Retina is the light sensitive layer of nerve tissue in the back of the eye. It is a transparent innermost linning in the back of the eye ball.. The image is perceived here and transmitted to the brain by the optic nerve. The vitreous is the clear gel that fills ¾ of the eye ball behind the lens.
The Vitreous gel can become opaque due to blood - a condition called 'Vitreous hemorrhage. This condition can occur in diabetics following injury and in other conditions.
Vitreoretinal disorders account for blindness following cataract and related blindness in our country
Diseases of retina can affect any age. Premature infants can be affected by a disease called - ROP (Retinopathy of pre-maturity). Heredity and age related degenerations can affect the retina - especially the central most sensitive part of the retina called 'macula'. The retina can detach from the back of the eye - a condition called 'Retinal Detachment. Retinal detachment often associated with high myopia and following cataract extraction , diabetic retinopathy, vascular retinopathies. Retinal detachments can sometimes be prevented by recognising the risk factors early such as peripheral degenerations and retinal breaks. Prompt deTIOtion and treatment help to achieve good visual recovery.
Diabetic retinopathy, another important cause of blindness can be controlled by Laser Photocoagulation . Likewise early surgical treatment (Vitrectomy) is necessary in most cases of endophthalmitis.
Other retinal vascular diseases particularly retinal vasculitis, venous occlusive diseases are other condition needing Laser Photocoagulation and surgery. Retinopathy of prematurity, a potential cause of childhood blindness which needs timely Laser treatment and surgery.
Age-related Macular Degeneration (AMD) is the main cause of blindness and severe visual impairment in the developed world affecting approximately 25-30 million people globally. It affects the central most part of the retina called macula. Given its potentially devastating effect on an indivisual, two elements are essential in tackling the disease. Early deTIOtion is vital, particularly in the case of the most aggressive form of AMD (wet AMD) where treatment can halt the progress of the disease. The provision of low vision rehabilitation.
Management of vitreo-retinal disorders in the developing world is extremely difficult due to a spectrum of problems including limited resources available for effective vireoretinal surgery, scarcity of sub speciality trained ophthalmologist and lack of patient access to timely ophthalmic care.
The Institute has excellent structural facilities with modern equipments as well as diagnostic therapeutic and ancillary support services such as photography, angiography, ultrasonography, Optical Coherence Tomography and photocoagulation facilities. TIO has been providing a regular vitreoretinal services since 2000, with a focus on extending its services to the underserved population in the developing world.
The treatments available at TIO are Laser Photocoagulation and Complex Vitreoretinal Surgery. The Vitreoretinal unit is one of the busiest setup in the country.
