PURPOSE: To describe a previously unreported case of Purtscher-like retinopathy secondary to severe acute renal failure associated with squamous cell carcinoma of the cervix.
METHODS: This is a case report.
RESULTS: A 31-year-old female presented with a week history of acute abdominal pain, vomiting and severe renal failure followed by a sudden onset of bilateral visual loss. Vision was hand movement in either eye with central scotoma. Ophthalmic examination demonstrated bilateral retinal thickening and whitening with intraretinal hemorrhages localized to the peripapillary area, consistent with the diagnosis of Purtscher-like retinopathy. Further systemic examination revealed bilateral hydronephrosis secondary to underlying undiagnosed cervical carcinoma. Patient was treated with a short course of high-dose steroids. At 2 months, patient vision remained poor despite the resolution of retinal edema and hemorrhages.
CONCLUSIONS: This case serves as the first report of Purtscher-like retinopathy secondary to acute renal failure associated with cervical carcinoma, expanding the list of causes of Purtscher's or Purtscher-like retinopathies. In the presence of significant uremia and absence of previously known association, the authors postulate that the sudden surge of uremia causes increase of endothelin-1 (a potent vasoconstrictor), resulting in downstream endothelin-induced vasculopathy with subsequent occlusion of the pre-capillary arteriolar network.
