Xen45 gel stent ab interno trimming for ostium occlusion: case report.

BACKGROUND: Despite the XEN gel stent low-risk profile, various complications following the implant have been described, including internal and external occlusion, with a consequent postoperative rise in intraocular pressure (IOP). In this case report we aimed to present a XEN45 stent internal occlusion successfully treated by trimming in situ its proximal end with a 25 G vitreous scissors using a bimanual technique. CASE PRESENTATION: A 63-year-old male patient affected by primary open angle glaucoma (IOP = 25 mmHg) and a full thickness macular hole in his right eye, underwent ab-interno Xen gel stent implantation and, 1 month later, a 25 G vitrectomy surgery. Despite a significant IOP reduction after stent implant, 6 days after vitrectomy, IOP increased (25 mmHg) and the conjunctival bleb flattened following occlusion of stent internal ostium by a clot of presumed fibrinous material. The Nd:YAG laser failed to remove the clot, so that we decided to snip a small bit of the proximal end of the Xen tube (about 0,5 mm length) with a 25 G vitreous scissors, using a bimanual technique. In the postoperative day 1 and month 1, the IOP was 8 mmHg and 12 mmHg, respectively. The Anterior Segment OCT confirmed a functional, layered, filtering bleb, and the normal appearance and patency of the XEN proximal segment. No side effects from the intervention were observed. CONCLUSIONS: Ab interno trimming with vitreous scissors of the occluded proximal end of the XEN stent may represent a safe, rapid and efficient method to restore aqueous humor subconjunctival drainage.

Optical coherence tomography in forensic sciences: a review of the literature.

Optical coherence tomography (OCT) is an interferometric imaging technique that has revolutionized clinical ophthalmology since the first half of the 1990's. Despite this approach being successfully employed in ophthalmology and having great potential in forensic cases, its use in different forensic fields appears to be quite limited. In this review we reviewed the scientific literature regarding the application of OCT in forensic science and legal medicine from 1995 to 2019. Our research showed the usefulness of this approach for the study of coronary injuries, postmortem ocular changes, forensic entomology, and several other applications of specific forensic interest (the study of blood stains, fingerprints, and hair bulbs for personal identification, as well as the study of materials found in the crime scene for comparation, or anti-fraud investigation). The creation of specific 'ad hoc' devices and a better knowledge of this type of technology by pathologists will be a fundamental step to continue to develop the use of OCT forensic fields.

Ocular surface and respiratory tract damages from occupational, sub-chronic exposure to fluorspar: case report and other considerations.

OBJECTIVES: To report the ocular surface and respiratory tract damages due to a sub-chronic (3 months), occupational exposure to fluorspar dust in case of inconsistent use of personal protective equipment. METHODS: A 50-year-old man was referred to our clinic with bilateral conjunctival injection, ocular foreign body sensation and symptoms of ocular discomfort. He reported having 3 days before an urgent hospital admission for dyspnoea with odynophagia, hyposmia, nausea, vomiting, headache and asthenia. Otorhinolaryngological examination revealed a severe hypertrophic rhinopharyngitis and a significant decrease in overall sensitivity to olfactory stimuli. General anamnesis was negative for previous diseases or medication use. RESULTS: Ocular examination revealed a diffuse injection of the ocular surface with some areas of conjunctival and limbal ischaemia, a best-corrected visual acuity of 20/25 in both eyes, an intraocular pressure of 23 and 21 mmHg, respectively, in the right and in the left eyes, and a normal fundus oculi. Assessment of the tear film and ocular surface showed the presence of dry eye disease. Based on medical history and clinical tests, initial diagnostic hypothesis was ocular surface burn due to chemical exposure, i.e. to fluorspar. Therefore, anterior segment fluorescein angiography was performed to confirm the extension of conjunctival and limbal ischaemia. Thus, ocular ischaemia was detected in approximately 10 clock hours of limbus and in 50% of conjunctiva. CONCLUSIONS: The present work remarks the importance of using protective equipment for preventing ocular and respiratory tract damages in workers occupationally exposed to the 'acid-grade fluorite'.

Morphological analysis of corneal findings modifications after death: A preliminary OCT study on an animal model.

The aim of this work was to describe, for the first time, the morphological modifications, in a three-dimensional mode, of the central cornea at different intervals since death. The study design involved the analysis of 30 eyes (15 heads) of female, adult sheep (>2 years) sacrificed at a local slaughterhouse. The eyes, after animal decapitation, were examined in situ, without enucleation. Ocular globes were stored at well-known temperature (within a range of 12-22 °C) and humidity (within a range of 50-60%). The instrumental analysis was executed using a portable spectral-domain OCT (SD-OCT) system (iVue SD-OCT, Optovue Inc, Fremont, CA) calibrated to the corneal mode. OCT imaging was performed at different time-points since death. Pachymetric map, morphological and ultrastructural analysis (epithelium, stroma, and endothelium), were performed for each time-point. After an initial thinning of tissues and an enhancement of epithelial reflectivity, stromal thickness increased from the 2nd up to the 6th hour. Subsequently, a new trend incorneal thinning was observed in association with the appearance ofone or more demarcation lines between the anterior andposterior stroma. After the 12th hour, a recurrence of corneal swelling was detected in association with thedelamination of stromal tissue. Since the 24th hour, the epithelium disappeared in 50% of cases and the anterior chamberdepth progressively decreased. At the 48th hour, various ocular structures showed the onset of putrefaction processes, such as theappearance of hyper-reflective dots in anterior chamber, iridocorneal contact, and the massive vacuolization of theposterior stroma until the total delamination. The portable OCT system is a useful approach for in situ postmortem corneal examination, and it may be potentially applied for the selection of donor cornea in transplantology and for the determination of post-mortem intervals in forensic medicine.

An uncommon case of intermittent Pourfour du Petit Syndrome associated with acute angle-closure glaucoma successfully treated by laser iridotomy.

PURPOSE: To describe a case of acute angle-closure glaucoma secondary to intermittent mydriasis related to Pourfour du Petit Syndrome caused by tracheal deviation. MATERIALS AND METHODS: A 70-year-old Caucasian woman visited the Emergency Room of the University Eye Clinic complaining of blurring of vision and difficulty to move superior eyelid in her right eye. Examination revealed reactive mydriasis, and upper lid retraction on the right side. The rest of the ophthalmological examination was normal, and a cranial computed tomography (CT) did not identify any abnormalities. A cervical CT showed the presence of an accentuated lateral right convex deviation of the trachea, attributable to a fibrothorax. A right Pourfour du Petit syndrome was suspected. Although the mydriasis had in the meantime vanished, the patient was admitted to the Neurological Clinic. RESULTS: Five days later she suffered acute pain in her right eye. Ophthalmological examination of the right eye revealed conjunctival hyperemia, marked corneal edema, reduced depth of anterior chamber, permanent mydriasis. As assessed by Goldmann applanation tonometry, intraocular pressure (IOP) was 48 mm Hg. Fundus examination was normal in both eyes. Gonioscopy revealed angle closure in all quadrants. Slit lamp examination of the contralateral eye was normal; IOP was 10 mm Hg. After hypotensive medical therapy, iridotomy with YAG laser was performed. Thereafter, IOP stabilized at 12 mm Hg. CONCLUSIONS: This is the first report in the literature of a case of acute angle-closure glaucoma secondary to mydriasis related to Pourfour du Petit Syndrome caused by tracheal deviation.

Meta-analysis of genome-wide association studies in five cohorts reveals common variants in RBFOX1, a regulator of tissue-specific splicing, associated with refractive error.

Visual refractive errors (REs) are complex genetic traits with a largely unknown etiology. To date, genome-wide association studies (GWASs) of moderate size have identified several novel risk markers for RE, measured here as mean spherical equivalent (MSE). We performed a GWAS using a total of 7280 samples from five cohorts: the Age-Related Eye Disease Study (AREDS); the KORA study ('Cooperative Health Research in the Region of Augsburg'); the Framingham Eye Study (FES); the Ogliastra Genetic Park-Talana (OGP-Talana) Study and the Multiethnic Study of Atherosclerosis (MESA). Genotyping was performed on Illumina and Affymetrix platforms with additional markers imputed to the HapMap II reference panel. We identified a new genome-wide significant locus on chromosome 16 (rs10500355, P = 3.9 × 10(-9)) in a combined discovery and replication set (26 953 samples). This single nucleotide polymorphism (SNP) is located within the RBFOX1 gene which is a neuron-specific splicing factor regulating a wide range of alternative splicing events implicated in neuronal development and maturation, including transcription factors, other splicing factors and synaptic proteins.

Age-related macular degeneration and cognitive impairment show similarities in changes of neutral lipids in peripheral blood mononuclear cells.

Starting from previous studies showing that patients with cognitive deficit present neutral lipids (NLs) accumulation in cytoplasm of their peripheral blood mononuclear cells (PBMCs) and considering that there is epidemiological evidence linking age-related macular degeneration (AMD) to cognitive deficit, the first purpose of this study was to test whether neutral lipids also accumulated in PBMCs from AMD subjects. Moreover, the impact of statin use on AMD was explored and whether such use in AMD subjects was associated with NLs accumulation in PBMCs. The study was conducted on 222 subjects: 136 AMD (36 of which - 26.5% - using statins], 48 cognitive deficit (20 of which - 41.7% - using statins) and 38 healthy controls (4 of which -10.1% - using statins), AMD lesions were assessed from color fundus photographs. Mini-mental state examination (MMSE), demographics, lifestyle factors and medical history were collected at interview. MMSE score was categorized as normal (24-30), and impaired (<24), NLs content was evaluated by oil red 0 (ORO) staining method. ORO determination showed that neutral lipids were generally absent or very low (score between 0 and 1) in healthy controls while most of PBMCs from cognitive deficit and AMD had ORO staining levels scoring 2-4. Post hoc analysis (Bonferroni) in a one-way ANOVA revealed that ORO score was significantly higher in cognitive deficit and AMD subjects compared to healthy controls and in cognitive deficit compared to AMD. Bonferroni-test also showed that AMD subjects had significantly lower total cholesterol (TC) levels compared to healthy controls while high density lipoprotein-cholesterol (HDL-C) did not reach statistical significance. The results also revealed a significant higher number of statin-users in AMD compared to healthy controls. Likewise when cognitive deficit vs healthy controls was analyzed, the number of statin users were found to be significant higher in cognitive deficit than in healthy controls. There were no significant differences in statin use between AMD and cognitive deficit. Compared to healthy controls, statin use in cognitive deficit and AMD groups was significantly associated with ORO scores of 2-4. This data supports the hypothesis that AMD and cognitive deficit share similar complex pathophysiology and risk factors including NLs accumulation in their PBMCs, although this does not necessarily imply that one disease causes the other. In addition, they provide further evidence that statin use may increase the risk of AMD.

Anterior Segment Optical Coherence Tomography for Cases of High Intraocular Pressure Following XEN Implant for Glaucoma.

PRCIS: This study showed that the XEN patency should be verified by OCT imaging in cases of encapsulated blebs. Although fibrosis plays the principal role, humor aqueous flow reduction could affect the "spacer" effect that inhibits the fibroblast attachments. PURPOSE: To evaluate the application of the anterior segment optical coherence tomography (AS-OCT) imaging in studying the relationship between a low flow rate through the XEN63 and the development of a cystic bleb. METHODS: Retrospective case series of 3 eyes presenting a cystic bleb after an XEN63 implantation for uncontrolled intraocular pressure (IOP). Demographic and clinical data were obtained from medical records. The imaging findings, complications, and managements following the surgery were evaluated. RESULTS: Three patients, with an average age of 67.3 years, initially showed a patent stent lumen and a functional bleb after surgery. The IOP of all eyes increased on average at 28.3 days from the surgery, with a mean value of 39.66 mm Hg. The slit lamp examination showed a cystic bleb. The AS-OCT imaging confirmed the previous finding and revealed either a partial or total occlusion of the stent internal ostium. A Nd:YAG laser, in proximity to the ostium, was performed to resolve the obstruction. Although the AS-OCT imaging showed the device patency and the IOP immediately decreased, the latter became elevated again. Consequently, in all the cases, a further needling procedure was needed to achieve an adequate IOP reduction. Six months after the two-step procedure, the IOP averaged 13.33 mm Hg, the XEN63 lumens appeared cleared, and the blebs showed a functional morphology. No adverse events were observed. CONCLUSION: The development of a cystic bleb may result from an altered balance between the flow rate through the XEN63 and the fibrosis development in the postoperative healing process. A proper follow-up based on slit lamp biomicroscopy, IOP measurement, and AS-OCT imaging is advisable to estimate and manage a cystic bleb following XEN63 implantation.

No Changes in Keratometry Readings and Anterior Chamber Depth after XEN Gel Implantation in Patients with Glaucoma.

Background: This study aimed to compare keratometry and anterior chamber depth (ACD) changes after XEN implantation in primary open-angle glaucoma (POAG) cases over a 3-month follow-up period. Methods: Twenty patients with POAG who underwent XEN63 implantation, either standalone or combined with cataract surgery, were included. Preoperative data, including best-corrected visual acuity (BCVA), refraction, gonioscopy, ophthalmoscopy, intraocular pressure (IOP) evaluation, and axial length, were collected. Corneal topography and ACD measurements were assessed preoperatively and at postoperative days 1, 7, 15, 30, 60, and 90. Each patient's eye that underwent XEN surgery was included in the study group, with the fellow eye serving as a control. Results: In the study group, there was a significant decrease in IOP after XEN stent implantation at all investigated time intervals (p < 0.05). However, changes in mean ACD did not show statistically significant differences at any follow-up examination in both the study and control groups. Additionally, keratometry readings revealed no significant changes in total astigmatism or steep keratometry values in either group. Conclusions: XEN implantation in POAG cases resulted in a significant decrease in IOP over the 3-month follow-up period. However, there were no significant changes observed in mean ACD or keratometry readings, indicating stability in these parameters post-XEN implantation. These findings suggest that XEN implantation may be an effective option for IOP reduction without affecting corneal curvature or ACD in POAG patients.

Blepharospasm as a tardive manifestation of COVID-19 disease: A case report.

We report three cases of blepharospasms developed after a symptomatic COVID-19 infection, in order to describe a possible association between COVID-19 infection and essential blepharospasm. Blepharospasm could represent a late sign of COVID-19 infection (more than four weeks after the contagion) and may be triggered by the neurotropism of the coronavirus.

X-linked retinoschisis: OCT-angiography in two brothers from a four-generation family with a p.Arg197Cys pathogenic variant in the RS1 gene.

INTRODUCTION: X-linked juvenile retinoschisis (XLRS) is a rare genetic disease causing retinal splitting. The aim of this work is to describe the optical coherence tomography angiography (OCTA) features in two brothers affected by an hemizygous c.589C>T (p.Arg197Cys) pathogenic variant in exon 6 of the RS1 gene. CASE DECRIPTION: Each patient underwent a complete ophthalmological examination, including measurement of best corrected visual acuity, slit-lamp biomicroscopy, fundus color photographs, fundus autofluorescence and infrared imaging, fluorescein angiography, spectral-domain optical coherence tomography (SD-OCT) and optical coherence tomography angiography (OCTA). En Face SD-OCT and OCTA revealed the presence of two different pattern of cystic lesions, fusiform and oval, disposed on a petaloid or irregular manner in the perifoveolar area. A widening of the foveal avascular zone with interruption of the vascular arcades was clearly evident. Furthermore, a capillary drop-out was observed in the superficial plexus of the central retina, other than capillary ectasia in the deep capillary plexus. Straight gray lines were visible among the cysts. CONCLUSIONS: OCTA data herein described allow a detailed morphological evaluation of XLRS other than a quantitative assessment of retinal capillary flow in this disease. The retinal alterations that we have reported may be helpful to better understand this rare condition with OCTA being a sensitive technique to monitor the evolution of the disease and the response to potential future therapeutic approaches aimed to restore vision.

Compass Fundus-Guided Perimetry in Geographic Atrophy.

Purpose: To evaluate compass (CMP), a recently introduced device that combines scanning ophthalmoscopy, automated perimetry, and eye tracking, for fundus-guided perimetry (microperimetry) with the purpose of correlating perimetric retinal sensitivity (PRS) and retinal geographic atrophy (GA) features. Materials and Methods: A retrospective, cross-sectional study was performed in 56 eyes of 43 patients affected by GA. All patients underwent compass 10-2 perimetry, consisting of a full-threshold visual field on fundus photography and an infrared (IR) image of the central 30° of the retina. Data were exported to an Excel sheet. Binarization with black/white (B/W) variables was applied on the compass photo fundus and matched with visual field scores. Patients underwent autofluorescence (AF) and IR images (Heidelberg, Germany): CMP and Heidelberg IR images were homologated by using GIMP software (https://www.gimp.org), and then atrophic areas were manually measured with the ImageJ program. CMP perimetric grid was overlapped with AF and IR pictures by using GIMP, obtaining composite TIFF images, which were then analyzed with the ImageJ greyscale score (GSS) tool. A hyperautofluorescent halo was identified on the GA edges of some patients. Pearson's correlation between GA size on IR compass and IR Heidelberg and between GSS and PRS values has been calculated; the independent t-test was realized to calculate the correlation between GSS and B/W variables identified on the CMP photo fundus. The Spearman correlation between total deviation and pattern deviation was calculated. Results: The AUC-ROC score between CMP scores and B/W variables was 93,4%. The Spearman correlation between total deviation and pattern deviation was highly significant (p = 0,00). The correlation between AF GSS values and PRS was significant (p value = 0,00), the correlation between GSS of hyperautofluorescent points and PRS was significant (p value = 0,00), and the correlation between IR GSS and PRS was significant (p value = 0,00). The correlation between AF GSS and B/W variables was significant (p value = 0,002), the correlation between hyperautofluorescent points and B/W was not significant (p value = 0,40), and the correlation between IR GSS and B/W was significant (p = 0,00). Conclusions: Based on our preliminary results, compass seems to be a reliable, quick, and safe device for the anatomical and functional study of GA. The direct visualization of the visual field on the fundus photography as a background allows a precise assessment and clinical monitoring of this disease.

The Influence of Eyelid Position and Environmental Conditions on the Corneal Changes in Early Postmortem Interval: A Prospective, Multicentric OCT Study.

In the current study, using portable optical coherence tomography, we evaluated 46 corneas of 23 individuals in a multicenter setting during the first 17 h after death. Twenty-three eyes were kept open, and twenty three were kept closed. Furthermore, the experiment was carried out for 12 samples in summer and 11 in winter. Our data show that postmortem corneal alterations largely depend on the phenomena of dehydration (in particular in open eyes) and swelling of the stroma in closed eyes, probably due in the first phase to hypoxia/anoxia and subsequently to the passage by osmosis of the aqueous humor from the anterior chamber to the corneal tissue. Our findings could have significant repercussions in forensic pathology for estimating the postmortem interval and transplantation to optimize the conservation of the tissue before the explant.

Non-infectious uveitis burden on quality of life and work impairment assessed through different psychometric questionnaires.

BACKGROUND: The purpose of this study was to evaluate the association between a novel psychometric 12-item questionnaire (U-qest) and other validated questionnaires to assess quality of life and work impairment in patients with non-infectious uveitis. METHODS: Data were collected at baseline and 3 months postbaseline using U-qest and two other validated questionnaires: The National Eye Institute 25-Item Visual Function Questionnaire (VFQ-25) and the 12-Item Short-Form Health Survey (SF-12). RESULTS: A total of 136 patients (52.2% female) aged 47.9 ± 14.8 years (mean ± SD) were enrolled in 14 uveitis referral centres. U-qest correlated moderately with VFQ-25 and SF-12 at baseline and at 3 months. Both U-qest and VFQ-25 scores improved as disease improved; however, U-qest also detected improvement in patients for whom VFQ-25 scores did not improve. Disease activity was shown to significantly affect activity impairment. Patients and physicians expressed positive perceptions regarding the use and benefit of this instrument. U-qest showed very good reliability in terms of internal consistency (Cronbach's alpha = 0.91). CONCLUSIONS: U-qest can be considered a useful tool to assess the burden of uveitis on quality of life.

The "Quarantine Dry Eye": The Lockdown for Coronavirus Disease 2019 and Its Implications for Ocular Surface Health.

The pandemic of coronavirus disease 2019 (COVID-19) has led many countries of the world to impose a series of containment measures such as lockdowns (mass quarantines), curfews or similar restrictions (eg, stay-at-home orders, or shelter-in-place orders). All these restrictions were established in order to limit spread of COVID-19. Thus, approximately 3.9 billion people worldwide were under lockdown by early April 2020. During this time (home confinement), some solutions have been proposed by experts to improve work and school productivity, including smart working and online school lessons. However, many of the restrictive measures are likely to act as predisposing factors for dry eye disease (DED), directly or related to sick building syndrome (SBS). Herein, we discuss the implications of quarantine measures on eye health, in particular on DED associated with SBS, and introduce some potential preventive strategies for lockdown-related ocular surface disorders. Several risk factors are implicated in their pathogenesis, including environmental changes (eg, air quality) and modifications in personal behaviors (eg, the abuse of digital devices, malnutrition, and sleep/psychiatric disorders). Considering a number of predisposing factors for DED, it is possible to state that patients under lockdown are at risk of ocular surface alterations. Accordingly, the COVID-19 pandemic era is expected to determine an increase in dry eye patients all around the world (a new phenomenon that we propose to name the "quarantine dry eye") in the event that the restrictive measures will be recursively extended over time.

Dual Corneal-Graft Rejection after mRNA Vaccine (BNT162b2) for COVID-19 during the First Six Months of Follow-Up: Case Report, State of the Art and Ethical Concerns.

Present mass vaccination against Coronavirus Disease-19 (COVID-19) is the most widely used health policy and the most promising approach to curb the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic globally. However, new side effects are emerging from the mass vaccination not described during the experimental stages. In the present study, we discuss a case of acute corneal graft rejection, which has occurred 25 years after transplantation and 13 days after the administration of the BNT162b2 vaccine (Comirnaty, BioNTech/Pfizer), which was followed-up for a period of six months. In this period, the corneal inflammation appeared twice but was successfully managed with topical therapy and supplementation of Vitamin D. A risk of corneal graft rejection must be included in the list of potential vaccine complications, in order to inform the transplanted patient to undergo a preliminary and a follow-up ocular examination, and eventually to include corneal graft in the list of contraindications to vaccination.

Postmortem Ocular Findings in the Optical Coherence Tomography Era: A Proof of Concept Study Based on Six Forensic Cases.

Postmortem analysis of the ocular globe is an important topic for forensic pathology and transplantology. Although crucial elements may be gathered from examining cadaveric eyes, the latter do not routinely undergo in-depth analysis. The paucity of quantitative and objective data that are obtainable using current, invasive necroscopic techniques is the main reason for the limited interest in this highly specialized procedure. The aim of the current study is to describe and to object for the first time the postmortem ocular changes by mean of portable optical coherence tomography for evaluating ocular tissues postmortem. The design involved the postmortem analysis (in situ, and without enucleation) of 12 eyes by portable spectral-domain Optical Coherence Tomography. The scans were performed, in corneal, retinal and angle modality at different intervals: <6 h, 6th, 12th, and 24th hour and after autopsy (25th-72nd hour). The morphological changes in the cornea, sclera, vitreous humor and aqueous humor were easy to explore and objectify in these tissues in first 72 h postmortem. On the other hand, the "in situ" observation of the retina was difficult due to the opacification of the lenses in the first 24 h after death.

INTRAVITREAL AFLIBERCEPT IN THE TREATMENT OF POLYPOIDAL CHOROIDAL VASCULOPATHY ASSOCIATED WITH MORNING GLORY SYNDROME.

PURPOSE: To describe an unusual case of polypoidal choroidal vasculopathy secondary to morning glory syndrome successfully treated with three aflibercept intravitreal injections. METHODS: Case report. RESULTS: A 68-year-old white man presented with a 2-month history of diminished vision of his left eye. Fundus examination showed a morning glory syndrome disk anomaly with some perimacular subretinal hemorrhages and lipid depositions. Fundus autofluorescence, fluorescein and green indocyanine angiography, spectral domain optical coherence tomography, and optical coherence tomography angiography were performed and confirmed the presence of a juxtapapillary polypoidal choroidal vasculopathy with intraretinal and subretinal fluid. Patient underwent 3 monthly intravitreal injections of aflibercept and at 4-month follow-up visit, multimodal imaging findings did not show any kind of neovascular lesion activity. CONCLUSION: Polypoidal choroidal vasculopathy can occur in morning glory syndrome and it can be successfully treated with anti-vascular endothelial growth factor intravitreal injections of aflibercept.

Safety Recommendations and Medical Liability in Ocular Surgery during the COVID-19 Pandemic: An Unsolved Dilemma.

Ocular surgery is one of the most performed medical procedures in the world. Its limitation or suspension, recursively extended over time, could be associated with a significant increase in the number of blind people worldwide. Indeed, cataract causes more than half of all cases of visual impairment in those countries with limited availability of means for performing eye operations (e.g., Africa or India). In this scenario, the pandemic of coronavirus disease 2019 (COVID-19) quickly resulted in the suspension or sharp reduction of various ophthalmic activities considered non-urgent, including lens replacement surgery or some intraocular injections. Despite the imperative need to continuously practice eye operations to avoid the abovementioned problems, there are currently little-shared and vague recommendations among the various countries on safety in operating rooms (for health care workers and patients) and poor legal protection for surgeons (potentially transmitting the COVID-19 infectious agent). Herein, we individuated and discussed some critical points in safety recommendations and medical liability. A paradigm shift for ocular surgery during the COVID-19 era is now mandatory. While telemedicine has been able to solve some problems in clinical ophthalmology, the lack of adequate health and legal protection for surgeons and patients may result in an excessive reduction in the volume of surgical interventions during a pandemic era and the immediately following period, thus determining inability to ensure health care to all patients.
