To investigate the long-term results and visual outcomes of penetrating keratoplasty (PKP) in Peters anomaly. Twenty-three eyes from 22 patients with Peters anomaly who underwent PKP from 1998 to 2008 were reviewed retrospectively. Patients who were followed for more than 3 years after the first PKP were included in this study. The systemic and ophthalmic features of the recipients were assessed, and the various prognostic factors for graft survival were evaluated. Disease severity was determined according to other accompanying eye anomalies in mild or severe form. The final visual outcomes were presented with respect to graft clarity. Among the 22 patients, 14 patients had unilateral disease, and eight patients had bilateral disease. Associated systemic anomalies were observed in six patients. The mean age at the first PKP was 42.4 months. Nineteen eyes (83 %) underwent PKP after 12 months of age. The graft failure rates at 1 year, 3 years, 5 years, and 10 years after PKP were 30 %, 39 %, 70 %, and 77 % respectively. Graft rejection within 1 month after PKP and severe disease were significant risk factors for graft failure. The mean final VAs in the clear-graft group and the failed-graft group were 1.883 logMAR and 2.767 logMA...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
