Intraretinal hemorrhages in cystoid macular edema
Archives of Ophthalmology (Chicago, Ill. : 1960)
|August 1, 1984
Summary
Retinal hemorrhages are common in cystoid macular edema. About 24.7% of cystoid macular edema cases show unique intraretinal hemorrhages not linked to other systemic diseases.
Area of Science:
- Ophthalmology
- Retinal Diseases
Background:
- Cystoid macular edema (CME) is a common cause of vision loss.
- Retinal hemorrhages can occur in various ocular conditions.
Purpose of the Study:
- To determine the incidence and characteristics of intraretinal hemorrhages specifically associated with CME.
- To differentiate CME-related hemorrhages from those caused by other systemic diseases.
Main Methods:
- Analysis of fundus photographs and fluorescein angiograms from 313 eyes with documented CME.
- Exclusion of 86 eyes with known causes of retinal hemorrhages (e.g., diabetes, vein occlusion).
- Evaluation of the remaining 227 eyes for associated intraretinal hemorrhages.
Main Results:
- 56 out of 227 eyes (24.7%) with CME showed intraretinal hemorrhages unrelated to systemic disease.
- Hemorrhages were typically oval, round, or linear.
- Hemorrhages often filled or partially filled the cystoid spaces, with observed blood-fluid levels in many cases.
Conclusions:
- Intraretinal hemorrhages can be a distinct feature of cystoid macular edema.
- These hemorrhages appear unique to CME when systemic causes are excluded.
- The morphology of these hemorrhages may provide diagnostic clues for CME.
