Objective: Toxic anterior segment (TASS) is a rare acute sterile anterior segment inflammation that typically develops within 12 to 24 hours after an anterior segment surgery. The purpose of this case report is to alert surgeons to the possibility of this complication following any anterior segment surgery, including trabeculectomy, and to highlight the possible etiologies and measures to prevent it.Patient and method: A 58-year-old male glaucoma patient was initially managed medically for primary open angle glaucoma with antiglaucoma medications. There was rapidly progressive glaucomatous optic nerve damage in his left eye within the following year, despite the use of antiglaucoma medications, hence the need for trabeculectomy.Result: The post-operative condition of the patient’s eye was stormy with diffuse limbus-to-limbus corneal edema and profound Descemet’s membrane folds, among other features of TASS, with associated deteriorating visual acuity. Conclusion: Although there is no documented report of TASS following trabeculectomy with mitomycin C, surgeons should be alerted to this possibility. Preventive measures include extreme care to avoid errors while preparing and administering diluted solutions, especially medications that are administered into the intracameral space.

Phacoemulsification in hard cataracts is a challenge. The use of dispersive ophthalmic viscosurgical devices (OVDs) to protect the endothelium is a routine step in such scenarios. However, as OVD is transparent, it is difficult to spot within the anterior chamber. Therefore, surgeons may not be aware when the OVD coating of the endothelium disappears during surgery. Consequently, there may be too frequent OVD injections, resulting in a waste of resources. On the contrary, the surgeon may fail to inject OVD at an appropriate time, leading to greater endothelial damage. We propose a novel technique of using an air bubble as a guide that helps in identifying the time when OVD disappears from the anterior chamber, thereby suggesting the surgeon to reinject before proceeding further.

The high prevalence of mature, hypermature, and traumatic cataracts in developing countries, combined with the limited availability of surgical resources and skill by anterior segment surgeons to manage the resultant aphakia, leaves the patient needlessly blind. Relying on posterior segment surgeons, expensive surgical setup, and appropriate lenses for aphakia management limits the number of patients receiving a secondary intraocular lens (IOL). Utilizing the well-acknowledged flanging technique and the readily available polymethyl methacrylate (PMMA) lenses with dialing holes in their optic, a hammock can be created through the dialing holes using a 7-0 polypropylene suture on a straight needle. This 4-flanged scleral fixation through the dialing hole of an IOL makes scleral fixation of PMMA lens possible by even anterior segment surgeons without requiring any specialized equipment or scleral fixated lens with eyelet. This technique was successfully performed in a series of 103 cases with no incidence of IOL decentration. [ABSTRACT FROM AUTHOR]

Background: Automated perimetry in neurologically disabled patients is a challenge. We have devised a patient-friendly virtual reality perimeter, the C3 field analyzer (CFA). We aim to assess the utility of this as a visual field-testing device in neuro-ophthalmic patients for screening and monitoring. Methods: Neuro-ophthalmic patients and controls were selected to participate in the study between September and December 2018. They randomly underwent either the CFA or automated field analyzer (HFA) first followed by the other in an undilated state. The CFA results were compared with the HFA, and the correlation of the pattern of the field defect was assessed by an independent masked physician. Results: In total, 59 eyes of 33 neuro-ophthalmic patients (cases) and another 95 normal individuals (controls) were enrolled. CFA was found to have greater proportion of reliable fields (81.4%) than HFA (59.3%) (P = 0.009). There were less false negatives (P < 0.001) and more false positives in CFA (P < 0.001) among neuro-ophthalmic patients compared with controls. Among neuro-ophthalmology patients, the number of fixation losses was greater with CFA (P < 0.001), whereas false negatives were greater in HFA (P < 0.001). On assessing the pattern of the field defects, we found that there was almost 70% correlation of CFA with HFA. Moreover, in classical neurological fields such as hemianopia, the correlation was 87.5%. Conclusions: The CFA seems to correlate well with HFA in classic neurological fields such as hemianopias and may serve as an alternative in patients unable to perform a standard automated perimetry. Further developments are currently underway to incorporate threshold testing. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the visual and surgical outcomes of cataract surgery in patients with posterior polar cataract (PPC) and to evaluate the benefits of preoperative anterior segment optical coherence tomography (AS-OCT). Methods: This was a retrospective, single-center study. Case records of patients diagnosed with PPC who underwent cataract surgery either by phacoemulsification or manual small-incision cataract surgery (MSICS) from January to December 2019 were analyzed. Data collected include demographic details, preoperative best corrected visual acuity (BCVA), AS-OCT, type of cataract surgery, intraoperative and postoperative complications, and visual outcome at 1-month follow-up. Results: One hundred patients were included in the study. Preoperative posterior capsular defect was noted on AS-OCT in 14 patients (14%). Seventy-eight underwent phacoemulsification and 22 underwent MSICS. Intraoperatively, posterior capsular rupture (PCR) was seen in 13 patients (13%) and cortex drop was noted in one among them (1%). Out of 13 PCRs, 12 were found to have posterior capsular dehiscence preoperatively in AS-OCT. The sensitivity of AS-OCT for detecting posterior capsule dehiscence was 92.3% and specificity was 97.7%. The positive predictive value and negative predictive value were 85.7% and 98.8%, respectively. There was no significant difference in the incidence of PCR between phacoemulsification and MSICS (P = 0.475). The mean BCVA at 1 month was found to be better with phacoemulsification than MSICS (P = 0.004). Conclusion: Preoperative AS-OCT has excellent specificity and negative predictive value in identifying posterior capsular dehiscence. It thus helps to plan the surgery and counsel patients appropriately. Both phacoemulsification and MSICS provide good visual outcome with similar complication rates. [ABSTRACT FROM AUTHOR]

Purpose: To assess the differences in the pattern of presentation of glaucoma emergency conditions during the various phases of pandemic-related travel restrictions: first wave-related lockdown, unlock period, and the second wave-related lockdown. Methods: The number of new emergency glaucoma conditions, the various diagnoses, and the total number of all new glaucoma patients presenting to the glaucoma services at five tertiary eye care centers in south India from 24th March 2020 to 30th June 2021 were collected from the electronic medical records and were analyzed. The data were compared with the corresponding time period in the year 2019. Results: In total, 620 patients presented with an emergency glaucoma diagnosis during the first wave-related lockdown as against 1337 during the same period in 2019 (P < 0.0001). During the unlock period, 2659 such patients visited the hospital compared with 2122 in 2019 (P = 0.0145). During the second wave-related lockdown, there were 351 emergency patients compared with 526 patients in 2019 (P < 0.0001). Lens-induced glaucomas (50.4%) and neovascular glaucoma (20.6%) were the most common diagnoses during the first wave-related lockdown. During the unlock period, there was a greater proportion of neovascular glaucoma (P = 0.0123). The second wave-related lockdown had a greater proportion of phacolytic glaucomas (P = 0.005) and acute primary angle closure (P = 0.0397) patients. Conclusion: The study demonstrates that emergency glaucoma care was grossly underutilized by the people during the lockdowns. Trivial conditions like cataracts or retinal vascular diseases if not treated appropriately may progress to become emergencies in the future. [ABSTRACT FROM AUTHOR]

Purpose: To study the clinical and demographic profile of patients less than 40 years of age presenting to glaucoma services including the reasons for referral.Methods: Patients in the age group of 5 to 39 years, visiting the glaucoma clinic, who were either suspected to have glaucoma or who had been newly/previously diagnosed with glaucoma were included in the study. After informed written consent, basic demographic details of the participants including age, gender, education, socioeconomic status, and family history were obtained. A comprehensive ophthalmological evaluation was performed by glaucoma specialists.Results: The proportion of glaucoma in the study population (n = 384) was found to be 31.25%, and the incidence of glaucoma among new patients was found to be 11.9%. Among all glaucomas (n = 120), 44.2% of patients had secondary glaucomas, 27.5% had primary glaucomas, and 28.3% had congenital glaucomas. Also, 67.3% of all glaucoma patients were males. Newly diagnosed glaucoma patients presented with a mean intraocular pressure (IOP) of 32.9 mmHg and mild-moderate disc damage with a mean cup-disc ratio of 0.65. Nearly one-third of them had a presenting visual acuity worse than 5/60. The most common reason for referral was raised IOP. Univariate and multivariate analysis revealed that the odds of developing glaucoma were less in females (P = 0.04) and in patients with a higher standard of living index (P < 0.001).Conclusion: One-third of the patients had glaucoma and another one-third were suspects. Secondary glaucomas are more common than primary/congenital glaucomas. A comprehensive eye evaluation is a must, especially in those with predisposing factors. [ABSTRACT FROM AUTHOR]

Purpose: To compare the visual outcomes and intraoperative complications between phacoemulsification and manual small-incision cataract surgery (MSICS) in cases of posterior polar cataract (PPC).Methods: A retrospective study was carried out involving 142 patients (164 eyes) with PPC who underwent cataract surgery between January and December 2017. Data collected include the demographic details, preoperative uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), type of cataract, intraocular pressure, anterior and posterior segment findings, type of surgery performed, intraoperative complications, postoperative UCVA on the first day, UCVA and BCVA at 1 month after surgery, complications, and resurgery details.Results: In total, 90 patients (107 eyes) underwent phacoemulsification, and 52 patients (57 eyes) underwent MSICS. There was no significant difference in the mean age, sex, and type of PPC between the two groups (P = 0.326, 0.852, and 0.220, respectively). Patients who underwent phacoemulsification had significantly better preoperative BCVA (P = 0.002). The BCVA on first postoperative day and 1 month after surgery was better in the phacoemulsification group than in the MSICS group (P < 0.001 and 0.002, respectively). The overall incidence of posterior capsular rupture (PCR) was 11.6%, which included the 10.3% in phacoemulsification and 14.0% in MSICS. There was, however, no significant difference in the rates of PCR between the two groups (P = 0.506).Conclusion: Phacoemulsification delivered better postoperative visual outcomes than MSICS in PPC patients, whereas the complication rates were similar between the two groups.

In developing countries, manual small-incision cataract surgery (MSICS) has surfaced as the cost-effective alternative to phacoemulsification. The Simcoe irrigation-aspiration cannula was developed nearly 40 years ago and is still the most frequently employed tool for cortex aspiration. Although it stands unsurpassed, here we attempt to introduce an addition to the existing Simcoe cannula to achieve a dynamic and controlled vacuum with the added advantage of less physical strain and an effective volume of aspiration. The vacuum-assisted cortex removal device is based on a simple spring action mechanism, where the relaxation of the spring pushes the plunger up and thereby generates a controlled vacuum.

Purpose: To compare the short-term outcomes of combined phaco-emulsification with posterior chamber intra-ocular lens and mitomycin augmented trabeculectomy in patients with pseudo-exfoliation glaucoma (PXFG) versus primary open-angle glaucoma (POAG).Methods: A total of 144 eyes of 144 patients were enrolled in this prospective interventional comparative study, 72 each of which had PXFG and POAG, respectively. All patients underwent twin-site combined phaco-trabeculectomy at a tertiary eye center in India between December 2017 and December 2018 and were followed up for a period of 12 months. The main outcome measures were intra-ocular pressure (IOP), best corrected visual acuity (BCVA), total surgical time, rate of intra-operative and post-operative complications, and the number of ocular hypotensive medications needed. Success rates were determined via Kaplan-Meier survival analysis.Results: The mean age was 63.9 ± 7.9 years in the POAG group and 66.4 ± 6.8 years in the PXFG group (P - 0.04). The baseline BCVA, IOP, and cup-disc ratio were comparable between two groups. Intra-operative complications and post-operative outcomes were comparable between the two groups. There was a significant drop in anti-glaucoma medications in both groups. Six patients, three (4.2%) in each group, were lost to follow-up after 6 months. Three patients (4.2%) in PXFG needed additional glaucoma intervention for controlling IOP, one patient needed a non-valved glaucoma drainage device, and two patients required diode cyclo-photocoagulation within the follow-up period.Conclusion: Patients with PXFG had a longer surgical time than POAG. Similar success and complication rates were observed following combined twin-site phaco-trabeculectomy in both POAG and PXFG at 1 year. Combined glaucoma surgery resulted in good IOP control, improvement in BCVA, and lower requirement of ocular hypotensives in both the groups. [ABSTRACT FROM AUTHOR]

The foundation of an ophthalmologists' microsurgical career begins in the wet lab. Training on donor cadaveric, animal like goat or pig eyes provide the most realistic surgical environment, however, the availability of a donor's eyes for practice is limited. This scarcity is further escalated in this current coronavirus disease 2019 pandemic where eye donations have decreased. Even among those eyes which find their way into the wet lab, quite a few would have collapsed significantly making training difficult. Therefore, we looked at ways to salvage these collapsed globes. We describe a novel way of salvaging the collapsed eyeballs by injecting formalin in slow boluses into the vitreous cavity. The longer maintenance of the globe integrity without necessitating repeated injections facilitates better quality of surgical training and optimal utilization of these eyes. [ABSTRACT FROM AUTHOR]

Purpose: To understand the perspectives of physicians regarding the role of webinars on continuing medical education.Methods: An online survey comprising of 34 questions in nine sections was conducted using Google Forms. The link for the questionnaire was shared via e-mail and social media to practicing physicians. The survey accepted responses from September 10, 2020, to September 30, 2020.Results: In total, 509 ophthalmologists and 91 physicians from other specialties participated in the survey. The physicians were predominantly employed in nongovernmental institutes (25%) or were in private practice (33.2%). The preference was to attend a weekend webinar (62.8%), in the evening (52.8%), not extending more than 2 hours (97.7%), by ≤3 reputed national speakers (89.8%), each given 15 to 30 minutes for their presentation, and the topic being clinical or surgical skill demonstration (47.5%) or recent advances (39.5%). The residents were perceived to be the most benefited (65.3%). There was an equal preference for watching a webinar live or recorded (50.7% vs. 49.3%). Zoom Video Communications, Inc., was described as the platform that offers the best experience (43.8%). Webinars were considered to be better than conferences or continuing medical education (CME) activities (55.8%). The majority (43.8%) also preferred to get CME credit points by attending paid webinars. However, the broad consensus was that webinars should not completely replace the conferences (42.5%).Conclusion: Our survey evaluated the participants' perspective and the advantages and the disadvantages of a webinar and provides suggestions for the conduct of an ideal webinar with maximum active participation. Future programs would greatly be benefited by this survey. [ABSTRACT FROM AUTHOR]

Background: Topiramate is a drug commonly used by physicians. However, it has various systemic and ocular adverse effects. Bilateral angle closure crisis is a potentially blinding adverse reaction that is seldom reported in non-ophthalmic journals. Objective: This article aims to report a case series of topiramate-induced angle closure crisis in the eyes. Methods and material: Most patients presented to us with blurred vision and high intra-ocular pressure within days of starting topiramate tablet for headache. However, the attack resolved in those who presented early with prompt treatment, which included stopping topiramate. Conclusions: Physicians prescribing topiramate must be well aware of this potentially blinding adverse effect. Educating the patient about this possible side effect is important. Timely referral and treatment can prevent blindness in these individuals. [ABSTRACT FROM AUTHOR]

Among 20 million cataract surgeries being performed worldwide every year, approximately 5% are being complicated by posterior capsule rent or zonular dialysis. Intraocular lens (IOL) implantation in such cases with intraoperative complications is quite challenging. Our next course of action is to place the IOL in the ciliary sulcus, however, there is a risk of IOL drop into the vitreous in cases of inadequate support. We have described a novel idea of using a suture material through the dialling hole of a three-piece rigid IOL which can be used as a leash to reduce the risk of IOL drop during implantation in such cases. This technique could also be used during sutureless scleral fixated IOL and retro-pupillary iris claw lens implantation. We found that in 90 consecutive patients where this technique was used, there was no incidence of IOL drop or retinal detachment. [ABSTRACT FROM AUTHOR]

An asymptomatic 6-year-old boy was identified in our school screening camp with defective vision in both eyes and referred to us for refractory error evaluation. He was found to have corneal edema as a consequence of very high intraocular pressure (IOP) in both the eyes. On further evaluation, no congenital ocular anomalies which could lead to IOP elevation were found. He had earlier been diagnosed with acute lymphoblastic leukemia at 3 years of age and was on repeated cycles of systemic steroid therapy. Consequent to this, the child had developed raised IOP and steroid-induced secondary open-angle glaucoma with irreversible damage of the optic nerve in both eyes. He was started on topical anti-glaucoma medications and his IOP was brought under control with no worsening of optic nerve damage. This report highlights the possibility of steroid-induced glaucoma in the pediatric age group due to systemic steroid therapy and the necessity for timely referral to the ophthalmologist to avoid needless and irreversible blindness due to glaucoma.

Purpose To study the anatomic and functional outcome of air descemetopexy in postcataract surgery Descemet's membrane detachment (DMD). Design Retrospective study. Methods Setting: Institutional. Study population: Records of 112 patients who underwent air descemetopexy for postcataract surgery sight-threatening DMD at Aravind Eye Hospital, Pondicherry, between January 2013 and December 2015 were studied. Main outcome measures: Anatomical outcome refers to reattachment of the Descemet's membrane (DM). Functional outcome was given by the best-corrected visual acuity. Results The mean age was 66.47±8.46 (SD) years, the male to female ratio was 45:67. The incidence of DMD was more in extracapsular cataract extraction (0.26%) and manual small incision cataract surgery (0.11%) than phacoemulsification (0.04%) (p=0.005 and p<0.0001). DMD was more common among surgical trainees (0.17%) than consultants (0.07%) (p≤0.0001). After primary air descemetopexy, 78 (71%) out of the 110 patients had DM reattachment. The complications noted after descemetopexy include persistent DMD (21.8%), corneal decompensation (7.3%), appositional angle closure (18%), pupillary block with air (2.7%) and uveitis (2.7%). Age, sex and timing of intervention did not influence the reattachment rate. Fifteen patients underwent repeat air descemetopexy for persistent DMD among whom nine (60%) had successful reattachment. Almost 75% of patients had vision better than 6/18 1 month after anatomically successful descemetopexy. Conclusion Air descemetopexy is a safe and efficient modality of treatment of DMD and should be tried even in patients with severe DMD before planning a major surgery like endothelial keratoplasty.

Nevertheless, a study from Taiwan found that RP patients had 3.6-fold greater odds of having acute angle closure.[[9]] Even in the current study, the prevalence of PACG in RP patients was higher than in the general population. The association of primary angle-closure disease (PACD) and retinitis pigmentosa (RP) is debatable. The study notes that 5.9% of RP patients over 10 years of age had some form of PACD.

Background: Artificial Intelligence (AI) is an area of computer science that encompasses the creation of intelligent machines that work and react like humans. It deals with the development algorithms that seek to simulate human brain and also mimic cognitive functions typically associated with the human mind such as learning and problem solving.Purpose: Do we need artificial intelligence in Glaucoma? Glaucoma is the second most common cause of blindness in the world. Its prevalence was over 60 million in 2010 and over 80 million by 2020. It is so common, yet so easily overlooked. More importantly, about 50% of patients in developed countries and 90% in developing countries are unaware of having glaucoma. Early detection can delay the progression of glaucoma. Hence the time is ripe to advovate glaucoma screening.Synopsis: The application of AI in ophthalmology mainly concentrates on the diseases with a high incidence, such as diabetic retinopathy, age-related macular degeneration, glaucoma, retinopathy of prematurity, age-related or congenital cataract etc AI involves mainly 1. machine learning that are algorithms with the ability to learn without being explicitly programmed and 2. deep learning in which artificial neural networks adapt and learn from vast amounts of data. But there are limitations to screening - such as disparity between ophthalmologist:patient ratio and also the availability of the specialty services. The large amount of data acquired from patients makes it nearly impossible for ophthalmologists to screen them with equal efficacy and consistency.Highlights: AI in glaucoma aims at including factors such as clinical data, genomic data, life style behaviors, risk factors, and medical history to predict the risk of developing glaucoma, help customise the most appropriate management protocol for a given patient, and estimate prognosis and surgical success.Video Link: https://youtu.be/IwYS7wDMhkY.

Posterior polar cataract causes significant blurring of vision since it is at the nodal point of the eye and thus the patient presents earlier for cataract surgery. Despite comparatively smaller cataract and rapid recent developments in cataract surgery, there are significant surgical challenges due to preexisting weak or dehiscent posterior capsule. Clin Exp Ophthalmol 2010;38:857-61. 8 Pavan Kumar G, Krishnamurthy P, Nath M, Baskaran P, Janani M, Venkatesh R. Can preoperative anterior segment optical coherence tomography predict posterior capsule rupture during phacoemulsification in patients with posterior polar cataract?. [Extracted from the article]

Pseudoexfoliation Syndrome (PXFS) is considered a systemic disorder with significant ocular manifestations ranging from corneal decompensation, non-dilating pupil, zonular weakness, subluxated lens, and glaucoma. PXFS may lead to increased complications during routine cataract surgery. Zonular dialysis is a common complication during or after cataract surgery in such patients. However, not all patients with pseudoexfoliation are at a higher risk. We hypothesize that there is an inverse correlation between the maximum pupillary dilation and the degree of zonular disintegration. Available evidence supporting the hypothesis is discussed. We propose a new clinical classification for predicting the zonular strength based on the maximum pupillary dilation so that it can serve as a guide to identify PXFS patients who are at high risk of complications during or after cataract surgery.

Purpose: TO assess perceptions and implications of COVID-19 infection across the spectrum of individuals with visually impairment (VI) and those with normal sight., Design: Prospective cross-sectional comparative study., Methods: Setting: institutional., Patients: 232 patients and their caregivers. Four groups were created based on better eye characteristics: blind (best-corrected distance visual acuity [BCDVA] <3/60 or visual field <10 central degrees); severe VI (BCDVA ≤3/60 to <6/60; vertical cup-to-disc ratio ≥0.85 or neuroretinal rim width ≤0.1); moderate VI (BCDVA ≤6/60 to <6/18); or no or mild VI (controls: BCDVA ≥6/18) based on International Classification of Diseases-10 criteria and Foster and Quigley's consensus definition of glaucoma., Procedure: telephone questionnaires., Main Outcome Measures: differences in perceptions and implications of COVID-19 infection across various levels of VI. Caregiver perceptions were a secondary outcome measure., Results: Surveys were completed by 232 participants, with 58 participants in each VI group. Mean age was 58.9 ± 13.2 years old. Greater degrees of VI were associated with older age (P = .008) and lower education level (P = .046). Blind participants more commonly perceived vision as a risk factor for contracting COVID-19 (P = .045), were concerned about access to health care (P <.001), obtained news through word of mouth (P <.001), and less commonly wore masks (P = .003). Controls more commonly performed frequent handwashing (P = .001), were aware of telemedicine (P = .029), and had fewer concerns about social interactions (P = .020) than groups with substantial VI. All caregivers reported more frequent patient care since the COVID-19 pandemic began., Conclusions: The pandemic might have had a disproportionate impact on the visually impaired, and evidence-based assessments of COVID-19 health outcomes in this population are warranted., (Copyright © 2021 Elsevier Inc.

Aim: To understand the barriers in utilisation of low vision assistive products (LVAPs) from the perspective of patients with low vision., Methods: Patients referred to low vision clinic in a tertiary eye care hospital in India who were prescribed LVAPs but were un-willing to accept the products were interviewed using questionnaires. Data pertaining to the age, diagnosis, gender, occupation, preferred LVAPs, patient's perception of vision loss and the primary reason for non-acceptance of LVAPs were analysed., Results: A total of 235 among the 413 patients who noticed improvement in visual performance with LVAPs were unwilling to utilise these products. The questionnaire revealed that 53% of the patients who felt they were not candidates for LVAPs were experiencing severe visual impairment (p < 0.02). Non-acceptance was highest (68.6%) in patients < 15 years of age. The most common causes of non-acceptance were social stigma in patients < 40 years (41.3%; p < 0.0001), fear of loss of employment in patients 41-60 years (26.6%; p < 0.01) and low necessity in patients > 60 years (25%; p < 0.001). Denial of the magnitude of their illness was more common in patients above 60 years (16.5%). Non-acceptance rate was lowest for macular disorders (39.6%) and highest for retinitis pigmentosa (81%). Among devices, hand and stand magnifiers had the lowest non-acceptance rate (41%). Telescopes and electronic devices had the highest rate of non-acceptance (92% and 89%, respectively)., Conclusion: Reasons for poor utilisation of LVAPs are multifactorial extending beyond affordability or accessibility. Knowledge of these barriers can help in creating content for awareness campaigns among patients, healthcare professionals and general society. Further research is necessary on the psychological and psycho social contributors to this process.
