OCT stands for "Ocular Coherence Tomography". It is a brilliant new technology which allows for a very precise, non-invasive evaluation of the macula (central retina). Exquisite details of retinal structures can not only be seen...but measured very precisely...and monitored for change (improvement or worsening) over time. The most common use of OCT is for the evaluation of macular degeneration. Very subtle collections of fluid or blood can be detected...the OCT is key to the determination of whether additional treatment is or is not required.
Many other problems...such as macular holes, vitreomacular traction, epiretinal membranes and macular edema...are also best evaluated with OCT.
In Ontario...OCT is now covered by OHIP.
