Retinal Venous Occlusion
October 10, 2010 By Leave a Comment
Retinal venous occlusion is among the foremost causes of sudden painless loss of vision and the second most prevalent retinal vascular disease after diabetic retinopathy. The rubric retinal venous obstructive disease includes two primary manifestations: branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO). Although BRVO and CRVO differ in terms of pathophysiology and clinical course, the shared mechanisms for decreased vision include retinal edema, retinal hemorrhage, retinal ischemia, and vitreous hemorrhage. Eighty percent of retinal vein occlusions are BRVO’s[1]. Associations with BRVO include hypertension, cardiovascular disease, increased body mass index by age 20, and glaucoma[2]. The pathophysiology of BRVO typically originates in the retinal vascular anatomy wherein retinal arteries and veins share a common adventitial sheath. As arteriosclerotic changes develop in the arteries, secondary venous compression results in turbulent blood flow leading to endothelial damage and thrombus formation.
Dry Eye – About Dry Eye & Treatment

One of the few potential downsides of living in the beautiful state of Colorado
Dry eye is an extremely common condition, particularly in the semiarid climate of Colorado, and a common chief complaint of patients presenting to our clinic. The symptoms of dry eye range from mild ocular irritation or a sensation of the eyelids feeling heavy, to severe ocular foreign body sensation, blurry vision, and debilitating discomfort. If left untreated, the long term sequelae of dry eye leads to the breakdown of the ocular surface resulting in the potential for corneal scarring, conjunctival inflammation, compromised vision, and ocular pain.

About neovascular glaucoma
Neovascular glaucoma (NVG) is a potentially devastating result of serious underlying ocular and/or systemic diseases. Most cases of NVG are preceded by ischemic disease of the retina, and the subsequent release of diffusible angiogenic factors which promote new blood vessel growth. It is imperative to make the diagnosis early, and then initiate immediate and aggressive treatment. A delayed diagnosis or poor management can result in complete loss of vision, and possibly even loss of the globe itself.
Corneal Collagen Cross-Linking

In the past, when a patient developed keratoconus, a progressive steepening and thinning of the cornea, the patient would be fitted with a contact lens in order to attain adequate visual acuity. As the disease progressed, specialty contact lenses would be fitted. If the patient’s corneal steepening was such that the specialty contacts no longer worked, or the wear time was significantly shortened or corneal abrasions were the norm, the only other alternative was a corneal transplant.
Autologous Serum Tears for the Treatment of Dry Eye (“Keratoconjunctivitis Sicca”)

Keratoconjunctivitis sicca, or dry eye, is a very common chronic condition affecting many of our patients, particularly given the arid region in which We practice. Longitudinal studies regarding the prevalence and incidence of this condition are few. One large study, the Beaver Dam Study, reported a 5-year incidence of l3%.1 The incidence increases with patient age and gender, the use of medications, comorbidities such as collagen vascular disease, and varies by region based on climate.
Flashes and Floaters
October 9, 2009 By 2 Comments
Flashes and floaters are among the most common presenting visual complaints. Multiple etiologies may manifest these symptoms, including uveitis, hemorrhage, migraine, vitreous opacity, and corneal opacity. However, these symptoms are most commonly associated With either a vitreous detachment or a retinal detachment. Differentiating these is only possible With a thorough retinal exam.
The symptoms of floaters exhibit some variability. Patients typically describe mobile, darks specks or spots in their vision, i.e. “the bug I can’t swat.” Variations include stripes, diffuse haze, or a lacy veil. These are a nuisance, but Will slowly fade away. The flashes are much more specific. Peripheral photopsias are described as a rapid flash of light in the extreme periphery of the vision, i.e. “a lightning flash over my shoulder”. These resolve entirely over time. In contrast, visual aura associated with migraines typically cause temporary central visual disruption and flashes.
Chronic Open Angle Glaucoma: What to Know
July 3, 2009 By Leave a Comment
By Gary Belen, M.D.
Glaucoma is an optic neuropathy that produces characteristic structural changes to the optic nerve head, often with correlating visual field defects. It is second only to cataracts as one of the leading causes of blindness in the world. However, as opposed to cataracts, the visual loss sustained from glaucoma is irreversible. In the United States, it is the most frequent cause of blindness in African-Americans, with a higher prevalence, earlier age of onset, and greater sensitivity of optic nerve damage than other conditions. It is the third most frequent cause in Caucasians, following only macular degeneration and diabetic retinopathy. Over two million Americans have glaucoma, with an additional one million people who are unaware that they have the disease. Due to the rapid aging population, the number of Americans with glaucoma is expected to rise to more than three million by the next ten years.
