Based in Tucson, Arizona, Dr. Cameron Javid leads Retina Associates and offers a comprehensive range of ophthalmologic care. The Retina Associates team also has extensive experience in treating age-related macular degeneration (AMD) among its patients.
This common condition involves damage or breakdown in the macula, which lies at the back of the retina and enables fine details to be recognized. Approaches that Dr. Cameron Javid offers patients experiencing blind spots include anti- vegf injections, photodynamic therapy, which employs the intravenous administration of a light-activated drug. Also, several national clinical trials using new medications are available.
In PDT, the IV medicine travels from the arm to the center of the macula, where it accumulates in the blood vessels that are growing abnormally and leaking fluid. At this point, the drug is activated in the macular area through use of a specialized low-intensity laser light (cold laser) that seals these abnormal blood vessels while maintaining the integrity of the normal blood vessels. The result is that the retina is not damaged, while abnormal leakage is inhibited and vision is stabilized and/or improved.
Led by Dr. Cameron Javid, Retina Associates is a Tucson, Arizona-based ophthalmology practice that treats medical issues surrounding the retina and vitreous parts of the eye. One of the most common problems the professionals at Retina Associates deal with is retinal tears.
The retina is the layer of tissue on the back of the human eye that receives light brought in and focused by the lens. It transforms the light into neural signals and forwards them to the brain, thus enabling visual recognition. When a person experiences a retinal tear, in which the retina pulls away within the eyeball, that individual may experience an increased number of floaters and/or flashes within his or her line of vision. These floaters look similar to specks or tiny cobwebs that are most apparent when the eye is focused upon a solid, light-colored surface.
A retinal tear can sometimes progress to a retinal detachment, which is a medical emergency that can lead to significant vision loss or even blindness. An Individual’s risk of developing retinal detachment increases if he or she is over the age of 50, has nearsighted vision, history of eye surgery, trauma, thinning of the retina or has a family history of the condition.
Tucson, Arizona-based Retina Associates provides diagnosis and treatment for a variety of retina and vitreous disorders through a team of experienced vitreo-retinal surgeons that include Dr. Cameron Javid. Disorders treated by Retina Associates include retinal detachment, a serious eye condition that can lead to a permanent loss of vision if left untreated.
Retinal detachment occurs when the retina separates from the surrounding tissue, which can result from age, pre existing conditions causing thinning of the retina, injury, advanced diabetes, inflammatory eye disorders, or the shrinkage or contraction of the vitreous, a gel-like material inside the eye. Retinal detachment may also occur when vitreous collects underneath the retina through tears in the retinal tissue. Symptoms of the condition cause no pain but manifest instead in the form of darkening of the peripheral or central vision, flashes of light, and the appearance of debris or floaters in one’s vision. Permanent blindness may occur due to a prolonged lack of oxygen as the disorder restricts the flow of oxygen to retina cells.
Due to the risk of permanent blindness, ophthalmologists advise those with retinal detachment to seek immediate medical help. Patients require surgery in nearly every case, although the type of surgery depends upon the severity of the individual case. Vitreo-retinal surgeons can treat retinal tears that have yet to progress into full detachment with outpatient procedures; such as laser, however, full detachments may require more intensive surgical options. Treatment success varies on a case-by-case basis and in part depends upon damage done to the central area of the retina and the extent of oxygen loss to the retina cells. Vision can take months to improve even in the case of successful operations.
