Summary
Spectral domain optical coherence tomography (Sd-OCT) identified unique retinal changes in two patients with vision loss due to syphilis (lues). These changes resolved with treatment, highlighting Sd-OCT
Area of Science:
- Ophthalmology
- Medical Imaging
- Infectious Diseases
Background:
- Unclear visual loss can present diagnostic challenges, necessitating advanced imaging techniques.
- Vitreous clouding can obscure retinal details, complicating diagnosis.
- Syphilis (lues) can manifest with ocular inflammatory conditions like uveitis.
Observation:
- Two patients presented with unexplained visual loss and vitreous clouding.
- Diagnostic workup included spectral domain optical coherence tomography (Sd-OCT) and fluorescein angiography (FLA).
- Characteristic FLA findings suggested papillitis and vasculitis.
Findings:
- Novel morphological changes in the photoreceptor layer and pigment epithelium were observed using Sd-OCT.
- These Sd-OCT findings were previously undescribed in the context of ocular syphilis.
- Resolution of these unique Sd-OCT changes correlated with successful treatment of lues.
Implications:
- Sd-OCT is a valuable tool for diagnosing uveitis, particularly in cases of ocular syphilis.
- The described Sd-OCT findings may serve as specific biomarkers for syphilitic ocular inflammation.
- Early and accurate diagnosis using advanced imaging can lead to timely treatment and improved visual outcomes.

01:02Ultraviolet and Visible (UV–Vis) Spectroscopy: Overview
Ultraviolet–visible (UV–visible or UV–Vis) spectroscopy is an analytical technique that investigates the interaction between matter and UV–Vis light within the electromagnetic spectrum. This method is widely used for its versatility, simplicity, and relatively quick data acquisition, making it valuable for both qualitative and quantitative analysis. When UV–Vis radiation passes through a material, molecules absorb light depending on the energy required for electronic transitions. As a result...
01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:30UV–Vis Spectrum
When light passes through a substance, a portion of the light is absorbed while the remaining light is reflected or transmitted. If the molecule absorbs light between the wavelengths of 180–400 nm range, the UV spectrum is obtained, and if it absorbs light in the 400–780 nm wavelength range, the visible spectrum is obtained.
The UV–Vis spectrum of a molecule is the plot of its absorbance versus wavelength. The plot is drawn by taking molar absorptivity (ε) or log ε on the y-axis (ordinate)...

01:27Open Angle Glaucoma: Treatment
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
01:14UV–Vis Spectrometers
The absorbance of UV and visible (UV–visible) radiations is measured using a UV–visible spectrophotometer. Deuterium lamps, which emit UV radiation, and tungsten lamps, which produce radiation in the visible region, are used as light sources in UV–visible spectrophotometers. A monochromator or prism is used for diffraction grating, i.e., to split the incoming radiation into different wavelengths. A system of slits is used to focus the desired wavelength on the sample cell. Samples for...
