amiodarone | optic neuropathy | sudden visual loss |
chlorothiazide | oculomotor nerve palsy | |
indapamide | cataract | bilateral |
chlorpropamide | optic neuropathy | visual loss |
glibenclamide | (1) myopia, (2) hyperopia, (3) lens changes | vision returned to normal on stopping therapy |
interferon | retinopathy | mostly asymptomatic |
streptokinase | retinal/vitreous haemorrhage | marked reduction in vision |
warfarin | vitreous haemorrhage | blindness |
erythropoietin | visual hallucinations | mechanism uncertain |
isoniazid | optic neuropathy | vision normalised after stopping |
ethambutol | optic neuropathy | |
phenformin + ethanol | blindness | secondary to lactic acidosis following drinking binge |
oral contraceptive | (1) diabetic retinopathy, (2) colour vision disturbance | (1) no adverse effect (2) mechanism uncertain |
phenothiazines | cataracts | large study−strong association |
allopurinol | cataracts | risk independent of diabetes in one study but significant factor in another |
cidofovir | iritis + hypotony | iritis more likely in diabetes |
scopolamine | acute angle glaucoma | predictable from transdermal patch |
steroids (oral) | open angle glaucoma and ocular hypertension | large study confirmed increased risk |
steroids (oral) | cataracts | increased risk |
steroids (eye drops) | cataracts | small study but significant risk |
steroids (inhaled) | cataracts | increased risk |
OKT3
| reduced visual acuity | uncertain mechanism |
