Post dengue Purtsher-like retinopathy: a case report

Dengue fever is a common infectious disease that is caused by the dengue virus. This report presents the cases of two patients, a 20-year-old male with history of left renal transplant and a 34-year-old female with Acute Myeloid Leukaemia, who presented at Shifa International Hospital, Islamabad, with sudden, painless decreased vision following a dengue fever infection. The patients' clinical presentations, visual outcomes, fundus findings, and management approaches were carefully documented over six months. Both the patients were treated with non-steroidal anti-inflammatory eye drops, with Case 2 additionally receiving intravenous Methylprednisolone and surgical intervention for recurrent vitreous haemorrhage. They were regularly followed-up and were monitored with serial OCT scans. Both the patients showed improvement in subsequent fundus examinations, OCT scans revealed resolution of intra-retinal oedema and retinal thinning. However, there was only minimal improvement in best corrected visual acuity (BCVA) for both the patients. This case report highlights the importance of comprehensive ophthalmic evaluation, regular follow-up, and appropriate management in patients with post-dengue fever retinopathy.
