Abstract
Purpose
Although there are significant risks, retrobulbar anesthesia is commonly used for eye surgery. We report two cases of Purtscher-like retinopathy, a rare complication.
Case summary
(Case 1) A 76-year-old female visited our hospital because of decreased vision. She underwent right cataract surgery with retrobulbar anesthesia. After 7 days, she had decreased visual acuity (VA) and a constricted visual field. Multiple white spots and cotton wool spots around the optic nerve and post pole, macular edema (ME), and subretinal fluid (SRF) were found using a fundus examination. A non-perfusion area and staining of the vascular wall were seen using fluorescence angiography. Although carotid arterial angiography, thrombolysis, and intravenous injection of high-dose steroids were performed, the ME and SRF persisted. After intravitreal aflibercept was injected twice (2-month interval), the ME and SRF decreased and remained stable. (Case 2) A 61-year-old male underwent left cataract surgery with retrobulbar anesthesia. After anesthesia, the VA of the left eye was 10 cm finger count. The fundus examination showed multiple hemorrhage blots and retinal hemorrhages, and hyperfluorescence around the optic nerve and post pole; vascular wall staining revealed a Purtscher-like retinopathy. Left carotid arterial angiography, thrombolysis, and intravenous injection of high-dose steroids were then performed. After treatment, the VA of the left eye, ME, and SRF were improved at the 4-month follow-up.
Figures and Tables
Figure 1
(Case 1) Initial examination after symtome occurred. (A) Seven days later fundus photography after cataract operation. Multiple cotton wool spots were observed. (B) Seven days later optical coherence tomography after cataract operation. There were macular edema and subretinal fluid. (C) Early phase of fluorescein angiography. There were areas of capillary non-perfusion with occluded retinal aterioles. (D) Late phase of fluorescein angiography. There was perivascular staining.

(Case 1) Follow-up after treatment. (A) Fundus photography after 8 months. Multiple cotton wool spots were improved. (B) Optical coherence tomography after 8 months. Macular edema and subretinal fluid were improved.

(Case 2) When visit out-patient department after retrobulbar anesthesia. (A) Retinal hemorrhage was observed in fundus photography. (B) Fluorescein angiography. There were perivascular staining and hyperfluorescence around optic disc. (C) Optical coherence tomography had macular edema and subretinal fluid.

(Case 2) Follow-up after treatment. (A) Fundus photography after 4 months. Multiple cotton wool spots were improved. (B) Fluorescein angiography. Perivascular staining and hyperfluorescence around optic disc were improved. (C) Optical coherence tomography after 4 months. Macular edema and subretinal fluid were improved.
