Before confirming the diagnosis, it's important to keep in mind that there are similar conditions that demonstrate similar signs and symptoms, such as herpes keratitis, corneal abrasion and infectious corneal ulcer. In order to diagnosis<unk> , it’s essential to take a look at the history, meaning what the patient was doing prior to attending the emergency room or a day before. Also, particular attention should be placed on the timeline of the pain and discomfort. Biomicroscopy will show the extent of corneal damage and amount of remaining epithelium present, which will assist in providing a confirmation of the diagnosis. An essential factor is considering the time of year, since<unk>  generally occurs only between late October and early March. In addition, the higher the pain level, the more likely the<unk>  presentation. Patients with this condition generally arrive at the hospital with severe pain, in which their hand does not leave the affected eye due to the amount of pain. The time frame of the pain is usually instantaneous, which causes an individual to wake up in the early hours of the morning with increasing eye pain. This pain only continues to increase, regardless of the person's best attempt to reduce the aggravation. In addition, there is a stain with fluorescein that demonstrates a bright green splash in the cornea. The epithelium in the surrounding area of the infected eye is often disrupted and it demonstrates a considerable amount lost. In the very early stages, the desquamation starts off patchy and then progresses to covering up to 80% of the corneal surface. There is no iritis, corneal stroma or breech of Bowman’s membrane. The ulceration can be accompanied by conjunctivitis, without mucus or pus, in addition to oedema of the lids. Lastly, there is no regional lymphadenopathy and the second eye is not affected.
