Ocular Injuries

A postal survey was conducted to determine the use of eye protection and incidence of ocular trauma in orthodontic practice. One-hundred-and-fifty-nine NHS orthodontic consultants and 203 specialist orthodontic practitioners were surveyed. Two-hundred-and-forty-one(66·5 per cent) replies were received. Some form of eye protection was routinely worn by 66·8 per cent of orthodontists, 64·3 per cent of patients, but only 33·6 per cent of DSAs. Eye protection was not offered to DSAs in 31·9 per cent of practices or to patients in 22·1 per cent. Forty-three per cent of orthodontists reported instances of ocular injury in their practices. The majority of these injuries (n = 104) occurred during debonding or trimming acrylic. Other incidents involved ligating materials, intra-oral polishing, and acid etching. Most injuries (83·5 per cent) were treated in the surgery without any long-term effects. The routine use of goggles or spectacles with side-pieces and plastic lenses, which conform to British Standard BS 2092, is recommended for staff and patients during all operative procedures in orthodontic practice.

Purpose. To assess the clinical and morphological outcomes of topography-guided accelerated corneal cross-linking. Design. Retrospective case series. Methods. 21 eyes of 20 patients with progressive keratoconus were enrolled. All patients underwent accelerated cross-linking using an ultraviolet-A (UVA) exposure with an energy release varying from 7.2 J/cm2 up to 15 J/cm2, according to the topographic corneal curvature. Uncorrected (UDVA) and corrected (CDVA) distance visual acuity, topography, in vivo confocal microscopy (IVCM), and anterior segment optic coherence tomography (AS-OCT) were evaluated preoperatively and at the 1, 3, 6, and 12 months postoperatively. Results. 12 months after surgery UDVA and CDVA did not significantly vary from preoperative values. The average topographic astigmatism decreased from -4.61±0.74 diopters (D) to -3.20±0.81 D and coma aberration improved from 0.95 ± 0.03 μm to 0.88 ± 0.04 μm after surgery. AS-OCT and IVCM documented differential effects on the treated areas using different energies doses. The depths of demarcation line and keratocyte apoptosis were assessed. Conclusions. Preliminary results show correspondence between the energy dose applied and the microstructural stromal changes induced by the cross-linking at various depths in different areas of treated cornea. One year after surgery a significant reduction in the topographic astigmatism and comatic aberration was detected. None of the patients developed significant complications.

Background: Surgical success rate of strabismus is variable. Objective: To evaluate the outcome of monocular strabismus surgery for adults with largeangle deviation. Subjects and methods: This study was that of a retrospective interventional case series. A total of 48 consecutive adult patients with large-angle socially-noticeable strabismus underwent clinical evaluation for squint surgery. They were divided into 2 groups of which 28 had exotropia while 20 had esotropia with deviation ranging from 40 to 80 prism diopters (PD). Visual acuity measurement (V/A), cycloplegic refraction and orthoptic evaluation were done in all cases along with detailed anterior segment evaluation. Fundus examination was carried out with indirect ophthalmoscope and slit-lamp bio-microscopy with + 90 D lens. For each case, a repeat evaluation was done after a six-week interval. The surgical procedure was monocular recession and resection carried out under peri-bulbar anesthesia by the same surgeon. Post-operative visual acuity, fusion, stereopsis and ocular alignment were noted in all cases during follow up visits. Results: Successful ocular alignment (< 10 PD) was achieved in 40 patients while binocularity was noted in 3. Forty patients were happy with the cosmetic outcome and psychosocial rehabilitation. No statistically significant improvement was noted in visual acuity and binocular function. Successful alignment was related to pre-operative deviation of less than 30 degrees. Conclusion: Monocular surgery under peri-bulbar anesthesia is a useful procedure for large-angle horizontal strabismus.

Purpose To determine the nature and types of domestic eye injuries. Methods The authors prospectively analyzed data of 100 consecutive patients with domestic eye injury (104 eyes) referred to the emergency room of Farabi Hospital during October 2003. Standardized international classification of ocular trauma (Birmingham Eye Trauma Terminology) was used for eye injury classification. Results Domestic ocular trauma represented 4.85% of all ocular emergencies (2061 patients) referred to the emergency room during that period. Male to female ratio was 1.13 and mean age of patients was 26±18 years (range, 1–73). Cornea was involved in 50.0% and sclera, lens, and retina each was involved in 4.8%. There was severe visual loss (best-corrected distance visual acuity <20/200 due to trauma) in 4% of the patients. The most frequent domestic ocular injury was globe injury (93.7%) including mechanical (72.1% closed and 4.8% open), chemical (14.4%), and thermal (1.9%) injuries. Conclusions Closed mechanical injuries were the most common type of domestic ocular injury in our series. Considering the high rate of domestic eye trauma among ocular emergency cases, more preventive measures should be taken at home.

Penetrating Ocular Trauma

Endophthalmitis refers to inflammation of both the anterior and posterior intraocular chambers and their structures. This vision-threatening condition occurs in three principal scenarios: penetrating ocular trauma, after intraocular surgery, and in systemically infected (often immunocompromised) patients. Endophthalmitis presents with marked intraocular inflammation, often with hypopyon. Patients report pain and significant vision loss out of proportion to typical post-operative complaints. It is distinguished from uveitis by both history and slit lamp examination. Endophthalmitis is an ophthalmic emergency. Same day ophthalmology consult/referral is mandatory. Vision is threatened over the course of hours. Treatment includes prompt intravitreal injection of antibiotics by an ophthalmologist. Systemic therapy should occur only in in endogenous infections, continuing until cultures clear.

Abstract Introduction Empty bullet-related ocular injuries (EBOI) are rare and may result in unfavorable visual outcomes due to both open globe and closed globe injuries. To our knowledge, no reports of such injuries in terms of outcomes have been previously described in the literature. The aim of this study was to describe the treatment performed and ocular outcomes of such injuries. Materials and Methods EBOI of 23 cases were reviewed who were referred to Gulhane School of Medicine Department of Ophthalmology between January 1998 and January 2018. Patient demographics, ocular signs (initial and final), injury types, type and number of interventions, and ocular trauma scores were recorded. Results In total, 23 eyes of the 23 patients with an average age of 22.3 ± 4.54 years (range, 20–41 years) were included in the study. All of the patients were male, and all injuries were due to empty bullets during shooting training. None had ocular protection at the time of ocular injury. Fourteen patients (60.9%) were open globe injuries, whereas nine (39.1%) of them were closed globe injuries. Mean ocular trauma scores category of the cases was 2.52 ± 1.03. The baseline and final visual acuity was 20/200 or better in 21.7% and 69.5% of eyes, respectively. Nineteen eyes (82.7%) had undergone a total of 31 surgeries with a 1.34 ± 0.88 surgery average. Conclusions The prognosis of EBOI is unpredictable and is dependent on the severity of ocular damage. The best treatment option is prevention of EBOI with protective eyewear.

Ocular Injuries

BACKGROUND Ocular injuries due to road traffic accidents (RTA) is one of the important causes of ophthalmological morbidity and cause of unilateral blindness. Some of the injuries also result in cosmetic disfigurement. Increased usage of vehicles for transport in recent times has increased the incidence of cases. The primary objective of this study was to understand the epidemiology and pattern of ocular trauma in RTA cases and their visual outcome. METHODS A total of 75 cases was included in the study following the inclusion and exclusion criteria. A detailed history was taken which included information regarding time, location, type and mechanism of injury, use of spectacles, car safety belts, and helmets. The time interval between injury and reporting was recorded. Test of visual acuity was done, ophthalmic examination included the examination of all patients with the slit lamp, 90 D examination, and indirect ophthalmoscopy were done. Ultrasound B scan was done in cases where unclear media prevented fundus examination. RESULTS Ecchymosis of the lids was the commonest type of ocular injury. Out of 15 eyelid laceration cases, 10 cases were with mild partial-thickness tears present and 5 had severe lid tears which required suturing. Most of the patients recovered with good vision in 6 months post-treatment and a few fair results. Analysis of variance (ANOVA) comparison between conservative management and surgical management at the end of 4 months post treatment was done. The P-values were > 0.05 hence, not significant. It indicated that the outcomes were independent of the method of management adopted. CONCLUSIONS The incidence of RTAs is increasing due to an increase in the number of vehicles used by the public. Ocular injuries are more often seen in young men especially those driving two-wheelers without safety devices like helmets. Open globe injuries and cases with previous ocular problems have poor outcomes. KEYWORDS Ocular Trauma, Road Traffic Accidents [RTA], Visual Outcome

A 6-year-old systemically healthy child presented with visual acuity of 1/60, N18 oculusdextrus (OD), and 6/18, N6 oculus sinister (OS). Slit-lamp biomicroscopy revealed suspicious bilateral inferotemporal pigmented ciliary body (CB) tumour, protruding posterior capsule and temporal posterior subcapsular cataract oculus uterque. Anterior segment optical coherence tomography, ultrasonography, ultrasonic biomicroscopy and Scheimpflug imaging revealed protruding posterior capsule and cortex abutting but not arising from CB suggestive of peripheral pigmented posterior lenticonus with hypermetropia (axial length 20.27 mm OD and 19.97 mm OS). Aberrometry revealed high internal aberrations and low Dysfunctional Lens Index (DLI). Lens aspiration with intraocular lens implantation in the bag OD and contact lens correction OS were undertaken. The child had a postoperative visual gain of 3/60, N18 with improved aberrometric profile OD, and was advised amblyopia therapy. Rarely posterior lenticonus can mimic a CB mass. Multi-modal ocular imaging can aid in its diagnosis and management. DLI may serve as a useful indicator of surgery in such cases.

A Prospective Study

BACKGROUND Occupational ocular injuries are very common in industrial and agricultural workers. These are important and preventable causes of ocular morbidity. Objective of the study was to profile occupational ocular trauma clinicoepidemiologically. METHODS A prospective study was done by collecting data from a standardised questionnaire and complete ophthalmological examination of patients with occupational eye trauma attending VSSIMSAR, Burla, between January 2019 and October 2020. RESULTS Out of 128 cases of work related injuries, males were 85 %. 48 % of the cases were between 21 - 40 years. Out of all cases 66 % injuries were related to industrial work followed by 29 % in agricultural sector and farming. 3 % of cases were due to blast injury. Also there were 3 % cases of chemical conjunctivitis. Most injuries were closed globe (85 %), mostly involving zone 1 (91 %). Open globe injuries were 15 %, majority of them involved zone 2 (47 %). Ocular superficial foreign bodies were the most common clinical entity (60 %), majority of them being metallic in nature (37.5 %). In 4 % cases IOFBs were found. Cornea was the most common ocular structure to get injured (69 %). Out of all cases, 50 % had ocular trauma score (OTS) of 4, and 4 % cases had OTS 2. 48 % of patients presented within 6 hours of injury. 42 % patients were not aware of any eye protective gear at work and 30 % patients were aware but did not use any eye protection. CONCLUSIONS Eye trauma in workplace is an important public health concern in economically productive population. Significant proportion of these injuries is avoidable by using standardised eye protective devices. Attention need to be given for instruction, enforcement of protective eye wear use, and frequent prevention campaigns.
