Purpose. The purpose of this study was to report a case of bilateral vitreopapillary traction, previously misdiagnosed as papilledema.Methods. A case report is presented of a 47-year-old woman with a prior diagnosis of papilledema, who is shown to have bilateral vitreopapillary traction rather than true optic disc swelling, confirmed by optical coherence tomography (OCT).Results. OCT showed vitreous traction surrounding the optic discs of both eyes. Fluorescein angiography demonstrated focal leakage of both discs.Conclusion. Bilateral disc elevation caused by vitreous traction can be confused with papilledema. In such cases, OCT can be used to arrive at the correct diagnosis. Although the phenomenon of vitreopapillary traction is well reported, this case indicates that not all ophthalmologists recognize the condition.

We describe a 7-year-old girl who developed exudation nasally to the right optic disc due to retinal arteriovenous malformation. Fluorescein angiography, spectral domain optical coherence tomography, and optical coherence tomography angiography were performed. We give an overview of the different imaging techniques and discuss the differential diagnosis. Since there was no visual impairment, no treatment was started. A spontaneous decrease in edema and exudation was noted after 6 months.

Abstract Background/Objectives To re-evaluate diabetic papillopathy using optical coherence tomography (OCT) for quantitative analysis of the peripapillary retinal nerve fibre layer (pRNFL), macular ganglion cell layer (mGCL) and inner nuclear layer (mINL) thickness. Subjects/Methods In this retrospective observational case series between June 2008 and July 2019 at Moorfields Eye hospital, 24 eyes of 22 patients with diabetes and optic disc swelling with confirmed diagnosis of NAION or diabetic papillopathy by neuro-ophthalmological assessment were included for evaluation of the pRNFL, mGCL and mINL thicknesses after resolution of optic disc swelling. Results The mean age of included patients was 56.5 (standard deviation (SD) ± 14.85) years with a mean follow-up duration of 216 days. Thinning of pRNFL (mean: 66.26, SD ± 31.80 µm) and mGCL (mean volume: 0.27 mm3, SD ± 0.09) were observed in either group during follow-up, the mINL volume showed no thinning with 0.39 ± 0.05 mm3. The mean decrease in visual acuity was 4.13 (SD ± 14.27) ETDRS letters with a strong correlation between mGCL thickness and visual acuity (rho 0.74, p < 0.001). Conclusion After resolution of acute optic disc swelling, atrophy of pRNFL and mGCL became apparent in all cases of diabetic papillopathy and diabetic NAION, with preservation of mINL volumes. Analysis of OCT did not provide a clear diagnostic distinction between both entities. We suggest a diagnostic overlay with the degree of pRNFL and mGCL atrophy of prognostic relevance for poor visual acuity independent of the semantics of terminology.

BackgroundOptical coherence tomography (OCT) is a rapid and painless way to provide a record of the optic disc structure. Though not specific, it can identify swollen optic discs. We determined the impact of OCT prior to referral on the pathway for managing suspected papilloedema.MethodsAudit of adults referred from the Western Eye Hospital to St Mary’s Hospital with suspected papilloedema was performed between 1/1/17 and 16/5/17. A follow-up re-audit was performed from 1/6/17 to 31/8/17 following implementation of OCT prior to referral.ResultsThe initial audit identified 50 patients over 136 days and the re-audit 26 patients over 92 days. In the initial audit 6/50 had OCT and 17/50 (34%) were admitted. 6/50 patients were subsequently found not to have papilloedema on fundoscopy, none of whom had OCT. 4/6 underwent unnecessary neuroimaging and lumbar puncture. 3 were admitted, equating to 18% of all admissions, for an average of 2.3 days. In the re-audit all had OCT, 6/26 (23%) were admitted and none were subsequently found not to have papilloedema.ConclusionUse of OCT prior to referral for suspected papilloedema helps to reduce unnecessary investigations.

Purpose. To report a case of bilateral choroidal neovascularization (CNV) in punctate inner choroidopathy (PIC) visualized utilizing optical coherence tomography angiography (OCT-A). Methods. Case report. Results. A 29-year-old woman presented with new visual symptoms in both eyes. Fundoscopic exam revealed bilateral multifocal, small, well-defined lesions consistent with PIC. Optical coherence tomography demonstrated subretinal fluid and retinal pigment epithelium detachments (RPEDs) in both eyes. OCT-A revealed bilateral abnormal increased flow within the RPEDs consistent with CNV. Fluorescein angiography confirmed the presence of bilateral CNV. Conclusion. CNV secondary to PIC may be identified using noninvasive optical coherence tomography angiography.

Abstract Background: The metabolic activity of retina is higher than other human tissues and is crucial to the vision. Cynomolgus macaques is widely used in ophthalmic disease research. The evaluation and comparison of macular and optic disc vascular circulation parameters between normal adult cynomolgus macaques and healthy adult humans using OCT-A can promote better use of nonhuman primate models in studies of ophthalmic vascular disease. Methods: 12 normal adult cynomolgus macaques with a mean age of 4.91±0.43 years were studied for data collection. The macula of 28 adult healthy humans (14 males and 14 females), with a mean age of 25.11±6.21 years and the optic discs of 9 adult healthy humans (4 males and 5 females) with a mean age of 28.56±6.78 years were measured. The vessel density (VD) was measured using an RTVue XR with AngioVue. The scan sizes of the macular and optic discs were 3×3 mm and 4.5×4.5 mm, respectively. Results: OCT-A can image the superficial and deep capillary plexuses and radial peripapillary capillary network. In RPC layer of the optic disc, the VD in the nasal quadrant was lower than the VD in the inferior temporal quadrant. Similarities and significant differences in VD between healthy humans and cynomolgus macaques were obtained using OCT-A. Conclusions: This study provides normal vascular parameters for adult cynomolgus macaques using OCT-A to help establish an optical parameter database for cynomolgus macaques and compare VD between healthy humans and cynomolgus macaques to promote choroid-retinopathy research. Trial registration: Current Controlled Trials NCT03692169, retrospectively registered on 26 sept 2018 Keywords: Cynomolgus macaques, Healthy humans, Vascular, Optical coherence tomography angiography (OCT-A), Vessel density (VD)
