“…OCT can provide images of the contour of the posterior retina and has been used to describe different kinds of retinal abnormalities [16,17] ; however, OCT scans are limited to the macular area, and the exact shape of the entire posterior segment of the eye is difficult to obtain. MRI, especially 2D MRI, has gradually become a method by which to evaluate the shape of the eye [18][19][20] .…”

Purpose: To quantitatively analyze the shape of eyes with high myopia and provide assistance for posterior scleral reinforcement (PSR) using high-resolution three-dimensional (3D) magnetic resonance imaging (MRI). Method: In all, 260 eyes of 134 patients with high myopia were assessed in this study; 120 emmetropic volunteers were enrolled as a control group. The subjects were examined using 3D T2-weighted CUBE sequences. Results: The eyeballs' axial, horizontal, and vertical lengths were longer and their volume was larger in the subjects with high myopia than in those with emmetropia. The sites of the four recti and optic nerve attachment to the eye were clearly seen on 3D MRI, and the geometric information could be quantified for PSR preparation. The scleral strip was revealed by 3D MRI after surgery. Conclusions: 3D MRI can quantitatively analyze the shape of eyes with high myopia. 3D MRI examination might be necessary before and after PSR for preoperative preparation and postoperative assessment.

“…If a foreign body is located near important neural or vascular structures or other soft tissues, MR examinations must be avoided 14 . Approximately onethird of the orbit is occupied by the globe while the rest of the orbit is composed of fat, nerves, muscles, and vasculature 17 . Nevertheless, regardless of whether such small ferromagnetic IOFBs might result in MR-induced ocular injury, it is vital that they are visualised because misdiagnosis could result in ocular toxicity, and retinal inflammation, discolouration of the iris, siderosis and cataract formation 18,19 .…”

“…At this point in time, the literature suggests that the use of MRI in ocular lesions best serves as a compliment to ultrasonography and ophthalmologic examination [27]. This may be the result of a lack in accuracy with diagnosing uveal melanomas solely by MRI.…”

Background/Aims: This study describes patterns of intraocular lesions on T2 fluid-attenuated inversion recovery (FLAIR) imaging, exploring a prospective role of FLAIR imaging sequence in diagnosis and treatment. Methods: A retrospective study of orbital magnetic resonance imaging (MRI) studies from the years 2000 to 2015 was performed. MRI sequences included: pre-contrast T1-weighted, T2-weighted, T2 FLAIR, and postcontrast T1 and T2 imaging gadolinium, which were evaluated by a neuroradiologist. Two cases of melanoma were correlated to their pathology. Results: Twenty-four patients with intraocular pathology were evaluated. All lesions, regardless of pigmentation, revealed previously described melanotic patterns on T1- and T2-weighted images; 80% of 10 melanomas localized were hyperintense on T2 FLAIR, which better delineated lesion margins. All of the four inflammatory pathologies on T2 FLAIR were hyperintense, as were 80% of the amelanotic neoplasms. Pathology of two large uveal melanomas paralleled the findings seen on T2 FLAIR. Conclusions: T2 FLAIR appears beneficial in the demarcation of pigmented ocular lesions and may aid in determining protein content or previous treatment. Data also promote previous assertions that blood flow impacts intensity of lesions on T2 FLAIR. Further research is warranted.
