What are the common problems of adult strabismus?

  In our clinical work, we often find that some patients only know that strabismus is curable when they receive treatment, and some patients come to receive treatment only after their relatives and friends are cured and are introduced to them, although they always knew they had strabismus before, but because they know little about this disease, they are afraid to receive medical treatment. The common problems of adult strabismus patients are.  Is adult strabismus (squint) treatable?  Yes. Some of the methods used to treat childhood strabismus can also treat adult strabismus. Treatment may include trigeminal lenses and surgery. Most adults with strabismus can have successful surgical correction.  Why does strabismus occur in adults?  Strabismus in adults can be either a remnant of childhood strabismus or it can be acquired in adulthood. A new strabismus in an adult can be caused by a systemic disease such as a stroke or tumor, but in most cases, there is no clear cause.  Is all adult strabismus correction cosmetic?  No. Adult eye position correction surgery is performed for several reasons. Adults are often disabled by diplopia that occurs as a result of strabismus. Trigonometry or surgery will improve diplopia and stereopsis. Also, strabismus affects adults emotionally, socially, and financially. Correcting the eye position can “rebuild” the appearance of the eye position and provide a better quality of life.  Are there risks associated with adult ophthalmic surgery?  Every surgery carries some risk. For strabismus surgery, the most common risks are residual strabismus and diplopia. Most diplopia after strabismus surgery is temporary; however, individual diplopia may also persist and not subside. Fortunately, more serious risks are extremely rare. Systemic health risks vary depending on individual health status, and we routinely operate under supervised anesthesia combined with local anesthesia rather than general anesthesia to avoid the risk of systemic accidents.  What is the success rate of extraocular muscle surgery?  Most patients will experience significant improvement in eye position after a single surgery. Occasionally, the surgery is only partially successful, or a period of time may pass before the eye position changes after strabismus surgery. A very small number of patients may require a second surgery or a trigeminal lens. Our clinical use of supervised anesthesia combined with local anesthesia for strabismus correction allows us to do intraoperative suture adjustments, greatly improving the success rate of a single surgery.  How painful is this type of surgery?  We have done a comparison of pain scores for strabismus patients and found that most of the pain scores during strabismus surgery are 1-3 (total score of 10), which are within the range of being able to cooperate with the surgery. Many patients report that there is some eye swelling and pressure on the eyeball during the surgery, but there is no other special pain. The discomfort after eye muscle surgery is usually not severe. Headache, pulling sensation when the eye is turned and foreign body sensation in the eye are the most common complaints. These symptoms usually last only a day or two and resolve on their own. Because of the supervised anesthesia, some sedative and pain medications are given intravenously and may cause some dizziness and nausea after the procedure, which usually last for a few hours and then gradually resolve. Sensitive patients can take oral pain medication, which usually reduces discomfort. Most patients recover completely in a few days. Some patients limit swimming and heavy physical activity until a few weeks after surgery. We generally just ask patients to be careful not to get any water in their eyes for a short time after surgery.  Does strabismus surgery require hospitalization? How will it affect my daily life?  Although the need for hospitalization varies depending on general health and patient preference, surgery to correct eye position is usually an outpatient procedure. We usually arrange for patients to come in the same day, operate the same day, go home after surgery, or rest overnight and be discharged the next morning with medication. This arrangement also facilitates the anesthesiologist to help us with supervised anesthesia. After surgery, most patients resume all normal activities within a few days.  At what age is it “too old” to have strabismus surgery?  Eye position can be corrected at any age, and surgery should be considered as a treatment if correcting the eye position is likely to improve symptoms or improve quality of life. We have had patients in their 70’s and 80’s, and some of our senior patients are more interested in getting a wish they have had for years.  I felt embarrassed to look directly at the person across from me because of my skewed eye position. For me, people were always confused by my wandering eyes, which caused social interaction problems and made it difficult to get a job that I wanted. Is this really because of strabismus? Yes, it is. Recent studies have confirmed these observations. Eye strabismus can impede social interaction, confidence and employment opportunities. Everyone deserves to have an eye position if possible. With socioeconomic development, strabismus is becoming more recognized by patients and families, and treatment is on the agenda. In general, adult strabismus is a treatable condition and surgery is relatively safe.
