Intraoperative Optical Coherence Tomography (OCT): A New Frontier in Vitreo-Retinal Surgery

Abstract

Optical coherence tomography, a non-invasive imaging technique is an indispensable tool in the armamentarium of modern day ophthalmologists. With evolution in technology, modern day OCT machines (swept source OCT) are able to provide high resolution images of vitreous, retina, choroid and sclera simultaneously. As a better understanding of various retinal disorders was obtained with the use of OCT, the need for refinement of vitreo-retinal surgery utilizing intra-operative OCT was felt. While earlier versions of intra-operative OCT were hand held, the newer versions are fully integrated with microscope (MIOCT). MIOCT provides spectraldomain OCT (SD-OCT) images while performing the surgery on heads up display. MIOCT has been found to be useful in the management of various disorders such as macular hole, epiretinal membrane, vitreomacular traction syndrome, vitreous hemorrhage and retinal detachment. However the present day intraoperative OCT machines have several limitations, which need to be sorted out before they can be incorporated in the daily practice.

Comprehensive review of surgical microscopes: technology development and medical applications

“… 38 and Kumar et al. 455 reported using RESCAN 700 as a surgical tool to image surgical maneuvers during vitreoretinal surgery. For example, it has the capability to image the anatomical configuration of the scleral wound, determine residual traction membranes in proliferative retinopathy, assess the strength of vitreomacular adhesions in vitreomacular traction, avoid iatrogenic break of myopic retinae in myopic foveoschisis, and avoid inadvertent nerve fiber break by providing real-time imaging of membrane peeling in the cases of macular holes.…”

Оптическая Когерентная Оценка Эффективности Ксенопластики При Макулодистрофии Сетчатки

“…Для этого применяют: сосудорасширяющие препараты; дезагреганты (для предотвращения тромбообразования); комплекс витаминов (чтобы укрепить стенки сосудов сетчатки); биогенные стимуляторы. Наряду с этим применяют физиотерапевтическое лечение, в которое входят: магнитотерапия, лазерная стимуляция сетчатки; электрофорез совместно с препаратами, которые питают ткани глаза [5].…”
