The use of anticancer chemotherapy (ACC) has resulted in longer patient survival but has also increased drug-related adverse effects. A 22-year-old female receiving cisplatin-based intravenous chemotherapy for high risk variant of gestational trophoblastic neoplasia (GTN) presented with complaints of sudden painless loss of vision in her right eye for a duration of 4 hours. Ocular findings were suggestive of central retinal artery occlusion (CRAO). After exclusion of other potential aetiological risk factors, the patient was diagnosed with CRAO associated with cisplatin. Cancer patients are prone to thromboembolic events (TEE) not only due to primary disease but also due to underlying comorbidities and treatment modalities. The high incidence of TEE in patients under cisplatin therapy mandates a high degree of suspicion among the treating physicians. This rare possibility of irreversible visual toxicity should also be considered among the patients under cisplatin chemotherapy.
