Youngest reported Seasonal Hyperacute Panuveitis case.

Seasonal Hyperacute Panuveitis (SHAPU) is a mysterious but rapidly devastating intraocular inflammatory disease reported only from Nepal during odd years after monsoon. Though it predominantly affects children, it has been reported between 9 months and 50 years age. But herein, we report a case of SHAPU in a 38-days-baby during 2017 SHAPU outbreak. Parents of a 38-days-healthy male baby from Pokhara noticed redness in child's right eye since 5 days (October 2017). They noticed the fall of a white moth from the tubelight over the child's face 1-day prior to symptom onset. On examination, both eyes followed and fixated at light. The right eye was congested with dense anterior chamber reaction and white pupillary reflex obscuring the glow of the retina. Ultrasonography showed hyperechoic vitreous shadows with choroidal thickening. Left eye was normal. The child underwent vitreous tap with core vitrectomy + lensectomy with intravitreal antibiotics and steroid ↓GA. The blood investigations were normal and the vitreous sample yielded no organism growth. Viral PCR analysis was negative. The intraocular inflammation decreased and fundal glow was visible. AND IMPORTANCE: SHAPU can occur in a child as young as 38 days. Link with moth remains the strongest suspect.
