Abstract Details



Purpose:

Assessment of functional and anatomic efficacy of transscleral approach for secondary traumatic retinoschisis complicated by retinal detachment

Setting:

Cheboksary branch of S. Fyodorov Eye Microsurgery Federal State Institution, Russia

Methods:

Secondary posttraumatic bullous peripheral retinoschisis complicated by retinal detachment in a 20-year old patient was addressed by 25-ga vitrectomy. Posterior hyaloid membrane was elevated using aspiration technique, and vitreous cavity was filled with perfluorocarbon liquid (PFCL). Since retinal tears were not detected neither pre- nor intraoperatively, external wall of retinoschisis cavity was punctured ab externo by an ex tempore curved 30-ga needle after careful localization of retinoschisis projection. Under visual control from the vitreous side external drainage of intraand subretinal fluids was carried out till complete evacuation of the intraretinal fluid. Retinal endoscopic laser photocoagulation was performed at the completion of the first surgery. Five days later PFCL-air exchange was carried out

Results:

Complete anatomic retinal and retinoschisis reattachment was achieved. BCVA increased from 0.05 to 0.15 after surgery. At 18 months post-surgery BCVA improved up to 0.55, contrast sensitivity increased, visual fields expanded, and anatomical attachment was stable

Conclusions:

Vitrectomy with transscleral drainage of intraand subretinal fluids and endoscopic laser photocoagulation of retinoschisis area is effective and safe, but more observations with longer follow-ups are necessary
