Skin Cancer01:30

Skin Cancer

5.6K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

890
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Glaucoma: Overview01:25

Glaucoma: Overview

1.1K
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.0K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.6K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Summary
This summary is machine-generated.

Uveal melanoma (UM), a rare eye cancer, often originates from GNAQ/GNA11 mutations. While treatments focus on preserving vision, metastatic disease remains a significant challenge, necessitating new therapeutic strategies.

Area of Science:

  • Ophthalmology
  • Oncology
  • Genetics

Background:

  • Uveal melanoma (UM) is the most common primary intraocular malignancy in adults.
  • UM typically arises from GNAQ or GNA11 mutations, distinguishing it from cutaneous melanomas.
  • Incidence is approximately 6 per million annually in Europe and the USA.

Purpose of the Study:

  • To review current understanding and treatment strategies for uveal melanoma.
  • To highlight challenges in managing metastatic uveal melanoma.
  • To suggest avenues for future therapeutic development.

Main Methods:

  • Literature review of uveal melanoma epidemiology, genetics, and treatment.
  • Analysis of ocular and metastatic disease management approaches.
  • Discussion of emerging therapeutic targets in tumor immunology and metabolism.

Main Results:

  • Ocular treatments aim to preserve vision and prevent metastasis, with radiotherapy and local resection being common.
  • Small tumors near the optic disc or fovea yield better ocular outcomes.
  • Metastatic disease affects nearly 50% of patients, primarily involving the liver and often proving fatal within a year.

Conclusions:

  • While ocular treatments have advanced, metastatic uveal melanoma remains difficult to treat.
  • Emerging therapies like partial hepatectomy, hepatic perfusion, and tebentafusp show promise for metastatic disease.
  • Further research into uveal melanoma immunology and metabolism is crucial for developing novel treatments.
