Yeux kératoconiques "atopiques ou pas"...

[V2F]

D'après cette étude, les caractéristiques des cornées kératoconiques diffèrent sensiblement à l'examen (topo et pachymètrie), chez les patients qui présentent un terrain atopique.

Keratoconus characteristics differ between atopic, non-atopic eyes

Atopic eyes with keratoconus may have different corneal topographic and pachymetric characteristics compared with non-atopic eyes with keratoconus, according to a study by researchers in Turkey. "Atopic keratoconus patients could possibly be evaluated as a separate entity in keratoconus disease," the study authors said.

Vedat Kaya, MD, and colleagues analyzed differences in corneal topographies for 70 keratoconus patients with and without atopy who had not undergone prior surgical interventions. Based on the criteria used in the U.K. Atopy Study Group, 66 eyes of 33 patients had either partial or full atopy and were included in the atopic group. The 74 eyes of the remaining 37 patients without atopy comprised the control group, according to the study.

Patients in the atopic group averaged 27.7 years of age; control patients averaged 26.9 years of age. Central corneal thickness averaged 428.5 µm in the atopic group and 491.8 µm in the control group, the authors reported.

"There was a statistically significant difference between the mean central and thinnest corneal pachymetric readings, the distance of thinnest point to corneal center, anterior and posterior elevation values, distances of the anterior and posterior elevation to the central cornea, and irregularity [indices] in the two groups (P < .05)," they said.

The study is published in the September issue of Cornea.
