Purpose: The aim of this study is to describe a slit-modified 23-gauge infusion trocar designed to enable early postoperative hypotony-free sclerotomy closure by allowing scleral suturing prior to complete trocar removal, and to report initial clinical outcomes in eyes with proliferative diabetic retinopathy with or without vitreous hemorrhage (PDR + H and PDR). Methods: A standard 23-gauge metallic (titanium) trocar was modified by creating a longitudinal slit that permitted passage of a suture needle while the trocar remained partially engaged within the scleral tunnel. At the end of pars plana vitrectomy, a transscleral suture was placed through the slit with the knot prepared prior to trocar removal, followed by simultaneous trocar extraction and suture tightening. Eighteen consecutive patients undergoing vitrectomy for PDR (fourteen with vitreous hemorrhage [PDR + H]; four without) were included. Intraocular pressure (IOP) was recorded preoperatively, immediately after sclerotomy closure (postoperative baseline), and at 8 and 24 h postoperatively. The study was designed as an exploratory pilot feasibility and safety evaluation of a slit-modified infusion trocar in 23-gauge vitrectomy. The primary outcomes were postoperative IOP stability and wound leakage. Secondary outcomes included early hypotony, postoperative hemorrhage, choroidal effusion, and the need for additional suturing. Results: All procedures were completed without intraoperative complications. The mean IOP was 14.83 ± 2.50 mmHg preoperatively, 13.33 ± 1.53 mmHg immediately after closure, 14.17 ± 3.01 mmHg at 8 h, and 15.17 ± 1.79 mmHg at 24 h. No cases of wound leakage or early postoperative hypotony were observed in either subgroup. One eye exhibited a transient IOP increase at 8 h; no choroidal effusion, postoperative hemorrhage, or need for secondary suturing occurred. Endotamponade consisted of balanced salt solution (BSS) in eight eyes, SF6 in seven eyes, silicone oil in two eyes, and air in one eye. Conclusions: The slit-modified infusion trocar enables secure, hypotony-free closure of the infusion sclerotomy by eliminating the open-wound interval during trocar removal. This simple biomedical device modification provides stable early postoperative IOP across different tamponade agents and appears safe and feasible in high-risk eyes with PDR.

Purpose To investigate the characteristics of referral for glaucoma surgery and compare surgical practices in various European regions in 2025. Methods Data of 300 eyes of 300 consecutive patients undergoing glaucoma surgery were analysed using a standardized questionnaire and compared between geographical regions. Glaucoma specialists from one centre per country provided data on demographics, glaucoma types, intraocular pressure (IOP), visual field and structural metrics, types of surgery and referral timeliness (timely, later than optimal, late). Results The median (quartiles) age was 72 (64–78) years. Primary open angle glaucoma (52.0%) and pseudoexfoliative glaucoma (23.0%) were the most common glaucoma types. Median disease duration was 75 (28–144) months, preoperative IOP 22 (18–28) mmHg, mean deviation − 14.47 (− 21.60 to − 7.85) dB, and retinal nerve fibre layer thickness 60 (50–75) µm. Trabeculectomy (38.3%), minimally invasive bleb forming surgeries (28.3%), and drainage devices (11.3%) were the predominant procedures; 18.7% of the surgeries were combined with phacoemulsification. More severe disease was associated with filtering or drainage device surgery (p < 0.001). Referral was timely in 34.7%, later than optimal in 35.7%, and late in 29.7%. Late referrals were associated with higher IOP, more advanced MD, and thinner RNFL (p < 0.001). Regional differences were significant for common glaucoma types (p = 0.013) and surgical choice (p < 0.0001). Late and later-than-optimal referrals ranged between 22% and 38.3%, and 30.0% and 41.7% between the regions, respectively. The proportion of timely referrals in the East European region (20%) was significantly lower than that in the South and West European (approximately 40%) and North European (31.7%) regions (p = 0.019). Conclusions Marked differences exist in Europe in glaucoma referral timeliness and surgical practice. Late referral remains frequent and associated with advanced structural and functional damage in Europe.

Background/Aims: The goal of glaucoma care is to preserve vision and quality of life This study aimed to develop, and rank patient-centered priorities for glaucoma care in Croatia and compare them with the perspectives of ophthalmologists. Methods: A five-phase, Delphi-based national study was conducted involving patients of the Croatian National Glaucoma Referral Center and Croatian ophthalmologists. An initial 20-item questionnaire was completed by 75 patients to identify patient priorities in glaucoma care. The most frequent responses were synthesized into a final 12 patient-centered priority statements, which patients and clinicians ranked independently. Rankings were compared overall and across prespecified patient and clinician subgroups. Results: The 20-item questionnaire informed a final 12-item survey completed by 130 patients and 97 ophthalmologists. Highest-ranking items across stakeholders were impaired quality of life and fear of losing sight or independence; patient associations ranked lowest. Clinicians emphasized reducing topical therapy burden and side-effects, whereas patients prioritized innovative and curative treatments (including vision restoration), faster, simpler diagnostics, and better communication with clinicians. Subgroup analyses showed stable patterns across clinician groups; among patients, later disease stage shifted focus toward disease control, longer treatment duration increased preference for innovation, and urban–rural differences were minimal. Conclusion: This study provides a ranked, stakeholder-informed set of glaucoma-care priorities for Croatia. Patient perspectives centered on preventing sight loss, preserving independence, and reducing treatment burden, while highlighting unmet needs in innovation, diagnostics, and communication. These findings complement ongoing European Glaucoma Society initiatives and may inform future Europe-wide strategies in patient-centered glaucoma care.

Background: Obstructive sleep apnea (OSA) is increasingly recognized as a potential risk factor for glaucoma due to its association with intermittent hypoxia and vascular dysregulation. The aim of this study was to investigate early glaucomatous changes in the eyes of patients with OSA. Methods: This case–control study included 25 patients with OSA and 25 age- and sex-matched healthy controls. According to the STOP-Bang Questionnaire, patients with an intermediate or severe risk of OSA underwent polysomnography. Based on the apnea-hypopnea index, only patients with severe OSA were included in the study group. All participants underwent a full ophthalmological examination, with measurements of the retinal nerve fiber layer (RNFL) and ganglion cell layer (GCL) thickness performed using optical coherence tomography (OCT). Results: Statistical comparisons revealed that intraocular pressure (IOP) was slightly elevated, while central corneal thickness (CCT) was slightly reduced in patients with OSA compared to healthy controls. OCT measurements showed an overall reduction in both RNFL and GCL thicknesses in the OSA group. Among these findings, only the differences in average and minimum GCL thickness in the left eye reached statistical significance. Conclusions: The results of our study indicate significant thinning of the GCL in patients with OSA, suggesting possible early glaucomatous changes and a potential link between OSA and glaucoma. Given the increasing prevalence of OSA, further large-scale, long-term studies are needed to better understand this relationship and its clinical implications.

We report a case of herpes simplex virus type 1 (HSV-1) anterior uveitis evolving into an acute iris transillumination-like syndrome with secondary pigmentary glaucoma, highlighting diagnostic challenges and treatment considerations. A 61-year-old immunocompetent woman presented with unilateral anterior uveitis characterized by keratic precipitates and mild anterior chamber inflammation. The condition was initially treated with topical and subconjunctival corticosteroids without antiviral therapy. After an initial resolution of symptoms, upon the cessation of treatment, the patient developed features resembling unilateral acute iris transillumination (UAIT) syndrome with elevated intraocular pressure, diffuse pigment dispersion, and progressive iris transillumination defects. Aqueous polymerase chain reaction (PCR) testing confirmed the presence of HSV-1. Despite the initiation of antiviral therapy, the condition progressed to severe pigmentary glaucoma, with unreliable intraocular pressure measurements due to prior LASIK surgery. Cataract extraction, pars plana vitrectomy, and Ahmed valve implantation were performed, with only partial recovery of visual acuity. This case illustrates that HSV-1 uveitis can mimic or transition into a UAIT-like syndrome, possibly due to steroid use without concurrent antiviral treatment, which may exacerbate viral replication and damage to the iris pigment epithelium. Aqueous PCR testing aids in differential diagnosis, but indicative medical history and clinical findings should remain instrumental. Clinicians should maintain a high index of suspicion for herpetic etiology in anterior uveitis cases and initiate prompt antiviral treatment to prevent potentially sight-threatening complications.

Polymerase chain reaction (PCR) testing confirmed HSV-1 infection. Despite the initiation of antiviral therapy, her condition progressed to severe pigmentary glaucoma, with intraocular pressure measurements fluctuating due to prior LASIK surgery affecting tonometry accuracy, necessitating cataract extraction, vitrectomy, and Ahmed valve implantation. The eye eventually stabilized with partial recovery of visual acuity. This case illustrates that HSV-1 anterior uveitis can mimic or transition into a UAIT-like syndrome, possibly due to steroid use without concurrent antiviral treatment, which may exacerbate viral replication and tissue damage to the iris pigment epithelium. Aqueous PCR testing aids in differential diagnosis, but indicative medical history and clinical findings should remain instrumental. Clinicians should maintain a high index of suspicion for viral etiology and initiate prompt treatment with antiviral therapy to prevent potentially sight-threatening complications such as UAIT-like exacerbation and pigmentary glaucoma.

The aim of this study is to present interesting images of a clinical case of asymmetrical bilateral ciliary body cysts associated with pseudoexfoliative syndrome (PEX), leading to unilateral reverse pupillary block and subsequent secondary angle-closure glaucoma in a 64-year-old patient who presented with vision loss and redness, revealing angle-closure glaucoma in the left eye. Slit lamp examination showed an asymmetrical iris configuration between the eyes, with a normal appearance in the right eye and an inverted “volcano-shape” iris appearance, corresponding to reverse pupillary block, with pseudoexfoliation in the left eye. Multimodal imaging confirmed the presence of bilateral ciliary body cysts, which were unexpectedly identified in the right eye. The patient’s secondary angle-closure glaucoma in the left eye was likely due to anterior displacement of the iris from these cysts. Following an inadequate response to topical and systemic treatments, the patient underwent trabeculectomy in the left eye, successfully stabilizing the intraocular pressure (IOP) and leading to the resolution of the reverse pupillary block. This case underscores the importance of thorough ocular examination and multimodal imaging in diagnosing complex clinical presentations like secondary angle-closure glaucoma stemming from the combination of ciliary body cysts’ pressure towards the angle, the pseudoexfoliative material component, and the reverse pupillary block configuration. All of the findings provided critical diagnostic clues leading to the identification of the underlying pathology.

Purpose To report the prevalence of undiagnosed glaucoma, as well as demographic characteristics and risk factors among glaucoma suspects who were detected in a publicly promoted intraocular pressure (IOP) based glaucoma screening event. Methods A total of 2468 subjects older than 18 years participated in the glaucoma screening event in Zagreb, in 2014, which included a medical interview and IOP measurement using Icare tonometer. 256 subjects (10.37%) were identified as glaucoma suspects, out of which 125 (5.06%) subjects underwent further detailed ophthalmic examination and were classified into five diagnostic groups. Results The prevalence of all types of newly diagnosed glaucoma was 1.175%, while the prevalence of ocular hypertension (OH), primary open-angle glaucoma (POAG), primary angle closure (PAC) and secondary glaucoma (SG) was 0.16%, 0.89%, 0.16% and 0.12%, respectively. The prevalence of newly diagnosed glaucoma in glaucoma suspects was 23.2%. 17.60% of glaucoma suspects were diagnosed as POAG. Older age was statistically significantly associated with POAG (p = 0.001) and PAC (p = 0.029). At the univariate level, refractive errors were a statistically significant predictor of POAG, and those with hyperopia had more than three times larger odds for POAG. At the multivariate level, none of the predictors reached statistical significance. Conclusion Successful cooperation between healthcare institutions and media can be a useful way of increasing awareness and detection of individuals at an increased risk for developing glaucoma.
