Tucson, Arizona-based Retina Associates focuses on the treatment of retina and vitreous disorders through a team of licensed ophthalmologists with extensive diagnostic and surgical experience. Retina Associates ophthalmologist and vitreoretinal specialist Dr. Cameron Javid belongs to the American Society of Retina Specialists, and will participate in the Annual Ophthalmology Meeting 2017 in November.
A global assembly of academicians, researchers, medical providers, and other professionals in ophthalmology, the Annual Ophthalmology Meeting serves as a platform for the latest knowledge and resources in ocular science. The event encourages researchers to unite in efforts against blindness and promotes research across the fields of ophthalmology, and vision science. Attendees also have the opportunity to network and connect with leading professionals in the industry.
Educational sessions and tracks carry the theme “the science of Eye” and feature an exceptional accumulation of ophthalmology and vision science professionals. A fusion of workshop and symposium events, the meeting covers a wide variety of topics, ranging from ophthalmic pathology and to pediatric ophthalmology and nutritional ophthalmology. Presenters will also review conditions such as retinal detachment, eye cancer, and ocular migraine.
Led by Dr. Cameron Javid, Retina Associates serves the needs of Tucson, Arizona. Among the complex conditions that Dr. Javid and his team at Retina Associates handle are choroidal melanoma.
Melanoma occurs in the uvea, which encompasses a number of regions in the eye, including the choroid and the iris. The most common type of eye cancer, melanoma typically affects people from middle age on and has symptoms such as flashing lights, blurred vision, and floaters. As it carries with it the risk of metastasis to the liver, lung and rarely skin, patients are recommended to undergo lifelong systemic monitoring.
Common melanoma treatments include Plaque radiation treatment, proton beam radiation, enucleation or TTT as an adjunctive treatment. In cases where metastasis has occurred, regimens of chemotherapy and immunotherapy may be recommended in clinical trials. Dr Cameron Javid is actively involved in over a dozen clinical trials. Dr Javid has current trials available for metastasis from eye melanoma.
At Retina Associates in Tucson, Arizona, Cameron Javid MD, FACS provides skilled and experienced care to patients with ocular cancers, among other retinal disorders. Retina Associates stands out as one of only a few practices in the United States chosen for participation in the highly regarded Collaborative Ocular Melanoma Study. Current cancer studies include the Collaborative Ocular Oncology Group Uveal Melanoma Validation Study Number 2 (COOG2).
For patients diagnosed with ocular melanoma, or melanoma of the eye, treatment depends on the tumor's size and stage of development. Particularly small melanomas may require no more than a watch-and-wait approach, though larger or symptomatic tumors call for active intervention.
This intervention may include some form of radiation, the most common of which being brachytherapy. Also known as plaque therapy, this treatment requires the surgical placement of a small device containing radioactive seeds, which the treatment team places on the outside of the eye. Over the course of a few days, the radiation treats the tumor effectively.
Other forms of radiation therapy for ocular melanoma include proton beam radiotherapy. This option involves targeted delivery of radiation to the tumor itself.
Patients with large or recurring tumors may need to undergo surgery, either after or instead of radiation treatment. Procedures range from complete removal of the eye to repeat radiation if additional growth of tumor is noted. The choice depending primarily on the tumor's size and location. Sometimes laser treatment, called TTT laser after radiation treatment may be necessary to help prevent recurrence.
At Retina Associates in Tucson, Arizona, Dr. Cameron Javid and his colleagues treat such conditions as macular degeneration, diabetic retinopathy, and macular pucker. The staff at Retina Associates approach these cases with an in-depth knowledge of the retina, its anatomy, and its function.
At the back of the human eye, the retina serves the essential function of receiving visual information from the environment and transferring it to the brain. The external layer of the retina consists of photoreceptive cells, which collect light and pass it toward the rear of the retina, where structures known as rods and cones start communication with the brain.
Rods are primarily responsible for low-light photoreception, while cones support color and daytime vision. The densest concentration of cones is present in the fovea, defined as the 3 millimeter area located at the very center of the macula. In this region, which is the thinnest of the retina, light strikes directly and provides a high level of visual precision.
The rods and cones serve to transmit light through a series of synapses, each of which is oriented either vertically or horizontally to the retinal surface. This process terminates in the axions of the ganglion cells, which converge at an area known as the optic disc. Here, the ganglion cell axions carry signals to the lateral geniculate nucleus of the brain stem, where the brain interprets the resultant signal into something recognizable as an image.
Retina Associates is a Tucson, Arizona, practice guided by Dr. Cameron Javid that offers a full range of care for eye conditions from diabetic retinopathy to floaters and everything in between. For example, Dr. Cameron Javid and his Tucson, Arizona, team at Retina Associates provide experienced care for macular pucker, which is associated with blurry central vision.
The condition occurs when the macula, which is situated flat along the back of the eye, creases, bulges, or forms wrinkles. This has to do with the aging process and the tendency of the gel-like vitreous substance in the center of the eye to diminish and move away from the retina.
Detecting macular pucker involves the ophthalmologist performing a retina examination, often through the use of photographic methods such as optical coherence tomography or fluorescein angiography. If mild symptoms are present, the solution may be as simple as updating the eyeglass prescription. In more severe cases, the surgical procedure vitrectomy may be recommended.
At Retina Associates in Tucson, Arizona, Dr. Cameron Javid and his colleagues provide specialized ophthalmological care for a variety of conditions. The team at Retina Associates draws on a comprehensive, in-depth knowledge of the retina and the vitreous to support and correct patients’ vision.
Located at the back of the eye, the retina collects focused light from the lens and transforms it into neurological signals. It is a thin layer of tissue that consists of photoreceptor cells known as rods and cones, as well as supplemental bipolar, ganglion, horizontal, and amacrine cells.
The photoreceptor cells lie closest to the interior of the eye. These cells include an outer section of photopigment, which collects light signals and initiates the process of signal transformation.
Cones, concentrated at the center of the retina, generate sharply detailed signals rich in color. The central area of the retina, or fovea, includes only these cells. Rods, which provide less color information and resolution but are more light sensitive, appear in the retina as it extends outward. Rods provide vision in low light and are present all the way to the edge of the retina itself.
Details of light perception also result from the interactions between photoreceptors, bipolar cells, and horizontal cells. Because these cells are located laterally across the retina, they are able to transmit varying types of information simultaneously and generate a complete visual picture.
Retina Associates, located in Tucson, Arizona, aims to provide quality optometry services to its patients to help safeguard their vision and improve quality of life. As well as performing eye surgeries, Dr. Cameron Javid and other members of the staff at Retina Associates advise patients on proper follow-up care, which may include facedown recovery after a retinal procedure.
In cases when a person has retinal damage, such as in the instance of a macular hole or detached retina, a doctor might perform a type of surgery that involves taking out the fluid in the back of the eye. Afterward, the doctor will insert gas into the eye as a replacement for the fluid, causing a bubble to form. This bubble is only temporary; natural eye fluid will eventually take its place. However, during recovery, the bubble needs to stay in the correct place on the eye, requiring the patient to maintain certain head and eye positions at all times.
The patient will need to keep the head down for up to a few weeks following the procedure as directed by the doctor, even while walking. The same goes for activities such as eating, reclining in bed, and standing. Having a family member nearby to help with regular tasks and act as a guide can be a big help during this time, and can prevent injuries associated with maintaining the proper head position while walking.
To make this period more comfortable, one might consider purchasing or renting special equipment designed to promote proper healing, such as face-down pillows or chairs, as well as face cradles that can go on a table surface. A doctor can offer additional tips and guidelines for proper retinal surgery recovery.
In Tucson, Arizona, Dr. Cameron Javid and his fellow physicians at Retina Associates welcome numerous patients with retinal tears and detachments. The team at Retina Associates draws on a comprehensive knowledge of how such events occur.
Retinal detachments affect the layer of tissue that transforms light signals into messages that the optic nerve can carry to the brain. In a healthy eye, this retinal tissue lies against the back curve of the eyeball behind the gel-like vitreous, which serves as a carrier for light as it enters the eye. Sometimes, however, the vitreous exerts force on the retina and causes it to pull away from the retina.
In the most common type of retinal detachment, known as rhegmatogenous detachment, separation occurs as fluid slips under the retinal cells. This may also occur in cases of exudative detachment, which involves fluid leakage but no break of the retinal itself. Tractional detachments, common in diabetics, can develop scar tissue on the retina causing retinal elevation and visual loss. Fortunately all types of retinal detachments are treatable.
Based in Tucson, Arizona, Retina Associates is led by Dr. Cameron Javid and provides a full range of care for conditions involving the retina, or back of the eye, from choroidal melanoma, diabetic retinopathy, macular degeneration etc... Dr. Cameron Javid and his Tucson, Arizona, team at Retina Associates also perform retinal care for all retinal conditions.
Recognizable as small clouds or specks that move across the field of vision, floaters are particularly visible when gazing at a blank background such as the sky or a wall. The objects are not in front of the eye, as they appear, but within it. They are composed of tiny cell and gel clumps suspended within the eye’s gel-like vitreous fluid. Common shapes include circles, lines, dots, and clouds.
The cause of floaters is posterior vitreous detachment, which involves the gel-like substance pulling away from the back of the eye. This can occur as people age, and the sudden appearance of a floater is a concern and needs to be seen promptly as it can result in a retinal tear or detachment. This is a sign that one should quickly visit an ophthalmologist or retina specialist!
