specular microscopy
Diagnostic technique for evaluating corneal endothelial cell count and morphology.
Full Definition
Specular microscopy is a non-invasive diagnostic imaging technique used to assess the corneal endothelium, the innermost layer of the cornea. This examination provides detailed information about endothelial cell count, size, shape, and overall health. The test is crucial for preoperative evaluation before cataract surgery, corneal transplantation, and other intraocular procedures. Results help surgeons assess surgical risk and plan appropriate interventions. Normal endothelial cell counts typically range from 2000-3000 cells per square millimeter in healthy adults.
Usage
Usage note: Essential preoperative test for intraocular surgery planning.
In Context
- "Preoperative specular microscopy revealed an endothelial cell count of 2200 cells/mm²." — Surgical consultation note
- "Specular microscopy was repeated six months postoperatively to assess endothelial cell loss." — Follow-up examination
