Summary
Cat scratch disease (CSD) can cause neuroretinitis, a rare condition affecting one eye. Early diagnosis is crucial for patients with sudden vision changes, distinguishing it from optic neuritis.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Neuro-ophthalmology
Background:
- Neuroretinitis is an optic neuropathy often linked to Bartonella henselae (cat scratch disease).
- It presents with optic nerve swelling and may show a macular star, retinal thickening, and subretinal fluid on OCT.
- While rare, CSD neuroretinitis must be considered in unilateral visual disturbances.

6.2K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

01:25Glaucoma: Overview
674
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...
