1/31. Clinical features and surgery for acquired progressive esotropia associated with severe myopia.

    PURPOSE: The purpose of this study was to evaluate the clinical and physiological findings and to determine the most appropriate surgical procedure for acquired progressive esotropia with severe myopia. methods: Thirty-eight cases of acquired progressive esotropia with severe myopia were examined to evaluate their clinical and physiological findings. All cases were divided into four groups according to the limitation of their abduction. The eyeball in group IV is fixed in an extremely adducting position. Thirty-one cases underwent strabismus surgery; medial rectus muscle recession and lateral rectus muscle resection in 23 cases, transposition of superior and inferior rectus muscles (modified Jensen procedure included) in eight cases. RESULTS: The medial rectus muscle recession with the lateral rectus muscle resection procedure was effective in the early stage of acquired progressive esotropia patients. Transposition procedure was effective in the severe abducting limited patients. CONCLUSIONS: As the recession & resection procedure is easier than the transposition procedure, we recommend performing surgery in the earlier stage of the abducting disorder before the eyeball is fixed in an extremely adducting position.

2/31. Decompensated strabismus after laser in situ keratomileusis.

    We present a case of decompensated nerve IV palsy with vertical diplopia afer bilateral laser in situ keratomileusis. As the patient was given monovision, we believe diplopia occurred with a decrease in vision in 1 eye and interruption of fusion. Although corrective spectacles to restore equal vision at distance were prescribes, the patient needed a prism to eliminate her double vision. We suggest a careful cover/uncover test and versions assessment in all candidates for refractive surgery who want monovision correction and a full ocular motility evaluation if there is any doubt about binocular issues.

3/31. Ocular deviation after unilateral laser in situ keratomileusis.

    Laser keratomileusis and excimer laser photorefractive keratectomy in situ are widely used therapies for treating myopia. The corrections of refractive error by glasses or contact lens result in a relatively equal refractive correction on both eyes. However, refractive surgery on a single eye can cause a focus disparity between both eyes and may result in the impairment of fusion leading to strabismus. This article aims to report a case where diplopia and esotropia occurred 1 month after laser keratomileusis (LASIK) in situ for the correction of myopia.

4/31. diplopia as a complication of laser in situ keratomileusis surgery.

    A case is presented of a patient with high myopia who developed vertical binocular diplopia after decentred laser in situ keratomileusis (LASIK) surgery with associated decompensation of pre-existing exophoria into an exotropia. A 40-year-old man underwent LASIK surgery for high myopia in his right eye. Preoperatively, he was approximately -26.00/-2.00 x 35 degrees with visual acuity of 6/12(-2) in that eye. He also had an asymptomatic exophoria. After LASIK surgery, he achieved a refraction of -3.25/-0.50 x 80 degrees with 6/21 best-corrected visual acuity. He also developed binocular diplopia. The ablation zone had been decentred upwards and there was also an exo- and hypo-deviation of his right eye. He was able to superimpose the two images in free space with vertical and horizontal prisms.A hard contact lens also resulted in superimposition of the two images.Vertical decentration of the ablation zone can induce a vertical prism effect after LASIK surgery and result in vertical diplopia. This together with abnormal optics also caused loss of best-corrected vision and decompensation of his pre-existing exophoria into an exotropia.

5/31. Bilateral recession-resection surgery for convergent strabismus fixus associated with high myopia.

    The authors report two patients with more than 20 diopters of myopia, severely restricted abduction, and more than 90Delta of acquired esotropia. Marked axial elongation of the globes was present. Each underwent large bilateral medial rectus recessions and bilateral lateral rectus resections. The deviations were significantly reduced and abduction improved with combined horizontal recession-resection surgery on both eyes.

6/31. Refractive surgery for refractive errors which cause strabismus. A report of 8 cases.

    PURPOSE: While excimer laser refractive surgery is a well known procedure for correcting refractive errors, its use in adult patients with accommodative or partially accommodative esotropia who wish to remove their glasses, and those with high anisometropia and exotropia has not been extensively studied. We report our experience treating these two conditions with refractive surgery. methods: A retrospective review of the records of 8 adult patients with stable refractive error who underwent refractive surgery by the LASIK procedure. Three patients had accommodative esotropia, 3 had partially accommodative esotropia, and two patients had myopic anisometropia and exotropia. RESULTS: The LASIK refractive treatment corrected the strabismic deviation related to the hyperopia in the accommodative and partially accommodative esotropic patients. It also corrected the exotropia in the myopic anisometropic patients with exotropia. CONCLUSIONS: Refractive surgery is effective in treating accommodative and partially accommodative esotropia in adults and in cases of myopic anisometropia with exotropia.

7/31. Bilateral cataract and high myopia in a child with trichothiodystrophy: a case report.

    Trichothiodystrophy refers to a group of autosomal recessive disorders that have in common brittle sulphur-deficient hair (7). The abnormalities are usually obvious at birth and the clinical expression is variable. Ocular abnormalities are common with bilateral cataract being the most frequent one. We report on a four year old boy with trichothiodystrophy (complementation group TTD-A) who presented to us with strabismus, high myopia and bilateral cataract.

8/31. Myopic strabismus fixus: a mitochondrial myopathy?

    PURPOSE: Ultrastructural analysis of extraocular muscle in a case of myopic strabismus fixus. DESIGN: Interventional case report. methods: Incisional biopsy and ultrastuctural analysis of recti muscles in a female patient with myopic strabismus fixus. RESULTS: Ultrastuctural analysis revealed evidence of mitochondrial myopathy. CONCLUSION: Acquired strabismus fixus due to high myopia may be a manifestation of mitochondrial myopathy, a finding that has not been previously reported.

9/31. Exodeviation following monocular myopic regression after laser in situ keratomileusis.

    We report a 44-year-old woman with intermittent left exotropia of 35 prism diopters at distance who initially exhibited alignment of both eyes after bilateral laser in situ keratomileusis (LASIK). The exophoria was not preserved due to myopic regression in the dominant eye. An uneventful LASIK treatment was performed to correct -11.00 -0.50 x 130 in the right eye and -13.50 -1.50 x 145 in the left eye. The aim was to achieve emmetropia in both eyes. Although an examination revealed exophoria at near and distance during the 6 months following refractive surgery, the tropic aspect of the divergent deviation appeared in the right eye following the myopic regression. Laser in situ keratomileusis is an effective option to achieve binocular visual quality in myopic anisometropic patients. However, myopic regression after LASIK may disrupt the binocular visual quality.

10/31. Binocular vision impairment after refractive surgery.

    PURPOSE: To illustrate the need for an accurate preoperative orthoptic examination to prevent postoperative changes in binocular vision. SETTING: Department of ophthalmology, University Hospital Antwerp, Edegem, belgium. methods: Five patients presenting major subjective complaints after refractive surgery were analyzed. RESULTS: In 1 patient, a latent N IV palsy decompensated after laser in situ keratomileusis (LASIK) in the more myopic eye to achieve monovision. A second patient, operated on for N IV palsy 10 years earlier, presented a recurrence of the palsy after bilateral LASIK for myopia. The third patient complained of discomfort in binocular vision caused by aggravation of a preexisting intermittent esotropia that worsened after LASIK for hyperopia. The fourth patient complained of diplopia after LASIK in the highly anisometropic and exotropic eye. The fifth patient experienced a decrease in fusion and stereopsis at the time he became anisometropic after bilateral LASIK. CONCLUSIONS: Special care should be taken of patients who have a preoperative history of strabismus surgery, an overcorrection or undercorrection in 1 or both eyes, or anisometropia and of those who are unhappy with contact lenses. An orthoptic examination should be done with and without spectacle correction to detect underlying vertical phorias. Intended monovision should be examined initially using contact lenses.
