyes with inactive ocular sarcoidosis and to compare the findings with healthy controls. Methods This cross-sectional study included 11 patients with inactive ocular sarcoidosis (study group) and 11 healthy individuals (control group). Retinal and choroidal vascular differences were evaluated using optical coherence tomography angiography (OCTA) and enhanced depth imaging-optical coherence tomography (EDI-OCT). Results A total of 21 eyes of ocular sarcoidosis patients without active inflammation and 22 eyes of healthy controls were analyzed. The mean whole-image deep capillary plexus vessel density was significantly lower in the study group than in the control group (P = 0.03). The acircularity index values were significantly higher, and the foveal density-300 values were significantly lower in the study group than in the control group (P = 0.01, both). The flow areas of the choriocapillaris at 1-, 2-, and 3-mm radius areas were also significantly lower in the study group (all P < 0.01). The mean choroidal thickness (CT) was significantly lower in all regions between nasal and temporal at 3000 μm in the study group (all P < 0.05). The choroidal vascularity index (CVI) values were also significantly lower in the study group (P < 0.01). Conclusion Ocular sarcoidosis was associated with a reduction in CT and the CVI with a decrease in retinal vessel density and choriocapillary flow parameters. The combination of OCTA and EDI-OCT imaging may be useful in monitoring ocular sarcoidosis eyes to detect alterations in the retinal and choroidal layers.

Abstract
PURPOSE To compare imaging modalities for the choroid of the eye, and evaluate various choroidal changes in uveitides entities. METHODS A comprehensive systematic literature review was conducted looking at current imaging modalities available to assess choroid architecture and commonly used parameters available to qualify and quantify choroidal changes, before looking at specific uveitides entities with choroidal involvement which have been broadly separated into non-infectious and infectious in etiology. RESULTS We describe the various modalities currently available to evaluate the choroid of the eye such as Ultrasound B Scan, ICGA, and OCT. Choroidal changes in various ocular and systemic diseases such as Behcet's Disease, Sarcoidosis, Syphillis, Tuberculosis, and many more have been reported and published. CONCLUSION Multiple choroidal tomographic and angiotomographic findings have been demonstrated for evaluation in uveitis. These findings can manifest in multiple ocular and systemic diseases, and can be illustrated using the various imaging modalities at present. Future advancements in choroidal imaging would help to adapt these findings into parameters for clinical practice to properly evaluate these ocular and systemic diseases.

Abstract
PURPOSE OF REVIEW Sympathetic ophthalmia is a bilateral granulomatous uveitis that occurs following unilateral trauma or surgery and is sight-threatening in the contralateral eye. Despite significant potential morbidity, disease remains poorly understood. Variable presentations and clinical courses, as well as a lack of definitive diagnostic laboratory tests can complicate the diagnosis and result in delayed treatment, which can beget permanent vision loss. This review focuses on recent advances in areas of pathophysiology, classification, diagnosis and treatment. RECENT FINDINGS Sympathetic ophthalmia is thought to involve a cell-mediated immune response to retinal and uveal antigens exposed through trauma or surgery. Multiple mechanisms have been implicated, including activation of the interleukin-23/IL-17 pathway. Ongoing emphasis is placed on early disease recognition and prompt treatment with multimodal imaging. Multiple authors advocate for the routine use of optical coherence tomography (OCT) for screening and disease monitoring. Systemic steroids and steroids sparing-immunosuppressive agents remain the mainstay of treatment. SUMMARY Understanding pathophysiology may provide useful targets for drug development, as well as allow for identification of patients at risk. OCT is a useful tool in early diagnosis and management of sympathetic ophthalmia, as OCT changes may precede clinical symptoms and signs, allowing for early disease detection and better visual outcomes.
