Eye Diseases

A quick look at some of the most common eye diseases diagnosed and often treated at Day Creek Optometry in Rancho Cucamonga

“Eye diseases” is a blanket term that refers to a host of diseases relating to the function of the eye. Below we describe some of the more common types of eye diseases and how they are generally treated. For more in-depth information, please speak with your eye care provider at Day Creek Optometry.

Conjunctivitis (Pink Eye)

Conjunctivitis, also known as pink eye, is an infection or inflammation of the conjunctiva – the thin, protective membrane that covers the surface of the eyeball and inner surface of the eyelids. Caused by bacteria, viruses, allergens and other irritants like smoke and dust, pink eye is highly contagious and is usually accompanied by redness in the white of the eye and increased tearing and/or discharge.

While many minor cases improve within two weeks, some can develop into serious corneal inflammation and threaten sight. If you suspect conjunctivitis, visit your eye care provider at Day Creek Optometry for an examination and treatment.

Diabetic Eye Disease

Diabetic eye disease is a general term for a group of eye problems that can result from having type 1 or type 2 diabetes, including diabetic retinopathy, cataracts and glaucoma.

Often there are no symptoms in the early stages of diabetic eye disease, so it is important that you don’t wait for symptoms to appear before having a comprehensive eye exam. Early detection and treatment of diabetic eye disease will dramatically reduce your chances of sustaining permanent vision loss.


Often called “the silent thief of sight,” glaucoma is an increase in the intraocular pressure of the eyes, which causes damage to the optic nerve with no signs or symptoms in the early stages of the disease. If left untreated, glaucoma can lead to a decrease in peripheral vision and eventually blindness.

While there is no cure for glaucoma, there are medications and surgery available that can help halt further vision loss. Early detection and regular eye exams are vital to slowing the progress of the disease.

We are committed to providing a complete and comprehensive eye examination. From early detection of potential eye diseases such as glaucoma, macular degeneration, and cataracts, to specific diagnostic testing, we have the state-of-the-art equipment to offer a full scope of preventative and diagnostic services.

We now offer the newest technology in eye pressure testing !!!


Yes, you read that right. Our office now uses the:

ICARE Tonometer

The ICare tonometer uses a very light touch to make contact with the cornea. So quick it does not even trigger a corneal reflex, which means you cannot even feel it. Most of our patients say that it feels like tickling on their eyelashes. The ICare tonometer is still just a screening method so if further evaluation is needed drops may need to instilled and a standard care method of measuring pressure may have to still be done. The ICare tonometer is just another way we make things comfortable for our patients. Want more information, give us a call. We are more than happy to answer your questions. Better yet come in and experience the ICare for yourself!! We look forward to seeing you.

Macular Degeneration

Macular degeneration is a chronic, progressive disease that gradually destroys sharp central vision due to a deterioration of the macula, a tiny spot in the central portion of your retina comprised of millions of light-sensing cells. Because it is so commonly associated with aging, it is also known as age-related macular degeneration (AMD). There are two forms of AMD called “dry,” most common and with no known treatment, and “wet,” less common and treated with laser procedures. Genetic testing is now available to help identify those most likely to develop “wet” macular degeneration.

In most cases, reversing damage caused by AMD is not possible, but supplements, protection from sunlight, eating a balanced diet and quitting smoking can reduce the risk and progression of macular degeneration. For suggestions, speak with your eye care provider at Day Creek Optometry.

Day Creek Optometry has the experience and equipment necessary to diagnose and often treat the eye diseases detailed above, as well as many other eye diseases, at our office in Rancho Cucamonga.
