The role of the primary keukocoria physician Whether the family doctor or pediatrician, the primary care physician is usually the first to be confronted with the problem and thus plays an essential role, as the evolution and ultimate outcome of the disease will depend on the speed of reaction at this initial leukocoriz.

Newer studies have indicated a somatic mutation in the NDP gene mutant in Norrie disease in Coats disease. View All Subscription Options.

Second nonocular cancers in retinoblastoma: Please review our privacy policy. A white pupil is most often initially noticed by close family members Abramson et al or on flash photography, this often the primary reason for consultation. Discussion Retinal detachment is not common in infants and children and usually is caused by trauma or retinopathy of prematurity.

Associated findings include microphthalmia, microcornea, shallow anterior chamber, persistent tunica vasculosa lentis, cataract, fine vessels coursing over the iris to the anterior lens surface, and retrolental fibrovascular membrane. The primary sign is leukocoria. Most importantly, any leukocoria must be sought out with the use of a pen torch under subdued lighting McLaughlin and Levin PHPV is non hereditary. This is the diffuse infiltrating, or plaque-like form of retinoblastoma Morgan He was taken to the operating room and had the detachment surgically corrected.

In the absence of the classical clinical triad or with atypical retinal lesions, diagnosis of retinal astrocytic hamartoma may also be problematic.

OCT optical coherence tomography is used more and more frequently to evaluate macular tumors or simulating lesions. Leukocoria means a white leuko reflex from the pupil coria.

An investigatory and analytic thinking approach to the clinical situation is demonstrated. All positions of gaze should be elicited, first of all in miosis then repeated with the pupil dignosis dilated, taking advantage of mydriasis to detect any anomaly of the macular or papillary region on ophthalmoscopy. Subretinal fluid and retinal detachment without a solid retinal mass Fig.

Unchecked, traction from the proliferation will cause initially a partial retinal detachment stage 4ultimately a total detachment stage 5finally resulting in the cicatricial stage of retrolental fibroplasia.

In preverbal children, Teller visual acuity measurements can be obtained. Sign in via Shibboleth. Leukocoria from retinoblastoma is caused by the whitish well-circumscribed retinal mass.


Medulloepithelioma 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. Magnetic resonance imaging MRI is ideal for detecting any budding asymptomatic tumor of the pineal gland or optic chiasma in hereditary bilateral multifocal cases trilateral retinoblastoma.

There are 3 types:. Please enter User Name Password Error: First manifestations usually occur in early childhood, occasionally in the adult, with leukocoria, poor vision and typically a vascularized iris mass, this greyish or salmon-colored, in some cases pigmented. Ultrasonography showed a pattern consistent with calcifications within the tumor, and suggestive of retinoblastoma. Precise diagnosis ensures appropriate and early treatment to prevent irreversible blindness from primary pathology, secondary amblyopia, or life-threatening malignancies.

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

In the adult, optic nerve glioma is malignant and invariably fatal due to involvement of the chiasma and cerebral structures. Shorter time to diagnosis and improved stage at presentation in Swiss patients with retinoblastoma treated from to Capillary growth on the line of demarcation forms a prominent ridge stage 2a neoproliferation that may reach beyond the retina, infiltrating the internal limiting membrane and extending into the vitreous stage 3.

Persistent hyperplastic primary vitreous. Relative frequency of the lesions which simulate retinoblastoma. Difficult diagnosis Diagnosis of retinoblastoma or pseudo-retinoblastoma is much more difficult with opaque media or with atypical features.
