Vitreo – Retinal Services

Medical retina:

Message : The department of Vitreo - Retina deals with ocular conditions affecting the posterior segment of the eye. Besides indirect Ophthalmoscopy and slit lamp biomicroscopy, specialized equipments like B-scan ultrasonography UBM (Ultrasound Biomicroscopy) and Digital fundus fluorescien angiography (FFA) aid in diagnosis and treatment of complex vitreo-retinal diseases. Fundus Fluorescein Angiography is a diagnostic procedure where a dye is injected into a vein and sets of digital photographs are taken to display the blood vessels of the Retina. It shows any abnormal blood vessels and any leaking spots causing retinal diseases. Optical Coherence Tomography (OCT): -The thickness of the retina can be accurately measured by Optical Coherence Tomography (OCT). This recently developed instrument allows for topographical analysis of irregularities in contour of the retinal surface as well as painless measurement of the retinal thickness down to a small fraction of a millimeter. OCT has become an important tool for the diagnosis and for planning for the line of treatment and follow ups in diseases like diabetic retinopathy, age related macular degeneration, Retinal Venous Occlusion. Anti-VEGFs refer to a category of drugs which work by targeting a protein that is needed when new blood vessels form. Blocking VEGF can reduce the growth of new blood vessels, slow their leakage and slow down vision loss in macular edema with diabetic Retinopathy, Retinal Venous Occlusion, and Age Related Macular Degeneration. Intravitreal anti-VEGF injections like Avastin / Lucentis are given regularly.
Recently Intravitreal Ozurdex is given regularly in Retinal venous occlusion with macular oedema and Non-infectious Uveitis. Photo Dynamic Therapy: -Photodynamic therapy is a special form of Laser treatment for Choroidal Neo Vascular Membrane (CNVM) due to various causes like – Age related Macular Degeneration (AMD), High Myopia, idiopathic and post inflammatory. This therapy is based on stimulation / activation of a photosensitive dye by exposure to a light (laser) of specific wavelength, which then closes the new vessels. Retinal lasers are performed using green laser (iris medical) for Retinal Holes or tears, Diabetic Retinopathy, Retinal Venous Occlusion, Eales Disease, and Selected Cases of Central Serous Retinopathy.

Surgical retina :

The surgical Retina department has state of the art surgical equipments in operation theatre like Moller- Wedel microscope and ACCURUS surgical system with 3-D technology & high performance probes. 23-gauge micro-incision vitrectomy probe has High speed 2500 cpm reducing traction, increasing stiffness & stability, more precise shaving at Retina due to 50% closer port to the tip than 20 guage probe .It has ideal flow rate. 25-gauge micro-incision vitrectomy probe is light weight pneumatic 1500 cpm designed for reducing traction and increasing stability when cutting close to Retina. It has smooth, stable, guillotine-cutting action with excellent flow rates. These high performance probes reduce the size of scleral incisions to a fraction of what was possible with standard vitrectomy probes and in this way provide more rapid postoperative rehabilitation and a reduced risk of complications Advantages of micro-incision vitrectomy include greater postoperative comfort and reduced ocular hyperemia. In Addition, most procedures do not require sutures, so there is faster postoperative recovery. As a result, patients require less topical medication after surgery and therefore have less risk of steroid-induced ocular hypertension. Main indication for 25 gauge vitrectomy is for glaucoma filtering blebs where 25 gauge is essential to allow for a sutureless incision that helps to preserve the bleb.
