Risk factors for retinopathy
A 67-year-old man observed transient green-yellow spots with both eyes. There is no diet or medical therapy to prevent or treat this type of retinal toxicity; the best approach is primary prevention. Corticosteroid themselves probably have minimal toxic effects on the retina but the vehicles causes the retinal necrosis. This solution is subsequently drawn up into syringe and injected intravenously. Certain sulfa-based drugs can cause swelling of the ciliary body and lead to the development of angle-closure glaucoma.

Bull's eyemaculopathy with early conedegeneration sodium fluorescein into an antecubital vein. After repeated injections, collateral vasculature develops, allowing the particles to enter the systemic circulation and embolizes to other organs, including the eye. While facial flushing is the most common systemic side effect, patients may have visual complaints including blurred vision, decreased vision and metamorphopsia. Description Medications like plaquenil and chloroquine can induce degenerative changes in the ganglion cells and photoreceptor cells of the retina. Indian J Dermatol. Bullâs eye maculopathy is a rare dystrophy, also known as benign concentric annular macular dystrophy (BCAMD). The signs include vortex ; keratopathy and cataract. With cessation of drug cme resolves, vision returns to normal. A scotoma is usually a subtle & located within 10 degree of fixation. Used I treatment of CMV retinitis

Mechanism
Preservatives add to the toxicity. Perimetry – non specific, most characteristic – paracentral or ring scotoma, FFA – loss of RPE & choriocapillaris within the areas of depigmentation. Thioridazine
