In the United Kingdom, it is estimated that 5,000 patients sustain eye injuries or ocular trauma requiring hospital admission annually, of which 250 patients will be permanently blinded. This study explores the cost-effectiveness of Adjunctive Steroid Combination in Ocular Trauma (ASCOT) given during surgery versus standard treatment in vitreoretinal surgery in patients with open globe trauma. This economic evaluation was embedded alongside the ASCOT RCT (ClinicalTrials.gov Identifier: NCT02873026). We conducted a primary cost-effectiveness analysis from a National Health Service perspective using the proportion of patients who achieved a visual acuity of 10 or more letter improvement on the Early Treatment Diabetic Retinopathy Study (ETDRS) scale as the measure of effect, in developing incremental cost-effectiveness ratios (ICERs). Secondary cost-utility analysis using the EuroQol 5 Dimension 5 Level (EQ-5D-5L) to generate a cost per quality-adjusted life-year (QALY), and a cost-effectiveness analysis using vision-specific quality of life (QoL) was conducted. Sensitivity analyses were also applied to investigate parameter uncertainties. The sample size of the ASCOT intervention arm and standard care arm of this study was 130 and 129, respectively. The intervention cost per patient was estimated at £132. The proportion of participants with an ETDRS of 10 or more letter improvement was 0.47 for the ASCOT group with a mean cost of £5,526 per patient, while the standard care group had an effect of 0.43 with a mean cost of £5,099 per patient. The ICER value of the primary outcome was £12,178 per 10 or more letter improvement on the ETDRS score. The secondary result in terms of cost per QALYs gained had a probability of 44% being cost-effective at a willingness-to-pay threshold of £30,000/QALY gained. Though there is no formally accepted cost-effectiveness willingness-to-pay threshold for 10-letter or more improvement, the ASCOT intervention for open globe trauma is a low-cost intervention. The ASCOT intervention is not cost-effective when compared to the standard care in this group and setting. The proportion of patients in the ASCOT intervention arm with 10 or more letter improvement produced some positive results but this is outweighed by the costs.

Purpose To compare the use of single‑pass four‑throw (SFT) and traditional double-pass two-throw knotting (DTT) techniques in pupilloplasty for traumatic mydriasis combined with lens dislocation, and to evaluate the learning curve between the two knotting techniques by wet lab. Method The eyes of 45 patients (45 eyes) were divided into two groups according to the knotting technique used: single‑pass four‑throw (22 eyes) or traditional double-pass-two-throw knotting (23 eyes). Combined phacoemulsification and pupilloplasty with pars plana vitrectomy were performed in traumatic mydriasis patients with lens dislocation. Preoperative and postoperative corrected distance visual acuity (CDVA), pupil diameter, intraocular pressure (IOP), pupilloplasty time, and complications were compared. Twenty ophthalmology residents were randomized to perform a pupilloplasty suturing exam with or without SFT knotting techniques in porcine eyes. Result All cases had a minimum follow‑up period of 6 months (range 6–12 months). There was no significant difference in the CDVA ( P  = 0.55), postoperative pupil diameter ( P  = 0.79), IOP ( P  > 0.05), anterior chamber exudate degree, and loosening or shedding of the line knot between the two groups. The duration of the pupilloplasty was 22.32 ± 4.58 min in the SFT group and 30.35 ± 5.55 min in the traditional group, which was a significant difference (P  < 0.01). The residents in the SFT group had higher test scores and fewer surgical mistakes ( P  < 0.05). Conclusion The SFT knotting technique has a similar treatment effect and safety as the traditional technique but requires a shorter time and is easier to perform in pupilloplasty surgery.

ObjectivesTo describe ocular injuries caused by badminton and to explore the implications for future prevention strategies.MethodsWe enrolled 85 patients with ocular trauma caused by badminton. Information collected from patients included type of game, instigator, instrument of injury and lessons in badminton from a professional, and ocular trauma information such as type of injury, treatment and final outcomes.ResultsThe 85 patients (52 men, 33 women) were aged 15–65 years with an average age of 42.9 (±10.7) years. In 60 cases the player was hit by a shuttlecock and in 25 the player was hit by a racquet. 73 cases occurred in doubles matches and 10 in singles matches. In 31 cases the trauma was caused by an opponent and in 52 cases by a partner; 2 cases involved bystanders, not players. About 70% (43/61) of the injured and 82% (40/49) of the instigators had not received badminton lessons from a professional. 80 injuries were non-penetrating and 5 were penetrating. There were 58 cases with hyphaema, 36 with secondary glaucoma, 23 with lens subluxation and 2 with retinal detachment. Surgery comprised phacoemulsification or lensectomy and vitrectomy in 16 cases, silicone oil tamponade in 2 cases, trabeculectomy in 3 cases and direct cyclopexy in 5 cases.ConclusionThe vast majority of the badminton related eye injuries occurred among doubles players and were instigated by the injured person’s partner. Non-penetrating injury was more frequent; penetrating injury was usually more serious. We recommend that badminton players use protective eyewear and receive safety education and professional coaching/instruction on techniques to protect against serious eye injuries.

Purpose: To examine the incidence, clinical findings and management of pellet gun-related ocular injuries that occurred during protests in Kashmir region. Methods: This retrospective study included records from 777 patients diagnosed with pellet gun-related ocular injuries admitted to a tertiary hospital in Srinagar, India, between July and November 2016. By reviewing the clinical records, the following data were collected: demographics, clinical information pertaining to the injury, imaging reports including computer tomography and ultrasonography B-scan, management in the emergency setting, and follow-up treatment. Results: Mean age was 22.3 ± 7.2 years and majority patients were male (97.7%). In terms of laterality, 94.3% and 5.7% of the patients sustained monocular and binocular injuries, respectively. In terms of the nature of injury, 76.3% of the eyes had open globe injury while 23.7% of the eyes had closed eye injury. Emergency surgical exploration was performed in 67.7% of closed globe injuries while emergency primary repair was done in 91.1% of open globe injuries. The vast majority of patients (98.7%) who required surgery underwent surgical intervention on the day of admission or the next day. Final best-corrected visual acuity (BCVA) after treatment was counting fingers or worse in 82.4% of the eyes. Conclusion: Pellet gun-related ocular injuries resulted in significant ocular morbidity, mostly manifesting as open globe injuries. Treatment often required surgical interventions, but despite expeditious management, visual prognosis remained poor for most of the patients.

We describe seven patients who were attempting to repair their garage door when a spring dislodged at high velocity, resulting in open globe injury. All patients were seen at Massachusetts Eye and Ear between the years 2008 and 2023. Their final visual acuities ranged from 20/125 to no light perception. Open globe injury appears to be a risk of attempts to repair a garage door by people who are inexperienced in doing so. [ Ophthalmic Surg Lasers Imaging Retina 2023;54:666–669.]

Objective To identify the epidemiological profile and prognostic factors of open globe injuries that require emergency surgical treatment. Design Retrospective cohort study. Subjects Patients with OGI who underwent publicly funded emergency surgical treatment in the Federal District from 2014 to 2018. Methods Data were collected by reviewing electronic medical records through a questionnaire and tabulated. The statistical analysis was performed in SPSS Statistics 26.0.0.0 ( p  ≤ 0.05). Results A total of 359 records were included, corresponding to 336 eyes of 334 patients (294 males and 40 females). The average age was 32.7 years. The affected eye was the right eye in 165 cases, the left eye in 166 cases, and both eyes in 3 cases. The average time between injury and hospitalization was 75.7 h, and the time between injury and surgery averaged 173.7 h. The injury types were as follows: 197 penetrating; 109 rupture; 19 IOFB; 11 perforating. The injuries were in the following zones: 181 zone I; 82 zone II; 70 zone III. The OTS grades were as follows: 57 were classified as grade 1; 101 were grade 2; 142 were grade 3; 28 were grade 4; and 8 were 5. The most commonly performed surgeries were corneal suture, corneoscleral suture, and evisceration. The most common clinical features were traumatic cataract, herniated iris and hyphema. The following were risk factors for poor prognosis: zone III, time between trauma and surgery > 72 h, rupture injury, retinal detachment, disorganization of the eyeball, endophthalmitis, uveal prolapse, OTS classification 1 or 2, and low initial visual acuity. The following factors predicted a good prognosis: initial VA > 1/200, penetrating injury, OTS 4 and zone II. Conclusions The high frequency of many of these factors may explain the high rate of severe visual loss found. Injury localization in zone II was identified as a previously unrecognized protective factor against severe visual loss.

AimsTo evaluate the efficacy and safety of intravitreal triamcinolone acetonide (TA) injection at the end of emergency surgery for open globe injury (OGI) to suppress traumatic proliferative vitreoretinopathy (TPVR).MethodsA single-centre, participant-masked, prospective, randomised controlled clinical trial. A total of 68 globe rupture patients with zone III were randomised to the control group (n=34) or the TA group (n=34) in 1:1 allocation ratio. Patients were treated with 0.1 mL TA in the TA group and 0.1 mL balanced salt solution in the control group at the end of emergency surgery. The primary outcome was the assessment of TPVR during vitrectomy 10±3 days later. Secondary outcomes included visual acuity (VA), retinal attachment rate, macular attachment rate, proliferative vitreoretinopathy (PVR) recurrent rate, side effects 6 months after vitrectomy.ResultsDuring vitrectomy, the TPVR grade of the control group was significantly more severe than the TA group (p=0.028). The TPVR score was significantly better in the TA group (9.30±0.82) than in the control group (6.44±1.06) (p=0.036). The final VA improved in 23 eyes (92%) in the TA group and in 14 eyes (63.64%) in the control group (p=0.008). The retinal attachment rates were 88% and 63.64% in the TA and control group, respectively (p=0.049). The two groups showed no significant difference in macular repositioning and PVR recurrent rate (p=0.215, 0.191). Temporary intraocular pressure elevation occurred in one eye in the TA group after emergency surgery.ConclusionsEarly intravitreal TA injection for OGI effectively reduces TPVR, increases surgical success and improves visual prognosis.

A man in his 60s presented with diminution of vision of the left eye with nasal bleeding after accidental fall. On examination his left upper eyelid was lacerated and left temporal sclera was punctured which was repaired under local anaesthesia after which he was discharged by ophthalmologists but continued to complain of pain and left nasal obstruction. A non-contrast CT of paranasal sinuses revealed fracture of medial wall of left orbit, left ethmoid haemosinus and a metallic foreign body (FB) in the septum and anterior face of sphenoid. Diagnostic nasal endoscopy performed to remove the metallic FB showed plastic splinters embedded in the mucosa of nasal cavity which was unexpected. Hence, the FB was removed in two sittings because of diagnostic dilemma.

Background Eyes sustaining open globe trauma are at high risk of severe visual impairment. Ocular injuries which result in visual loss invariably affect the posterior segment of the eye, and prevention of visual loss involves posterior segment (vitreoretinal) surgery. Despite improvements in vitreoretinal surgical techniques, outcomes in these patients remain unsatisfactory, and development of the intraocular scarring response proliferative vitreoretinopathy is the leading cause. Proliferative vitreoretinopathy is the most common cause of recurrent retinal detachment in these eyes; it is reported to occur in up to 45 % of cases. Methods/design The Adjunctive Steroid Combination in Ocular Trauma (ASCOT) trial is a multi-centre, double-masked, parallel-arm randomised controlled trial with an internal pilot designed to investigate the effectiveness and cost-effectiveness of using intravitreal and sub-Tenon’s triamcinolone acetonide peri-operatively in patients undergoing vitrectomy following open globe trauma. In total, 300 eyes of 300 patients will be recruited and randomly allocated to one of two treatment groups. Both groups will receive standard surgical treatment and routine pre-operative and post-operative treatment and care. The treatment group will receive an adjunctive peri-operative steroid combination (triamcinolone acetonide) consisting of 4 mg/0.1 ml into the vitreous cavity and 40 mg/1 ml into the sub-Tenon’s space. The trial incorporates a two-stage internal pilot to examine projected recruitment and retention rates. Progression criteria from the internal pilot study will enable us to determine whether to undertake the main trial. Patients and primary outcome assessors will be masked to treatment allocation. The primary outcome will be an improvement from baseline to 6 months of at least 10 on the corrected visual acuity as measured by ETDRS letter score. Secondary outcomes will be development of scarring, retinal detachment, intraocular pressure abnormalities, quality of life and public sector service use. Discussion This is the first powered, controlled clinical trial to investigate the use of adjunctive triamcinolone in patients undergoing vitrectomy following open globe trauma.
