Purpose: We report two cases of optic nerve pathology after the administration of the Pfizer-BioNTech and AstraZeneca-Oxford COVID-19 vaccines, respectively, and describe the implications for management of post-vaccination central nervous system (CNS) inflammation., Case Reports: A 69-year-old woman presented with bilateral optic nerve head oedema, 16 days after the second dose of the Pfizer-BioNTech vaccine. She was diagnosed with post-vaccination CNS inflammatory syndrome and was treated for five days with intravenous methylprednisolone at a dose of 1 gram per day. Her optic disc swelling improved, and her vision stabilised. A 32-year-old woman presented six days after her first dose of the AstraZeneca-Oxford vaccine with two days of sudden onset of progressive blurring of vision in her left eye. Posterior segment examination revealed left optic disc swelling, and an MRI of the brain, orbit, and cervical spine was significant for left optic nerve enhancement. The patient was diagnosed with a unilateral post-vaccination optic neuritis. She was treated with a three-day course of intravenous methylprednisolone followed by oral prednisone. Her optic disc swelling and visual field improved, and she recovered 6/6 vision., Conclusions: Clinicians and patients should be aware of the potential for post-vaccination CNS inflammatory syndromes associated with COVID-19 vaccine administration. Neuroimaging and cerebrospinal fluid analysis may aid in the diagnosis of the cause of vision loss. Further studies are needed to evaluate the spectrum and frequency of optic nerve involvement associated with COVID-19 vaccination.

Purpose: To evaluate the effect of optic nerve sheath fenestration (ONSF) on the rate of visual function improvement in patients with pseudotumor cerebri syndrome (PTCS)., Methods: Retrospective chart review of patients with PTCS who underwent ONSF between 1998 and 2017. Visual function was evaluated by evaluating visual field (VF), mean deviation (MD), retinal nerve fiber layer (RNFL) thickness, papilledema grade, and visual acuity (VA) prior to and after ONSF., Results: Seventeen female patients aged 17 to 36 years underwent unilateral ONSF. Follow-up averaged 40.1 months. VF MD improved steadily in both eyes up to 12 months. Average RNFL thickness improved in the operated eye from 347 ± 166 mm to 92 ± 27 mm ( p  < .001) and the non-operated eyes from 306 ± 165 mm to 109 ± 46 mm ( p  < .001). The grade of papilledema improved in the operated eye from 3.3 ± 1.3 to 0.3 ± 0.7 and the non-operated eye from 3.0 ± 1.6 to 0.18 ± 0.4. There was an exponential rate of improvement in papilledema and RNFL thickness, with the greatest improvement occurring within the first 30 days. Average visual acuity remained intact in both eyes before and after surgery., Conclusions: ONSF in appropriately selected patients leads to rapid improvement in papilledema and a steady recovery in VF.

Purpose: To report a case of congenital alacrima in a patient with Blepharophimosis Syndrome (BPES)., Methods: Case report of a 9-month-old female who presented with severe dry eyes. Further investigation revealed bilateral absence of lacrimal glands confirmed by CT. This unique case and its management are discussed., Results: Conservative management with artificial tears and ointment did not treat the ocular surface dryness. A combination of aggressive lubrication with surgical occlusion of the lower lid punctums was required to improve the corneal surface., Conclusion: BPES can be associated with many ophthalmic and facial abnormalities. Review of the pubmed literature, reveals this is the first reported case of alacrima and BPES. Patient with alacrima have severe ocular surface dryness, which requires aggressive and life long lubrication and tear supplementation.
