Spectral domain optical coherence tomography study of pearl-like lesions in the anterior chamber.
Abstract
AIM
To study the morphological pattern of pearl-like lesions in the anterior chambers of children before and after management
using anterior segment spectral domain optical coherence tomography (SD-OCT).
PATIENTS AND METHODS
This was a prospective, observational cross-sectional study of patients presenting with peculiar pearl-like lesions in the
anterior chamber of their eyes. 1 mL of betamethasone sodium phosphate (2 mg/mL) and betamethasone dipropionate (5 mg/mL)
was injected subconjunctivally. Follow-ups of all patients were conducted for a period of 6 weeks. Anterior segment imaging
was done using SD-OCT and also photo slit lamp before and after management.
RESULTS
Twelve eyes of 12 patients were included in this study. These patients presented with pearl-like lesions in the anterior chamber
with signs of anterior uveitis. There was no history of ocular injury or tuberculosis in any patients. Six weeks after subconjunctival
steroid injection, all patients achieved mean best-corrected visual acuity, which changed from 0.2 (range 0.1-0.4) to 0.5
(range 0.4-0.8), and the severity of iritis decreased. SD-OCT showed that the lesions at presentation appeared as a globular
noncystic mass attached to the back of the cornea, encroaching on the angle of the eye, and attached to the anterior surface
of the iris at some points.
CONCLUSION
SD-OCT for imaging the anterior segment allowed us to exclude the cystic nature of this pearly lesion. Some similarities may
exist between these pearly lesions and superficial phlyctenular keratitis, which may support the immunological and inflammatory
origin of these lesions.
