Objective Eye Examination

Objective eye examination is a type of medical examination that involves the use of specialized instruments to examine the eye. It is an important part of a comprehensive eye exam and is used to diagnose and monitor a wide range of eye conditions.

There are several types of instruments used in objective eye examination, including the ophthalmoscope, the slit-lamp biomicroscope, the gonioscope, and the tonometer. Each of these instruments is designed to examine different structures and functions of the eye.

The ophthalmoscope is a handheld instrument that is used to examine the inside of the eye, including the retina, optic nerve, and blood vessels. It consists of a light source and a lens system that allows the examiner to see the inside of the eye in great detail. The ophthalmoscope is an important tool for diagnosing and monitoring eye conditions such as glaucoma, diabetic retinopathy, and age-related macular degeneration.

The slit-lamp biomicroscope is a specialized instrument that is used to examine the front part of the eye, including the eyelids, conjunctiva, cornea, iris, and lens. It consists of a high-intensity light source, a binocular microscope, and a movable table on which the patient's head is rested. The slit-lamp is an important tool for diagnosing and monitoring a wide range of eye conditions, including cataracts, glaucoma, and dry eye syndrome.

The gonioscope is a specialized instrument that is used to examine the angle of the eye, where the iris (the colored part of the eye) meets the cornea (the clear front part of the eye). The gonioscope is an important tool for diagnosing and monitoring glaucoma, a group of diseases that can damage the optic nerve and lead to vision loss.

The tonometer is an instrument that is used to measure intraocular pressure (IOP), the pressure inside the eye. Elevated IOP is an important risk factor for the development and progression of glaucoma, and the tonometer is an important tool for diagnosing and monitoring glaucoma. There are several types of tonometers, including the non-contact tonometer and the applanation tonometer.

Objective eye examination is an important tool for diagnosing and monitoring eye conditions, and it can provide more detailed and accurate information about the eye than subjective eye examination, which relies on the patient's subjective experience. However, objective eye examination has some limitations, and it is usually used in combination with subjective eye examination to provide a complete picture of the eye and the patient's eye health.

Regular eye exams are important for maintaining good eye health and for detecting and treating eye conditions early, before they cause permanent damage. If an eye condition is detected during an objective eye examination, treatment may involve medications, surgery, or other interventions, depending on the specific condition.

ABETALIPOPROTEINEMIA (BASSEN-KORNZWEIG SYNDROME) Retinopathy

Image
Abetalipoproteinemia, also known as Bassen-Kornzweig syndrome, is a rare genetic disorder that affects the body's ability to absorb and transport fats and fat-soluble vitamins. One of the ways that abetalipoproteinemia can affect the eyes is by causing retinitis pigmentosa, a condition that causes vision loss. Retinitis pigmentosa is a degenerative eye disease that affects the retina (the light-sensitive layer at the back of the eye). It is characterized by the gradual loss of photoreceptor cells (cells that detect light and send signals to the brain) and the accumulation of pigment in the retina. This can cause vision loss and may lead to blindness in severe cases. Abetalipoproteinemia can also cause optic atrophy, a condition in which the optic nerve (the nerve that carries visual information from the eye to the brain) becomes thin and weak. This can cause vision loss and other visual problems. In conclusion, abetalipoproteinemia can affect the eyes by causing reti...

What is myopia?

Image
Myopia is nearsightedness and this condition of eye occurs when the power of eye is increased from the normal powers of eye. The normal powers of eye is 58DS and the eye with >58DS eye power will be marked as myopic eye.  Definition   When parallel light rays coming from the infinity focus Infront of the retina while the accommodation should be at rest this condition of eye is known as myopia.

Scleritis

Scleritis 👌is a painful inflammation (swelling) the sclera. The tough, fibrous tissues of the sclera form a protective outer layer for the eye and make up 83 percent of the eye’s surface. In almost half of all cases, scleritis is associated with an underlying autoimmune disorder such as rheumatoid arthritis. There are two main types of scleritis: anterior and posterior. Anterior scleritis, the most common type, affects the front portion of the sclera. There are three types of anterior scleritis: Diffuse scleritis is the most common type and fortunately the most treatable. This type displays widespread redness and inflammation throughout the whole or a portion of the front portion of the sclera.     Nodular scleritis, is characterized by the presence of nodules , often tender to the touch, on the surface of the eye.     Necrotizing scleritis is the most severe form of anterior scleritis. It has the ability to destroy scleral tissues an...
