SD-OCT revealed glial membranes on the optic nerve head in RP patients. These membranes correlated with waxy pallor, suggesting they contribute to this clinical sign in RP.

SD-OCT-observed extensive epiretinal membrane adherence and fibrillary changes strongly predict increased surgical difficulty during ERM removal, aiding preoperative planning and surgical strategy.

This study found thinner retinal nerve fiber layers in HIV patients correlated with worse driving simulator performance, suggesting ophthalmologic monitoring is crucial for driving safety.

Scanning laser polarimetry showed HIV-positive patients with a history of very low CD4 counts have retinal nerve fiber layer thinning, suggesting potential glaucoma-like damage even without infectious retinitis.

This study found HIV patients without retinitis showed inner retinal damage on mfERG, but these defects didn't always align with perimetry. This suggests HIV can independently affect inner retinal function.

This study found that in HIV patients, immune recovery (increased CD4 counts) from HAART is associated with a rise in intraocular pressure, reversing HIV-induced IOP reduction.

This study found HIV patients with a history of low CD4 counts, even without CMV retinitis, have significant retinal nerve fiber thinning, suggesting OCT can detect subclinical HIV-related visual damage.
