Slit lamp fundoscopy
Evaluation of the disc, macula and periphery of the retina using the slit lamp and fundus aspheric lens 90D, 78D, 60D or 120D.
Lenses of slit lamp biomicroscope & indirect ophthalmoscope.
This document discusses different lenses used for ophthalmic examination, including Volk double aspheric lenses, Goldmann three mirror lenses, and indirect ophthalmoscope lenses. Volk lenses come in 60D, 78D, and 90D powers and are used for slit lamp biomicroscopy. The 60D provides high magnification of the posterior pole, while the 78D is for general diagnosis and the 90D is for small pupils. Goldmann three mirror lenses provide a 3D view of the anterior chamber and fundus and require a coupling agent. Indirect lenses act as condensing lenses, with higher powered lenses providing less magnification but wider field of view.

Retinoscope, optom faslu muhammed
Retinoscopy is a objective method of evaluating refractive error by neutralizing the light reflected from the retina. It does not depend on the patient's vision or judgment. During retinoscopy, light is shone into the patient's eye from a retinoscope as they look at a distant target. The direction the light travels across the pupil indicates the eye's refractive state - emmetropia shows light traveling infinity, hyperopia beyond infinity, and myopia less than infinity. Retinoscopy can be performed with either a plane mirror retinoscope or a self-illuminated streak retinoscope. The examiner observes the red reflex in the pupil and moves the retinoscope until the reflex is neutralized to determine the
Ophthalmoscopy
Direct ophthalmoscopy allows examination of the inside of the eye using a handheld instrument with magnifying lenses. It provides an upright 15x magnification of about 50-70% of the fundus. Indirect ophthalmoscopy uses a head-mounted light and handheld lens to provide an inverted image with a wider field of view. Both methods allow inspection of the retina and other internal eye structures but direct ophthalmoscopy is more portable with better patient compliance as it does not require painful eye indentation.
Fundus examination
The document summarizes different techniques used to examine the fundus of the eye, including:
1. Direct ophthalmoscopy provides an upright 15x view of the posterior pole but no stereopsis. Indirect ophthalmoscopy uses lenses from 14-30D for an inverted 40-50 degree view with stereopsis.
2. Slit lamp biomicroscopy provides a 30-40 degree inverted view at higher magnifications up to 16x using a +78D lens.
3. A -55D lens provides a virtual upright view for examining the optic nerve and retina through dilated pupils. A contact lens combines high magnification and stereopsis for detailed macular exams.

direct ophthalmoscope
The direct ophthalmoscope allows an examiner to perform a preliminary examination of the internal eye including the retina and optic disc. It works by focusing light through a 45 degree mirror into the patient's eye. The reflected light from the retina passes back through the mirror and forms an erect, magnified image that the examiner can view. The size and clarity of the image provides information about the patient's refractive error and can detect conditions like cataracts, retinal detachments, or tumors. By observing how an opacity moves with the patient's eye movements, its location relative to the pupil can be determined.
Retinoscopy
Retinoscopy is a technique used to objectively measure the refractive error of the eye. Light is directed into the patient's eye to illuminate the retina, and the observer views the resulting reflex to determine the refractive state. There are different types of retinoscopes and techniques used. By observing properties of the fundal reflex such as direction and speed of motion, the observer can determine if the eye is emmetropic, hyperopic, or myopic, and approximately how much refractive error is present. Further testing is done to refine the prescription and determine any astigmatism. Retinoscopy provides an efficient initial objective refraction.

Retinoscopy
Retinoscopy is an objective method of determining a person's refractive error by examining how light is reflected from the retina. It can be used when subjective refraction is not possible, such as for babies or those unable to communicate. During retinoscopy, a light is shined into the eye and the reflection is observed to determine if the light moves with or against the observer's motion, indicating myopia or hyperopia. Various factors including pupil size, media clarity, and accommodation state can affect the results. Retinoscopy is performed at a standard working distance and results are adjusted based on this distance and cycloplegic effects to give the final refractive prescription.

There are two common types - Zeiss and Haag Streit - which differ in the position of the light source. Various illumination techniques like diffuse, direct, retro-illumination and specular reflection are used to visualize different ocular structures. The slit lamp enables in-vivo examination of the anterior segment in 3D and is invaluable for diagnostic and surgical procedures.

CORNEAL EDEMA.pptx
Corneal edema occurs when the corneal thickness increases and transparency decreases due to a buildup of fluid between the corneal layers. Fluid accumulation can be caused by inflammation from conditions like corneal ulcers or iridocyclitis, trauma from mechanical injuries or surgery, increased intraocular pressure, corneal hypoxia, or dystrophic eye conditions. Symptoms include decreased vision acuity and seeing colored halos. Treatment focuses on removing the excess fluid through the use of hot air, saline drops or ointment, or glycerin drops.
Presbyopia
Presbyopia is an age-related loss of the eye's ability to focus on near objects. It typically begins around age 40 and causes symptoms like eyestrain and headaches when reading. Tests like visual acuity and refraction exams are used to diagnose presbyopia. Treatment involves using appropriate corrective lenses matched to the patient's specific needs, like bifocals or progressive lenses, to bring their near vision point within a comfortable reading distance. Presbyopia is a natural part of aging and should not be overcorrected, as that can cause discomfort.
Aphakia
Aphakia is the absence of the crystalline lens in the eye. It can be congenital or acquired through cataract surgery. Patients with aphakia experience high hyperopia and a loss of accommodation. Treatment options include spectacle correction, contact lenses, intraocular lens implantation, or refractive corneal surgery. Each option has advantages and disadvantages related to image quality, comfort, risk of complications, and cost.

Myopia
This document defines and describes myopia (nearsightedness). There are several types of myopia depending on the mechanism, including axial, curvature, and index myopia. Clinically, myopia can be congenital, simple, or pathological depending on presentation. Pathological myopia develops in childhood, progresses significantly, and causes degenerative changes to the fundus. Myopia is diagnosed through visual acuity and refraction tests and treated with corrective lenses, contact lenses, or refractive surgery. Proper treatment depends on the type and severity of myopia.

ANATOMY & HISTOLOGY OF CONJUNCTIVA
The conjunctiva is a mucous membrane that lines the inner surface of the eyelids and covers the anterior portion of the eye. It has three parts - the marginal, tarsal, and orbital conjunctiva. The marginal conjunctiva extends from the eyelid margin to the subtarsal fold. The tarsal conjunctiva is firmly attached to the tarsal plate. The orbital conjunctiva lies loosely over underlying structures. Histologically, the conjunctiva has an epithelial layer, adenoid layer, and fibrous layer. The epithelial layers vary between regions from stratified squamous to columnar epithelium. The adenoid layer contains lymphocytes and the fibrous layer consists of collagen and elastic fibers with blood vessels and nerves
Hirschberg test
The Hirschberg test provides an objective estimate of the angle of a manifest squint by measuring the deviation of the corneal light reflex from the center of the pupil in the squinting eye when the patient fixates on a point light held 33cm away. Each millimeter of deviation roughly equals 7 degrees of squint, with 15 degrees indicated if the light reflex reaches the pupil border and 45 degrees if it reaches the limbus.
Maddox rod
1. The Maddox rod test uses a red or white lens with parallel cylinders to convert a point light source into a vertical streak of light, which is used to assess the type and size of strabismus.
2. The test procedure involves placing the Maddox rod in front of one eye to see a vertical streak while fixating on a distant light with both eyes. The relative position of the streak compared to the light indicates the type of strabismus.
3. The amount of strabismus is measured by adding prisms until the streak is seen passing through the light, indicating the strength of prism needed to align the eyes.
Maddox wing
The Maddox wing is an instrument used to measure the amount of near phoria at 33cm through dissociating two dissimilar images seen by each eye. To administer the test, the right eye views a red and white arrow on a scale while the left eye views only the numbers on the scale, with the patient identifying the number indicated by the arrows' positions. The test requires a brightly lit room and the patient wearing any needed optical correction.
Ophthalmoscope
Ophthalmoscopy is a test performed during an eye exam that allows a health professional to examine the interior structures of the eye, especially the retina, using an ophthalmoscope. There are two main types - direct ophthalmoscopy, where the health professional looks directly into the eye, and indirect ophthalmoscopy, where a light is shone into the eye so the health professional can view the retina through a lens. Ophthalmoscopy is used to check for signs of eye diseases and conditions like cataracts, macular degeneration, and retinal tears or detachments.

This particular slides consist of- what is hypotension,what are it's causes and it's effect on body, risk factors, symptoms,complications, diagnosis and role of physiotherapy in it.
This slide is very helpful for physiotherapy students and also for other medical and healthcare students.
Here is the summary of hypotension:
Hypotension, or low blood pressure, is when the pressure of blood circulating in the body is lower than normal or expected. It's only a problem if it negatively impacts the body and causes symptoms. Normal blood pressure is usually between 90/60 mmHg and 120/80 mmHg, but pressures below 90/60 are generally considered hypotensive.

Slit lamp
- 1. Slit lamp
- 3. BASICS What are the three systems present in a slit lamp ? OBSERVATION SYSTEM ILLUMINATION SYSTEM MECHANICAL SYSTEM
- 9. DIFFUSE ILLUMINATIoN Light is spread evenly over the entire observed surface The beam is completely open The light is directed on the eye at 45 º angle The microscope is directed straight ahead The structures observed are: eyelids, eyelashes, conjunctiva, sclera, pattern of redness, iris, pupil, gross pathology and media opacities
- 10. Optic section A narrow focal slit beam is projected at a 45-60˚ angle It cuts an optical section through the cornea like a knife With this technique it is possible to locate the layer of the pathological changes Magnification approximately 10X Width: Narrow slit 1mm
- 11. Parallelepiped Default method of corneal evaluation Cornea is focusses obliquely in order to obtain a quadrilateral block of lght illuminating the cornea Beam about 2 mm width Medium to High magnification (10-25x) Can be used to examine corneal surface or stroma For ascertaining the depth of abrasion or foreign body
- 12. Conical beam Slit lamp is adjusted to smallest circular beam Projected at an angle of 42-90º through the anterior chamber The strongest reflection is possible at 90 º Used to visualize cells, flares, proteins or intra ocular foreign body
- 13. SCLEROTIC SCATTER A tall wide beam is directed onto the limbal area When the light is properly aligned with regard to the eye, a ring of light will appear around the cornea The light is absorbed and scattered through the cornea highlighting the pathology 10x magnification is usually used Corneal edema, opacities,infiltrates, foreign bodies
