Ophthalmology Seeing Straight
Now Bateeilee blog will post Ophthalmology Seeing Straight, If both eyes do not point in the same direction, you're probably
squint. Inward-turning eyes, called a convergent squint or "cross
eyes", usually occur in young children. A divergent squint, when the
eyes turn outwards is less common. Although not necessarily painful, a
squint can be a distressing condition. Many adults are concerned about
their cosmetic appearance, and nearly four in every 100 adults suffer
from some form of squint.
They may wish to correct this from a cosmetic angle, but there is also the physical disability that often accompanies this condition; loss of eye-hand coordination; bumping into things when ascending, or descending stairs or kerbs; crossing the street, driving, and playing sports.
Many adults who suffer from squint problems are not aware that help is at hand. The good news is that adults need not suffer. Recently there has been an increase in effective, available treatment.
The principal treatments used are Botulinum Toxin and/or eye muscle surgery. Botox has become 'the injection du jour' as more and more people follow in the footsteps of celebrities to smooth out their wrinkles. However, few people realize that the medical use of Botox was originally for the treatment of eyes that were squint. Today, a simple injection can rectify many unsightly turns of the eyes. This is an outpatient procedure that requires only a few drops of anaesthesia, and takes about 30 seconds. "Botox treatment has made a real difference for many patients. Not only does it help to realign the eyes, it can increase confidence and social skills. It's not just a cosmetic thing, it can affect your job prospects," says Mr Christopher Bentley, a consultant ophthalmologist.
But is Botox safe?
According to the surgeons who carry out these 'squint' treatments, Botox has become the treatment of choice for muscular spasms affecting the face; and repeated studies have demonstrated that it is effective and safe. The target muscle is injected with a very fine needle. Benefits begin in one to 14 days after the treatment, and can last on average about three to four months, after which you can go for a top up. All effects of the toxin ultimately reverse with time.
A range of studies have confirmed the side effects to be minor in the vast majority of applications, and they are definitely dose related. The Botulinum Toxin administered in the case of squint treatments is heavily diluted. Some of the reported side effects have included flu-like symptoms, pain at the site of injection, headaches, and muscle weakness, but these are usually mild and transient.
In addition, adjustable stitches are used for squint surgery in adults. The operation is usually done under general anaesthesia and some stitches are not permanently tied. If the squint is still present after surgery, local anaesthetic drops are given and the stitches adjusted until the eyes are in the correct position. "This is a relatively new development and a really helpful tool to help the surgeon to fine tune surgery," says Bentley.
The type and amount of surgery to perform for a particular squint demands an accurate preoperative decision and necessitates meticulous surgical planning and accurate prediction of surgical outcome. "The surgical aims are realignment of the eye muscles where necessary to achieve satisfactory function and appearance," says Bentley.
