Microhyphema
Abstract:
A case of microscopic hemorrhage into the anterior chamber is described. Slit-lamp examination disclosed a steady fine stream of blood issuing from a tiny grayish bulblike microhemangioma at the pupillary border. Fluorescein biomicroscopy revealed several similar microhemangiomas on the borders of each pupil. It is presumed that minor ocular irritation, due either to poison ivy or to a menthol (0.70%) cream which the patient applied to her face, precipitated the microhyphema.
Insights
A case study details microscopic hemorrhage in the anterior chamber of the eye, originating from microhemangiomas. Ocular irritation from external factors likely triggered this condition, known as microhyphema.
Area of Science:
- Ophthalmology
- Vascular Biology
- Dermatology
Background:
- Microscopic hemorrhage into the anterior chamber (microhyphema) can have various etiologies.
- Identifying the source of bleeding is crucial for appropriate patient management.
Observation:
- A patient presented with a steady stream of blood from a microhemangioma at the pupillary border.
- Slit-lamp examination and fluorescein biomicroscopy identified multiple similar microhemangiomas on the pupillary borders.
Findings:
- The identified lesions were characterized as tiny, grayish, bulblike microhemangiomas.
- The microhyphema was presumed to be precipitated by minor ocular irritation.
Implications:
- This case highlights microhemangiomas as a potential, albeit rare, cause of microhyphema.
- External irritants, such as topical creams or plant contact, may trigger bleeding in susceptible individuals with ocular vascular anomalies.
