The development and treatment of V-pattern and upshoot in adduction in cyclic esotropia
Published in Jan-Tjeerd de Faber, 28th European Strabismological Association Meeting, 2020

RESULTS: All patients developed a V-pattern and upshoot in adduction. After strabismus surgery, normal eye alignment with some signs of binocularity was reached in all three patients. Moreover, the V-pattern and upshoot in adduction completely resolved.

A complete ophthalmology examination is necessary prior to the procedure. This includes evaluation of the degree of proptosis, assessment of eye movements and diplopia, measurement of visual acuity, and colour vision. Pre-operative consent must include discussion of risks including permanent double vision and need for strabismus surgery.
Ophthalmology

There is a very close relationship between visual function and ocular alignment in children, and many children with squint develop amblyopia. Conservative management: detection and treatment of refractive errors (spectacles) and amblyopia (occlusion therapy of the ‘good eye’) are important.Surgical treatment: ocular realignment by means of strabismus surgery can then be carried out if necessary.Retinoblastoma may be treated by chemoreduction and focal therapy (laser photocoagulation and cryotherapy). In some cases, external beam radiotherapy is also needed. Unfortunately, many eyes with advanced disease need to be enucleated.

A total of 64 patients (34 males and 30 females) with CP and strabismus were included in our study. The mean age at strabismus surgery was 3.1 years and the mean follow-up was 6.0 years (range 6 months to 8 years). The strabismus patterns in our patients were infantile exotropia in 36 patients (24 mild and 12 severe) and infantile esotropia in 28 patients (16 mild and 12 severe) (Figure 1). Refractive errors included myopia (11/40 patients in mild cases and 10/24 in severe), emmetropia (4/40 in mild and 2/24 in severe), and hyperopia (25/40 in mild and 12/24 in severe). Deficits in binocular fusion were prevalent with 20/40 of mild cases with absent fusion and 16/24 of those with severe CP. Amblyopia was also prevalent in our cohort with 25/40 of mild cases showing amblyopia and 13/24 of severe cases. Nystagmus was also evaluated and found to be present in 10/40 with mild disease and 7/24 of those with severe disease. The presence of nystagmus did not influence the success rate.
Influence of one or two horizontal muscle surgeries on OCT findings

It has been reported that macular or retinal thickness increases after cataract surgery.7 The peripapillary retinal nerve fiber layer (RNFL) has also been shown to increase after cataract surgery, as determined with both SD-OCT8 and with scanning laser polarimetry.9 Strabismus surgery is a frequently performed ophthalmologic operation and may cause structural and functional changes in the eye. In previous studies, following strabismus surgery, ocular blood flow and anterior chamber volume changes, cystoid macular edema, and intraocular pressure changes due to postoperative axial length changes have been reported.10,11 Only a small number of published studies have examined the effects of strabismus and strabismus surgery on the macula and choroid, and their results vary.12–16 Although there are publications in the literature examining the effects of strabismus, amblyopia, and intraocular surgeries such as cataract surgery on the RNFL, no study to date has investigated the effect of strabismus surgery on the RNFL thickness.17,18
Complications of Limbal Stay Sutures in Strabismus Surgery

An awareness of these potentially vision-threatening complications has led the authors to always include the specific mention of vision loss as a complication of strabismus surgery during the consent process. However, complications due to limbal stay sutures can be easily avoided by using alternate methods of globe traction. One method is to use locking forcepsfor example, Moody Curved Fixation Forceps (Storz Ophthalmic instruments). This is the method of globe traction preferred by the authors. If the surgeon prefers stay sutures, one can consider placement of the sutures immediately peripheral to the limbus and avoiding the cornea. The choice of suture may also be relevant in preventing complications. It is recognized that monofilament sutures have less surface area than polyfilament sutures, hence less chance of bacterial colonization,8 although this is more relevant in sutures that remain in the wound. Furthermore, monofilament sutures produce less friction and thus less tissue drag.8 Thus, use of monofilament sutures may be favored over the use of polyfilament sutures as we hypothesize that the chances of epithelial cells being dragged into and implanted in the stroma may be higher with polyfilament suture usage as in our cases.
