ABSTRACT
PURPOSE: To evaluate the impact of an educational video in improving awareness of eye donation among non-medical healthcare workers at a tertiary health centre. METHODS: A socio-behavioural study on knowledge and attitude towards eye donation was conducted among 373 non-medical healthcare workers through a printed semi-structured questionnaire before and after viewing a bilingual educational video. The responses were evaluated and scored. RESULTS: Pre-intervention, only 5.4% of the participants had adequate knowledge, which improved significantly to 71.6% after watching the video (P < .001). Respondents with elementary school education showed the greatest change in knowledge. Pre-intervention, 72.4% were willing to donate their eyes, which significantly increased to 89.5% after watching the video. Pre-intervention, 66.22% showed a "highly favourable" attitude, which improved to 97.86% after watching the video. CONCLUSION: The 25 min video about eye donation and eye banking significantly changed the participants' knowledge, willingness, and attitude. Hence, media-based (video) awareness platforms may be valuable for improving the general public's knowledge and attitude towards eye donation. This may help in enhancing the eye donation rate in the long term.

SIGNIFICANCE: On comparing the Humphrey Field Analyzer (HFA) 24-2C Faster, which tests 10 additional points in the central field, with the 24-2 Swedish Interactive Thresholding Algorithm (SITA) Standard for detecting central field defects, we found that the HFA 24-2C Faster may be used for the initial field evaluation in glaucoma with the advantage of a shorter testing time. PURPOSE: This study aimed to compare the HFA 24-2C Faster with the 24-2 SITA Standard and 10-2 among patients with glaucoma for the number of defective central points, global indices, and testing time. METHODS: Sixty eyes of 60 patients with glaucoma and glaucomatous visual field defects on the 24-2 SITA Standard algorithm underwent the 24-2C Faster and 10-2 field tests. The number of central points detected, global indices, and reliability indices were compared between the 24-2C Faster and the 24-2 SITA Standard and 10-2 field tests. RESULTS: The 24-2C Faster, on average, detected 5.5 defective points more on the total deviation plot and 2 defective points more on the pattern deviation plot than the 24-2 SITA Standard in central 10°. The 10-2 algorithm detected 2.5 times more points on the total deviation plot than the 24-2C Faster. There was excellent consistency by an intraclass correlation coefficient of 0.95 for the mean deviation and 0.93 for the pattern standard deviation between the 24-2C Faster and the 24-2 SITA Standard. There was good consistency by an intraclass correlation coefficient of 0.80 for both mean deviation and pattern standard deviation between the 24-2C Faster and the 10-2. The testing time was significantly lower with the 24-2C Faster compared with the 24-2 SITA Standard and 10-2 test. CONCLUSIONS: Our study demonstrates that the HFA 24-2C Faster may be used for the initial evaluation of the visual field in glaucoma with the added advantage of a shorter testing time compared with the 24-2 SITA Standard program.

PURPOSE: To compare visual field test results of Glaufield Lite AP901 CTS 133 (Appasamy Associates, Mannadipet Commune, Thirubhuvanai, Puducherry, India, hereafter Glaufield Lite) with Humphrey Field Analyser (HFA, Carl Zeiss Meditec, Dublin, California, USA, hereafter HFA). METHODS: A pilot study at a tertiary eye centre involving 23 normal and 24 glaucoma patients who underwent two consecutive visual field tests on (i) HFA 24-2 SITA Fast and (ii) Glaufield Lite Quick Central program. RESULTS: The mean testing time on HFA was significantly shorter than Glaufield Lite (normals: HFA: 2.75 ± 0.49 min, Glaufield Lite: 6.85 ± 0.86 min, p < 0.001; glaucoma patients: HFA: 3.45 ± 1.08 min, Glaufield Lite: 6.95 ± 0.54 min, p < 0.001). Reliability criteria were similar, but false-positivity was lower with Glaufield Lite. Bland-Altman analysis showed poor agreement for mean deviation (MD), [~ 2.69 units less for HFA], and acceptable agreement for pattern standard deviation (PSD) [~ 0.426 units more for HFA] between the two devices. CONCLUSION: Both perimetric techniques showed reliable test results though test duration was longer with Glaufield Lite perimetry. The MD showed poor agreement, likely due to different scales and principles used for perimetry. The PSD showed acceptable agreement, making it valid for use in glaucoma, though a direct comparison of fields from the two devices is not possible. We recommend using the same perimetry device for follow-up evaluation.

We report an incident case of herpetic keratitis in a renal transplant recipient treated for acute renal allograft rejection. A lady in her forties, a renal transplant recipient on treatment for allograft rejection, was referred with mild ocular symptoms in the right eye for two days. On evaluation, she had mild conjunctival hyperemia and extensive herpetic epithelial keratitis involving the limbal and central corneas. The patient healed without sequelae from the antivirals and lubricants. Viral keratitis in immunosuppressed patients should be suspected, even in patients with mild symptoms, as early initiation of treatment can prevent rapid stromal involvement and scarring.
ABSTRACT
PURPOSE: To compare topical and peribulbar anesthesia in cataract surgery for hemodynamic changes, rate of complications and pain score in patients with cardiovascular disease. METHODS: A prospective comparative study at a tertiary care center in India. Patients >40 years old with treated/controlled hypertension and cardiovascular disease scheduled for cataract surgery under topical or peribulbar anesthesia were recruited. Heart rate, blood pressure, and ophthalmic and systemic complications were noted: preoperatively, immediately after block, intraoperatively, immediately postoperatively and 1 hour postoperatively. A visual analog scale was used to assess the pain score. RESULTS: A total of 150 patients (75 in each group) underwent cataract surgery. There was a significant rise in pulse rate and blood pressure after peribulbar injection and intraoperatively, which gradually reduced to baseline 1 hour after surgery in both groups (p < 0.001), with systolic blood pressure intraoperatively being significantly greater in the peribulbar group (155.49 ±18.14 mmHg vs. 147.95 ±17.71 mmHg, p = 0.01). The topical group had slightly lower visual analog scale scores (1.12 ± 0.99) than the peribulbar group (1.44 ± 0.90, p = 0.04). CONCLUSIONS: Cataract surgery appears safe in patients with adequately controlled cardiovascular disease, and topical anesthesia may be preferable due to noninvasiveness, adequate analgesia, and minimal effect on hemodynamic parameters. Therefore, hemodynamically stable patients of cardiovascular disease undergoing uncomplicated cataract surgery may be counselled for topical anesthesia.

PURPOSE: To compare blood pressure (BP), intraocular pressure (IOP), ophthalmic artery flow (OAF) velocity, retinal nerve fiber layer (RNFL) thickness, and visual fields in newly diagnosed hypertension (HT) patients (before treatment), chronic HT (on antihypertensive medications >5 years) and normotensives. METHODS: A prospective, cross-sectional study at a tertiary care centre in India. Three groups of 45 patients each: group 1 - early HT, group 2 - chronic HT, and Group 3 - normotensives, underwent evaluation of BP, IOP by Goldmann applanation tonometry (GAT), OAF velocity by transcranial doppler (TCD), RNFL analysis by spectral-domain optical coherence tomography (SD-OCT), and visual fields. RESULTS: The BP was highest in early HT > chronic HT > normotensives (p < 0.001). The IOP of early HT, chronic HT, and normotensives were 15.87 ± 2.19 mmHg, 13.47 ± 1.92 mmHg, and 15.67 ± SD 1.75 mmHg (p < 0.001). The OAF velocity [peak systolic velocity (PSV), end-diastolic velocity (EDV) in cm/sec] was lowest in chronic HT (30.80 ± 7.05, 8.58 ± 1.58) < early HT (35.47 ± 5.34, 10.02 ± 1.74) < normotensives (36.29 ± 4.43, 10.44 ± 2.29), (p < 0.001). The average RNFL thickness was significantly lower in chronic HT (p = 0.022). The PSV, EDV, and MFV showed significant correlation with IOP (r = 0.247, p = 0.004; r = 0.206, p = 0.016; r = 0.266, p = 0.002) and average RNFL thickness (r = 0.309, p= <0.001; r = 0.277, p = 0.001; r = 0.341, p < 0.001). CONCLUSIONS: Patients with chronic HT demonstrated the lowest retrobulbar flows, IOP and lower RNFL measurements. Lower ocular perfusion may be associated with lower IOP and may be a risk factor for end-organ damage (RNFL) independent of IOP.

Purpose: To assess the morphological changes in the anterior segment following laser peripheral iridotomy (LPI) in primary angle-closure disease (PACD) using Sirius Scheimpflug-Placido disk corneal topographer. Methods: This was a prospective observational study. A total of 52 eyes of 27 patients with PACD who underwent LPI were analyzed for iridocorneal angle (ICA), anterior chamber depth (ACD), anterior chamber volume (ACV), horizontal visible iris diameter (HVID), corneal volume (CV), central corneal thickness (CCT), and horizontal anterior chamber diameter (HACD) 1 week following LPI, using Sirius Scheimpflug-Placido disk corneal topographer. Data analysis was done using Statistical Package for the Social Sciences (SPSS) software version 19.0, and paired t-test was used to assess the statistical significance. Results: Laser peripheral iridotomy was performed in 43 eyes with primary angle-closure suspect (PACS), six eyes with primary angle closure (PAC), and three eyes with primary angle-closure glaucoma (PACG). The analysis of the data showed statistically significant changes in anterior segment parameters of ICA, ACD, and ACV. Post-laser increase in ICA from 34.13° ± 2.64° to 34.75° ± 2.84° (P < 0.041), mean ACD increase from 2.21 ± 0.25 to 2.35 ± 0.27 mm (P = 0.01), and mean ACV increase from 98.19 ± 12.13 to 104.15 ± 11.16 mm3 (P = 0.001) were noted. Conclusion: Significantly quantifiable short-term changes in the anterior chamber parameters of ICA, ACD, and AC volume were seen after LPI in patients with PACD on Sirius Scheimpflug-Placido disc corneal topographer.

PURPOSE: To report a case of spontaneous suprachoroidal haemorrhage in a haemophilia patient immediately following ChAdOx1 nCoV-19 vaccination. CASE PRESENTATION: A 60-year-old man with haemophilia developed painful vision loss in his left eye a day following the ChAdOx1 nCoV-19 vaccination due to acute angle-closure glaucoma from a massive suprachoroidal haemorrhage. He had an extremely deranged coagulation profile; activated partial thromboplastin time (APTT): 89 s, normal range 29-35 s After factor VIII transfusion, ocular hypotensive therapy and systemic/topical steroids, the suprachoroidal haemorrhage and glaucoma resolved, but the vision remained poor. CONCLUSION: Spontaneous suprachoroidal haemorrhage may be seen in haemophiliacs with deranged coagulation profiles. In our case, it followed ChAdOx1 nCoV-19 vaccination, and we recommend caution and checking the coagulation profile in such patients apriori.

Background: The use of human amniotic membrane transplantation is rapidly increasing for the management of various ocular surface disorders. Despite its numerous advantages, amniotic membrane is not widely available due to the lack of awareness among ophthalmologists regarding its preparation and preservation techniques. Purpose: To provide an instructional video demonstrating the technique of harvesting, preparation, preservation of human amniotic membrane, and its uses in the management of ocular surface diseases. Synopsis: The amniotic membrane is the innermost layer of the human placenta. Properties of the amniotic membrane, like the presence of various growth factors, anti-inflammatory and anti-angiogenic factors, and its low immunogenicity, contribute to its ability to promote epithelial growth and differentiation with the reduction in fibrosis during healing. To harvest amniotic membrane, informed consent is obtained from a patient undergoing an elective caesarian section, and the donor is screened to exclude the risk of infections. Under sterile precautions, the amniotic membrane is separated from the chorion and washed free of blood clots. With the epithelial surface up, the amniotic membrane is spread uniformly without folds or tears on individually sterilized 0.22 µm nitrocellulose filter papers of the required sizes. The prepared filter paper with the adherent amniotic membrane is placed in freshly prepared Dulbecco's Modified Eagle's Medium and stored at -80°C. The amniotic membrane can be used for surgical procedures like symblepharon release, pterygium or dermoid excision, perforated ulcers, nonhealing epithelial defects, etc. Highlights: Instructional videos demonstrating the preparation and preservation of amniotic membrane are very sparse. This video clearly explains how any ophthalmologist can learn to prepare and preserve the human amniotic membrane and gives a glimpse of its properties, advantages, and scope of use.

Purpose: This study was conducted to assess the intraocular pressure (IOP) control and postoperative complications following a non-valved glaucoma drainage device (GDD) surgery in refractory glaucoma. Methods: This was a prospective interventional study conducted on patients with glaucoma refractory to maximal medications or failed surgical treatment who underwent Aurolab aqueous drainage implant (AADI; Aurolabs, India) surgery. Primary outcome measures were IOP control, postoperative complications, and reduction in the number of antiglaucoma medications (AGM). Results: Thirty-four eyes were analyzed and the mean follow-up was 16.06 ± 5.63 months. The preoperative median (Q1, Q3) IOP was 31 mmHg (28, 36.5) which decreased to 12 mmHg (12, 14) at 6 months postoperatively. The median (Q1, Q3) number of AGMs decreased from 3 (3, 4) to 0 (0, 1). Significant complications like implant extrusion and tube exposure were noted in two eyes. The total success and failure rates at 6 months were 91.1% and 8.8%, respectively. Conclusion: AADI is effective in achieving target IOP and significantly reduces the use of AGMs with good safety in the short term. Long-term follow-up studies are needed to assess long-term IOP control and cost-effectiveness.

PURPOSE: To report a case of meta-herpetic ulcer that developed after intravitreal bevacizumab injection. METHODS: A 55-year-old man with type 2 diabetes mellitus and nephropathy received intravitreal injection of bevacizumab in his right eye for proliferative diabetic retinopathy with macular edema. RESULTS: Two days after the injection, the patient presented with severe pain, redness, and photophobia, and decreased visual acuity in the right eye. The cornea showed a paracentral epithelial erosion with heaped margins with subepithelial haze and punctate keratopathy, and high intraocular pressure. He initially responded to topical antiviral and antiglaucoma medications. However, it rapidly progressed to a geographic ulcer on initiation of mild steroid and became resistant to conventional medical management. His nephropathy precluded treatment with full dose of systemic antivirals and antiglaucoma drugs. Subsequently, it healed after a paramedian tarsorrhaphy was performed. CONCLUSION: Herpetic epithelial keratitis following intravitreal bevacizumab is a rare occurence. However, this case is the first report of progression to a meta-herpetic ulcer.

Purpose: To evaluate the effect of reducing blood pressure (BP) by atenolol and amlodipine on (1) intraocular pressure (IOP) and (2) ophthalmic artery blood flow (OAF) velocity in new hypertensives. Methods: A prospective, observational cohort study conducted at a tertiary care center in India after IRB approval. New hypertensives treated with atenolol 25 mg or amlodipine 5 mg were divided into 2 groups of 30 patients each. BP, IOP by Goldmann applanation tonometry and OAF velocity by transcranial doppler sonography was performed before medication and post medication on day 1, 7, and 30. Results: There was a significant decrease in IOP with both drugs; the effect was greater with atenolol. Atenolol: premedication IOP - 16.06 ± 2.13 mmHg and day 30-12.46 ± 1.94 (22.4%) [P < 0.001], amlodipine: premedication IOP-15.13 ± 2.55 mmHg and day 30- 13.06 ± 2.14 (13.68%) [P < 0.001]. A decrease of 0.5 mmHg in IOP with every 10 mmHg (95% CI: 0.121-0.826, P value = 0.01) decrease in systolic BP was noted after oral atenolol. The OAF peak systolic velocity and mean flow velocity were equally reduced with both drugs (P < 0.001). The end-diastolic velocity, reduced only with atenolol (P = 0.049) but returned to baseline with amlodipine at 1 month. Conclusions: BP reduction by atenolol and amlodipine led to decreases in IOP and OAF velocity, greater with atenolol. The IOP decrease was likely due to reduced blood flow. A slight decrease in the diastolic flow of the ophthalmic artery was noted with atenolol.

Cases of optic neuritis have been reported following the novel coronavirus disease 2019 (COVID-19), with most being unilateral and associated with demyelinating illness. We report a case of a 22-year-old woman who presented with sudden onset painless diminution of vision in both eyes six weeks following COVID-19 infection. She also had a history of left lower motor neuron (LMN) facial palsy immediately following COVID-19 disease that recovered fully on steroids. Ocular examination and ancillary and laboratory investigations pointed to bilateral atypical optic neuritis. The patient responded well to the standard optic neuritis treatment protocol. We diagnosed her as a case of left LMN facial palsy and parainfectious bilateral optic neuritis following COVID-19. Parainfectious bilateral optic neuritis and facial nerve palsy associated with COVID-19 can occur following COVID-19 disease. Ours is the first case to report the occurrence of both in a patient.
ABSTRACT
Purpose: To compare the anxiety levels related to visual field testing and optical coherence tomography (OCT) in patients with glaucoma. Methods: This prospective, comparative study was conducted on patients with glaucoma. The participants' anxiety traits were assessed using the State-Trait Anxiety Inventory [STAI]. Before visual field testing on Humphrey visual field analyzer (HVF) and retinal nerve fiber analysis on OCT, the participants completed Form Y1 to measure the current pretest level or 'State' anxiety [pretest anxiety]. Immediately after testing, participants were administered the Form Y1 questionnaire to assess the induced anxiety level during the testing [Intratest anxiety]. Results: A total of 228 patients were enrolled with 152 participants in the HVF group and 76 in the OCT group. The mean age of the participants in the HVF group was 57.2 ± 20.8 years and in the OCT group was 56.8 ± 20 years. There was no significant difference in trait and pretest anxiety between the HVF group and the OCT group (P = 0.971 and P = 0.716). Intratest test anxiety score was slightly higher in the HVF group (HVF: 42.13 ± 10.63, OCT: 40.71 ± 9.76; P = 0.33). The anxiety scores were higher when the experience of previous HVF tests was <2 and least when the number of tests exceeded five. Conclusion: Automated perimetry induces slightly more anxiety than OCT, which may affect test performance. The measured anxiety reduces as patients gain familiarity with the test with experience. This adds credence to the recommendation of more frequent visual field testing in newly diagnosed glaucoma patients.

Here, we report a case of acute endothelial graft rejection following coronavirus disease 2019 (COVID-19). A 57-year-old woman who underwent therapeutic penetrating keratoplasty for a perforated infectious corneal ulcer in her right eye developed severe acute respiratory syndrome coronavirus 2 infection, which required intensive care and treatment with steroids. Acute endothelial graft rejection was seen at three weeks postoperatively and managed with high-dose corticosteroids. Despite standard therapy, secondary graft failure was observed. Immune dysregulation associated with COVID-19 may be a significant cause of acute endothelial graft rejection among keratoplasty patients with COVID-19.
ABSTRACT
A 20-year-old male presented with acute lower limb oligoarthritis and enthesitis followed by acute onset redness, watering, pain and decreased vision in the right eye. He had recent history of diarrhoea with fever. Erythrocyte sedimentation rate and high-sensitivity C-reactive protein (hsCRP) were raised and human leukocyte antigen-B27 was positive. The best corrected visual acuity (BCVA) in the right eye was 20/120 and it showed a paracentral shallow corneal ulcer of size 3 × 4 mm with underlying dense stromal infiltrates and haze. Microbiological evaluation of corneal scrapings was reported as Staphylococcus hominis. The epithelium healed on topical antibiotics in one week, but there were persistent punctate erosions and pleomorphic anterior stromal infiltrates and haze. The residual keratitis healed completely on topical steroids in ten days, with BCVA improving to 20/20. A diagnosis of reactive arthritis with immune-mediated keratitis was made.

Prevention and early management of postburn cicatricial ectropion is the best strategy to avoid ocular complications, with poor visual prognosis in extreme cases. A 51-year-old man presented with diminution of vision and absolute inability to close both eyes, 3 months after thermal burn injuries to face, upper limbs, and trunk. His best corrected visual acuity (BCVA) was 1/60 in BE. He had bilateral extremely severe ectropion involving both upper and lower lids with complete inability to close the eyes. The ensuing exposure keratitis developed secondary infection by Methicillin-resistant Staphylococcus aureus (MRSA) in the right eye and multidrug-resistant Pseudomonas aeruginosa in the left eye. His extreme ectropion prevented infection healing, so its release and full-thickness skin grafting was done when partial resolution of infection was noted. After 3 months, he had moderate residual ectropion in BE; vascularized corneal scar in the inferior part of the right eye (BCVA:20/40) and adherent leucoma in left eye (BCVA:HM). Prioritizing ectropion surgery in our extreme case for infection control, facilitated corneal healing. Our case highlights the extreme consequences of not taking preventive measures or of managing incident ectropion following thermal injury to the face.

CASE REPORT: A 33-year-old lady with history of failed keratoplasty for decompensated cornea due to childhood trauma and secondary glaucoma, post glaucoma drainage implant, with pseudophakia in the right eye, developed bacterial keratitis following foreign body trauma to corneal graft. Corneal cultures yielded Burkholderia cenocepacia identified by matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF- MS, bioMerieux, France). She healed with topical antibiotics (moxifloxacin 0.5%) in 1 month. Ours is the first report of ocular Burkholderia cenocepacia infection, possibly an under reported, aerobic, organism.

PURPOSE: To report a case of acute hydrops in pellucid marginal corneal degeneration (PMCD) documented with anterior segment optical segment tomography and successfully treated with sulphur hexafluoride (SF6) intracameral injection. METHODS: A 47-year-old female patient presented with spontaneous onset of pain, redness and decreased vision in her left eye. Clinical evaluation revealed bilateral PMCD with evidence of acute hydrops in the left eye. Anterior segment Slit lamp Adapted Optical Coherence Tomography (SL-OCT) examination revealed intrastromal clefts with Descemet's membrane detachment in the left eye. She was managed with descemetopexy with 0.2ml injection of iso-expansile SF6 (18%) intracameral. RESULTS: The patient showed excellent early resolution of the stromal edema with reattachment of the Descemet's membrane. CONCLUSION: Prompt intervention in acute hydrops in PMCD cases helps in achieving early good visual results and prevents potentially serious complications such as perforation. Newer imaging modalities like SL-OCT helps in better visualisation and also in monitoring the response to treatment.
