Ophthalmic Surgery, Lasers & Imaging Retina
|January 6, 2018
Summary
Spectral-domain optical coherence tomography (SD-OCT) reveals new findings in Purtscher-like retinopathy. These imaging insights support the microvascular embolization theory behind this condition.
Area of Science:
- Ophthalmology
- Medical Imaging
Background:
- Purtscher-like retinopathy is a rare condition causing visual impairment.
- Understanding its pathophysiology is crucial for diagnosis and treatment.
Observation:
- A prospective case series involving three eyes of two patients with Purtscher-like retinopathy.
- Patients underwent biomicroscopy, fluorescein angiography (FA), and spectral-domain optical coherence tomography (SD-OCT).
Findings:
- SD-OCT identified unique hyperreflective areas in multiple retinal layers, corresponding to cotton-wool spots and hemorrhages.
- These areas resolved over time, leading to retinal thinning, consistent with histopathological data.
- FA revealed hypofluorescent spots correlating with clinical findings.
Implications:
- The observed SD-OCT features offer novel insights into Purtscher-like retinopathy.
- These findings support the microvascular embolization theory of the disease's pathophysiology.
- Advanced imaging techniques like SD-OCT enhance diagnostic capabilities for retinal conditions.

01:03Finding the Center of Gravity
4.4K
The center of gravity of a body is an imaginary point where the body's total weight is assumed to be concentrated, and the body is perfectly balanced. The center of the mass of a body is a point at which the whole of the mass of the body appears to be concentrated. If the acceleration due to gravity, g, has the same value at all points on a body, its center of gravity is identical to its center of mass. The center of gravity of homogeneous bodies such as a sphere, cube, or rectangular plate...

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.

01:13Finding Electric Potential From Electric Field
5.7K
For a system of charges, it is easy to calculate the system's potential because potential is a scalar quantity. However, in some instances where calculating the electric field is more straightforward than finding the potential, the electric field is used to calculate the system's potential. For a positive charge, the electric field is radially outward, and the potential is positive at any finite distance from the positive charge. In such an electric field, the motion away from the...

01:24Finding Volume Using Cross-Sectional Area
102
For solids whose cross-sectional areas vary in a predictable way, volume can be determined by integrating these areas along an axis perpendicular to the slices. This approach is particularly useful for polyhedral solids, where classical geometric formulas may not be immediately applicable. A tetrahedron provides a clear example of how cross-sectional integration can be applied to a three-dimensional object with continuously changing geometry.Consider a tetrahedron with height h and a base that...

Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.
