Vitreoretinal surgery is performed in the part of the eye where the vitreous and retina are located. The vitreous is a jelly-like substance filling the cavity between the lens of the eye and the retina. The purpose of vitreoretinal surgery is to restore, preserve and improve vision for a wide range of conditions. Vitreoretinal eye surgery refers to a group of advanced, highly delicate procedures that are done deep inside the eye’s interior. Vitreoretinal surgeries have high success rates, and patients should experience improved vision in just a few weeks. For most people, sight is either improved or restored. This is a positive outcome for those who would otherwise be left with permanent vision loss. The Vitreoretinal Service at Sri Sankaradeva Nethralaya offers expertise in the diagnostic, medical and surgical retina. Diagnostics forming the backbone of every successful treatment, we provide a very advanced small pupil fundus camera for Fundus Fluorescein Angiography and a precise Optical Coherence Tomography system. Treatment of all retinopathies affecting the eye due to diabetes, hypertension, vascular malformations, and age-related macular degeneration is possible with laser and anti-VEGF injections or surgery depending on the requirement. The retina laser service houses an advanced Argon-Laser System for Retinal Photocoagulation and also the Photo Dynamic Therapy laser system for treatment of Age-Related Macular Degeneration. The department also boasts of the latest Optos imaging system which helps in pan imaging of the retina. For Surgical treatment the department is equipped with the advanced Micro Incision Vitreous surgery system and with its team of expert surgeons caters to advanced retina surgery requirements including Retina Detachments, Ocular Trauma, Diabetic Micro Incision Vitreous surgery, Macular Hole surgery etc.
VITREO-RETINA Services available at Sri Sankaradeva Nethralaya
RETINAL REATTACHMENT SURGERIES – Retinal detachment repair is the eye surgery to place a retina back into its normal position. The retina is the light-sensitive tissue in the back of the eye. Detachment means that it has pulled away from the layers of tissue around it.
SUTURELESS VITRECTOMY – Sutureless Vvitrectomy has rapidly been accepted as an essential part of a vitreoretinal surgical setup. The size and structure of the wound along with near intact conjunctival covering makes the incision self-sealing and safe.
ENDOLASER APPLICATION - Endolaser, or Endovenous Laser Treatment, is a minimally invasive technique for varicose veins. The treatment can be performed under a local anaesthetic, without the need for sedation.
TC CRYOPEXY – Cryopexy is an outpatient surgical procedure that uses extreme cold therapy or freezing to treat retinal tears and other retinal conditions. It works by creating scar tissue that seals the tear to help prevent further damage or a complete retinal detachment.
INTRAOCULAR FOREIGN BODY REMOVAL - An intraocular foreign body represents a medical emergency, especially metal fragments arising from hammering farmyard equipment, soil-contaminated items and machinery. The foreign body is normally removed through a surgical incision depending on the location and size of the foreign body.
SILICONE OIL INJECTION/REMOVAL - Silicone oil (SO) is a vitreous substitute which is widely used to provide long term intraocular tamponade in retinal surgery. Transient or permanent rise in intraocular pressure is a common complication of silicone oil injection following pars plana vitrectomy. The silicone oil should be removed no longer than 6 months after its injection, and the best timing to remove the oil is 2 to 3 months.
EXPANSILE GAS (C3F8/SF6) INJECTION – Intravitreal C3F8gas injection is an inexpensive and promising minimally invasive option for the treatment of symptomatic and persistent vitreomacular traction with or without a macular hole.
PAN RETINAL PHOTOCOAGULATION - Panretinal Photocoagulation (PRP) is a mainstay of therapy for retinal ischemic disease. The procedure involves creating thermal burns in the peripheral retina leading to tissue coagulation, the overall consequence of which is improved retinal oxygenation. Panretinal photocoagulation (PRP) is an extensive laser treatment applied to the peripheral retina inside the eye. This treatment is recommended when abnormal blood vessels are growing inside the eye.
PATTERN LASER PHOTOCOAGULATION (PASCAL PHOTOCOAGULATOR) – The Pattern Scanning Laser (PASCAL) Photocoagulator is used for pan-retinal, focal, and macular grid photocoagulation in the setting of proliferative and non-proliferative Diabetic Retinopathy. It helps to provide a more precise and predictable pre-determined pattern array resulting in enhanced uniformity of laser treatment with less discomfort to the patient and diminished operator fatigue.
PHOTODYNAMIC THERAPY (PDT) - Photodynamic therapy (PDT) is a treatment that involves light-sensitive medicine and a light source to destroy abnormal cells. It can be used to treat some skin and eye conditions, as well as certain types of cancer.
TRANS PUPILLARY THERMOTHERAPY (TTT) - Transpupillary thermotherapy (TTT) is a technique in which low-level heat is delivered through the pupil to the choroid and retinal pigment epithelium using a modified diode laser. TTT is proposed as a treatment option for retinoblastoma and choroidal melanoma by delivering heat directly to the tumor surface via infrared wavelengths of light resulting in tumor necrosis.
ANTI-VEGF INJECTIONS - Anti–Vascular Endothelial Growth Factor Injections are part of anti-VEGF medication, which are used to block vascular endothelial growth factor. Anti-VEGF treatment is given as an injection into the white of the eye (the sclera). The drug is injected directly into the vitreous, the jelly that fills the eye. This is called an “intravitreal” injection. The procedure is generally very straightforward and quick and isn't usually painful.
