Aim: To report a case of sequential bilateral ischemic central retinal vein occlusion (CRVO) following the third dose of anti-COVID 19 vaccination.

Methods: Observational case report.

Results: A 73-year-old Caucasian male patient, with no known medical history, complained of sudden vision loss in his right eye (RE) 18 days following the third dose of Pfizer-BioNTech anti-COVID 19 vaccination.

Choroidal features in non-neovascular and neovascular pachychoroid diseases.

Purpose: To evaluate choroidal findings on multimodal imaging in eyes within pachychoroid spectrum diseases and to compare quantitative and qualitative choroidal features between non-neovascular (NNV-PDS) and neovascular (NV-PDS) pachychoroid diseases.

Methods: Retrospective cross-sectional study comparing between NV-PDS and NNV-PDS. All patients underwent multimodal imaging including infracyanine green angiography (IFCGA) and swept source optical coherence tomography (OCT) and angiography (OCT-A).

Atypical presentation of bilateral iridoschisis with abnormal visibility of iris vessels: Role of anterior segment optical coherence tomography.

Purpose: To describe clinical and anterior segment optical coherence tomography (AS-OCT) findings in a patient with bilateral iridoschisis and unilateral angle closure glaucoma (ACG) associated with abnormal visibility of iris vessels.

Case Presentation: A 67-year-old male patient with a history of red and painful left eye (LE) one year earlier, presented to our ophthalmology department for a routine examination.Ophthalmic examination of the right eye revealed narrow anterior chamber with sectorial iris atrophy associated to abnormal visibility of an iris vessel.
