The innermost layer of the eye is called the retina. Its primary function is to process light rays and transmit them to the brain. It converts visual signals into electrical signals, which are sent to the brain via the optic nerve, allowing for visual perception. Damage to this part of the eye can lead to vision loss or blindness. Common retinal conditions include diabetic retinopathy and age-related macular degeneration. Experienced physicians in the retina specialty clinic diagnose and treat these diseases using advanced diagnostic and treatment tools such as OCT, angiography, OCT angiography, retinal lasers, and modern vitrectomy devices. Eye tumors can also pose significant risks, and experienced oncologists at Negah Eye Hospital use their expertise and advanced technology to treat these conditions.
