Ultrasound Biomicroscopic Examination of Acute Hydrops in Patients With Keratoconus

Anterior Segment Optical Coherence Tomography Features of Acute Corneal Hydrops

“…However, very little is known about the in vivo morphology of the cornea during acute hydrops and how it affects the response to therapy. 13,14 In our previous study, we found that although intracameral C 3 F 8 significantly reduced the duration of corneal edema in eyes with acute corneal hydrops, the effect was widely variable (8.1 6 5.5 weeks). 15 Considering this, we hypothesized that factors such as size of the DM break, depth of the DM detachment, and initial corneal thickness may influence the duration of corneal edema in addition to the effect of any treatment.…”

Spontaneous Resolution of Acute Corneal Hydrops in a Patient With Post-LASIK Ectasia

“…Formation of intrastromal clefts may also be an important factor in hydrops development. 6 Although rare, hydrops is most commonly seen in association with advanced keratoconus (2.6%-2.8%) although it may occur with a greater frequency in rarer ectatic disorders, such as pellucid marginal degeneration (6%-11%) and keratoglobus (11%). 1,7,8 Hydrops is usually considered a self-limited disease because endothelial cell migration adjacent to the tear in the Descemet membrane typically results in corneal deturgescence, scarring, and flattening over a 2-to 4-month period.…”

Apport de l’OCT de segment antérieur « en face » dans le kératocône aigu

“…L'hydrops cornéen ou kératocône aigu est une complication rare mais grave qui peut survenir au cours de l'évolution du kératocône [1,2]. Elle correspond à l'irruption massive d'humeur aqueuse dans le stroma cornéen suite à une rupture de l'endothélio-Descemet avec l'apparition brutale d'un oedème stromal et épithélial [3,4]. L'hydrops cornéen surviendrait chez 2,4 à 3 % des yeux avec un kératocône et bien que spontanément résolutif, il serait responsable d'une diminution de l'acuité visuelle liée à l'opacification cornéenne qui en résulte [3,4].…”
