Article Synopsis
- A study was conducted to assess the levels of anxiety and depression in glaucoma patients in Brazil, comparing it to the general population's rates of 9.8% for anxiety and 5.8% for depression.
- The research involved 210 adults with glaucoma from four centers, using the PHQ-9 and GAD-7 questionnaires to evaluate mental health symptoms and their correlation with disease severity.
- Findings revealed that 26.90% of patients experienced depression and 25.71% experienced anxiety, indicating higher prevalence rates than the general populace, with early glaucoma linked to anxiety and severe glaucoma linked to depression.

Article Synopsis
- The study compares two surgical techniques for lowering intraocular pressure in patients with refractory primary open-angle glaucoma: micropulse transscleral cyclophotocoagulation and "slow cook" transscleral cyclophotocoagulation.
- Data was collected from 128 eyes, showing significant preoperative differences in mean intraocular pressure (higher in the "slow cook" group) and visual acuity, with both methods achieving effective pressure reduction by the last follow-up.
- At the end of the study, the "slow cook" method resulted in a greater overall reduction in intraocular pressure, while both techniques decreased the number of eye drops needed by patients.
Purpose: To compare the safety and efficacy of micropulse laser (MP-TSCP) and slow coagulation transscleral cyclophotocoagulation (TSCP) with a diode laser for reducing intraocular pressure (IOP) in patients with refractory childhood glaucoma (CG).
Methods: Patients with CG and at least 12 months of medical chart data were included. Data on preoperative and postoperative outcomes were analyzed.
Lost to follow-up of patients who received intravitreal anti-vascular endothelial growth factor therapy to treat four different retina disorders in an individual center in Brazil.

Objectives: To identify risk factors for loss to follow-up in periodic intravitreal anti-vascular endothelial growth factor injections for the treatment patients with diabetic macular edema, subretinal neovascularization, age-related macular degeneration, and retinal vein occlusion in a single eye center in São Paulo, Brazil.
Methods: This was a retrospective longitudinal study that gathered information from 992 patients who required intravitreal anti-vascular endothelial growth factor drugs over 6 months. The authors included age, eye disease, laterality, monthly income, distance, and payment mode as risk factors.
Purpose: To study the effects of Ologen collagen matrix on the outcomes of the Ahmed glaucoma valve implant.
Study Design: Retrospective case-control multicenter study, conducted at four centers, comparing the 6-month outcomes of Ahmed valve implants with or without Ologen.
Participants: The study included 125 eyes in a 4:1 pairing (25 patients with Ologen matched to 100 patients without Ologen).
Purpose: Late hypotony is an undesirable and challenging complication of glaucoma surgery. We describe our use of the Ologen Collagen Matrix to treat late hypotony developing after trabeculectomy.
Study Design: A retrospective study performed at three eye surgery centers in Brazil.
Introduction: This study evaluated the 6-month performance and safety of micro-invasive glaucoma surgery (MIGS) with iStent inject either with or without cataract surgery.
Material And Methods: Longitudinal retrospective study of 86 surgeries in 49 patients with inadequately controlled open-angle glaucoma (OAG) or ocular hypertension who underwent iStent inject trabecular micro-bypass implantation either alone (isolated group) or combined with cataract surgery (combined group). The two primary outcomes included an intraocular pressure (IOP) drop of ≥20% versus preoperative values (adequate drop) and IOP maintenance between 6 and 18 mmHg (adequate Range).
Purpose: To investigate and describe, among the members of the Brazilian Glaucoma Society (BGS), the practices regarding the perioperative management of anticoagulants (warfarin and aspirin) use in patients scheduled for glaucoma surgery.
Methods: The active members of the Brazilian Glaucoma Society answered a questionnaire evaluating different aspects of their current perioperative management of glaucomatous patients taking warfarin or aspirin.
Results: A total of 52 participants returned a complete questionnaire.
Fluorescein is associated with minor adverse effects during retinal angiography, and most of these effects are not severe and not related to immunological mechanism. However, on rare occasions, anaphylatoid reaction can occur, and fatalities involving fluorescein have been described. Life threatening complications after intravenous injection of sodium fluorescein require immediate intervention.

Because hypotension is a strong predictor of outcome in traumatic brain injury (TBI), we tested the hypothesis that early fluid resuscitation blunts calcium influx in hemorrhagic shock associated to TBI.
