Regular comprehensive eye exams include checking your glasses prescription and assessing the ocular health of your eye with a dilated exam. Your Optometrist is able to use the latest imaging technology to better assess your eye health, allowing them to see different aspects of the eye and to document the current ocular condition at different points in time. All imaging are non-invasive and allows your eye doctor to view your ocular health in more depth. Such technology includes topography, anterior segment photos, and posterior segment photos.

Topography is an imaging technique that measures the curvature of the cornea (clear part of the eye). This technique displays a three-dimensional map showing whether the cornea has an irregular shape. A smooth corneal curvature is necessary to maintain clear vision, if there are any distortions to this smooth surface, decreased vision could occur. Diseases that can be diagnosed or monitored with topography include keratoconus, pellucid marginal degeneration, irregular astigmatism, corneal deformities, corneal scars, and ocular surface disease like dry eye.

Anterior Segment Photos are images of the front surface of the eye. This includes the eyelids, cornea, and conjunctiva (white part of eye). This imaging is important to monitor various ocular conditions and ensure that no growth has occurred. Such conditions could be benign such as nevus on the eyelid (pigmented lesion) or melanosis (hyperpigmentation). Additionally, anterior segment photos are useful for monitoring more severe conditions such as corneal ulcers to help ensure the lesion is healing with each visit.

Posterior Segment Photos are images of the retina (back portion of the eye). The retina is another part of the eye essential for vision. This portion of the eye is a common location for many manifestations of diseases. Posterior segment photos can help monitor disease processes and help identify if progression has occurred. Such diseases include diabetic retinopathy, age related macular degeneration, and maculopathy caused by systemic medications.

Do you really need your prescription printed?

This Earth Day (April 22nd) we really want to set mind on something important and meaningful: little actions that don’t cost anything and have a big impact. 

Reducing paper consumption is a great way to help the environment!!! According to the Paperless Project, on average, a person in the United States uses more than 700 pounds of paper every year. Approximately 68 million trees each year are used to produce paper and paper products, which represents one of the biggest components of solid waste in the U.S.

Here at Vision Unlimited, we have been pioneers in the reduction of paper in our Optometry Practices. Since 2002, Doctor Mario Carcamo started developing an Optometric Practice Management Software that allows us to keep your information in a safe electronic format and eliminate paper files. Thanks to his vision and effort, our transition to the mandatory meaningful use of Electronic Medical Record, has been smooth and completed successfully, since 2014.

Today we have the ability to access your records from any of our location, share your medical information with your Primary Doctor and Specialist, send your Therapeutic Prescription to any Pharmacy in the U.S., and Email or EFax your Glasses and/or Contact Lenses Prescription, Orders and Invoices at any time.  All this without using a single sheet of paper.

We encourage you to take advantage of these services and help us save a tree one paper at a time…

Wearing sunglasses is more than just a fashion statement

Sun wear is an important way to protect your eye. Over time exposure to UV light can increase aging changes in your eyes. The delicate tissue of our eyes absorbs the energy from UV light causing changes to the tissues structure and therefore accelerating many eye conditions. Some of the changes to our eyes include: Cataracts, Pingueculas, and Age related macular degeneration.

Cataracts are a normal aging change in the crystalline lens of the eye. The lens functions to help focus incoming light onto the retina, allowing us to have clear vision. A cataract refers to the process of this lens becoming cloudy over time as the structure rearranges itself.

Pingueculas are yellow elevated area on the conjunctiva (the white part) of the eye. They can occur on either the side of the iris (colored part) of the eye and occur most commonly in people with higher exposure to sunlight.

Age Related Macular Degeneration is a condition that affects the retina. The macula provides sharp central vision. The earliest presence of the disease is characterized by drusen. Drusen are yellow deposits under the retina made up of fatty proteins.

All of these conditions can be diagnosed and monitored by your Optometrist during a comprehensive eye exam. Through yearly dilated exams your eye doctor will be able to visually assess your eyes and use special equipment such as anterior and posterior segment photos, and OCT to check for progression. You can help protect your own eyes by wearing sunglasses whenever outdoors, wide brimmed hats, or even transition lenses (glasses that turn from clear indoors to darker shade when exposed to UV light outside).
