  Abstract 


Scleral buckling is one of the most effective modality for treatment of rhegmatogenous retinal detachment and in selected cases of retinopathy of prematurity. Although quite safe, it has its own set of associated morbidities. This report presents an interesting case, where the scleral buckle migrated posteriorly reaching up to the optic nerve.

Despite the major advances in instrumentation and wide-field illumination system of vitrectomy surgery, scleral buckle still plays a major role in repair of Stage 4b retinal detachment in retinopathy of prematurity (ROP). Postoperative complications such as refractive changes because of the alteration in shape of eyeball, infection, buckle extrusion or intrusion, anterior and posterior segment ischemia, secondary strabismus, and associated diplopia are known.[1] These bands are cut or removed after 6–9 months to allow the normal growth of the globe and reduce the myopic shift. We present a case of posterior migration of silicone buckle causing impingement of optic nerve head.


  Case Report Top


A 5-year-old boy presented 4.5 years after his scleral buckling surgery for Stage 4b ROP in the right eye. He had a vision of 6/48 in the right eye and no perception of light in the left eye. Right eye had a refraction of -11.00DS with attached retina, dragged vessels, scarring at macula along with posterior indentation of buckle visualized next to the optic disc [Figure 1], left eye was pre phthisical with total retinal detachment. The child born of a twin gestation at 27 weeks had birth weight of 800 gm with Stage 4b ROP in the right eye and Stage V ROP in the left eye in 2013. He had earlier undergone scleral buckling surgery in the right eye with 276 silicone element placed temporally with two anchoring sutures, one on either side of the lateral rectus, along with 240 encircling band anchored with scleral tunnels. Parents were advised band cutting/buckle removal as the buckle was found indenting the optic nerve on ultrasound B scan [Figure 2], but they refused.

Scleral buckling is proven to be an effective treatment for the management of selected group of Stage 4 ROP eyes.[2] There are reports of buckle migration anteriorly through 4 recti muscles,[3] sometimes eroding the overlying conjunctiva and extruding through the upper lid [4] or even migrating up to the cornea leading to corneal groove formation.[5] Buckle may even migrate posteriorly causing impingement of optic nerve head.[6]

In children with ROP there is concern of increasing myopia and impaired growth of the globe. Buckle removal surgery is complicated, especially if abutting the optic nerve, but the risk of further compression on optic nerve continues to haunt the clinician during follow-ups.
