In order to accurately evaluating macular degeneration, the OCT is highly valuable. This test is necessary before and after cataract surgery, because a pre-knowledge of the patient's condition is a must before the operation, moreover, it helps to make sure of the macular condition in investigations on the causes of patient's incomplete vision one week after surgery because it informs us about the disorders of the various retina and choroid layers that may affect the patient's vision.
Through clinical examination of the eye bottom, only 28% of the lamellar hole was detected by the specified OCT. It should be noted that most of the Vitreoretinal Traction and Epiretinal Membranes are not detected without this device, and it should also be noted that cataract surgery often does not cause such disorders, but the grounds were already provided.
Retinal pathologies, such as vitreomacular traction, lamellar macular hole, and Senile Choroidal Atrophy are most often not detectable in bottom eye examination.
With OCT, mood hyaloid and its relation with macula we can detect that a region has a major role in macular edema and macular degeneration, and is in fact the only means that accurately identifies Choroidal disorders.
Choroidal atrophy is a risk factor for glaucoma, especially when it is accompanied by parapapillary atrophy. These patients will lack a clear vision, even if the macula seems healthy.
myopic chorioretinal degeneration may also be associated with visual impairment.
Sometimes, after cataract surgery, vitrea degeneration may develop or exacerbate and posterior vitreous detachment, which in turn, causes vitreomacular traction or Epimacular membrane progression and exacerbation of symptoms, or even cause macular hole. One week after cataract surgery, 20% of these patients suffered with posterior detachment.
When should OCT be conducted and what points should be followed?
In patients who implant multifocal lens or toric lenses, and incur more expenses they should be informed about the retinal status and chorea.
In patients with no visual impairment or lens opacity.
After retinal photocoagulation, prioritization and retinal detachment an epiretinal membrane may cover macula level. The thickening of the macula region and posterior
