To report a case series of three patients with bilateral uveal effusion syndrome (UES), treated conservatively with oral carbonic anhydrase inhibitors and topical prostaglandin analogues (PAs). Three patients with bilateral UES were treated with the same initial therapy. Topical PA latanoprost 0.005% and acetazolamide 250 mg were administered in order to reduce intraocular pressure, improve uveoscleral outflow, and facilitate resolution of uveal effusion. The chorioretinal detachment resolved within 3 months in two reported patients while the third one underwent surgery on his left eye. After clinical improvement, further oral therapy with acetazolamide was stopped, while topical prostaglandins were continued for at least the next 3 months. All patients were free from recurrence during the follow-up period. Although the usually recommended UES therapy is partial or full-thickness sclerectomy, our case series showed apparent resolution of chorioretinal detachment in two patients on medical therapy alone. Conservative therapy may be the first step before the standard recommended surgical approach, but further studies are needed to verify the effectiveness of reported therapy.

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.

Purpose: 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 permits passage of a suture needle while the trocar remains 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 (14 with vitreous hemorrhage [PDR+H], 4 without) were included. Intraocular pressure (IOP) was recorded preoperatively, immediately after sclerotomy closure (postoperative baseline), and at 8 and 24 hours postoperatively. 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. Mean IOP was 14.83 ± 2.50 mmHg preoperatively, 13.33 ± 1.53 mmHg immediately after closure, 14.17 ± 3.01 mmHg at 8 hours, and 15.17 ± 1.79 mmHg at 24 hours. No cases of wound leakage or early postoperative hypotony were observed in either subgroup. One eye exhibited a transient IOP increase at 8 hours; no choroidal effusion, postoperative hemorrhage, or need for secondary suturing occurred. Endotamponade consisted of balanced salt solution (BSS) in 8 eyes, SF6 in 7 eyes, silicone oil in 2 eyes, and air in 1 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.

An unruptured giant intracranial aneurysm of the internal carotid artery may tend to present with late ocular symptoms. This is the case of a 58-year-old female patient with a giant unruptured aneurysm of the right internal carotid artery. The patient presented with exclusively progressive reduction of visual acuity and visual field defects due to the mass effect of the growing aneurysm. The rupture of the aneurysm occurred before planned treatment. Clinical suspicion and timely recognition as well as prompt treatment play an important role in the final outcome of the management of giant unruptured intracerebral aneurysms.
