Clinica London’s Eye Diagnostic & Orthoptic Centre (ClinicaDOC) is recognised nationally and internationally as being in the vanguard for the assessment of:
The Clinica London Eye Diagnostic and Orthoptic Centre (ClinicaDOC) in central London´s Harley Street Medical Area is the diagnostic hub to go to for all eye diagnostic imaging testing using advanced technology, and for orthoptic and motility assessment, for adults and children.
ClinicaDOC has the most advanced Eye Diagnostic technology and is a vanguard eye motility centre with 5 Orthoptists skilled in assessing visual fields, eye motility, vision in children, binocular vision assessment, accommodative and convergence issues.
ClinicaDOC provides Diagnostic Eye Specialty and Orthoptic Motility testing where we do a wide range of diagnostic imaging and motility tests which are performed by the ophthalmic nurses, technicians and orthoptists.
Clinica London’s Eye Diagnostics and Orthoptic Centre – ClinicaDOC – caters for cataract, cornea, glaucoma, macula disease, neuro-ophthalmlogy, paediatric ophthalmology, retinal disease, strabismus, and uveitis in children and adults.
We are pleased to promote our retinal and choroidal angiography service with fundus fluorescein angiography (FFA) and indocyanine green angiography (ICGA) using Heidelberg SPECTRALIS OCT (Ocular Coherence Tomography).
We are delighted to have the highly specialised module for FFA and ICG on the Heidelberg SPECTRALIS OCT used to look at the retinal and choroidal blood flow in diabetic maculopathy, AMD (Age related macular degeneration), macular oedema, CCR (central serous retinopathy) and many other retinal, macular and choroidal pathologies affecting central vision.
FFA and ICGA are also used for optic nerve pathology diagnosis in neuro-ophthalmology.
Our corneal and ocular surface testing using Pachymetry and with the Pentacam corneal mapping, to show the thickness and shape of the cornea, the angle of the anterior eye, for instance in keratoconus, other corneal diseases such as those awaiting corneal graft, and in glaucoma.
Our excellent orthoptists do Goldman visual fields for older patients and other patients with established eye pathology wishing to continue driving. On request from DVLA (Driver Vehicle Licencing Authority).
The Eye Diagnostics of ClinicaDOC are for all healthcare professionals to refer their patients, as well as for Clinica London patients. It is service used by our Clinica London consultants and an accessible service for outside ophthalmic consultants, optometrists, allied healthcare professionals, and other organisations, to assist for clinical or medicolegal reasons.
A patient may attend ClinicaDOC and / or Orthoptic motility testing and fields done on request from the following:
A patient may also request the tests themselves, for instance if they have a family history of glaucoma or age-related macular degeneration (AMD) or require specific tests for occupational or professional reasons such as visual fields.
Their requirements can be discussed with the team as it may be best if they see one of our Consultants unless they are already under the care of an outside Ophthalmologist or other healthcare professional advising them on their vision.
It is important that the results of tests are discussed with a professional eye care person and fully understood by the patient. For instance, if the patient is having vision screening for cataract, glaucoma, keratoconus or age-related macular degeneration (AMD), ideally, they should see the Clinica London Consultant if they are an independent self-referral.
To detect refractive errors, strabismus, and amblyopia.
Although the Orthoptist can do this alone in order, depending on the circumstances we may well recommend that the child also sees the paediatric Ophthalmologist at Clinica London if they are not already under the care and supervision of an outside Paediatric Ophthalmologist or other healthcare professional.
ClinicaDOC plays a pivotal role in providing comprehensive eye diagnostics and Orthoptic Motility Assessment in Adults and Children for other ophthalmologists, physicians, optometrists and organisations.
Many eye conditions benefit for diagnostic eye screening using scanning laser ophthalmoscopy (SLO) and ocular coherence tomography (OCT) including:
In children, the early detection of refractive errors, strabismus (squint) and lazy eye (amblyopia) by the Orthoptists is important screening in the under 5s age group.
ClinicaDOC is a premier diagnostic hub, offering top-notch diagnostic services to both internal and external patients.
The orthoptists at ClinicaDOC provide specialized diagnostics and can provide additional comprehensive eye care for patients.
ClinicaDOC caters for all ages as appropriate. The orthoptic centre is very active in the assessment of children and teenagers with strabismus, amblyopia, accommodative, refractive issues and lazy eye, and for adults with motility problems as a result of stroke or previous strabismus.
Clinica London is in the vanguard, it is a leader in eye diagnostics and orthoptics, offering comprehensive, high-quality services that meet the needs of both patients and healthcare providers. This focus on diagnostics and orthoptic assessments enhances patient care and contributes a service to optometrists and other medical professionals alike.
Here is detailed information about the specific diagnostic tests, the machines used and their significance in eye diagnostics. These machines are in addition to the general small eye tests of Visual Acuity and intraocular pressure (tonometry). As well as measuring visual acuity using the Thompson screen and measuring the eye pressure with the iCare tonometer, we do tear osmolarity analysis, focimetry to measure the glasses being worn by the patient, autorefraction to measure the refractive error and gauge the glasses needed by the patient to correct this.
The Humphrey Visual Field Analyzer (HFA) is a cornerstone in visual field testing, widely used for detecting and monitoring glaucoma and other optic nerve diseases. This machine measures the visual field of the patient, providing detailed maps that help ophthalmologists assess the extent of vision loss.
The Humphrey visual field test measures the entire area of peripheral vision that can be seen while the eye is focused on a central point. During this test, lights of varying intensities appear in different parts of the visual field while the patient’s eye is focused on a certain spot. Most commonly one eye is tested at a time.
The Humphrey Visual Field Analysis test takes between 15 and 20 minutes to perform.
Key benefits include:
Goldman perimetry is a manual method of measuring the visual field. It is particularly useful for patients who may have difficulty with automated perimetry.
This exam is usually used to detect brain or nerve (neurologic) problems and to detect the extent of the visual fields and whether they meet current driving standards. Goldman fields take about 20 minutes to perform and are done by the Orthoptists.
Key benefits include:
Optical Coherence Tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-sectional pictures of the retina, macula, optic nerve head, cornea and anterior segment.
OCT is a 3-D scan of the back or the eye, the optic nerve, the iris or cornea. It looks at layers, or a cross section of cells. OCT is relevant to Retina, Glaucoma and Cataract, Anterior Segment and Neuro-Ophthalmology.
We use the SPECTRALIS® modular system which has different lenses for the different modalities.
OCT is an outpatient test which takes 15 minutes with the patient sitting comfortably in front of the OCT with their chin on the chin rest and looking at the lens at a blue target in the depths of the lens. If Fundus Fluorescein Angiography (FFA) and Indocyanine Green Angiography (ICGA) is required, a full 45 minutes is allocated for the testing.
Very few other units offer these FFA and ICGA tests, nor such a wide range of tests, making ClinicaDOC unique. We are super special.
Test, this is an outpatient test which takes 15 minutes with patient sitting comfortably in front of the OCT with their chin on the chin rest and looking at the lens at a blue target in the depths of the lens. Several images will be taken and if previous test has been done the data can easily be compared with those previous tests and progression charts demonstrated made. A 15-minute appointment is required.
The visual acuity and intraocular pressures are always included with the OCT testing using the Snellen chart and iCare tonometer.
Pachymetry is the measurement of corneal thickness, an important test for diagnosing and managing glaucoma. Thicker or thinner than normal corneas can affect intraocular pressure (IOP) readings. Key benefits include:
Scanning laser ophthalmoscopy and autofluorescence. Clinica London uses the Californian Optos to visualise at least 170 degrees of the retina through an undilated pupil. It provides colour images of the whole of the back of the eye including the optic disc, retinal blood vessels and retina out to the equator and beyond. Autofluorescence views are also available which will show deeper pigmentation and changes within the choroid.
Uses: This provides photographic documentation of the overall appearance of the retina (colour) and of any pigmented lesions and deeper choroid (black and white). It can be used in children from the age of approximately four years upwards and all adults. It does not require pupil dilation, but pupil dilation may be done. It allows a scan of the retina to detect at a glance pathology.
Procedure: This is done as an outpatient procedure and takes 15 minutes just preceded by the visual acuity with the Snellen chart and the intraocular pressure with iCare tonometer. The patient sits comfortably with their chin on the chin rest at a slight angle but looking into the bowl of the machine where they will see a red light changing to a blue light and then a green light. When they see the green light this means that the images will be in focus, and they are asked to stare at that without moving so that the images may be taken. It is a good monitoring device for pathology. This is done as an outpatient procedure 15 minutes.
Key benefits include:
The Pentacam is an advanced device that provides comprehensive analysis of the anterior segment of the eye, including the cornea, iris, and lens.
Key benefits include:
Corneal pachymetry involves measuring the thickness of the cornea by an ophthalmologist or ophthalmic technician using a pachymeter or with Pentacam corneal topography.
Pachymetry is imperative in corrective eye surgeries, including refractive surgery LASIK (laser in situ keratomileusis) on the cornea.
Measuring corneal thickness allows eye surgeons to determine eligibility for certain procedures. It also helps avoid any potential complications.
Pachymetry will also tell your surgeon if you have any inflammation or swelling in your cornea.
For example, people with corneal dystrophy such as Fuch’s Dystrophy may have built-up fluid in their cornea, which can make it swell. Those who wear contact lenses are also prone to swollen corneas which can subsequently cloud vision.
Pachymetry is used in Glaucoma Investigation where specific accuracy is required in the measurement of intra-ocular pressure (IOP). The central corneal thickness can influence the IOP and its interpretation.
A pachymetry test takes less than 5 minutes. If Pentacam corneal mapping (corneal topography) for shape as well is required, allow 15 minutes.
Ocular biometry is a test that measures the dimensions of the eyeball: the axial length (distance between the anterior and posterior parts of the eye) and the depth of the anterior chamber (part between the cornea and the iris and lens).
Biometry measurements are used to check the power and size of lenses in patients about to undergo lens cataract surgery where an intraocular lens will be inserted. Biometry is essential to help define the type and strength of the intra-ocular lens implant that will replace the natural lens. Ocular biometry takes up to 15 minutes to perform.
A-scan and B-scan are two types of ultrasound tests used to examine the eyes. These scans help assess the structure of the eye and can also reveal underlying health conditions like high blood pressure or diabetes.
Ultrasound technology plays a crucial role in eye care, especially for diagnosing eye diseases and planning surgeries, such as cataract surgery.
While both A-scan and B-scan use the same basic ultrasound principles, they serve different purposes and provide distinct types of information:
Both scans are essential tools in ophthalmology for evaluating and treating eye conditions.
Both A-scan and B-scan are safe, painless ultrasound procedures.
Nasal endoscopy is a procedure used to examine the inside of your nasal cavity and the openings to your sinus passages. A practitioner inserts an endoscope—a long, thin tube with a camera and light—into your nose to capture video images, which are displayed on a screen for evaluation.
During the procedure:
The procedure will take up 10 minutes.
Syringing and probing is a procedure used to evaluate the anatomy and function of the lacrimal drainage system (tear ducts). It is a safe and well-tolerated procedure that provides valuable diagnostic information. Additionally, it aids in surgical planning if any blockages or abnormalities are found.
A 2 ml syringe filled with saline solution (a sterile saltwater solution) is attached to a lacrimal cannula. The patient’s head is gently tilted backward, and the cannula, which has a blunt tip, is inserted into the punctum (the small opening in the eyelid) and advanced into the canaliculus (the tear duct).
Saline is then flushed into the canaliculus through the cannula. If the solution drains into the throat, this indicates that the lacrimal drainage system is clear and functioning properly. However, if there is a blockage, the saline will not pass through to the nose and throat. Instead, it will flow back into the eye, confirming the presence of a blockage in the system. The procedure will take up 10 minutes.
These advanced eye diagnostic machines collectively enhance the diagnostic capabilities of the ClinicaDOC service, ensuring comprehensive and accurate assessments for a wide range of eye conditions. By leveraging such advanced technology, Clinica London can provide high-quality care and maintain its position as a leading diagnostic centre.
