Table 1. T1W and T2W Characteristics of Globe Structures.

Layer MRI Sequences-Normal Anatomical Features Pathology by Region
T1W T2W
Tenon's capsule Not usually visible. Can be distended by fluid/hemorrhage accumulating in potential episcleral space Effusions due to infection, inflammation, trauma (hemorrhage), neoplasms/metastases (Figs. 2, 3)
Cornea Hypointense-can be highlighted by an overlying T1W hyperintense tear film Hypointense Traumatic, infective/inflammatory disruption (Figs. 4, 5)
Sclera Hypointense Hypointense Episcleritis/scleritis: exudative chorioretinal detachment (Fig. 3)
Staphylomas (Fig. 6)
Colobomas
Phthisis bulbi (Figs. 7, 8)
Scleral bands (Figs. 8, 9)
Scleral calcifications (Fig. 10)
Uveal tract, choroid Hyperintense Hypointense Choroidal detachments (Figs. 11, 12, 13)
Retina Hyperintense-not usually seen separately from underlying choroid Hypointense Retinal detachments (Fig. 11)
Treated detachment, e.g., scleral bands (Figs. 8, 9), silicone oil (Fig. 14), and pneumatic retinopexy (Fig. 15)
Ocular neoplasms: melanoma (Fig. 16), metastases (Fig. 17), vascular neoplasms/phakomatoses (Fig. 18)
Uveitis (Fig. 19)
Aqueous/vitreous humour Hypointense Hyperintense Endophthalmitis
Posterior vitreous detachment
Lens Hypointense Hypointense Lens prostheses
Lens dislocation (Fig. 20)
