Total synechia is a medical condition where the iris of the eye is adhered to the lens, leading to vision impairment. The word "synechia" is spelled with the IPA phonetic transcription of /sınikiə/. The "s" is pronounced as /s/, the "y" as /j/, the "n" as /n/, and the "e" as /ɪ/. The second syllable is pronounced with a long "i" sound, represented by /aɪ/. The final syllable is pronounced with a schwa, represented by /ə/. Together, the word is pronounced as /toʊtəl sınikiə/.
Total synechia is a medical term used to describe a pathological condition characterized by complete adhesion or fusion of various structures within the body. Specifically, it refers to the complete fusion of different layers or structures within the eye, resulting in the complete loss of normal tissue separation.
Total synechia most commonly occurs within the eye, particularly in the posterior regions. It typically involves the adhesion or fusion of the iris, lens, and cornea. The condition can be congenital or acquired, often resulting from various eye diseases or trauma.
As a result of total synechia, the affected eye may experience significant vision impairment or even blindness. The fusion of the iris, lens, and cornea can cause obstruction of the visual pathway, preventing light from properly entering the eye.
Treatment options for total synechia are limited, and the approach taken depends on the underlying cause and severity of the condition. In some cases, surgical intervention may be necessary to attempt to separate the fused structures and restore some function and vision.
In summary, total synechia is a medical condition characterized by complete adhesion or fusion of different eye structures, leading to the loss of tissue separation and visual impairment. It can be congenital or acquired and may require surgical intervention for treatment.
Adhesion of the entire surface of the iris to the lens capsule.

The term "total synechia" is a medical term used to describe a condition characterized by the adhesion or fusion of different parts or structures. Specifically, it refers to the complete or entire fusion of the iris (the colored part of the eye) with either the cornea (the transparent front part of the eye) or the lens (the clear, flexible structure behind the iris).
The etymology of the term can be broken down as follows:
1. Total: The word "total" comes from the Latin word "totalis", which means whole, entire, or complete.
2. Synechia: The word "synechia" is derived from the Greek word "súnēchē", which means adherence or adhesion. In medical terminology, "synechia" refers to an abnormal adhesion between two tissues or organs that are not supposed to be fused together.
