Blunt Eye Trauma

A case of choroidal rupture caused by airbag-associated blunt eye trauma and complicated with massive subretinal hemorrhage and vitreous hemorrhage that was successfully treated with intravitreal injection of expansile gas and bevacizumab is presented. A 53-year-old man suffered from loss of vision in his right eye due to blunt eye trauma by a safety airbag after a traffic accident. On initial examination, the patient had no light perception in his right eye. Dilated ophthalmoscopy revealed massive subretinal hemorrhage with macular invasion and faint vitreous hemorrhage. We performed intravitreal injection of pure sulfur hexafluoride twice for displacement, after which visual acuity improved to 0.03. For persistent subretinal hemorrhage and suspicion of choroidal neovascularization (CNV), intravitreal bevacizumab (1.25 mg/0.05 mL) injection was administered. After 3 weeks, the visual acuity of his right eye recovered to 0.4. For early-stage choroidal rupture-induced subretinal hemorrhage and complications of suspected CNV, intravitreal injection of expandable gas and intraocular injection of antiangiogenesis drugs seem to be an effective treatment.

Ocular Injuries

INTRODUCTION: The study describes ocular injuries caused by airsoft guns pellets, type of these injuries and their incidence in different age groups. METHODS: This is a retrospective review of medical charts of patients who were hospitalized due to airsoft guns ocular injuries in ten-year period (from 2000 to 2009). Patient?s age, gender, duration of hospitalization, type of treatment and initial and final visual acuity were analyzed. RESULTS: Overall 92 patients with ocular injuries caused by airsoft gun pellets were hospitalized in tenyear period. In all patients only one eye was injured and there were 72 (78.3%) male patients. Injuries involved ocular adnexa, anterior and posterior segment of the eye. On initial examination 41 (44.6%) patients were presented with subconjunctival hemorrhages, 42 (45.6%) with corneal abrasion, 42 (45.6%) patients had corneal edema, 6 (6.5%) had traumatic mydriasis, 90 (97.8%) patients exhibited hyphema, 10 (10.9%) iridodialysis, in 27 (29.3%) patients high intraocular pressure (IOP) was measured, one patient had subluxation of intraocular lens (IOL) and one patient had traumatic cataract. Posterior segment findings included vitreous hemorrhage in 3 (3.3%) patients, retinal hemorrhage in 15 (16.3%) patients, retinal edema in 35 (38.0%) patients and one patient had globe rupture. Average duration of hospitalization was 5.7 days (range from 1 to 18 days). Three patients (3.3%) required eye surgery, eight patients (8.7%) had anterior chamber washout while rest of the patients were conservatively managed. Visual acuity at hospital release was significantly improved comparing to initial visual acuity, ranging from counting fingers at 1 meter to 20/60 in 7 (8.6%) patients, from 20/50 to 20/30 in 13 (16.0%) patients and from 20/25 to 20/20 in 61 (75.3%) patients. In 11 patients testing the visual acuity was not possible because of their young age. CONCLUSION: Injuries attributed to airsoft guns were confined mostly to anterior segment. There was also high percentage of severe posterior segment trauma requiring hospital admission. The most important factors in preventing such injuries are restricting access to airsoft guns, especially to minors, as well as mandatory use of protective equipment such as protective eyeglasses.

Background: To evaluate intravitreal injection of expansile sulfur hexafluoride (SF6) as a low cost and effective treatment for symptomatic vitreomacular adhesion (sVMA). Methods: Retrospective analysis of all patients with sVMA treated with pneumatic vitreolysis using SF6 gas presenting to a clinical practice from January 2005 and June 2013. Results: Six cases were included in the study. Five patients (83%) experienced complete resolution of the vitreomacular adhesion. One patient had a partial release of the vitreomacular adhesion. Four patients (67%) had a one line improvement in best corrected visual acuity. Conclusion: Due to its low cost, wide availability, and apparent efficacy, intravitreal injection of expansile SF6 should be investigated further as a possible treatment modality for sVMA.

ABSTRACT Introduction : In general, diabetic retinopathy is classified into early stage, namely non proliferative diabetic retinopathy (NPDR), and advanced stage, proliferative diabetic retinopathy (PDR). Diabetic macular edema is the most common cause of visual impairment in cases of early stage or NPDR. Purpose : To describe Diabetic Macular Edema (DME) with intravitreal injection of anti-VEGF as a treatment. Case report : 43 old female, came with chief complaint of blurred vision on her right eye since six months ago. Blurring is felt slowly. Patient has a history of uncontrolled diabetes since 10 years and a history of hypercholesterolemia since 1 year ago. visual acuity of the right eye is 4/60. On posterior segment examination, neovascularization of the papilla was found. Decreased foveal reflex (+), hard exudates (+) within 500 µm from the central macula. Microaneurism (+), dot hemorrhage (+), blot (+) in 4 quadrants, hard exudates (+) in 2 quadrants in her right eye. The patient was planned for intravitreal injection of anti-VEGF on her right eye. Conclusion : Intravitreal injection of anti-VEGF can improve visual acuity and reduce exudate and hemorrhage in retina from ophthalmoscope and fundus photography examination. In addition, the investigation with OCT was found to improve with reduced macular thickness.

Purpose. To present the case of a 27-year-old male patient with stage IV proliferative sickle cell retinopathy, treated with one intravitreal injection of ranibizumab, showing regression of the neovascularization and no recurrence at the 9-month follow-up. Methods. A 27-year-old male patient presented with blurred vision and floaters in the right eye since three days. His best corrected visual acuity was 6/18. Ophthalmological examination and fluorescein angiography revealed proliferative sickle cell retinopathy stage IV with vitreous hemorrhage and sea fan neovascularization, as well as ischemic areas at the temporal periphery. Results. The patient was treated with one intravitreal injection of ranibizumab, presenting improvement in the visual acuity from 6/18 to 6/6, resolution of vitreous hemorrhage, and regression of the neovascularization. Additionally, he underwent scatter laser photocoagulation at the ischemic areas. At the 9-month follow-up there was no recurrence, while no adverse effects were noticed. Conclusions. Intravitreal ranibizumab may be a useful adjunct to laser photocoagulation in the management of proliferative sickle cell retinopathy and may permit some patients to avoid pars plana vitrectomy for vitreous hemorrhage.

BACKGROUND: Spontaneous vitreous hemorrhage is uncommon in the general population. Of cases, 1020% are idiopathic or due to occult causes and a majority of the remainder are associated with diabetic disease. The evaluation and disposition of an aviator has not been reported previously. This case will document the work-up and safe return to flight of a patient.CASE REPORT: A 33-yr-old male MH-60R pilot presented with acute blurred vision in the left eye and eye pain which began at his desk. His review of systems was otherwise negative. His medical history was noncontributory. On initial examination his vital signs and external ocular exam were normal. He was immediately referred to the optometry clinic, where a dilated funduscopic examination (DFE) with scleral depression demonstrated a large floater OS composed of streaks of blood and tobacco dust. His DFE was otherwise normal with no retinal tears or vitreous detachments. On repeated DFEs, his intraoccular pressures remained normal and his hemorrhage resorbed without decreased visual acuity or field deficits. A hematologic work-up was negative. After 4 mo of observation, the patient was returned to flight status without further recurrence.DISCUSSION: No known associations exist between aeronautical duties and spontaneous vitreous hemorrhages. The stressors aviators are subjected to, such as high vibrations and increased g forces, may make them more likely to suffer intraocular microvascular damage that could lead to retinal detachment, vitreous detachment, and bleeding. Further reports are needed to determine the risks of recurrence in aviators and their differences from typical spontaneous vitreous hemorrhage patients.Wallace SA.

Abstract Backgrounds However there have been numerous investigations of intrascleral intraocular lens (IOL) fixation techniques, there is room for improvement in terms of simplifying complicated techniques and reducing the high levels of skill required. This study aimed to report a novel technique for sutureless intrascleral fixation of the IOL using retinal forceps with a 27-gauge trocar. Methods Nineteen eyes of 18 patients underwent intrascleral fixation of the IOL from July 2018 to September 2019 were enrolled in this study. A 27-gauge trocar formed 3-mm scleral tunnels positioned at 4 and 10 o’clock, 2 mm from the corneal limbus. We used a 3-piece IOL haptic grasped by a 27-gauge retinal forceps and pulled from the 27-gauge trocar. The IOL was fixed by making a flange. Main outcome measures were visual acuity, corneal endothelial cell density, IOL tilt, decentration, predicted error of refraction and complications. Results The 19 eyes were followed up for 1 month. The mean pre- and postoperative logMAR uncorrected visual acuity (UCVA) was 1.06 ± 0.63 and 0.40 ± 0.26, respectively (p < 0.01), while the mean pre- and postoperative logMAR best corrected visual acuity (BCVA) was 0.27 ± 0.51 and 0.06 ± 0.15, respectively (p = 0.09). The mean corneal endothelial cell density was 2406 ± 625 to 2004 ± 759 cells/mm2 at 1 month (p = 0.13). The mean IOL tilt was 3.52 ± 3.00°, and the mean IOL decentration was 0.39 ± 0.39 mm. There was no correlation among IOL tilt, decentration and BCVA (p > 0.05). The mean prediction error of the target refraction was − 0.03 ± 0.93 D. The complications were vitreous hemorrhage (3 eyes), hyphema (1 eye), IOP elevation (1 eye), iris capture of the IOL (1 eye) and hypotony (2 eyes). No IOL dislocation occurred. Conclusions IOL intrascleral fixation with a flange achieved good IOL fixation and visual outcome in the scleral tunnels created with the 27-gauge trocar.

Purpose: To describe surgical management and establish visual outcomes of open globe injury (OGI) in pediatric patients requiring vitrectomy. Methods: Forty-eight eyes of 48 pediatric patients underwent vitrectomy for OGI with secondary vitreoretinal complications in the eye center of Jilin University were included. Characteristics of patients, details of ocular examination and operation, presenting and final visual acuity were recorded. Results: Presenting visual acuity less than 20/400 was found in 44 eyes (91.7%), which included no light perception (NLP) in four eyes. At last visit, there was no eyes with visual acuity of NLP, and 19 eyes (39.6%) had a vision recovery to 20/400 or better. Mechanisms of injury, intraocular contents prolapse, presence of hyphema, intraocular foreign body, vitreous hemorrhage, retinal detachment, and total time from injury to PPV > 2 weeks were significant predictors of visual prognosis. Logistic regression analysis showed that hyphema was a significant predictive factor for poor visual outcome. Conclusion: Visual acuity was improved in most of the patients with OGI in this study. Hyphema is an important presenting ocular sign in estimating the post-vitrectomy visual outcome for OGI in children. Proper timing of vitrectomy is suggested, and in this study patients may benefit more with early vitrectomy as less proliferative vitreoretinopathy (PVR) was found together with a better visual acuity.

Purpose: To investigate the natural history of idiopathic epiretinal membrane (ERM) in eyes with good visual function using optical coherence tomography (OCT). Methods: Sixty-two eyes of 58 patients with idiopathic ERM, visual acuity of 20/40 or better, and no significant metamorphopsia were included. The best corrected visual acuity (BCVA), central macular thickness (CMT), membrane configuration, and ellipsoid zone signal data over 24 months were retrospectively analyzed. Based on OCT findings, ERM configurations were categorized as global attachment (GA), partial attachment (PA), pseudohole, and vitreomacular traction (VMT). Results: The mean BCVA and CMT did not change significantly between baseline and 24 months. GA, PA, pseudohole, and VMT types were observed in 33, 19, 9, and 1 eye at baseline, and in 20, 22, 10, and 1 eye at 24 months, respectively. A membrane configuration change was noted in 24 eyes (38.7%) during follow-up, and the distribution shifted from GA to the other types (p < 0.001). Six eyes had visual loss due to membrane progression, and 4 eyes had spontaneous membrane separation. Of the 10 eyes with progression or separation, 6 were of the PA type. Conclusions: Although the BCVA remains stable over 2 years in most idiopathic ERM eyes with good visual function at baseline, the membrane configuration may change, affecting visual acuity. The GA type would be an early stage, and the PA type is prone to changes in visual acuity.

Blunt Ocular Trauma

Open globe injury (OGI) is a severe form of eye trauma. It is an important cause of monocular blindness worldwide. Ruptures from blunt trauma are most common at the sites where the sclera is thinnest, at the insertions of the extraocular muscles, and at the limbus. Most often, rupture is equatorial. We present a unique case of open globe injury due to blunt ocular trauma from a thrown rock that resulted in a meridional rupture of the eye. The pertinent literature is reviewed.
