Summary
Optos wide-angle imaging can create a concerning nose artifact, mimicking a choroidal tumor. Proper patient positioning is crucial to avoid misdiagnosis in retinal imaging.
Area of Science:
- Ophthalmology
- Medical Imaging
Background:
- Wide-angle imaging devices like Optos offer extensive retinal views.
- Accurate interpretation of retinal images is vital for diagnosing ocular conditions.
Observation:
- A case report details an 11-year-old girl initially suspected of having a choroidal tumor.
- The suspicious lesion was identified via Optos wide-angle imaging.
- Subsequent examinations, including funduscopy and B-scan ultrasonography, did not reveal any mass.
Findings:
- The apparent choroidal tumor on Optos imaging was identified as a nose artifact.
- This artifact resulted from improper patient positioning during the wide-angle scan.
Implications:
- Wide-angle imaging artifacts can lead to misdiagnosis and unnecessary patient anxiety.
- Emphasizes the importance of meticulous patient positioning and image review in Optos imaging.
- Highlights the need for correlation with other diagnostic methods to confirm findings.

01:24Nose and Nasal Cavity
12.1K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

02:20Correlations
36.4K
Correlation means that there is a relationship between two or more variables (such as ice cream consumption and crime), but this relationship does not necessarily imply cause and effect. When two variables are correlated, it simply means that as one variable changes, so does the other. We can measure correlation by calculating a statistic known as a correlation coefficient. A correlation coefficient is a number from -1 to +1 that indicates the strength and direction of the relationship between...

10.4K
The nucleolus is the most prominent substructure of the nucleus. When it was first discovered, it was considered to be an isolated organelle that forms fibrils and granules. In 1931, the relationship between the nucleolus and chromosomes was first described by Heitz. He observed that the appearance and size of nucleolus varies depending on the stage of the cell cycle. He also noticed constricted regions on different chromosomes clustered together at definite cell cycle stages. These regions,...

The rate of reaction is the change in the amount of a reactant or product per unit time. Reaction rates are therefore determined by measuring the time dependence of some property that can be related to reactant or product amounts. Rates of reactions that consume or produce gaseous substances, for example, are conveniently determined by measuring changes in volume or pressure.
The mathematical representation of the change in the concentration of reactants and products, over time, is the rate...

27.5K
The fossil record documents only a small fraction of all organisms that have ever inhabited Earth. Fossilization is a rare process, and most organisms never become fossils. Moreover, the fossil record only exhibits fossils that have been discovered. Nevertheless, sedimentary rock fossils of long-lived, abundant, hard-bodied organisms dominate the fossil record. These fossils offer valuable information, such as an organism's physical form, behavior, and age. Studying the fossil record helps...
