BACKGROUND: Aim of this study was the investigation of changes of aqueous flare and cells in eyes with retinal detachment.
PATIENTS AND METHODS: We examined 62 eyes of 61 patients with retinal detachment (56 eyes with rhegmatogenous retinal detachment, 6 eyes with traction retinal detachment; 51 eyes without and 11 eyes with clinical signs of proliferative vitreoretinopathy (PVR) stage C) with the laser flare-cell meter (LFCM) and compared the results with clinical findings and with the results of a control group.
RESULTS: The flare values as well as the cell count of all eyes with retinal detachment were significantly elevated (p < 0.0001) in comparison to those of the control group. In eyes with PVR a significant elevation of flare values in comparison to eyes without PVR appeared (p = 0.0052). A slight correlation was found between the extension of the detachment and the flare values and the cell count, respectively. In cases with rhegmatogenous retinal detachment a significant elevation of the cell count was found if the largest break was localized in the upper hemisphere (p = 0.03) or if the macula was affected (p = 0.02). In rhegmatogenous retinal detachment, the cell count correlated slightly with the age of the patients (r = 0.3, p = 0.02), and flare values correlated with the height of the detachment (r = 0.28, p = 0.04).
CONCLUSIONS: Our results demonstrate a breakdown of the blood-ocular barriers in eyes with retinal detachment and an elevation of corpuscular elements in aqueous as manifestations of pseudouveitis. In eyes with PVR the alteration of blood-ocular barriers seems to be more extensive than in eyes without PVR indicating a possible role of the LFCM for early detection of PVR.
