Blue field entoptic test in patients with ocular trauma

Summary
The blue field entoptic test accurately predicts visual recovery after severe eye trauma. Normal test results correlate with significantly better vision, aiding prognosis in trauma patients.
Area of Science:
- Ophthalmology
- Retinal Physiology
Background:
- Severe ocular trauma often impairs visual acuity, making initial fundus examination difficult.
- Assessing macular function is crucial for predicting visual outcomes in these patients.
Purpose of the Study:
- To evaluate the utility of the blue field entoptic test in prognosticating macular function in patients with severe ocular trauma and poor initial visual acuity.
Main Methods:
- The blue field entoptic test was administered to 32 patients with severe ocular trauma and visual acuity of 6/60 or less.
- Patients' ability to perceive leukocytes in perifoveal capillaries was assessed.
- Visual acuity was monitored during follow-up.
Main Results:
- Ninety-five percent (20/21) of patients with normal blue field entoptic test responses achieved visual acuity of 6/12 or better.
- Ninety-one percent (10/11) of patients with abnormal test responses had visual acuity of counting fingers or less at follow-up.
Conclusions:
- The blue field entoptic test is a valuable, non-invasive tool for predicting macular function in patients with media opacities secondary to ocular trauma.
- This test aids in determining prognosis for visual recovery in challenging clinical scenarios.
