To present a modified evisceration technique with full-thickness horizontal sclerotomy and assess post-operative motility long-term outcomes. This is retrospective chart review of patients who underwent single surgeon (TJM). The standard initial steps were performed. Before implant placement, complete radial was extended posteriorly at the 3 9 o'clock positions, 2 mm above optic nerve, longitudinally dividing medial lateral rectus insertions. scleral halves mobilized, allowing them to...

Purpose: This study analyzed the degree and timing of proptosis regression after teprotumumab therapy. Methods: A retrospective all patients who completed 8 infusions at 1 institution from January 1, 2020 to December 31, 2022. Change in was assessed millimeters percentages compared with immediate post-treatment pretreatment proptosis. Results: Of 119 data (mean follow-up 10.56 months, range: 3.05–25.08), 208 (87.39%) eyes 110 had initial improvement. 78 multiple visits, 102 (65.38%) 59...

<b>Aim:</b> To determine the disease causing gene defects in two patients with Meesmann's corneal dystrophy. <b>Methods:</b> Mutational analysis of domains 1A and 2B keratin 3 (K3) 12 (K12) genes from dystrophy was performed by polymerase chain reaction amplification direct sequencing. <b>Results:</b> Novel mutations K12 were identified both patients. In one patient a heterozygous point mutation (429A→C = Arg135Ser) found domain gene. This confirmed restriction digestion. second 27 bp...

Purpose: To review the treatment response of advanced conjunctival squamous cell carcinoma (SCC) to systemic immune checkpoint inhibitor (ICI) therapy at a single institution. Methods: A retrospective patients treated institution from 2015 2024 was conducted identify those with SCC who had been ICI therapy. Advanced disease included orbital invasion tumors, unresectable disease, or metastatic disease. Computed tomography imaging and tumor mutational burden data were evaluated for all...

In this case series, the authors report three patients with severe atopic dermatitis who presented epiphora and conjunctivitis while undergoing dupilumab therapy. On clinical examination, all were found to have punctal stenosis, one having progressed obstruction. An assortment of strategies was elected, including discontinuation dupilumab, treatment conjunctivitis, surgical intervention probing, punctoplasty, silicone intubation. This spotlights stenosis as an important new side effect...

Successful repair of the orbital skeleton restores function and cosmesis by normalizing globe position allowing full motility extraocular muscles. Routine repairs are successful with standard implants. However, defects that irregular or cause volume deficiency can be challenging to repair. The development patient specific implants (PSI) offers an additional tool in complex cases. Herein, we report our experience using PSI for reconstruction.An IRB-approved review was conducted consecutive...

Ophthalmic immune-related adverse events (Eye-irAEs) from immune checkpoint inhibitors can cause visual morbidity. The absence of standardized definitions for Eye-irAEs not only impedes the development evidence-based treatments but also progress in translational research. objective this study was to develop consensus guidance an approach Eye-irAEs. Four ophthalmic physicians (uveitis specialists and neuro-ophthalmologists) drafted Eye-irAE definitions, which were reviewed by...
