The role of ophthalmology in the COVID-19 pandemic

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causing coronavirus disease 19 (COVID-19) has led to a worldwide pandemic. This pandemic presents a huge challenge for the healthcare system and also for ophthalmologists. Previous studies and case reports indicated that SARS-CoV-2 also infects the conjunctiva resulting in conjunctivitis. In addition, infectious virus particles in the tear fluid can be potential sources of infection; however, the detection of SARS-CoV-2 RNA in the tear fluid has rarely been successful. Although isolated conjunctival involvement is highly unlikely, at the current point in time of the COVID-19 pandemic, practically every patient examined by an ophthalmologist could be infected with SARS-CoV-2. Therefore, protective and hygiene measures should currently be consistently followed to minimize the risk of spreading the virus. Currently, there are no treatment recommendations for conjunctivitis associated with COVID-19. Tear substitutes might be helpful for symptom relief but there is no evidence for a topical antiviral therapy. In the future ophthalmologists could play a decisive role in the screening of maculopathies that might occur during COVID-19 treatment using chloroquine or hydroxychloroquine

Diagnostics, clinical aspects and genetics of congenital corneal opacities

Background Congenital corneal opacities are comparatively rare diseases with high amblyogenic potential. Purpose The present work provides an overview of the diagnostics, clinical aspects and genetics of congenital corneal opacities. Methods A literature search was carried out to compile an overview and illustration with own clinical case examples. Results Differentiated diagnostics are of high importance in the treatment of patients with congenital corneal opacities. A close cooperation between the medical departments involved and also the parents is absolutely essential. The structured classification of congenital corneal opacities provides the basis for a targeted treatment. Discussion The causes and the clinical symptoms of congenital corneal opacities are manifold. The correct diagnosis should be made early and in an interdisciplinary manner. Based on this, conservative and surgical treatment measures can be planned and an impending development of amblyopia can be specifically counteracted
