Higher HCQ dose ups incident retinopathy risk
23 Jan 2023
A recent study reports an overall risk of 8.6 percent for hydroxychloroquine (HCQ) retinopathy after 15 years in a large cohort with active surveillance retinopathy screening. Notably, most of these cases are mild, and a higher HCQ dose appears to result in progressively greater risk for incident retinopathy.

The number of optical coherence tomography (OCT) scans must be increased relative to current clinical practice to get a more accurate diagnosis of retinal nerve fibre layer (RNFL) worsening, according to a recent study.
IOP-induced ONH strains negatively tied to retinal sensitivity in glaucoma patients
12 Jan 2023
Optic nerve head (ONH) strains under intraocular pressure (IOP) show a negative association with retinal sensitivity in patients with open-angle glaucoma, according to a study. In particular, high-tension glaucoma (HTG) patients with higher ONH strains are more likely to show lower retinal sensitivities.
