68. IS VAGINAL DELIVERY HARMFUL TO PATIENTS WITH PSEUDOXANTHOMA ELASTICUM?

Author

Abstract

Fearing for possible consequences to the retina of women with pseudoxanthoma elasticum, vaginal delivery is sometimes discouraged. In our case series of 14 patients with pseudoxanthoma elasticum, we could not detect any (sub)retinal hemorrhages or progression of angioid streaks after childbirth. Vaginal delivery seems safe for the retina of patients with pseudoxanthoma elasticum if no active choroidal neovascularization is present. Background/Purpose: To investigate the effect of a vaginal delivery (VD) on retinal pathology in patients with pseudoxanthoma elasticum. Methods: Retrospective case series. All 14 consecutive women with pseudoxanthoma elasticum who visited the ophthalmology department during pregnancy and after delivery between 2010 and 2018 were included. Prepartum and postpartum imaging consisted of color imaging, near-infrared imaging, and optical coherence tomography and was assessed on occurrence of (sub)retinal hemorrhages and change in angioid streaks. Results: Fourteen patients (15 deliveries) were included, of whom 11 patients (79%) had a VD and three patients (21%) a secondary caesarian section. Data of three patients with VD (four deliveries) could not be assessed for (sub)retinal hemorrhage within 10 weeks postpartum. The median age at delivery was 31 years (IQR 29–37). One patient with VD (9%) had a choroidal neovascularization and was treated with anti-VEGF injections before assisted delivery. All patients had angioid streaks in the central 5,500 µ m of the posterior pole of both eyes. After delivery, no patient in the VD or caesarian section group presented with progression of angioid streaks or (sub)retinal hemorrhage. Conclusion: Pushing during the expulsion phase of VD seems safe in pseudoxanthoma elasticum patients without active choroidal neovascularization, and the presence of angioid streaks alone should not be an indication for elective caesarian section.

70. Blind spot and visual field anisotropy detection with flicker pupil perimetry across brightness and task variations

Abstract

The pupil can be used as an objective measure for testing sensitivities across the visual field (pupil perimetry; PP). The recently developed gaze-contingent flicker PP (gcFPP) is a promising novel form of PP, with improved sensitivity due to retinotopically stable and repeated flickering stimulations, in a short time span. As a diagnostic tool gcFPP has not yet been benchmarked in healthy individuals. The main aims of the current study were to investigate whether gcFPP has the sensitivity to detect the blind spot, and upper versus lower visual field differences that were found before in previous studies. An additional aim was to test for the effects of attentional requirements and background luminance. A total of thirty individuals were tested with gcFPP across two separate experiments. The results showed that pupil oscillation amplitudes were smaller for stimuli presented inside as compared to outside the blind spot. Amplitudes also decreased as a function of eccentricity (i.e., distance to fixation) and were larger for upper as compared to lower visual fields. We measured the strongest and most sensitive pupil responses to stimuli presented on dark- and mid-gray backgrounds, and when observers covertly focused their attention to the flickering stimulus. GcFPP thus evokes pupil responses that are sensitive enough to detect local, and global differences in pupil sensitivity. The findings further encourage (1) the use of a gray background to prevent straylight without affecting gcFPPs sensitivity and (2) the use of an attention task to enhance pupil sensitivity.

Abstract

The assessment of the visual field in young children continues to be a challenge. Children often do not sit still, fail to fixate stimuli for longer durations, and have limited verbal capacity to report visibility. Therefore, we introduced a head-mounted VR display with gazecontingent flicker pupil perimetry (VRgcFPP). We presented large flickering patches at different eccentricities and angles in the periphery to evoke pupillary oscillations, and three fixation stimulus conditions to determine best practices for optimal fixation and pupil response quality. A total of twenty children (3-11y) passively fixated a dot, counted the repeated appearance of an animated character (counting task), and watched an animated movie in separate trials of 80s each (20 patch locations, 4s per location). The results showed that gaze precision and accuracy did not differ significantly across the fixation conditions but pupil amplitudes were strongest for the dot and count task. The VR set-up appears to be an ideal apparatus for children to allow free range of movement, an engaging visual task, and reliable eye measurements. We recommend the use of the fixation counting task for pupil perimetry because children enjoyed it the most and it achieved strongest pupil responses. [ABSTRACT FROM AUTHOR]
