Demographics and clinical presentation of patients with ocular disorders during the COVID-19 lockdown in India: A report

Ocular Trauma Trends during COVID-19 Pandemic

Background

The article aims to study the demographics and clinical characteristics of ocular trauma patients presenting to the Eye Casualty Clinic between COVID-19 and non-COVID-19 era in Ampang Hospital, Malaysia.

Methods

In this cross-sectional study, data of patients presented with ocular trauma injury to the Ampang Hospital during the COVID-19 era from 18 March 2020 to 17 September 2020 were retrieved and compared with the similar period of the previous non-COVID-19 era year.

Results

Among the total number of 453 patients, 76.82% (n = 348) were predominantly males. The commonest age group was between 21 years old-40 years old (49.45%, n = 224), and the commonest location of ocular trauma injury occurred at the workplace (38.19%, n = 173); welding was the commonest work-related injury (13.83% in 2019; 12.50% in 2020). Injury-to-treatment time was significantly longer during the COVID-19 era, where patients who sought treatment within a day of injury were 27.27% (n = 69) in 2019 and 18.50% (n = 37) in 2020 (P = 0.030). During the COVID-19 pandemic, patients with vision worse than 6/60 on presentation were higher at 8% compared with 3.56% before the COVID-19 pandemic (OR = 2.35; 95% CI: 1.01, 5.48; P = 0.047). Similarly, patients with a vision worse than 6/60 post-treatment during the COVID-19 period were significantly higher at 7.00% compared with 1.58% before the COVID-19 pandemic (OR = 4.72; 95% CI: 1.53, 14.62; P = 0.007).

Conclusion

The majority of ocular trauma cases in this study population were male adults between 21 years old and 40 years old, and welding was the commonest work-related injury. COVID-19 era has a higher percentage of patients presented with severe visual impairment, longer injury-to-treatment time and poorer post-treatment visual outcomes.

Year 1 of COVID-19 pandemic in India: Effect of lockdown and unlock on the presentation of patients with ocular and periocular tumors at a referral center

PURPOSE

The purpose of the study is to describe the impact of lockdown and unlock phases of the COVID-19 pandemic on the presentation of ocular and periocular tumors at a referral center in India.

MATERIALS AND METHODS

This cross-sectional, hospital-based study included 5811 patients presenting between March 25, 2017, and March 31, 2021. The data on the patients diagnosed with ocular and periocular tumors in one or both eyes presenting during the lockdown and unlock phases were compared with the respective time periods in the previous 3 years before COVID-19.

RESULTS

The patient numbers dropped by 85% (45/295) of pre-COVID-19 volumes during the lockdown phase. This was mainly because of a 33% reduction in patients requiring inter-state travel. There was complete recovery of the outpatient numbers to 105% (139/132) of pre-COVID-19 volumes by March 2021. This gradual incremental trend was seen in patients with malignant tumors (145%) and was lower in those with benign tumors (89%) than pre-COVID-19 volumes by March 2021. There was an increase in the patients presenting with malignant tumors (49%; P = 0.45) during the lockdown phase. The proportion of patients requiring inter-state travel showed a near-complete recovery to 88% of pre-COVID-19 distribution by March 2021.

CONCLUSION

The 1^st year of the COVID-19 pandemic saw a significant decline in the number of patients presenting with ocular and periocular tumors. There was an increase in the proportion of malignant tumors and a decrease in benign tumors during the lockdown phase. During unlock period, there was a near-complete recovery in the patients requiring inter-state travel to access eye care services.

Challenges in management of microbial keratitis during COVID-19 pandemic related lockdown: a comparative analysis with pre pandemic data

Purpose

To study the challenges of managing microbial keratitis(MK) during the COVID19 pandemic related lockdown and assess the outcomes of treatment at a tertiary cornea service.

Methods

Retrospective, non comparative study of electronic medical records of MK presenting to a network of four tertiary care cornea services. The medical history, presenting clinical features, microbiology work up and treatment outcomes were analyzed. The primary outcome measure was final outcome at last follow up. Secondary outcomes measures were non-compliance to treatment due to travel restrictions, therapeutic PKP not done due non availability of corneal tissues. Results- MK was noted in 330 eyes of 330 patients between April and May 2020. Of these 237(71.8%) were males. Median age was 45 years(IQR, 33-56). Low socioeconomic status noted in 102(30.9%). Patients travelling beyond the district from where the hospital was located comprised of 64.9%(n=214). At a median follow up of 32 days(IQR, 9-54), 118(35.8%) patients had resolved, with medical management, 73(22.1%) patients were under active treatment, 139(42.1%) were lost to follow up. Sixty-six patients(20%) were non-compliant to treatment of which 59 could not follow appointment schedule due to travel restrictions. Therapeutic PKP (TPK) was planned in 48/128 (37.5%) patients, but was performed in only 34/48 (70.8%) due to non-availability of donor corneas.

Conclusions

Abnormal social circumstances due to the COVID pandemic and the ensuing impediments to travel for access to health care affected compliance to treatment of ocular emergencies such as microbial keratitis.

Effect of the First Year of COVID-19 Pandemic on Ophthalmological Practice: A Multi-Centre Italian Study with a Focus on Medico-Legal Aspects

During the COVID-19 era, several restrictions on surgery have been imposed to reduce the infectious risk among patients and staff and further preserve the availability of critical care resources. The aim of the study was to assess their impact on the ophthalmological practice and its medico-legal implications. A retrospective review of electronic medical records of the ophthalmological departments of the University of Cagliari (SGD) and University Magna Græcia of Catanzaro (UMG), from 16 March 2020 to 14 March 2021 (52 weeks), were compared with data from the corresponding period of the previous year. Weekly data on the number and type of diagnoses and procedures performed were collected and analysed in relation to the weekly average of the total number of COVID-19 patients in intensive care units (ICUs) and inpatients in Sardinia and Calabria. Results showed a significant decrease in cataract surgery operations by 47% and 31%, respectively, in the SGD and UMG (p < 0.05) during the second semester of the year; this drop occurred at the same time as the increase in COVID-19 patients in ICU and those hospitalised in both regions. Additionally, anterior segment surgery decreased at the UMG by 30% (p < 0.05). Vitreoretinal surgery decreased by 27% at the SGD, differently increased amount 31.5% at UMG (p < 0.05). The pandemic had a dramatic impact on elective surgery in ophthalmology, quantifying the backlog is the first step in order to understanding the measures to be taken in near future.

COVID-19 Changed Prevalence, Disease Spectrum and Management Strategies of Ocular Trauma

The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted the health of people around the world and has reshaped social behaviors and clinical practice. The purpose of this perspective is to provide epidemiologists and clinicians with information about how the spectrum of ocular trauma diseases changed, as well as to optimize management for improving patient prognosis during this crisis. Analysis of current studies revealed that the prevalence of eye trauma decreased overall, with a trend of delayed medical treatment during the COVID-19 era. Irregular epidemic prevention and control measures, unprotected home activities, and unusual mental states are the main causes of ocular trauma. Strategies for reducing morbidity are also discussed, including popularizing the use norms of prevention and control supplies, taking heed to the safety of family activities, highlighting the special status of child protection, and paying attention to previous case data to implement region-specific precautions. The procedure of ophthalmological emergency and outpatient management should also be optimized, and mental health should be emphasized during this pandemic.

[Anterior eye segment damage in coronavirus infection (COVID-19)]

Conjunctivitis may appear as the first symptom of the coronavirus infection (COVID-19). In isolated cases, the lesion of the conjunctiva evokes a systemic infectious process. Currently, the conjunctiva is not considered as an area of long-term reproduction of coronavirus, and its damage is caused by hyperproduction of pro-inflammatory cytokines (especially IL-6); development of iridocyclitis and keratoconjunctivitis is also possible. Most often, local corticosteroids are used to treat these processes, although their use requires caution due to the risk of activating secondary infection (herpetic bacterial, fungal), which often develops as a result of immunodeficiency caused both by COVID-19 and the massive corticosteroid and antibiotic therapy employed when the course of the disease is severe. The severe condition of patients, the lung ventilation, and the prone position all contribute to corneal erosions, exposure keratopathy, pseudomonas aeruginosa keratitis and angle-closure glaucoma attacks. The risk of transmission of coronavirus infection during keratoplasty is estimated as minimal.

Waves of COVID-19 Pandemic: Effect on Ocular Surface Services at a Tertiary Eye Center in India

Objective

To describe the impact of lockdown and unlock phases of the coronavirus disease 2019 (COVID-19) pandemic on the ocular surface services at a tertiary eye care center in India.

Methods

This cross-sectional hospital-based study included 18,127 patients presenting between March 25, 2017, and July 31, 2021. A comparative analysis of the data was performed on the patients diagnosed with ocular surface disorders (allergic eye disease, cicatrizing conjunctivitis, dry eye, limbal stem cell deficiency, and ocular surface burns) and ocular surface surgeries (amniotic membrane grafting, keratoprosthesis, mucous membrane grafting, and simple limbal epithelial transplantation) presenting during the lockdown and unlock phases and the previous three years before COVID-19.

Results

The outpatient numbers dropped to 18.6% (172/954) and surgeries performed decreased to 2.8% (13/461) of pre-COVID-19 volumes during the lockdown phase. This was mainly because of a 74% reduction in the proportion of patients requiring inter-state travel to this tertiary care referral center. There was a gradual recovery of the outpatient numbers to 70.8% (565/798) and surgeries performed to 85.8% (109/127) of pre-COVID-19 volumes by February-March 2021. This gradual incremental trend was seen across all diagnoses and surgeries except for ocular burns, which showed an initial spike in the month of May followed by another sharp increase by the month of September that coincided with the gradual ease of lockdown regulations. The proportion of patients requiring inter-state travel showed an incomplete recovery to 77.2% of pre-COVID-19 distribution by March 2021.

Conclusion

The first year of the COVID-19 pandemic saw a drastic reduction in the outpatient numbers and surgical volume in the lockdown phase, which gradually recovered during the unlock period. However, the impact of the second wave was significant and is showing a gradual recovery in patients accessing eye care services.

Effect of Lockdown and Unlock Following COVID-19 on the Presentation of Patients With Endophthalmitis at a Tertiary Eye Center Over One Year

Introduction Endophthalmitis is an emergency where patients need immediate intervention to salvage both vision and the globe. Regular follow-up care and close monitoring of the status of the patient are crucial in determining the final outcomes of the treatment. While there is ample literature on the epidemiology and demography of endophthalmitis across the globe, no information exists on the effect of the coronavirus disease 2019 (COVID-19) pandemic on the presentation patterns of endophthalmitis. Objectives To describe the impact of the lockdown and unlock phases of the COVID-19 pandemic on the presentation of endophthalmitis at a tertiary eye care center in India. Methods This cross-sectional hospital-based study included 1,253 patients presenting between March 25, 2017, and March 31, 2021. The data on the patients diagnosed with endophthalmitis in one or both eyes presenting during the lockdown and unlock phases were compared with the respective time periods in the previous three years before COVID-19. Results The patient numbers dropped to 42.18% (27/64) of pre-COVID-19 volumes during the lockdown phase. There was a near-complete recovery of the outpatient numbers to 85.71% (26/30) of pre-COVID-19 volumes by March 2021. This gradual incremental trend was seen in etiology due to post-surgery (88%) and endogenous (159%) infections while post-traumatic (67%) and post-infection (0%) infections were lower than pre-COVID-19 volumes by March 2021. There was a slight increase in the proportion of patients with acute endophthalmitis (88.93% vs 86.20%; p=0.76) presenting during the COVID-19 phase as compared to the pre-COVID-19 phase. The proportion of patients requiring inter-state travel showed complete recovery to 107% of pre-COVID-19 distribution by March 2021. Conclusion The first year of the COVID-19 pandemic saw a decline of over half the number of patients with endophthalmitis accessing eye care services. There was an increase in the presentation of endogenous endophthalmitis and a decrease in post-traumatic forms. Patients requiring inter-state travel recovered during the unlock phase.

Surgical performance and the positivity rate for novel coronavirus (severe acute respiratory syndrome coronavirus 2) in an ophthalmic setup during the coronavirus disease 2019 pandemic

AIM:

To describe, the impact of ongoing coronavirus disease 2019 (COVID-19) pandemic on ophthalmic surgeries at a tertiary eye care center of East India during and after the lockdown, and the positivity rate for novel coronavirus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]).

MATERIALS AND METHODS:

A retrospective study of all ophthalmic surgeries performed during and after lockdown from April 1, 2020 to August 31, 2020, with comparison to the corresponding period in the previous year (2019) was done. Eligible patients were tested for novel coronavirus (SARS-CoV-2) preoperatively as per the institutional protocols.

RESULTS:

A total of 569 surgeries were performed during the study period compared to 3458 performed in 2019, (P = 0.00001). The maximum number of surgeries were performed in June (191, 33.57%) and July (189, 33.22%) and in the subspecialty of vitreo-retina (337, 59.23%) followed by cataract (101, 17.75%). The most common vitreoretinal procedures were intravitreal injections (223, 66.17%) and retinal detachment surgery (56, 16.62%). Emergency surgeries performed were 30 (5.275%) compared to 76 (2.20%) during the same duration in the previous year (P = 0.00004). Ninety-four (16.52%) cases were screened for COVID-19. A total of 10 (10.64%) cases tested positive for SARS-CoV-2. Only one of these cases was symptomatic.

CONCLUSION:

There was a drastic decline in the number of both elective and emergency surgeries during and after the lockdown period of the COVID-19 pandemic when compared to the corresponding previous year duration. The maximum number of surgeries was performed in the vitreoretinal subspecialty. The positivity rate for SARS CoV-2 amongst the patients tested was 10.64% and most of these patients were asymptomatic.

Effect of COVID-19 Pandemic on Presentation of Patients With Diabetic Retinopathy in a Multitier Ophthalmology Network in India

OBJECTIVE

This study aimed to describe the demographics and clinical profile of patients with diabetic retinopathy (DR) presenting during the novel coronavirus disease 2019 (COVID-19) lockdown and unlock phases in India.

METHODS

This hospital-based cross-sectional study included patients presenting from March 25, 2019, to March 31, 2021. All patients who presented with DR were included as cases. The data were collected using an electronic medical record system.

RESULTS

In total, 88,012 patients diagnosed with retinal diseases were presented to the network and included for analysis. There were 21,271 (24%) DR patients during the study period and the majority were men (71%) from the urban area (45%). An increasing number of patients with proliferative DR (56%), sight-threatening DR (79%), need for vitreoretinal procedures (31%), and intravitreal injections (19%) were seen during the lockdown (phase one-four). There was a significant increase in the number of patients with blindness in pre-lockdown (20%), lockdown (32%), and post-lockdown (26%). Patterns of sight-threatening DR and blindness were similar in both fresh and follow-up patients.

CONCLUSION

The presentation of DR patients in hospital is evolving because of the COVID-19 pandemic. The footfalls of patients during the unlock (phase 1-10) regained to two-thirds of the pre-COVID-19 level. There was an increase in patients with sight-threatening DR and the need for vitreoretinal surgery and intravitreal injections during the lockdown (phase 1-4).

Changing trend in the pattern of ocular diseases in patients attending ophthalmology department of a teaching institute in North India during COVID-19 pandemic

Purpose:

The objective of this study is to report the changing trend in ocular diseases during COVID-19 pandemic.

Methods:

A retrospective review of patients attending the ophthalmology department of a teaching institute was conducted. We studied the 3 months of the COVID period from April 2020 to June 2020. For comparison, we took the corresponding period of April 2019 to June 2019. Data were collected from the medical record section of the Hospital.

Results:

Overall, 876 patients presented during the 2020 period compared to 7,242 patients in the 2019 period. Percentage of female patients decreased from 53.1% to 49.1% in the 2020 period (P = 0.0251). There is significant decrease in pediatric group in the 2020 period (P < 0.0001). In the 2019 period, refractive errors was the most common (57.6%) followed by cataract (12.29%), allergic conjunctivitis (3.82%), diabetic retinopathy (3.37%). While in the 2020 period refractive errors, constitute 22.37%, followed by allergic conjunctivitis (8.56%), scleritis/episcleritis (7.19%), dry eyes (7.08%), infective conjunctivitis 6.85%), anterior uveitis (6.74%). In the 2020 period, there was significant decrease (P < 0.00001) in the percentage of refractive errors, cataract and diabetic retinopathy, and significant increase in painful symptomatic conditions. The features of ocular trauma in the two study periods were also quite different.

Conclusion:

There is significant decrease in patients of curable/avoidable blindness. We should be ready for the increase burden of curable/avoidable blindness and should plan various strategies to overcome the potential backlog of blindness.

Impact of COVID-19 related national lockdown on care of corneal transplantation patients at a tertiary eye care centre in India

Purpose

To study impact of COVID-19 related national lockdown on care of corneal transplantation patients at a tertiary eye centre in Andhra Pradesh state of South India.

Methods

Cross-sectional questionnaire-based study conducted at tertiary eye care centre in Andhra Pradesh state of South India, included 109 patients who underwent keratoplasty(full thickness or partial thickness) at our centre and who came for follow-up visit after lockdown. Factors such as type, indication, number of keratoplasties in the operated eye, and unusual clinical outcomes identified during visit after the lockdown, were studied. Uncorrected visual acuity, best corrected visual acuity, clarity of graft, graft-host junction apposition, intactness of sutures, intraocular pressure and disc status were compared on visits made before and after lockdown.

Results

During lockdown, 77.1% patients were properly using medications that was significantly (P = 0.0003) lower than that of before the lockdown (90.8%). After the lockdown, 82.3% patients were using medications properly that was comparable (P = 0.11) to that of during the lockdown (77.1%). The proportion of eyes with clear grafts and intact sutures decreased significantly after lockdown. The unusual outcomes observed after the lockdown were graft failure (36.7%), graft edema (11%), graft infiltrate(5.5%), phthysis bulbi (1.85%) and edematous graft cleared in eyes 3.7% eyes.

Conclusion

We noted significant drop in usage of medications from 91% before lockdown to 77% during lockdown and maintained at 83% after lockdown. Edematous grafts increased from 41% before lockdown to 54% after the lockdown. Intactness of sutures decreased from 82% before lockdown to 69% after lockdown.

The impact of COVID-19 "Unlock-I" on L V Prasad Eye Institute Network in Southern India

Purpose:

The aim of this study was to report on the impact of COVID-19 “Unlock-I” on Network of Eye Centers in Southern India.

Methods:

Our eye health pyramid model has a network of eye care centers in four Indian states. The network constitutes a center of excellence (CoE) at the apex followed by tertiary care centers (TC) located in urban areas, secondary care centers (SC), and primary care vision centers (VC) at the base located in rural areas. We collected data on patients seen between June 2019 and June 2020, which included age, gender, total patients seen (new or follow-up), and socioeconomic status (paying and nonpaying). A comparative study was done between the data for outpatients and surgeries performed pre-COVID-19 and during Unlock-I in COVID-19 period.

Results:

There was a 36.71% reduction in the overall outpatients seen in June 2020 (n = 83,161) compared to June 2019 (n = 131,395). The reduction was variable across different levels of the pyramid with the highest reduction in CoE (54.18%), followed by TCs (40.37%), SCs (30.49%) and VCs (18.85%). Similar pattern was seen for new paying patients with the highest reduction in CoE (54.22%), followed by TCs (25.86%) and SCs (4.9%). A 43.67% reduction was noted in the surgeries performed in June 2020 (n = 6,168), compared to June 2019 (n = 10,950). Reduction in paying services was highest in CoE (47.52%), followed by TCs (15.17%) and SCs (4.87%). There was no significant change in the uptake of services by gender in the network.

Conclusion:

Highest reduction in patient footfalls during “Unlock-1” was noted in urban centers. Going forward, there is a need to develop strategies to provide eye care closer to the doorsteps.

COVID-19 pandemic and lockdown: Changing trends in Ophthalmology for in-patient and emergency services

Purpose:

The aim of this study was to evaluate the changing trends in terms of patient load, presenting complaints, surgical procedures and resource utilization in a multispeciality tertiary care hospital after lockdown due to COVID-19.

Methods:

Retrospective data were collected from Ophthalmology in-patient and emergency services of a government medical college and multispecialty tertiary care hospital in North India. Data pertaining to patient census, presenting complaints, surgical procedures and resource consumption were compared in the 6-month period (March 25 to September 30, 2020) following national lockdown and subsequent gradual unlock to data of same time period last year.

Results:

A total of 1152 new patients visited Ophthalmology emergency service, whereas 324 sought tele-ophthalmology consultation. Majority were males (61.8%, n = 712), whereas average age of presentation was 34 ± 7.2 years. The number of patients seeking emergency ophthalmic care reduced by 23.9% in the current year, in-patient record reduced by 96.53% and number of surgeries reduced by 98.13%. Tele-ophthalmology services comprised 21.95% of the total patient load. Use of triple layered surgical masks increased by 85.7%, use of disposable gloves increased by 89.5% but interestingly the availability of chlorhexidine hand rub fell by 15.9%, in the current year compared to last year.

Conclusion:

COVID-19 pandemic and lockdown have reduced the number of patients visiting tertiary health care facility for ophthalmic care. As manpower and resource consumption has increased, smart management is needed to tackle the current scenario efficiently. Tele-ophthalmology must be promoted and we must understand the changing trends to plan for the future accordingly.

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.

Impact of COVID-19-related lockdown-I on a network of rural eye centres in Southern India

Purpose:

With the outbreak of coronavirus disease 2019 (COVID-19), India went for lockdown-I on March 23, 2020. In this article, we report on the demographic profile and ocular disorders from our 20 rural eye centres during lockdown-I and its comparison with the pre-lockdown period.

Methods:

A retrospective analysis was conducted for all patients who visited or had teleconsultations at the 20 rural centres in our network between March 23 and April 19, 2020. Demographic and clinical details were collected from electronic medical records (EMR). Subspecialty was decided based on the diagnosis. Patients who needed advanced care were referred to the higher tertiary centres. We report the profile of patients seen and managed at the rural centres and the reasons for referrals. We also compare the data with the pre-lockdown period.

Results:

During the lockdown-I period, a total of 263 patients were treated including 48 teleconsultations (18.25%). The mean age was 48.16 years (SD: 19.53 years). There were 118 females (44.87%). As compared to pre-lockdown, during the lockdown, the patient visits were highest in the cornea and anterior segment specialty with 114 patients (43.35%), including conjunctivitis (n = 25; 22.32%). Of the 263 patients, 24 patients (9.12%) were referred to tertiary centres. This includes 6/27 (22.22%) patients of microbial keratitis. As compared to this, during pre-lockdown, 28,545 patients were seen. The mean age was 49.03 years (SD: 19.24 years). There were 14,927 (52.29%) females. The referral was 1525 (5.34%), including 34/249 (13.65%) of those with keratitis.

Conclusion:

Lockdown-I had significantly impacted patient care in rural areas. As compared to the pre-lockdown period, during the lockdown, there was an issue with access to services by females. Despite a higher number of specialty patients (including emergencies) visiting during the lockdown, 91% of the patients who visited rural centres could be managed locally, avoiding long-distance travel.

Managing vitreoretinal surgeries during COVID-19 lockdown in India: Experiences and future implications

Purpose:

The study aims to describe the clinical and demographic profile of patients who required vitreoretinal surgeries during the novel coronavirus disease-2019 (COVID-19) lockdown in India. It also reports our operating protocols and initial experience while performing vitreoretinal surgeries during COVID-19 times at a government tertiary eye care hospital.

Methods:

This is a retrospective cross-sectional observational study of patients requiring emergent/urgent vitreoretinal surgeries between March 25, 2020 and May 31, 2020. A modified working protocol focussing on the enforcement of standard COVID-19 precautions, OT sterilization, and formation of dedicated infection control and disease surveillance committee was adopted. Patients underwent standard vitreoretinal procedures under general/local anesthesia. Relevant demographic and clinical data were recorded and analyzed. Surveillance data of healthcare workers (HCW) was also analyzed.

Results:

Eighty six patients were considered for vitreoretinal surgery in this period. Finally, 83 patients underwent surgery. The mean age of the patients was 38.4 ± 20.1 years (Range, 1 month - 75 years). Majority of them were males (66%) and adults (82.6%). Majority of them came from nearby hotspot areas. Most common indications were acute retinal detachment (38.5%) and diabetic vitrectomies (22.9%). Trauma-related cases (14.4%) were less. Surgery was deferred in 3 patients who turned out to be COVID-19 positive. 4 HCWs were quarantined but none of them developed COVID-19 disease.

Conclusion:

During COVID-19 lockdown, vitreoretinal surgeries were most commonly performed for retinal detachment and diabetic complications. Proper implementation of infection control protocols helps in delivering adequate patient care while ensuring the safety of caregivers during this pandemic.
