“…The ability to visualize signals in the retrobulbar tissue beyond the sclera is known to be dependent on the wavelength used by the OCT technology [13,[17][18][19][20]. In this study, no differences were observed in the group of control eyes where the choroidal thickness is expected to be thicker compared to myopic eyes, which may reduce the chance to image even deeper structures.…”

Background: To compare four different optical coherence tomography (OCT) devices for visualization of retinal and subretinal layers in highly myopic eyes. Methods: In this prospective, observational, cross-sectional study, consecutive patients with high myopia and control subjects were imaged by four OCT devices: Spectralis OCT2, PlexElite 2.0 100 kHz, PlexElite 2.0 200 kHz and the Canon Xephilio OCT-S1. The acquisition protocol for comparison consisted of single vertical and horizontal line scans centered on the fovea. Comparison between the devices in the extent of visible retina, presence of conjugate image or mirror artifacts, visibility of the sclerochoroidal interface and retrobulbar tissue. Results: 30 eyes with high myopia and 30 control subjects were analyzed. The visualized RPE length was significantly different between the OCT devices with Xephilio OCT-S1 imaging the largest extent (p < 0.0001). The proportion of eyes with conjugate image artifact was significantly higher with the Spectralis OCT (p < 0.0001), and lower with the PlexElite 200 kHz (p < 0.0001). No difference in visibility of the sclerochoroidal interface was noted among instruments. The retrobulbar tissue was visible in a higher proportion of eyes using swept-source PlexElite 100 kHz and 200 kHz (p < 0.007) compared to the other devices. Conclusions: In highly myopic eyes, the four OCT devices demonstrated significant differences in the extent of the retina imaged, in the prevalence of conjugate image artifact, and in the visualization of the retrobulbar tissue.

AIM: To investigate the clinical features of adult patients with ocular toxocariasis (OT) in north China and to diagnose adults OT patients in early stage. METHODS: Clinical data of 24 adults with OT were retrospectively analyzed. Slit lamp photographs and fundus photographs and other imaging examinations of all the patients were reviewed. A questionnaire concerning the pet ownership and place of residence was completed to investigate the possible infection origin. Descriptive statistical analyses were performed on the demographic data, clinical features, funduscopic findings and ELISA results. RESULTS: Among the 24 patients diagnosed with OT by Toxocara IgG antibody in intraocular fluid, 16 (66.7%) eyes were right eye. The onset age of 12 eyes (50.0%) was between 30 and 40 years old, and 21 (87.5%) eyes were of peripheral granuloma type. The most common sign was vitreous opacity. Granulomas were detected in all the eyes, and 20 (83.3%) patients resided in rural area. In 4 patients, the concentration of anti-Toxocara antibody both in anterior humor and in vitreous humor were detected, and the results showed the concentration in vitreous humor was much higher than aqueous humor. CONCLUSION: Our study analyzes the clinical manifestation of OT in adults, which may have been under-recognized before. Eye side, residence, and detection of granuloma may help us in diagnosis of OT in patients with monocular vitreous opacity. For adult patients with presumed OT, negative results of anti-Toxocara antibody in anterior humor cannot rule out the possibility of OT, further detection of vitreous humor is suggested for final diagnosis.
