A choroidial nevus represents an accumulation of pigmented cells in the choroid. Choroidial nevi present no symptoms and will usually have no affect on vision.diabetic_retinopathy_descriptiontrue1381265587209u0118697Diabetic Retinopathy DescriptionDiabetic Retinopathy Description/moran/patient_care/videos/retinal_diseases/diabetic_retinopathy_descriptionHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/diabetic_retinopathy_descriptionu01351601330535493473u03145801394744044428uNID'sstakeView Video One form of diabetic retinopathy is called non-proliferative diabetic retinopathy, or NPDR. NDPR occurs when diabetes damages small blood vessels within the retina. These vessels start to leak both fluid and blood, gradually causing the retina to thicken or swell. Over time, the swelling, or edema, thickens the retina causing the vision to become blurred.diabetic_retinopathy_npdrtrue1381265587209u0118697Diabetic Retinopathy NPDRDiabetic Retinopathy NPDR/moran/patient_care/videos/retinal_diseases/diabetic_retinopathy_npdrHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/diabetic_retinopathy_npdru01351601330537432354u03145801394744089913uNID'sstakeView Video One form of diabetic retinopathy is called non-proliferative diabetic retinopathy, or NPDR.

This can result in bleeding, scarring, and contraction of the vitreous, which may lead to retinal detachment. PDR can cause severe vision problems, and it can even lead to blindness. It must be treated as soon as possible.macular_degeneration_descriptiontrue1381265587209u0118697Macular Degeneration DescriptionMacular Degeneration Description/moran/patient_care/videos/retinal_diseases/macular_degeneration_descriptionHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/macular_degeneration_descriptionu01351601330538103992u03145801394744172972uNID'sstakeView Video Age-related macular degeneration, also called AMD, is the deterioration of the center of the retina called the macula. The macula is the part of the retina which is responsible for our central vision and our ability to see color and fine detail when looking directly at an object. Age-related macular degeneration or AMD is the most common cause of vision loss in people over the age of 55. In the early stages of AMD, there is little or no vision loss. As the disease advances, images can become blurred, distorted, or a dark or empty area can appear in the center of the vision. AMD does not cause total blindness because side vision is not affected. There is some good news relating to macular degeneration. With regular checkups, early diagnosis, and new treatment options, doctors are now able to prevent or minimize the damage that age-related macular degeneration can cause to vision.macular_degeneration_drytrue1381265587209u0118697Macular Degeneration Dry FormMacular Degeneration Dry Form/moran/patient_care/videos/retinal_diseases/macular_degeneration_dryHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/macular_degeneration_dryu01351601330977725956u03145801394744210280uNID'sstakeView Video The most common form of age-related macular degeneration is called the dry form. This form of the disease affects up to 90 percent of AMD patients. In the early stages of dry AMD, tiny deposits of “drusen,” start appearing within the retina. These drusen may be so insignificant that the patient has few, if any, outward symptoms and no vision loss. As dry AMD progresses, more disruptive drusen begin to appear. As the size and number of drusen increase, patients may begin to notice a small, dark spot in their central vision, causing them problems while reading or driving at night. Drusen alone are not proof of macular degeneration, but they are an important warning sign. It is critical for patients to understand that as dry AMD progresses, it can turn into the more severe form called wet AMD.macular_degeneration_symptomstrue1381265587209u0118697Macular Degeneration SymptomsMacular Degeneration Symptoms/moran/patient_care/videos/retinal_diseases/macular_degeneration_symptomsHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/macular_degeneration_symptomsu01351601330977681158u03145801394744240661uNID'sstakeView Video The most significant symptom of macular degeneration is blurred or distorted central vision. Over time, macular degeneration can affect vision by forming a blurred, darkened, or empty area in the center of vision, or it can distort one’s surroundings, most noticeably in the appearance of straight lines. Macular degeneration may also cause colors to become less vivid. Blurred or distorted central vision can cause an inability to perform tasks that require precision, like driving a car. Fortunately, this disease does not cause total blindness because side vision is not affected. If macular degeneration occurs in only one eye, the symptoms of the disease may not be noticed right away, as the “good” eye compensates for the “bad” eye. It is essential to take these symptoms seriously and to speak with an eye care professional immediately if they are developed.macular_degeneration_wettrue1381265587209u0118697Macular Degeneration Wet FormMacular Degeneration Wet Form/moran/patient_care/videos/retinal_diseases/macular_degeneration_wetHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/macular_degeneration_wetu01351601330977805708u03145801394744272976uNID'sstakeView Video A less common but more serious form of age-related macular degeneration (AMD) is called the “wet form.” This form of the disease affects about 10 percent of AMD patients. In the wet form of AMD, abnormal blood vessels begin to develop underneath the retina. These abnormal blood vessels are unusually delicate and may bleed or leak fluid. This fluid builds up beneath the retina, causing it to bulge or lift up from the back of the eye. The eye is damaged as a result, causing central vision to appear blurred, wavy, or distorted. Wet AMD can progress rapidly, leading to severe vision problems in the affected eye and causing permanent vision loss. Early diagnosis of wet AMD is critical. If caught early, treatment options exist, which may delay or reduce damage to the eye and decrease the severity of vision loss.macular_edematrue1381265587209u0118697Macular EdemaMacular Edema/moran/patient_care/videos/retinal_diseases/macular_edemaHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/macular_edemau01351601330537737969u03145801394744314606uNID'sstakeView Video Macular edema is a condition that occurs when fluid builds up within the macular, the central area of the retina most critical for vision. The buildup of fluid causes the macula to swell, disrupting its normal shape. This results to damage of vision. The symptoms of macular edema include blurred vision, distortion of images, missing areas, or a change of contrast in vision. Left untreated, the swelling can cause these vision problems to progressively worsen. If any of these vision problems occur, speak with an eye care professional immediately.macular_puckertrue1381265587209u0118697Macular PuckerMacular Pucker/moran/patient_care/videos/retinal_diseases/macular_puckerHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/macular_puckeru01351601330537817096u03145801394744353382uNID'sstakeView Video The macula is the area of the retina that is responsible for clear vision. As a person ages, the vitreous inside of the eye begins to shrink. When this occurs in the macular area, the retina initiates a healing response with a migration of cells found within the retina itself. These cells form a thin layer of scar tissue known as a macular pucker or epiretinal membrane.retinal_detachmenttrue1381265587209u0118697Retinal DectachmentRetinal Detachment/moran/patient_care/videos/retinal_diseases/retinal_detachmentHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/retinal_detachmentu01351601330538012740u03145801394744390160uNID'sstakeView Video A retinal detachment occurs when the retina’s layers separate. Any portion of the retina that is detached cannot send visual signals to the brain. If left untreated, retinal detachment can cause devastating damage to an individual’s vision. Retinal detachment is considered an ocular emergency that requires immediate medical attention.retinal_holestrue1381265587209u0118697Retinal HolesRetinal Holes/moran/patient_care/videos/retinal_diseases/retinal_holesHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/retinal_holesu01351601330537934770u03145801394744418059uNID'sstakeView Video Over the course of an individual’s lifetime, the vitreous inside of the eye shrinks. As it continues to shrink, a small portion of retinal tissue may be torn off of the retina, leading to a retinal hole. If left untreated, most retinal holes will not harm your eyesight, but in some cases, they can lead to a serious condition called retinal detachment.retinal_teartrue1381265587209u0118697Retinal TearRetinal Tear/moran/patient_care/videos/retinal_diseases/retinal_tearHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/retinal_tearu01351601330537871550u03145801394744455071uNID'sstakeView Video Over the course of an individual’s lifetime, the vitreous inside of the eye shrinks. As it continues to shrink, a portion of retinal tissue may stay attached to the vitreous, leading to a retinal tear. If left untreated, a tear may lead to retinal detachment. With treatment, the damage usually can be repaired.vitreous_detachmenttrue1381265587209u0118697Vitreous DetachmentVitreous Detachment/moran/patient_care/videos/retinal_diseases/vitreous_detachmentHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/vitreous_detachmentu01351601330977604374u03145801394744483688uNID'sstakeView Video As we age, the vitreous inside the eye tends to shrink and may eventually separate from the inside surface of the eye. This is called a posterior vitreous detachment or PVD. When the vitreous pulls free from the eye, it is often accompanied by flashes of light and appearances of tiny black spots in the vision. In general, PVDs are not dangerous, but in certain cases they can lead to more serious conditions. If left untreated, these conditions can lead to vision loss and may also lead to blindness. It is suggested that anyone with symptoms of a posterior vitreous detachment should have an eye examination immediately to make sure that a more serious problem is not present.vitreous_floaterstrue1381265587209u0118697Vitreous FloatersVitreous Floaters/moran/patient_care/videos/retinal_diseases/vitreous_floatersHealth Caresite://Health Care/moran/patient_care/videos/retinal_diseases/vitreous_floatersu01351601330977476106u03145801394744510527uNID'sstakeView Video Small specks or clouds moving in your field of vision are called floaters. Most floaters are not dangerous and are caused by tiny pieces of tissue inside of the eye. When light hits these pieces of tissue, it creates shadows on the retina that appear to float across your field of vision. It may appear that these specks are on the front surface of your eye, but they are actually inside. In most cases, floaters are no cause for alarm and no treatment is necessary; however, a sudden increase in new floaters may indicate a problem, and an eye examination is recommended if this occurs.
