Aim: To evaluate the efficacy of intravitreal injection of anti-vascular endothelial growth factor (anti-VEGF), photodynamic therapy (PDT), and laser treatment (LT) for anatomical and functional improvement in myopic choroidal neovascularization (mCNV) patients.
Methods: Two researchers independently searched PubMed, Cochrane Library, Web of Science, and other databases to screen studies comparing best-corrected vision acuity (BCVA) and foveal center thickness (FCT) changes after mCNV treatment. Post-treatment chorioretinal atrophy (CRA) is a secondary outcome indicator. The retrieval time limit is from the database construction to January 30, 2023.
Results: A total of 1072 eyes in 16 articles were included. In the RCTs, intravitreal bevacizumab (IVB) and intravitreal ranibizumab (IVR) were superior to PDT (MD=0.18, 95%CI: 0.02, 0.40, MD=0.18, 95%CI: 0.01, 0.42) in improving BCVA of mCNV patients (<0.05). The relative effectiveness in improving BCVA, from high to low, appeared to be IVR, intravitreal aflibercept (IVA), IVB, LT, PDT, and sham first followed by IVA (Sham/IVA). While improving the FCT from high to low was IVA, IVR, IVB, PDT. In retrospective studies, the results of BCVA after long-term treatment showed that all the therapeutic effects from high to low was IVA, intravitreal conbercept (IVC), IVR, IVB, IVB/IVR, PDT with IVB/IVR, PDT. The effect of improving FCT was IVA, IVR, IVC, PDT, and IVB from high to low. And in the effects of improving CRA, the IVB appeared to be higher than IVR, while the PDT was the smallest, but none of the differences in the results were statistically significant.
Conclusion: Anti-VEGF has the best effect on long-term vision improvement in mCNV patients, using IVB or IVR alone to treat mCNV may be better than IVB or IVR combined with PDT. There is no significant difference in the improvement of visual acuity, macular edema, and CRA in mCNV patients treated with any different anti-VEGF drugs.

Effects of computer-generated patterns with different temporal and spatial frequencies on choroidal thickness, retinal dopamine and candidate genes in chickens wearing lenses.

Section of Neurobiology of the Eye, Ophthalmic Research Institute, University of Tübingen, Tübingen, Germany.
Purpose: Changes in choroidal thickness (ChT) are proposed to predict myopia development but evidence is mixed. We investigated time courses of choroidal responses, following different types of dynamic artificial stimulation in chicks with and without spectacle lenses, as well as changes in retinal dopamine metabolism and expression of candidate genes.
Methods: Chicks were kept in an arena surrounded by computer monitors presenting dynamic checkerboard fields of small, medium and large size.

We investigated the mechanism of action of atropine in myopia control by examining its effect on choroidal hemodynamics. Blood flow was evaluated using indocyanine green (ICG) fluorescence and molecular variation during the development of form-deprivation myopia (FDM) and atropine treatment in guinea pigs. Guinea pigs were divided randomly into the normal control (NC), FDM, and FDM + 1% atropine (ATR) groups, and evaluated by spherical equivalent refractive error (SE) and axial length (AL).

Background: Several nutrients have been found to be associated with the prevalence of myopia, and the role of dietary patterns in influencing myopia risk has recently garnered significant attention. We aim to explore the relationship between the Dietary Inflammatory Index (DII) and refractive status in adolescents.
Methods: Data from 7,331 participants were analyzed from the 2005-2008 US National Health and Nutrition Examination Survey (NHANES).

Background: The eyeball axial length (AL) is an important biological indicator of myopia, which has been widely studied. However, little research has been conducted on the relationship between eye shape and fundus structural changes in myopia. This study aimed to analyze the relationship between the shape of the posterior pole of the eye, and choroidal characteristics by comparing with the relationship between AL and choroidal characteristics.

Purpose: To explore the relationship between peripapillary atrophy (PPA) and diabetic retinopathy (DR), and to uncover potential mechanisms using swept-source optical coherence tomography (SS-OCT) angiography.
Methods: This cross-sectional study included 845 patients with type 2 diabetes (T2DM), who underwent detailed systemic and ophthalmic evaluations. A state-of-the-art deep learning method was employed to precisely identify the parapapillary beta and gamma zones.
