Summary
Pigmented paravenous chorioretinal atrophy (PPCRA) presents as patches of atrophy and pigment clumping along retinal veins. This usually nonprogressive condition typically shows normal retinal vessels, macula, and optic discs.
Area of Science:
- Ophthalmology
- Retinal Diseases
- Medical Imaging
Background:
- Pigmented paravenous chorioretinal atrophy (PPCRA) is a rare condition affecting the choroid and retina.
- Characterized by pigmentary changes and tissue atrophy along retinal venous pathways.
Purpose of the Study:
- To describe the key clinical and imaging features of PPCRA.
- To highlight its typical nonprogressive nature and normal surrounding ocular structures.
Main Methods:
- Clinical examination of patients diagnosed with PPCRA.
- Ophthalmoscopic and imaging (e.g., OCT, fundus photography) review.
Main Results:
- PPCRA exhibits distinct patches of chorioretinal atrophy and pigmentary abnormalities.
- These changes are characteristically distributed along the course of retinal veins.
- In most cases, retinal vasculature, macula, and optic discs appear unaffected.
Conclusions:
- PPCRA is identifiable by its unique pattern of atrophy and pigment clumping along veins.
- The condition is generally stable and does not typically involve the macula or optic nerve.

4.3K
The color of the skin is influenced by a number of pigments, including melanin, carotene, and hemoglobin. Recall that melanin is produced by cells called melanocytes, which are found scattered throughout the stratum basale of the epidermis. The melanin is transferred to the keratinocytes via melanosomes.
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...

The energy required to carry out photosynthesis is light— typically electromagnetic radiation from the sun. The range of all possible wavelengths is known as the electromagnetic spectrum.
Photons
A photon is a discrete electromagnetic particle or bundle of energy. Photons are characterized by their frequency, wavelength, and amplitude, similar to the properties of a wave. Waves with higher frequencies transmit more energy and have shorter wavelengths than longer wavelengths that transmit...

01:33Pleiotropy
43.3K
Pleiotropy is the phenomenon in which a single gene impacts multiple, seemingly unrelated phenotypic traits. For example, defects in the SOX10 gene cause Waardenburg Syndrome Type 4, or WS4, which can cause defects in pigmentation, hearing impairments, and an absence of intestinal contractions necessary for elimination. This diversity of phenotypes results from the expression pattern of SOX10 in early embryonic and fetal development. SOX10 is found in neural crest cells that form melanocytes,...

Green algae and plants, including green stems and unripe fruit, harbor chloroplasts—the vital organelles where photosynthesis takes place. In plants, the highest density of chloroplasts is found in the mesophyll cells of leaves.

69.9K
Although structurally similar to photosystem II (PSII), photosystem I (PSI) is has a different electron supplier and electron acceptor.
Both these photosystems work in concert. An excited electron from PSII is relayed to PSI via an electron transport chain in the thylakoid membrane of the chloroplast, which is comprised of the carrier molecule plastoquinone, the dual-protein cytochrome complex, and plastocyanin. As electrons move between PSII and PSI, they lose energy and must be re-energized...

76.9K
Gas exchange, the intake of molecular oxygen (O2) from the environment and the outflow of carbon dioxide (CO2) into the environment, is necessary for cellular function. Gas exchange during respiration occurs largely via the movement of gas molecules along pressure gradients. Gas travels from areas of higher partial pressure to areas of lower partial pressure. In mammals, gas exchange occurs in the alveoli of the lungs, which are adjacent to capillaries and share a membrane with them.
