Skin Cancer

5.7K
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

963
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...

Angle Closure Glaucoma: Treatment

1.2K
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...

Glaucoma: Overview01:25

Glaucoma: Overview

1.2K
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...

Area of Science:

  • Ophthalmology
  • Oncology
  • Pathology

Background:

  • Choroidal melanoma is a rare intraocular malignancy.
  • Ocular tumors can present with varied clinical features.
  • Pigment epithelial adenomas share some clinical similarities with melanomas.

Purpose of the Study:

  • To report a unique case of untreated choroidal melanoma.
  • To emphasize the diagnostic challenges posed by exudative choroidal melanoma.
  • To differentiate this presentation from pigment epithelial adenomas.

Main Methods:

  • Clinical case presentation.
  • Ophthalmic examination findings.
  • Review of relevant literature.

Main Results:

  • An untreated choroidal melanoma exhibited significant exudation.
  • The clinical presentation mimicked that of pigment epithelial adenomas.
  • Histopathological confirmation was essential for definitive diagnosis.

Conclusions:

  • Untreated choroidal melanoma can present with exudative features, posing a diagnostic challenge.
  • Clinical differentiation from benign conditions like pigment epithelial adenomas requires careful evaluation.
  • Prompt diagnosis and management are vital for favorable outcomes in choroidal melanoma.
