RESUMO

Few cases of isolated spontaneous hyphema in the newborn have been reported. A case of a term vaginally delivered female newborn who was diagnosed as having a hyphema in the left eye 18 hours after birth is presented. Delivery was complicated with fetal head malposition and the delivery was prolonged. The mother was nulliparous and without significant medical history. The hyphema resolved within 3 days without complications or sequela. The authors review the literature of spontaneous newborn hyphema and link an association with fetal head malposition.

RESUMO

PURPOSE: To describe the in toto explantation of the CyPass® Micro-Stent and its conceivable complications. METHODS: This is a case series of eighteen eyes from fourteen patients who underwent CyPass® Micro-Stent implantation due to mild to moderate glaucoma and who subsequently suffered from loss of endothelial cell density. Consequently, the CyPass® Micro-Stent was in toto explanted. The surgical procedure and its complications are described and compared with trimming of the CyPass® Micro-Stent. RESULTS: A postoperative hyphema was developed in 8 of the 18 eyes. In four of them the hyphema was self-limiting, while in two patients an anterior chamber irrigation was necessary. One patient suffered from a severe intracameral bleeding and iridodialysis during explantation, so that the base of the iris had to be scleral fixated. The remaining explantations were without complications. CONCLUSION: Dealing with implanted CyPass® Micro-Stents poses a challenge for ophthalmic surgeons. An in toto removal can be traumatic, since the CyPass stent often is fibrotic encapsulated and fused with the surrounding tissue. Alternatively, trimming of the CyPass is also a viable option to avoid further endothelial damage. Reported complications of CyPass trimming are consistent with those that can occur after explantation. Further data on the development of the endothelial cells after trimming or explantation are not yet available. Therefore, it remains open whether trimming of the CyPass, in contrast to complete removal, carries the risk of further endothelial cell loss.

RESUMO

Objectives: To evaluate the demographic, etiological, and accompanying clinical factors in eyelid lacerations (EL). Materials and Methods: The records of patients who presented to our clinic between 2018 and 2022 with eyelid trauma were retrospectively reviewed. Age, gender, cause of injury, clinical findings, accompanying ocular findings, and additional complications were analyzed. Results: The study included 135 patients (106 male, 29 female) with a mean age of 37.0±18.6 years. Among the patients, 29 (21.4%) were 18 years old or younger, 93 (68.8%) were between 19 and 64 years old, and 13 (9.6%) were 65 years old or older. EL were most caused by various sharp objects in 44 patients (33%), blunt trauma in 40 patients (30%), falls in 30 patients (22%), and traffic accidents in 21 patients (15%). Fifteen eyes (11.1%) had foreign bodies at the wound site. Thirty patients (22.2%) (20 lower eyelid, 10 upper eyelid) had accompanying canalicular lacerations. Twenty-three (17%) patients had accompanying conjunctival lacerations, 14 (10.3%) had open-globe injury, 10 (7.4%) had corneal epithelial defects, 9 (6.6%) had intravitreal hemorrhage, 6 (4.4%) had hyphema, and 5 (3.7%) had retinal detachment. Four patients had lid notching and 1 patient (0.7%) had ectropion. Five patients (3.7%) required suturing. No additional complications were observed. Conclusion: EL are more commonly seen in young adulthood and in males. The most common mechanism of injury is impact by various objects. Eyelash margin and canalicular lacerations frequently accompany these injuries. Serious ocular pathologies such as hyphema and open-globe injury can accompany eyelid trauma.

RESUMO

We present a case of primary rhabdoid tumour of the orbit. Presenting features at birth included congenital ptosis, conjunctival injection, hyphaema and microphthalmia. The unique presentation caused a late diagnosis following the development of rapid proptosis 6 months later. We suggest that orbital rhabdoid tumour be considered in the differential diagnoses of patients presenting with atypical persistent foetal vasculature features.

RESUMO

Uveitis-Glaucoma-Hyphema (UGH) syndrome is characterized by episodes of anterior chamber inflammation, elevated intraocular pressure and hyphema. It is caused by a mechanical chafing of the iris or ciliary body typically by a malpositioned intraocular lens. We present a rare case of UGH syndrome related to the insertion of a Hydrus Microstent. Because of the increased number of microinvasive glaucoma surgeries being performed and a reduction of UGH syndrome patients related to the insertion of intraocular lenses, it is an important diagnosis to consider in patients with recurrent postoperative inflammation.

RESUMO

PURPOSE: To assess the safety and efficacy of combining phacoemulsification with gonioscopy-assisted transluminal trabeculotomy (GATT) compared to phacoemulsification alone in the management of primary angle closure glaucoma (PACG). METHODS: Prospective, institutional study in which eyes requiring surgery for PACG were randomized to undergo phacoemulsification followed by GATT (phaco-GATT group) or phacoemulsification alone. Success was defined as having a final IOP of 6-20 mmHg with no subsequent glaucoma surgery or vision-threatening complications. RESULTS: Thirty-six eyes underwent phaco-GATT with 360° angle incision and 38 eyes underwent phacoemulsification alone. IOP and glaucoma medications were significantly lower in the phaco-GATT group at 1, 3, 6, 9 and 12 months. The success rate in the phaco-GATT group was 94.4% after 12.16 ± 2.03 months, with 75% of eyes being off medications compared to 86.8% after 12.47 ± 4.27 months in the phaco group, with 42.1% off medications. (p = 0.008). Hyphema and fibrinous anterior chamber reaction were the most common complications in the phaco-GATT group and resolved with conservative treatment or required YAG capsulotomy. Although this delayed visual rehabilitation in the phaco-GATT group, it did not affect the final visual outcome with no significant difference in the final best-corrected visual acuity between both groups (p = 0.25). CONCLUSION: Combining phacoemulsification with GATT in PACG yielded more favourable outcomes in terms of IOP, glaucoma medications and surgical success. Although the postoperative hyphema and fibrinous reaction may delay visual rehabilitation, GATT further lowers the IOP by breaking residual peripheral anterior synechiae and removing the dysfunctional trabeculum circumferentially, while avoiding the risks inherent in more invasive filtering procedures.

RESUMO

PURPOSE: To examine the clinical characteristics of patients who have experienced blunt ocular injuries from "Orbeez" hydrated gel pellets (Spin Master Corp.), and to describe ocular morbidity, visual acuity (VA), and intraocular pressure (IOP) after Orbeez-related ocular trauma. DESIGN: Retrospective, institutional, observational case series. METHODS: Patients sustaining Orbeez-related ocular trauma at a single institution over a 13-month period were identified. Clinical parameters including VA, IOP, and anterior and fundus examination findings were assessed upon initial and final presentation. Basic statistical testing was performed to compare differences within this cohort. RESULTS: A total of 17 eyes from 17 patients with Orbeez-related trauma were identified. Orbeez-related blunt ocular injuries included corneal abrasion (n = 7), hyphema (n = 9), commotio retinae (n = 5), intraretinal hemorrhage (n = 3), preretinal hemorrhage (n = 1), vitreous hemorrhage (n = 2), and retinal tear (n = 1). Adolescents (14-18 years of age) showed higher rates of posterior segment complications compared to other ages (P = .0152). The presence of elevated IOP and hyphema upon initial examination correlated with increased likelihood of requiring invasive treatment following Orbeez impact (P = .0275). CONCLUSION: Orbeez-related ocular trauma may be associated with severe visual morbidity and varied anterior and posterior segment intraocular sequelae. Adolescents could be at increased risk for posterior segment complications following these injuries. Initial findings of elevated IOP and hyphema may indicate a need for more aggressive interventions. Prevention remains paramount in managing Orbeez-related ocular trauma; it is critical to raise awareness regarding the importance of wearing eye protection meeting high-impact standards and minimizing exposure to such projectiles.

RESUMO

PURPOSE: Minimally invasive glaucoma surgery is safer and effective surgical modality for patients with glaucoma. To compare the effect of axial length (AL) on the surgical outcomes of combined cataract surgery and ab interno trabeculotomy (phaco-LOT), a retrospective, non-randomized comparative study was performed. METHODS: In total, 458 eyes of 458 open-angle glaucoma patients who underwent phaco-LOT and were followed-up without any intervention for at least 6 months were enrolled. All were divided into a long-AL group (AL ≥ 26.0 mm, 123 eyes) and a not-long-AL group (AL < 26.0 mm, 335 eyes). The principal outcomes were the changes in intraocular pressure (IOP) and medication scores. We also sought a correlation between postoperative IOP spike and hyphema. RESULTS: Significant postoperative reductions in IOP and medication scores were apparent in all subjects. The IOP reductions were significant at all timepoints in the not-long-AL group, but not until 1 month postoperatively in the long-AL group, and the IOP change was significantly lower in the long-AL group from postoperative day 1 to 3 months. On subanalysis of subjects by age, the microhook used, the pre-operative IOP, and the medication score, a significantly higher incidence of IOP spike was observed in the long-AL group in weeks 1 and 2 (both p < 0.05), but this did not correlate with hyphema status, implying that a different mechanism was in play. CONCLUSION: Phaco-LOT was effective regardless of AL, but the postoperative IOP decrease was lower and the early postoperative incidence of IOP spike was higher in long-AL eyes.

RESUMO

Filtration surgery (Trabeculectomy) is the main treatment for glaucoma. The scarring of the filtration bleb and obstruction of the outflow of aqueous humor through the filtration channel are the main reasons of the surgery failure. The objective of this study was to determine the clinical efficacy of needle revision of filtration blebs combined with subconjunctival injection of conbercept on the functional bleb formation in glaucoma patients with eye pressure out of control after trabeculectomy. A total of 48 eyes with poor filtration bleb function after trabeculectomy for glaucoma were treated with needle revision of filtration bleb combined with subconjunctival injection of conbercept. After the treatment, the patients were followed up for 3 months during which visual acuity, intraocular pressure, slit lamp and ultrasound biomicroscope examinations were performed. Intraoperative and postoperative complications were recorded. The visual acuity and intraocular pressure were significantly improved after the needle revision of filtration blebs. Among the 48 eyes, 39 eyes still had functional blebs at the end of the follow-up period, and filtration blebs failed in 9 eyes 2 to 8 weeks after the removal of the needle. The survival rate of filtration blebs at 3 months after needle revision was (79.06 ±â€…3.42%), and 81.25% (39/48) of the eyes showed good formation rate of functional bleb at the last follow-up. Three months after needle revision, there was local scar formation in some filtration blebs. Part of the filtration blebs showed mild thickening of the local subconjunctival tissue, and the filtration bleb was slightly raised and diffuse, showing a multi-cavity and thin-walled shape in some blebs. Ultrasound biomicroscopy examination showed relative structural manifestations. Subconjunctival hemorrhage occurred in 43 patients during and after the operation. Low intraocular pressure occurred in 8 patients with the lowest pressure of 5 mm Hg. Choroidal edema was observed in 3 patients. Five patients had intraoperative conjunctival hemorrhage in the anterior chamber, and hyphema occurred. All complications were self-limited and resolved without surgical intervention. Needle revision of filtration bleb combined with anti-VEGF drugs is a safe and effective method for the treatment of filtration bleb dysfunction after surgery of glaucoma.

RESUMO

PURPOSE: To compare the efficacy and safety of 120-, 240-, and 360-degree goniotomy (GT) with or without phacoemulsification with intraocular lens implantation (PEI) for patients with primary open-angle glaucoma (POAG). DESIGN: Multicenter, retrospective, comparative, nonrandomized interventional study. METHODS: Patients diagnosed with POAG who underwent GT with or without PEI were included, and divided into 6 groups: 1) standalone 120-degree GT (120GT); 2) standalone 240-degree GT (240GT); 3) standalone 360-degree GT (360GT); 4) PEI + 120GT; 5) PEI + 240GT; and 6) PEI + 360GT. Data on intraocular pressure (IOP), the number of ocular hypotensive medications, and complications were collected and compared. Success was defined as a postoperative IOP within the range of 6 to 18 mm Hg and a 20% reduction from baseline without further glaucoma surgery. Complete success and qualified success were defined as the above without and with ocular hypotensive medications, respectively. RESULTS: Three hundred eight eyes of 231 patients were included with a mean follow-up of 14.4 ± 8.6 months (6.0-48.0 months). There were no significant differences in the reductions in IOP and number of medications and cumulative survival probability for complete and qualified success rates among the 3 groups of standalone GT and PEI + GT. The 360GT group had the highest proportion of hyphema with or without PEI. CONCLUSIONS: 120GT, 240GT, and 360GT with or without PEI showed similar efficacy in reducing IOP and medications used in POAG. 360GT with or without PEI was more likely to cause hyphema compared with 120GT or 240GT. 120GT with or without PEI was sufficient for treating POAG with or without cataract..

RESUMO

BACKGROUND: Traumatic aniridia occurs when the iris is extruded from the eye and is often accompanied by lens injuries. However, traumatic aniridia due to dislocation of the iris into the vitreous cavity without lens damage has never been reported. CASE PRESENTATION: A 30-year-old man presented with visual loss and pain for 6 h after a thin wire injured his right eyeball. Ophthalmologic examinations manifested a 2 mm full-thickness corneal laceration and total hyphema. An intact clear lens, healthy attached retina, and almost complete iris tissue in the vitreous cavity were found after resolution of hyphema the next day. Further examination revealed that the defect in the zonule below the corneal wound was the path for the iris to enter the vitreous cavity. The patient opted for nonsurgical treatment until pigment granules and opacity were observed in the vitreous cavity after 50 days. Vitrectomy was performed to remove the dislocated iris. CONCLUSIONS: The presentation of this unique case indicates that the torn iris was displaced to the vitreous cavity with an intact lens and missing local zonula instead of out the corneal laceration after a penetrating injury. The type of injury, mechanism, and force on the spot may contribute to the occurrence of this rare condition. Instead of artificial irises, tinted glasses were more appropriate treatment option for this patient. Peripheral retinal examination was essential in the management of this case. In such cases, the iris in the vitreous cavity should be resected to prevent complications.

RESUMO

A 4-year-old mixed-breed dog was presented for hyphema and glaucoma of the right eye. Enucleation of the right globe was carried out, and histopathology examination revealed an optic nerve glioma with incomplete surgical margins. At 8 wk after surgery, the dog had depressed mentation and a diminished pupillary light reflex of the left eye. Magnetic resonance imaging revealed an irregular, heterogeneously T2 hyperintense/T1 isointense mass in the region of the optic chiasm. Compression of the rostral thalamus was present, with effacement of the pituitary gland and involvement of the right orbit. The dog was euthanized 4.5 mo after initial presentation. An undefined glioma of the right optic nerve with extension to the diencephalon was diagnosed on necropsy. Key clinical message: Although rare, intraocular glioma is a differential diagnosis for hyphema, glaucoma, and retinal detachment. Magnetic resonance imaging should be considered in cases of intraocular neoplasia, notably in those with incomplete surgical margins of the optic nerve.


Description clinique avec aspect en résonance magnétique d'un gliome indéfini de haut grade du nerf optique avec extension intracrânienne. Un chien de race croisé âgé de 4 ans a été présenté pour un hyphéma et un glaucome de l'œil droit. Une énucléation du globe droit a été réalisée et l'examen histopathologique a révélé un gliome du nerf optique aux marges chirurgicales incomplètes. Huit semaines après la chirurgie, le chien avait une diminution du processus mental et un réflexe pupillaire à la lumière diminué de l'œil gauche. L'imagerie par résonance magnétique a révélé une masse irrégulière hétérogène hyperintense T2/T1 isointense dans la région du chiasma optique. Une compression du thalamus rostral était présente, avec effacement de l'hypophyse et atteinte de l'orbite droite. Le chien a été euthanasié 4,5 mois après la présentation initiale. Un gliome indéfini du nerf optique droit avec extension au diencéphale a été diagnostiqué à l'autopsie.Message clinique clé:Bien que rare, le gliome intraoculaire est un diagnostic différentiel pour l'hyphéma, le glaucome et le décollement de la rétine. L'imagerie par résonance magnétique doit être envisagée en cas de néoplasie intraoculaire, notamment chez ceux dont les marges chirurgicales du nerf optique sont incomplètes.(Traduit par Dr Serge Messier).

RESUMO

BACKGROUND: To evaluate retinal and choroidal vascular changes in cases with hyphema after blunt ocular trauma that did not cause globe rupture or any retinal pathology. METHODS: This cross-sectional study included 29 patients who developed hyphema after unilateral blunt ocular trauma (BOT). The other healthy eyes of the same patients were evaluated as the control group. Optical coherence tomography-angiography (OCT-A) was used for imaging. In addition, choroidal parameters were compared by calculating the choroidal vascular index (CVI) and using choroidal thickness measurements by two independent researchers. RESULTS: Superior and deep flow values were significantly decreased in the traumatic hyphema group compared to the control group (p<0.05). Parafoveal deep vascular density (parafoveal dVD) values were decreased in traumatized eyes compared to control eyes (p=0.000). Vascular density values were similar other than that. In addition, there was a significant decrease in optic disc blood flow (ODF) and optic nerve head density (ONHD) values compared to the control group (p<0.05). In addition, no significant difference was observed between the groups in terms of mean CVI values (p>0.05). CONCLUSION: Non-invasive diagnostic tools such as OCTA and EDI-OCT can be used to detect and monitor early changes in retinal and choroidal microvascular flow in cases of traumatic hyphema.

RESUMO

PURPOSE: To investigate the anti-inflammatory and anti-angiogenic effects of the bioactive lipid mediator LXA4 on a rat model of severe corneal alkali injury. METHODS: To induce a corneal alkali injury in the right eyes of anesthetized Sprague Dawley rats. They were injured with a Φ 4 mm filter paper disc soaked in 1 N NaOH placed on the center of the cornea. After injury, the rats were treated topically with LXA4 (65 ng/20 µL) or vehicle three times a day for 14 days. Corneal opacity, neovascularization (NV), and hyphema were recorded and evaluated in a blind manner. Pro-inflammatory cytokine expression and genes involved in cornel repair were assayed by RNA sequencing and capillary Western blot. Cornea cell infiltration and monocytes isolated from the blood were analyzed by immunofluorescence and by flow cytometry. RESULTS: Topical treatment with LXA4 for two weeks significantly reduced corneal opacity, NV, and hyphema compared to the vehicle treatment. RNA-seq and Western blot results showed that LXA4 decreased the gene and protein expression of pro-inflammatory cytokines interleukin (IL)-1ß and IL-6 and pro-angiogenic mediators matrix metalloproteinase (MMP)-9 and vascular endothelial growth factor (VEGFA). It also induces genes involved in keratinization and ErbB signaling and downregulates immune pathways to stimulate wound healing. Flow cytometry and immunohistochemistry showed significantly less infiltration of neutrophils in the corneas treated with LXA4 compared to vehicle treatment. It also revealed that LXA4 treatment increases the proportion of type 2 macrophages (M2) compared to M1 in blood-isolated monocytes. CONCLUSIONS: LXA4 decreases corneal inflammation and NV induced by a strong alkali burn. Its mechanism of action includes inhibition of inflammatory leukocyte infiltration, reduction in cytokine release, suppression of angiogenic factors, and promotion of corneal repair gene expression and macrophage polarization in blood from alkali burn corneas. LXA4 has potential as a therapeutic candidate for severe corneal chemical injuries.

RESUMO

BACKGROUND: To evaluate anterior segment optical coherence tomography (AS-OCT) data in patients with unilateral blunt ocular trauma (BOT), to determine the relationship of results with hyphema development. METHODS: 21 patients who received unilateral BOT were included in the study. Healthy eyes of patients were included in the control group. Iris stromal thickness (IST), schlemm canal area (SCA) and pupil diameter were measured by AS-OCT of the participants. In addition, eyes with ocular trauma were divided into those with and without hyphema and compared in terms of these parameters. RESULTS: The mean nasal and temporal (n-t) IST was measured as 373± 40 µm and 369 ± 35 µm in BOT in comparison with 344 ± 35 µm and 335 ± 36 µm in control eyes, respectively (p = 0.000 and p = 0.001, respectively). The mean nasal and temporal (n-t) SCA was measured as 12,571 ± 880 µm2 and 12,162 ± 1181 µm2 in developed hyphema in comparison with 10,455 ± 1506 µm2 and 10,188 ± 939 µm2 in did not develop hyphema, respectively (p = 0.016 and p = 0.002 respectively). CONCLUSION: The ISTs of the traumatized eyes in the nasal and temporal quadrants were statistically thicker than the other healthy eyes. SCA in both nasal and temporal quadrants of eyes with hyphema was statistically significantly larger than the group without hyphema.

RESUMO

PRCIS: Goniotomy (GT) 120 degrees with or without phacoemulsification was sufficient to lower the intraocular pressure (IOP) and reduce hyphema for primary open angle glaucoma. PURPOSE: To compare the surgical outcomes and safety profiles of 120 degrees and 360 degrees GT with or without phacoemulsification cataract extraction and intraocular lens implantation (PEI) for primary open angle glaucoma. PATIENTS AND METHODS: This multicenter retrospective study consisted of 139 eyes and was divided into 4 groups: (1) 120 degrees GT, (2) 360 degrees GT, (3) PEI + 120 degrees GT, and (4) PEI + 360 degrees GT. IOP, number of topical hypotensive medications, and complications were recorded and evaluated at baseline and at the final visit. The complete and qualified success rate and their potential associated factors were also investigated. The effectiveness and safety profile of the surgery were compared between different subgroups. RESULTS: After a mean follow-up of 8.6 months, the IOP reduction was 13.2 ± 8.3 (38.8 ± 28.8%), 12.4 ± 8.3 (41.6 ± 18.2%), 12.8 ± 9.9 (39.4 ± 34.5%), and 13.8 ± 7.2 (46.0±17.1%) mm Hg in 120 degrees, 360 degrees, PEI + 120 degrees GT group, and PEI + 360 degrees GT, respectively. No significant difference was found in IOP, a decline of IOP from baseline, topical hypotensive medication, and complete or qualified success between either standalone 120 degrees versus 360 degrees GT, or PEI + 120 degrees versus PEI + 360 degrees GT (all P s > 0.05). The PEI + 120 degrees GT group had a lower final IOP than the 120 degrees GT group ( P = 0.0002) whereas there was no difference between PEI + 360 degrees GT and 360 degrees GT group ( P = 0.893). Both 360 degrees GT and PEI + 360 degrees GT group had a significantly higher incidence of hyphema than the 120 degrees GT and PEI + 120 degrees GT groups (all P s < 0.0001). CONCLUSIONS: GT of 120 or 360 degrees lowered IOP equally with or without cataract surgery, and hyphema was most commonly noted after complete GT. Partial GT alone or in combination with cataract surgery was an effective and safe approach to manage patients with open angle glaucoma.
