Strabismus Department


The strabismus department has an inpatient ward, three outpatient clinics, two operating rooms, a neuro-ophthalmology clinic, and pre-assessment clinic plus Orthoptic and Optometry clinics. The clinics have most modern devices to examination of strabismic patients. A specialist multi-disciplinary team (experienced strabismus surgeons, neuro-ophthalmologists, nurses and optometrists) supports the department.



Strabismus, also called eye deviation, is a condition in which the eyes do not properly align with each other when looking at an object. It is particularly common in young children, but may occur at any age. It can happen due to refractive errors, muscle dysfunction, neurologic disorders, trauma, infection, and idiopathic. Types include esotropia, eyes turn inward; exotropia, outword eye deviation; and hypertropia, vertically misaligned eye. The condition can be manifest or latent. If strabismus presents at early childhood, it can result in amblyopia or loss of depth perception. If it occurs during adulthood, it may result in diplopia. Ocular examination can detect the disease and its impact on vision. Depending on the type of strabismus and its underlying causes, an appropriate treatment is usually required to correct the condition. The main treatments for a patient with strabismus are the following:

  1. Glasses
  2. Especial ocular exercise and ocular occlusion
  3. Botulinum toxin injection into the extraocular muscles
  4. Strabismus surgery on the extraocular muscles



Amblyopia is a decreased vision in an eye that otherwise typically appears normal. It is the most common cause of decreased vision in a single eye among children and younger adults. Any condition that interferes with focusing during early childhood can result in amblyopia. Main causes of amblyopia are strabismus, refractive errors, and deprivation of vision early in life by vision-obstructing disorders such as congenital cataract. Treatment in adulthood may not be effective, and early detection improves treatment success; therefore, diagnosis and treatment of amblyopia as early as possible is necessary. Amblyopia in children without other ocular diseases can be difficult to be detected. As a result, screening for amblyopia is recommended in children between the ages of three to five. Treatments include glasses, ocular patching, and or penalization techniques.


Information for the Patients

All strabismus patients take a primary visit at the outpatient clinics. Most patients can be managed by nonsurgical options, but some of them need surgical treatments. The patients who are scheduled for strabismus surgery must take some precautions before the operation.

Please inform your surgeon or nurses if you have any medical illnesses and history of medical or food allergies; and if you are taking any drugs or herbs that increase risk of bleeding (e.g. warfarin, aspirin, clopidogrel, or heparin).

Please pay attention to the fasting guidelines that are given by clinics nurses.

After surgery, the following considerations are taken:

  • The eye may or may not be patched.
  • The eyes may have some blood in the tear and may be crusted together at the morning next day post-opration.
  • In addition, eye redness may last for a few weeks and ocular discomfort is probable for several days after the operation. 
  • Topical antibiotics and corticosteroid are usually prescribed for several days post-operation.
  • The patients may experience double vision in the first few weeks; it usually improves in most of the cases.
  • The patients should avoid swimming and ocular rubbing for at least two weeks after the operation.
  • The first follow-up date will be on day one to seven after the operation (that will be scheduled according to the type of surgery).

The strabismus patients may require one or more surgery to achieve a desired ocular alignment. In most of the patients, ocular alignment remains stable for a long term but it may change in some cases. In these cases, future surgery may be required.
