A 30year old lady from Nanded presented with sudden onset redness and blurring of vision in her left eye for 1week. On examination, her right eye vision was 6/6 which is normal and left eye vision was 6/60. Her left eye showed a severe reaction inside the eye (Figure 1a and 1b.)
Cataracts are thought to be synonymous with ageing process. There are different types of cataracts, and most do develop slowly. However, posterior subcapsular cataracts result in faster deterioration of vision in comparison to the other types. However, they are treatable, thanks to advancements in the field of ophthalmic surgery.
A cataract is clouding of the natural crystalline lens of the eye. This obstructs the passage of light onto the retina at the back of the eye and affects the person’s ability to see clearly. Generally, cataract is seen in old age and such type of cataract is known as a senile cataract. If left untreated cataract leads to blindness.
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 thickness of the retina can be measured with optical coherence tomography.
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 the macular area, is known as cystoid macular oedema.
One of our most crucial and valuable senses is ‘vision’. Eyes are made up of several parts and all of them are equally important for vision. When light enters into the eye, it is directed in the right amount towards the eye lens. The complex anatomy of the eye converts this incoming light into electrical energy.
Generally, tuberculosis is known to affect the pulmonary system, but in some cases, it can also affect other organs (extra-pulmonary) like eyes.
How common is tuberculosis? The magnitude of the problem.
The term “Ocular Tuberculosis” is defined as an extra-pulmonary form of the disease that includes any infection in
