Pulseless and blindness - An ophthalmologist's role in diagnosing Takayasu arteritis: Case series and brief review of literature.

PURPOSE: To study the initial presenting symptoms of Takayasu arteritis in unsuspecting patients.

METHODS

The underlying systemic condition was suspected in five subjects at a tertiary eye care center based on their ocular features. Similar reports in the literature were collated and analyzed for the common presenting features of undiagnosed Takayasu arteritis.

RESULTS

The most common presenting ophthalmic symptoms were vision loss (86.8%), ocular pain (21.1%), eye redness (18.4%), and photophobia (5.3%). There were no reports of glaucoma at presentation. Pupillary abnormalities (42.1%), microaneurysms in retinal mid-periphery (42.1%) and venous engorgement (28.9%) were the most common presenting signs. Despite systemic symptoms such as headache, dizziness, fatigue, weakness, arm claudication, fever, anorexia, weight loss, and syncope in 76.3% of cases, the patients in this series had never sought medical care before developing ocular symptoms.

CONCLUSION

Takayasu arteritis may remain latent until the ophthalmic complications compel the patient to seek medical attention. Hence, ophthalmologists need to be aware of the seemingly innocuous presentations of the disease.
