Sunil Sapkota, Pokhara: Seasonal hyperacute panuveitis (SHAPU) is an eye disease which was reported for the first time in Pokhara in 1975. SHAPU is serious eye infection caused by the white moth. According to Dr. Hari Maya Gurung of Himalayan Eye Hospital, Pokhara, 20 patients have come into contact with doctors. Of them, 3 were referred to Kathmandu based Dhulikhel Hospital.
She said, ‘In the past, the Shapu was seen in gap of one year, but this year it has been seen continuously.’ If left untreated within 24 to 48 hours, there is a risk of losing the eyes sight. ‘During the treatment of the patient, they are taken to the operating room, pus filled with eye is removed and injection is given to dry the eye.’- she added. The extracted pus has been collected for special testing as it may contain bacteria or viruses. Surprisingly Shapu’s infection does not occur in both eyes at once, she said.
SHAPU can spread from the white moth which has thick hair on the body, horizontally on the head and vertical black stripes on the wings.
According to Dr. Indraman Maharjan, the disease have been seen even in adults who can take precautionary measures. So far no one has lost eye sight. In urban areas, moths are seen fluttering in the street lights. The dust in the body of any moths affects the eyes. In complex operations, the inner part of the eye is completely cleaned. Five people have been treated by injecting medicine inside the eye socket. Others have been treated by injecting it into pupil.
