What is the grading for diabetic retinopathy?
Grading classification for proliferative DR (R3) The new classification consists of 2 categories – R3A (active proliferative retinopathy) and R3S (stable treated proliferative retinopathy). This allows for urgent attention where disease is active.
Who are classified three types of diabetic retinopathy?
Three-class (normal, NPDR and PDR) classification: Three classes were classified using HEM and MA, hard exudates, and CWS . This method was accurate in classifying the mild, moderate, and severe NPDR stages with an accuracy of 82.6%, 82.6%, and 88.3% respectively.
What is stage 3 diabetic retinopathy?
Stage 3: Severe nonproliferative diabetic retinopathy A larger section of blood vessels in the retina become blocked, causing a significant decrease in blood flow to this area. At this point, the body receives signals to start growing new blood vessels in the retina.
What is R1 diabetic retinopathy?
Background diabetes-related retinopathy (R1): This is a very early stage of retinopathy that is low risk and requires no treatment. People with these changes are screened annually with a photo. Improved blood sugar and blood pressure control are advised as this reduces the chance of worsening eye changes.
What is R2 in diabetic retinopathy?
R2. Severe none-proliferative severe pre-proliferative. None. Previously termed severe pre-proliferative.
What are the two types of diabetic retinopathy?
There are two types of diabetic retinopathy:
- Early diabetic retinopathy. In this more common form — called nonproliferative diabetic retinopathy (NPDR) — new blood vessels aren’t growing (proliferating).
- Advanced diabetic retinopathy.
What are the different types of retinopathy?
This article will discuss the symptoms, causes, and treatments for four major types of retinopathy, including diabetic retinopathy, retinopathy of prematurity, hypertensive retinopathy, and central serous retinopathy.
What is R2 retinopathy?
R2. Moderate none-proliferative, moderate pre-proliferative. None. Previously termed mild pre-proliferative. Extensive Microaneurysm, intraretinal haemorrhage, and hard exudates.
What is moderate nonproliferative retinopathy?
Moderate Nonproliferative Retinopathy At this stage, the blood vessels in your retinas swell. They may not carry blood as well as they used to. These things can cause physical changes to the retina. These changes can lead to diabetic macular edema (DME).
What are different categories of diabetic retinopathy briefly explain?
Diabetic retinopathy falls into two main classes: nonproliferative and proliferative. The word “proliferative” refers to whether or not there is neovascularization (abnormal blood vessel growth) in the retinaEarly disease without neovascularization is called nonproliferative diabetic retinopathy (NPDR).
What does R1 background retinopathy mean?
Is there a consensus on the classification of diabetic retinopathy?
A review of the literature on the classification of diabetic retinopathy shows that a consensus of opinions is not attained. Therefore it is impossible to compare the results of different works. Most of the classifications are based on purely anatomical criteria (ophthalmoscopic or photographic).
What is the international clinical disease severity scale for diabetic retinopathy?
Core tip: The International Clinical Disease Severity Scale for diabetic retinopathy has been proposed to facilitate communication between diabetic care givers. This new classification is simple to use, easy to remember and based on scientific evidence.
What is the standard retinal photo for diabetic retinopathy?
– Standard retinal photo 8A – Nonproliferative diabetic retinopathy – PDR neovascularization disc – PDR neovascularization retin vessels – Vitreous hemorrhage – PDR traction retinal detachment 1 – PDR traction retinal detachment 2 – Retinal blot hemorrhages – Cotton wool spots – Retinal neovascularization – Traction retinal detachment
What is the abbreviation for diabetic retinopathy?
Abbreviations DR = diabetic retinopathy NPDR = none-proliferative retinopathy NVE = new vessels elsewhere
