Acute Unilateral Hypopyon Uveitis and Secondary Glaucoma in an Adult With Relapsing Acute Lymphoblastic Leukemia.

Anterior segment infiltration in acute lymphoblastic leukemia (ALL) presenting as hypopyon uveitis in an adult is rare. We report this case as an uncommon presentation in a patient in remission after chemotherapy for ALL. In addition to the hypopyon, the patient presented with congested eye caused by secondary raised intraocular pressure. There is a need to maintain a high index of clinical suspicion in uveitis cases, as early diagnosis of ocular malignancy can save vision. Atypical unilateral hypopyon, even in adults, can be an indication of relapsing ALL.
