Summary of individual studies and outcome measures.
| Study | Sample Size, Study Duration | Treatment, Primary Eye | Treatment, Contralateral Eye | Analysis |
|---|---|---|---|---|
| Confocal Microscopy/MB Distribution | n=13 total BN rats, euthanized at: 10 mins post injection (n=5), 20 mins post injection (n=3), 30 mins post injection (n=5) | 30 mM MB (5O ul, retrobulbar) | HBSS (50 ul, retrobulbar) | Confocal microscopy: MB transport to sclera |
| Scleral Stiffening in Rats Euthanized at Day 0 (Immediately After Treatment) | n=7 BN rats, euthanized immediately post treatment | 3 mM MB (100 ul retrobulbar), illumination* | HBSS (100 ul, retrobulbar) | Whole globe inflation: scleral strain |
| Scleral Stiffening in Rats Euthanized 6 Weeks After Treatment | n=8 BN rats, euthanized 6 weeks post treatment | 3 mM MB (100 ul retrobulbar), illumination* | HBSS (100 ul, retrobulbar) |
Whole globe inflation: scleral strain Electroretinography: retinal function Axon Count/Grade: ON/retinal health |
| Histology (MB+light) | n=3 BN rats, euthanized 10 days post treatment | 3 mM MB (100 ul retrobulbar), illumination* | N/A** | Histology: ON/retinal morphology |
| Histology (Light Only) | n=3 BN rats, euthanized 10 days post treatment | Illumination* | N/A** |
Histology: ON/retinal morphology OCT: retinal morphology |
Abbreviations: MB (methylene blue), BN (Brown Norway), HBSS (Hank's Balanced Salt Solution), ON (Optic Nerve), OCT (Optical Coherence Tomography),
Illumination was performed using a 30 minute transpupillary exposure of the peripapillary sclera to 424 m W/cm2 660 nm light.
Naive (untreated) controls.
