ICAO codes are separate and different from IATA codes, which are generally used for airline timetables, reservations, and baggage tags. For example, the IATA code for London's Heathrow Airport is LHR and its ICAO code is EGLL. ICAO codes are commonly seen by passengers and the general public on flight-tracking services such as FlightAware, though passengers will more often see the IATA codes, on their tickets and their luggage tags.
Episcleritis is a relatively common, benign, self-limited inflammation of the episcleral tissues. There are two forms of this condition: nodular and simple. Nodular episcleritis is characterized by a discrete, elevated area of inflamed episcleral tissue. In simple episcleritis, vascular congestion is present in the absence of an obvious nodule. A 2013 study estimated incidence of episcleritis as 41.0 per 100,000 per year and prevalence at 52.6.
