Both clinical and radiological methods can be used for early detection of resorption in OOKP patients; this is influential in preventing serious complications such as extrusion and endophthalmitis. Radiologically, use of either multidetector computed tomography (MDCT) or electron beam tomography (EBT) is valuable in identifying laminar resorption. A novel approach was recently adopted in Sussex Eye Hospital, using volume rendering software in processing previously obtained MDCT images, to calculate volume of the OOKP lamina rather than 2D measurements. We present the results of an observational retrospective case series study to illustrate the use of this approach. We describe how it can be used to calculate percentage change in volume of the lamina over time and how this can be correlated with clinical laminar resorption. We will also discuss further recommendations to build upon this advance.
