Introduction Acute primary angle closure (APAC) is a common ophthalmic emergency for Chinese patients causing potential visual disabilities. According to current guidelines published by developed countries, stepwise protocol (medication laser or paracentesis surgery) recommended management of APAC. However, with APAC in China and countries differ disease characteristics as the have longer attack duration lower success rate breaking solely medication therapy. It has been proved that long risk...

Purpose. To report on an improved botulinum toxin injection with conjunctival microincision for beginners, and to determine the effectiveness of A (BTXA) in treatment patients acute acquired comitant esotropia (AACE). Methods. Medical records 29 AACE were retrospectively analyzed. BTXA was injected into unilateral or bilateral medial rectus muscle without electromyographic guidance. Success defined as total horizontal deviation ≤10 prism diopters (PD) evidence binocular vision. Results....

Purpose: To investigate whether the retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) change with optic head (ONH) size in healthy eyes. Methods: This cross-sectional observational study recruited participants aged ≥50 years. Participants underwent optical coherence tomography–assisted measurements of peripapillary RNFL macular GCC were divided into small, medium, large ONH groups according to disc area (≤1.9 mm2, >1.9 mm2 ≤2.4 >2.4 respectively). The compared for GCC. Linear...

Abstract Purpose To investigate the corneal endothelial damage caused by acute primary angle closure (APAC) and related risk factors for severe cell in Chinese subjects. Methods In this multicentre retrospective study, 160 patients (171 eyes) diagnosed with APAC were recruited. Endothelial density (ECD) morphological changes short after studied. Univariate regression multivariate used to identify associated extent of ECD reduction, including age, gender, education level, patients’ location,...

Rationale: The orbital Langerhans cell histiocytosis (LCH) is rare clinically, due to its ability mimic other conditions, distinguishing LCH from hematoma when these disorders coexist can be particularly challenging. Patient concerns: A 3-year-old boy presented with a 2-week history of unresolved bruising and swelling the left eye. CT revealed well-defined cystic lesion in preseptal tissues eyelid, an incomplete bone structure at lower margin orbit. MRI well-circumscribed circular mass...

Iridocorneal endothelial syndrome is a rare ophthalmic disease, most of which are unilateral and common in women. The rate misdiagnosis missed diagnosis relatively high due to its various clinical manifestations. In this case, the patient presented uncontrollable intraocular pressure, corneal edema leading difficult observation endothelium morphology, accompanied by small amount iris neovascularization. No clearly was made before glaucoma surgery. Further examination performed after...
