Cone electroretinograms (ERGs), elicited by different color flashes under Ganzfeld conditions, were recorded from 6 patients with multiple evanescent white dot syndrome (MEWDS). All of the patients had normal color vision as determined by the Farnsworth Panel D-15 except for one who showed non-specific errors. The b-waves elicited from short wavelength sensitive (S-) cones were reduced more than the mixed long (L-) and middle (M-) wavelength sensitive cones in the affected eyes. The ratio of the S-cone b-wave amplitude of the affected eyes to that of the normal fellow eyes was significantly lower than the comparable ratio for the L- and M-cone ERG b-waves (p=0.012). The S-cone ERGs recorded from 2 patients recovered to normal levels after their symptoms abated. These ERG results indicate that the S-cone system is more impaired than the L- and M-cone systems in the acute stage of MEWDS, and the changes in the S-cones may be reversible.

Harnessing chiral optical forces facilitates numerous applications in enantioselective sorting and sensing. To date, significant challenges persist in substantiating the holistic complex theorem of these forces as experimental demonstrations employ common light waves (e.g.

The white dot syndromes are a group of phenotypically similar disorders characterized by multiple lesions at the level of the outer retina, retinal pigment epithelium, and choroid. Common white dot syndromes whose imaging modalities have been described in this article are multiple evanescent white dot syndrome, acute posterior multifocal placoid pigment epitheliopathy, acute zonal occult outer retinopathy, multifocal choroiditis and panuveitis, punctate inner choroidopathy, serpiginous choroiditis, and birdshot chorioretinopathy. The various imaging modalities help us to better understand the pathophysiology of the various entities and help in diagnosing, monitoring, and prognosticating them.

Article Synopsis
- Indocyanine green angiography (ICGA) is crucial for diagnosing and tracking choroidal inflammation, particularly choroidal vasculitis, which is often missed by doctors not using this method during posterior uveitis assessments.
- The study analyzes ICGA signs of choroidal vasculitis, highlighting two main patterns: choriocapillaritis, which shows hypofluorescent areas indicating inflammation, and stromal choroidal vasculitis, characterized by leaking hyperfluorescent vessels.
- Overall, choroidal vasculitis is commonly found in patients with inflammatory choroid issues, and understanding its ICGA features can improve diagnosis and treatment outcomes.
