Limited choroidal hemorrhage associated with intracapsular cataract extraction
Archives of Ophthalmology (Chicago, Ill. : 1960)
|December 1, 1984
Summary
Limited choroidal hemorrhage (LCH) occurred in 3.07% of cataract surgeries, significantly higher in highly myopic eyes. LCH may share mechanisms with expulsive choroidal hemorrhage and is associated with cardiovascular disease.
Area of Science:
- Ophthalmology
- Cardiovascular Medicine
Background:
- Limited choroidal hemorrhage (LCH) is a potential complication during cataract surgery.
- The incidence and risk factors for LCH, particularly in myopic patients, require further investigation.
Purpose of the Study:
- To determine the incidence of LCH during cataract extraction.
- To investigate the association between LCH and patient factors, including myopia and cardiovascular disease.
Main Methods:
- Prospective study of 521 eyes undergoing cataract extraction.
- Data collected on LCH occurrence, refractive error (myopia), vitreous loss, and systemic conditions.
- Statistical analysis to identify correlations.
Main Results:
- LCH was observed in 3.07% of eyes.
- Incidence was significantly higher in highly myopic eyes (14.49%) compared to moderately myopic (4.49%) and non-myopic eyes (0.77%).
- A positive correlation between LCH and vitreous loss in myopic eyes was noted. An association with cardiovascular disease was found in 14 of 16 LCH cases.
Conclusions:
- LCH is a complication of cataract surgery, with increased risk in myopic patients.
- LCH and expulsive choroidal hemorrhage may share underlying pathophysiologic mechanisms.
- Cardiovascular disease is a potential associated systemic factor.
