In real life, low-energy SRT was associated with a reduced anti-VEGF injection frequency through year 3. However, due to an observed visual acuity reduction and remarkable number of MVAs, a close follow-up of these patients is recommended. The real-life use, optimal treatment schedule and dose should be rediscussed critically.

  To apply deep learning technology to develop an artificial intelligence (AI) system that can identify vision-threatening conditions in high myopia patients based on optical coherence tomography (OCT) macular images.
 
  In this cross-sectional, prospective study, a total of 5505 qualified OCT macular images obtained from 1048 high myopia patients admitted to Zhongshan Ophthalmic Centre (ZOC) from 2012 to 2017 were selected for the development of the AI system. The independent test dataset included 412 images obtained from 91 high myopia patients recruited at ZOC from January 2019 to May 2019. We adopted the InceptionResnetV2 architecture to train four independent convolutional neural network (CNN) models to identify the following four vision-threatening conditions in high myopia retinoschisis, macular hole, retinal detachment and pathological myopic choroidal neovascularisation. Focal Loss was used to address class imbalance, and optimal operating thresholds were determined according to the Youden Index.
 
  In the independent test dataset, the areas under the receiver operating characteristic curves were high for all conditions (0.961 to 0.999). Our AI system achieved sensitivities equal to or even better than those of retina specialists as well as high specificities (greater than 90%). Moreover, our AI system provided a transparent and interpretable diagnosis with heatmaps.
 
  We used OCT macular images for the development of CNN models to identify vision-threatening conditions in high myopia patients. Our models achieved reliable sensitivities and high specificities, comparable to those of retina specialists and may be applied for large-scale high myopia screening and patient follow-up.

  To analyse the long-term anatomic and visual outcomes of patients with peripapillary pachychoroid syndrome (PPS), a recently described entity in the pachychoroid disease spectrum.
 
  This study retrospectively included patients from several retina centres worldwide. Visual acuity (VA), retinal thickness and choroidal thickness at baseline, 6 months and final follow-up were assessed. Temporal trends in VA and anatomic characteristics were evaluated. Visual and anatomic outcomes in eyes that were observed versus those that were treated were analysed.
 
  Fifty-six eyes of 35 patients were included with mean follow-up of 27±17 months. Median VA was 20/36 at baseline and remained stable through follow-up (p=0.77). Retinal thickness significantly decreased subfoveally (p=0.012), 1.5 mm nasal to the fovea (p=0.002) and 3.0 mm nasal to the fovea (p=0.0035) corresponding to areas of increased thickening at baseline. Choroidal thickness significantly decreased subfoveally (p=0.0030) and 1.5 mm nasal to the fovea (p=0.0030). Forty-three eyes were treated with modalities including antivascular endothelial growth factor injection, photodynamic therapy, and others. VA remained stable in treated eyes over follow-up (p=0.67). An isolated peripapillary fluid pocket in the outer nuclear layer was characteristic of PPS.
 
  Patients with PPS experienced decreased retinal oedema and decreased choroidal thickening throughout the course of disease. While some patients experienced visual decline, the overall visual outcome was relatively favourable and independent of trends in retinal or choroidal thickening.

  To compare the efficacy of diabetic retinal neovascularisation (NV) detection using the widefield swept-source optical coherence tomography angiography (WF SS-OCTA) vitreoretinal interface (VRI) Angio slab and SS-OCT VRI Structure slab.
 
  A prospective, observational study was performed at Massachusetts Eye and Ear from January 2019 to June 2020. Patients with proliferative diabetic retinopathy (PDR), patients with non-proliferative diabetic retinopathy and patients with diabetes but without diabetic retinopathy were included. All patients were imaged with WF SS-OCTA using the 12×12 mm Angio scan protocol centred on the fovea and optic disc. The en-face SS-OCTA VRI Angio slab and SS-OCT VRI Structure slab were evaluated for the presence or absence of NV. SS-OCTA B-scan was used to classify NV according to cross-sectional morphology (forward, tabletop or flat).  https://www.selleckchem.com/products/alpha-conotoxin-gi.html  All statistical analyses were performed using SPSS V.26.0.
 
  One hundred and forty-two eyes of 89 participants were included in the study. VRI Angio detected NV at higher rates compared with VRI Structure (p<0.05). Combining VRI Angio and Structure improved detection rates compared with VRI Angio alone (p<0.05). Due to segmentation errors of the internal limiting membrane, NV with flat morphological classification had lower rates of detection on VRI Angio compared with NV with forward and tabletop morphology (p<0.05).
 
  WF SS-OCTA 12×12 mm VRI Angio and SS-OCT VRI Structure imaging centred on the fovea and optic disc detected NV with high sensitivity and low false positives. The VRI slab may be useful to diagnose and monitor PDR in clinical practice.
