Bilateral acute depigmentation of the iris (BADI): first reported case in Brazil

Bilateral acute depigmentation of the iris (BADI): first reported case in Brazil

“…Dear Editor, We have read with considerable interest the article entitled "Bilateral acute depigmentation of the iris (BADI): first reported case in Brazil", by Maestrini et al (1) . The authors describe a patient who was diagnosed as having BADI, which has attracted a lot of attention among ophthalmologists in recent years.…”

“…The first sub-type has a more benign course, a lower incidence of increased intraocular pressure (IOP), and reversibility of the iris changes without transillumination defects or pupil distortion. The second sub-type, BAIT, has diffuse iris transillumination and mydriatic/ atonic pupilla or distorted pupil, occasional posterior synechiae, and increased IOP (1) . Indeed, the first sub-type mentioned by the authors reflects the characteristic clinical features of the BADI (2) , and the second sub-type, referred to in the study as BAIT, shares some properties with BADI but has differentiating characteristic features (3) .…”

“…In addition, Maestrini et al (1) report that both conditions have a self-limited course and a good prognosis. However, BAIT cases may present with severe IOP rise, which is sometimes resistant to medical treatment and necessitates trabeculectomy surgery as in our case report (5) .…”

Bilateral acute depigmentation of the iris: a case report

“…Maestrini et al (2) described the first Brazilian case of this disease; however, as pointed by experts in this pathology in a letter to the editor (9) , deeper analysis of the case demonstrated that the characteristics were closer to another pathological condition called bilateral acute iris transillumination (BAIT). This disorder usually shows atonic dilated pupils and diffuse iris transillumination defects and has a higher incidence of IOP elevation (10) .…”

“…It was described for the first time in Turkey in 2006 (1) . It occurs more frequently in middle-aged women and is characterized by asymptomatic, bilateral, symmetrical, and simultaneous iris depigmentation with focal or diffuse stromal atrophy (2,3) . Although BADI is not usually associated with atrophy of the iris pigmented epithelium, pigment dispersion in the anterior chamber and pigment deposition in the trabecular meshwork have been reported.…”
