Multicenter Study
Impact of the revised american academy of ophthalmology guidelines regarding hydroxychloroquine screening on actual practice.
To determine the impact of the revised academy guidelines on screening for hydroxychloroquine retinopathy. ⋯ Detection of toxic daily dosing is a cost-effective way to reduce hydroxychloroquine toxicity, but height, weight, and daily dose were commonly not checked. The revised guidelines, emphasizing mfERG, SD-OCT, or FAF, raised screening cost without improving case detection. The recommended 5-year screening-free interval for low-risk patients after baseline examination was ignored.

To determine whether patients with a sickle-cell hemoglobinopathy without glaucoma have peripapillary retinal nerve fiber layer (RNFL) thinning by spectral-domain optical coherence tomography. ⋯ Nonglaucomatous, black sickle-cell patients with focal macular thinning on spectral-domain optical coherence tomography have significantly thinner peripapillary RNFL than those without macular thinning or controls. The degree of thinning correlates with severity of temporal macular thinning. These patients may require different peripapillary RNFL thickness thresholds for future glaucoma evaluations.
