Axial T1W image of right globe. However, characteristic concavity at site of banding is not seen in this case.

Traumatismo ocular – Wikipedia, la enciclopedia libre

Anteriorly, choroidal detachments commonly extend into the ciliary body, whereas, retinal detachments are limited by the ora serrata. This process of shrinkage may result in traction causing separation of the posterior hyaloid membrane from the sensory retina termed posterior vitreous detachment.

Medial lesion shows contrast enhancement. The episcleral space is a potential space that can extend between the fascia and the sclera 1.

Estallamienyo sclera is altered in thickness and shape throughout life. Arch Pathol Lab Med. Please review our privacy policy. Disruption of the sclera can result from trauma globe rupture Figs.

The most common organisms include skin commensals such as staphylococcus epidermis, candida and parasites including cysticercosis and toxocariasis. Endophthalmitis represents inflammation or infection involving the anterior chamber and vitreous humour. Journal List Korean J Radiol v. CT or MR evaluation may be useful in posterior uveitis, for assessment of complications including chorioretinal detachment, underlying abscesses or foreign bodies providing a nidus for infection 9.


The layers are only tightly adherent at the optic disc and ora serrata where the RPE becomes continuous with the ciliary body.

Eye Globe Abnormalities on MR and CT in Adults: An Anatomical Approach

On MRI, the retina is in close apposition to the choroid in normal circumstances and cannot be ocuular separately 1.

The choroid merges with the ciliary body at the ora serrata and extends posteriorly to the optic nerve head.

Retinal detachments can be treated using scleral bands Figs. Male primary lung adenocarcinoma patient presenting with left sided blindness.

Non-contrast CT is useful in the initial evaluation of orbital and occular trauma for the assessment of fractures, extra-ocular muscle herniation and suspected globe rupture. Axial non-contrast image from brain CT assessment of altered mental state.

Ahmad SM, Esmaeli B. Metastatic tumors of the orbit and ocular adnexa. Find articles by Wai-Yung Yu. The sclera is enveloped by the fibroelastic Tenon’s capsule, which fuses with the bulbar conjunctiva and is perforated posteriorly by the optic ewtallamiento sheath. Table 1 shows the common MRI characteristics of the various structures in the globe.

Ciliary bodies estallamieento part of choroid dashed white arrows, B, C. In old age, the vitreous may shrink and form clumps leading to ‘floaters’. CT is the technique of choice for evaluating metallic or estallamienyo foreign bodies, whereas MRI is contraindicated due to potential migration and local heating. High-resolution MRI facilitates evaluation of chorioretinal detachments and potential underlying neoplasms.


On MR and CT, posterior vitreous detachment appears as a membrane within the vitreous cavity detached from the optic disc and attached at the ora serrata.

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. Find articles by Premilla Pillay. Rhegmatogenous detachments are commonly secondary to vitreous degeneration and traction on the retina.

Enhancing lesion suggestive of neoplastic cause is absent. Received Aug 23; Accepted Jun 5. Axial non-contrast image from brain CT for assessment of direct globe injury shows left globe rupture with complete loss of normal scleral contour, vitreous hemorrhage and surrounding periorbital and episcleral hematomas.

Lens black arrow and sclera white arrow show hypointense signal on all sequences. The distinction between choroidal and retinal detachment is not always possible ocupar MRI despite several known patterns.
