The white pupillary reflex comes up in photos or can be caught by a clinician on routine direct ophthalmoscopy. Strabismus is also a common presenting sign, and one reason every child needs a dilated eye exam who develops strabismus.
Retinoblastoma: An overview - PMC - PubMed Central (PMC)
Direct visualization of the tumor by an indirect ophthalmoscope is diagnostic for retinoblastoma in over 90% of cases. 20 RetCam is a wide-angle fundus camera, useful in accurately documenting retinoblastoma and monitoring response to therapy.
Retinoblastoma: Evaluation and Diagnosis | SpringerLink
2019年4月24日 · Indirect ophthalmoscopy is used to evaluate the fundus. An organized systematic approach to thoroughly assess the posterior pole is recommended to prevent overlooking important findings. This examination can be broken down into four parts to evaluate the vitreous, optic disk, macula, and peripheral retina including pars plana.
Mastering the Art of Pediatric Retina Examinations
Ultra-widefield fundus images obtained with the Optos systems are often successful in children older than 3 years. In photophobic individuals, fundus photography may be better tolerated than binocular indirect ophthalmoscopic examination.
Retinoblastoma: Clinical Presentation and the Role of …
At that examination, we perform indirect ophthalmoscopy, fundus photography, and A- and B-scan ocular sonography. We check corneal dimensions and the axial length of the eye, because persistent hyperplastic primary vitreous is associated with a foreshortened globe and is important in the differential diagnosis of retinoblastoma.
Both eyes should be examined with an indirect ophthalmoscope after pupillary di-lation to confirm a suspicion of retinoblastoma. Scleral depression may be withheld until ex-amination under anesthesia (EUA).
Retinoblastoma: Presentation, Evaluation, and Diagnosis
2019年4月19日 · Most patients with retinoblastoma have normal anterior segments but may have anterior cells or nodules on the iris. In exophytic tumors, visualization of retinal vasculature behind the lens may be possible as well. Indirect ophthalmoscopy should be performed to evaluate the posterior pole and fundus.

2020年6月25日 · Fundus photographs are taken during examination under anesthesia of a child with retinoblastoma by placing the endoscope just in front of the cornea while the assistant uses the manual focus of the smartphone camera to capture the photographs (b).
High resolution magnetic resonance imaging of retinoblastoma
Results: All retinoblastomas could be visualised as hypointense to vitreous on T2 weighted images and slightly hyperintense to vitreous on plain T1 weighted images with a moderate enhancement after contrast application. Histology revealed seven cases with infiltration of the optic disc or optic nerve.
Portable handheld optical coherence tomography (OCT) has enabled this imaging technique to be applied to the diagnosis and management of retinoblastoma. The high-resolution imaging provided by OCT enables enhanced detection of tumors, including those that are invisible on …
