|January 15, 2019
Summary
Severe handheld laser pointer damage to the macula in a child resulted in poor vision but showed gradual visual and anatomical recovery over 4 years. Optical coherence tomography (OCT) revealed significant outer retinal disruption that slowly resolved, indicating potential for photoreceptor recovery.
Area of Science:
- Ophthalmology
- Retinal Imaging
- Vision Science
Background:
- Handheld laser pointers can cause severe retinal damage, particularly to the macula.
- Bilateral macular damage from laser pointers can lead to significant vision loss.
Observation:
- A 9-year-old boy experienced severe bilateral vision loss after prolonged exposure to a reflected red laser pointer.
- Clinical examination showed yellow streaks in the macula, and spectral domain optical coherence tomography (OCT) revealed outer retinal disruption.
Findings:
- Initial visual acuity was count fingers, with OCT showing extensive outer retinal disruption.
- Over 4 years, visual acuity improved to 20/30 bilaterally, and OCT demonstrated progressive reduction in the size of the outer retinal defect.
Implications:
- This case highlights the potential for gradual visual and anatomical recovery even after severe laser pointer-induced macular damage.
- Intact Bruch membrane may facilitate photoreceptor recovery, influencing the extent of visual improvement.

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

01:24Muscle Recovery and Fatigue
4.2K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

Regional terms describe anatomy by dividing the body parts into different regions that contain structures involved in contributing similar functions. Using these terms helps increase the accurate description and identification of the particular region of interest or region affected by the disease.
Primarily, the human body has two major regions, the axial and appendicular regions. The axial region comprises regions from the head to the abdomen and makes up the central body axis. In contrast,...

Long-term memory is a relatively permanent type of memory, capable of storing vast amounts of information over extended periods. Its storage capacity is generally considered unlimited.
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...
