Summary
Optical coherence tomography (OCT) can detect early signs of neurological and systemic diseases through retinal changes. This imaging technique aids in early diagnosis, differentiation of abnormalities, and monitoring treatment effectiveness.
Area of Science:
- Ophthalmology
- Neurology
- Systemic Diseases
- Medical Imaging
Background:
- Advancements in imaging technology have significantly improved the understanding of ocular diseases.
- Optical coherence tomography (OCT) is a key imaging modality in ophthalmology.
Purpose of the Study:
- To review and summarize optical coherence tomography (OCT) findings associated with various systemic conditions.
- To highlight the diagnostic and prognostic value of OCT in systemic diseases.
Main Methods:
- Systematic literature search of Medline/PubMed database up to April 2015.
- Inclusion of English articles.
- Search terms included specific neurological, hematological, oncological, and toxicological conditions along with OCT.
Main Results:
- Inner retinal thinning identified as an early indicator of neurological diseases.
- Outer retinal damage observed in cancer-related retinopathy and drug toxicity.
- OCT findings are crucial for early diagnosis, treatment assessment, and follow-up across diverse systemic diseases.
Conclusions:
- OCT findings are valuable for predicting disease probability and early diagnosis.
- OCT assists in differentiating healthy from unhealthy ocular tissue.
- OCT is effective in assessing therapeutic intervention outcomes in systemic diseases.

9.7K
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
1.5K
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...
