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.
If you have blepharitis, which results in sore, red eyelids, with crusty debris, Demodex mite infestation could be the cause! The incidence of Demodex infestation increases with age, occurring in 84 percent of the population at age 60 and in 100 percent of the population older than 70 years of age. One way to preventContinue reading “Crud on the Eyelids!”
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 pterygiumContinue reading “A Surfer’s Eye”
One of the causes of sudden blurry and distorted vision is a macular hole. The macula, is a very small spot in the retina. Prompt referral to a retinal specialist is necessary for treatment.
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. Symptoms usually subside over several weeks. Rarely, a PVD can develop into somethingContinue reading “A Huge Floater!”

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. TABLE 1 Applications for Anterior Segment OCT in a Specialty Contact Lens Practice • Evaluating pachymetry and corneal edema • Measuring soft and GP lensContinue reading “OCT in Scleral Lens Fitting”
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.
After lasik, stria can occur. Visual acuity determines their severity and the need for surgical revision.
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 outContinue reading “Corneal Edema After Cataract Surgery”
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.

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 myopicContinue reading “Neovascular Membrane”
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,Continue reading “When Contacts Cause Bumps in the Eye”
by Damon Dierker, OD, FAAO Can We Eat Our Way to a Healthy Macula? The answer is YES! 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 ofContinue reading “Preserving Macular Health”
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 byContinue reading “Glaucoma: the Importance of Early Intervention”
Meibomian refers to a particular type of gland in the eyelids. There are about 25 to 40 meibomian glands in the upper eyelid and 20 to 30 in the lower eyelid. The function of these glands is to secrete oils, which help keep the tears from evaporating too quickly. Meibomian gland dysfunction is blockage orContinue reading “Meibomianitis”
The retina is nourished by blood flow, which provides nutrients and oxygen that nerve cells need. When there is a blockage in the veins into the retina, retinal vein occlusion may occur. Central retinal vein occlusion (CRVO) is a blockage of the main vein in the retina. Blockage of the small veins in the retinaContinue reading “Central Retinal Vein Occlsion”
Corneal pannus is the growth of fine blood vessels onto the clear corneal surface. The treatment depends on the cause. For instance, a common cause of corneal pannus is a poorly fit contact lens. Also, pannus can occur if the contact lens does not allow enough oxygen to the eye. Contact lens may need toContinue reading “Corneal Pannus”
Episcleritis is a self-limited inflammation that does not cause lasting damage. Most patients with episcleritis may not require any treatment. Either Prednisolone Acetate 1.0% or Fluorometholone .1% 1 drop 3x/day can be prescribed. Cold compresses can also help relieve the discomfort.

Asteroid hyalosis is a common condition in which calcium-lipid complexes are suspended throughout the collagen fibrils of the vitreous.
Chemical alkali burns of the cornea, are the most severe and painful. Treatment requires medical intervention, sometimes surgery, acutely and in the long term, for maximal visual rehabilitation. Common goals of management include: (1) removing the offending agent, (2) promoting ocular surface healing, (3) eliminating inflammation, (4) preventing infection, and (5) controlling intraocular pressure. ImmediateContinue reading “Bad Eye Burn”
Small, yellowish deposits known as drusen, can have discrete or indistinct margins. Macular degeneration can be classified according to the number and size of drusen, amount of geographic atrophy, and pigmentary changes. This patient has dry macular degeneration, which is being carefully monitored with photos, as well as daily Lutein supplements.
When you over wear your contact lenses, blood vessels begin to grow onto your cornea. This causes redness and corneal edema.
1 week after cataract surgery. The first week is always the most uncomfortable. There is injection and inflammation. You must stay on your anti-inflammatory and anti-biotic drops, 4x/day without fail!
Symptoms include foreign body sensation, photophobia, tearing, burning, and pain. Treatment includes bandage contact lens, cyclosporine, and ocular steroids.
Sometimes the intraocular lens implant, in cataract surgery, can become opacified.
If you do not properly disinfect and clean your contact lenses or over wear them, you can develop bacterial keratitis. This is a serious condition that can cause permanent vision loss and damage to your eye. It must be treated aggressively with antibiotics.
