Limited choroidal hemorrhage associated with extracapsular cataract extraction
Archives of Ophthalmology (Chicago, Ill. : 1960)
|March 1, 1987
Summary
Extracapsular cataract extraction shows a lower rate of choroidal hemorrhage than intracapsular extraction, particularly in high myopia patients. This complication did not impact final visual function.
Area of Science:
- Ophthalmology
- Surgical Complications
Background:
- Choroidal hemorrhage is a potential complication during cataract surgery.
- Previous studies indicated varying rates based on surgical techniques.
Purpose of the Study:
- To compare the incidence of limited choroidal hemorrhage between extracapsular cataract extraction (ECCE) and intracapsular extraction (ICCE).
- To identify risk factors associated with choroidal hemorrhage during ECCE.
Main Methods:
- Retrospective analysis of 368 eyes undergoing ECCE.
- Comparison of hemorrhage rates with a previous ICCE study.
- Statistical analysis to determine risk factors such as high myopia, general anesthesia, glaucoma, and combined procedures.
Main Results:
- A 2.2% rate of limited choroidal hemorrhage was observed with ECCE, lower than the 3.07% rate with ICCE.
- High myopia was a significant risk factor, especially with general anesthesia.
- Glaucoma and combined ECCE with trabeculectomy increased susceptibility.
Conclusions:
- ECCE is associated with a lower incidence of limited choroidal hemorrhage compared to ICCE.
- Myopia, general anesthesia, and specific co-existing ocular conditions are key risk factors.
- Limited choroidal hemorrhage does not adversely affect final visual outcomes post-cataract surgery.
