Purposes: To study the vitreoretinal junction at the ora serrata (vitreous base) and at the macular region with UBM and OCT respectively in cases of rhegmatogeneous retinal detachment and in the healing period after ab externo surgery. Methods: 47 patients were included in these studies (17 male and 30 female, mean age 52,8 y) . All patients were affected by rhegmatogeneous retinal detachment, without macular involvement. UBM and OCT were performed before as well as 1 and 3 months after the surgical intervention. The following parameters were recorded: (i) modification of inter-space between retina and vitreous measured by UBM at the vitreous base and expressed in millimeter (ii) variation of thickness (micron) and volume (mm3) of macular area as detected by OCT. Results: About 35 % of patients showed at the 1 and 3 months follow-up a remarkable changes of the inter-space between retina and vitreous base (ora serrata) as well as changes of both thickness and volume of the macular area : (i) mean decrease of inter-space between retina and vitreous base was 52 % (ii) mean decrease of the macular thickness was 35 % (iii) mean decrease of the macular volume was 35 % Conclusions: These findings suggested that scleral cerclage may affect not only the vitreous base but also the macular region resulting in increase of both thickness and volume of the underlying retina. Pathophysiologic role of mechanical forces played in the development of rhegmatogeneous retinal detachment will also be discussed.
