Purpose: To show poor adhesion between the conjunctiva and the sclera in eyes with superior conjunctivochalasis (CCh) and to introduce a new surgical approach by reinforcing adhesion between the conjunctiva and the sclera for correcting this deficiency.
Methods: After conjunctival peritomy and removal of the loose Tenon remnants, "Tenon reinforcement" for conjunctival adhesion to the underlying sclera was achieved by transplantation of cryopreserved amniotic membrane with fibrin glue (group A, 9 eyes of 6 patients) or 10-0 nylon sutures (group B, 8 eyes of 6 patients) in 17 eyes of 12 patients with refractory superior CCh.
Results: The mean age of patients was 68.2 +/- 9.8 years (range, 54-80 years). Superior CCh was associated with a superior limbic keratoconjunctivitis (SLK)-like clinical feature before surgery and found to exhibit dissolved Tenon capsule during surgery in all patients. During a mean follow-up of 3.7 +/- 1.9 months after surgery, all eyes achieved smooth conjunctival surface without any sign of CCh. Complete resolution of symptoms was seen in 9 eyes (52.9%) and significant resolution in 8 eyes (47.1%). There was no significant difference between groups A and B in improvement of symptoms and signs. No complications related to surgery were noted during follow-up.
Conclusions: We propose that loose and dissolved Tenon tissue is correlated with the development of superior CCh, which may result in an SLK-like appearance by blink-related microtrauma. Reinforcement of conjunctival adhesion onto the sclera by amniotic membrane with either fibrin glue or sutures is effective in alleviating symptoms and signs in eyes with superior CCh.

Department of Ophthalmology, Giresun University, Giresun, Turkey.
Clinical Relevance: The prevalence of male androgenetic alopecia is increasing worldwide. Evaluation of dry eye parameters and meibomian glands of male androgenetic alopecia patients may help to better understand the effect of this disease on dry eye and to provide appropriate treatment for these patients.
Background: The aim of this work is to evaluate the relationship between male androgenetic alopecia, dry eye, and meibomian gland function.

Neovascular age-related macular degeneration and diabetic macular edema are leading causes of vision-loss evoked by retinal neovascularization and vascular leakage. The glycoprotein microfibrillar-associated protein 4 (MFAP4) is an integrin αβ ligand present in the extracellular matrix. Single-cell transcriptomics reveal MFAP4 expression in cell-types in close proximity to vascular endothelial cells including choroidal vascular mural cells and retinal astrocytes and Müller cells.

Background: Vocal fold leukoplakia (VFL), a precancerous lesion of the larynx, is characterized by white plaques on the vocal fold mucous membrane. Currently, there are no reliable biomarkers to predict the recurrence and malignant transformation of VFL. Considering chondroitin sulfate proteoglycan 4 (CSPG4) as a biomarker for malignant tumors such as laryngeal squamous cell carcinoma (LSCC), we conducted this cohort study to evaluate the prognostic influence of CSPG4 expression on VFL patients.

The purpose of this study is to evaluate the effectiveness of intensity-modulated radiation therapy (IMRT) combined with periorbital triamcinolone acetonide injection in treating thyroid eye disease (TED) patients with active extraocular muscle but low CAS. The retrospective observational study was conducted. A total of 156 eligible patients were selected from the TED patient database of the Ophthalmology Department of West China Hospital of Sichuan University.

Purpose: To utilize optical coherence tomography (OCT) and SS-OCT angiography (SS-OCTA) for quantifying morphological changes seen in eyes with recalcitrant neovascular age-related macular degeneration (nAMD) transitioned to intravitreal faricimab injections during the manufacturer's recommended induction phase of treatment.
Methods: Fifty-four treatment-recalcitrant patients (60 eyes) were recruited. OCT and SS-OCTA images were obtained at 0 and 3 months.
