Summary
Topographic vitreous fluorophotometry revealed increased blood-ocular barrier permeability in optic neuropathies, even with normal fluorescein angiography. This technique differentiates fluorescein leakage between the optic disc and macula.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
- Medical Imaging
Background:
- Optic neuropathies can present with normal fluorescein fundus angiography.
- Assessing blood-ocular barrier integrity is crucial for diagnosing and understanding optic nerve diseases.
Purpose of the Study:
- To investigate optic neuropathies using axial and paraaxial fluorophotometry.
- To determine differences in fluorescein leakage between the macula and optic disc in optic neuropathies.
Main Methods:
- Studied eyes with inflammatory and ischemic optic neuropathies during acute and late phases.
- Utilized axial and paraaxial fluorophotometry (topographic vitreous fluorophotometry).
- Included a control group of healthy eyes and performed comprehensive ophthalmic examinations.
Main Results:
- Increased permeability of the blood-ocular barrier was observed in acute optic neuropathies.
- Fluorophotometry showed differences in fluorescein leakage between optic disc and macular regions.
- In the late phase with optic disc atrophy, fluorescein leakage values were lower than in controls.
Conclusions:
- Topographic vitreous fluorophotometry is valuable for detecting blood-ocular barrier abnormalities in optic neuropathies.
- This method can differentiate fluorescein leakage patterns in the macula and optic disc.
- Fluorophotometry offers insights into optic neuropathies when standard angiography is normal.
