“…Advances in OCT technology offer a new opportunity to study vitreous structures. Noninvasive imaging of posterior vitreous structures, such as AM and BP, became possible with the introduction of spectral domain OCT [ 6 ]. Although most of the commercially available spectral domain OCT machines are best employed to visualize retina structures, imaging of the choroid and vitreous is also possible using a modified scanning technique [ 6 8 12 13 ].…”

Although most of the commercially available spectral domain OCT machines are best employed to visualize retina structures, imaging of the choroid and vitreous is also possible using a modified scanning technique [ 6 8 12 13 ]. Moreover, high-quality vitreous images can be obtained without special SS-OCT measures, because of SS-OCT's longer wavelength, fast scanning speed, and easy software enhancement [ 5 14 ].…”

“…One is the area of Martegiani (AM) at the posterior end of Cloquet's canal, which forms from the regressed hyaloid artery during fetal development and is located over the optic disc. The other is bursa premacularis (BP), which is also known as the posterior precortical vitreous pocket (PPVP) and is located above the macula [ 5 6 7 8 9 ]. The presence of BP has been confirmed by various methods, including Indian-ink injection in the postmortem eye [ 10 ], triamcinolone injection during vitrectomy [ 11 ], and, more recently, OCT [ 5 6 7 ].…”

PurposeTo evaluate posterior vitreous structures using swept-source (SS) optical coherence tomography (OCT) with en face imaging.MethodsWe retrospectively reviewed OCT images of healthy individuals who did not have intra-ocular disease. We obtained high-definition horizontal and vertical line scans crossing the fovea and 3D scans using SS-OCT, with the 3D scan centered between the fovea and the optic-nerve head. An enhanced vitreous visualization function was used to highlight vitreous structures. En face mode was used to measure the area of Martegiani (AM) and bursa premacularis (BP). We performed all measurements using a built-in function of the viewing software.ResultsWe enrolled 24 eyes from 12 healthy individuals. The mean patient age was 28.7 ± 4.6 years (range, 24 to 39 years). The mean AM and BP areas were 5.73 ± 0.88 and 18.76 ± 6.95 mm2, respectively. In en face imaging, AM shape was most frequently a vertical oval (18 / 22, 81.8%), while the predominant BP shape was round (16 / 20, 80.0%). AM was in contact with the optic disc, either at the temporal-disc margin (13 eyes, 59.1%) or the nasal optic-disc margin (9 eyes, 40.9%).ConclusionsPosterior vitreous structures, such as AM and BP, were readily visualized using en face imaging with SS-OCT. Investigating normal vitreous configuration might help in understanding changes in vitreous structures associated with retinal pathology.

“…Age, female gender, and myopia have been thought to be the risk factors for PVD, which was assessed by 90-diopter biomicroscopy or B-scan ultrasonography [ 21 – 23 ]. Recently, studies on OCT-based PVD evaluation have been introduced [ 10 , 11 , 24 ]. Although OCT-based technique enables us to sensitively detect serial evolution of PVD [ 11 ], the empty space of posterior precortical vitreous pocket can be misdiagnosed as complete PVD with OCT scans [ 24 ].…”

Purpose To evaluate the degree of psychological distress in symptomatic vitreous floater patients and to evaluate whether these psychological factors are associated with the severity of discomfort associated with vitreous floaters. Methods We recruited 61 patients with symptomatic vitreous floaters and 34 controls. The degree of posterior vitreous detachment (PVD) was evaluated using optical coherence tomography. We measured the level of depression, perceived stress, state, and trait anxiety and the degree of floater-associated discomfort with self-administered questionnaire. We compared psychological parameters between floater patients and control. We also compared clinical and psychological characteristics among different floater-associated discomfort severity groups. Results Symptomatic vitreous floater patients showed higher rate of complete PVD and higher psychological distress compared to the control. On multiple logistic regression analysis, complete PVD (p = 0.001), depression (p = 0.001), and younger age (p = 0.037) were significantly associated with symptomatic floaters. There were no significant differences in complete PVD rate among different discomfort groups, while severe discomfort group showed higher depression, perceived stress, and state and trait anxiety compared to the other two milder symptom groups. Conclusions Symptomatic vitreous floater patients showed substantial level of psychological distress, and the severity of floater symptoms was significantly associated with psychological distress.

“…However, in that study, a previous version of OCT was used in the evaluation, and the resolution of the device may not have been sufficient to detect fine alterations of the PVC (Kicova et al 2012). Recent studies using the spectral-domain or sweptsource OCT show high-resolution images of the PVC and suggest the usefulness of OCT in evaluating PVD (Liu et al 2014;Ma et al 2014;Pang et al 2014;Abdolrahimzadeh et al 2016;Kim et al 2016). However, due to the limited depth of imaging, OCT cannot visualize the whole vitreous cavity, and the physiologic presence of hyporeflective spaces, such as premacular bursa or Cloquet's canal, in front of the macula and optic disc may lead to a false-positive interpretation of PVD (Kim et al 2016(Kim et al , 2017.…”

Purpose: To compare the diagnostic ability of ultrasonography (US) and optical coherence tomography (OCT) in evaluating posterior vitreous detachment (PVD) status. Methods: In total, 124 eyes in 63 patients were prospectively enrolled. Posterior vitreous detachment (PVD) status was evaluated by two examiners independently using US and OCT (transverse scan with/without peripapillary scan). By combining all examination results from both examiners, a final agreement on the PVD status was made. Inter-observer agreement and inter-examination agreement on PVD detection were evaluated.Results: The inter-observer agreement on PVD grading based on US was substantial (kappa = 0.628). The inter-observer agreement on PVD grading based on OCT was almost perfect (transverse and peripapillary scan, kappa = 0.893; transverse scan only, kappa = 0.923). The PVD grading based on transverse and peripapillary OCT perfectly matched the final PVD grading (kappa = 1.00). The PVD grading made based on US and transverse scan only showed almost perfect agreement with the final PVD grading (US, kappa = 0.834; transverse scan only, kappa = 0.906). Conclusion: Both US and OCT could accurately evaluate PVD. The interpretation of the US images was more subjective, leading to lower inter-examiner agreement than that of the OCT. By adding peripapillary OCT scan images, the diagnostic ability of OCT was improved.
