Objective: For unilateral Dodge Class Ⅰ optic pathway glioma (OPG-uDCⅠ) without neurofibromatosis type 1, unilateral isolated optic nerve gliomas before the optic chiasm have been confirmed to possibly cause visual deterioration and poor prognosis. For this type of highly selective localized tumor, we explored surgery as the only treatment method. This article retrospectively analyzed and summarized the clinical data of this case series, with the aim of exploring the main technical details and clinical prognosis., Methods: Included were patients with OPG-uDCⅠ without neurofibromatosis type 1 and experiencing vision loss on the affected side. The fronto-orbital approach was used, which was mainly divided into 3 parts: intraorbital, optic canal, and intracranial. All patients underwent prechiasmatic resection without any adjuvant treatments. The follow-up period was 3 months after surgery, and magnetic resonance imaging and contralateral visual acuity were reviewed annually after surgery., Results: All OPG-uDCⅠ cases were completely removed without any adjuvant treatments, and there was no recurrence during the follow-up period. Pathological results showed that, except for 1 adult patient with pilomyxoid astrocytoma (World Health Organization grade Ⅱ), the others all had pilocytic astrocytoma (World Health Organization grade Ⅰ). Five patients experienced transient ptosis, and all recovered 3 months after surgery., Conclusions: For OPG-uDCⅠ without neurofibromatosis type 1, radical prechiasmatic resection of the tumor is possible, without the need for postoperative radiotherapy and chemotherapy., (Copyright © 2023 Elsevier Inc.

Objective: The pterional approach (PA) has been used to remove cranio-orbital lesions that have communicated via the supraorbital fissure (SOF). The supraorbital eyebrow approach (SEA) has become increasingly popular as a minimally invasive approach. However, few reports have examined the SEA for cranio-orbital lesions. We assessed the relative advantages, disadvantages, and selection criteria for these 2 approaches., Methods: The data from all consecutive patients who had undergone removal of a cranio-orbital lesion that communicated via the SOF using the PA or SEA were analyzed., Results: Of the 25 patients, 13 had undergone surgical resection using the SEA and 12 had undergone resection using the PA. The SEA provided better cosmetic satisfaction, resulted in a shorter surgical time, and required a shorter incision (P < 0.05). Proptosis had improved significantly in all the patients. No significant differences were found in the total resection rates, visual outcomes, recovery of ptosis, or other new surgically related complications between the 2 groups (P > 0.05). All the patients were followed up for an average of 21.9 months. One patient in each group had developed recurrence or progression that required radiotherapy. The disease of the other patients with subtotal resection was stable or atrophic., Conclusion: The SEA provided better cosmetic satisfaction, resulted in a shorter surgical time, and required a shorter incision. The SEA might be a more minimally invasive option for lesions communicating via the SOF without obvious hyperostosis. The PA might be more reasonable for lesions with obvious hyperostosis and more extensive lesions in the cavernous sinus., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Background: A pterional-orbital or subfrontal-orbital approach is recommended as a surgical treatment in cranio-orbital lesions. We describe a less invasive approach through an eyebrow incision combined supraorbital minicraniotomy and orbital osteotomy for treating some selected cranio-orbital lesions., Methods: Sixteen patients with different cranio-orbital lesions were treated using this less invasive approach. Postoperative outcomes were evaluated to shed light on specific parameters related to this approach., Results: The 16 patients with cranio-orbital lesions underwent 17 operations. A total resection was achieved in 11 lesions. All the patients were followed up for 3-54 months. Postoperative proptosis improved in all cases. Five cases of visual impairment were improved, but 4 patients with blindness did not recover. One patient with bitemporal hemianopia recovered. Three patients with ocular dyskinesia did not recover. Two patients had transient cranial nerve III palsy, and 2 patients had cranial nerve VI palsy. One had delayed hydrocephalus. One died 1 year later as a result of pulmonary metastases. One recurred and the patient underwent a second operation. All the patients had a modified Rankin Scale score ≤1 at 12 weeks follow-up., Conclusions: Some selected cranio-orbital lesions can be treated through a supraorbital eyebrow approach with orbital osteotomy. The presence of retro-ocular fat allows the orbital lesions to be classified as a lesion of the intraretro-ocular or extraretro-ocular fat. It is safe to resect the lesion of extraretro-ocular fat from the retro-ocular fat interface. However, the lesion with optic nerve and extraocular muscles involved should be removed from the intermuscular septae., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Objective: To describe clinicoradiologic characteristics of orbital sparganosis., Design: Retrospective case series., Participants: We studied 8 patients diagnosed with orbital sparganosis at Zhongshan Ophthalmic Center between 1999 and 2011., Methods: A thorough review of clinical and imaging manifestations., Results: The primary clinical manifestations were redness and edema of the eyelids and conjunctivas (100%); proptosis (mild in 87.5% of cases and severe in 12.5%); subconjunctival yellow-white granulomatous lesions (75.0%); and migratory hyperemic masses of the eyelid or conjunctiva (50.0%). Of the patients, 6 had diffuse orbital or nodular masses on computed tomography imaging, 2 had the "tunnel sign" on magnetic resonance imaging, and 1 had subconjunctival tubular lesions on ultrasound biomicroscopy imaging., Conclusions: Subconjunctival yellow-white granulomatous lesions, migratory hyperemic masses, and the tunnel sign on magnetic resonance imaging are characteristic clues to preoperative diagnosis of orbital sparganosis., (Copyright © 2012 Canadian Ophthalmological Society.
