Purpose: To report the first series of Seasonal Hyperacute Pan Uveitis (SHAPU) from Bhutan.
Methods: We retrospectively analyzed the patients with clinically diagnosed SHAPU treated in the referral center in the last 5 years. Data included demographics (age, sex, laterality), region, time of presentation (year, season) and treatment received.
Results: The series included 3 males and 2 females. The mean age was 16 years. Three patients had presented in autumn of 2021, and two in autumn of 2019. Four patients presented within 2 weeks of the onset of symptoms. All patients had either exposure or contact with white moths. All patients presented with unilateral sudden painless reduction in vision and low Intraocular pressure. Four patients required vitrectomy. The final visual acuity of 3 patients was >6/36, and one patient was 6/60.
Conclusions and importance: The time of presentation and early treatment intervention are crucial in achieving good visual prognosis in SHAPU.
