Keratoconus is a progressive eye disease in which the cornea thins and bulges into a cone-like shape. This causes vision distortion and blurriness, which occurs in one or both eyes and often begins during a person’s teens or early 20s. Treatment includes rigid contact lenses. This photo shows the contact lens touching the cornea, causing discomfort and a lens that moves too much.
All cataract surgery causes some damage to the corneal endothelial cells. Most corneas recover quickly, within 1 week. However, occasionally, after cataract surgery, the endothelial cells don’t function well enough to keep the cornea clear, causing poor vision and often discomfort. In this case, it takes a few months to recover. Anti-inflammatory eye drops every 2 hours can help.
A police cop pulled over my patient, saw his red eye, and questioned him for DUI. Did you know that bloodshot and “glassy” looking eyes are associated with alcohol consumption?
Episcleritis is a relatively common, benign, and self-limited cause of red eye. It is caused by inflammation of the episcleral tissues. A 2013 study estimated incidence of episcleritis as 41.0 per 100,000 per year and prevalence at 52.6.
I prescribed anti-inflammatory eye drops to help with the redness and swelling.
Optic nerve drusen are abnormal globular collections of protein and calcium salts in the optic nerve. They are often present in both eyes, but sometimes occur only in one eye. Rarely, peripheral vision loss may occur slowly, but is so minimal that it is not noticeable. Visual field exams may be performed to monitor for decreased peripheral vision in older children. Another rare complication from optic nerve drusen is choroidal neovascular membrane. This is a collection ofabnormal blood vessels which grow beneath the retina near the optic nerve. Yearly dilated eye examinations are recommended to monitor for any changes.
My in-office nursery is now officially my pre-testing room! To my staff and my patients, thanks so much for your loyalty. It’s been an honor to serve this community for the past 20 years. This community rocks!
Small 1-2 mm, chalky, yellow-white lesions on the inside of your eye may be conjunctival concretions. Treatment is usually unnecessary if you are not experiencing symptoms. They can often be removed with needlepoint forceps or a 30 gauge needle. They can also be removed surgically.
There are numerous benign growths that can afflict the eyelid region. If they are bothersome or suspicious, they can be removed. Usually, they do not need treatment.
Yes! Because you can avoid a corneal ulcer, which is caused by a bacterial infection of the cornea. Extending the life of your weekly and monthly lenses, and wearing them for too many hours are often the culprits. A corneal ulcer is a painful open sore on the clear front surface of the eye that can cause loss of vision and even blindness.
If you are a contact lens wearer, you can avoid a corneal ulcer with good hygiene such as washing your hands before handling lenses and following other safety tips. Daily disposable lenses are the recommended choice!
Severe retinal damage after a blunt eye trauma caused by a firearm resulted in permanent vision loss. Safety eye wear was prescribed to protect the other eye. So important!
A patient came in for a 2nd opinion on a surgical recommendation. An epiretinal membrane is a thin sheet of fibrous tissue that can develop on the surface of the macula. It is sometimes called a macular pucker, premacular fibrosis, surface wrinkling retinopathy or cellophane maculopathy. If the vision is not significantly impacted, surgical intervention is not required. However, if vision is affected, a vitrectomy is recommended.
Vitreoretinal surgical and laser approaches can restore, preserve and enhance vision for many eye conditions such as certain types of age-related macular degeneration, diabetic retinopathy, diabetic vitreous hemorrhage, macular hole, a detached retina, epiretinal membrane and CMV retinitis.
Keratoconus is an eye condition where the cornea thins and bulges into a cone-like shape. This causes distorted, blurry vision which cannot be corrected with spectacle glasses. Rigid contact lenses are the only way to correct this astigmatism. Good news! There are designs that are customized to your eye. It can take more visits to obtain the right lens, but it’s worth the extra time!
A growth of pink, fleshy tissue on the conjunctiva (the white clear tissue around the iris) is called a pterygium. It can look scary, but it usually isn’t cancerous. The growth might spread slowly during your life or stop after a certain point. In extreme cases, it can cover your pupil and cause vision problems. It can cause annoying symptoms. You might feel like you having something in your eye. When it gets red and irritated, it can be treated with anti-inflammatory eye drops. Surgical treatment is uncomfortable, but effective. Though sometimes, it can grow back.
Not necessarily! An eye freckle is called a nevus. It is a common, colored growth, similar to a freckle on your skin. You can have a nevus in the front of your eye, around the iris, or under the retina at the back of the eye. A nevus under the retina is called a choroidal nevus. An eye nevus is usually harmless. However, it needs to be monitored because, like a skin freckle, it could possibly develop into cancer of the eye.
With more public appearances, I would like to look my best and get rid of my glasses! I found out that I’m an ideal candidate for Lasik. I was worried about my corneal thickness, but everything was OK! I am seriously considering Lasik, as it would really improve both my vision and my quality of life. Stay tuned!
Dry macular degeneration is a common eye disorder among people over 65. It causes blurred vision, due to disruption of the pigmented layers in your macula. The macula is the part of the retina responsible for your central vision.
Prevention and early detection may delay vision loss due to dry macular degeneration. I recommend getting enough Lutein into your daily diet. I take Macuhealth every day, since I have a family history of macular degeneration.
MacuHealth® with LMZ3 is a nutritional supplement that helps enhance vision by restoring important pigments found in the eye. Within the macula, there is an important and naturally occurring protective substance known as macular pigment, which is made of three nutrients: lutein, zeaxanthin and meso-zeaxanthin. MacuHealth is the only supplement containing all three of these crucial carotenoids in the recommended dosage.
White blood cells can penetrate into the corneal tissue as part of the body’s inflammatory response to the presence of bacterial toxins.
A corneal ulcer is an epithelial defect with underlying inflammation and involves much more pain, redness, and vision loss. An ulcer is more serious and requires immediate, aggressive treatment with antibiotics taken every hour.
Infiltrates usually resolve with anti-inflammatory drops. Contact lens wear must be discontinued!
Corneal pannus is the growth of blood vessels onto the cornea. A common cause of corneal pannus is contact lens wear, particularly if the contacts aren’t fitted properly. In that case the contacts should be refitted, or perhaps discontinued. Sometimes pannus is a result of past infection such as herpes simplex. Sometimes corneal pannus is not easily treated and cannot be reversed.
A bandage contact lens and antibiotic drops taken every 1-2 hours work like a charm! Healing usually takes 1-2 days.
Scleral lenses provide excellent vision and comfort for those with highly irregular corneas, such as keratoconus. However, a poorly fit scleral lens can lead to conjunctival blanching and patient discomfort.
A pterygium is an elevated, wedged-shaped bump on the whites of the eye. It can grow onto the cornea. Though it’s commonly called “surfer’s eye,” you definitely don’t have to be a surfer to get a pterygium. But being at a higher elevation with more UV exposure increases your risk for getting it. Most pterygium are benign, but they can cause discomfort and blurry vision.
Posterior Vitreous Detachment (PVD) is common and occurs when the vitreous gel that fills the eye separates from the retina. Symptoms include floaters and flashes in your vision. In this photo, the patient had cataract surgery, so the floater is more visible.
Online shopping has truly revolutionized the way we purchase things. Indeed, many of us prefer online shopping to in-store shopping. Now, coming to a theater near you, the first online eye exam that gives you a prescription! This is where the lure of “cheap and convenient” is a disaster waiting to happen.
Recently, I had a patient come in for an eye examination with no vision changes or complaints. I dilated the eyes for a full view of the retina and found retinal holes with underlying fluid. Prompt treatment by a retinal surgeon prevented severe vision loss. Many eye diseases have no symptoms, but early intervention can prevent permanent eye damage and blindness. Contact lenses can compromise the health of your eyes and should not be worn without yearly evaluation.
Many conditions, such as hypertension, diabetes, and autoimmune diseases, first show up in the eye. Evaluation of eye health takes time and care via physical examination. Online questionnaires, Skype interactions, automated instruments, and Iphone apps alone are inadequate.
For quality eyewear, you need an experienced optician who can take several measurements, customize glasses to your visual needs and lifestyle, verify their accuracy, and troubleshoot any problems. Vistakon, the maker of Oasys contact lenses, just announced their “unilateral pricing agreement” where you will receive the same pricing through all online companies, 1-800-contacts, and at our office. At Los Alamos Family Eyecare, our goal is to give you the best vision possible and take care of your eye health. We don’t want you to “go online” when it comes to your eyes!
Epithelial ingrowth is the presence of corneal epithelium in an area where it does not belong. After LASIK, epithelial ingrowth can occur in the interface between the flap and the stromal bed of the patient’s cornea. If the ingrowth is peripheral and not vision threatening, it can just be monitored.
I use my optical coherence tomographer (OCT) for evaluating complex contact lenses, such as sclerals. It is important that there is enough space between the cornea and the contact lens.
|•||Evaluating pachymetry and corneal edema|
|•||Measuring soft and GP lens thickness—centrally and peripherally|
|•||Examining lens edges for flaws and causes of discomfort|
|•||Measuring posterior tear film thickness in scleral lenses|
|•||Assessing points of lens bearing to determine the need for design modification|
A scleral lens that is fit too tightly in the periphery can result in vascular blanching. To remedy this situation, flatten the midperipheral curves to loosen the fit.
This is a common complication of cataract surgery, which usually resolves after 1 week. Those who have more advanced cataracts pre-existing corneal disease are more likely to have corneal edema. The primary treatment is typically steroid drops and hyperosmotic agents such as Muro 128 (a hypertonic saline agent) which pulls the edema fluid out of the cornea. In most cases, the visual prognosis is good.
Did you scratch your cornea? The cornea is one of the most sensitive parts of your body, so even a very small corneal abrasion can be uncomfortable. In addition to pain and feeling that something is in your eye, other symptoms include redness, tearing, light sensitivity, headache, blurry or decreased vision, eye twitching, a dull ache and rarely, nausea.
A bandage contact lens and antibiotics are very effective in healing corneal scratches.
The lacrimal caruncle is the small nodule at the inner corner of the eye. It is made of skin covering sebaceous and sweat glands. Sometimes it can get inflamed and swollen. Artificial tears and steroids usually resolve the problem.
Did you know that bleeding underneath your retina can cause devastating vision loss? Choroidal neovascular membranes are new blood vessels that grow beneath the retina in an area called the choroid. These membranes are associated with many serious eye diseases, most commonly wet age-related macular degeneration. CNVM are also found in patients with histoplasmosis, eye injury, and myopic macular degeneration.
Giant papillary conjunctivitis is a common complication of contact lens wear. This condition requires anti-inflammatory and/or anti-histamine eye drops. Contact lens wear should be temporarily discontinued. Daily disposable contact lenses are recommended.
The inner eyelids usually return to normal appearance following the resolution of giant papillary conjunctivitis. However, sometimes, there can be permanent, small, white, capped scars of the giant papillary bumps.

You are what you eat — we’ve heard it since we were children. Not surprisingly, what we eat today is simply not as nutritious as a generation or two ago. Industrial farming techniques have caused many of our foods, especially fruits and vegetables, to be deficient in nutrients.1 Simply put, our diet lacks the necessary nutrients for our bodies to fight the constant barrage of inflammation and stress that we encounter on a daily basis.
According to the Glaucoma Research Foundation, an estimated 2.2 million individuals in the United States have glaucoma. More than half of those who have glaucoma are unaware because there are NO SYMPTOMS, especially in the early stages. Studies show that the risk of blindness related to glaucoma 20 years after diagnosis has decreased by 50% due to early intervention and consistent treatment. Annual eye examinations with advanced technology, we can treat glaucoma early and prevent complications such as vision impairment, loss of peripheral vision, and blindness.
