Abstract

Lens coloboma can occur with ocular or systemic associations like Marfan's and Stickler's syndrome. Causes of poor vision include refractive error, anisometropia and amblyopia. Visual rehabilitation and surgery is technically challenging in these patients. Here we report a child with progressive defective vision with Marfans syndrome and lens coloboma who underwent successful surgery with intraocular lens (IOL) placement. The bag was stabilised with capsule tension ring and iris hooks, and the IOL was further stabilised with optic capture. Postoperatively, the child regained good vision in the operated eye with very good centration of the IOL at three month follow up visit.

 Introduction



Lens coloboma in Marfan's syndrome is infrequently reported.[1],[2] This is due to defective or absent development of the zonules and ciliary body.[3] Surgeryis technically challenging and successful, intraocular lens (IOL) placement depends on coloboma's extent and usage of capsular supportive devices like iris hooks, capsular tension ring (CTR), Cionnis ring or segments. We present the successful visual rehabilitation following IOL placement in the left eye of a child with the above condition.

 Case Report



A 13-year-old boy [Figure 1] with Marfans syndrome presented with progressively decreasing vision in his left eye of unknown duration. His best corrected visual acuity (BCVA) was 20/40 (−0.75/−[email protected]) and 20/125 (−8.0/−[email protected]) in his right eye (RE) and left eyes (LE), respectively. Slit lamp evaluation under mydriasis showed clear lens with coloboma extending from 12 to 2 o'clock (RE) and 9–1 o'clock (LE) [Figure 2] with few intact zonules. As left eye BCVA was low, we decided on surgery with IOL placement, after explaining possibility of subnormal visual outcome due to amblyopia. Following lens aspiration the capsular bag was stabilised with CTR (Aurolab, Madurai, India) [Figure 3], inserting which was technically challenging due to small and irregular colobomatous bag. Three iris hooks were used to stabilise the bag prior to three piece acrylic IOL (Alcon Labs, Texas, USA) implanted in sulcus with optic capture [Figure 4] and [Figure 5].{Figure 1}{Figure 2}{Figure 3}{Figure 4}{Figure 5}

Postoperatively, visual acuity in his LE improved to 20/63 (−[email protected]) with well centered IOL.

 Discussion



Visual rehabilitation is technically challenging due to capsular fornix aspiration, zonular dialysis extension, vitreous herniation and IOL decentration.[3] Lens coloboma in Marfan's poses the difficulty of a small sized capsular bag with notching, in addition to the difficulties encountered in subluxated lens management. Also there exists a possibility of late decentation of IOL placed entirely in bag due to progressive myopia. Hence we decided on bag sulcus fixation of IOL, to aid in long term stability and centration.

The improvement in BCVA post surgery implies that the high myopia causing vision loss may have occurred beyond the amblyogenic years of his life.

IOL implantation can thus be an effective option to provide optimal visual rehabilitation in eyes with progressive vision loss in lens coloboma, in expert hands.
