Abstract

Insights

Intraocular tumors can cause secondary glaucoma through various mechanisms. Treating the primary tumor is key, with medical, laser, or surgical interventions for glaucoma, avoiding certain surgeries in active malignancy.

Area of Science:

  • Ophthalmology
  • Oncology

Background:

  • Secondary glaucoma is a significant complication of intraocular tumors.
  • Early consideration is crucial for patients with known tumors or unexplained unilateral/refractory glaucoma.

Purpose of the Study:

  • To review the mechanisms by which intraocular tumors cause secondary glaucoma.
  • To discuss current management strategies for these cases.

Main Methods:

  • Literature review of intraocular tumors associated with secondary glaucoma.
  • Analysis of tumor-related glaucoma mechanisms and treatment outcomes.

Main Results:

  • Common culprits include iris melanoma, choroidal melanoma, retinoblastoma, and others.
  • Glaucoma mechanisms involve tumor invasion, angle closure, and neovascularization.
  • Tumor treatment can resolve glaucoma; management includes medical, laser, and specific surgical approaches.

Conclusions:

  • Intraocular tumors frequently lead to secondary glaucoma.
  • Treatment of the primary malignancy is paramount for glaucoma resolution.
  • Careful selection of glaucoma treatment is necessary, avoiding certain procedures in active tumors.

Glaucoma: Overview01:25

Glaucoma: 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...

Secondary Active Transport01:55

Secondary Active Transport

One example of how cells use the energy contained in electrochemical gradients is demonstrated by glucose transport into cells. The ion vital to this process is sodium (Na+), which is typically present in higher concentrations extracellularly than in the cytosol. Such a concentration difference is due, in part, to the action of an enzyme “pump” embedded in the cellular membrane that actively expels Na+ from a cell. Importantly, as this pump contributes to the high concentration of...

Secondary Healthcare System

Secondary healthcare is offered by a specialist, generally in hospitals or clinics for patients referred by primary healthcare providers. It occurs when a person has an illness or injury that requires specific medical care. Secondary care is often referred to as acute care. Secondary care can range from uncomplicated care to repair a minor laceration or treat a strep throat infection to more complicated emergent care, such as treating a head injury sustained in an automobile accident.

Open Angle Glaucoma: Treatment01:27

Open 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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Primary and Secondary Growth in Roots and Shoots

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.
