Transorbital Endoscopic Medial Orbitotomy and Decompression of the Optic Nerve in Patients with Endocrine Ophthalmopathy Complicated by Optical Neuropathy

AIM OF STUDY: to improve the results of surgical treatment of patients with endocrine ophthalmopathy complicated by optical neuropathy. For this, medial orbitotomy and decompression of the optic nerve were performed for a patient with endocrine ophthalmopathy, CAS<3, OD=18 mm, OS=23 mm and visual acuity OD=1.0 OS=0.2, using transorbital transconjunctival endoscopic access. The first step was a retro caruncular incision. After that, we defined an access to the medial wall of the orbit with its subsequent resection. Then, we performed ethmoidectomy and approach to the optic nerve canal. Upon completion of bone decompression, we opened periorbitis.RESULTS. The postoperative period was uneventful. In the early postoperative period, regression of exophthalmos was observed OD=18 mm, OS=20 mm, improvement in visual acuity OD=1.0 OS=0.5 . No complications were recorded. A satisfactory result was obtained.CONCLUSION. Transorbital endoscopic medial orbitotomy and optic decompression can be effectively used in the treatment of patients with endocrine ophthalmopathy complicated by optic neuropathy, refractory to conservative therapy. The technique is promising and requires further randomized studies
