1 Optical Equipment 1 1 Introduction And General Information .
2 Introduction
Optical instruments: instruments that reflect and refract light in order to form images by using Introduction mirrors, lenses and light. 3
There are many optical devices that are used to diagnose eye diseases or the rate of refractive error in the eye, including: Retinal camera Phoropter Applications of Optical Instruments: Ophthalmoscope Manual keratometer Tonometer Slit lamp Snellen chart Retinoscope 4
Retinal Cameras or Digital Fundus Cameras are used to capture images of the interior surface of the eye. It allows the diagnosis of many eye conditions like diabetes-related retinopathy, glaucoma and macular degeneration. Retinal camera 5
phoropter: is an instrument comprised of cylinders, prisms, and lenses that measures the eye's refractive error to help determine and eye prescription. Phoropter 7
8 Phoropter
Ophthalmoscopy: also called funduscopy, is a test that allows to see inside the fundus of the eye and other structures. It is determining the health of the retina, optic disc, and vitreous humor. Ophthalmoscopy Ophthalmoscopy 9
This instrument can give a precise examination of the radius of curvature of the anterior corneal surface. This measurement is used to fit contact lenses and to Manual Manual keratometer keratometer measure corneal changes. 10
Tonometry Tonometry: : is a test to measure the pressure inside your eyes. The test is used to screen for glaucoma. Tonometry Tonometry 11
Tonometry Tonometry 12
13 A slit lamp: is a microscope with a bright light used during an eye exam. It gives the different structures at the front of the eye and inside the eye. It s determining the health of eyes and eye disease. can see The sclera, slit lamp cornea, lens, retina.
14 Snellen chart: is an eye chart that can be used to measure visual acuity. Snellen chart Snellen chart
15 Retinoscopy: is a technique to obtain an objective measurement of the refractive error of a patient's eyes. Retinoscopy
