FORT LAUDERDALE, Fla. — A single retinal thickness analyzer can detect cystoid macular edema in children with uveitis earlier, Saskia Maca said during the International Society of Imaging for the Eye meeting here.

Ms. Maca evaluated 15 children between the ages of 4 and 13 years with a retinal thickness analyzer (RTA). The children suffered from either anterior or intermediate uveitis.

Single scans were done rather than slit lamp or visual acuity tests because of the children’s ages. “Single scans are less invasive and did not scare the children,” Ms. Maca said.

The RTA was conducted with the objective of single scans of the macular region to determine if cystoid macular edema (CME) was present, she said.

In six of the 15 children (40%), CME could be detected using the RTA. In five children, CME was present unilaterally. In the six children where CME was detected, the disease had previously gone undetected and had not been suspected, Ms. Maca added.

“Single scans can be performed in children as young as 3 years old. This enables ophthalmologists to detect macular edema in children at a young enough age to start therapy,” she said.
