Abstract
The COVID-19 pandemic has taken tragic proportions and has disrupted lives globally. In the wake of governmental lockdowns, ophthalmologists need practical and actionable guidelines based on advisories from national health departments on how to conduct their duties during nationwide lockdowns and after these are lifted. In this paper, we present a preferred practice pattern (PPP) based on consensus discussions between leading ophthalmologists and health care professionals in India including representatives from major governmental and private institutions as well as the All India Ophthalmological Society leadership. In this document, the expert panel clearly defines the range of activities for Indian ophthalmologists during the ongoing lockdown phase and precautions to be taken once the lockdown is lifted. Guidelines for triage, governmental guidelines for use of personal protective equipment from ophthalmologists' point of view, precautions to be taken in the OPD and operating room as well as care of various ophthalmic equipment have been described in detail. These guidelines will be applicable to all practice settings including tertiary institutions, corporate and group practices and individual eye clinics and should help Indian ophthalmologists in performing their professional responsibilities without being foci of disease transmission.Entities:

Subspecialty - wise triage of ophthalmic clinical situations**
| Specialty | Emergency - See immediately | Urgent - See as soon as possible | Routine - Reschedule >3 months or Teleophthalmology |
|---|---|---|---|
| New/Follow-up | • Any acute/severe vision loss | • Blepharitis | |
| • Mild/moderate dry eye | |||
| • Watery eye | |||
| • Most conjunctivitis (triage via teleophthalmology) | |||
| Surgery | • Elective cataract surgery, Nd: YAG capsulotomy | ||
| • Laser refractive surgery | |||
| New/Follow-up | • Cataract/Posterior capsule opacification | ||
| Surgery | • Cataract surgery for intractable high IOP (phacomorphic glaucoma, phacolytic glaucoma, angle-closure glaucoma), Cataract surgery for traumatic cataract with the ruptured anterior lens capsule | • Cataract surgery for cataract blindness when the patient is legally blind (i.e., combined effect of BCVA <6/60 in both eyes or field of vision constricted to 10 degrees or less of arc around central fixation in the better eye) | • Elective cataract surgery, Nd: YAG capsulotomy |
| New/Follow-up | • Microbial keratitis | • Minor trauma (e.g., abrasions, foreign bodies, recurrent corneal erosions) | • Blepharitis |
| Surgery | • Urgent tectonic keratoplasty (perforations) | • Keratoplasty for bullous keratopathy with a high risk of infection or pain | • Laser refractive surgery |
| New/Follow-up | • IOP >40 mm Hg | • After a change of glaucoma therapy where IOP is anticipated to change | • Stable glaucoma monitoring with no documented progression for 2 years |
| Surgery | • Acute uveitic glaucoma | • Lens extraction surgery to ameliorate angle closure disease when the risk of progression of angle-closure or glaucoma over the next 6 months is unacceptably high. This includes the at-risk fellow eye of eyes blinded by angle closure disease | • Elective cataract surgery in glaucoma patient not blinded by cataract |
| New/Follow-up | • Suspected or confirmed active CNV needing treatment | Macular edema requiring treatment | • Non-neovascular (dry) AMD |
| New/Follow-up | • Acute retinal detachment | • Acute full-thickness macular holes | • Epiretinal membranes |
| Surgery | • Surgery for the above, surgery for ROP and drainage in cases with appositional choroidal effusion, suprachoroidal hemorrhage, or flat anterior chamber | • Surgery for the above | • Surgery for the above |
| New/Follow-up | • Acute anterior uveitis, posterior uveitis, panuveitis | • Chronic/persistent anterior uveitis managed with topical therapy only, teleophthalmology recommended where possible | • Patients with an established history of recurrent, self-limiting episodes of acute anterior uveitis without sight-threatening complications (e.g., cystoid macular edema, steroid response) could be considered for teleophthalmology consult at the onset of a recurrence and for follow-up at 6-8 weeks, with clinical review if indicated |
| Surgery | • Vitreous biopsy and/or AC tap for infectious/inflammatory uveitis or malignant tumors | • Most uveitic cataracts | |
| New/Follow-up | • Suspected malignant ocular tumors (e.g., retinoblastoma, uveal melanoma, metastases, intraocular lymphoma, etc.) | • Fundus tumors/lesions causing macular exudation (choroidal haemangioma, Coats, retinal capillary haemangioblastoma) | • Stable choroidal naevi, CHRPE, iris cysts |
| Surgery | • Surgery for malignant tumors (including plaque brachytherapy for choroidal melanoma, enucleation, EUA and focal therapy, chemotherapy, etc) | Surgery for the above | |
| Alert: Due to the high risk of COVID 19 infection from the nasopharynx, avoid all nasal syringing, lacrimal surgery and nasal endoscopy. Treat thyroid eye disease medically first. If orbital decompression is still required, avoid medial wall/floor decompression which creates an entry into the paranasal sinuses. | |||
| New/Follow up | • Severe thyroid eye disease | • Progressive benign orbital tumors | • Orbit: all other, including TED (stable mild-moderate) |
| • Severe unilateral ptosis in an infant | |||
| Surgery | • Surgery for the above | • Surgery for the above | • Surgery for the above |
| New/Follow-up | • Most patients | ||
| New/Follow-up | • Sight or potential life (systemic) threatening conditions | • Patients having amblyopia treatment. Where possible, use teleophthalmology | • Case by case triage |
| Surgery | • Cataract surgery in under<4 month age or where causing amblyopia | ||
| New/Follow-up | • Triage of referrals on a case by case basis (accept suspected neurological strabismus) | • Triage of referrals on a case by case basis (except strabismus where amblyopia management is also required). Where possible, use teleophthalmology | • Most other non-acute strabismus cases |
| Surgery | • Acute trauma-related conditions requiring immediate surgery | • Most strabismus surgery and botulinum muscle injections | |
| New/Follow-up | • Patient by patient triage needed (except acute optic neuropathies, suspected SOL or raised intracranial pressure, neurological diplopia, acute pupillary signs) | • Where possible, use teleophthalmology | • Stable patients or patients where management will not change outcomes |
| Surgery | • Optic nerve sheath fenestration for severe visual loss in idiopathic intracranial hypertension, Temporal artery biopsy | ||
