Vascular Tufts of the Pupillary Border Causing a Spontaneous Hyphaema

Don’t it make my blue eyes brown: heterochromia and other abnormalities of the iris

“…232,246 Spontaneous hyphaema, which may be complicated by secondary raised intraocular pressure, is a well-recognised complication of iris vascular tufts. 237,239,[247][248][249][250][251][252][253][254][255][256] Iris microhaemangiomas are thought to be hamartomas arising from the stromal blood vessels. 235 In 1983 Stur and Strasser 227 described a sectorial racemose arterio-venous malformation in a 32-year-old male.…”

Visual Outcome after Bilateral Implantation of Extended Depth of Focus Intraocular Lens in a Patient with Iris Microhemangiomas

“…Iris microhemangiomas (IMH), also known as iris vascular tufts or Cobb's tufts, consist of rare, acquired benign tumors of the iris stromal vasculature [1]. They appear as nodular clusters of small, tightly coiled, thin-walled blood vessels localized at the pupillary border [2].…”

“…They appear as nodular clusters of small, tightly coiled, thin-walled blood vessels localized at the pupillary border [2]. Usually bilateral, they mostly affect individuals older than 50 years [1,[3][4][5] and have been associated with certain systemic diseases including diabetes mellitus type II and myotonic dystrophy [5,6]. Histopathologically, IMH are defined as vascular hamartomas arising from the iris stroma, ranging from 15-150 µmin size [3,4,[7][8][9].…”

“…Although they are generally asymptomatic, the most common presenting complaint consists of sudden decrease in visual acuity due to hyphema [10][11][12]. Several cases of spontaneous hyphema secondary to IMH have been reported in the literature [1,3,4,8,10,11,[13][14][15][16][17][18][19][20][21]. In most occurrences, the hyphema appears as an isolated episode and can improve spontaneously with conservative management [1].…”

“…4,5 They typically occur bilaterally in otherwise healthy individuals above the age of 50 years 1,2,6,7 as well as in patients with acquired systemic diseases such as hypertension, 2 diabetes, 6,8,9 and myotonic dystrophy. 8,10 They have also been reported in some congenital conditions such as hereditary haemorrhagic telangiectasia, 11 orbital cavernous haemangioma 3 and with remnants of pupillary membrane.…”
