Quick Response Code:

The COVID-19 pandemic has brought new challenges to the health care community. Many of thesuper-speciality practices are planning to re-open after the lockdown is lifted. However there is lotof apprehension in everyone’s mind about conforming practices that would safeguard the patients,ophthalmologists,healthcareworkersaswellas takingadequatecareof theequipment tominimize thedamage.Theaimofthisarticleistodeveloppreferredpracticepatterns,bydevelopingaconsensusamongstthe leadexperts, thatwouldhelp the institutesaswellas individualvitreo-retinaanduveitisexperts torestarttheirpracticeswithconfidence.Asthesituationremainsvolatile,wewouldliketomentionthatthesesuggestionsareevolvingandlikelytochangeasourunderstandingandexperiencegetsbetter.Further,thesuggestionsareforroutinepatientsasCOVID-19positivepatientsmaybemanagedindesignatedhospitalsasper localprotocols.Also thesesuggestionshave tobe implementedkeeping incompliancewith localrulesandregulations.

MethodsThis consensus was developed in continuation to theprevious publication by Sengupta et al.[1] The experts included the representatives ofVRSI,USI, iROP aswellas the retina chiefs frommajor centres in India.Thebasedocumentwas prepared by the allocation of sections todifferentexperts.Thepaperwasthencompiledandreviewedby theentire committee. In case therewasanydifferenceofopinion,amutualconsensuswasreachedbydiscussionamongstalltheexperts.Thefinalversionofthedocumentwasapprovedbyalltheauthors.

Finding in either eye with respect to zone Next follow up Comment

Immature retina in zone 3 and zone 2 anterior

3‑4 weeks or more If the PMA is less then 34 weeks/ < 1500 grams / sick and admitted infant, consider a closer follow‑up

ROP in Zone 3 and Zone 2 anterior 3‑4 weeks Spontaneously regressing ROP can be watched

ROP in Zone 2 Posterior 2 weeks Unless associated with treatment requiring features (see below)

ROP in Zone 1 Urgent / less than a week / treat Have a low threshold for treatment

Pre‑plus Consider early treatment or early follow‑up if pupil does not dilate well and media is not clear

Individualize for each case based on the tempo of disease and PMA

Pre‑plus With good pupillary dilatation and clear media and other low risk features

Can delay the next screening by an additional 1 week from the current guidelines

Table 3: Suggested ROP treatment guidelines by the Indian ROP Society during COVID-19 restrictions

Disease Comment

Type 1 ROP (ETROP) Treat as soon as you possible, preferably on the day that screening was done. Laser recommended

Any Zone 1 disease Consider treatment as soon as possible

Aggressive Posterior ROP / Hybrid ROP Treat as soon as possible. Laser if disease is amenable. Intravitreal injections can be used, but caution to be exercised since follow‑up may be a critical issue with travel restrictions for the family

“Less than Type 1 ROP” ROP Stage 2 with pre plus, ROP Stage 3 with no or early plus, high risk for APROP (but not yet full fledged), borderline Zone 1 disease / poor pupil dilatation, unclear media with pre‑plus

Given the difficulty to closely follow‑up consider treatment a ‘little earlier’ than classical Type 1 ROP

Stage 4A and 4B ROP Surgery must be performed as soon as treating ROP specialist feels it is required with adequate precautions taken while providing anesthesia (as per prescribed guidelines)

Stage 5 ROP Surgery is not urgent. Case‑to‑case based decision must be considered.

XI. Financial impact of new SOPsThere is a genuine fear of an increased expenditure thatwouldneed to be incurred for the new set of SOPs.Alsothe patient inflowmaydecrease due to fear of travelingor visiting thehospital, reducedfinancial resources in thepost-COVID-19economyanddecreasedhealthcarecapacity.Thiscanbeovercomebyincreasingthenumberofworkinghours to compensate for reducednumberofpatients seenper hour as per physician’s discretion, use of electronicmedicalrecordswithautomationwhereverpossible,onlineprepaymentportalandpre-registrationthroughonlineportalsorWhatsApp. The additional cost including sanitization,cleaning,providing 3-plymask topatient andPPE asperguidelinestoophthalmologistshasbeencalculatedtobeaboutRs88/patient.Thisincludesthecostofsanitizer:Rs.16/-(forpatientandattendant)+Rs.16/-forcleaninginstruments+Rs.16/-forcleaningfloorsandfomites+Rs.40/-cleaningpersonsalary.Thecostoffaceshields(variesfromRs75/-to200/-),andgoggles (100/- to 300/-) is a one time.The estimateofthe added cost canbedemystifiedand remove the fear inpeoples’minds.Thus,thepotentialextracostperpatientisanestimatedRs.88/-thatcanbeaddedtotheconsultationfeewithaddedprecautions.Thisisthenlikelytobecompletelyrevenueneutral.Theseestimatesarebeingprovidedasausefulyardstickandmaybevariable.

XII. Telemedicine and artificial intelligence (AI) for retinal disorder screening: Expanding role in post COVID-19 eraTelemedicine and artificial intelligence (AR) are two ofthe promising aspects of retina practice evolving in therecent yearswhich can provide safer alternatives overconventional examination in various case scenarios in thepostCOVID-19era.[23-29]

The utility of telemedicine has beenwell establishedfor screeningofDR,AMDandROP.[24-29] A wide variety of non-mydriaticfunduscamerashavebeeninusewithvaryingefficacyas faras imagequalityandfield is concerned.[23] In thecurrentscenario,hospitalscanpromotemoreofscreeningthrough telemedicine in order to avoid congestion andunnecessary hospital visits at tertiary eye care centers.Dependingon the available resources,hospitals can installsuitablefunduscamerasandarrangeforonlineconsultationwithretinaspecialists.Non-mydriaticultra-widefieldcameraslikeOptosorClaruscanhelpdetectawidevarietyofretinalpathologies,apartfromDR,ARMDandROP,althoughcostcanbeafactorfortheirinstallationbygeneralophthalmologists.[28] TertiaryeyecarecenterswhichlackROPscreeningthroughtelemedicinecanestablishthesamebasedonhighlysuccessfulexistingmodels.[24]

AlothasbeendoneintherecentpasttoexploretheutilityofAIinenhancingtheefficacyoftelemedicine.Conventionalmachinelearninghasfacilitatedrecognitionofabnormalitieslikemacularedema,exudates,cotton-wool,microaneurysms,neovascularizationonopticdisk, drusens andgeographic

atrophy.[27]Deep learning algorithmshavebroughthighersensitivity and specificity indiagnosing retinalpathologieswithhigheraccuracy.However,mostofthemneedvalidationinlargerpatientcohorts.[27]

XIII. Managing uveitis in post-COVID-19 eraGeneral ophthalmologists aswell asuveitis specialists arenowfacedwiththedilemmaabouttheusageofsteroidandimmunosuppressiveagents.Therearenopublishedguidelinessofarregardingthis.ThefollowingconsensusisbeingacceptedbytheInternationaluveitisstudygroup(IUSG),InternationalOcular Inflammation Society (IOIS) and Foster OcularInflammationSociety(FOIS)havejointlyreleasedanevolvingconsensusexperiencewithuveitis at the timeofCOVID-19infection(latestversionApril3rd2020).[31]

• Avoid starting high dose oral corticosteroids orimmunosuppressants in high risk patients defined as thefollowing:age≥70years,severechronic lungdisease(e.g., asthma, bronchiectasis, cystic fibrosis, chronicobstructivepulmonarydisease(COPD),etc.),severeheartdisease,CD4count<200,historyofdiabetes/hypertension/smoking/cardiovascularevent

2. TheCOVID-19pandemic is not a contraindication forthe initiation of immunosuppressants. Patients need tobe explained regarding the additional riskof secondaryinfectionsatthetimeofstartofthetherapyincludingthefollowingprecautions:
