Abstract
We conducted a systematic review and meta-analysis to assess the association between optical coherence tomography angiography (OCTA) parameters and acute coronary syndrome (ACS). Two independent reviewers searched the electronic databases (MEDLINE (Medical Literature Analysis and Retrieval System Online), Scopus, Embase (Excerpta Medica Database), Cochrane Library, ClinicalTrials.gov, and World Health Organization International Clinical Trials Registry Platform) from inception until April 2023. According to the inclusion criteria of this review, eligible were observational studies, randomized control trials, and registry/database studies that included the eyes of adult ACS patients and assessed OCTA parameters within the macula. The pooled standardized mean differences (SMD) between patients diagnosed with ACS and healthy controls with a confidence interval (CI) of 95% were calculated using the Hartung-Knapp-Sidik-Jonkman random-effects method. The heterogeneity was assessed by I2 and the Cochran Q and a random effects model was applied. Seven studies were eligible and included in our systematic review (n = 898), of which three were included in the meta-analysis (n = 341). The pooled SMD in the superficial vascular plexus (SVP), deep vascular plexus (DVP), and foveal avascular zone (FAZ) were -0.46 (95% CI: -0.94 to 0.01, p = 0.05, I2 = 0%, three studies), -0.10 (95% CI: -3.20 to 3.00, p = 0.75, I2 = 67%, two studies), and 0.43 (95% CI: -1.22 to 2.09, p = 0.38, I2 = 92%, three studies), respectively. Our findings suggest that there are no differences in OCTA metrics between ACS patients and healthy individuals.

Abstract
BACKGROUND AND AIMS The aim of this study was to evaluate changes in vascular density in the macula after pars plana vitrectomy for idiopathic macular hole (IMD) with macular peeling and flap. METHODS A prospective study of 35 eyes in 34 patients who had undergone standard surgery. Evaluated parameters were best-corrected visual acuity (BCVA), intraocular pressure (IOP), central macular thickness (CRT), macular volume (TMV) and vascular density of the superficial and deep capillary plexus. The follow-up period was one year. RESULTS We divided the total group into two: temporal and circular flap and total group. We compared the values after surgery with the preoperative values. In the total group, BCVA increased from 48.38 to 71.44 letters (P≤0.05). IOP changed from 15.24 to 14.76 mmHg (P>0.05). CRT decreased from 432.27 to 323.64 µm (P≤0.05). TMV changed from 0.26 to 0.25 mm3 (P>0.05). The vascular density of the superficial plexus decreased from 32 to 28% (P≤0.05). The intercapillary space of the superficial plexus increased from 68 to 72% (P≤0.05). The vascular density of the deep plexus increased from 17 to 23%. The intercapillary space of the deep vascular plexus decreased from 83 to 77%. Changes in vascular density and intercapillary space of the deep plexus were statistically significant for certain months after operations (P≤0.05). There were no significant differences between subgroups. CONCLUSION The superficial plexus vascular density is almost the same in the temporal flap and in the foveal-sparing flap is decreased, and the deep plexus vascular density increased statistically significantly during the follow-up period after surgery.

Abstract
Background Hereditary spastic paraplegia (HSP) is characterized by progressive degeneration of distal axons in the long corticospinal tracts. Loss of retinal cells and microvascular networks has neither been suspected nor investigated. We concurrently examined the retinal microvasculature and retinal layer morphology in patients with HSP to assess whether retinal features may portray disease and its progression. Methods Fifteen patients with HSP and 30 healthy controls were included in this cross-sectional case-control study. Disease severity was assessed with the Spastic Paraplegia Rating Scale (SPRS). Severity of ataxia was determined by the Scale for the Assessment and Rating of Ataxia (SARA). Retinal microvasculature was measured by means of optical coherence tomography angiography (OCT-A) and morphology of retinal layers using structural OCT. Mixed-effects models were applied for data analysis. Results HSP patients showed significantly reduced vessel density of the superficial vascular plexus (SVP), reduced ganglion cell layer (GCL) volume, reduced inner plexiform layer (IPL) volume and reduced temporal-inferior peripapillary retinal nerve fiber layer (pRNFL) thickness versus healthy controls. GCL volume reduction correlated significantly with the worsening of visual acuity and higher SARA scores. Conclusions These findings demonstrate that, in HSP both cells and vascular networks of the retina are compromised. Assessment of the retinal GCL, IPL and SVP may aid in diagnosis and monitoring of disease progression as well as provide novel structural outcome measures for clinical trials.

Abstract
A 5-year-old Caucasian male with a history nonaccidental injury (NAI) at age 1 presented with new onset no light perception in the left eye due to a closed funnel retinal detachment. The right eye showed optic nerve pallor, peripheral vascular attenuation, and leakage. Optical coherence tomography angiography (OCTA) revealed significant parafoveal attenuation of the superficial vascular plexus, intermediate capillary plexus, and the deep capillary plexus. This correlated with inner and middle retinal layer thinning temporal to the fovea and preservation of the ellipsoid zone. The peripapillary vascular plexus was preserved. Laser photocoagulation was performed to the nonperfused peripheral retina and intravitreal bevacizumab was injected. OCTA may be used in patients with NAI to characterize macular ischemia changes. Attenuation of the superficial, intermediate, and deep capillary plexuses in our patient may represent chronic ischemic retinal changes that arise from traumatic injury to the vitreoretinal interface and inner retina in NAI.

Abstract
Objectives: The aim of this study was to evaluate the relationship between optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) parameters in a healthy population and to detect any changes that occur with age. Methods: A total of 100 healthy participants were included in this prospective, observational, and comparative study. The participants were categorized in 4 groups according to age: Group 1: 21-30 years, Group 2: 31-40 years, Group 3: 41-50 years, Group 4: 51-60 years of age. Mean macular thickness, retinal nerve fiber layer (RNFL), ganglion cell inner plexiform layer (GC-IPL), and the choroidal thickness (ChT), vessel density (VD), perfusion density (PD), foveal avascular zone (FAZ), and parapapillary perfusion density parameters were recorded and analyzed. Results: In comparisons between groups, no significant difference in OCTA parameters was observed. There were inverse correlations between the outer VD, PD, and intraocular pressure (IOP) (r= -0.307, p=0.006 and r= -0.284, p=0.011, respectively). The correlation between parapapillary perfusion density and IOP was close to being significant (r= -0.213, p=0.059). There were significant relationships between OCTA parameters and macular, RNFL, and GC-IPL thickness. No significant relationship between ChT and OCTA parameters was seen. Conclusion: The size and characteristics of superficial VD, PD, parapapillary perfusion density, and FAZ were determined in a population with standardized demographic and ocular clinical features, and the relationship between these parameters and retinal layers was established.
