Optical coherence tomography ( OCT) is an imaging technique that uses interferometry with short- coherence-length light to obtain micrometer-level depth resolution and uses transverse scanning of the light beam to form two- and three-dimensional images from light reflected from within biological tissue or other scattering media. Short-coherence-length light can be obtained using a ...
He established the first eye hospital in the Philippines, De Ocampo Eye Hospital (1952) and the first Filipino President of the Philippine Ophthalmological Society (1958). He was the first Filipino to design a corneal dissector that was manufactured in the US. He received the Jose Rizal Medal [3] in Ophthalmology from the Asia Pacific Academy of Ophthalmology [4] and was named National ...
Optometry is a specialized health care profession that involves examining the eyes and related structures for defects or abnormalities. Optometrists are health care professionals who typically provide comprehensive eye care. In the United States and Canada, optometrists are those that hold a Doctor of Optometry degree.
Ophthalmologists prescribe medications to treat ailments, such as eye diseases, implement laser therapy, and perform surgery when needed. [5] Ophthalmologists provide both primary and specialty eye care—medical and surgical. [5] Most ophthalmologists participate in academic research on eye diseases at some point in their training and many include research as part of their career. [6 ...
The visual system is associated with the eye and functionally divided into the optical system (including cornea and lens) and the neural system (including the retina and visual cortex ). The visual system performs a number of complex tasks based on the image forming functionality of the eye, including the formation of monocular images, the ...
An eye chart is a chart used to measure visual acuity comprising lines of optotypes in ranges of sizes. Optotypes are the letters or symbols shown on an eye chart. [1] Eye charts are often used by health care professionals, such as optometrists, physicians and nurses, to screen persons for vision impairment. Ophthalmologists, physicians who specialize in the eye, also use eye charts to monitor ...
Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the anterior curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye's refractive power, [1] its topography is of critical importance in determining the quality of vision and corneal health.
A cataract is a cloudy area in the lens of the eye that leads to a decrease in vision of the eye. [1] [7] Cataracts often develop slowly and can affect one or both eyes. [1] Symptoms may include faded colours, blurry or double vision, halos around light, trouble with bright lights, and difficulty seeing at night. [1] This may result in trouble driving, reading, or recognizing faces. [8] Poor ...
