- Asymptomatic
In asymptomatic diabetic patients, PDR may be a predictor of early cerebral vessel involvement and should lead to investigate brain hemodynamics by screening procedures. © 1997 S. Karger AG, Basel Article / Publication Details First-Page Preview [karger.com]
METHODS: In 51 asymptomatic T1DM patients with, 53 without proliferative retinopathy and 51 controls, right common carotid artery ultrasound was used to assess intima media thickness (cIMT) and distensibility (cD). [ncbi.nlm.nih.gov]
In the initial stages of diabetic retinopathy, patients are generally asymptomatic, but in more advanced stages of the disease patients may experience symptoms that include floaters, distortion, and/or blurred vision. [emedicine.medscape.com]
Asymptomatic During the earliest stages, diabetic retinopathy is often asymptomatic. [docshop.com]
Diabetic Retinopathy Symptoms Nonproliferative Diabetic Retinopathy (NPDR) is often initially asymptomatic. In the early stages of the disease, a patient may not even know that they have any issues. [vrssurgery.com]
Respiratoric
- Cough
Post Operative Restrictions Post-operative restrictions are for 4 weeks after surgery and include: • Anything that creates a Valsalva Maneuvers such as coughing, sneezing, blowing your nose, straining with bowel movements or exertion, and some of the [retinacenternj.com]
Gastrointestinal
- Vomiting
Since fluid can no longer leave the eye through the normal passages, the eye pressure can skyrocket, causing severe eye pain, headache, nausea and vomiting. Permanent vision loss often results when this occurs. [retinacarecenternj.com]
Less common are nausea, vomiting, hypotension, and tachycardia. In ophthalmic literature, the most commonly recognized adverse ocular events are blurred vision, irritation, and conjunctivitis as the drug is secreted in tears. [kjophthal.com]

Cardiovascular
- Vascular Disease
Most cases of CME develop in patients who have had recent eye surgery, such as cataract surgery, as well as patients with diabetic retinopathy, uveitis and retinal vascular disease. [retinacarecenternj.com]
Retinopathy, or retinal vascular disease, can be broadly categorized into proliferative and non-proliferative types. [en.wikipedia.org]
Definition and Pathogenesis Diabetic retinopathy is clinically defined, diagnosed and treated based on the extent of retinal vascular disease detected by ophthalmoscopy. [guidelines.diabetes.ca]
Skin
- Macula
Soon, normal blood vessels can become blocked and may start bleeding and lipid exudates can form in the central retina (macula). [retinacarecenternj.com]
[…] retinopathy [ ret″ĭ-nop´ah-the ] any noninflammatory disease of the retina. central serous retinopathy a usually self-limiting condition marked by acute localized detachment of the neural retina or retinal pigment epithelium in the region of the macula [medical-dictionary.thefreedictionary.com]
Of the remaining 133, 104 (78%) had had focal or grid photocoagulation of the macula. The median time between the documentation of maculopathy before the first PRP treatment session was 16 months (interquartile range 7-36). [ncbi.nlm.nih.gov]
(fovea) caused by leakage of fluid and exudates from damaged capillaries in the center of the macula. [retinacenternj.com]
Ideally the retinal detachment should be repaired prior to the involvement of the macula. If the macula becomes detached, the vision is unlikely to be as good as it was prior to the retinal detachment even with successful surgical re-attachment. [avruc.com]
Eyes
- Blurred Vision
This changes the curvature of the lens, leading to blurred vision. However, once blood sugar levels are controlled, blurred distance vision will improve. [aoa.org]
When NPDR becomes more severe, it may lead to blurred vision, decreased clarity of vision, and fluctuating vision quality. Proliferative Diabetic Retinopathy (PDR) can cause profound visual impairment. [vrssurgery.com]
[…] fragile new blood vessels bleed, blurred vision is sudden. [sharecare.com]
Some patients may be able to view spots or a few specks of blood in their line of vision. Vision may clear without any treatment, but the spots may recur and bleeding may become serious, causing severe blurred vision. [nmceyecare.ae]
However, bleeding can reoccur and cause severely blurred vision. You need to be examined by your eye care professional at the first sign of blurred vision, before more bleeding occurs. [agingcare.com]
- Background Retinopathy
RESEARCH DESIGN AND METHODS: In this case-control study, we compared 81 patients with longstanding (> or =20 years) type 1 diabetes who had nonproliferative (mild or moderate background) retinopathy with 95 patients with diabetes of similar duration and [ncbi.nlm.nih.gov]
If you've had a diabetic eye screening test, you'll be sent a letter stating that you have one of the following: no retinopathy – this means no signs of retinopathy were found and you should attend your next screening appointment in 12 months background [nhs.uk]
You are less likely to develop retinopathy or, if you have mild (background) retinopathy it is less likely to progress to more serious retinopathy, if: Your blood sugar (glucose) level is well controlled. [patient.info]

- Visual Impairment
Eyes with neovascularizations at follow-up were more often visually impaired (VA < 0.5) than eyes without neovascularizations (15/55 versus 1/26; p = 0.016). [ncbi.nlm.nih.gov]
If your vision is affected by retinopathy, you may be eligible for certain benefits and there are a number of tools and aids which help diabetes management easier for people with visual impairments. [diabetes.co.uk]
Retinal Detachment In the final stage of NPDR and the onset of proliferative diabetic retinopathy, severe visual impairment takes place, often accompanied by retinal detachment. [docshop.com]

- Retinal Hemorrhage
The retinopathy in association with malaria fever described so far includes retinal hemorrhages, vessel changes, retinal discoloration/whitening and papilledema. [ncbi.nlm.nih.gov]
These blood vessels are fragile and can cause large hemorrhages in the eye (vitreous hemorrhage). Scar tissue can form on the surface of the retina, leading to retinal detachment. [vrssurgery.com]
Any NVD with vitreous hemorrhage 3. NVE ≥ ½ disc area with vitreous hemorrhage High-risk PDR was also defined as three or more of the following high-risk characteristics (HRC’s): 1. Presence of vitreous hemorrhage or pre-retinal hemorrhage 2. [bu.edu]
These symptoms are typically caused by vitreous hemorrhage or traction retinal detachment. [merckmanuals.com]
Workup
Workup for diabetic retinopathy includes fasting glucose and hemoglobin A1c measurements. (See Workup.) [emedicine.medscape.com]
Treatment
Abstract The National Diabetic Retinopathy Laser Treatment Audit is a prospective survey of laser treatment for diabetic retinopathy throughout the United Kingdom. [ncbi.nlm.nih.gov]
Three studies compared laser treatment to no treatment and two studies compared laser treatment to deferred laser treatment. [cochrane.org]
Prognosis
[…] median age at onset of Type 1 diabetes was 8.4 (interquartile range 4.2-13.3) years in probands and 16.9 (interquartile range 10.2-27.8) years in later-affected siblings (P CONCLUSION: The siblings first affected by Type 1 diabetes had a better long-term prognosis [ncbi.nlm.nih.gov]
The worst prognosis seems to be in age-at-onset group 5–9 years. However, if compared with age at onset 10–14 years, this difference did not reach statistical significance (1.29 [0.98–1.70], P = 0.07). [care.diabetesjournals.org]
In the past, the prognosis for pregnancy in diabetic women with microvascular disease was so poor that many physicians advised avoidance or termination of pregnancy. 2 With the recognition that the level of glycaemia during pregnancy is directly related [bjo.bmj.com]
Etiology
The patient presented 16 months after fetal death of unknown etiology at 26 weeks of gestation with acute visual impairment in both eyes; severe proliferative retinopathy was diagnosed. [ncbi.nlm.nih.gov]
The etiology of this increase involves changes in diet, with higher fat intake, sedentary lifestyle changes, and decreased physical activity. [3, 4] Patients with diabetes often develop ophthalmic complications, such as corneal abnormalities, glaucoma [emedicine.medscape.com]
This can describe etiologies of intraretinal swelling including diabetes, post-surgical macular edema, vein occlusions, and uveitis. [eyeguru.org]
Prolonged hyperglycemia is the major etiologic agent in all of the microvascular complications of diabetes, including diabetic retinopathy. The cellular mechanisms through which hyperglycemia acts currently remain unclear. [retinacenternj.com]

Prevention
Intravitreal injection of blocking antibodies to SDF-1 prevented retinal neovascularization in our murine model, even in the presence of exogenous VEGF. [ncbi.nlm.nih.gov]
Treating proliferative retinopathy Laser photocoagulation surgery helps to prevent new blood vessels from growing, therefore helping to prevent the complications that can result such as haemorrhage or a detached retina. [diabetes.co.uk]
Early diagnosis and treatment are essential in this disease to enhance a final visual outcome of stabilization and prevention of further loss of vision. [medical-dictionary.thefreedictionary.com]
