Diabetic retinopathy is a complication of diabetes that affects eyes. It is caused by damage to the blood vessels of the light-sensitive tissue at the back of the eye (retina). 

At first, diabetic retinopathy may cause no symptoms or only mild vision problems. Eventually, it can cause blindness. 

The condition can develop in anyone who has type 1 or type 2 diabetes. The longer you have diabetes and the less controlled your blood sugar is, the more likely you are to develop this eye complication. 

Treatment depends largely on the type of diabetic retinopathy you have and how severe it is and is geared to slowing or stopping progression of the condition.  Treatment can include the following:  

  • Laser treatment that can stop or slow the leakage of blood and fluid in the eye, or it could shrink the abnormal blood vessels  
  • Surgery, called a vitrectomy, that would remove blood from the middle of the eye (the vitreous) or remove tissue that is tugging on the retina. 
  • Injections into the eye with a medication called anti-VEGF therapy that helps to stop growth of new blood vessels by blocking the effects of growth signals the body sends to generate new blood vessels  

Your doctor may recommend any of the treatments alone or in combination with one another, depending on your condition.

Surgery and treatment often slows or stops the progression of diabetic retinopathy, but it's not a cure. Because diabetes is a lifelong condition, future retinal damage and vision loss are still possible. 

Even after treatment for diabetic retinopathy, you'll need regular eye exams. At some point, additional treatment may be recommended.

Presumed Ocular Histoplasmosis Syndrome (POHS) causes atrophy (wasting) around the optic nerve and multiple scars, called histo spots, in the choroid. These symptoms are accompanied by new blood vessel growth (neovascularization) that starts adjacent to a histo spot. Histoplasmosis is a disease caused by Histoplasma capsulatum (H. capsulatum), a soil fungus prevalent in certain parts of the American continent, in particular the Ohio and Mississippi River valleys.



Histo spots (Figure 1) are considered the earliest stage of the disease. Less than 5% of individuals with histo spots will develop neovasculization in the central macula (at the middle of the retina). Because the histo spots themselves usually do not cause symptoms, patients typically do not develop symptoms until neovascularization grows in the central macula. Symptoms include painless, progressive blurring of central vision and wavy vision (metamorphosia), which can be sudden or develop slowly.

Diagnostic Testing

 Ocular coherence tomography (OCT) and fluorescein angiography (FA) are performed to evaluate for neovascularization in patients who visit their doctor with symptoms of visual loss (Figure 2).

Treatment and Prognosis

Treatment is generally required only when there is neovascularization. Given that H. capsulatum does not seem to play a direct role in the development of POHS, antifungal agents are not used to treat POHS. However, injections of medications that inhibit neovascularization are recommended. These medications include bevacizumab (Avastin® ), ranibizumab (Lucentis® ) and aflibercept (Eylea® ). Prior to injection, the eye is given an anesthetic drop or gel and is cleaned with povidone iodine; the injection generally causes minimal, if any, pain. Injections are initially administered monthly until the neovascularization improves, as confirmed by OCT or FA. If neovascularization is treated early, before advanced scarring develops in the central macula, the prognosis for vision is generally good.

What is a CRAO?

When one of the vessels that carries blood to your eye’s retina gets blocked, it can cause you to lose your eyesight. This problem often happens suddenly and without any pain. This is called a Central Retinal Artery Occlusion (CRAO).

Your retina is the layer of nerve tissue at the back of your inner eye that senses light. Like a tiny video camera, your retina turns images into electrical signals. Your optic nerve carries these signals to your brain. If a blockage of a blood vessel happens in your retina, it can be very serious. The blockage usually comes from a blood clot or cholesterol deposit in your blood vessel.  


The signs of CRAO are easy to spot.

  • Sudden blindness in one of your eyes 
  • Sudden, complete blurring of eyesight in one eye 
  • Steady loss of eyesight in one eye over a few weeks 

The symptoms may last a few seconds or minutes. 


Like other vascular blockages, CRAO is a serious condition, and you should seek prompt medical attention. If a blood clot breaks free and moves to the brain, it could cause a stroke.

What is Retinopathy of Prematurity (ROP)?

  1. ROP is a retinopathy eye disease that can affect premature infants born weighing less than 1250 grams or before 31 weeks of gestation. Abnormal blood vessel growth can cause bleeding and scarring in the eye, and in the most severe cases, lead to retinal detachments with potentially permanent vision loss. 
  2. ROP is an eye disease that arises as a result of incomplete development of the retina (the light-sensing tissue that lines the inside of the back of the eye).  Babies who are born before 32 weeks of gestation (I.e., 2 or more months premature) or with a birth weight less than 3 pounds are most at risk.  Incomplete retinal development may lead to the growth of abnormal blood vessels, which in turn can bleed or scar.   If not diagnosed and appropriately treated, ROP can lead to permanent vision loss or blindness due to retinal detachment.  Between 500 and 1000 infants go blind from ROP in the United States each year.  The rates of vision loss are higher in poorer countries. 

ROP- Left Eye


How is ROP diagnosed? 

  1. Fortunately, the vast majority of premature infants, when cared for by experienced specialists, will not suffer significant vision loss from ROP. Evaluation of premature infants for ROP is performed by an ophthalmologist, typically in the Neonatal Intensive Care Unit (NICU) within a healthcare facility or hospital, or sometimes in the office as an outpatient. The ophthalmologist performs a retinal exam through dilated pupils to assess the development of the retina. 
  1. Evidence-based guidelines have been established that determine when to begin exams, how frequently to continue exams, and when it is safe to stop.  Typically, exams are repeated routinely until retinal vessel development has reached satisfactory maturity or the baby has achieved an age by which ROP is no longer seen. In some cases, the ophthalmologist may decide treatment is necessary based on these exam findings. 


Can ROP be treated? 

In experienced hands, the chance of blindness from ROP is exceedingly low.  The conventional treatment is laser surgery to the retina, to induce regression of abnormal blood vessels.  In some cases, injections of special medication (so-called anti-VEGF medication) into the eye are used for the same purpose.  The choice and timing of these treatments are determined by the severity of the ROP and the overall health of the infant.   In severe cases, more advanced retinal surgery may be required to repair retinal detachment. 


Does ROP end in infancy? 

Unfortunately, ROP is a lifelong disease.  While the acute risks can be controlled within the first few months of life, premature infants are at a higher lifelong risk for myopia, strabismus, cataract, glaucoma, and retinal detachment.  For this reason, these children should be seen regularly by an optometrist or ophthalmologist familiar with these potential complications.

What is the Retina?
The retina is a light-sensitive tissue lining the back of the eye, it can be compared to the film of the camera.
It converts light rays into electrical impulses that travel through the optic nerve to our brain where they are interpreted as the images we see.
A healthy, intact retina is key to clear vision.

What is Central Serous Retinopathy?
Central serous retinopathy (CSR) is a condition in which fluid accumulates underneath the retina in the central macula, causing vision loss.

For unknown reasons, tiny areas of the retinal pigment epithelium (RPE), a layer of cells under the retina, become defective. Fluid builds up and accumulates under the RPE, much as liquid in a blister collects under the skin. As a result, a small detachment forms under the retina, causing vision to become distorted.

CSR usually occurs in one eye and can affect men or women. The cause of CSR is not fully understood, but there are several factors that are more common in those who develop the condition.

  • Men 30-50 years of age
  • Stress
  • People with the “Type A” personality
  • Steroid Use (e.g., prescription medication, skin creams, joint injections, nasal sprays, inhalants, or performance enhancers)

Changes are most often confined to the macula, the central part of the retina responsible for our central vision. With that said, patients will often experience loss of central vision, central distortion, decreased color vision, or a central blind spot. Patients may also notice objects may appear farther away than what they really are.


To understand if you have developed central serous retinopathy, you will need to see your regular eye doctor or a retina specialist for examination and testing.

CSR is diagnosed by dilated eye examination and confirmed through specialized testing such as optical coherence tomography (OCT) and fluorescein angiography (FA).

CSR Fluorescein Angiogram

CSR Fundus Photo


The fluorescein angiography requires the injection of a mild mineral based dye injected through the vein in your arm. Photographs are taken as the dye passes through the retinal vessels, highlighting the abnormal areas.
The OCT will take a cross-section image of the retina, showing retinal thickness and any swelling of the retina.


Treatment Talk:
Most cases of CSR are managed by observation of the condition, as CSR often resolves without treatment within several weeks or months, and your eyesight often returns to normal or almost normal once the swelling subsides. Patients taking steroids may need to discontinue or modify dosages, if possible and only after consulting their physician.

Recovery does require time and patience, as improved vision typically occurs within 1-4 months. However, there are instances when treatment may be desirable. These instances include when there is persistent swelling or significantly reduced visual acuity.

Patients with chronic CSR may need laser treatment, oral medication, or eye injections which may prevent significant loss of vision.

● Photodynamic therapy or “cold” laser

● Medication (oral, injection in arm, injection in eye)

● Thermal laser treatment to seal leaking blood vessels.

Retinal Vein Occlusion

Retinal Vein Occlusion (RVO) happens when a retinal vein becomes blocked or clogged. It occurs most commonly in patients with medical conditions such as high blood pressure, diabetes, high cholesterol and other health problems that affect blood flow. RVO can range in severity from subtle, with no visual symptoms noticed, to severe, with significant decreased vision. Two common causes of vision loss resulting from RVO are macular edema (swelling) and retinal neovascularization (abnormal blood vessel growth). In severe cases, neovascularization can cause the pressure in the eye to go up to a dangerous level. Although there is no way to unblock a retinal vein, there are available treatments for including anti-VEGF injections and laser. If left untreated, a retinal vein occlusion can lead to permanent vision loss.  If you have any vision changes or symptoms, it is important to follow up with your eye doctor quickly.

About the Injections:

An intravitreal injection is an in-office procedure typically performed by a retinal specialist.  Eye injections are used to treat many serious retinal conditions that could lead to vision loss by introducing a small dose of medicine directly into the gel-filled center of the eye called the vitreous, using a syringe with a very tiny needle. 

The thought of an eye injection sounds terrifying to most. However, it is a very quick procedure & virtually painless. The injection is given in the white part of the eye only after the eye has been numbed and sterilized.  

After an eye injection, your vision maybe somewhat blurry, so it is recommended to arrange transportation home.  It is also common to see floating spots or bubbles in the injected eye for a day or two and do resolve on their own. 

The anesthetic and sterilizing drop that are used can be very drying to the cornea (surface of the eye).  After treatment, the eye may feel irritated once the numbing has worn off. It is very important to avoid rubbing the eye to lessen the risk of a scratch or abrasion. 

While there are other complications or risk associated with receiving an injection, these treatments have been proven to be very effective in managing illnesses that could compromise the vision. The number of scheduled treatments is based on the patient’s specific eye disease and response to the medication used.   

For more information and videos about intravitreal eye injection and/or other treatment options please consult your retina specialist or visit & Diseases of the Retina to learn more.

 Ocular Oncology is the diagnosis and treatment of a variety of eye tumors and cancers. As part of Ocular Melanoma Awareness month, Tennessee Retina wants to encourage others to learn about this rare condition. #ocularmelanoma 

 Uveal Melanoma is cancer that started as a mole in one of the structures of the uvea (iris, choroid, ciliary body). The development of a mole (also called a "nevus") is very normal and occurs in about 7% of all people. These moles are usually benign, but there are some moles that contain cells which mutate (change their DNA and their cellular properties).  This mutation can lead to uncontrolled growth and the development of cancer. 

Eye Cancer Symptoms and Signs: 
Many times, an eye doctor finds melanoma during a regular eye examination. Uveal melanoma is a rare cancer and behaves differently than most other cancers. Uveal melanoma is unique in that it rarely grows to surrounding tissue. When it does spread, it spreads through the bloodstream. The most common symptom of a uveal melanoma is a painless loss of vision, but people with eye cancer may experience other symptoms or signs: 

  • Having trouble seeing
  • Losing part of the field of vision
  • Seeing flashes of light 
  • Seeing spots, squiggly lines, or floating objects (floaters) 
  • Having a dark spot on the iris 

Some people with eye cancer do not show any of these symptoms, and these symptoms may be caused by a medical condition that is not cancer. If you are concerned about one or more of the symptoms on this list, please talk with your eye doctor.  

The most common therapy for uveal melanoma is radiation, which needs to be applied in a very specific way to a very small space. It is usually accomplished through a surgical procedure called Plaque Brachytherapy, where a very small radioactive device is placed in the needed area to deliver the radiation and is then removed in a second surgery.  

About our Team: 
We strive to provide our patients with sincere care and to be available through the whole process to answer any questions you may have. Our care starts with our remarkable Oncology Team- Dr. David Reichstein and the Oncology Coordinators.

What does 20/20 actually mean?

20/20 vision is not perfect vision. However, it does mean that an individual has eyesight which is 
more or less statistically average or "normal." A person can also have 20/15 vision, which is sharper than 
average. The goal of glasses, contacts, or corrective surgery is to bring a person's vision as close to 
20/20 as possible. 

20/20 vision is a term used to express the clarity or sharpness of vision measured at a distance of 20 feet. 
For example, if you have 20/100 vision, it means that you must be as close as 20 feet to see what a 
person with unimpaired vision can see at 100 feet. Fortunately, in our world of technology, there are mulitple resources and tools available to aid those who experience "low vision" due to various 
conditions. Start your search with our list of links.
