Common Eye Conditions

Dr. Roberts performs a comprehensive suite of ophthalmic surgery for many different eye diseases and conditions. For other, non-surgical conditions, a continually updated array of diagnostic tools are utilized to provide reliable and accurate measurements of all metrics of ophthalmic health and function. In this way, only the best information informs the diagnostic and decision-making process.

Dr. Roberts performs on-call services for the department of Ophthalmology of the QE II Hospital of Grande Prairie in a regular rotation with his colleagues, which provides coverage for the western half of Alberta Health Services North Zone, as well as the region of northeastern British Columbia. In this way, urgent and emergent eye conditions and trauma are also addressed at night and on weekends, providing a safety net to patients outside of regular office hours.

While the majority of conditions and diseases of the eye and associated structures can be managed locally, some complex conditions may require sub-specialty care and referral for co-management with colleagues in Edmonton or Calgary.

 

Age-Related Macular Degeneration

Age-related macular degeneration (ARMD) is a chronic and progressive disease that causes a blurring of the central vision of one or both eyes. In this way, ARMD affects a person’s ability to focus their sharpest vision for fine visual tasks, such as driving, reading, watching television and for recognizing faces. The rate of change (and progression) of the condition is different for different people, and also depends on the type of macular degeneration.

Cataracts

A cataract is a cloudiness or an opacification of the natural, crystalline lens of the eye. While most cataracts occur as a result of aging, other causes of cataracts can be due to in-born errors of eye development, physical trauma or due to the ingestion of certain medications. Cataracts impair vision by interfering with the normal transmission and focusing of light through the pupil and onto the surface of the retina.

Diabetic Retinopathy

Diabetic Retinopathy is the name given to the collection of problems of the retina (nerve layer) of the eye which are directly caused by damage from diabetes. This condition can affect patients with any form of diabetes mellitus. Over time, chronic damage of the small blood vessels of the retina can cause diabetic retinopathy to form, which is of two main types.

Dry Eye

A constellation of symptoms (and some signs) which are related to office procedures such as Meibomian gland probing, Blephex and Lipiflow. Some of the many symptoms which are caused by dry eye disease include: burning, stinging, itching, tearing, light sensitivity, eye pain, sandy/gritty feeling, heavy eyelid feeling, discharge, mattering or caking of the eyelashes/eyelids, redness, and blurry vision (especially when concentrating on a computer or cell phone, when reading or when driving for sustained periods of time).

Eyelid Malposition

Ectropion and entropion are two conditions whereby the eyelid (most commonly the lower eyelid) is not in its normal anatomic position in its usual relationship with the eyeball. Some risk factors for the development of either condition include age, smoking, eyelid rubbing, previous eyelid surgery and trauma.

Glaucoma

Glaucoma is a disease of the optic nerve(s), the nerve which transmits the visual information captured by the eye for transport to the brain, so that a person can see. In this condition, the nerve(s) become irreversibly damaged through nerve fibre loss over time, and without appropriate treatment it is relentlessly progressive, which leads to common patterns of loss of the field of vision (and ultimately, central vision).
