Unlabelled: The aim of this study was to evaluate the nailfold videocapillaroscopic examination results from patients with pseudoexfoliative glaucoma (XFG) and to assess the relationship between the results of this examination and the patient's clinical status in the XFG group.
Material And Methods: The studied group consisted of 39 Caucasian patients with XFG and 32 patients in a control group. The patients were classified into two subgroups: the hypertensive pseudoexfoliative glaucoma (hXFG) subgroup and the normotensive pseudoexfoliative glaucoma (nXFG) subgroup. The nailfold videocapillaroscopy (NVC) was performed on all participants. The results of each NVC were classified as having a normal or abnormal pattern.
Results: There was no statistical difference between the results of an abnormal NVC pattern in the study group vs. the control group ( = 0.8773). Microhemorrhages were shown in 30.0% of patients with nXFG vs. the control group (6.25%) ( = 0.0520). Microhemorrhages tended to be more frequent in the XFG group ( = 0.1221). A prevalent number of tortuous capillaries was observed in hXFG patients with advanced glaucomatous neuropathy. Dilatation in the capillaries and microbleedings were observed in the group of patients with lower IOP values. Tortuosity in the capillaries was significantly more frequent in PEXG patients (XFG vs. control: = 0.0386). No relationships between the results of NVC and age, c/d, BCVA, time of treatment, and visual field defect were found.
Conclusions: Specific features of NVC examination differentiate nXFG from hXFG patients. Some capillaroscopic features may correlate with the patient's clinical status of XFG.

Purpose: To evaluate the outcomes of slow-coagulation transscleral cyclophotocoagulation (SC-TSCPC) in pseudoexfoliation glaucoma (PXG).
Methods: A single-center, retrospective non-comparative study including consecutive patients with medically uncontrolled PXG who underwent SC-TSCPC (1250-milliwatt power and 4-second duration). The primary outcome measure was surgical success (defined as intraocular pressure (IOP) between 6 - 21 mmHg with ≥20% reduction compared to baseline and no need for further glaucoma surgeries or development of vision-threatening complications).

Background: The aim of the present study was to compare the rates of change in Ganglion Cell- Inner Plexiform Layer (GCIPL) and Retinal Nerve Fiber Layer (RNFL) thickness, as measured by Optical Coherence Tomography (OCT) Guided Progression Analysis (GPA) program in control group, Primary Open Angle Glaucoma (POAG) and Pseudoexfoliation Glaucoma (PXG) eyes.
Methods: 60 POAG and 60 PXG patients and 30 control group patients were included in the study. Patients diagnosed with glaucoma were divided into two groups as mild (Mean deviation (MD) > -6.

To examine ultrastructural changes in the trabecular meshwork (TM) in patients with primary and secondary glaucoma using scanning electron microscopy (SEM). This was a qualitative descriptive hospital-based study on the ultrastructure of the TM. Pure TM samples were collected after microincisional trabeculectomy from 26 patients with primary or secondary glaucoma and 10 control samples from eye bank donor corneas.

Objective: To determine the risk factors for subsequent intraocular lens (IOL) surgery among eyes undergoing either combined or sequential phaco-vitrectomy.
Design: Retrospective cohort study.
Participants: Adult patients undergoing phacoemulsification at 8 United Kingdom National Health Service clinical centers between July 2003 and March 2015.
Introduction: The aim of our study was to assess the outcome of Gore-Tex sutures in minimally invasive scleral fixation of subluxated posterior chamber intraocular lenses (PCIOLs) and to demonstrate a method for validating the lens position.
Methods: Retrospective study of patients who underwent lasso in-the-bag scleral fixation of a subluxated PCIOL using the snare technique with Gore-Tex suture from 2019 to 2021 in a single tertiary medical center. Functional outcome was analyzed by clinical assessment, and anatomical outcome, by ultrasound biomicroscopy (UBM).
