Retina
Rotary Eye Institute, Navsari, Retina clinic has state-of-the-art equipment for investigation and treatment of various Vitreo retinal diseases.
Retina is a thin layer of tissue that lines the back of the eye on the inside. It is located near the optic nerve.
The function of retina is to receive light that the lens has focused, convert the light into neural signals, and send these signals on to the brain for visual recognition.
Vitreous is clear, jelly-like substance that fills the middle of the eye. Also called the vitreous humor. It maintains the structural integrity of the eyeball.
Diabetic Retinopathy:
Over a period of time, patients, who have diabetes tend to have changes in their blood vessels(capillaries) which initially leak blood and fluid into the retinal layers, causing swelling and latter may develop new vessels which are very fragile and they can easily bleed into the vitreous cavity, causing sudden loss of vision.
Retinal detachment:
Retinal detachment is caused by the presence of fluid under the retina, which usually is secondary to a retinal break. There may also be other causes of RD (exudative retinal detachments and tractional retinal detachments). It is often accompanied by the sudden onset of symptoms such as floaters and flashing lights and sudden defective vision.
Macular degeneration:
In this case, the center of the eye, which enables, best vision begins to deteriorate. There are two types of macular degeneration — wet macular degeneration and dry macular degeneration. Dry form is more common than wet but dry form can become wet form progressively.
Vascular occlusive disease:
Retinal arteries and veins can get occluded due to various systemic diseases. This occlusion can cause bleeding and swelling in the eye, which in turn causes sudden defective vision. Vision loss in central artery occlusions is usually permanent if treatment is delayed.
Epiretinal membrane:
Epiretinal membrane is a delicate tissue-like scar or membrane that looks like crinkled cellophane lying on top of the retina. This membrane constricts the retina, which distorts one’s vision. In this case scenario, objects may appear blurred or crooked.
The clinics are well equipped with trained doctors and modern technology to diagnose and treat a multitude of vitreo retinal conditions. Treatment includes both medical and surgical interventions.
State-of-the-art equipment for investigation and diagnosis of various Vitreo retinal diseases include:
• Fundus Fluorescein Angiography (FFA)
• Optical Coherence Tomography (OCT)
• Ultrasonography
Various medical and surgical treatments are available for the above mentioned conditions. Complicated vitreo-retinal surgeries are performed successfully everyday. Various types of lasers and intravitreal injections are also available.
Various types of lasers are used to stabilise retinal diseases like diabetic retinopathy, vascular diseases, tumours, retinopathy of prematurity and many more. These are delivered either with the help of a slit lamp or by indirect ophthalmoscope. Diode, frequency doubled Nd:Yag laser, argon laser, subthreshold micropulse laser are available.
Transpupillary thermotherapy is used in tumours to damage the abnormally growing vessels while causing minimal trauma to normal retina.
Intravitreal anti-VEGF injections are used to treat conditions in which there is growth of new abnormal leaky vessels due to underlying disease which has caused ischaemia of the retina. It can also be used in cases of macula edema. Intravitreal steroids can also be used to effectively treat macular edema. Intravitreal antibiotics are used to treat grave ocular infections to effectively deliver these drugs into the eyeball.
Pars plana vitrectomy with silicon oil or gas injection, core vitrectomy, epiretinal membrane peeling, macular hole surgery, scleral buckling and intraocular foreign body removal are performed regularly in H. V. Desai eye hospital. Modern day surgeries use smaller size trocar/ cannula systems like 23G, 25G and 27G. These help in better wound reconstruction and healing and avoid post- operative infections. All the vitreous-retinal surgeries conducted at H. V. Desai Eye Hospital are performed by highly skilled surgeons, who have years of valuable experience in this field.
