Summary
Uveal melanoma, the most common adult eye tumor, has a poor prognosis due to liver metastasis. Despite diagnostic and treatment advances, mortality rates for this rare cancer remain unchanged since 1973.
Area of Science:
- Ophthalmology
- Oncology
- Pathology
Background:
- Uveal melanoma is the most common primary intraocular malignancy in adults.
- It typically originates in the choroid, presenting with characteristic growth patterns.
- Histopathological classification relies on dominant cell types: spindle, epithelioid, or mixed.
Purpose of the Study:
- To review the key aspects of uveal melanoma, including its classification, prognostic factors, and treatment challenges.
- To highlight the persistent high mortality rates despite advances in diagnosis and treatment.
Main Methods:
- Review of existing literature on uveal melanoma.
- Analysis of histopathological classifications and prognostic indicators.
- Examination of treatment outcomes and survival data.
Main Results:
- Key prognostic factors include cell type, nucleolar size, tumor dimension, and mitotic figures.
- Liver metastasis is a primary determinant of poor patient prognosis.
- Mortality rates for uveal melanoma have remained stagnant since 1973.
Conclusions:
- Uveal melanoma remains a significant clinical challenge due to its aggressive metastatic potential, particularly to the liver.
- Further research is needed to improve survival outcomes for patients with uveal melanoma.

01:25Glaucoma: Overview
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...
01:30Skin Cancer
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.

01:27Open Angle Glaucoma: Treatment
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.

01:28Angle Closure Glaucoma: Treatment
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...
01:22Microbiome of the Eye
The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...
01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
