Vitrectomy is a surgical procedure in which the vitreous gel that fills the posterior chamber/cavity of the eye is removed to treat eye problems associated with retina or the vitreous. This surgery offers better access to the retina of the eye for different treatments like repair of retinal detachments, removal of scar tissue and treatment…
Optical Coherence Tomography (OCT) in ophthalmology is an emerging technology and is used to obtain high-resolution cross-sectional images of the nerve layer on the inside of the eye, the retina. It is a non-invasive imaging technology. This technology provides images on the micron scale in real time. The retinal layers can be differentiated, and the…
Intravitreal injections The vitreous of the eye is an avascular, gelatinous and hydrated body that contains 98% water. The characteristics of this layer changes with age. With the advancing age, the vitreous becomes more liquid and mobile. Hence, the most effective way to provide high concentrations of therapeutic agents into the eye is through targeted…
Diabetic macular edema (DME) is a serious and often overlooked complication of diabetes that can lead to significant vision problems. Many diabetics may not even realise that they are at risk for this condition.
A rather frequent eye illness impacting the central vision, age-related macular degeneration, is a common eye disease that affects the central vision and is particularly common among older people. Thanks to this, such routine processes as reading, driving, and face recognition may be extremely difficult. A person at risk ought to be familiar with the…
The macular hole occurs most frequently in the elderly. Early detection and early treatment ensures better chances of gain in visual acuity.
Cystoid macular oedema is a painless condition which affects the macula – the central part of the retina (Figure 1.1 and 1.2). This condition occurs when fluid collects in the tissue at the back of the eye, including the area responsible for our central vision. This accumulation of multiple pockets of fluid as cysts in…
Diabetic retinopathy is a serious eye condition that affects people with diabetes. It occurs when high blood sugar levels damage the blood vessels in the retina, the light-sensitive layer at the back of the eye. Over time, if untreated, this can lead to vision loss and even blindness. One of the most common causes of…
Millions of people across the globe wear contact lenses to enjoy a clear full field vision, to enhance their cosmetic appearance, or for therapeutic purposes.
Sub-threshold laser refers to the application of sub-visible burns during retinal laser therapy, thereby producing an effect only at the cellular level without causing any visible clinical burns.
