Description
Diabetic retinopathy is a disease manifestation of diabetes. The condition is defined as retinal changes associated with long-term diabetes.

DEFINITION

Diabetes

Diabetes mellitus is a complex, multifactorial and heterogeneous group of disorders characterized by endogenous insulin deficiency and/or insulin resistance.  The disease manifests itself as a state of chronic hyperglycemia with attendant microvascular and macrovascular complications.

Diabetic Retinopathy

This is the most common and most serious ophthalmic manifestation of diabetes mellitus.  It is a microangiopathy affecting the retinal blood vessels, and has features of both microvascular occlusion and leakage.

• Microvascular complication of diabetes that is based on the observation of vascular changes or the presence of abnormal vascular lesions:
• Retinal vasculopathy is a response to hyperglycemia
• Microaneurysms and other vascular leakage (i.e. hard exudates and macular edema)
• Capillary occlusion, neovascularization

• Oxidative stress is a main causative factor in diabetic microangiopathy

• Release of inflammatory proteins, leukostasis, and programmed destruction of endothelial cells and retinal ganglion cells and axons

• Biochemical alteration results in a breakdown in the blood-retinal barrier

NATURAL HISTORY

Structural Damage to the Eye

• Walls of the blood vessels in the retina become fragile and weakened
• Weakened blood vessels have an increase in vascular permeability
• Lipid deposits form in the retinal tissue secondary to chronic edema
• Fluid accumulates in the macula
• Diabetic macular edema develops

Functional Damage to the Eye

• Distorted or blurred vision
• Report seeing spots or floaters in field of view
• Report dark or empty spot in the central vision
• Difficulty seeing at night

DIAGNOSTIC EVALUATION

The main goal of the diagnostic evaluation in a patient with diabetic retinopathy is to accomplish the following:

• Determine the presence or absence of diabetic retinopathy
• Classify the diabetic retinopathy
• Identify and exclude differential diagnosis
• Determine if the retinopathy is clinically significant and/or vision threatening
• Prescribe a treatment program

Patient History

The severity of the symptoms or signs is varied and depends on the level of control the patient has over their diabetes.  Patients can present with the following abnormal symptoms:

• Blurred vision (sudden or gradual)
• Distorted vision (sudden or gradual)
• Difficulty driving at night
• Floaters or dark spots in their field of view

Clinical Appearance of the Retina

The retinal changes associated with diabetic retinopathy include the following:

• Hemorrhages
• Microaneurysms
• Lipid deposits
• Cotton wool spots
• Edema
• Ischemia
• Venous beading
• Intraretinal microvascular abnormalities
• Retinal thickening
• Neovascularization
• Proliferative non-inflammatory degeneration

DIAGNOSTIC TESTS

Fundus Photography

• To document the progress or lack of progress of diabetic retinopathy
• To document the delivery of medical treatment
• To document the response to treatment
• To help plan a treatment program
• Fundus autofluorescence imaging can be used to detect structural abnormalities and predict functional deficits before the defects appear on standard color fundus photography
• Multi-spectral imaging with the Annidis RHA System can be used to detect structural abnormalities and predict functional deficits before the defects appear on standard color fundus photography

		Fundus Autofluorescence Imaging 68-year-old Black female 30-year history of diabetes Fundus autoflourescence imaging of patient in above picture  Imaging technique with SPECTRALIS OCT uses infrared light rather than white light for illumination  Normal retinal tissue shows a uniform gray color (no autofluorescence) A normal macula shows mild hypoautofluorescence secondary to xanthophyll pigment absorbing the signal Hyperautofluorescence indicates photo receptor damage and retinal pigment epithelial dysfunction secondary to accumulated lipofuscin within the cells Advance disease will lead to a loss of autoflourescence (hypoautofluorescence) due to photoreceptor and retinal pigment epithelial cell loss

Retinal Scanning Laser

• To measure the microscopic anatomy of the retina and vitreoretinal interface
• To measure the effectiveness of therapy
• To help in determining the need for ongoing therapy
• To determine the safety of cessation of therapy

		Diabetic Macular Edema 65-year-old Black female 12-year history of diabetes 20/20 in the right eye 20/25 in the left eye Ophthalmoscopy reveals mild non-proliferative diabetic retinopathy with no obvious retinal edema in either eye OCT scan reveals clinically significant diabetic macular edema in the left eye

Visual Field Examination

• Used to assess visual function and determine the size of any associated visual field defects
• Visual field may be affected depending on the size and location of retinal hemorrhaging the extent of the visual field defect depends on size of macular edema

B-Scan Ophthalmic Ultrasound

• A two-dimensional ultrasonic scanning procedure used to produce cross-sectional images of the eye and orbit
• B-scan ophthalmic ultrasound can be used to assess internal structures of the eye when a vitreous hemorrhage prevents proper visualization and examination of the retina
• The test results are used to determine whether the retina is attached or detached

CLASSIFICATION

Diabetic retinopathy is classified into two types:

1.  Non-proliferative diabetic retinopathy 

• Mild
• Moderate
• Severe

		Mild Non-Proliferative Retinopathy Early stage of the disease No symptoms or mild symptoms Retinal blood vessels become fragile and weakened causing tiny abnormal changes called microaneurysms to protrude from the retinal walls Microaneurysms may leak fluid into the retina and produce edema in the tissue Low risk of progression to proliferative retinopathy
		Moderate Non-Proliferative Retinopathy Microaneurysms Some intraretinal hemorrhages Some venous beading Low risk of progression to proliferative retinopathy
		Severe Non-Proliferative Retinopathy Twenty or more intraretinal hemorrhages in four quadrants Definite venous beading in two or more quadrant Prominent intraretinal microvascular abnormalities in one or more quadrants No neovascularization High risk of progression to proliferative retinopathy

2.  Proliferative Diabetic Retinopathy

• Definite neovascularization
• Preretinal hemorrhage
• Vitreous hemorrhage
• Fibrotic proliferation and vitreous scaffolding

DIFFERENTIAL DIAGNOSES

This would include any eye diseases that produce changes in the retinal vasculature such as hemorrhages, microaneurysms, edema, and exudates.

		Hypertensive Retinopathy Lipid andexudative deposits are similar to those seen in early non-proliferative diabetic retinopathy Cotton wool spots are seen in both diabetic retinopathy and hypertensive retinopathy
		Retinal Venous Obstruction Central retinal vein occlusion (CRVO) and Branch retinal vein occlusion (BRVO) can produce retinal hemorrhages similar in appearance, however the onset of CRVO and BRVO are sudden versus diabetic retinopathy is over time
		Retinal Telangectasia Pathologically dilated blood vessels leak fluid into the retinal tissue Exudative formation secondary to fluid retention is similar in appearance to the exudates found in diabetic retinopathy
		Leukemia Ocular manifestations of leukemia can produce the following retinal vessel changes: Microaneurysms Blood vessel dilation Neovacularization Cotton wool spots

TREATMENT OPTIONS

Palliative Treatment

• Change of diet, weight loss and incorporating exercise
• Managing any other medical conditions such as high blood pressure and high cholesterol can help reduce the risk

Pharmacologic Treatment

• Long term control of blood sugar either through oral medication or injection is important for preservation of vision, especially with no signs of diabetic retinopathy or the early stages of it

Surgical Treatment

Laser Therapy Scattered laser treatment, also known as panretinal photocoagulation, can stop the leakage of fluid into the retina

Intraocular Surgery

Vitrectomy — This procedure can is used to remove blood from the vitreous and scar tissue tugging on the retina.
