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...
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...
Angle Closure Glaucoma: Treatment01:28

Angle 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...

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...

Area of Science:

  • Ophthalmology
  • Medical Imaging
  • Clinical Diagnostics

Background:

  • Significant advancements in structural and functional testing for retinal diseases have occurred.
  • The clinical value and future trends of these testing modalities require clear identification.

Purpose of the Study:

  • To determine expert consensus on the value and performance of structural and functional testing methods for retinal disease.
  • To identify future needs in routine care and clinical trials for retinal disease management.

Main Methods:

  • A modified two-round Delphi study involving 33 international experts.
  • Utilized a Likert scale for agreement and Interquartile Range (IQR) for consensus on testing methods.

Main Results:

  • Strong agreement that structural testing currently dominates retinal disease detection and monitoring.
  • Moderate agreement on the continued importance of functional testing for complementary information.
  • Consensus that future care requires a combination of structural and functional testing, tailored to disease specifics.

Conclusions:

  • Expert insights highlight current and future needs in retinal disease management.
  • Findings are valuable for researchers designing future patient care tests and clinical trials.
