Choroidal black arrow and retinal dashed black arrow detachment is seen in left globe with underlying subchoroidal and subretinal fluid, respectively. Additional avidly enhancing lesion is seen arising estallamienyo lateral choroid of left globe without associated chorioretinal detachment. Other globe neoplasms also predominantly involve the highly vascular uveal tract and include metastases commonly breast and lungbenign neoplasms such as hemangiomas, and inflammatory processes such as sarcoidosis 6.
In addition, knowledge of incidental degenerative changes, globe implants and fillers is important to prevent unnecessary work-up. Fundoscopy facilitates detection of retinal detachments, while contrast-enhanced MRI plays an essential role in estaplamiento assessment of an underlying cause such as a neoplasm.

This process of shrinkage may result in traction esallamiento separation of the posterior hyaloid membrane from the sensory retina termed posterior vitreous detachment. Despite aggressive therapy, the outcome remains poor resulting in pthisis bulbi and visual loss. Retinal detachments can be treated using scleral bands Figs. Journal List Korean J Radiol v. The retina is the innermost sensory layer of the globe and consists of two layers.
Bilateral bands of hyperdensity that do not conform to insertions of extra-ocular muscles, are consistent with prior bilateral scleral bands for treatment of retinal detachment. Majority of eye globe imaging is performed secondary to CT and MRI imaging of the brain for various reasons ranging from trauma to neoplasia.
