If the SIRS criteria are negative, it is very unlikely the person has sepsis; if it is positive, there is just a moderate probability that the person has sepsis. According to SIRS, there were different levels of sepsis: sepsis, severe sepsis, and septic shock. The definition of SIRS is shown below:

SIRS is the presence of two or more of the following: abnormal body temperature, heart rate, respiratory rate, or blood gas, and white blood cell count. Sepsis is defined as SIRS in response to an infectious process. Severe sepsis is defined as sepsis with sepsis-induced organ dysfunction or tissue hypoperfusion (manifesting as hypotension, elevated lactate, or decreased urine output). Severe sepsis is an infectious disease state associated with multiple organ dysfunction syndrome (MODS)
Septic shock is severe sepsis plus persistently low blood pressure, despite the administration of intravenous fluids.In 2016 a new consensus was reached to replace screening by systemic inflammatory response syndrome (SIRS) with the sequential organ failure assessment (SOFA score) and the abbreviated version (qSOFA). The three criteria for the qSOFA score include a respiratory rate greater than or equal to 22 breaths per minute, systolic blood pressure 100 mmHg or less and altered mental status. Sepsis is suspected when 2 of the qSOFA criteria are met. The SOFA score was intended to be used in the intensive care unit (ICU) where it is administered upon admission to the ICU and then repeated every 48 hours, whereas the qSOFA could be used outside the ICU.
The authors conclude that current evidence does not show a benefit of either intravenous or oral corticosteroids for rate of recovery of vision (in terms of visual acuity, contrast sensitivity, or visual fields). There are a number of reasons why this might be the case. Epidemiology
Optic neuritis typically affects young adults ranging from 18–45 years of age, with a mean age of 30–35 years. There is a strong female predominance. The annual incidence is approximately 5/100,000, with a prevalence estimated to be 115/100,000. Society and culture
In Charles Dickens Bleak House, the main character, Esther Summerville, has a transient episode of visual loss, the symptoms of which  are also seen in people who have optic neuritis. Legal historian Sir William Searle Holdsworth, suggested that the events in Bleak House took place in 1827. In an episode of Dr. Quinn, Medicine Woman ("Season of Miracles", season five), Reverend Timothy Johnson is struck blind by optic neuritis on Christmas Day 1872. He remains blind for the duration of the series. See also
