Summary: This study aimed to understand the pathogenesis of adult-onset foveomacular vitelliform dystrophy (AFVD) by assessing its pseudohypopyon stage (PHS). Results showed that the PHS in AFVD is often characterized by lateral liquefaction, unlike the altitudinal pattern seen in BVMD. Age, lesion size, or pathogenesis pathways may underlie the different PHS patterns in AFVD and BVMD.

Summary: This study characterized the evolution of acquired vitelliform lesions (AVLs) in patients with age-related macular degeneration (AMD) using optical coherence tomography (OCT) technology and ImageJ software. The results showed increased thickness of the retinal pigment epithelium (RPE) in the central quadrant and decreased thickness of the outer nuclear layer (ONL) in the vitelliform group compared to the control group. The impact of AVLs on the retina was associated with the presence of a continuous external limiting membrane (ELM) and ellipsoid zone (EZ).

Summary: This article introduces a method to extract the photoacoustic (PA) signal from the contrast reduction in the interference spectrum obtained from spectral domain optical coherence tomography (SDOCT). The method utilizes the specular reflection on the water surface to achieve all-optical detection in a non-contact manner. By analyzing the phase changes in the interference spectrum induced by water surface vibration, the method enables quantification of the interference contrast reduction for PA imaging.

Summary: With the advancement of light source technology, the A-line imaging rate of SS-OCT has significantly increased in the past three decades. However, the bandwidths of data acquisition, transfer, and storage have become major limitations in modern SS-OCT system design. To address this, a novel design paradigm is proposed where the sub-sampling pattern for interferogram acquisition is jointly optimized with the reconstruction algorithm. This method achieves high data compression ratios without impairing image quality, making it a potential solution for the data issue in SS-OCT.

Summary: Non-exudative macular and choroidal neovascularization (MNV and CNV) refers to treatment-naive type 1 neovascularization without exudation. This entity was first reported in the late 90s and has been increasingly recognized with advanced retinal imaging. However, there is a lack of consensus regarding the definition and clinical management. This review discusses the prevalence, imaging features, clinical course, and response to treatment of non-exudative MNV and CNV, providing key insights and proposing a new theory about their origin and course.

Summary: This study investigated the association between nascent geographic atrophy (GA) and the development of exudative type 3 macular neovascularization (MNV) in patients with age-related macular degeneration (AMD). The results showed that 22.7% of the patients had nascent GA preceding exudative type 3 MNV. Therefore, the detection of nascent GA in AMD patients may require closer surveillance to identify early exudative type 3 MNV warranting treatment.

Summary: This study characterized a novel OCT finding called subretinal pseudocysts and explored its clinical outcome. The results showed that subretinal pseudocysts usually occur in the presence of subretinal fluid and may be transient alterations within the photoreceptor outer segments and retinal pigment epithelium (RPE) layer. These pseudocysts were associated with photoreceptor loss and incomplete RPE definition.

Summary: This study investigated the relationship between imaging biomarkers and mesopic and dark-adapted functions in patients with treatment-naive mild diabetic retinopathy (DR) and normal visual acuity. The results showed that both rod and cone functions were affected in DR eyes, and they were associated with impairment in deep capillary plexus (DCP) and choriocapillaris (CC) flow. Normalized ellipsoid zone (EZ) reflectivity may be a valuable structural biomarker for assessing photoreceptor function in DR.

Summary: The study investigated the phenotype, variability, and penetrance of IMPG2-related maculopathy. The results showed that mono-allelic IMPG2 variants could result in haploinsufficiency manifesting as a maculopathy with variable penetrance and expressivity. Family members of patients with IMPG2-related retinitis pigmentosa may also present with vitelliform lesions. The maculopathy is usually limited to the fovea and is associated with moderate visual impairment.
