Avascular Peripheral Retina in Infants

Abstract

Avascular peripheral retina in an infant is a common characteristic of numerous pediatric retinal vascular disorders and often presents a diagnostic challenge to the clinician. In this review, key features of each disease in the differential diagnosis, from retinopathy of prematurity, familial exudative vitreoretinopathy, Coats disease, incontinentia pigmenti, Norrie disease, and persistent fetal vasculature, to other rare hematologic conditions and telomere disorders, will be discussed by expert ophthalmologists in the field.

Keywords: Avascular retina; Coats disease; Norrie disease; familial exudative vitreoretinopathy; incontinentia pigmenti; persistent fetal vasculature; retinopathy of prematurity.

Avascular peripheral retina with neovascularization (NV) and typical posterior hyaloid yellow deposits in a term neonate with familial exudative vitreoretinopathy. Corresponding fluorescein angiography shows straightening of the vessels towards the periphery, avascular peripheral retina, and severe leakage from the NV at the vascular-avascular retinal junction (Courtesy of Dr. Şengül Özdek)

Peripheral avascular retina in familial exudative vitreoretinopathy never shows forward advancement during the lifetime, has fine but adherent vitreous condensation at the edge, and often the temporal raphe is involved more posteriorly, like a ‘notch’. Avascularity is present in all quadrants but is more prominent temporally. There are no ghost vessels (Courtesy of Dr. Subhadra Jalali)

After the removal of fibrovascular membrane, bulb-shaped telangiectasias (white arrows) and subretinal exudates became prominent under perfluorocarbon liquid (B) (Courtesy of Dr. Shunji Kusaka)

A case of Coats’ disease with a peripheral avascular retina, mimicking familial exudative vitreoretinopathy. Color fundus photograph of Coats’ disease shows peripheral vascular proliferations and branched vessels, and exudative changes in the posterior pole. Fluorescein angiography of the same case shows peripheral avascular retina with bulb-shaped telangiectasias (white arrow), suggesting the diagnosis of Coats’ disease (Courtesy of Dr. Şengül Özdek)

Fundus photograph of the right eye shows total tractional retinal detachment with peripheral avascular retina and fibrovascular membranes causing anteroposterior traction in the center (C). Fundus photograph of the left eye shows near-normal posterior pole and lasered peripheral avascular areas (D). Fluorescein angiography highlights the abnormal vasculature. The right eye shows severe leakage from the fibrovascular membranes and totally avascular periphery (E). The left eye shows leaking pathological vessels at the avascular-vascular junction, posterior to the laser scars (F, G). (Courtesy of Dr. Şengül Özdek)

Persistent fetal vasculature in a 6-month-old boy presenting with leukocoria and exotropia of the right eye.40 Color fundus photograph of the right eye revealed a fibrovascular stalk extending from the optic nerve to the posterior lens capsule (A, B, C). Fluorescein angiography of the right eye shows retinal vessels in posterior retinal folds pulled anteriorly into the stalk up to the posterior lens (a, c), as well as peripheral retinal capillary nonperfusion (b).

Figure 12

A 40-day-old girl with Adams-Oliver syndrome presenting with tractional retinal detachment in both eyes (A, B). Fundoscopic examination of the right eye revealed extensive fibrosis involving the optic nerve and the posterior pole (A). The left eye showed a radial falciform retinal fold extending from the macula to temporal periphery (B). Fluorescein angiography of the right eye showed dilated leaking vessels at the center and abrupt termination of the vascularization with bulb-shaped ends in the midperiphery (C). The left eye showed tortuous vessels and capillary nonperfusion areas. There was an abrupt termination of vascularization at the temporal macula and straightening of vessels, as well as posterior leakage (D). The patient underwent lens-sparing vitrectomy with membrane peeling and endolaser in both eyes, which resulted in retinal attachment (E, F). Genetic testing revealed homozygous mutation in the DOCK6 gene. (Courtesy of Dr. Şengül Özdek)
