Retinal conditionsAge-related macular degeneration, macular puckering, macular hole or vitreous detachment, retinal tears and retinal detachment - Orton's ophthalmologists will help you.
Age-related macular degeneration
Age-related macular degeneration, or ARMD, affects the macula – the area responsible for high-acuity vision at the back of the eye. There are two types of ARMD: dry and wet. Both types result in impaired visual acuity in the central visual field. The wet type of ARMD also causes distorted vision. The dry type of ARMD is far more common and often progresses very slowly. There is no treatment for this type as such. A varied diet rich in fruit and vegetables and avoiding smoking may delay the progression of dry ARMD. Wet ARMD is associated with macular swelling and bleeding. Visual impairment may progress quite rapidly. Wet ARMD is treated by injecting medication into the eye. The treatment is most effective in the early stages of the condition, and it is therefore important to have your eyes examined early enough by an ophthalmologist.
Diabetes may cause changes in blood vessels at the back of the eye. If untreated, these may result in loss of vision. Some of these changes may cause no symptoms for a lengthy period of time. It is therefore essential to monitor the back of the eye – the fundus – by fundus photography to identify any changes early and treat them in time. Treatments involve laser photocoagulation of the fundus, medicine injections into the eye, and vitreous and retinal surgery as required.
In some situations, an extra connective tissue membrane – a macular pucker – may develop on the inside of the retina in the area responsible for high-acuity vision. The pucker may start pulling and creasing the retina, which impairs and distorts central vision. The treatment involves an ocular surgery procedure in which the pucker is peeled off the retina. Once the pucker is peeled off, the patient’s vision may be gradually restored.
The posterior vitreous membrane may pull on the middle of the macula – the area of high-acuity vision. This may cause a tear in the retina. The resulting macular hole causes loss of ‘straight-ahead’ vision; while reading, for example, you may feel the letters are jumping up and down. A macular hole can almost always be closed with surgery, which typically also improves vision.
Vitreous detachment, retinal tears and retinal detachment
Tears or holes may form in the retina. In the majority of cases, these are caused by vitreous detachment, a condition in which the posterior vitreous membrane (which coats the vitreous jelly on the inside of the eye) is detached from the back of the eye. Vitreous detachment generally occurs at about the age of 60 to 70 but may sometimes occur at a younger age. Symptoms include dots, floaters or “mosquitoes” that dance in your visual field as you move your eyes. Sometimes, there may also be flashes of light resembling a lightning flash. Vitreous detachment is usually harmless. It does not require treatment as such. To exclude any tears, however, it is a good idea to have your eyes checked by an ophthalmologist, preferably within a week after the symptoms develop.
Tears are often associated with flashing lights in the visual field. They may sometimes also involve bleeding inside the eye, which manifests as a shower of black dots. The tear allows fluid to pass under the retina, which results in retinal detachment. The detachment shows as a black shadow that progresses in the visual field over hours or days. The moving spots also considerably decrease over a few weeks. Tears can be limited with laser photocoagulation to prevent actual detachment. Retinal detachment requires urgent surgery.
Retinal blood vessel occlusion, inflammatory changes, hereditary degeneration and other changes also often manifest as impaired or distorted vision or as defects and shadows in the visual field.

Glaucoma is a group of diseases involving progressive damage to the optic nerve head at the back of the eye. In persons with glaucoma. The damage generally progresses slowly and gradually narrows down the field of vision. Your doctor will assess which treatment is most suitable for you.
Cataracts are the most common surgically treatable eye disorder in older people. Modern ultrasound-assisted cataract microsurgery is a common and safe procedure. New technology has also vastly improved the outcomes and accuracy of surgery.
Hygiene standards at Orton are very strict, including hand hygiene by staff members. Particular attention is given to the hygienic properties of the devices, equipment and materials we use in patient care.
The cornea is the clear outermost layer of the eye. Dryness of the eye is the most common condition of the cornea and tear film. Our experienced surgeons are familiar with all the specialised techniques related to corneal conditions.
Orton’s ophthalmological services were established to meet the challenges of modern eye care and eye surgery. Our first and foremost aim is to ensure the best possible functional vision and outcomes after eye surgery.
The term uveitis refers to inflammation within the eye. The acute symptoms of iritis involve increased sensitivity to light and eye pain. Orton’s eye surgeons are highly skilled in the treatment and follow-up of uveitis, and have long experience in the treatment of uveitis-related cataracts and glaucoma.
