Anterior segment optical coherence tomography is useful for determining the differences between the cross-sectional areas of the conjunctiva and the tear meniscus after conjunctival cauterization, a study found.
"[Anterior segment] OCT has numerous advantages over other methods such as slit-lamp biomicroscopy, ultrasound biomicroscopy and in vivo confocal microscopy for conjunctival imaging," the study authors said.
The prospective, nonrandomized, consecutive case study enrolled 12 eyes of seven patients between the ages of 56 years and 87 years who had conjunctivochalasis. All patients underwent anterior segment imaging in the nasal, center and temporal areas using the Fourier-domain RTVue-100 OCT (Optovue) before and 4 weeks after conjunctival cauterization, the study said.
Cross-sectional conjunctivochalasis area measurements significantly decreased in all areas after cauterization, with a mean decrease from 0.247 mm² to 0.054 mm² (P < .001), the study authors found.
There were no significant increases in the cross-sectional tear meniscus area as a whole after cauterization, according to the study.
