Case Reports in Ophthalmology
|April 24, 2018
Summary
Intraoral local anesthesia can rarely cause vision loss. This case highlights cilioretinal artery occlusion after dental anesthesia, emphasizing inadvertent intravascular injection as a potential cause.
Area of Science:
- Ophthalmology
- Dentistry
- Anesthesiology
Background:
- Intraoral local anesthetics are standard for dental procedures.
- Ocular complications like vision changes can occur but are typically transient.
- The exact mechanisms behind these rare complications remain unclear.
Observation:
- A 38-year-old male experienced reduced vision in his left eye five days post-dental local anesthesia.
- Clinical examination revealed optic disc swelling and a diagnosis of cilioretinal artery occlusion.
- Symptoms resolved over ten weeks, with visual acuity returning to normal.
Findings:
- This case report details a prolonged ocular complication following intraoral local anesthesia.
- Cilioretinal artery occlusion is a potential, though rare, adverse event.
- Inadvertent intravascular injection is suspected as the primary cause in this instance.
Implications:
- Highlights the importance of careful anesthetic administration techniques in dentistry.
- Suggests vigilance for prolonged visual disturbances after dental procedures.
- Underscores the need for further research into anesthetic-related ocular complications.

60.3K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

547
The different configurations of source-load connections include wye (star) and delta connections. The relationship between line and phase voltages and currents varies depending on the configuration. When the source is supplying power, it is transmitted through the wires to the load, and during this transmission, some power is absorbed by the wires, leading to line loss.

1.5K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

01:18Reducing Line Loss
393
In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

01:28Major Losses in Pipes
2.0K
When a fluid flows through a pipe, it experiences energy losses due to frictional resistance along the pipe walls, known as major losses. These energy losses result in a pressure drop, which varies based on the flow conditions — whether laminar or turbulent — and the specific physical properties of the fluid and pipe.
Fluid flow can be classified as laminar or turbulent, primarily based on the Reynolds number. This dimensionless number reflects the relative influence of inertial to viscous...

01:25Minor Losses in Pipes
2.0K
In pipe systems, minor losses refer to energy losses arising from components such as valves, bends, fittings, expansions, and other features that disrupt the steady flow of fluid. These disturbances cause energy dissipation through turbulence and resistance, which engineers quantify to manage system efficiency effectively.
Valves play a significant role in generating minor losses by obstructing or redirecting the fluid flow. When a valve is closed or partially closed, it restricts the flow...
