Ophthalmic manifestations in Asian patients with systemic lupus erythematosus.

AIM OF STUDY

To determine the spectrum and prevalence of ophthalmic manifestations of systemic lupus erythematosus (SLE) in Asian patients.

METHODS

We performed a standardised ophthalmic examination on consecutive Asian patients with SLE referred from a tertiary rheumatology unit to an ophthalmology department.

RESULTS

Seventy patients were included in the study. There were 66 females (94%) and 4 males (6%). The mean (range) age of the patients was 32.9 (9-67) years. Five patients (7%) had ophthalmic symptoms while 65 (93%) were asymptomatic. Eighty-three eyes of 45 patients had abnormal Schirmer's #1 test and 27 of these eyes of 17 patients also had concomitant rose bengal staining of the cornea and/or conjunctiva. Seventeen eyes of 9 patients had retinal vascular lesions. Fourteen of these eyes had mild microangiopathic retinopathy with best-corrected visual acuity (BCVA) 6/12 or better and 3 had retinal vaso-occlusive disease with BCVA worse than 6/12. Twenty-eight eyes of 14 patients had cataract and 3 eyes of 2 patients had raised intraocular pressure. Twelve eyes of 7 patients had BCVA worse than 6/12 because of optic neuropathy (4 eyes), posterior subscapsular cataract (4 eyes), retinal vaso-occlusive disease (3 eyes) and phthisis bulbi (1 eye). None had any eyelid lesion, extraocular motility disorder or retrochiasmal disorder of vision.

CONCLUSIONS

Asymptomatic dry eye is the most common ocular finding in patients with SLE. Sight-threatening complications of SLE include retinal vaso-occlusive disease and optic neuropathy.
