Motility and binocularity outcomes in vitrectomy versus scleral buckling in retinal detachment surgery

Abstract

The findings confirm that ocular motility problems are not exclusive to scleral buckling, with the incidence being similar in both groups. Slinging of the extraocular muscles and the accompanying dissection, resulting in the 'fat adherence syndrome', must be considered as contributory factors. The visual deficits which inevitably occur as the result of retinal detachment seem to play a more major role in the disruption of binocularity in these cases.

Strabismus following retinal detachment repair: a comparison between scleral buckling and vitrectomy procedures

“…A total of 48% of our study group comprised of patients who, in contrast to other studies, had undergone PPV detachment repair. Wright et al 11 reported ocular motility problems in a group of PPV patients, where 4 of 17 patients had manifest deviations. In contrast, Fison and Chignell 10 did not find any patients with diplopia after vitrectomy in their series of 125 consecutive cases of vitrectomy patients.…”

“…7 Conflicting reports show that PPV has either no effect on motility or a similar effect to external buckling. 10,11 We conducted a retrospective study of patients treated for persistent diplopia after RD surgery over a 2-year period to ascertain:…”

Effect of scleral buckle removal on strabismus surgery outcomes after retinal detachment repair

“…Since strabismus surgery after scleral buckle placement is an uncommon procedure, it was difficult to analyze a large group of patients from a single institution. Indeed, the largest case series in the literature only included 20, 21 17, 22 and 12 26 cases. Our small sample size limited the power of our study.…”

The effect of scleral exoplant removal on strabismus following retinal detachment repair

“…3,7,8,11,12 Restrictive fibrosis has been observed during strabismus surgery following retinal cryopexy without the use of any external exoplants. [13][14][15] These multiple etiologies all combine to result in strabismus often seen following vitreoretinal surgery.…”

“…7 Orbital scarring and mass effect of the exoplant are the usual explanations for the development of strabismus, but other potential factors may include local anesthetic toxicity 8 or sensory disturbance. 1 Rates of permanent long-term diplopia following retinal detachment repair vary from 5% to 25%.…”
