A 30-year-old woman with a dry cough and erythema nodosum undergoes fundoscopy during evaluation of her uveitis. Fluorescein angiography demonstrates segmental perivenous staining with focal white perivascular exudates along the retinal veins. This angiographic and fundus finding is classically described as:

• A Headlight in the fog
• B Sunset glow fundus
• C Snowbanking over the pars plana
• D Candle wax drippings (taches de bougie) ✓

Explanation

Segmental periphlebitis with focal white exudates coating the veins, called candle wax drippings or taches de bougie, is characteristic of sarcoidosis uveitis and reflects granulomatous periphlebitis. It is among the most specific fundus signs of ocular sarcoidosis. Headlight in the fog describes active toxoplasmic retinochoroiditis beside an old scar, snowbanking belongs to intermediate uveitis, and sunset glow fundus is diffuse choroidal depigmentation seen in Vogt-Koyanagi-Harada disease.
