  • Treating the Pregnant Glaucoma Patient

    Posted on February 25 2016


    More women are becoming pregnant later in life. With age comes the greater chance of health issues, including eye diseases. Today, ophthalmologists are treating a large number of women who have glaucoma while pregnant. Many patients with congenital, pediatric or juvenile-onset glaucoma become adults wishing to start a family. The challenge in treating this group is balancing the risk to the mother’s vision against the potential for harm to the fetus. It is very important for ophthalmologists to manage these risks and to understand the needs of these patients.

  • Double Vision

    Posted on December 04 2014


    Double vision is the observation of two images of a single object seen adjacent to each other, or overlapping. The medical term for double vision is diplopia. Polyplopia is the perception of three or more images of a single object. There are several causes of double vision, therefore it is important for your eye doctor to carefully review your history and examination to determine the cause and initiate appropriate treatment. A thorough evaluation of double vision begins with a detailed history of the diplopia; including with it was a gradual or sudden onset. Duration, frequency and noting any associated symptoms also should be noted during the evaluation.

  • AMD & Nutrition

    Posted on November 26 2014


    Age-related macular degeneration (AMD) is the chief cause of blindness for people ages 55 and older in the United States. A rising number of data suggest that nutritional intake of antioxidants- including lutein , zeaxanthin, and omega-3 fatty acids- may help decrease the risk of AMD and help improve vision. Eye health professionals can play an important role in educating patients about the power of nutrition. Since the body is unable to produce these antioxidants , lutein and zeaxanthin must come from dietary intake or from a form of supplements. Some studies suggest that participants who took the AREDS formulation with lutein and zeaxanthin had an 18 percent reduced risk of developing advanced AMD over a 5 year study, and participants who had low levels and intake before the study began were 25 percent less likely to develop advanced AMD compared to participants with similar dietary intake who were not taking lutein and zeaxanthin supplements.

  • Building Valuable Skills in Opthalmic Imaging

    Posted on October 20 2014


    Opthalmic imaging has played an important role as an addition to a patients ophthalmic examination. Imaging has become a critical component of a comprehensive exam due to new technology and treatment options. Fundus photography, optical coherence tomography and fundus autofluorescence results are commonly used as a basis for treatment plans in glaucoma, diabetic retinopathy and age-related macular degeneration. Opthalmic personnel with imaging skills are increasingly in demand and learning these skills can expand your role as a valued member of any eye care team. In addition to the useful and technical aspects of imaging, good assessment and communication skills can also lead to better image quality. Blinking, focusing and overexposure all can be factors in obtaining clear and accurate photos. Learning to judge the images on the capture monitor can help discover any artifacts or problems.

  • Evaluating and managing post-op CME

    Posted on October 13 2014


    Pseudophakic CME typically happens two to twelve weeks following cataract surgery, although in rare cases it may present months afterwards. The peak incidence of visually important CME is four to six weeks after cataract surgery. Two patient populations at particular high risk for developing postoperative CME are those with a history of uveitis or uncontrolled diabetes and diabetic retinopathy. Postoperative rates of CME in patients with uveitis, even when controlled preoperatively, can be larger than thirty-five percent. CME in patients with diabetes, especially those with preexisting DR and DME, has been reported to be as high as fifty-five percent. Once you have established a diagnosis of pseudophakic CME, appropriate management hinges on identifying an underlying cause, if any. Pseudophakic CME is a main cause of decreased visual acuity following uncomplicated cataract surgery and can be the source of significant patient morbidity.

  • Summer is peak season for environmental dry eye triggers

    Posted on September 19 2014


    Ophthalmologists have more tools than ever to manage the millions of patients who reportedly suffer from dry eye but one of the most basic causes is many times overlooked: environmental triggers. Dry eye is hugely impacted by the environment, so that’s the first thing doctors can address before even discussing medications or other types of treatment. Patients should be conscious of the fact that they may have to change their lifestyle. Patients should be made aware the importance of wearing sunglasses. Sunglasses are very protective to the eyes. One should also take frequent breaks when reading or using computers or tablets.

  • 3 types of Astigmatism

    Posted on September 10 2014


    Astigmatism is an optical defect in which vision is blurred due to the inability of the optics of the eye to focus a point object into a sharp focused image on the retina. This may be due to an irregular or toric curvature of the cornea or lens. The two types of astigmatism are regular and irregular. Irregular astigmatism is often caused by a corneal scar or scattering in the crystalline lens, and cannot be corrected by standard spectacle lenses, but can be corrected by contact lenses. The more common regular astigmatism arising from either the cornea or crystalline lens can be corrected by eyeglasses or toric lenses. A ‘toric’ surface resembles a section of the surface of a Rugby ball or a doughnut where there are two regular radii, one smaller than the other one. This optical shape gives rise to astigmatism in the eye.

  • Two different perspectives of the posterior segment SD-OCT and Cameras

    Posted on August 25 2014


    he use of the camera to document the condition of the eye dates back to the earliest days of photography. Today we commonly use two different, but complementary, technologies to document the ocular fundus: fundus photography and optical coherence tomography (OCT). In imaging the fundus, our goal is to document anatomic structures that can be measured in microns, with enough detail for physicians to make diagnostic decisions. All this must be done through the pupil. Each of these instruments provides a different perspective of the posterior segment. Fundus Cameras The fundus camera is a horizontally mounted instrument with an internal electronic flash and an attached camera or digital sensor.
