Macular and choroidal thickness in Down syndrome by swept-source optical coherence tomography (SS-OCT)
Arch Soc Esp Oftalmol. 2021 Mar 11:S0365-6691(21)00054-X. doi: 10.1016/j.oftal.2021.01.011. Online ahead of print.ABSTRACTDown syndrome (DS) is associated with certain structural and functional disorders in the whole visual system. The purpose was to compare retinal and choroidal thickness using swept-source optical coherence tomography (SS-OCT) in DS subjects with controls. This cross-sectional study included 100 eyes of 52 DS subjects and 78 eyes of 39 matching age and axial length controls. Our results showed that inner or outer retinal and ganglionar thickness showed no significant differences between DS and control group (p>0.05). However, retinal foveal thickness (rFT), ganglion foveal thickness (gFT) were significantly higher in DS group than in controls, whereas choroidal foveal thickness (cFT) and some choroidal quadrants of inner and outer rings were significantly lower (p

CONCLUSIONS: Neuro-ophthalmologic findings are mostly normal in patients with visual snow syndrome. Retinal or neurological diseases must be excluded as possible causes of visual snow. PMID: 33029971 [PubMed]

Abstract Objectives: Retina abnormalities are related to cognitive disorders in patients with Alzheimer's disease (AD). Retinal amyloid beta (Aβ) can be labeled by curcumin. We measured Aβ content in the cerebrum and retina of APPswe/PS1dE9 (APP) transgenic mice with early age to investigate the correlation between cerebrum and retina. Methods: APP mice and age-matched wild-type mice were investigated every month from age 2 months to 6 months to assess changes in Aβ content in the retina and cerebrum. At the beginning of each month, mice were fed a curcumin diet (50 mg/kg/day) for 7 cons...
CONCLUSION: Birdshot retinochoroidopathy can be found in Hispanic patients. Our study suggests that the characteristics upon presentation in Hispanics may be similar to those of Caucasian cohorts. PMID: 33031692 [PubMed - as supplied by publisher]

Conclusions: These findings suggest that zebrafish dscam and sdk2 paralogs were likely the result of the teleost whole genome duplication and that all CAM duplicates show some differential expression patterns. We also demonstrate that the comparative expression patterns of CAM genes in the zebrafish are distinct from the exclusive expression patterns observed in chick retina, in which retinal ganglion cells express one of the four chick Dscam or Sdk genes only. The patterns in zebrafish are more similar to those of mice, in which co-expression of Dscam and Sdk genes is observed. These findings provide the groundwork for fu...
