New insights on circumscribed choroidal hemangioma: "bench to bedside".

Circumscribed choroidal hemangioma is a rare vascular hamartoma of the choroid, presenting as a red-orange mass at the posterior pole on fundoscopic examination. Despite its benign origin, associated complications such as subretinal fluid, serous retinal detachment, retinoschisis and neovascular glaucoma may lead to serious visual impairment in more than half patients. Because of its similarity to amelanotic choroidal melanoma and choroidal metastasis, differential diagnosis is still challenging for specialists. Multimodal imaging such as ultrasonography, fluorescein angiography, indocyanine green angiography, optical coherence tomography, and optical coherence tomography angiography guides the clinician to the correct diagnosis and the proper follow-up. Treatment is indicated in symptomatic cases in order to resolve exudation and improve visual acuity. Treatment options include photocoagulation, transpupillary thermotherapy, radiation therapy, photodynamic therapy and anti-vascular endothelial growth factor therapy. Currently, photodynamic therapy is the treatment of choice due to its effectiveness and safety. The purpose of this review is to describe the latest knowledge in the etiopathogenesis of the circumscribed choroidal hemangioma, the most recent multimodal imaging findings, and the available treatment options.

Correlation between retinal sensitivity and retinal vascular perfusion after idiopathic epiretinal membrane peeling.

BACKGROUND: To evaluate the correlations between anatomical and functional changes after idiopathic epiretinal membrane (iERM) surgery. METHODS: In this prospective, observational, single-center study, consecutive patients who underwent iERM peeling were enrolled. Reported data were pre- and postoperative best-corrected visual acuity (BCVA), retinal sensitivity (RS) and fixation stability values on microperimetry, structural macular features on SD-OCT and OCTA. RS of foveal and parafoveal area was analysed and two sub-groups were identified whether RS improved or remained unchanged/worsened after surgery; consequently, vascular perfusion density (VPD) of the same area was studied. RESULTS: Twenty-nine eyes of 29 patients were examined. The post-operative improvement in terms of BCVA, RS and fixation within the central 4 degrees was significant (p < 0.001, p < 0.001, p = 0.001), as well as the foveal thickness and macular volume change/reduction (p < 0.001). The pre-operative superficial VPD, choriocapillaris VPD and capillary free zone (CFZ) area were significantly reduced compared to the fellow healthy eye (p = 0.001, p = 0.02, p < 0.001). Choriocapillaris VPD showed a statistically significant increase after surgery (p < 0.02). Superficial, deep and choriocapillaris VPD of the improved RS group showed a significant increase both in foveal (p = 0.03, p = 0.03, p = 0.01) and parafoveal areas (p = 0.01, p = 0.03, p = 0.001). CONCLUSIONS: We reported a higher VPD in the retinal area that experienced a retinal sensitivity improvement 6 months after ERM surgery. This result objectifies the tight bond between visual function and retinal perfusion in ERM patients.

Artificial intelligence in diabetic retinopathy screening: clinical assessment using handheld fundus camera in a real-life setting.

AIM: Diabetic retinopathy (DR) represents the main cause of vision loss among working age people. A prompt screening of this condition may prevent its worst complications. This study aims to validate the in-built artificial intelligence (AI) algorithm Selena+ of a handheld fundus camera (Optomed Aurora, Optomed, Oulu, Finland) in a first line screening of a real-world clinical setting. METHODS: It was an observational cross-sectional study including 256 eyes of 256 consecutive patients. The sample included both diabetic and non-diabetic patients. Each patient received a 50°, macula centered, non-mydriatic fundus photography and, after pupil dilation, a complete fundus examination by an experienced retina specialist. All images were after analyzed by a skilled operator and by the AI algorithm. The results of the three procedures were then compared. RESULTS: The agreement between the operator-based fundus analysis in bio-microscopy and the fundus photographs was of 100%. Among the DR patients the AI algorithm revealed signs of DR in 121 out of 125 subjects (96.8%) and no signs of DR 122 of the 126 non-diabetic patients (96.8%). The sensitivity of the AI algorithm was 96.8% and the specificity 96.8%. The overall concordance coefficient k (95% CI) between AI-based assessment and fundus biomicroscopy was 0.935 (0.891-0.979). CONCLUSIONS: The Aurora fundus camera is effective in a first line screening of DR. Its in-built AI software can be considered a reliable tool to automatically identify the presence of signs of DR and therefore employed as a promising resource in large screening campaigns.

Optic neuritis following COVID-19 vaccination: Do autoimmune diseases play a role?

PURPOSE AND CONTEXT: We report two cases of optic neuritis following Pfizer-BioNTech COVID-19 vaccination in patients with autoimmune diseases. Post-vaccine optic neuritis, although rare, is reported in the literature and an autoimmune mechanism seems to be involved, especially in genetically predisposed subjects. METHOD: Report of two cases of optic neuritis following COVID-19 vaccination in patients with autoimmune diseases. KEY RESULTS: He novelty of this article is the fact that the two patients had a medical history of autoimmune diseases (Hashimoto thyroiditis and ankylosing spondylitis), a point of interest for research because it is not yet clear whether this could constitute a risk factor for adverse events after vaccination. CONCLUSIONS: The reactogenicity of COVID-19 mRNA vaccine in individuals suffering from immune-mediated diseases is yet to be elucidated and it is being increasingly investigated. Our paper supports the hypothesis that patients who are already affected or predisposed to autoimmune or autoinflammatory disorders should be carefully evaluated for the benefits and risks of COVID-19 mRNA vaccination.

Quantification of Carbonic Anhydrase Inhibitors and Metabolites in Urine and Hair of Patients and Their Relatives.

Carbonic anhydrase inhibitors (CAIs) are prescription drugs also used in doping to dilute urine samples and tamper with urinalyses. Dorzolamide, brinzolamide, and acetazolamide are prohibited by the World Anti-Doping Agency. Detecting CAIs and their metabolites in biological samples is crucial to documenting misuse in doping. We quantified dorzolamide, brinzolamide, acetazolamide, and their metabolites in the urine and hair of 88 patients under treatment for ocular hypertension or glaucoma. Samples of the patients' relatives were analyzed to assess potential for accidental exposure. After washing, 25 mg hair was incubated with an acidic buffer at 100 °C for 1 h. After cooling and centrifugation, the supernatant was analyzed by ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS). Urine (100 µL) was diluted and centrifuged before UHPLC-MS/MS analysis. Run time was 8 min through a reverse-phase column with a mobile phase gradient. MS/MS analysis was performed in a multiple-reaction monitoring mode after positive electrospray ionization. Median urinary concentration was 245 ng/mL (IQR: 116.2-501 ng/mL) for dorzolamide, 81.1 ng/mL (IQR: 35.9-125.3 ng/mL) for N-deethyl-dorzolamide, 0.77 ng/mL (IQR: 0.64 ng/mL-0.84 ng/mL) for N-acetyl-dorzolamide, 38.9 ng/mL (IQR: 20.4-79.2 ng/mL) for brinzolamide, and 72.8 ng/mL (IQR: 20.7-437.3 ng/mL) for acetazolamide. Median hair concentration was 0.48 ng/mg (IQR: 0.1-0.98 ng/mg) for dorzolamide, 0.07 ng/mg (IQR: 0.06-0.08 ng/mg) for N-deethyl-dorzolamide, 0.40 ng/mL (IQR: 0.13-1.95 ng/mL) for brinzolamide. Acetazolamide was detected in only one hair sample. Dorzolamide and brinzolamide were detected in the urine of three and one relatives, respectively. Cutoff concentrations of urinary dorzolamide and brinzolamide are necessary to preclude false positives due to contamination or passive exposure. We reported the first concentrations of brinzolamide in hair.

Pachychoroid spectrum disease and choriocapillary flow analysis in patients with Cushing disease: an optical coherence tomography angiography study.

PURPOSE: To investigate the presence of pachychoroid spectrum disease (PSD) in patients with Cushing disease (CD) and to evaluate subfoveal choroidal thickness (SFCT) and choriocapillary flow using spectral domain OCT (SD-OCT) with the enhanced depth imaging (EDI) and optical coherence tomography angiography (OCT-A). METHODS: Thirty-two patients with CD and 32 age- and sex-matched healthy volunteers were enrolled in this observational study. All participants had a complete ophthalmic examination including SD-OCT with EDI and OCT-A, and were subjected to the Perceived Stress Scale test (PSS). All patients with CD had hormone test including 24-h urinary-free cortisol (UFC) and plasma adrenocorticotropic hormone (ACTH). We compared SFCT and choriocapillary vessel density (CVD) between the two groups and evaluated the presence of PSD. We investigated the association of hormone level, SFTC, CVD with the presence of CD; the association between the hormone level, SFTC, CVD, the CD disease activity, and duration with the presence of PSD in CD patients; and the association between SFTC and CVD with the hormone level, the CD disease activity, and duration in CD patients. RESULTS: Higher values of SFCT and CVD were associated with CD (ß: 0.028, 95% CI: 0.014; 0.041; ß: 0.912, 95%CI: 0.205; 1.62, respectively). Twelve patients with CD (37.5%) reported a PSD in at least one eye, whereas no subject was found in control group (p < 0.001); in particular, 11 CD patients (34%) presented pachychoroid pigment epitheliopathy (PPE) and 1 CD patient (3%) presented polypoidal choroidal vasculopathy/aneurysmal type 1 neovascularization (PCV/AT1). In patients with CD, a significant positive association between SFCT and PSD was found (ß: 0.010, 95% CI 0.001; 0.019). CONCLUSION: A chronic state of hypercortisolism may have direct implications on the choroid. Patients with CD had higher SFCT values and a significant change in the choriocapillary flow compared to healthy controls. Moreover, PSD was observed only in CD patients.

Punctate inner choroidopathy reactivation following COVID-19: A case report.

PURPOSE: The purpose of this study is to report our experience with a case of punctate inner choroidopathy (PIC) reactivation following COVID-19. CASE REPORT: A 29-year-old caucasian woman with past ophthalmological history of bilateral PIC reported sudden visual acuity decrease in her right eye (RE) 3 weeks after SARS-CoV-2 infection. Her best-corrected visual acuity (BCVA) was 20/32 in RE; fundus examination and multimodal imaging (including indocyanine-green angiography, fundus autofluorescence, and optical coherence tomography) was consistent with unilateral PIC reactivation. The active choroidal lesions responded to high-dose corticosteroids, with functional improvement. CONCLUSION: Sars-CoV-2 infection could induce autoimmune and autoinflammatory dysregulation in genetically predisposed subjects. We report a case of PIC reactivation following COVID-19.

Retinal obliterative vasculitis associated to contralateral retinal neovascularization in membranoproliferative glomerulonephritis.

PURPOSE: To report our experience with a peculiar case of asynchronous bilateral retinal vascular occlusion in a patient suffering from membranoproliferative glomerulonephritis. CASE REPORT: A 57-year-old dialysed male affected by membranoproliferative glomerulonephritis who underwent kidney transplantation complained of a sudden vision loss in his right eye (RE). His best-corrected visual acuity (BCVA) was 20/40 in RE and 20/20 in the left eye (LE); ophthalmological and fluorangiographic examinations revealed unilateral retinal obliterative vasculitis with panuveitis and apparent sparing of contralateral eye. About 6 months later the patient developed a branch retinal vein occlusion associated with a papillary neovascular membrane in LE. Corticosteroid therapy was administered and immunosuppressant dosage was increased with macular oedema reduction in both events. CONCLUSION: We report a case of unilateral retinal obliterative vasculitis and subsequent contralateral retinal neovascularization and branch retinal vein occlusion in a patient affected by membranoproliferative glomerulonephritis.

Sclerochoroidal calcification as an incidental finding during oncological staging of a patient with parotid malignancy: A case report.

INTRODUCTION: Incidental finding of mass lesion in the choroid represents a very challenging situation for the ophthalmologist. We describe a case of an incidental, computed tomography (CT)-hyperintense, choroidal lesion in a patient with parotid malignancy and renal failure, and how multimodal imaging helped us reaching the correct diagnosis. CASE DESCRIPTION: A 63-year-old man with parotid gland malignancy was brought to our attention because preoperative staging CT showed a hyperintense choroidal lesion of the right eye. Fundus examination showed a yellow elevated lesion near the superior temporal branch retinal artery. Enhanced depth imaging optical coherence tomography (EDI-OCT), A- and B-scan ultrasonography, and Indocyanine Green Angiography (ICGA) allowed us to exclude a malignant lesion and to diagnose a sclerochoroidal calcification. CONCLUSION: Multimodal imaging can guide the clinician to choose the appropriate therapeutic approach even in case of uncommon conditions like sclerochoroidal calcification.

Oxidative stress in retinal pigment epithelium impairs stem cells: a vicious cycle in age-related macular degeneration.

Aging, chronic oxidative stress, and inflammation are major pathogenic factors in the development and progression of age-related macular degeneration (AMD) with the loss of retinal pigment epithelium (RPE). The human RPE contains a subpopulation of progenitors (i.e., RPE stem cells-RPESCs) whose role in the RPE homeostasis is under investigation. We evaluated the paracrine effects of mature RPE cells exposed to oxidative stress (H2O2) on RPESCs behavior through co-cultural, morphofunctional, and bioinformatic approaches. RPESCs showed a decline in proliferation, an increase of the senescence-associated ß-galactosidase activity, the acquisition of a senescent-like secretory phenotype (SASP), and the reduction of their stemness and differentiation competencies. IL-6 and Superoxide Dismutase 2 (SOD2) seem to be key molecules in RPESCs response to oxidative stress. Our results get insight into stress-induced senescent-associated molecular mechanisms implicated in AMD pathogenesis. The presence of chronic oxidative stress in the microenvironment reduces the RPESCs abilities, inducing and/or maintaining a pro-inflammatory retinal milieu that in turn could affect AMD onset and progression.

Intraocular Pressure Rise Linked to Silicone Oil in Retinal Surgery: A Review.

Silicone oil represents the main choice for intraocular tamponade in cases of complicated retinal detachment surgery. The intraocular pressure of an eye filled with silicone oil could increase, driven by a variety of different forces, according to several mechanisms. Two main conditions have been highlighted, depending on the onset: early hypertension or late glaucoma. The different types of silicone oils and their physico-chemical properties are varied and may play a role in the determination of intraocular pressure rise. The current body of literature allows for the illustration and categorization of the incidence and risk factors, as well as the pathogenesis and the management of the early postoperative hypertension subtended by an open- and closed-angle, along with the late onset silicone oil-induced glaucoma. Understanding the leading actors on the stage of ocular pressure elevation concurrently with silicone oil application for retinal surgery could help in guiding the timely and appropriate course of treatment.

EX-PRESS Glaucoma Filtration Device: Management of Complications.

The EX-PRESS glaucoma filtration device appears to be an effective addition to our options to treat refractory glaucoma. The possibility to create a sclerostomy without tissue excision provides a safe and reliable outflow pathway for aqueous that is standard in size, reducing much of the variability associated with a surgical procedure. Prospective randomized studies comparing EX-PRESS implantation with trabeculectomy show encouraging results. However, complications usually encountered in filtration surgery have been reported, and EX-PRESS implantation can also lead to specific device-related complications. This article reviews the most common complications associated with this procedure.

Photodynamic therapy and subthreshold micropulse laser treatment - A novel combined approach for the treatment of serous retinal detachment in dome-shaped macula.

Dome-shaped macula (DSM) is characterized by an inward convexity of the macula in myopic eyes, as visualized on optical coherence tomography (OCT). Serous retinal detachment (SRD) is a common complication of DSM, leading to a deterioration of visual acuity, in association with retinal pigment epithelium (RPE) atrophic changes. Many different therapeutic approaches to SRD secondary to DSM have been attempted, with variable results. We report our experience (11 treatment-naïve patients) with a combined new treatment approach, using half-fluence and half-dose photodynamic therapy (PDT) followed by subthreshold 577 nm micropulse laser treatment (STLT), for SRD related to DSM after a 6-month follow-up. Central foveal thickness was significantly decreased at the end of the follow-up. SRD diminished in all cases, and 5 eyes (45.4 %) registered complete resolution at the end of the 6-month follow-up, while 6 eyes (54.5 %) experienced two lines of improvement in BCVA at the end of the follow-up. No case showed postoperative complications. Therefore, this represents the first study evaluating the visual and anatomical outcomes of a safe and effective combined treatment of SRD in DSM.

Long-term improvement of retinal sensitivity after macular hole surgery over at least 9-year-old follow-up: a case series.

PURPOSE: To evaluate the correlations between anatomical and functional changes in idiopathic macular hole (IMH) surgery in long-term follow-up. METHODS: This is a prospective, interventional single centre case series. The final sample is formed by 14 eyes of 14 patients who had undergone IMH surgery in our institution between 2005 and 2009 and were still followed up in 2019. Reported data were pre- and post-operative best-corrected visual acuity (BCVA), retinal sensitivity and fixation stability values on MP-1 and structural macular features on spectral domain optical coherence tomography. Optical coherence tomography angiography (OCTA) was utilized to assess microvascular characteristics at the final visit. Only patients with a successful MH closure were enrolled, excluding eyes affected by other relevant pathologies. RESULTS: Mean BCVA improvement was significant after surgery (t test, p value < 0.001) and presented a slight, not statistically significant raise, between the post-operative and long-term follow-up. Differently, mean retinal sensibility (dB) showed a highly statistically significant difference between pre-operative and post-operative (t test, p value = .002) and post-operative and last follow-up (p value < 0.001). In the long-term follow-up, subjects having integrity of the inner segment/outer segment (IS/OS) layer showed no statistically significant difference in BCVA compared with subjects with IS/OS discontinuity (t test, p value = 0.72). OCTA parameters of the operated eye showed no statistical significance compared with the fellow eye. CONCLUSIONS: In successfully closed MHs, retinal sensibility measured by microperimetry significatively increases after a long follow-up period even when BCVA remains stable or raises slightly. Vessel density organization tends to be quantitatively similar to fellow eye several years after surgery.

Intraocular Inflammation Control and Changes in Retinal and Choroidal Architecture in Refractory Non-Infectious Uveitis Patients after Adalimumab Therapy.

Background: Non-infectious uveitis represents a leading cause of visual impairment, and inflammation control represents a major priority in tackling visual acuity loss due to complications such as macular edema; different immunomodulatory drugs are currently being used, including anti-TNF-alpha Adalimumab. Methods: This was a monocentric observational study of 18 eyes of 18 patients with non-infectious uveitis treated with Adalimumab. The primary endpoint was the control of ocular inflammation. The secondary endpoints included the study of macular and choroidal thickness and architecture, visual acuity, changes in other treatments, and adverse effects. Results: Ocular inflammation was controlled at 12 months for 83.3% of patients. Central macular thickness improved from a median of 229.75 µm at baseline to 213 µm at 12 months, while choroidal thickness decreased by 11.54% at the end of the follow-up. A reduction of vasculitis on fluorescein angiography and of hyperreflective spots on optical coherence tomography was noted. Visual acuity also improved from 0.51 (logMAR) before treatment to 0.24 at more than 12 months (p = 0.01). A total of 11.1% of patients experienced side effects. Conclusion: Our study confirms the efficacy of adalimumab for the control of ocular inflammation, visual acuity preservation, and for corticosteroid sparing.

Papillary Vessel Density Changes After Intravitreal Anti-VEGF Injections in Hypertensive Patients with Central Retinal Vein Occlusion: An Angio-OCT Study.

PURPOSE: To investigate papillary microvascular changes in patients affected by macular edema due to Central Retinal Vein Occlusions (CRVO) after anti-Vascular Endothelial Growth Factor (VEGF) therapy. METHODS: Prospective analysis of papillary and peripapillary vessel density (VD) changes in 18 eyes of 18 hypertensive patients affected by CRVO before and after the loading-phase of intravitreal Ranibizumab (IVR) injections. Data were quantitatively measured by optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) before as well as 1 month and 4 months after injections. The correlation between post-treatment best-corrected visual acuity (BCVA) and changes in the retinal microvasculature evaluated by OCTA was assessed. Results: 18 eyes of 18 consecutive patients with a known history of arterial hypertension and affected by an acute CRVO episode were enrolled. Central macular thickness (CMT) was significantly reduced after IVR injections (p < 0.001), while mean BCVA improved from 0.70 ± 0.26 logarithm of the minimal angle of resolution (logMAR) units at baseline to 0.25 ± 0.18 logMAR units after 4 months (p < 0.001). VD inside disc and peripapillary significantly increased (p < 0.001 and p = 0.01, respectively) after treatment. CONCLUSIONS: OCTA showed VD increase in the papillary area in patients affected by CRVO after anti-VEGF therapy. This area could represent a new region of interest to study microvasculature changes concomitant with severe macular edema.

The Eye as a Window to Systemic Infectious Diseases: Old Enemies, New Imaging.

BACKGROUND: Syphilis, tuberculosis and toxoplasmosis are major infectious diseases worldwide; all of them are multisystem pathologies and share a possible ocular involvement. In this context, a fundamental help for the definitive diagnosis is provided by the ophthalmologist, through clinical evaluation and with the aid of a multimodal imaging examination. METHODS: We hereby describe selected cases who came to our attention and were visited in our eye clinic. In all clinics, the use of retinal and optic disc multimodal imaging during ophthalmological evaluation allowed to make a diagnosis of an infectious disease. RESULTS: In our tertiary referral center more than 60 patients with syphilis, tuberculosis and toxoplasmosis have been evaluated in the last two years: In 60% of cases the ophthalmological evaluation was secondary to a previous diagnosis of an infectious disease, while in the remaining cases the ophthalmologist, with the help of a multimodal imaging examination and clinical evaluation, represented the physician who leads to the diagnosis. CONCLUSION: Our results confirm how in these life-threatening pathologies a prompt diagnosis is mandatory and may benefit from a multidisciplinary and multimodal imaging approach, especially during ophthalmological evaluation.

Effects of senescent secretory phenotype acquisition on human retinal pigment epithelial stem cells.

Regenerative medicine approaches based on mesenchymal stem cells (MSCs) are being investigated to treat several aging-associated diseases, including age-related macular degeneration (AMD). Loss of retinal pigment epithelium (RPE) cells occurs early in AMD, and their transplant has the potential to slow disease progression.The human RPE contains a subpopulation of cells - adult RPE stem cells (RPESCs) - that are capable of self-renewal and of differentiating into RPE cells in vitro. However, age-related MSC changes involve loss of function and acquisition of a senescence-associated secretory phenotype (SASP), which can contribute to the maintenance of a chronic state of low-grade inflammation in tissues and organs.In a previous study we isolated, characterized, and differentiated RPESCs. Here, we induced replicative senescence in RPESCs and tested their acquisition of the senescence phenotype and the SASP as well as the differentiation ability of young and senescent RPESCs.Senescent RPESCs showed a significantly reduced proliferation ability, high senescence-associated ß-galactosidase activity, and SASP acquisition. RPE-specific genes were downregulated and p21 and p53 protein expression was upregulated.These findings document the effects of senescence and SASP acquisition on RPESC differentiation ability and highlight the need for a greater understanding of their role in AMD pathogenesis.

Negative staining of the vitreous with the use of vital dyes.

PURPOSE: The vitreous cortex, epiretinal membrane (ERM), and inner limiting membrane (ILM) are transparent tissues and are thus difficult to visualize. Staining these structures can increase the efficiency of a nontraumatic removal. METHODS: The surgeon performs a partial core vitrectomy and induces a posterior vitreous detachment. The vital dye is then injected into the retrohyaloid space in balanced salt solution (BSS). The dyes used are TWIN (Alchimia srl, Padova, Italy), MembraneBlue-Dual (DORC International, Zuidland, the Netherlands), and Doubledyne (Alfa Intes, Casoria, Italy). The surgeon can complete the vitrectomy and gradually aspirate the dye with the probe. Once the vitrectomy is complete, the surgeon can perform the peeling of the ERM without the need to reinject the vital dye over the macula. RESULTS: The presence of the dye over the macula facilitates visualization of the vitreous cortex by blocking the red reflex and increasing the contrast power of the coaxial light probe during the vitrectomy. This allows a negative coloration of the vitreous because the dye acts by increasing the visibility of the surrounding BSS and not the vitreous itself. CONCLUSIONS: We describe a new chromovitrectomy technique using the same dye to increase the visualization of the vitreous, posterior hyaloid, ERM, and ILM.

Primary Vaginal Calculus in a Woman with Disability: Case Report and Literature Review.

Background: Vaginal stones are rare and often unknown entities. Most urologists may never see a case in their careers. Case Presentation: We present the case of a 34-year-old bedridden Caucasian woman with mental and physical disabilities who presented with a large primary vaginal calculus, which, surprisingly, had remained undiagnosed until the patient suffered a right renal colic caused by a ureteral stone. The vagina was completely filled and a digital examination was not possible. For this reason, the stone was removed using surgical pliers with some maneuvering. A vesicovaginal fistula was excluded, as well as foreign bodies or other nidi of infection. After, urethral lithotripsy was performed as planned. The postoperative course and follow-up were uneventful. Conclusion: Although vaginal calculi are extremely rare in literature, their differential diagnosis should be considered in women with incontinence and associated disabilities, paraplegia, or prolonged immobilization in recumbent position.
