Several entities must be considered when a patient presents with a white dot syndrome. In most cases these can be distinguished from one another based on the appearance or distribution of the lesions, the clinical course, or patient variables such as age, sex, laterality, and functional and image examinations. In this paper we review the distinctive and shared features of the white dot syndromes, highlighting the clinical findings, diagnostic test results, proposed etiologies, treatment, and prognosis.

DUSN is an ocular inflammatory syndrome described by Gass 1 in 1977, and initially called the ''unilateral wipe-out syndrome.'' Later, the term ''diffuse unilateral subacute neuroretinitis'' was introduced and the presence of an intraocular nematode as a causative agent was reported. 2,3 Different sized parasites have been reported as possible etiologic agents of DUSN, including Ancilostoma caninum and Baylissascaris procyonis, however, these reports did not present conclusive evidence of a specific agent. [3][4][5] DUSN is usually unilateral, although bilateral disease has been reported, 6,7 tends to occur in children and young adults, and can lead to severe visual loss if left untreated. The mean age of DUSN patients is16.7 years, with >83% of patients being younger than 20 years. 7 The clinical course of DUSN was described by Gass and Scelfo. 2 The disease has 2 different stages: an early stage characterized by decreased visual acuity, papilitis, multifocal yellow-white lesions, vitritis, and vasculitis (Figs. 1, 2); and a late stage characterized by decreased visual acuity, mild vitritis, diffuse or focal retinal epithelial damage, optic nerve atrophy, retinal vessel narrowing, presence of small white spots (probable exudation residue), and the presence of subretinal tracks, suggesting remnants of larvae migration in the subretinal space (Fig. 3). 2,3,8,9 More recently, Garcia Filho and colleagues reported 121 patients with the clinical diagnosis of DUSN. Most patients presented in the late stage of the disease (92.6%) and the most prevalent clinical features were the presence of subretinal tracks (91.7%), focal alterations of the retinal pigmented epithelium (RPE) (89.3%), small white spots
