Retinal Cases & Brief Reports
|March 6, 2018
Summary
Retinal cavernous hemangioma can present with intralesional calcifications, mimicking retinoblastoma in infants. This case highlights the importance of considering this rare condition in the differential diagnosis.
Area of Science:
- Ophthalmology
- Medical Imaging
- Pediatric Oncology
Background:
- Retinal cavernous hemangioma is a rare vascular malformation.
- It can be challenging to differentiate from other retinal masses, particularly in infants.
- Phleboliths (intralesional calcifications) are not typically associated with cavernous hemangiomas.

Induced Pluripotent Stem Cells
28.1K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...

Vision
60.3K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.
