What is an exudative retinal detachment?
Exudative retinal detachment happens when fluid builds up behind your retina, but there aren’t any tears or breaks in your retina. If enough fluid gets trapped behind your retina, it can push your retina away from the back of your eye and cause it to detach.
Which type of retinoblastoma causes retinal detachment?
Types of Retinal Detachments in Retinoblastoma. Exudative RD, rhegmatogenous RD, and tractional RD may occur in RB.
Why is there Leukocoria in retinoblastoma?
Leukocoria can be caused by abnormalities in the lens (eg, cataract), vitreous (eg, hemorrhage), or retina (eg, retinoblastoma) (table 1) [1,2]. It can be the initial manifestation of a wide spectrum of intraocular and systemic disease processes [3-7].
What are the differential diagnosis of retinoblastoma?
However, the differential diagnosis includes other entities such as a cataract, Coats’ disease, retinopathy of prematurity, toxocariasis, choroidal coloboma, vitreous hemorrhage, myelinated retinal nerve fibers, and other retinal tumors such as astrocytic hamartoma.
What is exudative retinopathy?
(FEVR) is a hereditary condition where the retinal blood vessels do not develop normally. As a result, scar tissue may develop which—as it contracts—can detach the retina and result in visual loss.
Can retinoblastoma cause retinal detachment?
Retinoblastoma (RB) is the most frequently seen intraocular cancer in children, a complication of which is retinal detachment (RD). While the main focus of treatment is curing the cancer and preserving the eye, the visual function is important to the patient’s quality of life.
Is retinoblastoma a intraocular tumor?
Retinoblastoma (Rb) is a rare form of cancer that rapidly develops from the immature cells of a retina, the light-detecting tissue of the eye. It is the most common primary malignant intraocular cancer in children, and it is almost exclusively found in young children….

What does the Tapetum look like?
Apart from its eyeshine, the tapetum lucidum itself has a color. It is often described as iridescent. In tigers it is greenish. In ruminants it may be golden green with a blue periphery, or whitish or pale blue with a lavender periphery.
Can you see retinoblastoma with the naked eye?
The retina develops from the centre out. Infants with retinoblastoma often have very pronounced white pupil in photographs. The reflex can also often be seen in low light with the naked eye.
What is trilateral retinoblastoma?
Abstract. Background: Trilateral retinoblastoma (TRB) is a syndrome consisting of unilateral or bilateral hereditary retinoblastoma (Rb) associated with an intracranial neuroblastic tumor. Although its incidence is low, the prognosis is very poor.
