Article Abstract
Purpose: To evaluate clinical aspects of patients with the diagnosis of plateau iris (PI) or pseudoplateau iris (PPI) made by ultrasound biomicroscopy (UBM) in order to determine if there are any clinical factors that can help differentiate between these two entities.
Method: A retrospective cohort of consecutive UBM patients with the diagnosis of PI or PPI. The diagnosis of PI was based on an anteriorly positioned ciliary body that abutted the peripheral iris, a narrow (<10 degrees) or closed angle for at least 180 degrees, and the anterior portion of the iris positioned anterior to scleral spur. The diagnosis of PPI was similar to plateau except that large or a cluster of small cysts had to be present in the iridociliary sulcus.
Results: There were a total of 76 patients (29% male), 21 with PPI and 55 with PI. Patients with PPI were more likely to be male (p = 0.005), slightly younger (51.5 (SD 10.7) vs 57.9 (10.2) p = 0.0190), have a "bumpy" peripheral iris appearance (p = 0.003), have greater trabecular meshwork pigmentation (2.0 (0.7) vs 1.3 (0.6) p = 0.004) and have fewer clock hours of gonioscopic angle closure versus plateau iris patients (5.1 (4.3) vs 9.2 (4.2) p = 0.0009). Spherical equivalent was not significantly different between groups (0.50D (1.69) PPI vs 1.33D (2.42) PI; p = 0.187).
Conclusions: In patients being referred to a UBM clinic for evaluation of angle-closure mechanism, younger males with a bumpy peripheral iris have a higher likelihood of having a diagnosis of pseudoplateau iris. However, clinical factors do not appear to discriminate well between PPI and PI. UBM is extremely helpful in confirming underlying mechanism and guiding therapy.

Loss values of style transfer from UBM to AS-OCT images for plateau iris classification.

Ultrasound biomicroscopy (UBM) is the standard for diagnosing plateau iris, but its limited accessibility in routine clinical settings presents challenges. While anterior segment optical coherence tomography (AS-OCT) is more convenient, its effectiveness in detecting plateau iris is limited. Previous research has demonstrated that combining UBM and AS-OCT image pairs through neural style transfer has improved classification accuracy.

Article Synopsis
- An environmental bacterium, previously known as a rare pathogen, is seldom linked to human infections but has been associated with cases like sepsis and meningitis.
- A 67-year-old woman with several health issues developed complications after surgery for a broken leg, leading to skin and bone infections caused by this bacterium.
- The case highlights that while serious infections from this bacterium are rare, they can affect immunocompromised patients, marking the first documented instance of osteitis and skin necrosis from this organism.
Potential utility of anterior segment optical coherence tomography and biometry in differentiating plateau iris configuration from pupillary block.

Article Synopsis
- Angle closure glaucoma primarily affects older individuals but can also impact younger people, making it crucial to identify its causes for effective treatment planning.
- The study investigates the use of anterior segment optical coherence tomography (ASOCT) and optical biometry to differentiate between plateau iris configuration (PIC) and pupillary block (PB) in young adults with primary angle closure disease.
- Findings indicate that while both PIC and PB have parameters smaller than normal eyes, no single measurement distinctly separates PB from PIC; however, axial length and relative lens vault offer some ability to make this distinction.

Article Synopsis
- - The study aimed to create and validate a deep learning model called CMD-Net that can effectively identify and classify mechanisms of angle-closure (AC) in eye images obtained from anterior segment optical coherence tomography (AS-OCT).
- - Researchers analyzed 11,035 AS-OCT images from 1,455 participants, comparing the deep learning model's performance against human ophthalmologists in classifying AC mechanisms, ultimately showing CMD-Net's superior accuracy with mean AUC scores of up to 0.988.
- - Findings indicate that CMD-Net may serve as a reliable tool for classifying AC mechanisms in clinical settings, although further testing is necessary to confirm its effectiveness.
