synechia

Thân thiện

A doctor uses a slit lamp to examine a patient's eye for synechia.

Definition

Noun: - Adhesions between the iris and the lens or cornea: A medical condition where the iris abnormally adheres to either the lens of the eye or the cornea. This adhesion typically results from trauma, eye surgery, or occurs as a complication of other eye diseases such as glaucoma or cataract. If untreated, it can lead to impaired vision or blindness.

Usage Examples

• Noun:
  • The ophthalmologist diagnosed the patient with synechia following the complicated cataract surgery.
  • Synechia is a serious complication that can develop from untreated uveitis.
  • The adhesion caused by the synechia was preventing the normal flow of aqueous humor in the eye.

Advanced Usage

• "Anterior synechia": Refers specifically to an adhesion between the iris and the cornea.
  • Anterior synechia can angle-closure glaucoma by blocking the drainage angle of the eye.
• "Posterior synechia": Refers specifically to an adhesion between the iris and the lens.
  • The inflammation led to the formation of a posterior synechia, which pinned the pupil in place.

Variants and Related Words

• Synechiae (n): The plural form of synechia.
  • The examination revealed multiple synechiae in the patient's left eye.
• Synechial (adj): Pertaining to or of the nature of a synechia.
  • The synechial band was carefully dissected during the procedure.

Synonyms

• Adhesion: The process or condition of sticking or growing together, often used in a broader medical context.
• Iris adhesion: A more descriptive term for the condition.

Notes on Meaning

This term is highly specific to the field of ophthalmology (eye medicine). It describes a pathological anatomical condition, not a symptom or a disease process itself. The primary concern with synechia is its potential to disrupt the eye's internal structures and fluid dynamics, leading to secondary issues like glaucoma and vision loss.
