Iran’s retinal treatment technology equals developed states

Tehran, IRNA - With the new methods now employed in the field of eye diseases and retinal disorders, Iran is in the same place as the advanced countries of the world, said the head of Ophthalmology Department at Iran University of Medical Sciences (IUMS) on Friday.


Retina is a light-sensitive neural tissue that forms a thin layer inside the posterior part of the eye. It transforms the light into neural signals and sends them to the brain. So the retina plays a key role in the visual process.

This
keypartofvision is affected by diseases such as diabetes, eye injuries, or age-related disorders that require immediate treatment.

Previously, retinal disorders treatment was difficult, but with the scientific advances and the development of new technology-based firms (NTBF), it is becoming easier, said Khalil Qasemi Falavarjani who is also an associate professor of ophthalmology at IUMS.

He added there have been many advances in curing retinal disorders in terms of both diagnosis and treatment worldwide.

“Although a part of these findings cannot be applied clinically, they pave the way for future improvements.”

Qasemi Falavarjani said one of these findings pertaining to diagnostic methods applied for retinal diseases is a new imaging method which provides the doctor with diagnostic ability equivalent to retinal sampling. It also helps the physician find the causes of the disease.

“Being non-invasive, new imaging techniques eliminate the need for contrast
agent, and demonstrate vascular images and their changes by image analysis procedures.”

The new non-invasive technique is fast, he said, adding that wide-field imaging is another imaging method.

In traditional ways, 'we could see a limited area of the retina, or at most we would assemble a variety of images, sticking them together and making a final one with spending a great deal of time', he added.

“But new approaches provide us with an area twice as large as the area provided in previous techniques. It helps us easily diagnose and treat illnesses that have occurred on both sides of the retina.”

Removing the distortion in optic imaging and getting very precise images of even one cell is another feature of this technology, he said, adding, “Previously, we used to cut the cell and examine it under a microscope, but the new technology is so precise that we can examine the cells also.”

Qasemi Falavarjani suggested gene therapy as another therapeutic method, adding that the first retinal treatment through gene therapy was approved by the US last year, and is now being applied.

“This method is quite new, but we hope it will be applied for congenital or acquired retinal diseases in the near future.”

He noted that there are some other techniques that remove the necessity for surgeries. For instance, computer chips or artificial retina are placed for blind people giving them the ability to see one light.

“This technique is already being applied in Iran, but unfortunately it is very expensive and we hope to have new versions with lower prices in the coming years.”

Facilitating the process of surgery, some other ophthalmic surgical technologies help the surgeon see three-dimensional images, the ophthalmologist added.

Many of these techniques are applied every day In Iran and in some other cases 'we are negotiating with some countries to import the techniques' and equipment, he concluded.
