OCT (Optical Coherence Tomography): 3D imaging of the Macula (Most sensitive and main part responsible for the clear vision) and Optic Disc of the Retina, helpful to evaluate thickness of all the layers. Based on the cross-section scan many retinal pathologies can be detected eg. Diabetic macular edema, CRVO, ARMD, Macular Hole.
FFA (Fundus Fluorescein Angiography): Is a photographic procedure to visualise the tiny blood vessels of the Retina. Fluorescein dye (Orange coloured) is injected and serial photography by a specialist is captured, based on which retinal conditions and their severity can be diagnosed promptly.
Mainly useful in Diabeic Retinopathy, Vein Occlusion, Choroiditis, ARMD, Central serous retinopathy.
Laser Therapy: Retinal lasers have been specially designed to be able to pass through non-retinal tissue (the lens and cornea) without damaging them. Retinal disease is primarily treated using a thermal laser. The light energy is absorbed by specific tissue and is converted to heat with this type of laser.
The heat causes a very small area of damage to the retina. As the eye heals from this small area of damage the scar helps to correct the underlying retinal disease.
Thermal laser can be used to seal retinal tears, close leaking blood vessels or to break down abnormal tissue or blood vessels.
Intravitreal Injections: 
An intravitreal injection is a procedure to place a medication directly into the space in the back of the eye called the vitreous cavity. The procedure is usually performed by a trained retina specialist in the operation theatre. It reduces the macular edema, so vision is regained after proper dosage of these injections.
Intravitreal injections are used to administer medications to treat a variety of retinal conditions. Age-related macular degeneration (AMD), diabetic retinopathy and retinal vein occlusion are the most common conditions treated with intravitreal anti-VEGF drugs. Intravitreal steroids are used in some eyes with diabetic retinopathy, retinal vein occlusion and uveitis.
Microincisional Vitrectomy Surgery (MIVS): Vitrectomy is a surgical procedure undertaken by a specialist where the vitreous humor gel that fills the eye cavity is removed to provide better access to the retina. Once surgery is complete, saline, gas bubble or silicone oil may be injected into the vitreous gel to help hold the retina in position.
This allows for a variety of repairs, including the repair of Rhegmatogenous retinal detachments, Tractional retinal detachment due to advanced diabetic eye disease, Vitreous Haemorrhage, Intraocular foreign body removal, and as a treatment of macular hole.
