• W4300518508 abstract "<i>Background</i>: The intraocular manifestations of leukemia are diverse. The retina is the most common ophthalmic involvement site. The most common retinal manifestations of acute lymphoblastic leukemia (ALL) include dilated and tortuous vessels, serous retinal detachment (SRD), intraretinal hemorrhages as well as roth spots. Optic nerve infiltration and retinal neovascularization are unusual, especially in complete clinical remission of ALL. However, neovascularization in optic disk has not been observed in ALL during complete clinical remission. <i>Objective</i>: To report clinical characteristics of a bilateral optic disk neovascularization associated with relapse of ALL. <i>Method</i>: A 31-year-old male with ALL after having reached complete remission from chemotherapy complained about a vision loss in both eyes. First examination showed that best corrected visual acuity (BCVA) was 20/200 for his right eye and 20/160 for his left eye, respectively. Fundus examination revealed bilateral profound optic disk edema with multiple yellow-white exudates and retinal hemorrhages. Optical coherence tomography (OCT) showed bilateral optic disk edema and SRD in both maculas. Fundus fluorescein angiography (FFA) showed bilateral optic disk neovascularization. All these changes were present in remission. The patient received intravitreal Conbercept injection 0.5 mg (10 mg/ml) in both eyes for once on June 29, 2019. Optic disk neovascularization resolved three weeks after treatment. BCVA improved to 20/200 in his right eye, but still light perception in his right eye. No optic disk neovascularization recurrence was observed in 3-month follow-up. BCVA of the right eye maintained 20/200 at the latest follow-up. After intravitreal injection for 4 months the patient suffered from cerebral hemorrhage. He received bone marrow biopsy and cerebrospinal fluid sampling. The results showed relapse in hemogram and lymphocytes in central nervous system (CNS). Therefore, the chemotherapy treatment did not cause a new remission of the disease and the patient failed to recover. <i>Conclusion</i>: Optic disk neovascularization may appear as a sign of extramedullary relapse of ALL months in advance of the hematologic relapse. Intravitreal injection of conbercept could be beneficial and safe in treating this neovascularization." @default.
