Common Retinal Issues
The most common type of retinal disorders are Macular degeneration, Diabetic Retinopathy, Retinal Scars, etc.
At RK Eye Centre, we have embraced the rapid strides in technology especially in the field of diagnostic imaging of the retina and vitreo retinal surgery. We have the capacity to take pictures of the back of the eyes and even take optical slices of the retina without any direct contact. Even if the retina cannot be visualised due to various reasons like corneal scars, or cataracts, we have the capability of getting high resolution scanned images of the entire eye
1. Fundus Photography – Kowa, Japan
Permits us to procure color photographs and red free images of the back of the eye.
2. Fluorescein Angiography (FFA) – Kowa, Japan
This diagnostic procedure enables us to document inconsistencies in the blood circulation of the retina. It is very similar to a coronary angiogram for checking blood circulation to the heart. It involves the injection of a dye called Fluorescein into a vein of the arm following which repeated photos of the retina are taken. It is very useful in the management of diabetic retinopathy.
3. High definition Optical Coherence Tomography (HD-OCT) – Zeiss, USA
We have come a long way in understanding what the retina looks like. Imagine being able to take a slice of the back of the eye without even touching it. The Zeiss, Optical Coherence Tomography uses a beam of light and its reflection to obtain cross-sectional images which provide information about the different layers of the retina.
4. B-scan Ultrasonography – Quantel, France
This procedure involves use of high-frequency sound waves to examine the eye when normal view is obscured by hemorrhage or cataracts.
With Gold standard single spot delivery system we have the technology to treat many retinal diseases like diabetic retinopathy, retinal holes and tears, without the need of performing invasive surgery. The addition of an Indirect Ophthalmoscope delivery system enables us to reach even the toughest corners of the retina. Most of these are performed under topical anesthesia (drops) and as outpatient procedures.
A lot has changed in the area of intra vitreal injections and implants. These have come a long way in the management of conditions like age related macular degeneration, diabetic macular edema and vascular occlusions in the eye. We routinely inject Lucentis (Ranibizumab), Avastin (Bevacizumab), Macugen (Pegaptinib Sodium), Ozurdex (steroid implant) and Triamcinolone acetonide (Depot steroid).
A wide range of retinal procedures are performed with the Alcon Constellation system which is the top of the line vitrectomy system. We possess the capability to perform sutureless vitrectomy even in the most complex of cases. We can now perform procedures like:
Complex retinal detachment surgery
Dislocated nucleus and intraocular lenses retrieval
Scleral buckle and scleral fixated lenses
Most common degenerative change in the vitreous. Appearance of coarse aggregate material which moves freely in the vitreous.
Causes: Myopic degeneration, Retinotis pigmentosa.
Post inflammatory condition following ureitis.
Trauma or Radiation
Posterior Vitreous degeneration
Separation of the vitreous from the back of the eye. Vitreous shrinks causing development of cloudy clumps in vitreous.
Symptoms: Floaters and flashes
Any non transparent structure present in the vitreous it will form an opacity due to its transparent nature.
1. Inflammatory vitreous opacities: Exudates paired into the vitreous in anterior ureitis and posterior ureitis
2. Amyloid degeneration: Amorphous amyloid material is deposited in the vitreous.
3. Asteroid hyalosis: It is some small rounded bodies suspended in the vitreous gel. It is formed due to accumulation of calcium containing lipid.
Besides we have a full time vitreo retinal specialist with us to take care of your retinal needs.
