Fig. 29. Papillitis; neuroretinitis. A. Fundus of an 8-year-old boy who complained of visual loss 2 weeks after his 4-year-old sister developed mumps. Note mild disc swelling and deep retinal exudates in the form of a macular star. Vision of 20/80 (6/24) ultimately cleared to 20/15 (6/5) with no therapy. B. Acute loss of vision in a 27-year-old healthy woman. Prepapillary haze is due to cells in the vitreous. Arteries are narrowed, and the peripapillary retina is thick and elevated. Retinal exudates surround the disc and form a macular hemistar. Vision did not recover (20/200) (6/60) despite multiple retro-bulbar steroid injections.
