Overview

Retinoblastoma must be differentiated from other diseases that cause leukocoria. leukocoria may occur in several ocular conditions including tumors, vascular disease, inflammatory disorders, and also due to trauma.

Differentiating Retinoblastoma from Other Diseases

Retinoblastoma must be differentiated from other diseases that cause leukocoria. Differential diagnosis of leukocoria in children include:

Congenital malformations
 
 
 
Vascular diseases
 
 
 
Inflammatory diseases
 
 
 
Trauma
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Retinoblastoma
Medulloepithelioma
Leukemia
Combined retinal hamartoma
Astrocytic hamartoma (Bourneville’s tuberous sclerosis)
 
 
 
Persistent fetal vasculature (PFV)
Posterior coloboma
Retinal fold
Myelinated nerve fibers
Morning glory syndrome
Retinal dysplasia
Norrie’s disease
Incontinentia pigmenti
Cataract
 
 
 
Retinopathy of prematurity (ROP)
Coats’ disease
Familial exudative vitreoretinopathy (FEVR)
 
 
 
Ocular toxocariasis
Congenital toxoplasmosis
Congenital cytomegalovirus retinitis
Herpes simplex retinitis
Other types of fetal iridochoroiditis
Endophthalmitis
 
 
 
Intraocular foreign body
Vitreous hemorrhage
Retinal detachment
 
The above algorithm is adopted from Clinical Ophthalmic Oncology book [1]

Retinoblastoma should be differentiated from the following conditions that cause leukocoria:

Disease/Condition Clinical presentation Demographics/History Diagnosis Other notes
Retinoblastoma[2][3]
Coats'disease[4][5]
  • Sporadic in 100% of the cases
  • Almost always unilateral
  • More common among boys
  • The median age of diagnosis 5 to 9 years
Persistent fetal vasculature (formerly known as persistent hyperplastic primary vitreous)[5]
Astrocytic hamartoma[1]
Retinopathy of prematurity (ROP)[1]
  • Short axial length of eyes
Ocular toxocariasis [1]
  • Presence of retinal and/or vitreous traction in approximately all of the cases
Familial Exudative Vitreoretinopathy (FEVR)[6]
Norrie’s Disease[1][7]
