The Use of Inner Retinectomy to Relieve Inner Retinal Foreshortening Causing Retinal Detachment in the Setting of Branch Retinal Vein Occlusion

Abstract EN

A 61-year-old Japanese woman presented with impairment of her left vision due to macular schisis secondary to branch retinal vein occlusion.

Her left vision was 20/50, and schisis was observed inferotemporally.

She underwent phacoemulsification and aspiration, implantation of the intraocular lens, and removal of the epiretinal membrane and internal limiting membrane.

Her visual acuity stabilized ~20/50 for two and a half years after the initial surgery.

However, she developed macula-involving retinal detachment, and her visual acuity declined to counting fingers.

She underwent pars plana vitrectomy and removal of the residual vitreous cortex together with the inner retina within the area of vein occlusion.

After the removal of silicone oil and the addition of an encircling buckle, the retina remained attached and visual acuity improved to 20/60 at one year after the final surgery.

The combination of rhegmatogenous and tractional detachment in the area of schisis was suspected, and vitrectomy with inner retinectomy was effective.
