Our laboratory is fitted with top quality medical equipment suited for diagnostics and treatment of the posterior segment of the eye.
- Fluorescein angiography capable of taking a series of pictures with a digital camera
- OCT – optical coherence tomography
- Ophthalmic ultrasound with A-scan, B-scan probes, and UBM
- Laser GYC 1000
This examines the functional state and tightness of retinal vessels. It is especially recommended in the case of age-related macular degeneration (AMD) and diabetes, which damages small blood vessels. The examination is preceded by consultation with an ophthalmologist or anaesthesiologist and a thorough medical history. Following a pharmacological dilation of the pupils and insertion of a needle, the patient sits comfortably in front of a special camera – an apparatus equipped with suitable filters to watch the fluorescent dye in blood vessels. During the examination a contrast, fluorescein, is introduced intravenously and then a series of photos of the fundus of the eye taken several seconds apart is conducted. The patient needs to closely follow doctor’s orders and be maximally focused. The examination may be repeated many times in patients of all ages. Due to dye concentration, the skin, conjunctivae, faeces, urine and mucous membranes will appear yellow after the examination, which usually gradually disappears after max. 36 hours. After angiography the patient receives the results, which include photos and descriptions with further treatment recommendations. Often the examination is decisive for the diagnosis and proper treatment.
Optical coherence tomography has recently become one of the basic and frequently irreplaceable diagnostic techniques in ophthalmology. It is an innovative, non-invasive and painless method of retinal disease diagnostics. However, it requires transparent optical media. The method allows tissue section analysis to be conducted, three-dimensional images to be obtained and maps of separate retina layers to be created, which will reveal the smallest lesions in the retina. OCT is able to measure retina thickness, nerve fibres within the optic disc, i.e. to monitor glaucoma lesions, and analyse the optic disc. Indications for the examination include:
- age-related macular degeneration – AMD
- macular oedema
- macular foramen
- pre-retinal membranes
- diabetic maculopathy
- glaucoma monitoring
The examination allows ultrasonic imaging of ocular structures. It is a non-invasive, repetitive method, which allows diagnostics and monitoring of certain diseases of the posterior segment of the eye in the case of non-transparent optical media. Indications: diagnostics of retinal detachment, intraocular tumours, foreign bodies, exudative-haemorrhagic lesions, changes in the course of diabetes, haemorrhages and inflammations of the posterior segment of the eye. With the patient’s eyes closed, following the application of gel onto the lids, the doctor uses the probe to present the examined structures on the monitor.
Corneal endothelium examination using endothelial microscope
The endothelium performs numerous important functions essential for the proper functioning of the cornea; therefore, its examination is key to the diagnostics of the eyeball. One of the most prominent features of endothelium cells is that they do not reproduce, instead they decrease in number with age, due to surgical procedures or contact lenses. The technique is totally painfree and allows a series of electronic images of endothelium tissue to be obtained, which after an automatic analysis show clinical biological parameters of endothelium cells: number, density, shape, area. The tool is indispensable in the examination of the cornea’s condition.
What is vitrectomy?
Vitrectomy is microsurgery to remove the vitreous humour, most often to allow access to retinal lesions.
During the surgery, three small incisions of the sclerotic coat are performed, or sclerotomies, which allow surgical tools to be inserted into the eyeball.
Most common indications for vitrectomy include:
- vitreous haemorrhage
- retinal detachment
- pre-retinal membranes
- macular foramen
- proliferative vitreoretinopathy
- intraocular foreign body
- floating lens fragments
- intraocular inflammation
Following vitrectomy, depending on the cause of surgery and topical eye condition, the eyeball is filled with:
- aseptic fluid,
- filtered air,
- expanding gas usually indicated in cases requiring a prolonged tamponade; adding a gas may require maintaining a certain position e.g. lowered head or lying in a special way,
- or silicone oil with low molecular weight.
Recommendations for post-vitrectomy patients:
- The operative wound is healing, which will take c. 1–2 months. During the healing period, one can experience a „foreign body”, sensation underneath the lid. The feeling will slowly retreat.
- Keep your lifestyle healthy and energy-limiting. During the postoperative period, refrain from certain activities, physical exercise in particular.
- If the vision is worse or pain occurs, immediately contact the centre.
- Do not practise sport in the postoperative period.
- Do not press or rub the eye.
- Follow instructions for the application of drops. If the drops run out earlier than the set follow-up visit, contact an ophthalmologist for a new prescription.
- Wash your hands thoroughly before applying the drops.
- How to apply the drops
– pull the lower eyelid down and roll your eyes toward the top of your head: administer one drop without touching the lid, eyelashes or any other objects with the dispenser; close they eye for ca. one minute; do not use eye drops if they have been opened for > 2 months
- Vision acuity after vitrectomy will be gradually improving over the course of c. 6 months; therefore, no change of lenses is recommended during the first year after surgery.
- In the case of gas bubble injection into the eyeball during vitrectomy, it is compulsory to place your head in an appropriate position for c. 7 days after the surgery (head positioning will be discussed with you by the ophthalmologist).
- Until the gas bubble is fully absorbed, the patient cannot travel by plane.
