Ophthalmology Practice-Related Factors and Patient Loyalty: Mediating Role of Patient Satisfaction

Background

In the current period, competition among the healthcare sector has increased and healthcare providers try to get loyalty and satisfy the patients by establishing different strategies.

Purpose

: This current study aims to discover ophthalmology practice-related factors and patient loyalty and to analyze the mediating role of patient satisfaction in private ophthalmology services in various private centers in the Kingdom of Saudi Arabia.

Methods

: The nature of the study is quantitative, and data is collected with a questionnaire. We used a pre-tested questionnaire that was divided into different sections assessing ophthalmology practice-related factors, patient satisfaction, and patient loyalty. These were measured using a 5-point Likert scale, focusing on financial aspects, access to facilities, staff services, and ophthalmologist services. Further, the smartPLS technique was used to extract the results by using SmartPLS.

Results

: The analysis sample size consisted of 323 participants from Saudi Arabia. The results found that ophthalmologist service has a positive relationship with patient satisfaction (β= 0.369, p = 0.000) as well as patient loyalty (β= 0.234, p = 0.004), but there are some ophthalmology practice-related factors such as financial aspects, access and facilities, and staff service, which showed no relationship with patient loyalty but a positive relationship with patient satisfaction. Further analysis found that patient satisfaction as a mediator has a positive relationship between ophthalmology practice-related factors, namely, ophthalmologist service (β= 0.228, P= 0.000), financial aspects (β= 0.102, p = 0.019), access and facilities (β= 0.109, p =0.000), and staff service (β= 0.188, p = 0.000) with patient loyalty.

Conclusion

: The present study findings reveal the importance of focused patient satisfaction improvements in enhancing patient loyalty within ophthalmological clinic settings in Saudi Arabia. Furthermore, we recommend future exploratory prospective research to find the satisfaction and loyalty factors that change over a period of time.

Impact of COVID-19 pandemic on retinopathy of prematurity services in low resource settings

BACKGROUND AND OBJECTIVES

Retinopathy of prematurity is an increasingly important cause of blindness in children in low- and middle-income countries. Timely screening and treatment greatly reduce blindness. This study assessed the impact of the COVID-19 pandemic on ROP services in low- and middle-income countries.

METHODS

An online survey with closed and open-ended questions in Microsoft Teams was sent to 304 ophthalmologists providing screening, treatment and/or vitreoretinal services (January 15 to March 12 2021). Categories were used to report impact on services. 28 participants were purposively selected for interview.

RESULTS

184/201 completed forms from 32 countries were received. Two thirds of participants worked in government facilities and 45.6% were paediatric ophthalmologists. A moderate to severe impact was reported by 13% for screening, 9% for treatment and 16% for vitreoretinal surgery with some variation between government, private and not-for-profit sectors. 22% thought services would take a year to recover. Fifteen ophthalmologists from 12 countries were interviewed. Many reported fewer neonatal admissions, and several reported more ROP blind infants once restrictions lifted. Themes associated with services continuing included limited lockdown, autonomy and flexibility, commitment, advocacy and technology. Themes associated with a negative impact include fear and panic, closure of facilities, COVID infection or quarantining of health workers and parents, lack of transport and exacerbation of poverty.

CONCLUSIONS

The COVID pandemic had a very variable impact on the provision of ROP services. In some countries where the impact was great, more infants may have become blind from ROP. Lessons can be learnt for planning pandemic preparedness.

Reducing the Impact of the COVID-19 Pandemic on Retinopathy of Prematurity Screening: Successful Strategies Learnt from a Multi-Center Tele-Medicine Program in India

PURPOSE

Control of blindness due to retinopathy of prematurity (ROP) requires timely screening and treatment within 48-72 h. Anticipating that the coronavirus disease 2019 (COVID-19) pandemic would disrupt ROP services, we devised strategies ''on-the''-go"" to ameliorate this possiblity. We describe the successful outcomes of this approach in preventing infant blindness during the pandemic.

METHODS

Data on the number of preemies recruited, screened and treated in the Karnataka Internet-assisted Diagnosis of Retinopathy of Prematurity (KIDROP) program were collected in a retrospective (2019, interval 1) - prospective (2020, interval 2) manner. We summarize 10 key strategies that were developed as we faced logistic, operational and implementation challenges. These included pragmatic methods of enhancing enrolment, transporting for screening and ensuring timely treatment in the outreach.

RESULTS

The total number of ROP screening sessions was 20,598 (7,197 new) and 14,371 (5,773 new) during interval 1 and 2 respectively. Of these, 166 (2.3%) and 157 (2.7%) infants required treatment during interval 1 and 2 respectively. All infants needing treatment during the COVID period, were treated on time which was possible due to successful implementation of the 'on-the-go' strategies throughout the state of Karnataka. The fiscal equivalent of the blindness prevented during this period is USD 15.6 million.

CONCLUSION

The greater decline in the number of ROP screening episodes in neonatal units in government hospitals was because several were converted to 'COVID only" hospitals. KIDROP's multi-zonal, decentralized strategy, which uses non-physician-based imaging in a telemedicine network, ensured that essential ROP services continued even during the lockdown.

Impact of COVID-19 Pandemic on Retinopathy of Prematurity Services in the Indian Public Healthcare System

Purpose

To analyze the impact of the COVID-19 pandemic on the retinopathy of prematurity (ROP) services at Special Newborn Care Units (SNCUs), which provide care for sick neonates in the Indian public healthcare system.

Methods

A retrospective chart analysis of 508 babies screened for ROP at two SNCUs in West Bengal (India). We compared the data from the lockdown period (April, 2020-June, 2020; study arm) with the same period of the preceding year, 2019 (control arm).

Results

Out of the 508 babies, 187 were screened during the lockdown and 328 during 2019. The odds of developing ROP were 2.08 times (95% CI:1.25-3.48; P=0.002) higher during the lockdown period (35/187 babies; 18.72%) as compared to the previous year (34/328 babies; 10.37%). Also, the risk of sight-threatening ROP (ST-ROP) increased significantly during the lockdown (12/35 ROP babies; 34.29%) compared to the previous year (4/34 ROP babies; 11.76%) (odds ratio: 3.9; 95% CI:1.1-13.7; P=0.015). Notably, all babies with ROP during the lockdown presented more than 30 days after birth, compared to none in the previous year. All babies requiring laser therapy recovered completely in both groups.

Conclusion

An increased odds of developing ROP, including ST-ROP, was observed during the COVID-19 pandemic. Delayed ROP screening, which was noted in all study eyes, can have a detrimental effect on long-term visual prognosis. The findings of our research call for modifying the present healthy policy framework to make it more adaptable to disruptions in healthcare services, given the cyclical nature of the worldwide COVID-19 pandemic.

Challenge Accepted: Retinopathy of Prematurity (ROP) During COVID-19

The World Health Organization has identified retinopathy of prematurity (ROP) as one of the emerging causes of preventable childhood blindness in developing and middle-income countries. It is becoming a major public health problem in developing countries like India and China. ROP blindness in India is increasing due to the highest number of preterm births in the world, suboptimal neonatal care, lack of awareness, screening programs and treatment not in place, and increasing numbers of neonatal intensive care units (NICUs) and special newborn care units (SNCUs) opening all over the country without appropriate ophthalmic care. On top of it, heavier and late preterm babies are developing severe ROP due to the variable quality of neonatal services and insufficient optimal eye care in the NICU and SNCU. The situation become more precarious during the coronavirus disease 2019 (COVID-19) pandemic, and it became a challenge to motivate health workers and parents to keep the screening and treatment of ROP babies in place.

An insight into the altered ophthalmic dynamics during the COVID-19 pandemic

Purpose

The objective of this survey-based study was to examine the effects of personal protective measures taken at the level of instrument and surgeon during the pandemic on the optics in ophthalmology.

Methods

The study involved an online questionnaire of 24 questions which was distributed to ophthalmologists practicing in several hospitals, including residents and fellows undergoing training in ophthalmology in India. The responses were collected through an online data collection tool (Google forms). The participants could choose from multiple options provided to them in each question.

Results

A total of 285 participants out of 296 had used modified methods for examining and performing surgical procedures during the pandemic, while 78.7% (265) of the participants acknowledged having encountered difficulty in interpreting the ocular findings of patients while examining in personal protective equipment. Moreover, 58.7% (198) of our study respondents also reported that there was significant worsening of the quality of ophthalmological examination with pandemic-appropriate measures and 84.8% (286) of our study participants also felt that these measures have significantly added to the time of examination, hence increasing the risk of exposure to both patient and doctor.

Conclusion

The workplace study has highlighted the crucial aspects of optics in ophthalmology during the pandemic. The protective measures taken during the pandemic have significantly worsened the quality of ophthalmological examination and increased the time taken to perform outpatient department-based and surgical procedures in ophthalmology.

Door-to-door Screening as a New Model Augmenting School Eye Screening: Reaching Out to School Age Children in the Midst of a Pandemic

PURPOSE

Explore door-to-door eye screening in India as a model to reach school age children in need of eye care, especially during school closures due to the Covid-19 pandemic.

METHODS

Children between 5 and 18 years were screened in an urban-slum of Delhi from September 2020 to March 2021. Screening included capturing ocular complaints, visual acuity and conducting a torchlight examination. Children with any eye-related complaints, gross abnormality or a LogMAR acuity of more than 0.2 in either eye were referred to the nearby vision centre. Data were disaggregated by gender and age group. Reporting after referral and proportion of true positives referrals were used to assess the model.

RESULTS

32,857 children were screened. 55% were boys. Only 917 children (2.8%) had previous eye examinations. 1814 (5.5%) children were referred. Overall compliance rate amongst those referred was 59% (1070 of 1814) and compliance was significantly higher (72%) amongst those referred with poor vision as compared to those with only ocular morbidities (38%). Overall compliance was significantly higher amongst older age group (64% vs 50%) and amongst girls than boys (61% vs 56%). 3.9% children were detected with refractive error (RE) and 2.5% with uncorrected RE which was significantly higher in girls and in older age group. Of 1070 children reporting after referral, 85% had confirmed diagnosis for RE or other ocular pathology.

CONCLUSION

Door-to-door screening had good referral compliance and positive predictive value. We recommend this model as a supplement to school screening especially in regions with low enrolment and high absenteeism in schools.

Conjunctival Swab Findings in 484 COVID-19 Patients in Four Hospital Centers in Slovakia

Since 2020, the COVID-19 (Coronavirus Disease 2019) has quickly become a worldwide health problem. Ophthalmologists must deal with symptoms as well. For the positive detection in the conjunctival sac swab in COVID-19 patients hospitalized in Slovakia during March 2021 in four hospital centers, we used a test based on a polymerase chain reaction (PCR). In a group of 484 patients, 264 males (55%) and 220 females (45%) with clinical symptoms were identified with COVID-19 as a clinical diagnosis. The PCR test swab results from the conjunctival sac taken on the same day were positive in 58 patients (12%), 31 males (with a mean age of 74.6 ± 13.59 years) and 27 females (with a mean age of 70.63 ± 14.17 years); negative in 417 patients (86%); and 9 patients (2%) had an unclear result. The cycle threshold values comparing the nasopharynx and conjunctiva were also different in the group of all patients divided by age and gender. In COVID-19 patients the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was detectable using PCR test in the nasopharynx but also in the conjunctival sac swab, where the positivity rate was only 12%.

Knowledge, Attitude, and Practice Patterns Related to Digital Eye Strain Among Parents of Children Attending Online Classes in the COVID-19 Era: A Cross-sectional Study

PURPOSE

To assess the prevalence of digital eye strain among children and extrapolate the association between knowledge, attitude, and practice patterns related to device use during the coronavirus disease 2019 (COVID-19) lockdowns.

METHODS

A cross-sectional, descriptive, questionnaire-based analysis was done to assess the knowledge, attitude, and practice patterns related to digital device use among parents of children attending online classes.

RESULTS

A total of 305 responses were obtained. The most common reason for device use was online classes (288 children; 94.4%) and the most common mode was smartphone (263 children; 86.3%). The prevalence of digital eye strain was 64.6%. The mean knowledge score was 48.5 ± 5.1, the mean attitude score was 26.7 ± 4.9, and the mean practice score was 17.8 ± 3.5. The difference between knowledge, attitude, and practice scores among parents of children with and without glasses was not statistically significant (P = .580, .521, and .503, respectively). A direct correlation was found between the knowledge and practice scores (P = .002), but attitude scores did not show a significant correlation (P = .712).

CONCLUSIONS

Digital devices have been a boon to continue education during the ongoing COVID-19 pandemic. This study reveals a large knowledge gap among parents related to safe digital device use. Further, there is a need to adopt methods that would help spread awareness to the masses about the effects of excessive screen time in children in the form of digital eye strain and myopia and the corrective measures to avoid the same.

Altered Ocular Surface Health Status and Tear Film Immune Profile Due to Prolonged Daily Mask Wear in Health Care Workers

Prolonged daily face mask wearing over several months might affect health of the ocular surface and is reported to be associated with complaints of discomfort and dry-eye-like symptoms. We studied the ocular surface clinical parameters, tear soluble factors and immune cell proportions in ophthalmologists practicing within similar environmental conditions (n = 17) at two time points: pre-face-mask period (Pre-FM; end of 2019) and post-face-mask-wearing period (Post-FM; during 2020 COVID-19 pandemic), with continuous (~8 h/day) mask wear. A significant increase in ocular surface disease index (OSDI) scores without changes in tear breakup time (TBUT), Schirmer’s test 1 (ST1) and objective scatter index (OSI) was observed Post-FM. Tear soluble factors (increased—IL-1β, IL-33, IFNβ, NGF, BDNF, LIF and TSLP; decreased—IL-12, IL-13, HGF and VEGF-A) and mucins (MUC5AC) were significantly altered Post-FM. Ex vivo, human donor and corneoscleral explant cultures under elevated CO₂ stress revealed that the molecular profile, particularly mucin expression, was similar to the Post-FM tear molecular profile, suggesting hypercapnia is a potential contributor to ocular surface discomfort. Among the immune cell subsets determined from ocular surface wash samples, significantly higher proportions of leukocytes and natural killer T cells were observed in Post-FM compared to Pre-FM. Therefore, it is important to note that the clinical parameters, tear film quality, tear molecular factors and immune cells profile observed in prolonged mask-wear-associated ocular surface discomfort were distinct from dry eye disease or other common ocular surface conditions. These observations are important for differential diagnosis as well as selection of appropriate ocular surface treatment in such subjects.

Preferred practice guidelines for retinopathy of prematurity screening during the COVID-19 pandemic

Retinopathy of prematurity (ROP) is the leading cause of preventable infant blindness in the world and predominantly affects babies who are born low birth weight and premature. India has the largest number of surviving preterm births born annually. ROP blindness can be largely prevented if there is a robust screening program which detects treatment requiring disease in time. ROP treatment must be provided within 48 h of reaching this threshold of treatment making it a relative emergency. During the severe acute respiratory syndrome-coronavirus disease 2019 pandemic in 2020 ROP screening was disrupted throughout the world due to lockdowns and restriction of movement of these infants, their families, specialists and healthcare workers. The Indian ROP Society issued guidelines for ROP screening and treatment in March 2020, which was aimed at preserving the chain-of-care despite the potential limitations and hazards during the (ongoing) pandemic. This preferred practice guideline is summarized in this manuscript.

Noninvasive Visualization of the Tear Film Microaerosol During Noncontact Tonometry Measurements

PURPOSE

To investigate the aerosol generation by a noninvasive real-time observation device and assess the conditions relating to aerosolization during intraocular pressure (IOP) measurements using a commercial noncontact tonometer (NCT).

STUDY DESIGN

Prospective experimental and healthy eye studies.

METHODS

In an initial experimental study, we devised a model mannequin eye to investigate how air puff pressure and IOP of the eye affected aerosol generation. In the human study including 20 healthy volunteer control subjects, the number of tear aerosol particles generated at 20 and 40 mm Hg air puff pressures with and without eye drop was investigated. The recorded aerosol visualization video was analyzed and the number of aerosol particles generated in 5 seconds after IOP measurement was measured.

RESULTS

The experimental and human studies confirmed the aerosol generation during NCT measurements. In the experimental study, when the air puff pressures were set at 20 and 40 mm Hg, a lower IOP (5 mm Hg) generated significantly more aerosols than a higher IOP (25 mm Hg) (20 mm Hg, P = .0159; 40 mm Hg, P = .0079). There was also a significant positive correlation between the air puff pressure and the number of aerosol particles in both high- and low-IOP eyes (P < .001). At an air puff pressure of 40 mm Hg, the amount of aerosol generated was significantly higher with eye drop than without eye drop (P = .047).

CONCLUSIONS

NCT generates significant aerosolization from the tear film, the amount of which is determined by the IOP and the air puff pressure and the presence of eye drop use before the measurements.

Non-mydriatic fundus photography as an alternative to indirect ophthalmoscopy for screening of diabetic retinopathy in community settings: a comparative pilot study in rural and tribal India

OBJECTIVES

The impending and increasing prevalence of diabetic retinopathy (DR) in India has necessitated a need for affordable and valid community outreach screening programme for DR, especially in rural and far to reach indigenous local communities. The present study is a pilot study aimed to compare non-mydriatic fundus photography with indirect ophthalmoscopy for its utilisation as a feasible and logistically convenient screening modality for DR in an older age, rural, tribal population in Western India.

DESIGN AND SETTING

This community-based, cross-sectional, prospective population study was a part of a module using Rapid Assessment of Avoidable Blindness and DR methodology in 8340 sampled participants with ≥50 years age. In this study, the diabetics identified were screened for DR using two methods: non-mydriatic fundus photography on the field by trained professionals, that were then graded by a retina specialist at the base hospital and indirect ophthalmoscopy by expert ophthalmologists in the field with masking of each other's findings for its utility and comparison.

RESULTS

The prevalence of DR, sight threatening DR and maculopathy using indirect ophthalmoscopy was found to be 12.1%, 2.1% and 6.6%, respectively. A fair agreement (κ=0.48 for DR and 0.59 for maculopathy) was observed between both the detection methods. The sensitivity and specificity of fundus photographic evaluation compared with indirect ophthalmoscopy were found to be 54.8% and 92.1% (for DR), 60.7% and 90.8% (for any DR) and 84.2% and 94.8% (for only maculopathy), respectively.

CONCLUSION

Non-mydriatic fundus photography has the potential to identify DR (any retinopathy or maculopathy) in community settings in Indian population. Its utility as an affordable and logistically convenient cum practical modality is demonstrable. The sensitivity of this screening modality can be further increased by investing in better resolution cameras, capturing quality images and training and validation of imagers.

Challenges and impact of COVID-19 lockdown on Indian optometry practice: A survey-based study

PURPOSE

The Indian government announced a nationwide lockdown as a preventive measure to control the prevailing COVID-19 pandemic. This survey was developed and conducted to assess the impact of lockdown on Indian optometry practice.

METHODS

A survey questionnaire was designed and circulated across the optometrists practicing in India through multiple social media platforms. All the data were extracted and only valid response were analyzed and reported.

RESULTS

A total of 691 optometrists participated in the survey. Most of the participants (22.25%) were in private practice followed by academics (14.89%). Among the valid responses collected, it was found that 43.37% of the respondents were consulting patients during the lockdown. Of these, 27.17% of optometrists were examining infectious cases and 48.68% were examining all the patients who came for consultation. Approximately 50.94% of the participated optometrist had begun telephonic/e‑mail/video consultations. In addition, 64.48% reported that optometrists were at an equal risk of clinching COVID‑19 on comparison with other domains during patient examination. Nearly 30.44% respondents felt that optometrists would face challenges in approaching the patient post COVID-19 considering the close working distance.

CONCLUSION

A proportion of optometrist have switched to some form of teleconsultation in order to aid patients during this prevailing pandemic. Regulatory bodies should issue appropriate guidelines regarding the safe optometry practice for the betterment of both patient and practitioners during face-to-face consultation.

Coronavirus disease (COVID-19) and conjunctival sac swab findings

Background

The purpose of this article is to evaluate the positivity of conjunctival sac swab by PCR (Polymerase chain reaction) test in COronaVIrus Disease 19 (COVID-19) patients.

Methods

Inclusion criteria of our study were COVID-19 patients hospitalized during March 2021 in inpatient wards at University Hospitals in towns Bratislava and Zilina, Slovakia. The conjunctival sac swabs collected by four ophthalmologists were stored for 24 h, then analyzed in the laboratory of the Department of Microbiology and Immunology, Jessenius Faculty of Medicine in Martin, Comenius University, Slovakia. The sampling apparatus, used for conjunctival sac swab, was the Dacron polyester swab.

Results

We examined one group of 302 COVID-19 patients, 168 Male (56%) and 134 Female (44%). The patients’ mean age was 66.3 ± 13.66 years, ranging from 25 to 96 years, and the mean length of hospital stay in our patients with a nasopharyngeal positive PCR test was 7.33 ± 4.76, from 2 to 24 days.

The PCR tests from the conjunctival sac swabs were positive in 33 patients (11%), negative in 259 patients (86%), and ten patients (3%) were with the unclear result. In the group of 33 positive patients were 17 males with a mean age of 74.6 ± 13.59 years and 16 females with a mean age of 70.63 ± 14.17 years.

The cycle threshold (C_T) values differed significantly between conjunctival sac swabs from the nasopharynx and the conjunctiva. Medians of the values were 25.1 (14.1, 32.1) and 31.5 (22.6, 36.6) (P <  0.001), respectively.

Conclusion

This study affirmed that in COVID-19 patients the SARS-CoV-2 was detectable with PCR test in conjunctival sac swab, but the positivity rate was only about one to ten cases (11%).

Access to eye care during the COVID-19 pandemic, India

OBJECTIVE

To study the impact of the coronavirus disease 2019 (COVID-19) pandemic on outpatient visits to eye care facilities in south India.

METHODS

We used data on 7.69 million outpatient visits to primary (i.e. vision centres), secondary and tertiary Aravind Eye Care System's centres between January 2019 and June 2021. We compared outpatient numbers and outpatients' age and sex between the pandemic period and the pre-pandemic period in 2019 for all centres, whereas vision and ophthalmic assessments were compared for vision centres only.

FINDINGS

During the first wave, the number of outpatient visits at tertiary, secondary and vison centres was 39% (647 968/1 656 296), 60% (170 934/283 176) and 73% (180 502/246 282) respectively, of 2019 levels. During the second wave, outpatient visits at tertiary, secondary and vision centres were 54% (385 092/710 949), 73% (88 383/121 739) and 79% (121 993/154 007), respectively, of 2019 levels. The proportion of outpatients who were female or younger than 20 years or older than 60 years was significantly lower during the first and second waves than in 2019 (P < 0.0001 for all). The proportion of outpatients whose worse eye vision was poorer than 5/60 or who required referral was significantly higher (P < 0.0001 for both).

CONCLUSION

Restrictive measurements led to declines in outpatient visits, however the decline was less at secondary and vision centres than at tertiary centres. Easy access to specialized ophthalmic care via telemedicine and the relative proximity of these centres to communities helped reduce barriers to access.

An Ophthalmologist's Insight Into The Viral Pandemics

In recent past, major pandemics and epidemics have occurred due to the emergence and resurgence of the novel strains of viruses like Influenza [HINI-A "Spanish Flu", H1N1-Novel A "Swine flu"], Corona [Middle East Respiratory Syndrome (MERS), Severe acute respiratory syndrome (SARS-CoV-1, SARS-CoV-2)] and Ebola virus [Ebola virus disease]. These infectious diseases may have several ocular manifestations and rarely might be the presenting symptom of the underlying disease. The eyes can act as a portal of entry and/or route of viral transmission for these pathogens. Therefore, an ophthalmologist/optometrist needs to act with ample preparedness and responsibility. Establishing a standard of care in ophthalmic practice by modifying the conventional examination techniques and adopting tele-ophthalmology model to triage the patients can control the community spread of the disease. This article aims to elucidate the ocular manifestations in these pandemics and measures that should be adopted in ophthalmic practice to prevent the disease transmission.

Anterior Segment Surgery Performed During the COVID-19 Pandemic

OBJECTIVES

This study evaluated anterior segment surgeries performed during the coronavirus 2019 (COVID-19) pandemic. Prevention of virus transmission is a critical consideration for surgeons, and includes assessment of etiology, the referral region, demographic characteristics, and the surgery to be performed.

METHODS

The data of 144 patients who underwent anterior segment surgery between March 19, 2020 and June 1, 2020 were retrospectively reviewed. The patient demographic data and details of ophthalmological examination findings, the region patients were referred from, and the type of surgery performed were recorded and analyzed.

RESULTS

A total of 144 patients, 49 women (34%) and 95 men (66%), were included in this study. The mean age of the patients was 31.30±25.88 years (range: 1-86 years). The presenting complaint was in the right eye in 43.7% of the cases, in the left eye in 52.8%, and in both eyes in 3.5% of the cases. While 94.4% of the applications were from Istanbul, the remaining 5.6% were from outside the province. Though 43.7% of the cases were patients seen previously at the study hospital in Istanbul, 56.3% presented for the first time. This hospital was the first referral center in only 39.6% of the cases. Evaluation of etiology indicated that corneal perforation (18.1%) was the most common, followed by keratitis (13.2%). The most common surgical intervention applied was amnion membrane transplantation (19.4%), followed by perforation repair (16.7%).

CONCLUSION

Ophthalmological surgeries continue to be performed during the ongoing COVID-19 pandemic, however, special algorithms must be used to reduce the risk of COVID-19 transmission and to ensure continuity of healthcare for ophthalmology patients.

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.

Preoperative COVID-19 Testing for Elective Ophthalmological Procedure in a Tertiary Health Care Centre: Our Experience During the Pandemic

Background

To study the prevalence of coronavirus infection among asymptomatic patients requiring eye surgery and the role of screening in prevention of spread of infection among the healthcare workers.

Design

The prospective observational study was conducted in the Ophthalmology department of a tertiary care center in Delhi from September 2020 to December 2020.

Setting

Patients requiring elective ophthalmological procedures in a tertiary care hospital were screened for coronavirus using the RT-PCR method. Testing methods and results were documented.

Results

Among the 218 asymptomatic patients posted for elective surgery in that period, 16 (7.3%) were found to be positive for COVID-19. Those who tested positive were advised home isolation and surgery was postponed for the next 14 days. No complications were reported in these patients. One health-care worker also tested positive for COVID-19 during our study period.

Conclusion

In our study, 1 out of 14 asymptomatic patients were found to be carriers for the novel virus. Asymptomatic COVID-infected patients may lead to transmission of the virus inside the hospital among the visiting patients and hospital staff while they have no adverse effect on the surgery and its outcome.

Assessment of health equity consideration in masking/PPE policies to contain COVID-19 using PROGRESS-plus framework: a systematic review

INTRODUCTION

There is increasing evidence that COVID-19 has unmasked the true magnitude of health inequity worldwide. Policies and guidance for containing the infection and reducing the COVID-19 related deaths have proven to be effective, however the extent to which health inequity factors were considered in these policies is rather unknown. The aim of this study is to measure the extent to which COVID-19 related policies reflect equity considerations by focusing on the global policy landscape around wearing masks and personal protection equipment (PPE).

METHODS

A systematic search for published documents on COVID-19 and masks/PPE was conducted across six databases: PubMed, EMBASE, CINAHL, ERIC, ASSIA and Psycinfo. Reviews, policy documents, briefs related to COVID-19 and masks/PPE were included in the review. To assess the extent of incorporation of equity in the policy documents, a guidance framework known as 'PROGRESS-Plus': Place of residence, Race/ethnicity, Occupation, Gender/sex, Religion, Education, Socioeconomic status, Social capital, Plus (age, disability etc.) was utilized.

RESULTS

This review included 212 policy documents. Out of 212 policy documents, 190 policy documents (89.62%) included at least one PROGRESS-plus component. Most of the policy documents (n = 163, 85.79%) focused on "occupation" component of the PROGRESS-plus followed by personal characteristics associated with discrimination (n = 4;2.11%), place of residence (n = 2;1.05%) and education (n = 1;0.53%). Subgroup analysis revealed that most of the policy documents (n = 176, 83.01%) were focused on "workers" such as healthcare workers, mortuary workers, school workers, transportation workers, essential workers etc. Of the remaining policy documents, most were targeted towards whole population (n = 30; 14.15%). Contrary to "worker focused" policy documents, most of the 'whole population focused' policy documents didn't have a PROGRESS-plus equity component rendering them equity limiting for the society.

CONCLUSION

Our review highlights even if policies considered health inequity during the design/implementation, this consideration was often one dimensional in nature. In addition, population wide policies should be carefully designed and implemented after identifying relevant equity related barriers in order to produce better outcomes for the whole society.

Online survey on practice patterns in the treatment of corneal ulcer during COVID-19 pandemic

Purpose:

To evaluate practice patterns in the treatment of corneal ulcer by ophthalmologists during COVID-19 pandemic in the Indian subcontinent.

Methods:

This was an online questionnaire-based survey circulated via google form to reach ophthalmologists practising cornea as a subspeciality between January 4, 2021 and February 3, 2021. The survey comprised of 21 questions to evaluate the prevailing practice patterns in corneal ulcer management during pandemic.

Results:

In total, 39.3% of government ophthalmology clinics and 41.5% of private ophthalmology clinics reported an average delay of 2 weeks in presenting to the hospital after the onset of symptoms. Totally, 60.5% of participants reported that the clinical outcomes of infectious keratitis cases during the COVID-19 pandemic were worse than before. In total, 61.3 and 41.1% of ophthalmologists in private and government sectors, respectively, were routinely performing corneal scrapings for corneal ulcer patients. The procedures were performed with adequate protective measures. In total, 68.5% participants mentioned decreased availability of donor cornea during the pandemic, and 44.4% reported compromised cornea practice due to the limited availability of essentials (tissue adhesives, BCLs, medications, etc.). A statistically significant difference of effect of pandemic on cost of services was noted between government and private hospitals. In total, 51% participants from private hospitals reported hike in outpatient department services and surgical charges, and 78.6% from government hospitals mentioned no hike in the charges (P value <0.001).

Conclusion:

This study provides an overview on modified strategies in corneal ulcer management during pandemic without compromising patient safety and quality care.

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.

Publication trend of COVID-19 and non-COVID-19 articles in the Indian Journal of Ophthalmology during the pandemic

Purpose

To analyze the trend of COVID-19-related and non-COVID-19-related articles published in the Indian Journal of Ophthalmology (IJO) during the COVID-19 pandemic.

Methods

A retrospective analysis of all COVID-19 and non-COVID-19-related articles published in all the issues of IJO from January 2020 to March 2021 was performed. The data were obtained from the official website of IJO, Editor IJO monthly email, and PubMed. The monthly data were analyzed and a comparative analysis was done. The articles were segregated as Original, Review, Case Report/Series, Letter to the Editor/Commentary, Guest Editorial, Research methodology, Point-Counterpoint, Consensus Criteria, Ophthalmic Images, Photo Essay, Surgical Techniques, and AIOS Meeting Papers.

Results

Out of 1343 articles published in IJO during the pandemic, 182 (13.55%) were COVID-19-related and 1161 (86.45%) were non-COVID-19-related articles. Among COVID-19 articles (182), majority were letter to the editors 66 (36.26%), followed by original articles 39 (21.42%), commentaries 24 (13.18%), editorials 18 (9.89%), and preferred practices 13 (7.14%). The least were case reports five (2.74%), current ophthalmology and innovation three (1.64%) each, and one (0.54%) each of consensus criteria, images, and photo assays.

The lockdown issue with 223 articles, postlockdown phase 1 had 267, postlockdown phase 2 had 321, and postlockdown phase 3 with 316 (1127 articles) articles in IJO showed a rising trend in a number of published articles compared with the prelockdown issues (216 articles).

Conclusion

The quality and quantity of articles published in IJO increased and improved significantly. The results were seen with progressive improvement in citations and impact factors of the journal.

Pediatric cataract surgery practices in the COVID-19 era: Perspectives of a tertiary care institute in Northern India

PURPOSE

To discuss the impact of COVID-19 pandemic on the pediatric cataract surgery services in a tertiary care institute in India, as well as the protocol followed for these surgeries.

METHODS

COVID-19 has hampered outpatient and elective services and surgeries throughout the world. During the national lockdown imposed in March in India, outpatient services were suspended in our institute, leading to a tremendous backlog of pediatric patients with cataract. Since the delay in surgery in pediatric cataract can cause amblyopia, our institute had resumed pediatric cataract surgeries in June 2020 at the time of Unlock-1 in the country.

RESULTS

We have discussed the percentage of reduction in pediatric cataract surgeries in 2020 during the Unlock 1, 2, 3, and 4, as compared to the number of surgeries done by the pediatric ophthalmology unit in the same months last year. We had introduced triage and telemedicine in our department. We have discussed the preoperative, intraoperative, and postoperative protocol followed in our institute for children with pediatric cataract, and also the measures which can be taken for the safety of patients and staff.

CONCLUSION

It is essential to ensure COVID-19 protocol, i.e., wearing a mask, social distancing, and frequent hand hygiene, among the patients and health care personnel. Redesigning pediatric cataract surgery practices is essential to ensure the safety of the health care workers and the patients.

Point-of-care rapid antigen testing for COVID-19 at a tertiary eye care facility: Role in commencement of elective surgeries, contact tracing and implementation of back-to-work policy

PURPOSE

The aim of this study was to report the use and the impact of a point-of-care rapid antigen test (PoC-RAT) at a tertiary eye care facility in facilitating commencement of elective surgeries, contact tracing of exposed health care professionals (HCPs) and ancillary hospital staff, and implementation of back-to-work (BTW) policy for them.

METHODS

Retrospective analysis of subjects undergoing PoC-RAT for COVID-19 infection at a tertiary level dedicated eye care facility. Decision making with regard to commencement of elective surgeries post COVID-19 related discontinuation of services, contact tracing of HCPs and ancillary hospital staff exposed to known COVID-19 cases and implementation of back-to-work policy for all staff based upon the results of PoC-RAT were studied.

RESULTS

A total of 311 subjects (224 patients and 87 hospital staff) were tested. Overall positivity rate was around 7%. Asymptomatic patients who were screened preoperatively had a lower positivity rate at around 3% compared to the staff (who were either known contacts or were symptomatic) at around 17%. Contact tracing found three-quarters of the staff at low risk and only one quarter at medium or high risk. Among patients, 97% of those followed up for at least 2 weeks after the test remained healthy. For staff, this was around 65%.

CONCLUSION

Based on our preliminary results, we suggest that PoC-RAT may be considered routinely for indication-based preoperative screening of asymptomatic patients, and for on-campus screening, contact tracing and implementation of BTW policies for HCPs and ancillary hospital staff at a tertiary level eye care facility.

Impact of COVID-19 on Indian optometrists: A student, educator, and practitioner's perspective

PURPOSE

The optometry profession has experienced massive changes amid lockdown in COVID 19 pandemic. This study gauges the impact of COVID-19 on optometry education and practices in India.

METHODS

The impact of COVID-19 among key stakeholders of Indian optometry that included educators, students, and practitioners was surveyed. The content validity of the survey tool was achieved through a focused group discussion with experts.

RESULTS

Of the 1408 responses, 118 were educators, 845 were students and 445 were practitioners. Post COVID-19 lock-down, a high percentage of students (96%) and educators (94%) were now using online mode of education to learn and teach. The blended learning methods were reported to be used by 81% of educators. Practical skills were the most difficult to teach by educators and to learn by students. Almost a third of the students were concerned about their internships and job opportunities amid the pandemic. Practitioners felt confident in performing routine eye examinations with personal protective equipment (PPE). Telemedicine was found to be adopted by 55% of the private practitioners and 49% of the eye hospitals.

CONCLUSION

The COVID-19 pandemic has provided an opportunity to reform Indian optometry education through blended learning methods. Optometry practices changed and adapted instantly to the new hygiene norms that have raised the standard of care provided to patients. Telemedicine emerged as a mode of providing care by optometrists. Overall, all key stakeholders of optometry in India were found to have adapted well to the sudden changes due to COVID 19 pandemic.

Chemical disinfectants in ophthalmic practice

The instrumentation used in ophthalmic clinics can be a source of epidemics in health care set up. Contact tonometry with Schiotz or Applanation tonometer is associated with nosocomial epidemic keratoconjunctivitis outbreaks. Recently identified SARS-CoV-2 (COVID -19) spreads mainly via the respiratory route and fomites and can transmit through other body fluids, including tear film. Various ophthalmic instruments can become a common source of spreading cross infections. Chemical disinfection is one of the most common methods employed to decontaminate instruments and environmental surfaces and prevent transmission of infectious pathogens to patients through medical and surgical instruments. Various chemical disinfectants are available with a varied spectrum to work on a different group of organisms. In this article, we briefly cover commonly used chemical disinfectants in ophthalmic practice like Alcohol (Ethyl Alcohol, Isopropyl Alcohol), Chlorine-based solution (mainly Sodium Hypochlorite), Glutaraldehyde, Hydrogen Peroxide, Formaldehyde, Iodophors, and Quaternary Ammonium Compounds

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.

Propensity of aerosol and droplet creation during oculoplastic procedures: A risk assessment with high-speed imaging amidst COVID-19 pandemic

Purpose

The study uses principles of liquid and gas mechanics to verify and quantify the generation of aerosols in oculoplastic procedures, namely surgery using a scalpel, electrosurgical device, and a mechanized drill.

Methods

Surgical techniques were performed ex vivo using the electrosurgical device, scalpel, and mechanized drill on the muscle and bone of commercially available chicken. The liquid and gas dynamics were observed using a high-speed high-resolution Photron SA5 camera (0.125 to 8 ms temporal resolution, 0.016 to 0.054 mm/pixel spatial resolution) and stroboscopic lighting (Veritas 120 E LED Constellation). The analysis was performed using in-house algorithms and ImageJ software.

Results

The use of a mechanized drill at 35000 rpm and a 3 mm fluted burr generated aerosol with particle size 50 to 550 microns with a spread of 1.8 m radius. Surgical smoke was generated by an electrosurgical device in both cutting and coagulation modes. Dispersion of the smoke could be controlled significantly by the use of suction, mean smoke spread ratio being 0.065 without suction and 0.002 with use of suction within 2 cm.

Conclusion

The quantification of the aerosol generation will help surgeons take practical decisions in their surgical techniques in the pandemic era.

Profile of patients receiving intravitreal anti-vascular endothelial growth factor injections during COVID-19-related lockdown

Purpose:

The aim of this study was to analyze the impact on vision due to delay in presentation of patients requiring intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections, consequent to COVID-19-related travel restrictions.

Methods:

Data were collected retrospectively of patients who received anti-VEGF injections during four months of the COVID-19 pandemic. Visual acuities, indication for treatment were noted along with basic demographic characteristics.

Results:

Data were analyzed for 303 eyes of 263 patients. The indication for treatment was age-related macular degeneration (AMD) in 60 eyes (19.8%), while 162 eyes (53.5%) had Diabetic Macular Edema, 71 eyes (23.4%) had Retinal Vein Occlusion and 10 eyes (3.3%) had other diagnosis. The visual acuity in the treatment naïve eyes (Group A, n = 168) was significantly worse (P < 0.001) than those who presented for retreatment (Group B, n = 135). In Group B, there was a significant decline in vision for the entire cohort (P = 0.009) and those with AMD (P = 0.036). Those in Group B presented at a mean interval of 19.1 ± 10.6 (range, 4–64) weeks for retreatment.

Conclusion:

The COVID-19 pandemic has led to a delay in patients receiving anti-VEGF injections. The visual acuity is worse in both treatment naïve as well as those requiring retreatment. This could have long-term impact on vision of patients requiring this vision preserving treatment.

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.

Glaucoma care during the coronavirus disease 2019 pandemic

PURPOSE OF REVIEW

The current article reviews the impact of the coronavirus disease 2019 (COVID-19) pandemic on the delivery of ophthalmic, and specifically, glaucoma care.

RECENT FINDINGS

Literature from the review period includes case series demonstrating the presence of severe acute respiratory syndrome coronavirus 2 RNA in the conjunctival secretions of patients with laboratory-confirmed COVID-19. The global ophthalmology community published reports outlining the enhanced infection control measures undertaken by different institutions around the world to mitigate transmission of the novel coronavirus. Telemedicine has been increasingly implemented in glaucoma practices to reduce in-office patient volume. New data regarding the efficacy and feasibility of tools for home monitoring of intraocular pressure, virtual visual field testing, and remote disc photography are reviewed.

SUMMARY

COVID-19 has posed a global public health threat due to the severity of its contagion and associated morbidity and mortality. Glaucoma specialists have responded to the pandemic with innovative modifications to reduce viral transmission and optimize patient and staff safety in the office and operating room. The role of teleglaucoma has expanded and will continue to evolve as remote diagnostic devices undergo further refinement and validation.

Virus containment box for retinopathy of prematurity screening and laser

Purpose:

Health care workers are susceptible to contracting infection with COVID-19 by aerosol transmission. This is a risk while examining and/or treating an un-sedated neonate in retinopathy of prematurity (ROP) screening and treatment. But screening for neonates for ROP and treating with laser, when required, should not be delayed to avoid the blindness. We describe a cost-effective method of containing aerosols generated during such a procedure in an un-sedated baby.

Methods:

An acrylic transparent containment box was prepared to accommodate an average-sized infant. The box had four walls and a roof. The floor was open to place the container box over the baby. The walls have two types of openings, large ones to allow passage of hands to examine the baby, small ones to enable passage of oxygen tubing when required. A simulation was created to examine the impact of aerosol spray on examining healthcare personnel.

Results:

The cost of the acrylic box was negligible. It could be assembled locally with available acrylic sheets and craftsmen. It was not difficult to examine the baby inside the box, and the simulation demonstrated that it protected the health personnel from the aerosol contamination.

Conclusion:

The described method is likely to increase healthcare personnel's confidence not to delay or deny ROP screening and laser treatment and save the babies from blindness.

Resurgence of combined intravenous Ketamine and regional anesthesia in pediatric ocular surgery in COVID-19 pandemic

Purpose:

The current pandemic of COVID-19 has made airway procedures like intubation and extubation, potential sources of virus transmission among health care workers. The aim of this work was to study the safety profile of combined ketamine and regional anesthesia in pediatric ocular surgeries during the COVID-19 pandemic.

Methods:

This prospective study included pediatric patients undergoing ocular surgery under general anesthesia from April to October 2020. Children were premedicated with oral midazolam (0.25–0.50 mg/kg) or intramuscular ketamine (7-10 mg/kg), ondensetron (0.1 mg/kg) and atropine (0.02 mg/kg). Anesthesia was achieved with intravenous ketamine (4–5 mg/kg) and local anesthesia (peribulbar block or local infiltration). The patient's vital signs were monitored. Serious complications and postoperative adverse reactions related to anesthesia were documented.

Results:

A total of 55 children (62 eyes) were operated. Lid tear was the most common surgical procedure performed [n = 18 (32.7%)]. Dose of ketamine needed ranged from 30 to 120 mg (66.67 ± 30.45). No intubation or resuscitation was needed. Four children complained of nausea and two needed an additional dose of intravenous ondansetron due to vomiting in the post-operative period. Incidence of postoperative nausea and vomiting was not affected by age, duration of surgery or dose of ketamine used (P > 0.05). There was no correlation between increase in pulse and dose of ketamine.

Conclusion:

Combined ketamine and regional anesthesia is a safe and effective alternative to administer anesthesia in a child during ocular surgeries.

A Year of Living Dangerously: Challenges and Recommendations for Safely Performing Ophthalmic Surgery During the COVID-19 Pandemic, from Start to Finish

The COVID-19 pandemic has forced all nations to take an active role in infection control incorporating recommendations and measures to control viral dissemination. The epidemiological impact is very diverse and dynamic, even within the same region. Scientific knowledge regarding SARS-CoV-2 continues to improve every day with protocols needing to be updated and adjusted on a regular basis. Ophthalmology is a medical specialty identified to be at high risk for several reasons: it has very close doctor-patient contact, the virus has been detected in tears, and the ocular surface serves as a gateway to developing the infection. We have reviewed the current information on SARS-CoV-2 in the ophthalmologic field and provide up-to-date recommendations to help create protocols that can adapt to the dynamic situation of ophthalmologic institutions, patient cases, economic situations and access to diagnostic tests. This paper outlines the main recommendations regarding the initial consultation and outpatient clinics, measures to apply in the operating room (OR), and suggestions for post-surgical controls. Triage, according to the patient’s conditions and eye pathology, reduction of the time the patient is at the institution, social distancing, correct use of personal protective equipment (PPE), barrier methods, hygiene, as well as other recommendations mentioned in this document, will allow physicians to take care of the visual health of the patients while reducing the impact of the COVID-19 pandemic.

Response of L V Prasad Eye Institute to COVID-19 outbreak in India: experience at its tertiary eye care centre and adoption to its Eye Health Pyramid

AIM

To summarize the experience of response to COVID-19 outbreak at a tertiary eye care institute and its network of health facilities in India.

METHODS

Our responses are based on the principles of social distancing, hand hygiene, respiratory etiquettes, surface disinfection protocol, and rational use of appropriate personal protective equipment (PPE). We describe our response in terms of administrative controls, clinical protocols, staff protection, environmental controls, and social distancing measures. We also discuss our communication strategies and monitoring systems, to ensure compliance to protocols.

RESULTS

Administrative control is mainly related to formation of task force and its functions. Clinical protocols are related to patient triaging methods and clinical examination guidelines in Outpatient, Inpatient and Operating Room. Staff protection is focused on training staff on the protocols to be followed in hospital as well as at home, and use of PPE. Environmental protocol is focused on cleaning and disinfectant methods to be used in the hospital. In addition, there are systems for communication as well as monitoring compliance to protocols.

CONCLUSION

We hope that these protocols and our experience would help the ophthalmic community globally and serve as a guide to protect ophthalmologists and ophthalmic care personnel, and their patients across the world.

Rethinking Elective Cataract Surgery Diagnostics, Assessments, and Tools after the COVID-19 Pandemic Experience and Beyond: Insights from the EUROCOVCAT Group

The progressive deterioration of the visual function in patients on waiting lists for cataract surgery has a negative impact on their quality of life, especially in the elderly population. Patient waiting times for cataract surgeries in many healthcare settings have increased recently due to the prolonged stop or slowdown of elective cataract surgery as a result of coronavirus disease 19 (COVID-19). The aim of this review is to highlight the impact of such a "de-prioritization" of cataract surgery and to summarize some critical issues and useful hints on how to reorganize cataract pathways, with a special focus on perioperative diagnostic tools during the recovery phase and beyond. The experiences of a group of surgeons originating from nine different countries, named the European COVID-19 Cataract Group (EUROCOVCAT), have been combined with the literature and recommendations from scientific ophthalmic societies and healthcare institutions. Key considerations for elective cataract surgery should include the reduction of the number of unnecessary visits and examinations, adoption of precautionary measures, and implementation of telemedicine instruments. New strategies should be adopted to provide an adequate level of assistance and to guarantee safety conditions. Flexibility will be the watchword and regular updates would be necessary following scientific insights and the development of the pandemic.

Quantitative High-speed Assessment of Droplet and Aerosol From an Eye After Impact With an Air-puff Amid COVID-19 Scenario

PURPOSE

To quantify aerosol and droplets generated during noncontact tonometry (NCT) and assess the spread distance of the same.

METHODOLOGY

This was an experimental study on healthy human volunteers (n=8 eyes). In an experimental setup, NCT was performed on eyes (n=8) of human volunteers under normal settings, with a single and 2 drops of lubricant. High-speed shadowgraphy, frontal lighting technique, and fluorescein analysis were used to detect the possible generation of any droplets and aerosols. Mathematical computation of the spread of the droplets was then performed.

RESULTS

In a natural setting, there was no droplet or aerosol production. Minimal splatter along with droplet ejection was observed when 1 drop of lubricant was used before NCT. When 2 drops of lubricant were instilled, a significant amount of fluid ejection in the form of a sheet that broke up into multiple droplets was observed. Some of these droplets traversed back to the tonometer. Droplets ranging from 100 to 500 µm in diameter were measured.

CONCLUSIONS

There was no droplet generation during NCT performed in a natural setting. However, NCT should be avoided in conditions with high-tear volume (natural or artificial) as it would lead to droplet spread and tactile contamination.

"Depression, Anxiety and Stress" in a Cohort of Registered Practicing Ophthalmic Surgeons, Post Lockdown during COVID-19 Pandemic in India

Purpose: To assess the magnitude of mental health problems among ophthalmologists in India post lockdown during COVID pandemic.Method: Cross-sectional survey conducted online on registered practising ophthalmologists of India, post lockdown at the start of elective surgeries (20^th to 25^th May, 2020). The degree of symptoms of depression, anxiety and stress was assessed by DASS -21 questionnaire. DASS -Subscales: DASS- D (depression), DASS- A (anxiety) and DASS-S (stress) and grading of severity (mild, moderate, severe) were analysed.Results: A total of 144 ophthalmologists aged 29-72 years responded to online survey. Of all participants, 94 (64.2%) of ophthalmologists suffered from mental health problems. Seventy six (52.7%) ophthalmologists had depression and anxiety whereas 20 (14%) reported stress. Women ophthalmologists scored highest total DASS mean score and DASS-stress mean score (p = .04 and p = .03). Results of DASS-D and DASS-A showed female preponderance (men vs women 42.5% vs 61.5%, p = .02; 42.5% vs 60%, p = .04). Severity of symptoms revealed that ophthalmologists above 40 years of age with more than 10 years' experienced severe stress (p = .005). Comprehensive ophthalmologists presented with severe stress and ophthalmologists practicing speciality with severe anxiety. Pearson's correlation analysis showed positive correlation between total DASS-21 score with each of the three subscales scores (DASS D, r-0.88: p < .001; DASS-A, r = 0.96: p = <0.001; DASS-S, r = 0.95: p < .001).Conclusion: Screening by Dass-21 scale has brought noticeable transient mental health issue among ophthalmologist to the fore. Few with high risk may require professional mental care to alleviate it.
