Purpose: to report optical coherence tomography angiography findings in syphilitic outer retinopathy, a singular clinical manifestation of ocular syphilis.
Methods: case report.
Results: Multimodal imaging including optical coherence tomography angiography was performed in a patient presenting syphilitic outer retinopathy. Optical coherence tomography angiography showed multifocal areas of flow deficit at the choriocapillaris level at presentation, whereas no vascular abnormalities were observed at deep and superficial capillary plexuses. After a one-year follow-up period, choriocapillaris flow showed an almost complete recovery.
Conclusion: Syphilitic outer retinopathy represents a singular clinical manifestation of ocular syphilis. The almost complete recovery of initial ischemic changes at one year of follow-up suggests that this entity may have a good prognosis with timely and proper antibiotic treatment.

Time-resolved coherent Raman spectroscopy (CRS) is a powerful non-linear optical technique for quantitative, in-situ analysis of chemically reacting flows, offering unparalleled accuracy and exceptional spatiotemporal resolution. Its application to large polyatomic molecules, crucial for understanding reaction dynamics, has thus far been limited by the complexity of their rotational-vibrational Raman spectra. Progress in developing comprehensive spectral codes for these molecules, a longstanding goal, has been hindered by prohibitively long computation times required for their spectral synthesis.

Objectives: To use finite element (FE) modeling and in vivo optical coherence tomography (OCT) imaging to explore the effect of ciliary muscle traction on optic nerve head (ONH) deformation during accommodation.
Methods: We developed a FE model to mimic the ciliary muscle traction during accommodation, and varied the stiffness of the sclera, choroid, Bruch's membrane (BM), prelaminar neural tissue and lamina cribrosa (LC) to assess their effects on accommodation-induced ONH strains. To validate the FE model, OCT images of the right eyes' ONHs from 20 subjects (25 ± 1.

Background: Idiopathic intracranial hypertension (IIH) is a condition where the pressure of the cerebrospinal fluid in the brain increases without a known cause. It typically affects adults but can also occur in adolescents and children, although it is less common. Numerous elements, including coagulopathy, have been documented in previous cases as potential etiological factors of IIH.

The morphology and thickness of the retinal layers are valuable biomarkers for retinal health and development. The retinal layers in mice are similar to those in humans; thus, a mouse is appropriate for studying the retina. The objectives of this systematic review were: (1) to describe normal retinal morphology quantitatively using retinal layer thickness measured from birth to age 6 months in healthy mice; and (2) to describe morphological changes in physiological retinal development over time using the longitudinal (in vivo) and cross-sectional (ex vivo) data from the included studies.

The role of prolactin in sleep regulation has been the subject of extensive research over the past 50 years, resulting in the identification of multiple, disparate functions for the hormone. Prolactin demonstrated a characteristic circadian release pattern with elevation during dark and diminution during light. High prolactin levels were linked to non-rapid eye movement sleep and electroencephalogram delta activity in humans.
