Summary
Conjunctival melanoma is a rare cancer affecting middle-aged white individuals. Early diagnosis and awareness are crucial for improving survival rates in black patients, where it is extremely rare but can arise from primary acquired melanosis.
Area of Science:
- Ophthalmology
- Dermatology
- Oncology
Background:
- Conjunctival melanoma is a rare malignancy, predominantly affecting middle-aged white populations with an incidence of 0.012 per 100,000.
- While extremely rare in Black individuals, conjunctival melanoma cases have been documented.
Observation:
- Skin melanoma in Black individuals often presents on non-sun-exposed areas like mucous membranes, palms, and soles.
- Primary acquired melanosis (PAM) can precede melanoma development, even in Black patients.
- Differentiating PAM from racial melanosis in Black populations presents clinical and histopathological challenges.
Findings:
- Conjunctival melanoma, though rare in Black individuals, can develop from primary acquired melanosis.
- Accurate clinical and histopathological differentiation of primary acquired melanosis from racial melanosis is critical in Black patients.
Implications:
- Increased awareness and education regarding conjunctival melanoma are vital for early diagnosis in Black patients.
- Prompt diagnosis and management are essential for improving survival outcomes for Black individuals with conjunctival melanoma.

01:20The Retinoblastoma Gene
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,...

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.

01:25Glaucoma: 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...
01:27Open 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...
