Objective: To evaluate neointimal proliferation following placement of a new drug-eluting stent (BUMA) by optical coherence tomography (OCT).
Methods: Twenty-two patients with coronary artery disease were randomized into BUMA group (n=15) and Endeavor group (n=7) and underwent OCT imaging after 9 months of stent implantation.
Results: The neointima hyperplasia (NIH) thickness in BUMA group were significantly smaller than that in endeavor group (0.220-/+0.140 mm vs 0.269-/+0.207 mm, P<0.001), and the uncovered Struts were significantly lower in BUMA group than in Endeavor group (5.65% vs 6.56%, P<0.0001). The luminal late loss in BUMA group was also significantly lower (34.87-/+11.50 vs 40.82-/+18.53, P=0.025).
Conclusion: BUMA stent is safe and effective for treatment of coronary artery disease.

Background: An idiopathic macular hole (IMH) is a foveal opening in the neurosensory retina caused by perifoveal vitreomacular traction and detachment. IMH prevalence varies considerably across populations, highlighting a need for further investigation, especially in underrepresented groups such as Hispanics.
Methods: This retrospective, descriptive, cross-sectional study analyzed IMH prevalence in a Hispanic population over four years.

The choroid, a critical vascular layer beneath the retina, is essential for maintaining retinal function and monitoring chorioretinal disorders. Existing imaging methods, such as indocyanine green angiography (ICGA) and optical coherence tomography (OCT), face significant limitations, including contrast agent requirements, restricted field of view (FOV), and high costs, limiting accessibility. To address these challenges, we developed a nonmydriatic, contrast agent-free fundus camera utilizing transcranial near-infrared (NIR) illumination.

Conventional scanned optical coherence tomography (OCT) suffers from the frame rate/resolution tradeoff, whereby increasing image resolution leads to decreases in the maximum achievable frame rate. To overcome this limitation, we propose two variants of machine learning (ML)-based adaptive scanning approaches: one using a ConvLSTM-based sequential prediction model and another leveraging a temporal attention unit (TAU)-based parallel prediction model for scene dynamics prediction. These models are integrated with a kinodynamic path planner based on the clustered traveling salesperson problem to create two versions of ML-based adaptive scanning pipelines.

Optical coherence tomography angiography (OCTA) offers unparalleled capabilities for non-invasive detection of vessels. However, the lack of accurate models for light-tissue interaction in OCTA jeopardizes the development of the techniques to further extract quantitative information from the measurements. In this manuscript, we propose a Monte Carlo (MC)-based simulation method to precisely describe the signal formation of OCTA based on the fundamental theory of light-tissue interactions.

The motion of the trabecular meshwork (TM) facilitates the aqueous drainage from the anterior chamber to the venous system, thereby maintaining normal intraocular pressure. As such, characterizing the TM motion is valuable for assessing the functionality of the aqueous outflow system, as demonstrated by previous phase-sensitive optical coherence tomography (OCT) studies. Current methods typically acquire motion from a single cross-sectional plane along the circumference of the anterior chamber.
