Abstract
Introduction Ruthenium-106 (Ru-106) brachytherapy is one of the commonest eye-sparing treatments for choroidal melanoma. These patients require long-term surveillance of the treated tumour remnant to ensure there is no local recurrence. New or progressive pigmented lesions in treated eyes are often regarded as suspicious - especially if there are concerns of extra-scleral extension. Case Presentations We present two cases of posterior choroidal melanoma treated five and 10 years previously with Ru-106. Both cases developed subconjunctival dark/black lesions on the anterior surface of the eye in the quadrant of the conjunctival peritomy during Ru-106 treatment. Both had similar findings on histopathology: black, non-organic, particulate foreign material of varying confluence deposited on elastin and collagen fibres. Energy dispersive X-ray microanalysis confirmed the material contained silver. Discussion The Ru-106 applicator consists of a radioactive core of Ru-106 encapsulated within pure silver as a radiation shield. During surgical insertion, stainless steel suture needles and forceps can occasionally scratch the applicator's silver eyelets and scatter microscopic particles of elemental silver into the operative field. These particles were likely deposited within the subconjunctival tissues of these patients during brachytherapy administration, leading to localised ocular argyrosis. Iatrogenic ocular argyrosis should be considered in the differential diagnosis of new pigmented lesions in patients treated with Ru-106 brachytherapy. This study is the first to unequivocally identify the cause of some post-brachytherapy ocular surface pigmentation as caused by silver.

Abstract
In this report the use of eye cosmetic products and procedures and how this represents a lifestyle challenge that may exacerbate or promote the development of ocular surface and adnexal disease is discussed. Multiple aspects of eye cosmetics are addressed, including their history and market value, psychological and social impacts, possible problems associated with cosmetic ingredients, products, and procedures, and regulations for eye cosmetic use. In addition, a systematic review that critically appraises randomized controlled trial evidence concerning the ocular effects of eyelash growth products is included. The findings of this systematic review highlight the evidence gaps and indicate future directions for research to focus on ocular surface outcomes associated with eyelash growth products.

Abstract
Occupational ocular argyrosis is a rare disorder associated with accumulation of silver in the eye due to its occupational exposure. A 39-year-old male patient, a silver utensils polisher for the past 30 years, presented with bilateral gradual diminution of vision (presently 20/200) for 2 years. His serum silver levels were raised and ocular examination revealed bilateral greenish brown corneal deposits and complicated cataract. Anterior segment optical coherence tomography (OCT) and confocal microscopy suggested deposition of silver in various corneal layers. Multifocal electroretinogram showed a generalized decrease in sensitivity of P1 waves. Increased internal aberrations on aberrometric profile favoured phacoemulsification followed by intraocular lens implantation in both eyes. Postoperatively, the visual gain of 20/20 and normal fundus picture on indirect ophthalmoscopy, macular OCT, and fundus autofluorescence favored good prognosis in both eyes.

Abstract
Argyria encompasses the different cosmetic alterations that can develop if enough silver particles deposit in a specific tissue, typically in the skin, ranging from localized dark-blue macules to a generalized slate-gray/bluish tinge following systemic absorption. This work aims to fully review the state of the art regarding pathophysiology, diagnosis, treatment, and relevant clinical and forensic features of argyria. Argyria has been diagnosed in a wide range of ages, both sexes and varied ethnicities, with no known individual predisposing factors. Ultraviolet radiation with subsequence increases of melanin production aggravates the discoloration due to a reduction in the silver deposits. Physical examination and silver exposure in the anamnesis can be highly suggestive of the diagnosis, but a histopathological analysis with Energy-Dispersive X-ray Spectroscopy is required to unequivocally determine the discoloration etiology. Safe and effective treatment has only been accomplished with laser techniques, though only a few cases have been reported and with limited follow-up time. In conclusion, argyria typically has an occupational or iatrogenic etiology. It should be suspected when a patient presents with typical skin or eye lesions. A seemingly viable treatment modality, with laser technology, is finally within the horizon.

Abstract
The popularity and variety of temporary and permanent periocular aesthetic treatments has increased over the past decade. Patients frequently present to eye clinics with ocular complications and side effects following these treatments, their severity ranging from ocular irritation from dry eyes to visual loss from vascular occlusion. A careful, thorough history is essential, as many patients may not associate aesthetic procedures with ocular complications, and some may be embarrassed to disclose this information. All ophthalmologists should understand the potential ocular sequelae of these treatments and be able to initiate treatment in sight-threatening cases. Wesummarises the current literature on ophthalmic complications of the most common periocular aesthetic treatments.

Abstract
SIGNIFICANCE Think Tank 2019 affirmed that the rate of infection associated with contact lenses has not changed in several decades. Also, there is a trend toward more serious infections associated with Acanthamoeba and fungi. The growing use of contact lenses in children demands our attention with surveillance and case-control studies. PURPOSE The American Academy of Optometry (AAO) gathered researchers and key opinion leaders from around the world to discuss contact lens-associated microbial keratitis at the 2019 AAO Annual Meeting. METHODS Experts presented within four sessions. Session 1 covered the epidemiology of microbial keratitis, pathogenesis of Pseudomonas aeruginosa, and the role of lens care systems and storage cases in corneal disease. Session 2 covered nonbacterial forms of keratitis in contact lens wearers. Session 3 covered future needs, challenges, and research questions in relation to microbial keratitis in youth and myopia control, microbiome, antimicrobial surfaces, and genetic susceptibility. Session 4 covered compliance and communication imperatives. RESULTS The absolute rate of microbial keratitis has remained very consistent for three decades despite new technologies, and extended wear significantly increases the risk. Improved oxygen delivery afforded by silicone hydrogel lenses has not impacted the rates, and although the introduction of daily disposable lenses has minimized the risk of severe disease, there is no consistent evidence that they have altered the overall rate of microbial keratitis. Overnight orthokeratology lenses may increase the risk of microbial keratitis, especially secondary to Acanthamoeba, in children. Compliance remains a concern and a significant risk factor for disease. New insights into host microbiome and genetic susceptibility may uncover new theories. More studies such as case-control designs suited for rare diseases and registries are needed. CONCLUSIONS The first annual AAO Think Tank acknowledged that the risk of microbial keratitis has not decreased over decades, despite innovation. Important questions and research directions remain.

Abstract
Colloidal silver used as a suspension for (alternative) therapeutic purposes or silver exposure due to environmental or working conditions can lead to irreversible deposits of silver granules in the skin (bluish-gray hue of the skin), mucosa, cornea, retina and internal organs. Silver-induced discoloration of the conjunctiva should therefore be taken into account when a bluish-gray discoloration raises the suspicion of conjunctival melanoma.

Abstract
: Bacterial biofilm on medical devices is difficult to eradicate. Many have capitalized the anti-infective capability of silver ions (Ag+) by incorporating nano-silver (nAg) in a biodegradable coating, which is then laid on polymeric medical devices. However, such coating can be subjected to premature dissolution, particularly in harsh diseased tissue microenvironment, leading to rapid nAg clearance. It stands to reason that impregnating nAg directly onto the device, at the surface, is a more ideal solution. We tested this concept for a corneal prosthesis by immobilizing nAg and nano-hydroxyapatite (nHAp) on poly(methyl methacrylate), and tested its biocompatibility with human stromal cells and antimicrobial performance against biofilm-forming pathogens, Pseudomonas aeruginosa and Staphylococcus aureus. Three different dual-functionalized substrates-high Ag (referred to as 75:25 HAp:Ag); intermediate Ag (95:5 HAp:Ag); and low Ag (99:1 HAp:Ag) were studied. The 75:25 HAp:Ag was effective in inhibiting biofilm formation, but was cytotoxic. The 95:5 HAp:Ag showed the best selectivity among the three substrates; it prevented biofilm formation of both pathogens and had excellent biocompatibility. The coating was also effective in eliminating non-adherent bacteria in the culture media. However, a 28-day incubation in artificial tear fluid revealed a ~40% reduction in Ag+ release, compared to freshly-coated substrates. The reduction affected the inhibition of S. aureus growth, but not the P. aeruginosa. Our findings suggest that Ag+ released from surface-immobilized nAg diminishes over time and becomes less effective in suppressing biofilm formation of Gram-positive bacteria, such as S. aureus. This advocates the coating, more as a protection against perioperative and early postoperative infections, and less as a long-term preventive solution.

Abstract
PURPOSE To present a novel case of ocular argyrosis mimicking conjunctival melanoma. METHODS A 48-year-old man who is a jewelry manufacturer presented with raised pigmented lesions in the inferior fornices of both eyes. Brown-black colored, follicle-like, masses were observed in both fornices. RESULTS An incisional biopsy confirmed the presence of silver and the diagnosis of ocular argyrosis. CONCLUSIONS Despite its limited negative health effects, ocular argyrosis should be considered in the differential diagnosis of conjunctival pigmented lesions because of the potential for misidentification of neoplastic growth.

Abstract
SIGNIFICANCE This report details the natural history of corneal argyrosis over 3 years using in vivo confocal microscopy to document regression of hyperreflective deposits, as well as effects on corneal nerves and endothelial cell morphology. PURPOSE To report the in vivo confocal microscopic features and clinical characteristics of a case of bilateral corneal argyrosis. CASE REPORT A 52-year-old man referred to us 3 months following cautery of the palpebral conjunctiva of both eyes with a silver nitrate stick was observed over the course of 3 years, during which slit-lamp photography and in vivo confocal microscopy were performed. At the first visit, slit-lamp examination showed a light blue-green discoloration and a thick, yellow, oval discoloration in the right and left cornea, respectively. One year later, under slit-lamp examination, the right cornea appeared nearly transparent, and the discoloration in the left cornea had remarkably regressed. In vivo confocal microscopy done at that time showed highly reflective deposits in Descemet membrane of the right cornea and throughout Bowman layer, the stroma, and Descemet membrane of the left cornea. Three years later, no accumulation of silver was observed during slit-lamp examination of either eye. In vivo confocal microscopy of the right cornea did not reveal any silver deposits, and the corneal structure appeared normal. In the left cornea, some silver deposits were still evident in Descemet membrane, and alterations of corneal nerve and endothelial cell morphology were also evident. CONCLUSIONS This report reviews the 3-year natural history of a patient with corneal argyrosis. In vivo confocal microscopy demonstrates that over time the corneal argyrosis gradually resolves without any treatment. However, the presence of silver in the cornea may impact the corneal nerves and endothelial cells.

Abstract
Purpose The aim of this report is to present a case of a patient, metal foundry worker, who had been exposed to industrial silver salts for over 20 years. It is well established that chronic exposure to silver compounds can cause accumulation of silver deposits in various tissues. This condition is referred to as argyrosis or argyria, whereas changes related to eye tissues are defined as ocular argyrosis. Methods A complete eye examination, corneal confocal microscopy, kinetic and static visual field test, posterior segment optical coherent tomography, pattern visual evoked potentials (PVEP), flash visual evoked potentials, multifocal electroretinogram, pattern electroretinogram (PERG), full-field electroretinography (FERG) and electrooculogram were all performed. Results Eye examination revealed decreased visual acuity, corneal deposits and drusenoid changes within the macula. Although electrophysiology tests did not show changes in the function of retinal pigment epithelium, they revealed abnormal function of photoreceptors in the central and peripheral retina. PERG abnormalities and delayed latency of P100 wave in PVEP confirmed impaired function of the inner layers of the retina in the macular region. Conclusions Corneal confocal microscopy and electrophysiological tests may help confirm the diagnosis of ocular argyrosis.

Abstract
This case report describes the clinical, autofluorescence, and optical coherent tomography findings in a patient with panocular argyrosis secondary to chronic intake of diluted silver nitrate salts in his water supply. An 86-year-old Caucasian male with a distinctive gray-bluish hue of the skin presented to our clinic, having developed a slow decrease in visual acuity in both eyes and nyctalopia for the past 2 years. Based on the patient’s history of chronic intake of silver nitrate salts and a positive skin biopsy (performed by the dermatology department, data not shown), a diagnosis of panocular argyrosis was made. Fluorescein angiography showed choroidal blockage with a completely dark choroid. Fundus autofluorescence was within normal limits. Optical coherent tomography showed multiple excrescences of retinal pigment epithelium in both eyes. Although the drusen-like changes on fundus examination and retinal pigment epithelium changes may account for the diminished vision, the presence of concomitant nyctalopia suggests underlying damage of the photoreceptors.

Abstract
Silver is used widely in wound dressings and medical devices as a broad-spectrum antibiotic. Metallic silver and most inorganic silver compounds ionise in moisture, body fluids, and secretions to release biologically active Ag(+). The ion is absorbed into the systemic circulation from the diet and drinking water, by inhalation and through intraparenteral administration. Percutaneous absorption of Ag(+) through intact or damaged skin is low. Ag(+) binds strongly to metallothionein, albumins, and macroglobulins and is metabolised to all tissues other than the brain and the central nervous system. Silver sulphide or silver selenide precipitates, bound lysosomally in soft tissues, are inert and not associated with an irreversible toxic change. Argyria and argyrosis are the principle effects associated with heavy deposition of insoluble silver precipitates in the dermis and cornea/conjunctiva. Whilst these changes may be profoundly disfiguring and persistent, they are not associated with pathological damage in any tissue. The present paper discusses the mechanisms of absorption and metabolism of silver in the human body, presumed mechanisms of argyria and argyrosis, and the elimination of silver-protein complexes in the bile and urine. Minimum blood silver levels consistent with early signs of argyria or argyrosis are not known. Silver allergy does occur but the extent of the problem is not known. Reference values for silver exposure are discussed.

Abstract
PURPOSE To identify the presence of silver deposits in the cornea using a new-generation confocal microscopy technique. METHODS Case report. RESULTS A 70-year-old man, who had been a jeweler for many years, was referred to our center for assessment of corneal opacity and ocular pigmentation. Slit-lamp examination revealed grayish, dense confluent deposits in the central and peripheral cornea, deep stroma, and Descemet's membrane. On confocal microscopy, we observed typical images of hyperreflective keratocytes across the entire stromal surface and two hyperreflective plaques coinciding with areas of metal deposition, one at Descemet's membrane and the other at Bowman's membrane. This last deposition site has not been previously identified in vivo by confocal microscopy. CONCLUSIONS Confocal microscopy is a useful tool for the diagnosis of corneal argyrosis because it allows the in vivo visualization of silver deposits at different corneal levels.

Abstract
Lesions of the caruncle are uncommon. On account of the histological composition of the caruncle, which includes, in addition to conjunctiva, hair follicles, sebaceous glands, sweat glands, and accessory lacrimal tissue, the caruncle may develop lesions that may be similar to those found in the skin, conjunctiva, or lacrimal gland. Clinical preoperative diagnosis is very difficult and reached only in about half of the cases. The vast majority of lesions of the caruncle are benign, mainly nevi. Reported malignant lesions are very rare but can be potentially fatal. Although malignancy is clinically overestimated, any suspected malignant lesion should be excised and examined histopathologically by an experienced pathologist. This study presents the clinical and histological data of 42 consecutive caruncular lesions processed at our laboratory and reviews previously reported cases of caruncular lesions.

Abstract
Cosmetic products and procedures can produce adverse effects on the ocular surface, ranging from mild discomfort to vision-threatening conditions. Complications of skin and eye products can be related to allergy or toxicity, often attributable to perfumes. Complications of blepharoplasty may be associated with overcorrection, scarring, or uneven contour of the lid margins, conditions that can cause significant ocular surface disease until they are corrected. Ocular surface effects of botulinum toxin injection include dry eye syndromes and also epiphora. More serious complications occur (rarely) and are dose- and location-related. Adverse effects of micropigmentation procedures involve pathological processes or, simply, poor cosmetic results. In certain youth cultures, special-effect contact lenses and even decorative conjunctival implants have gained popularity, presenting a wide variety of dangers, often attributable to poor education about care and hygiene.
