Changing Trends in Firework-Related Eye Injuries in Southern China: A 5-Year Retrospective Study of 468 Cases

Firework-related eye injury is a horrible medical problem and creates huge health and social burdens. Herein, we explored the changing trends and demographic and clinical features of firework-related eye injury, in an effort to inform strategies to prevent this injury. We reviewed the data of 468 hospitalized patients who underwent surgery for firework-related eye injury at the Zhongshan Ophthalmic Center between January 2013 and December 2017. During this period, the trend in firework-related eye injuries was stable (mean, 93 ± 14 cases per year), and fireworks were the major cause of explosive eye injury. The average age of the patients was 24 ± 18 years and 87% of the patients were male, with boys under 10 years of age comprising the largest group (27% of patients). There were an average of 24 ± 7 cases per year from urban areas and 70 ± 8 cases from rural areas (). Furthermore, 21 ± 5% of cases occurred during Spring Festival. After treatment, the best corrected visual acuity was increased compared to that before treatment, and the intraocular pressure tended to become normal by the final visit (). The top three diagnoses were cataract (39%), retinal detachment (18%), and choroidal detachment (14%). Additionally, the most common surgery was cataract extraction (25%), followed by pars plana vitrectomy (19%) and pars plana vitrectomy plus pars plana lensectomy (10%). Over the five-year study period, day surgery hospitalization increased from 1% to 32%. This was associated with a corresponding decrease in the length of hospitalization, without adverse events, demonstrating that day surgery is feasible in firework-related eye injury cases. The present study results suggest that greater attention should be paid to firework-related eye injury, and a variety of measures should be taken to prevent this kind of ocular tragedy.

Effectiveness of Intravitreal Ranibizumab in Nonvitrectomized and Vitrectomized Eyes with Diabetic Macular Edema: A Two-Year Retrospective Analysis

The aim of this study was to compare the effectiveness of intravitreal ranibizumab (IVR) injections for the treatment of diabetic macular edema (DME) in eyes with and without previous vitrectomy. The medical records of 28 eyes (11 vitrectomized and 17 nonvitrectomized) of 28 patients (mean age, 59.0 ± 9.6 years; male to female ratio 1 : 1) who were diagnosed with DME and had received IVR treatment were reviewed retrospectively. The indications of vitrectomy in 11 vitrectomized eyes were intravitreal hemorrhage (n = 8) and epiretinal membrane (n = 3). The best-corrected visual acuity (BCVA), central macular thickness (CMT), and total macular volume (TMV) were measured at baseline and at months 6, 12, 18, and 24 of the follow-up. The number of IVR injections, the duration between diagnosis of DME and IVR injection, and the hemoglobin A1c (HbA1c) level at baseline were also recorded. Baseline demographics, HbA1c, BCVA, CMT, and TMV values were similar between two groups (). The duration between diagnosis of DME and IVR injections was similar in both groups (16 ± 5 months vs. 13 ± 4 months, respectively; ). IVR injection was performed 6.3 times in vitrectomized eyes and 6.1 times in nonvitrectomized eyes during the 24-month period (). The mean BCVA improved significantly during the 24-month period in both groups. The improvements in BCVA, in CMT, and in TMV were more significant at month 6 () group, at month 12 (), at month 12 (), and month 24 () in nonvitrectomized eyes, respectively, while there was no difference in improvements of BCVA, CMT, and TMV in vitrectomized group at each visit. Treatment effected by time in terms of BCVA, CMT, and TMV values in all groups (, , , respectively), not by time-group interaction and group (all values >0.05). In conclusion, IVR treatment for DME is equally effective in both groups. However, the response to treatment is seen earlier in nonvitrectomized eyes compared to vitrectomized eyes.

Management of Aphakia with Visual Axis Opacification after Congenital Cataract Surgery Based on UBM Image Features Analysis

Objective. The purpose of this study was to study the imaging features of ultrasound biomicroscopy (UBM) in the aphakia with visual axis opacification (VAO) after congenital cataract surgery. Methods. From May 2015 to May 2018, aphakia patients with VAO who underwent congenital cataract surgery were examined by high-resolution bag/balloon UBM technique, and the results of UBM imaging were analyzed. According to UBM imaging features, different types of VAO were classified. Results. A total of 38 children (55 eyes) with VAO were included. 17 patients were bilateral, and 21 patients were unilateral. Patients with VAO were classified into 3 groups according to the UBM imaging features: membranous fibrosis VOA (17 cases, 28 eyes), cortical regeneration VOA (15 cases, 20 eyes), and mixed VOA (6 cases, 7 eyes). The patients in the membranous fibrosis group underwent Nd:YAG laser posterior capsulotomy, those in the cortical regeneration group underwent anterior vitrectomy, and those in the mixed type group underwent anterior vitrectomy with RF capsulotomy tip. After surgery, VAO were removed in all patients. During the follow-up period, in the membranous fibrotic VAO group, iris adhesion and pupillary occlusion were found in 2 eyes, and anterior vitrectomy combined with separation of iris adhesion was performed. In cortical regenerative and mixed type VAO groups, anterior vitrectomy was performed without opacity in the axial region. The total recurrence rate of VAO was 3.46%. Conclusion. After congenital cataract surgery, the UBM imaging features of aphakia with VAO are helpful to evaluate the condition of VAO before reoperation so as to choose the optimal surgical method to achieve better therapeutic effect.

Automatic Quantification Software for Geographic Atrophy Associated with Age-Related Macular Degeneration: A Validation Study

Context. Geographic atrophy (GA) is usually measured manually using fundus autofluorescence (FAF) images, lacking a reliable, automatic method to do so. Aims. To determine the accuracy and repeatability of new software to automatically quantify GA areas associated to age-related macular degeneration (AMD) by swept-source optical coherence tomography (SS-OCT). Settings and Design. Tertiary referral hospital in Spain. Cross-sectional and noninterventional. Methods and Material. Forty-six eyes from 33 AMD patients with GA, without previous choroidal neovascularization, were scanned using a SS-OCT (Topcon Corporation, Japan), including three consecutive 7 × 7 mm OCT scans. Three independent masked observers manually measured the GA area using FAF images. These measures were compared to the three automatic determinations of the GA. Lesions were classified according to their morphology and number as regular/irregular and single/multiple. Statistical Analysis Used. Intraclass correlation coefficients (ICCs) were estimated to study the agreement between the three physicians in manual measurements. ICC through a two-way mixed effects model was used for the software measures, and Lin’s concordance correlation coefficient (CCC) was used to analyse the agreement between the physicians and the software. Results. The mean age was 76.3 ± 11.7 years. Eighteen cases showed regular lesions, and 30 showed single lesions. The CCC between manual and automatic measures was 0.95 for the whole sample. The CCC for the area according to the lesion type was 0.92 and 0.97; it was 0.99 for single lesions and 0.89 for multiple lesions. The ICC between the three physicians was 0.94 for the whole sample and 0.88 in multiple lesions. The ICC between the three automatic measures for the area was 0.98 for the whole sample, regular or irregular lesions, and single or multiple lesions. Conclusions. The accuracy of this new software is substantial for the area with a high degree of repeatability agreement, being very precise in single lesions.

Surgical Management for Refractory Bleb Dysesthesia

Purpose. To present long-term results of modified bleb-limiting conjunctivoplasty as a successful treatment for intractable bleb dysesthesia and to review the literature on the surgical management of dysesthetic bleb. Methods. Consecutive case series and literature review. We present four cases of surgically reduced painful blebs. Our technique consisted of the following steps: (1) conjunctival, radial incision to the bare sclera in the desired limit of the bleb; (2) suturing with buried, interrupted sutures at the nearest edge of the filtering bleb; (3) lower limbal peritomy including unwanted area of the extended bleb; (4) dissection and removal of the underlying fibrous tissue when present; (5) conjunctival and resorbable sutures. In addition, a systematic literature review was performed. Only reports presenting outcomes of surgical treatment of bleb dysesthesia after filtering procedure were included in review. Results. Four eyes were included consecutively in the study in a period of 4 years. On average, they developed circumferential bleb dysesthesia 9.3 ± 4.7 months after uneventful combined phacotrabeculectomy with Mitomycin C as primary procedure. Surgical reduction was decided after failure of lubricants in controlling ocular discomfort. Two cases showed a dense fibrous tissue beneath the conjunctiva that was excised to ensure filtration. In all cases, a rapid disappearance of symptoms with very good aesthetic and functional outcome was observed. After 12-month follow-up, patients remained asymptomatic and maintained intraocular pressure of 10.7 ± 1.2 mmHg without treatment. A systematic review of the literature obtained 15 eligible case series (n = 123) with rates of success within 46–100%, favoring less aggressive approaches to reduce bleb size. Conclusion. Bleb dysesthesia is a rare complication of filtering glaucoma surgery. This modified bleb-limiting conjunctivoplasty technique (with removal of subjacent fibrous tissue if present) is able to target the underlying etiology providing ocular discomfort relief while maintaining bleb function and may be considered as first-choice surgical treatment.

Portable Handheld Slit-Lamp Based on a Smartphone Camera for Cataract Screening

Purpose. As part of plans to provide help to people in remote and poor areas who have no medical resources, a portable slit-lamp based on a smartphone was proposed. This would help in early screening of cataract diseases. Methods. This means a microlens is designed that would work with a phone’s camera. The phone’s photo taking function is used in capturing the image of the eyes lens to replace the observation system of the desktop slit-lamp. A simplified slit light band was designed. In order for the light source part to meet the portable requirements of the slit-lamp, the adjustable and diffused light functions of the ligaments were removed in this design. Furthermore, the images collected by the smartphone are uploaded to the deep learning cataract screening system, which can achieve real-time and effective screening of cataract. Results. Unlike the desktop slit-lamp, which needs skilled personnel to operate, this device can be easily operated by less-skilled or inexperienced doctors. This eliminates the concerns of inaccurate diagnosis based on the use of unskilled professionals. Due to the portability, ease of use, and simplicity in obtaining crystal images of this device, it serves as a promising platform for nonhospital screening and telemedicine. Conclusions. In this paper, we invented a small portable device for screening cataract. This device is to make screening and diagnosis of cataract in remote areas very fast and effective. It will also solve the problem of inadequate specialized doctors and equipment in those areas as well. Translational Relevance. Smartphones can be used with portable slit-lamps to capture the images of the lens.
