Roth spots are white-centered hemorrhages which can be the first clinical presentation of an underlying systemic disorder such as subacute bacterial endocarditis, leukemia, and anemia. We present a case of Roth spots in a patient with acute myeloid leukemia.
Keywords: Leukemic retinopathy, retinal hemorrhages, Roth spots

A 21-year-old male presented with complaints of blurred vision in both the eyes, left eye more than right eye for the past 1 week. He was diagnosed with acute myeloid leukemia 2 weeks ago and was under chemotherapy. Best-corrected visual acuity was 6/6p in the right eye and 6/18 in the left eye. Anterior segment of both the eyes was within normal limits. Fundus examination showed bilateral multiple retinal hemorrhages comprising superficial flame-shaped hemorrhages, intraretinal hemorrhages, and white-centered hemorrhages in the posterior pole [Figure 1]a and [Figure 1]b. The left eye also had a subinternal limiting membrane (ILM) hemorrhage at the macula. Optical coherence tomography (OCT) of the right eye macula was normal. The OCT of the macula of the left eye showed hyperreflectivity beneath the ILM at the macula with shadow effect correlating to the sub-ILM hemorrhage on fundus examination [Figure 2]a and [Figure 2]b.

White-centered hemorrhages known as “Roth spots” result from retinal capillary rupture and extrusion of whole blood.
This is followed by platelet adhesion to the damaged endothelium initiating a coagulation cascade and formation of a white lesion in the center of the hemorrhage which is a platelet-fibrin thrombus.
They were first seen in individuals with subacute bacterial endocarditis. They can also be seen in other conditions such as leukemia, anemia, anoxia, carbon monoxide poisoning, preeclampsia, HIV retinopathy, hypertensive and diabetic retinopathy, neonatal birth trauma, shaken baby syndrome, intracranial hemorrhage from arteriovenous malformation, and ocular decompression following trabeculectomy.
In our case, the patient was already diagnosed with acute myeloid leukemia. Ocular complications of leukemia can either be direct due to leukemic infiltration or due to associated anemia and thrombocytopenia. Leukemic retinopathy can present with multiple preretinal and intraretinal hemorrhages that are usually present in the posterior pole, Roth's spots, cotton wool spots, exudates, retinal venous tortuosity, perivascular sheathing, and neovascularization. Retinopathy usually resolves with the treatment of leukemia with chemotherapy. It is particularly important to identify Roth spots on fundus examination as this could be the first clinical presentation in a case of leukemia or other underlying systemic conditions. Thorough clinical and general examination to rule out the above-mentioned systemic conditions along with laboratory investigations such as complete blood count, peripheral smear, erythrocyte sedimentation rate, C reactive protein, blood culture, blood pressure, and blood sugar levels is warranted in patients with Roth spots.
