Uveal Tract Middle Layer The uveal tract consists of the iris, ciliary body and choroid.
Subretinal fluid accumulation can occur in nonrhegmatogenous detachments secondary to underlying neoplasms and hemorrhage. Enhancement of detached choroid is also apparent as in Figure Axial non-contrast image from brain CT assessment of altered mental state. Globe Anatomy The globe occupies one third of the orbital volume, with the vitreous humour representing two-thirds of the volume of the globe 2. The layers are only tightly adherent at the optic disc and ora serrata where the RPE becomes continuous with ocualr ciliary body.

Other scleral findings include scleral banding for treatment of retinal detachment Figs. Malignant melanoma is most commonly unilateral and may present with pain or decreased visual acuity.
On CT, melanocytic melanomas appear slightly hyperdense and show contrast enhancement. The distinction between choroidal and retinal detachment is not always possible with MRI despite several known patterns.
The various pathological processes involving these layers are highlighted using case examples with fundoscopic correlation where appropriate. Anatomy estallamienfo pathology of the eye: The vascular uveal tract is the most common site for hematogenously disseminated metastases within the globe Fig. Lens The lens forms the posterior boundary of estllamiento anterior chamber and is attached to the ciliary body via the zonular fibers.
Non-contrast CT is useful in the initial evaluation of orbital and globe trauma for the assessment of fractures, extra-ocular muscle herniation and suspected globe rupture. Published online Aug The outer retinal pigment epithelium RPE is attached firmly to the choroid. Dedicated orbital MRI scans 1. Scleral bands would appear more linear, as compared to punctate calcifications observed. No choroidal detachment is detected. This patient had undergone silicone oil injection for treatment of retinal detachment.
Ciliochoroidal detachment extends anterior to expected location of ora serrata Awhite arrows.

Axial T1W image of right globe. Histology following resection of cerebellar lesion confirmed diagnosis of hemangioblastoma. Eye globe abnormalities can be readily detected on dedicated and non-dedicated CT and MR studies.
Knowledge of the imaging features of both traumatic and non-traumatic globe abnormalities is necessary to ensure appropriate ophthalmology referral and accurate diagnosis. Other globe shape abnormalities include colobomas congenital defects in the layers of the globe including the optic disc and phthisis bulbi representing an end-stage atrophic globe Figs. This process of shrinkage may result in traction oculag separation of the posterior hyaloid membrane from the sensory retina termed posterior vitreous detachment.
These calcifications represent normal part of aging.
Vascular lesions of the orbit: The technique is limited by lengthy scanning ocluar, increased cost compared to CT, and requirements for sedation in children and other non-compliant patient groups. Gas is noted in anterior vitreous compartment consistent with pneumatic retinopexy typically used in treatment of superior rhegmatogenous retinal detachments.

Find articles by Kong Yong Goh. Axial non-contrast image from brain CT for assessment of direct esatllamiento injury shows left globe rupture with complete loss of normal scleral contour, vitreous hemorrhage and surrounding periorbital and episcleral hematomas.
The episcleral space is a potential space that can extend between the fascia and the sclera 1. Right-sided lens prosthesis is noted.

Enhancement of choroid is noted Bwhite arrowwhich is expected in detachment due to inflammatory response. Choroidal black arrow and retinal dashed black arrow detachment is seen in left globe with underlying subchoroidal and subretinal fluid, respectively. Gradual visual loss is the most common clinical finding.
