With advances in technology and better understanding of the various disease processes, retina or vitreo retina has become an important sub-specialty of ophthalmology. It deals with the diseases affecting the innermost sensitive layer of the eye called the 'retina'. Retina is like a film at the back of the camera. The image of the object that a person sees is formed on the retina, from where it is transmitted to the brain. Any disease affecting the retina will directly affect a person's vision.
What is Retina?
Retina is a thin sensitive layer at the back of eye. It is like the film at the back of the camera. The image of an object that a person sees is formed on the retina, from where it is transmitted to the brain.
The common symptoms of retinal problems are:
- Blurring or decrease/loss of vision
- Distortion of images
- Flashes of light
- Floaters in front of eye (tiny spots, spectrums, flecks and "cobwebs" that drift aimlessly around your field of vision)
- Difficulty in dim light or bright light
- Redness and pain in the eyes
Many retinal problems, however, may not show any symptoms in the early stages-a reason why patients with higher risk of retinal problems like patients with diabetes, myopia (near sight), family history of eye problems, etc should undergo a retinal examination regularly before the onset of the symptoms. In order to specifically deal with the various retinal disorders, Manipal Eye Care has started a dedicated Retina Center in the Department of Ophthalmology.
The Retina Center is fully geared and equipped to handle all Vitreo Retina disorders.
- Diabetic Retinopathy-Involvement of the retina due to diabetes is called Diabetic Retinopathy. If left untreated, it can lead to loss of vision
- Age related Macular Degeneration- AMD is a common eye condition among people age 50 and older. It is a leading cause of vision loss in older adults. It gradually destroys the macula, the part of the eye that provides sharp, central vision needed for seeing objects clearly.
- Central and Branch Retinal Vein Occlusions (CRVO & BRVO) - Central retinal vein occlusion is closure of the final retinal vein (located at the optic nerve) which collects all of the blood after it passes through the capillaries. Branch retinal vein occlusion is essentially a blockage of the portion of the circulation that drains the retina of blood.
- Retinal Detachment - A retinal detachment is a separation of the retina from its attachments to the underlying tissue within the eye.
- Retinopathy of Prematurity (ROP) - Premature babies, with abnormally developed blood vessels in the retina.
- Myopia related Retinal Problems-Myopia is near sight.
- Uveitis and Inflammatory Eye Diseases-Uveitis is swelling and irritation of the uvea, the middle layer of the eye. The uvea provides most of the blood supply to the retina.
- Injuries related Eye Problems
- Hypertensive Retinopathy - is damage to the retina and retinal circulation due to high blood pressure (i.e. hypertension)
- Central Serous Chorioretinopathy - is a disease in which a serious detachment of the neurosensory retina occurs over an area of leakage
- Eales' Disease - a condition marked by recurrent haemorrhages into the retina and vitreous, affecting mainly males in the second and third decades of life.
- Hereditary Retinal Disorders: The causes of these diseases are inherent or genetic.
Facilities available at Retina Center:
The Retina Center is fully equipped with the most modern equipments and offers the best of technology to tackle the most complex retinal diseases. The following facilities are available at the Retina Center:
- Computerized Digital Imaging System: This is useful for performing Fundus Photography, Fluorescein Angiography, ICG Angiography and Auto fluorescence Imaging.
- OCT (Optical Coherence Tomography) gives us high resolution images of the retina to understand and treat the retinal disease process better.
- Alcon Ultrascan B-Scan Ultrasound Imaging System: This is a useful investigative tool to assess the status of the retina and the other eye structures.
- Zeiss VISULAS 532 Laser: For performing laser treatment in different retinal diseases. The system includes the slit lamp delivery and the indirect laser delivery system.
- PDT Laser (Photodynamic Therapy) is used to treat specific age related retinal problems.
- IRIS Medical 810 Laser System: Used for micropulse laser delivery and for transpupullary laser delivery for treatment of specific retinal conditions.
- Humphrey Visual Field Analyzer: Useful for monitoring the visual fields in patients with different retinal and optic nerve disorders.
- Fundus Camera for fundus photography, Auto auto fluorescence image, FFA and ICG
The ultra modern operating room facility at the Retina Center is well equipped to perform regular retinal surgeries and also the small gauge 23, 25 Vitrectomy (is the surgical remove of the vitreous gel from the middle of the eyes). The surgical facility at the
