Ophthalmic signs and complications of the COVID-19 infection

Coronavirus-19 infection caused a mysterious pandemic worldwide. Some people experienced flu-like symptoms, while others have died due to pulmonary complications. Besides droplet spread, other routes of infection started to be suspected, such as through eye contact. During the first phase of the pandemic, pulmonary symptoms were in focus, later other signs and symptoms were also published. Eyelid, anterior and posterior segment symptoms, neuro-ophthalmic complications, and orbital problems related to COVID-19 infections are discussed in this article. It is important to detect the serious signs and symptoms to prevent late, sight threatening complications of COVID-19 infection.

Runge–Kutta Pairs of Orders 6(5) with Coefficients Trained to Perform Best on Classical Orbits

We consider a family of explicit Runge–Kutta pairs of orders six and five without any additional property (reduced truncation errors, Hamiltonian preservation, symplecticness, etc.). This family offers five parameters that someone chooses freely. Then, we train them in order for the presented method to furnish the best results on a couple of Kepler orbits, a certain interval and tolerance. Consequently, we observe an efficient performance on a wide range of orbital problems (i.e., Kepler for a variety of eccentricities, perturbed Kepler with various disturbances, Arenstorf and Pleiades). About 1.8 digits of accuracy is gained on average over conventional pairs, which is truly remarkable for methods coming from the same family and order.

Intraorbital Wooden Foreign Body: A Case Report

Intraorbital foreign bodies are one of the commonly encountered orbital problems. They may be sight threatening due to the severity of injury or its complications and even life threatening if not managed appropriately. We present a case of a 24-year old female with history of fall injury from a tree with an impacted intraorbital wooden foreign body. The patient was treated with prophylactic intravenous antibiotics and prompt removal of the foreign body was done under general anesthesia in the operation theatre. The post operative visual recovery was excellent with significant improvement of ocular motility and limited improvement of ptosis. Hence even organic foreign bodies can have good prognosis with timely intervention.DOI: http://dx.doi.org/10.3126/jkmc.v3i3.12248Journal of Kathmandu Medical CollegeVol. 3, No. 3, Issue 9, Jul.-Sep., 2014, Page: 119-121
