RESUMO
To report clinical outcomes following ocular injury from foam dart (nerf) blasters - a spring-loaded toy guns that fire foam-coated darts or bullets at a relatively low velocity. These guns gained popularity in recent years among children and adolescents. Eleven patients with ocular injuries from foam dart blasters were included in this retrospective, single-center study. Visual acuity (VA), intraocular pressure (IOP), and anterior segment, glaucoma-related, and vitreoretinal complications were recorded at each visit. The average age at presentation was 13.4 years and 82% were male. Mean initial VA was 6/12 (range 6/6 - 1/18); On initial examination, nine patients (82%) had hyphema, three (27%) had corneal abrasions, three (27%) had vitreous hemorrhage, and two (18%) had traumatic mydriasis. Four patients (36%) experienced glaucoma-related complications, including three (27%) with angle recession and three (27%) with increased IOP. Three patients (27%) were diagnosed with posterior segment injuries, including three (27%) with commotio retinae and one (9%) with severe retinal photoreceptor damage. No patients required surgical intervention. CONCLUSION: Foam dart blasters can cause severe blunt ocular trauma and permanent visual loss, illustrating the need for eye protection when handling these toys. WHAT IS KNOWN: ⢠Foam dart blasters, a blanket term for spring-loaded toy guns that fire foam-coated darts or bullets at a relatively low velocity, have gained popularity in recent years among pediatric populations, with an increase in associated ocular injuries. ⢠To date, scattered case reporting provides insufficient insight into the full clinical spectrum of injury and prognosis of foam dart blasters related ocular injury. WHAT IS NEW: ⢠This case series characterizes the myriad foam dart blasters injuries that may afflict the eye, most of which are self-limiting, but some of which may result in poor visual outcomes and lifelong disability in pediatric patients. ⢠We strongly recommend that all users wear eye protection while using foam dart blasters.

PURPOSE: To highlight the efficacy of primary Ahmed glaucoma valve implantation in angle recession glaucoma following blunt ocular trauma in Indian eyes. DESIGN: A retrospective analytical study. MATERIALS AND METHODS: This study included 52 patients of angle recession glaucoma, who presented between Mar 2006 to Feb 2016, out of which 38 patients had undergone primary AGV implantation, while the rest were managed with topical anti-glaucoma medications. Preoperative data included age, sex, type and mode of injury, duration of injury, assessment of best-corrected visual acuity (BCVA) and intraocular pressure (IOP). The extent of angle recession was observed by gonioscopy. The intraocular pressure, visual acuity, and the number of anti-glaucoma medications were measured postoperatively. The success of this technique was analyzed by using a Kaplan-Meier cumulative survival curve. RESULTS: Following AGV implantation, the mean IOP was significantly reduced to 8.7 ± 2.2 at 1st day, 10.1 ± 2.2 at 7th day, 14.2 ± 3.4 at 3rd month, 15.6 ± 3.7 at 1 year, and 15.6 ± 3.6 at 3rd-year follow-up showing statistically significant values (p < 0.001) at each visit. The IOP was successfully controlled at the last follow-up without topical treatment. Mean BCVA at 3 years -post-AGV was 0.144 (0.151) (LogMAR) which was statistically significant (p < 0.001) as compared to the mean BCVA of 0.898 (± 0.205) LogMAR units at presentation. The success rate by Kaplan-Meier survival curve analysis was 90% at the mean follow-up duration of 29.47 ± 3.39 months. Overall surgical complications were noted in the form of prolonged hypotony, hyphema in 7 patients (13.5%). CONCLUSIONS: In medically uncontrolled post-traumatic angle recession glaucoma, primary AGV Implantation is a safe and effective surgical procedure with lesser complication rates providing long-term IOP control in a younger population.

This study aims to determine the incidence of angle recession and glaucoma after traumatic microhyphema. Records of all patients treated for traumatic hyphema or microhyphema admitted to a district hospital throughout a 10-year period were retrospectively reviewed. Patients with open-globe injury were excluded. The following clinical features were recorded during patients' initial presentation and follow-up visits: Snellen visual acuity, examination with slit-lamp biomicroscopy, intraocular pressure (IOP), dilated fundoscopic examination, gonioscopic examination and treatment. For patients with IOP > 21 mmHg and requiring glaucoma medications, visual field tests were performed. A total of 97 patients met the study criteria, of which 62 had microhyphema and 35 had gross hyphema. Among the traumatic microhyphema patients, 47 (75.8 %) had angle recession and 4 (6.5 %) had glaucoma with mean follow-up of 49 months (range 6-98 months). A statistically significant association was found between angle recession greater than 180° and the occurrence of glaucoma (p < 0.01). No statistically significant differences were found between groups of patients with microhyphema or gross hyphema regarding the incidence of angle recession and glaucoma. The complications of angle recession and glaucoma in patients after traumatic microhyphema appear similar to those found in patients after gross hyphema.

Purpose: Although musculoskeletal involvement is the common presentation, studies have reported the incidence of sports related ocular trauma. Here we present the case reports of two patients who sustained injury in one of the fast growing sports - the pickleball, during play without eye protection. Observations: Two patients with history of injury during pickleball play presented to our clinic with varying spectrum of ocular presentations. First patient had an anterior segment involvement with hyphema and elevated intraocular pressure, and the second patient had both anterior and posterior segment involvement causing angle recession and commotio retinae. Conclusion: Ocular injuries related to various sports have been extensively described, our intent is to increase the awareness about the possible ocular injuries related to rising pickleball and that improved safety measures and appropriate education to the players could prevent such ocular injuries.
RESUMO
Ocular trauma affects millions of people worldwide and is a leading cause of secondary glaucoma. Angle recession is the main cause of post-traumatic glaucoma after blunt eye trauma, and it is usually unilateral. The aim of this paper is to investigate the possible causes of angle recession with a bilateral presentation. Airbag activation during traffic accidents is a likely cause to be ruled out, along with repeated head or eye trauma, due to contact sports or a history of physical abuse. These aspects can aid in early detection, appropriate management, and improved outcomes for patients with ocular trauma. Finally, we report the case of a 75-year-old Caucasian man who developed a bilateral angle recession after an airbag impact, with advanced glaucoma in the right eye and ocular hypertension in the left eye. To our knowledge, this is the first case in the literature of chronic post-traumatic glaucoma probably caused by an airbag.
RESUMO
A teenage female patient visited the ophthalmology emergency department reporting blunt ocular trauma from a stretched elastic band, accompanied by blurred vision. At presentation, uncorrected visual acuity (VA) was 6/60 in the affected eye, improving to 6/7.5 with pinhole. A slit lamp examination showed a mild anterior chamber reaction and iridoplegia with pupil shape irregularity. Gonioscopy revealed partial cyclodialysis with angle recession. Fundoscopy revealed focal commotio retinae with blot hemorrhages. B-scan ultrasonography yielded no pathology. Follow-up examination, the day after the injury, included detailed refraction, which showed a myopic shift in the affected eye. Uncorrected VA improved to 6/15 and the patient achieved 6/7.5 with correction. Clinical findings indicated myopia, which resolved within one week from the incident, and refractive error rapidly decreased to prior emmetropic values.
RESUMO
PURPOSE: : To evaluate the outcomes of primary trabeculectomy with mitomycin-C (trab MMC) in phakic eyes with post-traumatic angle recession glaucoma with no prior intraocular surgeries. METHODS: : We included 32 phakic eyes of 32 patients who underwent trab MMC between January-2002 and December-2017. Complete success was IOP between 6 and 21 mm Hg without anti-glaucoma medications (AGM) and failure was when IOP >21 mm Hg with AGM or need for additional intervention for IOP control or loss of light perception. RESULTS: : Thirty-two eyes of 32 subjects with a mean age (± standard deviation) of 30.6 ± 12.6 years were included. The majority were male (97.6%) and the major cause of blunt trauma were sports injury in 28/32 eyes (88%) and 24/32 eyes (75%) had >180-degree angle recession. The Median (interquartile range) follow-up duration was 1.3 years (0.3,3.5). There was significant IOP reduction at 1-year postoperatively (34 (28,40) to 13 (12,16) mm Hg; p < .001). The median postoperative AGM at 1-year was significantly less (4 (3,4) to 0; p < .001) with stable Log MAR visual acuity (p = .24). The complete survival of trab MMC was 88% at 1 year and was 77% from 2 to 5 years. Complications were intraoperative vitreous prolapse needing limited vitrectomy in two eyes and postoperative choroidal detachment in two eyes that resolved with conservative management. The contralateral eyes of three patients (9.7%) developed elevated IOP during the follow-up period. CONCLUSION: : Trabeculectomy with mitomycin-C in phakic eyes with traumatic angle recession glaucoma showed good safety and efficacy in the medium-term follow-up. The contralateral fellow eye needs monitoring for glaucoma in these patients.

Background Badminton-related ocular injuries are among the commonest causes of blunt trauma to the eye, which can lead to significant damage to the ocular structures. This study aimed to assess the clinical presentations, complications, and visual outcomes of patients who sustained ocular injuries related to badminton treated in a single tertiary center in Malaysia. Materials and methods A retrospective clinical audit was conducted in Hospital Universiti Sains Malaysia (HUSM), Malaysia, involving patients diagnosed with ocular injuries related to badminton, either as players or spectators, between January 1, 2003 and December 31, 2017. The demographic data, mechanism of injury, and clinical presentation were recorded. In addition, visual acuity, anterior and posterior segment, and intraocular pressure (IOP) measurements were recorded at the initial presentation and at the present recruitment period. Management at the initial presentation was also obtained and recorded. The final visual outcome and complications were based on the finding of the most recent follow-up. Visual acuity was categorized as follows: mild or no visual impairment (6/18 or better), moderate and severe visual impairment (<6/18 and worse). Results A total of 23 patients (23 eyes) were included in this clinical audit. The average age was 24 years, with a range of 6-56 years, with the highest incidence occurring at the age of 20 years old and younger. The majority of the injuries were sustained during the single-player game. All the injuries were caused by shuttlecock hits. In 18 cases (78%), the trauma was caused by an opponent, in four cases (17%) by a partner, and in one case involving a bystander. Most of the patients in this series were not using any protective eyewear while playing the game 96% (22). Most injuries (22 eyes) involved the anterior segment, with hyphaema as the commonest clinical presentation. The mean IOP at presentation was 23.5 (11.2) mmHg. Angle recession was detected as early as one-week post initial presentation in 17 eyes. Commotio retinae (5 eyes) and vitreous hemorrhage (4 eyes) were the common posterior segment findings. There were eight eyes with visual acuity of worse than 6/18 at the initial presentation, but only three eyes had poor final visual acuity. There was a statistically significant improvement in visual acuity at the last follow-up compared to the initial presentation (Fisher's exact test) (p=0.032). Conclusion Ocular injuries related to badminton is common and cause a detrimental effect on the long-term visual outcome. Traumatic hyphaema and commotio retinae are the most common presenting signs related to poor visual outcomes. Therefore, protective eyewear and promoting awareness of badminton-related ocular injuries are essential to prevent monocular blindness in young adults.
RESUMO
SYNOPSIS: Angle recession, trabecular meshwork injury, increased trabecular pigmentation, and reduced Schlemm's canal dimensions can cause reduced aqueous outflow and unilateral glaucoma in an eye, following blunt trauma. Also, these patients are possibly at a risk to develop raised intraocular pressure (IOP) in the normal fellow eye due to reduced Schlemm's canal area. AIM: To identify and quantitatively evaluate Schlemm's canal (SC) parameters by anterior segment optical coherence tomography (AS-OCT) in the patients with unilateral 360° angle recession glaucoma (ARG) and compare with the fellow normal eyes and age-related normal control. MATERIALS AND METHODS: Six patients with a history of unilateral ocular blunt trauma and unilateral 360° ARG, normal fellow eyes and 34 age-matched normal controls underwent anterior chamber angle imaging with corneal line scan protocol using AS-OCT. Schlemm's canal cross-sectional area (SC-CSA) and meridional and coronal diameters were measured on temporal and nasal sections at 3 and 9 o'clock positions. RESULTS: In the AS-OCT cross-sectional images, SC was observed as a horizontally oval or ellipsoidal translucent space. The mean SC-CSA (1,710 ± 376.1 µm2 vs 6,100 ± 2,700 µm2, p < 0.0001), mean meridional diameter (243.6 ± 55.47 µm vs 474 ± 125.6 µm, p < 0.0001), and mean coronal diameter (32.68 ± 6.27 µm vs 57.42 ± 16.27 µm, p < 0.0001) of the SC were smaller in ARG eyes when compared with the normal eyes. The SC dimensions were reduced in the untraumatized fellow eyes of ARG patients when compared with the normal eyes (SC-SCA: 2350 ± 602.1 µm2, p = 0.001, meridional diameter: 341.8 ± 88.8 µm, p = 0.012 and coronal diameter: 31.67 ± 3.8 µm, p < 0.0001). There was no difference in the measured SC dimensions between the ARG eyes and the normal fellow eyes. CONCLUSION: The reduced SC parameters in the eyes with unilateral 360° ARG and the normal fellow eyes could mean that these patients probably have an underlying structural abnormality in the SC. Trabecular meshwork injury, angle recession, and increased trabecular pigmentation are probably the predisposing factors in the ARG eyes for the increase in IOP. Whether the normal fellow eyes develop IOP rise in the future needs to be seen during regular follow-up. HOW TO CITE THIS ARTICLE: Mansoori T, Reddy AA, Balakrishna N.

RESUMO
PURPOSE: To describe the results of selective laser trabeculoplasty (SLT) in eyes with angle recession glaucoma (ARG). To our knowledge, this is the first report of SLT being used as treatment modality for angle recession glaucoma. Argon laser trabeculoplasty (ALT) was used for ARG but showed a little therapeutic effect. OBSERVATIONS: Retrospective case series of 4 eyes of 4 patients with history of non-penetrating injury to the eye resulted in angle recession glaucoma. All eyes underwent SLT. Post-treatment, the best-corrected visual acuity (BCVA), intraocular pressure (IOP), number of glaucoma medications, additional need for intervention, and complications were recorded. Success of treatment was defined as an IOP reduction of 20% or reduction in medications and maintaining target IOP without further intervention during follow up period of more than 3 months.Mean patient age was 44 years (SD = 9) and 2 out of 4 were females. SLT treatment resulted in decreased IOP from 21 to 12 mmHg in one patient and from 26 to 20 mmHg with reduced medication burden in another patient and reduced medication burden in the third patient who stopped glaucoma medication with no significant change in IOP (from 10 to 14 mmHg) at last follow up visit at 45 months. Two SLT sessions failed in one patient who underwent tube surgery.In the 3 patients with successful treatment, IOP remained controlled for the duration of follow up ranging from 4 to 45 months. CONCLUSIONS AND IMPORTANCE: Predicting IOP outcomes after SLT is difficult in patients with ARG. Success was noted early in the post-treatment period and was maintained for years. Repeating SLT in a case of early failure didn't change the result and is not recommended. A larger study is required to confirm the safety and effectiveness of SLT for ARG.
RESUMO
Ocular trauma is a significant cause of blindness worldwide, particularly if associated with glaucoma. Direct damage from blunt or penetrating trauma, bleeding, inflammation, lens-related problems, orbital and brain vascular pathologies related to trauma, and chemical injuries may increase intraocular pressure and lead to traumatic glaucoma. Treatment may be as simple as eliminating the underlying cause in some conditions or management can be challenging, depending on the mechanism of damage. If proper management is not undertaken, visual outcomes can be poor. We discuss a broad spectrum of trauma-related mechanisms of intraocular pressure elevation, as well as their management.

Traumatic hyphemas present dilemmas to physicians. There are numerous controversies pertaining to the optimal approach to traumatic hyphema and no standardized guidelines for its management. We address some of these controversies and present a pragmatic approach. We discuss various medical agents and surgical techniques available for treatment, along with the indications for their use. We address the complications associated with hyphema and how to diagnose and manage them and consider the management of hyphema in special situations such as in children and sickle-cell anemia and in rare clinical syndromes such as recurrent hyphema after placement of anterior chamber intraocular lenses.

An 18-year-old male with 360 degree angle recession after blunt trauma in his right eye developed uncontrolled intraocular pressure (IOP) despite four antiglaucoma medications (AGM) with advancing disc damage. He underwent trabeculectomy with intraoperative mitomycin-c (MMC) application. There was an intraoperative vitreous prolapse which was managed accordingly. On post-surgery day 1, he had shallow choroidal detachment superiorly with non-recordable IOP. This was deteriorated 1 week postoperatively as choroidal detachment proceeded to serous retinal detachment. He was started with systemic steroid in addition to topical route. The serous effusions subsided within 2 weeks time. At the last follow up at 3 months, he was enjoying good visual acuity, deep anterior chamber, diffuse bleb, an IOP in low teens off any AGM and attached retina. This case highlights the rare occurrence of serous retinal detachment after surgical management of angle recession glaucoma.
RESUMO
·AIM: To study the influence of Ahmed glaucoma valve implantation on eyesight, intraocular pressure and corneal endothelial cell density of patients with traumatic angle recession glaucoma. ·METHODS: Totally 33 cases (35 eyes) of patients with traumatic angle recession glaucoma admitted to our hospital since June 2014 to June 2016 were selected and treated with Ahmed glaucoma valve implantation. The clinical data of all patients were retrospectively analyzed, so as to evaluated to success rate of surgery. Non-contact tonometer was applied to surveying intraocular pressure before treatment and at 1wk, 1,3,6mo and 1a post treatment. Specular microscope was adopted to examine and calculate the corneal endothelial cell density before treatment and at 1wk, 1, 3, 6mo and 1a post treatment. All affected eyes were compared for visual acuity before surgery and in 1a after surgery, moreover, patients were followed - up, received the further consultations and the complications were recorded. ·RESULTS: As for 35 affected eyes, the absolute success rate of surgery was 54% , while the relative success rate was 40% , and the total successful rate and failure rate were 94% and 6% respectively. In terms of the number of people who had no light sensation before surgery, or who had light sensation, ≤0. 01, 0. 01-0. 10 or >0. 10-0. 20, there was no significant difference (Z=-0. 132, P=0. 362). The intraocular pressure before treatment was 43. 43 ± 3. 65mmHg, at 1wk after surgery was 13. 50 ± 2. 54mmHg, at 1mo was 15. 93 ± 2. 61mmHg, at 6mo was 16. 00 ± 2. 18mmHg and at 1a was 16. 45 ± 2. 21mmHg, and the difference among different time points had statistical significance (F= 887. 82, P<0. 01). After treatment the intraocular press decreased compared to before treatment (P<0. 05); those after treatment had no difference with each other ( P> 0. 05 ). Before treatment, the corneal endothelial cell density was 2443. 35 ± 343. 12 pieces/mm2, in 1wk after the surgery was 2231.67±334.45 pieces /mm2, in 1mo after the surgery was 2065. 47 ± 336. 45 pieces /mm2, in 3mo after surgery was 2031. 47 ± 345. 76 pieces/mm2, in 6mo was 2001. 72±337. 18 pieces /mm2and in 1a after the surgery was 1979. 65 ± 301. 32 pieces /mm2, and the difference among different time points had statistical significance ( F = 13. 49, P<0. 01 ). After treatment the corneal endothelial cell density decreased compared to before treatment (P<0. 05); those after treatment had no difference with each other (P>0. 05). After surgery, there were 4 cases (4 eyes) of ocular hypotension, 3 cases (3 eyes) of hyphema, 2 cases ( 2 eyes) of drainage tube plugging and 2 cases ( 2 eyes ) of intraocular hypertension, which were all quickly relieved after basic intervention treatment. · CONCLUSION: Treating traumatic angle recession glaucoma with Ahmed glaucoma valve implantation can dramatically optimize the state of intraocular hypertension and protect the retaining visual acuity, and visual acuity can be optimized in some cases. It causes little complication that can be relieved with basic prognosis, but postoperative corneal endothelial cell loss exists in some cases.
