COVID-19 pandemic impact on ocular trauma in a tertiary hospital

AIM: To analyze the impact of the coronavirus disease- 2019 (COVID-19) pandemic on the presentation and characteristics of patients hospitalized for ocular trauma in a tertiary hospital in China between 2019 and 2020.METHODS: A retrospective case study was designed to collect information on all cases of ocular trauma in a tertiary hospital from 2019 to 2020 and compare differences in inpatients’ data (age, sex, admission vision acuity, type of diagnosis, hospital stays, mechanism of injury and location of injury).RESULTS: The total number of patients admitted to the Ophthalmology Department was 883 (mean 73.58±11.25 patients per month) in 2019 and 714 (59.50±17.92 patients per month) in 2020. The injury number of in work was also the most within the four types of location in this two year (42.36% in 2019, 43.84% in 2020). The mean hospital stays were 12.66d in 2019 and 10.81d in 2020. The highest incidence of ocular trauma was the middle-aged (41-65y) groups in 2019 and 2020. The most common cause of ocular trauma was sharp object in 2019 (47.34%) and 2020 (47.58%). The mechanical ocular trauma reaches 98.98% in 2019 and 99.72% in 2020.CONCLUSION: The number of patients with ocular trauma decreased in 2020, but middle-aged (41-65y) are still high incident groups. Mechanical ocular trauma remains the leading cause of hospitalization for ocular trauma patients and the proportion of patients injured at home increases. It is necessary to arouse social attention and the public’s awareness of eye trauma protection should be strengthened during the pandemic.

Resident-performed immediate sequential bilateral cataract surgery during the COVID-19 pandemic

Purpose:To assess visual outcomes and patient satisfaction for senior resident-performed immediate sequential bilateral cataract surgery (ISBCS) versus delayed sequential bilateral cataract surgery (DSBCS) during the COVID-19 pandemic, when minimizing healthcare-related exposures for patients and providers are paramount.Methods:This was a pilot retrospective cohort study of all ISBCS and DSBCS patients who underwent senior resident-performed cataract surgery from May to September 2020 at a single academic institution. Outcome measures were final corrected distance visual acuity (CDVA), final manifest refraction (MRx), intraoperative and postoperative complications rates, total number of visits, and patient satisfaction assessed postoperatively by telephone questionnaire.Results:Twenty-two eyes of 14 patients and 56 eyes of 28 patients underwent senior resident-performed ISBCS and DSBCS, respectively. Final CDVA was 20/25 or better in 21 (95%) ISBCS and 51 (91%) DSBCS eyes (P = 0.670). Deviation of final MRx from target refraction was within 0.50 D in 17 (77%) ISBCS and 47 (84%) DSBCS eyes (P = 0.522). There was no significant difference in intraoperative (P = 1.000) or postoperative (P = 1.000) complications. ISBCS patients averaged 3.5 fewer visits than DSBCS patients (5.9 vs 9.5, P < 0.001). All ISBCS and 20 DSBCS patients (87%) reported they were “very satisfied” or “satisfied” with their experience (P = 0.701). Five of six senior residents responded that they preferred performing ISBCS over DSBCS.Conclusion:This early experience suggests that senior resident-performed ISBCS is as safe and effective as DSBCS, with the added benefit of averaging fewer in-person visits. Residency programs should consider offering senior resident-performed ISBCS to select patients during the COVID-19 pandemic.     

Impact of COVID-19 pandemic and national lockdown on ocular trauma at a tertiary eye care institute

Purpose:To evaluate the impact of the COVID-19 pandemic and the national lockdown on the demographic and clinical profile of patients presenting with ocular trauma.Methods:In this retrospective, hospital-based, comparative analysis, patients presenting to the emergency department with ocular trauma in the following COVID-19 period (March 25, 2020 to July 31, 2020) were compared with patients in the pre-COVID-19 period (March 25, 2019 to July 31, 2019).Results:Overall, 242 patients (COVID-19 period: 71 and pre-COVID-19 period: 171) presented with ocular trauma. The mean age of the patients in COVID-19 and pre-COVID-19 periods were 26.7 ± 17.3 and 34.1 ± 20.3 years, respectively (P = 0.008). A majority of patients (68.6%) in both groups were from the rural background. Home-related injuries were common in the COVID-19 period (78.8%) as compared to pre-COVID-19 period (36.4%) (P < 0.0001). Iron particles (29.5%) were the common inflicting agents in the COVID-19 period while it was plant leaves (25.5%) in the pre-COVID-19 period. The most common ocular diagnosis was open globe injury (40.8%) in the COVID-19 period and microbial keratitis (47.9%) in the pre-COVID-19 period. Surgical intervention was required in 46.4% of patients in the COVID-19 period and 32.1% of patients in the pre-COVID-19 period (P = 0.034).Conclusion:During the COVID-19 period, there was a significant decline in the number of patients presenting with ocular trauma. In this period, a majority of patients sustained ocular trauma in home-settings. About half the patients required surgical intervention which was most commonly rendered in the form of primary wound repair.     

Ophthalmology practice during COVID-19 pandemic: A survey of Indian ophthalmologists

Purpose:To assess the ophthalmic practice pattern among ophthalmologists in India amidst the COVID-19 pandemic.Methods:An online questionnaire-based analysis was performed among members of the All India Ophthalmological Society (AIOS) and results were analyzed using SPSS software version 20.Results:A total of 2253 responses were received. The majority of the participants (72.6%) were between 30 and 60 years of age and were into private practice (64.7%). During the lockdown, over one-third of participant ophthalmologists reported not attending any OPD patients, whereas a majority (64%) provided only emergency ophthalmic services. During the COVID-19 pandemic, <15% surgeries were performed compared to the pre-COVID-19 era by 81% of participants, whereas elective surgeries were performed by only 4.3%. The proportion of participants utilizing telemedicine in ophthalmology showed a two-fold rise from the pre-COVID-19 era (21.9%) to the COVID-19 pandemic (46%). Over half of the participants reported following the AIOS guidelines, reducing clinic hours, use of screening questionnaires, minimizing staff, and use of breath shield on a slit lamp as precautionary measures to reduce the exposure. Over 95% of ophthalmologists were satisfied (score > 5/10) by the AIOS guidelines for ophthalmic practice during COVID-19.Conclusion:COVID-19 pandemic has adversely affected the ophthalmic care services across India with telemedicine emerging as a major rescue. The majority of practicing ophthalmologists are satisfied with guidelines provided by AIOS for ophthalmic care during the COVID-19 pandemic and have implemented the same in their setup.     

Changing patterns of posterior segment trauma during the COVID-19 pandemic: A regional analysis from the Bodhya Eye Consortium

Purpose:To assess changes in the presentation patterns of posterior segment trauma during the COVID-19 pandemic from six tertiary eye care institutes of North and Central India.Methods:A multicenter, hospital-based, retrospective comparative analysis of patients presenting with posterior segment trauma was done during the COVID-19 (Group A) (March 25, 2020 - September 30, 2020) period and the pre-COVID-19 (Group B) (March 25, 2019 - September 30, 2019) period.Results:A total of 405 patients were diagnosed with posterior segment trauma (Group A: 206, Group B: 199). The time interval between onset of trauma and presentation was higher in Group A (16.59 ± 29.87 days) as compared to Group B (9.41 ± 19.19 days) (P = 0.004). A majority of patients in Group A had a history of prior consultation before presentation (P = 0.049). In Group A, 120 (58.2%) patients sustained ocular trauma at home as compared to 80 (40.2%) patients in Group B (P < 0.0001). Patients presenting with light perception were significantly more in Group A (43.7%) as compared to Group B (30.2%) (P = 0.004). In Group B, 37.6% patients had presenting visual acuity of counting finger or better as compared to 27.6% patients in Group A (P = 0.07). Patients in Group A had a significantly higher proportion of post-traumatic endophthalmitis with delayed presentation (P = 0.011) and retinal detachment (P = 0.041). Patients undergoing surgery for foreign-body removal were significantly fewer in Group A (P = 0.05).Conclusion:Although the number of patients presenting with posterior segment trauma was comparable in Groups A and B, a greater number of patients sustained home injuries during the COVID-19 pandemic. A majority of these patients had delayed presentation with poor presenting visual acuity and a higher tendency of retinal detachment.     

Reasons for delay in cataract surgery in patients with advanced cataracts during the COVID-19 pandemic

Purpose:To analyze the reasons for delay in cataract surgery in patients with advanced cataracts during the COVID-19 pandemic.Methods:This was a prospective, cross-sectional, multicenter questionnaire study which included patients with mature cataract, nuclear sclerotic cataract grade IV, and cataracts with best corrected visual acuity (BCVA) <5/60, during the COVID-19 pandemic from December 2020 to April 2021. Reasons for delay in presentation to the hospital were analyzed.Results:One thousand four hundred seventy two patients were recruited with advanced cataracts. Absence of ophthalmic care nearby (44.2%), lack of awareness regarding elective surgeries (42.6%), lack of public transportation (37%), fear of contracting COVID-19 (23.4%), and waiting for outreach camps (20.4%) were found to be the reasons behind the delay in cataract surgery. 53.7% of the patients had worsening of defective vision and 55.3% of them had difficulty in carrying out activities of family living. 30.8% of the patients faced difficulty in commuting and 8.4% of the patients suffered a fall during this pandemic due to worsening of the visual acuity.Conclusion:The lockdown imposed during the pandemic has created a significant backlog of patients who are progressing to advanced cataracts due to lack of ophthalmic care nearby, lack of awareness regarding elective surgeries, lack of public transportation, and no outreach camps. Proactive measures to deal with this backlog are of utmost need to prevent blindness due to cataract.     

Macular infarction and traumatic optic neuropathy following blunt ocular trauma

Macular infarction is a visually disabling condition caused by a variety of reasons. It has rarely been described in association with blunt ocular trauma. We describe the case of a young healthy male who sustained injury with a bull’s leg and presented with severe visual loss owing to macular infarction and traumatic optic neuropathy. This report of an angiographically documented macular infarct secondary to ocular contusion highlights an additional feature in the spectrum of ocular findings following blunt trauma that might lead to a severe and permanent affliction of vision.     

A survey of ocular trauma

A four-year survey of all ocular trauma cases admitted to a large metropolitan eye hospital was conducted for the purpose of generally documenting ocular trauma and evaluating prophylactic, demographic and etiologic factors. Of 6254 eye admissions, 7.5% were for ocular trauma; hyphema was the most common diagnosis. Injuries were evaluated according to site, cause, and age, sex and race distribution.     

Iridodialysis repair – A simplified approach

Background:Iris root is the thinnest and weakest portion of the iris stroma. It can detach easily due to blunt trauma or accidental engagement of the iris during intraocular surgery resulting in glare, photophobia and monocular diplopia. Multiple techniques described for iridodialysis repair such as hang back technique, stroke and dock technique and sewing machine technique are technically challenging.Purpose:To describe an simplified approach of iridodialysis repair using 9-0 prolene suture.Synopsis:We demonstrate the technique of iridodialysis repair using animation for better understanding. Scleral flap is made adjacent to the iridodialysis area and a paracentesis is made oppsite to the iridodialysis. One arm of the double armed straight needle with 9-0 prolene suture is passed through the paracentesis into the iris root and docked in the 26G needle which is passed underneath the scleral flap 1.5mm posterior to the limbus. Then the needle is pulled out underneath the scleral flap and the manoeuvre is repeated for the second arm as well. The sutures are secured with 5-6 knots under the scleral flap. Intra-operative surgical videos of two patients with traumatic cataract and iridodialysis following blunt trauma are shown. After stabilizing the detached iris using iris hooks, phacoemlsification is done with implantation of foldable acrylic IOL, followed by iridodialysis repair as described above. Both the patients were relieved of their pre-operative symtoms and had good visual recovery.Highlights:We describe a simplified approach of iridodialysis repair that can significantly reduce the patient’s troublesome symptoms such as glare and monocular double vision.Online Video Link: https://youtu.be/-axYnSfWSb0     

Essentials of setting up a wet lab for ophthalmic surgical training in COVID-19 pandemic

Wet labs are an extremely important training tool, especially in times of a global COVID-19 pandemic, where surgical training can be minimal. They help the trainee learn and practice in a risk-free environment, without an imminent of a complication or failure, also allowing them the chance to execute the steps of a surgery repeatedly. We summarize all the key ingredients required from setting up a wet lab to improve the surgical skill of the trainees. The review also discusses various eyeball fixating devices, preparation of the eye for various types of ocular surgeries, and the role of simulation-based training in today''s scenario.     

Iris cerclage pupilloplasty and IOL implantation for traumatic mydriasis and aphakia after the blunt trauma of the eye

Four patients with traumatic mydriasis and aphakia following blunt injury of the eye globe were evaluated. Patients with severe glare and photophobia due to wide pupil diameter from 6.0 to 9.0 mm were managed by combined iris cerclage pupilloplasty and retropupillar iris-claw lens implantation. The postoperative anatomic results, visual acuity, subjective degree of glare, photophobia, as well as intraoperative and postoperative complications were evaluated. The mean follow-up time was 32.6 months. Best-corrected visual acuity improved in all patients from preoperative 20/60, 20/30, 20/25, 20/22 to postoperative 20/20, 20/22, 20/20, and 20/20 (Snellen charts). All eyes achieved satisfactory anatomic result with round pupil diameter 3.5–4.5 mm. Glare and photophobia disappeared in all patients. There were no intraoperative or postoperative complications. During the follow-up period, pupils remained round and iris-claw lenses well positioned, without tilting. Combined iris cerclage pupilloplasty with retropupillar iris claw lens implantation appears to be a safe and effective surgical technique in reducing pupil size and improving visual outcomes. It is also a cost- and time-effective procedure, providing great results with a single surgery.

Ophthalmic practice during COVID-19 pandemic

AIM: To compare the visual acuity (VA), comfort, and patient preference in a soft toric contact lens (TCL) versus soft spherical contact lens (SCL) in low astigmatic subjects during the contact lens (CL) trial. METHODS: This subject-masked, block randomized, 2×2 crossover study recruited 40 neophyte subjects (80 eyes) aged 18 to 33y with astigmatism in the range of 0.75-1.25 D with or without spherical power from -6.00 D to +6.00 D. The participants were scheduled for two days CL trial and were fitted with the best-fit SCL and TCL. After 4h of wear, they were assessed objectively for high contrast VA and subjective vision, comfort, and preference. RESULTS: The responses of 36 subjects (response rate 90%) with a mean age of 23.02±2.97y (range 18 to 33y) were analysed. One-line improvement of monocular VA in the logMAR chart was reported to TCL as compared to SCL (-0.044±0.06 vs 0.04±0.03 logMAR, P=0.01) but the binocular vision remained similar (-0.12±0.07 vs -0.14±0.04 logMAR, P=0.38). Subjects felt a noticeable difference in clarity when shifted to TCL as compared to the SCL. The satisfaction with vision (vision quality) was significantly better with TCL (P=0.03). The fatigue with TCL was graded less at 2.5±0.6, compared to SCL at 4.6±1.3 (P=0.04). Thirty-three participants (91.6%) preferred to use contact lens of which 26 participants (79%) preferred TCL. CONCLUSION: The findings suggest that VA and comfort are better with TCL as compared to SCL which is only observed if the patient was offered both offering SCL with spherical equivalent power alone as the first option can mislead the practitioner; TCL trial should be the first choice of the lens in low-to-moderate astigmatism.     

Management and treatment of bizarre open globe trauma in three steps:a case report

·This is a case presentation of a very bizarre open globe trauma with anterior segment foreign body-fishing hook stuck in the cornea and iris.Complications due to this kind of eye trauma might be very hazardous and with serious impact on visual function.We are representing our approach and experience of three step management of this kind of eye injury:first-extract the foreign body,close and reconstruct the eyeball,second-fight inflammation,and third-restore the visual function by cataract surgery.·
