AI Article Synopsis

  • This case report evaluates a new multicolored-spot reflection topographer for imaging the corneal surface, comparing it with four established imaging systems.
  • A 17-year-old girl with chronic herpetic keratitis in her left eye was studied, revealing that traditional systems struggled to accurately image her condition due to various limitations.
  • The findings suggest that the novel topographer could be a reliable option for corneal imaging in challenging cases, highlighting its potential for improving clinical outcomes in ophthalmology.

Article Abstract

This case report aims to evaluate safety, efficacy and feasibility of anterior surface imaging by a novel point-source reflection topographer, in comparison to four other corneal imaging modalities. A 17-year-old female patient, clinically diagnosed with chronic herpetic keratitis in her left eye was imaged by a novel multicolored-spot reflection topography system. We comparatively investigated elevation and curvature maps between the novel topographer and established Placido disk topography and Scheimpflug tomography systems. Pachymetry maps were compared between the Scheimpflug system and anterior-segment optical coherence tomography system. The Placido system failed to properly register the abnormal anterior surface due to incomplete mire registration, while the Scheimpflug topometry device imaged the anterior surface properly, but not the posterior (due to media opacity), and thus pachymetry was highly irregular and erroneous in this case. Imaging of corneas infected with herpes simplex virus keratitis has been rare; we have not identified any such documentation in the peer review literature in the last 10 years. This novel multicolored-spot reflection topography imaging may offer successful corneal imaging in cases where established clinical topography systems may fail to produce accurate reconstruction of the corneal shape. This is an important case demonstrating exceptional clinical feasibility in such rare cases offered by a newly introduced technology in ophthalmic imaging.

Some studies have confirmed that pathogens can cause infection through bacterial cultures on the surface of infectious keloids. However, further exploration of the comparison between infectious and non-infectious keloids and the bacterial flora of infectious foci is lacking. To investigate the differential flora of purulent secretions on the surface of infectious keloids compared to non-infectious keloids and to determine the microbial composition within the infectious foci.

Background And Objectives: Härtel triangle provides surface landmarks for locating the foramen ovale (FO) when performing trigeminal nerve percutaneous procedures. Although widely adopted in clinical practice, there is no report that these landmarks have ever been formally validated through modern imaging techniques. Here we aim to validate Härtel anatomical landmarks using computed tomography scans and propose technical considerations for percutaneous trigeminal procedures.

Background: Adolescent idiopathic scoliosis (AIS) is characterized by an asymmetrical formation of the spine and ribcage. Recent work provides evidence of asymmetrical (right versus left side) paraspinal muscle size, composition, and activation amplitude in adolescents with AIS. Each of these factors influences muscle force generation.

Background: To evaluate the biosafety, reduction in anterior capsule opacification, and fluctuation in intraocular pressure (IOP) of a new phakic refractive lens (PRL) with a sinusoidal drainage groove design.

Methods: This self-controlled experiment was performed on eight eyes of four rabbits. Each rabbit was implanted with a sinusoidal PRL (PRL-S5) in the right eye and a conventional posterior chamber PRL (PC-PRL) in the left eye.

Purpose: To evaluate the effect of aging and bleaching on the physico-mechanical properties of the different filled resin composites.

Methods: Samples of resin composites [Arabesk (A), G-aenial Anterior (G), i-LIGHT N (I) and Palfique Estelite Paste (P) \ were first divided into two subgroups. Thermal aging was applied to half of the samples.
