More common signs should also be considered suspicious until proved otherwise, such as strabismus, the second most frequent sign of retinoblastoma.

Leukocoria is a sign observed by the naked eye or with a scope, often detected incidentally on routine eye examination, or in photographs; it is not a diagnosis. It may stabilize, although often with loss of central vision due to macular lipid deposits, or deteriorate with total exudative retinal detachment Figure 3diridis rubeosis, dignosis glaucoma, cataract, uveitis, phthisis bulbi and, ultimately, total and definitive loss of vision.

Learning Point Leukocoria can be caused dignosis congenital or acquired eye diseases.


There are 3 types:. Fifty-two forms of childhood cancer: Vitreous and subretinal seeding, along with calcifications, are the characteristics virtually pathognomonic of retinoblastoma Figure 2d.

Leukocoria may be present from stage 3 onwards. Ocular trauma can lead to cataract, retinal detachment, or vitreous hemorrhage, any of which can produce an abnormalred reflex. Aubin Balmer and Francis Munier. The vital prognosis for these cerebral leukoccoria is very poor. Second nonocular cancers in retinoblastoma: A decision was made to enucleate the eye because of the size of the tumor.

IOP may be elevated in both retinoblastoma and Coats disease secondary to anterior segment neovascularization. Open in a dagnosis window. A full family anamnesis is essential, with particular attention to any history of enucleation in infancy.

There are 3 types: Informed decisions about diagnostic and therapeutic interventions based on patient information and preferences, up-to-date scientific evidence, and clinical judgment is made. Cultures may be confirmatory. The retinopathy may arrest spontaneously at any point of the natural course of the disease, the critical period being the stage when neovascularization invades the vitreous, the retroequatorial zone and posterior pole.

The work-up was an immediate consultation with a pediatric ophthalmologist and the diagnosis of unilateral retinal detachment was made. These children have usually received oxygen therapy, and the first signs of retinopathy appear between 35 and 45 post-conceptional weeks.

Rarely, there may be linear dystrophic retinal calcifications from chronic retinal detachment at the level of RPE, unlike retinoblastoma, where the calcification is within the intraocular tumor. This is the diffuse infiltrating, or plaque-like form of retinoblastoma Morgan A true neoplasm, optic nerve glioma presents phases of rapid growth followed by stagnation, sometimes even spontaneous regression Parsa et al Clinical variations and complications of Coats disease in cases: Leukocoria, or any other unexplained ocular sign in an infant should always, until proved otherwise, invoke the possibility of a malignant tumor and put in motion all the necessary means for prompt diagnosis.


Differential diagnosis of leukocoria and strabismus, first presenting signs of retinoblastoma

diagnoeis Keeping in mind a possible diagnosis of retinoblastoma is the first major step to a full recovery. Sign in via Shibboleth. This article outlines a practical, stepwise approach to identifying key diagnostic findings in retinoblastoma and pseudoretinoblastomas. Early diagnosis is vital. National Center for Biotechnology InformationU. White pupillary reflex is typical of retinoblastoma Fig. Neuroimaging Clin N Am. Less frequent manifestations are inflammatory conditions resistant to treatment, hypopyon, orbital cellulitis, hyphema or heterochromia.

Retinoblastoma represents the greatest challenge in the field of ophthalmology. It is non hereditary, probably congenital, with no known associated systemic diseases.

Differential diagnosis of leukocoria and strabismus, first presenting signs of retinoblastoma.

Medulloepithelioma is a non hereditary tumor, usually unilateral, deriving from the immature embryonic non-pigmented ciliary body Andersen ; Broughton and Zimmerman or, more rarely, from the optic nerve or retina. Other causes of leukocoria are slightly more common but exact estimates of their incidence are not available. Retinal detachment from any other etiology e.
