Introduction Anastrazole (Arimidex®) Aromatase inhibitor (AI), suppress estrogen
synthesis from androgens Used as an adjuvant therapy in breast/ovarian
cancer treatment Ocular side effects of AI’s: retinal
hemorrhages, visual disturbances, hemiretinal artery occlusion
Androgen deficiency has been linked to meibomian gland dysfunction

Purpose Few studies reported the higher
prevalence of moderate to severe dry eye syndrome in older women
None of the studies noted the prevalence of ocular surface symptoms and signs among AI users
We observed that several patients who presented with dry eye symptoms were using anastrazole
Investigation of an association between anastrazole and dry eye syndrome
Methods Retrospective chart review Computerized search of Wills Cornea
Service electronic health records between from August 2008 to April 2010 for patients on Anastrazole
Results were compared with the age-matched controls from a published study by Schaumberg et al.1
1 Schaumberg DA, Sullivan DA, Buring JE, Dana MR. Prevalence of dry eye syndrome among US women. Am J Ophthalmol 2003; 136:318-26.
Results Total patients on anastrazole: 16
Caucasian women Breast cancer: 15 (94%) Ovarian cancer: 1 (6%) Treatment of Primary Cancer:
Surgery: 9 (56%) Chemotherapy: 4 (25%) Radiotherapy: 2 (13%)
Mean ± SD age: 67 ± 13 years (range 50-95)
Medical conditions Diabetes mellitus: 5 (31%) Hypertension: 5 (31%) Hyperthyroidism: 2 (13%) Hypercholesterolemia: 1 (6%) Cardiac arrhythmia: 1 (6%)
Ocular disorders at presentation and
treatment* Dry eyes: 6 (38%) Glaucoma: 5 (31%) Blepharitis: 4
(25%) Fuch’s dystrophy:
4 (25%) Keratoconus: 2
(13%) PBK, ptosis (6%),
fungal ulcer, chronic conjunctivitis: 1 (6%) each
Tear supplement: 5 (31%)
Anti-glaucoma: 5 (31%)
Topical sodium Chloride: 3 (19%)
No treatment: 3 (19%)
Topical antibiotics: 2 (13%)
Cyclosporine: 2 (13%)
Anti allergic: 1 (6%)
* Few patients had more than one condition at presentation and a combination of topical medications
Presenting Ocular Symptoms*
Among the control population (65-69 years), dryness and irritation were found in 5.7% and 0.6% respectively. More than one symptom was found in 9.5% * Few patients had more than one

Treatment Tear supplement: 15 patients Lubricating ointment/gel: 3 patients Antibiotic ointment: 3 patients Punctal plugs: 2 patients Cyclosporine (topical 0.05%): 2 patients
Summary at the Last follow-up No. of patients at the follow up: 11 (69%) No of patients lost to follow up: 5 (31%) No of patients on Anastrazole: 10 (91%) Mean ± SD follow-up: 14 ± 7.7 months
(range 2-25) After treatment of dry eyes:
Improvement dry eye symptoms: 7 (64%) Persistent dry eye symptoms: 3 (27%) Mild discomfort: 1 (9%)
Tumor status: Remission of breast cancer: 9 (81%) Remission of ovarian cancer: 1 (9%) Systemic metastasis: 1 (9%)
Conclusions The prevalence of ocular surface disease
appears to be higher in the patients taking anastrazole than in age-matched control population1
Anastrazole is likely a contributing factor to dry eye symptoms
A larger scale investigation is necessary to evaluate this correlation further
