Vascular alterations revealed with optical coherence tomography angiography in patients with choroideremia
Conclusion: Choroideremia is a disease in which the choriocapillaris maintains a normal structure until the loss of the overlying retinal pigment epithelium. The inner retina also appears not to be affected at the vascular level. Although this study is limited by the small number of patients eligible for inclusion in the study, the observations support the concept of targeting gene therapy to the retinal pigment epithelium and outer retina because there is no evidence of independent degeneration of the choriocapillaris.
Conclusion: A PPS development was observed in initially non-myopic patients of a family with unusually severe dominant RP. The PPS concerned only the area with relatively preserved outer retinal layers (outer nuclear layer and ellipsoid zone). How the outer retina could guide choroid and scleral remodelling remains unclear. PMID: 31438752 [PubMed - as supplied by publisher]

Graphene promises to transform the way doctors treat and prevent many major illnesses. From eye implants that combat blindness to dental fillings, graphene has the potential to revolutionise medicine.
Authors: Tao D, Ni N, Zhang T, Li C, Sun Q, Wang L, Mei Y Abstract The major ophthalmic complication in patients with diabetes is diabetic retinopathy (DR), which is one of the major eye diseases that causes blindness. It is well established that the occurrence and duration of DR is positively correlated with duration of diabetes. Advanced glycation end product (AGE) accumulation in patients with diabetes is one factor that leads to the development of DR. However, the underlying mechanisms remain unclear. In the present study, the role of phosphoinositide 3‑kinase/protein kinase B (Akt) signaling in AGE‑induced...
Conclusion: Anterior uveitis was the most common pattern found among uveitis patients. Herpes simplex and toxoplasmic chorioretinitis were the most common-identified infectious causes. PMID: 31429610 [PubMed - as supplied by publisher]
Cataract is the most common cause of blindness worldwide. We investigated the association between cataract and cotinine-verified smoking status, which includes “hidden” smokers.
ConclusionsThe study reveals a dynamic development of the eye bank over the last 30 years and emphasizes the importance of an active quality management in coping with the challenges of modern eye banking. The increasing trend of cornea collection and transplantation is a reflection of the needs and efforts towards treating and eliminating corneal blindness.
Conclusion: The Government of Ghana should revitalize the goals of VISION 2020 beyond the year 2020 and spearhead a concerted effort to ensure equitable distribution of human and infrastructural resources across the country. PMID: 31428165 [PubMed - in process]
Scientists in Taiwan found long-term exposure to nitrogen dioxide - a pollutant that is especially linked to old diesel cars - increased the risk of AMD among over-50s by 91 per cent.
Abstract The goal of this work is to provide evidence for the cognitive objectification of sexualized targets via a change blindness paradigm. Since sexual objectification involves a fragmented perception of the target in which individuating features (i.e., the face) have less information potential than sexualized features (i.e., body parts), we hypothesized that changes in faces of sexualized targets would be detected with less accuracy than changes in faces of nonsexualized targets. Conversely, we expected that changes in body parts would be detected with higher accuracy for sexualized than nonsexualized targets...
