Ophthalmoscopes: A Vital Medical Device for Eye Examinations

The history of the ophthalmoscope dates back to the 1850s when Hermann von Helmholtz, a German physician and physicist, invented the first basic version to examine the interior of the human eye. Since then, the device has undergone many innovations and advancements. In 1890, American ophthalmologist Henry Gradle developed an improved version of the direct device which allowed for better retinal examinations. In the early 1900s, indirect ones became available which enabled eye inspection without contact with the patient's eyeball making examinations more comfortable. In the following decades, power sources were introduced to provide brighter illumination for viewing the fundus and photo capabilities were integrated to document findings. Modern ones today are highly portable, lightweight digital devices offering advanced imaging, magnification and illumination functions. Workings

Ophthalmoscopes utilize a combination of lenses and light sources to view the interior structures of the eye. Direct ones hold a lens near the patient's eye which reflects and magnifies the retinal image while the examiner views through an eyepiece. Indirect scopes project an inverted magnified image of the retina onto a lens placed on the patient's forehead, allowing the examiner to observe from a short distance. Both types focus a small bright light beam on the retina using lenses or an optic fiber bundle. Dioptic lenses enable viewing of both the illuminated retina and immediate surroundings simultaneously. Powered ones contain a battery that powers high-intensity LEDs or halogen bulbs. Digital models have cameras to photograph the retina electronically. Applications in Medical Screening and Diagnosis Routine eye examinations conventionally involve visualizing the retina, optic disc and macula using an ophthalmoscope. This helps detect signs of numerous common conditions. Diabetic retinopathy screenings rely heavily on retinal visualization via ophthalmoscopy. Changes indicative of the disease such as microaneurysms, hemorrhages and exudates can be spotted. These are indispensable for hypertensive retinopathy evaluation where they reveal arteriolar narrowing, silver wiring of vessels and optic disc edema. Papilledema, a swelling of the optic disc, is a key sign often picked up on ophthalmoscopy in conditions like brain tumors. Retinal detachments, tumors and occlusions can also be promptly diagnosed with these instruments. Ophthalmoscopic findings are regularly recorded to monitor progression or response to treatment over time. Applications in Research and Telemedicine Ophthalmoscopy makes significant contributions beyond clinical practice. Research in ocular diseases extensively utilizes information gathered through standardized retinal examinations using scopes. Digital retinal images obtained are stored in databases for large population studies analyzing risk factors. Technology partnerships have enabled “eyecams” that can tele-ophthalmoscopically transmit retinal photos from remote locations to expert reading centers, expanding access to specialty eye care. The US military uses tele-ophthalmoscopy to remotely screen troops for eye and systemic issues like hypertension. These are pivotal research tools, aiding discovery of pathological changes, disease mechanisms and treatment responses. Advancing scope technology itself drives retinal imaging research contributing to medicine.

Physical Examination of the Eye in Veterinary Medicine

A thorough ocular examination is an important diagnostic procedure in veterinary medicine. Primary and secondary ocular disease may occur. The changes seen in the eye may be related to another disease process, directing you to further diagnostics.

Before being able to perform a proper ocular examination, you must understand the anatomy of the species that you are examining. This post will largely focus on mammalian eyes.

Basic ocular anatomy includes: The cornea - clear tissue covering the front of the eye. The uvea (ciliary body, choroid, and iris) - vascular tissue of the eye. The iris is the coloured section surrounding the pupil. The lens - clear disc within the eye that is used to focus light. The retina - photoreceptors are present here. Light is converted into a signal for the brain to interpret as a visual. The sclera - the white connective tissue surrounding the globe. The optic nerve - carries nervous information to the brain.

Related structures include: The third eyelid (nictitating membrane). The eyelids and conjunctiva. The lacrimal glands - produce the watery portion of tears. The meibomian glands - produce the oily portion of tears.

Vision

The patient should be observed as they move around the examination room. Signs that the patient may be experiencing difficulty in seeing include reluctance to move, running into things, and high stepping.

Menace response: This test is performed by performing a threatening hand gesture heading towards the eye. The contralateral eye should be covered when performing this test. It is important to avoid pushing air/creating a breeze toward the patient as air stimulus alone may cause the patient to blink. You must avoid contact with the whiskers. A positive menace response is achieved when the patient blinks. The menace response is a learned response and is not present consistently in cats and dogs under the age of 3-4 months. Tests: peripheral and central visual pathways, visual cortex, CN7.

Pupillary light reflex: This test does NOT test vision as it is a subcortical reflex. This may be normal in a cortically blind animal. This test is performed by shining a light into the eye and observing the response of pupil size. This should be done with a bright light in a dimly lit room. Both direct (the eye in which light is being shined) and indirect (the contralateral eye) PLRs are observed. Both direct and indirect should be present when light is shined into either eye.  Birds and reptiles do not have a PLR. They are able to control the constriction and dilation of their pupils independent of light.

Dazzle: This test does NOT test vision as it is a subcortical reflex. This test is performed by intensely illuminating the eye. A positive dazzle response is achieved when the patient reacts to the light. This reaction can be a blink, third eyelid protrusion, head movement, or globe retraction. Tests: retina, CN2, CN7.

Periocular

Evaluate the orbits (bone surrounding the globe) for symmetry, deformity, or enlargement. Breed variations are important to understand during this portion of the examination. The orbital rim should be palpated to ensure no irregularities are missed.

The position and general movement of the eyes should be observed: Strabismus - abnormal alignment of the eyes. Nystagmus - rapid involuntary movement of the eyes.

Eyelids

Blink (palpebral) reflex: This test is performed by touching the skin near both corners of the eye. This should produce a blink response. The finger should be gently dragged across the closed eye to ensure that the patient is capable of holding their eye closed. Tests: CV7, orbicularis oculi muscle, CN2, CN5.

The eyelids should be observed for any abnormalities. Abnormalities may include: Masses or cysts. Entropion - rolling in of the eyelid. Ectropion - rolling out of the eyelid. Ectopic cilia - eyelashes in abnormal locations.

Conjunctiva

The upper and lower eyelids should be manually everted. This allows for evaluation of the tissue. Abnormalities may include: Increased vascularity. Lacerations or foreign bodies. Growths. Chemosis - edema.

Third eyelid

The third eyelid can often be extruded by placing gentle pressure on the tissues near the inner corner of the eye. Abnormalities may include: Prolapse of the gland - cherry eye. Conjunctivitis. Enlarged glands or lymphoid tissue.

Sclera

The sclera should be observed for changes in vasculature, colour, masses, or lacerations.

Cornea

The cornea should be avascular and unpigmented. It should be smooth. The cornea should be examined for change in transparency/opacity, vascularization, pigmentation, laceration/ulceration, masses, and foreign bodies.

Fluorescein stain: This stain is used to confirm the absence or presence of superficial ulcers. No corneal examination is complete without this test. The dye does not stick to the outer layer of the cornea as it is lipid selective. The corneal stroma, when exposed, allows rapid diffusion of the dye. An area of fluorescein retention is indicative of an epithelial defect such as an ulcer or erosion.

Anterior Chamber

A focal light source should be shined through the anterior chamber of the eye to examine the aqueous humor. When increased protein is present, the beam of light should appear to be passing through smoke. This is called aqueous flare and is indicative of uveitis. 

Lens

The lens should be transparent and avascular. The lens should be observed with an ophthalmoscope for opacities, position, and size.

Cataracts: Focal - localized within various parts of the lens. Nuclear cataracts are usually stationary. Equatorial cataracts are usually progressive. Immature cataract - involves more of the lens and causes blurred vision. Mature cataract - entire lens affected, vision loss.

Lenticular sclerosis: Begins to develop in dogs around 6 years of age. This is seen as a blue zone in the nucleus of the lens that does not impair visualization of the fundus.

Fundus

An ophthalmoscope is required for examination of the fundus. An examination can be performed without drug induced mydriasis (dilation of the iris) though it assists in complete examination. 

Abnormalities may include: Vascular patterns. Retinal detachment. Congestion or hemorrhage. Changes in pigmentation.

Tear Production

Tear film is essential in maintaining normal corneal health. When the cornea is not appropriately moisturized, ulcers and other pathology can result. 

The schirmer tear test is used to quantify the amount of aqueous tear portion present in each eye. This test does not evaluate the quality or make-up of the tears.  The test strip is placed in the lacrimal lake at the junction of the lateral and middle thirds of the lower eyelid. It is held in place for 60 seconds while the animal typically holds their eye closed. The test is not linear and therefore you cannot measure for 30 seconds and simply multiply by two. Normal values are > 15mm for cats and dogs. Other species may have species-specific values published.

Intraocular Pressure

This is measured with tonometry. Applanation tonometers, such as the tonopen, are very accurate. Normal IOP is 16.8 ± 4.0 mm Hg in dogs; 20.2 ± 5.5 in cats. Low IOP indicates uveitis while high IOP indicates glaucoma.

Indirect Fundoscopy

What is indirect fundoscopy, and how does it differ from direct fundoscopy?

Indirect fundoscopy involves using a condensing lens and a light source to view the fundus, creating an inverted and magnified image. In contrast, direct fundoscopy uses a handheld ophthalmoscope for a non-inverted, but less magnified view. Indirect fundoscopy allows for a more comprehensive examination of the peripheral retina.

Is indirect fundoscopy more commonly used in specific eye conditions?

Indirect fundoscopy is often preferred in cases where a more extensive view of the retina is required, such as in the assessment of peripheral retinal tears, detachments, or during surgical procedures. It provides a wider field of view compared to direct fundoscopy.

Ophthalmoscopy is the process for conducting test for eye examination using an ophthalmoscope to examine inside the fundus of eye. Ophthalmoscope helps in detection of abnormalities of retina, vitreous humor, optic disk, and lens and focuses a small beam of light though the pupil of patient’s eye. The ophthalmoscope devise comprises of eye piece, light illuminating source, battery handle and an aperture selector. India healthcare industry is developing at the rapid rate and there is high prevalence of eye diseases. Increase in the government initiatives to prevent blindness and cataract among the population such as National Program for Control of Blindness (NPCB) is another factor responsible for the growth of the ophthalmoscope market. Surge in healthcare expenditures for treatment of blindness, sight loss and sight-threatening conditions are expected to boost the demand for eye care and examination market which is further expected to drive the demand of ophthalmoscope market. Rise in occurrence of chronic diseases such as diabetes and hypertension can lead to retinopathy which is a significant factor accelerating the ophthalmoscope market growth.

Due to the ongoing pandemic COVID-19, lockdown restrictions were imposed all over the country. Complete shutdown was observed, and people started practicing social distancing and following the precautionary guidelines. Imposition of strict regulations and policies by leading authorities led to huge losses suffered by businesses. Also, the demand for medical devices have gone down. Manufacturing units were shut down and loss of availability of skilled labors led to market decline. Number of units imported or exported to other countries also suffered a setback. After the lifting of lockdown restrictions, companies are again operational and producing with lower volume and the market is expected to pick up the pace eventually.

However, lack of skilled healthcare professionals and eye surgeons may hamper the growth of ophthalmoscope market for the forecast period.

LCD Display Digital Chargeable Otoscope Ophthalmoscope Set

Types of otoscope

otoscope can be divided into two kinds of direct otoscope and indirect otoscope.

Direct ophthalmoscopy

Direct ophthalmoscopy can directly examine the fundus, without dilating the pupil, in a dark room for examination, the examiner's eye must be close to the patient's eye, with the right eye to examine the patient's right eye, the right hand holding the ophthalmoscope, sitting or standing on the right side of the patient, the left eye is the other way around, the doctor's other hand to open the patient's eyelid, first placed the ophthalmoscope in front of the patient about 20cm, with +10D lens to check whether the patient's refractive interstitial transparency If the doctor is orthoptotic or has corrective lenses, the refractive power used to see the fundus indicates the refractive condition of the examined eye. Generally, the eye is first made to look straight ahead to examine the optic papilla, then along the retinal vessels to examine the superior and inferior temporal, superior and inferior nasal quadrants, and finally the eye is made to look to the temporal side to examine the macula. The size of the fundus lesion is expressed by the diameter of the optic papilla, and the degree of concavity of the lesion is measured by the refractive index of the lens, which is equivalent to 1mm in 3D. Some examining glasses have a green filter for better observation of the optic nerve fibers and macula.

Indirect otoscope

Indirect otoscope must be fully dilated pupil, in the dark room, the doctor turn on the power, adjust the distance and the position of the reflector, start with a weaker light observation, see the corneal, crystal and vitreous turbidity, and then the light directly into the pupil of the examined eye, and let the examined eye look at the light source, generally with +20D objective lens placed in front of the examined eye 5cm, the convex side of the objective lens to the examiner, the examiner to The objective lens is placed at 5 cm in front of the examined eye, with the convexity of the objective lens facing the examiner, the examiner holds the objective lens in his left hand and fixes it at the orbital rim of the patient, the examined eye, the objective lens and the examiner's head are fixed, when the optic papilla and macula are seen, the LCD Display Digital Chargeable Otoscope Ophthalmoscope Set is moved toward the examiner, and the stereo image of the optic papilla and macula can be clearly seen at 5 cm in front of the examined eye. The inverted image of the optic papilla and macula can be clearly seen at 5cm in front of the examined eye.

Laser Indirect Ophthalmoscope Market Modest Situation Among the Top Manufacturers

Ophthalmoscope examines the interior structure of an eye and are combined with a source of light and lenses, which enables effective examination of interior structures of an eye. Ophthalmoscopes are used to perform ophthalmoscopy, which is regular examination of the eyes. Moreover, various other diseases such as presbyopia, dry eye, cataract, diabetic retinopathy, amblyopia, and others are diagnosed using ophthalmoscopes. In medical practice, ophthalmoscopes are most commonly used on patients who are suspected to have diabetes, hypertension, headaches, head trauma/injury, loss of/degraded vision, and eye pain. Ophthalmoscopes are divided into categories such as direct ophthalmoscopes and indirect ophthalmoscopes. Direct ophthalmoscopes are handheld devices, which are used by physicians to diagnose, whereas indirect ophthalmoscope can be mounted on head by the physician and the lens is held close to the eye. Laser indirect ophthalmoscopes are widely adopted by ophthalmologists, as using laser indirect ophthalmoscopes is convenient than direct ophthalmoscopy.

Technological advancements in ophthalmoscopes is expected to drive laser indirect ophthalmoscope market growth over the forecast period

Manufacturers such as Welch Allyn, Heine Optotechnik GmbH & Co. KG, Iridex Corporation, Keeler Limited, and others offer technologically advanced laser indirect ophthalmoscopes. Laser indirect ophthalmoscopy offer advantages such as wider field of view, better image resolution, less irritation to the ocular surface, and ease in ophthalmic examination, as the ophthalmoscope is mounted on the forehead of the physician/ophthalmologist. Indirect ophthalmoscopes available today facilitate improvements in eye examination results, and care. For instance, Smart LIO offered by Lumenis is a multiwavelength system in the market, and is compatible with multiple Lumenis photo coagulators. Smart LIO supports three wavelengths such as 532 nm (green), 577 nm (yellow), and 659 nm (red). Other technological advancements include adjustable interpupillary distance, adjustable mirrors, portable power packs, dust sealed optics, and others. These factors are expected to drive the global laser indirect ophthalmoscope market growth over the forecast period.

The global laser indirect ophthalmoscope market size was valued at US$ 89.5 million in 2017 and is expected to witness a robust CAGR of 4.2% over the forecast period (2018–2026).

Rising prevalence of certain ophthalmic diseases such as peripheral neovascularization, lattice degeneration, and diabetic retinopathy is driving growth of the market. For instance, according to the Royal National Institute of Blind People (RNIB), over 5.7 million people are suffering from sight-threatening eye conditions in the U.K, in 2014. Moreover, 2 million people were suffering from sight loss in 2016, which is expected to increase to over 2.7 million people by 2030. Moreover, according to the Royal National Institute of Blind People (RNIB), in 2014, around 350,000 people were registered as blind or partially sighted. Increasing healthcare expenditures for treatment of sight loss, blindness, and sight-threatening conditions are expected to propel demand for basic eye care and examination, thereby propelling demand for necessary equipment such as laser indirect ophthalmoscopes over the forecast period. According to the RNIB- Eye Health 2016 report, in the U.K., during 2016, sight loss, blindness, and sight-threatening conditions accounted for US$ 2.03 million, US$ 0.27 million, and US$ 5.7 million healthcare expenditures, respectively.

However, product recalls are expected to restrain the global laser indirect ophthalmoscope market growth over the forecast period. For instance, in February 2018, Iridex Corporation voluntarily recalled TruFocus LIO Premiere Laser Indirect Ophthalmoscope, as three adverse events occurred during procedures in which the TruFocus LIO Premiere was used.

Some of the major players operating in the global laser indirect ophthalmoscope market include Ellex Medical Lasers Ltd, Iridex Corporation, Alcon, Carl Zeiss Meditec AG, Lumenis Ltd., Topcon Medical Laser System, Nidek Co. Inc., Ziemer Ophthalmic Systems AG, Heine Optotechnik GmbH, and Keeler Ltd.
