Retina
Retina is the innermost light sensitive layer of the eye. It receives the light and converts it into neural signals that are sent to the brain for visual recognition.
Diabetic Retinopathy
Diabetes Mellitus is a systemic disease that affects the retina. Diabetic retinopathy is a major cause of blindness. There are two main types of diabetic retinopathy
1. Proliferative retinopathy — New blood vessels grow on the surface of retina and can lead to bleeding and fibrous proliferation in retina.
2. Edematous retinopathy– There is leakage from small blood vessels that lead to swelling of retina and reduced vision.
All diabetics must undergo a dilated fundus examination every year. Further check-up depends on severity of the retinopathy.
Diagnostic modalties
OCT –Optical Coherence Tomography is used to measure the thickness of the retina and observe the cross sectional images of all layers.
FFA —Fundus Florescein Angiography may need to be done at times to look for ischaemic areas or nreovascalasisation
Treatment
The indication of treatment depends on the severity of the disease.
• Laser is an effective treatment for proliferative retinopathy .It induces involution of the new vessels and prevents recurrent bleeding.
• Intravitreal injection of Anti-VEGF drugs like Avastin ,lucentis, Razumab,Accentrix etc.are given to control the leaking blood vessels and macular edema.
• Vitrectomy surgery may be required for persistent vitreous hemorrhage.
