Abstract
Background The aim of this study is to evaluate the safety and efficacy of transconjunctival cryo-assisted orbitotomy for extraction of intraconal cavernous hemangioma. Methods The study was performed at the Mansoura ophthalmic center, Mansoura University, Egypt from May 2015 to August 2018. It included 18 patients with orbital intraconal cavernous hemangioma. In all cases, preoperative orbital MRI with contrast was performed, transconjunctival approach was used and cryo-assisted extraction of the lesion was performed. Cases were followed for six months after surgery. Results This study included 18 patients with intraconal cavernous hemangioma, ten females (55.6%) and eight males (44.4%) with a mean age 35.6 years. All lesions were located in the intraconal space, eight cases (44.5%) were lateral to the optic nerve, four cases (22.2%) were above the optic nerve, and six cases (33.3%) were below the optic nerve. Postoperative complications included three cases (16.7%) that showed postoperative diplopia due to lateral rectus paresis that improved in all cases within six months, one case (5.6%) that showed postoperative retrobulbar hemorrhage and proptosis that resolved within two weeks without sequelae, and four cases (22.2%) that showed subconjunctival hemorrhage, which resolved within two weeks. Of the two cases with drop of visual acuity preoperative, one case (5.6%) showed improvement of visual acuity and one case (5.6%) did not improve. Conclusions Transconjunctival cryo-assisted extraction of intraconal cavernous hemangioma represents a safe more conservative and effective technique.
