Optic neuropathy associated with clomiphene citrate therapy.
Department of Ophthalmology, Louisiana State University School of Medicine, New Orleans.
A 31-year-old woman developed acute visual loss in her right eye immediately after a 5-day course of CC for primary infertility. Although she gradually recovered vision, she did not return to 20/20 acuity in that eye. As CC may cause vascular sludging, it is hypothesized that increased blood viscosity resulted in sufficiently reduced flow in a posterior ciliary artery to produce an anterior ischemic optic neuropathy. Patients experiencing visual symptoms while taking clomiphene should have their eyes examined promptly for evidence of visual changes or optic nerve injury.

Visual disturbance secondary to clomiphene citrate.
Midwest Eye Institute, Methodist Hospital of Indiana, Indianapolis, USA.
OBJECTIVE: To identify a distinctive constellation of persistent visual abnormalities secondary to treatment with clomiphene citrate. DESIGN: Description of the clinical findings in three patients with visual disturbance secondary to clomiphene treatment. SETTING: A neuro-ophthalmology referral center. PATIENTS: Three women aged 32 to 36 years treated for infertility with clomiphene for 4 to 15 months. RESULTS: All three patients experienced prolonged afterimages (palinopsia), shimmering of the peripheral field, and photophobia while undergoing treatment with clomiphene. The results of the neuro-ophthalmologic examination and electrophysiologic studies were normal in all three patients. Unlike previously reported cases, visual symptoms did not resolve on cessation of treatment. Patients remain symptomatic from 2 to 7 years after discontinuing treatment with the medication. CONCLUSIONS: Treatment with clomiphene can cause prolonged visual disturbance. Patients who develop such symptoms should be advised that continued administration may cause irreversible changes. Women with characteristic visual symptoms should be questioned about past use of clomiphene.
