Unable or unwilling to sign the informed consent form, or unable to adhere to study procedures.\n2. Patients have conditions that significantly interfere with OCTA imaging, such as severe corneal opacity, cataracts, or vitreous hemorrhage.\n3. Patients who develop other concurrent eye diseases or severe comorbidities requiring immediate treatment during the follow-up period-such as glaucoma, uveitis, scleritis, retinal detachment, optic neuritis, diabetic retinopathy, macular hole, retinal neovascularization, sclerosis, Parkinson's disease, or other disorders affecting the retina and optic nerve.\n4. History of intraocular surgery or ocular trauma.\n5. Severe systemic diseases (e.g., serious cardiovascular, cerebrovascular, or hematopoietic disorders), or a history of intracranial surgery or intracranial space-occupying lesions.\n6. Inability to cooperate with ophthalmic examinations or failure to obtain satisfactory OCTA images for other reasons.\n7. Pregnant women, women planning pregnancy or breastfeeding, and patients with drug allergies.\n8. Suspected or confirmed history of alcohol or drug abuse.\n9. Patients currently participating in other clinical trials involving medications.","ALL","6 Years",{"count":19,"type":20},50,"ESTIMATED","OBSERVATIONAL","The goal of this retrospective observational study is to evaluate the effectiveness of retrobulbar glucocorticoid injection in patients with retinal photo-injury. The main questions it aims to answer are:\n\nDoes retrobulbar glucocorticoid injection improve visual outcomes in patients with retinal photo-injury? Does retrobulbar glucocorticoid injection promote recovery of retinal structural and microvascular changes assessed by optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA)? Patients with retinal photo-injury will be retrospectively identified and grouped according to the treatment they received. Clinical and ophthalmic data collected before treatment and during follow-up for up to 6 months will be reviewed, including best-corrected visual acuity (BCVA), fundus photography, spectral-domain OCT (SD-OCT), and OCTA. Visual and retinal imaging outcomes will be compared between the two groups to evaluate the potential effectiveness of retrobulbar glucocorticoid treatment.",[24,25,26],"Retinal Light Damage","Photic Retinopathy","Photic Maculopathy","RECRUITING","2026-10-07",{"date":30,"type":31},"2026-10-09","ACTUAL",{"date":30,"type":20},{"date":34,"type":20},"2027-10-09",{"name":36,"class":37},"Second Affiliated Hospital, Zhejiang University, School of Medicine","OTHER"]
