    Visual fields in chloroquine


    Plaquenil is less toxic than chloroquine; however, long-term use of either drug can result in macular toxicity, leading to devastating irreversible vision loss. The mechanism of this toxicity is not clearly understood, though it is believed that the drug molecule binds to melanin in the retinal pigment epithelium (RPE).

    To analyze Humphrey visual field HVF findings in hydroxychloroquine HCQ retinal tests were interpreted retrospectively in this observational case series of 15 patients with HCQ toxicity. Patients seen at Lahey Clinic were identified by. To quantify the variability of scotomas detected by 10–2 visual field VF testing with a red target in patients taking hydroxychloroquine without and with retinopathy. Retrospective review of clinical charts and VFs. Twenty-four patients taking. Visual field abnormalities occurred in 35 patients. Five patients developed hydroxychloroquine ocular adverse effects, of which 4 were visual field defects and 1 was significant vortex keratopathy. None of these patients developed visual symptoms, changes in visual acuity, or fundus abnormalities resulting from drug toxic effects nor did they.

    Binding of the drug to melanin in the RPE contributes to, or prolongs, its toxic effects. This leads to disruption and damage to the photoreceptors and outer nuclear and plexiform layer, sparing the foveal center and resulting in the “bull’s eye” appearance in the late stage of the disease.

    A visual field test is a method of measuring an individual's entire scope of vision, that is their central and peripheral side vision. Visual field testing maps the visual fields of each eye individually and can detect blind spots scotomas as well as more subtle areas of dim vision. A baseline ocular examination is recommended within the first year of starting Plaquenil. The baseline exam should include best corrected distance visual acuity BCVA, an automated threshold visual field VF of the central 10 degrees with retesting if an abnormality is noted, and spectral domain ocular coherence tomography SD-OCT. Oct 01, 2018 Use of Chloroquine phosphate tablets for indications other than acute malaria is contraindicated in the presence of retinal or visual field changes of any etiology. Use of Chloroquine phosphate tablets is contraindicated in patients with known hypersensitivity to 4-aminoquinoline compounds. Warnings. Chloroquine-Resistant Malaria

I have been SOOOO tempted to reach for that evening dose today. Let me tell you what weaning down from Plaquenil is like. Hydroxychloroquine - Side Effects, Dosage, Interactions.
