Achieving Quiescence with Fluocinolone Implants.

Persistent anterior uveitis causing cystoid macular oedema may necessitate either intraocular or systemic immunosuppression. This case report highlights how a newly licenced treatment, fluocinolone acetonide (Iluvien®, Alimera Sciences Ltd., England, UK) achieves quiescence in refractory and steroid-dependent disease and in the presence of an acute relapse.

Reduced Macular Vessel Density and Capillary Perfusion in Glaucoma Detected Using OCT Angiography.

AIMS: To evaluate retinal vasculature changes in primary open-angle glaucoma (POAG) and whether the functional visual loss correlates with parameters obtained using optical coherence tomography angiography (OCTA). MATERIALS AND METHODS: OCT and OCTA images were collected from 116 POAG eyes and 40 normal eyes in a prospective, cross-sectional observational study. Glaucomatous eyes were further divided into three groups according to a Glaucoma Staging System. Measurements of macular vessel density, ganglion cell complex (GCC), and disk retinal nerve fiber layer (RNFL) thickness were compared among groups. RESULTS: The macular vessel density, GCC, and RNFL are significantly reduced in POAG compared to normal eyes that also corresponds to the severity of glaucoma (Kruskal-Wallis test with Dunnett's correction; p < 0.0001). Visual field mean deviation correlates significantly with macular vessel density (p = 0.0028, r = 0.3), GCC (p < 0.0001, r = 0.6), and RNFL (p = 0.008, r = 0.36) in POAG. There are significant correlations between GCC and RNFL (p < 0.0001, r = 0.76) as well as macular vessel density (p < 0.0001, r = 0.48). Increased age also correlates with reduced macular vessel density in both normal (p = 0.0002, r = 0.49) and glaucomatous eyes (p < 0.0001, r = 0.48), but a greater proportionate reduction of vessel density is seen in glaucomatous eyes. CONCLUSION: Reduced macular vessel density occurs in POAG despite of age-related changes, which also correlates with reductions in RNFL and GCC measurements. OCTA can detect microstructural defects and offers potential to facilitate diagnosis of glaucoma.

Social media use by patients with glaucoma: what can we learn?

PURPOSE: Much health-related information is available on the internet but its quality is known to be variable. This research aimed to analyse the ophthalmic content of social media platforms which has yet to be formally assessed. METHODS: Five online social media platforms were selected, the International Glaucoma Association (IGA) forum, Facebook, Twitter, YouTube and Patient Opinion.org.uk. A total of 3785 items were scraped from the sites, collated and analysed using simple thematic analysis by two coders. RESULTS: Fourteen themes were identified. The most commonly discussed topics included treatments, care experiences, promotions and support. Un-moderated sites contain more misleading information. Complementary therapies and treatments with a poor evidence base are presented more positively than established, evidence-based treatments. CONCLUSION: Online forums give patients a space to air questions, grievances, suggestions and to provide mutual support. The information they contain may be of use to physicians by flagging adverse drug reactions, areas for service improvement or topics about which patients require more information. There is a risk of exposure to misleading content which is heightened in un-moderated sites. Social media platforms may be an adjunct to current care models by providing a supportive and educational online community if these risks are understood.
