An ocular prosthesis , artificial eye or glass eye is a type of craniofacial prosthesis that replaces an absent natural eye following an enucleation , evisceration , or orbital exenteration . The prosthesis fits over an orbital implant and under the eyelids . Though often referred to as a glass eye, the ocular prosthesis roughly takes the shape of a convex shell and is made of medical grade plastic acrylic . A few ocular prostheses today are made of cryolite glass. A variant of the ocular prosthesis is a very thin hard shell known as a scleral shell which can be worn over a damaged or eviscerated eye. Makers of ocular prosthetics are known as ocularists . An ocular prosthesis does not provide vision; this would be a visual prosthesis . Someone with an ocular prosthesis is altogether blind on the affected side and has monocular (one sided) vision .

But the center shifted again, this time to Germany because of their superior glass blowing techniques. Shortly following the introduction of the art of glass eye-making to the United States, German goods became unavailable because of World War II. As a result, the US instead made artificial eyes from acrylic plastic. Production of modern ocular prosthetics has expanded from simply using glass into many different types of materials. In

One solution to this problem has been demonstrated recently in a device based on an LCD which simulates the pupil size as a function of the ambient light. There are many different types of implants, classification ranging from shape (spherical vs egg (oval) shaped), stock vs custom, porous vs nonporous, specific chemical make-up, and the presence of a peg or motility post. The most basic simplification can be to divide implant types into two main groups: non-integrated (non-porous) and integrated (porous). Though there

Because direct mechanical coupling is thought to improve artificial eye motility, attempts have been made to develop so-called 'integrated implants' that are directly connected to the artificial eye. Historically, implants that directly attached to the prosthesis were unsuccessful because of chronic inflammation or infection arising from the exposed nonporous implant material. This led to

The muscles may be directly sutured to porous polyethylene implants either by passing the suture through the implant material or by using an implant with fabricated suture tunnels. Some surgeons also wrap porous polyethylene implants either to facilitate muscle attachment or to reduce the risk of implant exposure. A variety of wrapping materials have been used to cover porous implants, including polyglactin or polyglycolic acid mesh, heterologous tissue (bovine pericardium), homologous donor tissue (sclera, dermis), and autogenous tissue (fascia lata, temporalis fascia, posterior auricular muscle, rectus abdominis sheath). Fenestrations in

8103-412: The muscles to the covering material, a technique that seems to improve implant movement and reduce the incidence of implant migration. Porous implants may be saturated with antibiotic solution before insertion. Because the brittle nature of hydroxyapatite prevents direct suturing of the muscles to the implant, these implants are usually covered with some form of wrapping material. The muscles are attached to
8214-497: The narrower and longer posterior portion, allows for a more complete and natural replacement of the lost orbital volume. This shape reduces the risk of superior sulcus deformity and puts more volume within the muscle cone. Muscles can be placed at any location the surgeon desires with these implants. This is advantageous for cases of damaged or lost muscles after trauma, and the remaining muscles are transposed to improve postoperative motility. In anticipation of future peg placement there
8325-526: The nation. Since becoming King himself Vajiralongkorn has presided over and participated in the ceremony in his own right. In honour of his coronation the Rice Department released five new rice varieties/cultivars and the king has continued patronage of the royal rice varieties competition, the tradition of his ancestor Chulalongkorn . Vajiralongkorn has initiated education projects to improve children's access to quality learning and instill
8436-421: The ocular prosthesis. Enucleation implants are available in a variety of sizes that may be determined by using sizing implants or calculated by measuring globe volume or axial length of the contralateral eye. In the past, spherical nonporous implants were placed in the intraconal space and the extraocular muscles were either left unattached or were tied over the implant. Wrapping these implants allows attachment of
8547-400: The office of King Vajiralongkorn had asked for several changes to clauses related to royal power in the draft constitution, a rare intervention by a reigning Thai monarch. After the death of King Bhumibol, political activity was paused during a period of mourning that ended in 2017. In February 2019, in an unprecedented move, the King's elder sister, Ubol Ratana , announced her candidacy for
8658-436: The optic nerve. The vortex veins and posterior ciliary vessels may be cauterized before dividing the nerve and removing the eye. Alternatively, the optic nerve may be localized with a clamp before transection. Hemostasis is achieved with either cautery or digital pressure. The orbital implant is inserted at the time of enucleation. An appropriately sized implant should replace the volume of the globe and leave sufficient room for
8769-434: The original lens has been removed in the treatment of cataracts and has historically been used as hard contact lenses. PMMA has a good degree of compatibility with human tissue, much more so than glass. Although various materials have been used to make nonintegrated implants in the past, polymethyl methacrylate is one of the implants of choice. The porous nature of integrated implants allows fibrovascular ingrowth throughout
8880-563: The piano and became fluent in English and French. Because of her father's work as a diplomat, the family moved to other countries, including Denmark and France. While in France, she studied at a music academy in Paris. Also in France, Sirikit met King Bhumibol Adulyadej , who was related to her, since both were descendants of King Chulalongkorn (Rama V). At that time, Bhumibol had ascended to
8991-424: The posterior surface of the artificial eye. This peg thus directly transfers implant motility to the artificial eye. However, the motility peg is mounted in a minority of patients. This may partially be due to problems associated with peg placement, whereas hydroxyapatite implants are assumed to yield superior artificial eye motility even without the peg. Polyethylene also becomes vascularized, allowing placement of
9102-741: The prince enrolled at the Royal Military College, Duntroon in Canberra , Australia. His education at Duntroon was divided into two parts, military training by the Australian Army and a bachelor's degree course under the auspices of the University of New South Wales . He graduated in 1976 as a new lieutenant with a liberal arts degree. In 1982, he completed a second bachelor's degree in law, with second-class honors at Sukhothai Thammathirat Open University . Vajiralongkorn
9213-472: The procedure, a type of ocular prosthesis is always needed afterwards. The surgeon will insert a temporary prosthesis at the end of the surgery, known as a stock eye, and refer the patient to an ocularist , who is not a medical doctor, but board certified ocularist by the American Society of Ocularists. The process of making an ocular prosthesis, or a custom eye, will begin, usually six weeks after
9324-482: The prosthesis, and are prone to implant exposure. Age and size of the implant may also affect the motility, since in a study comparing patients with hydroxyapatite implants and patients with nonporous implants, the implant movement appeared to decrease with age in both groups. This study also demonstrated improved movement of larger implants irrespective of material. Enucleation and orbital implantation surgery follows these steps: Also under anesthesia: The surgery
9435-412: The quality of agricultural production. Mobile Agricultural Clinic teams can move quickly to various spots in need of help. It has worked steadily and is ready to provide technical services and transfer technology. With this project, farmers have been urged to be aware of agricultural development and new technology. In the later years of his father, Bhumibol Adulyadej's reign, Vajiralongkorn represented
9546-580: The rail lines, making travel unsafe. She therefore moved to Saint Francis Xavier Convent School , since it was near the palace. She studied at Saint Francis Xavier from her second primary year through the early secondary level. In 1946, with the war now over, her father moved to the United Kingdom as the ambassador to the Court of St James's , taking his family with him. Sirikit was then 13 and completed her secondary education. While in England she learned to play
9657-402: The risk of transmission of infection, inflammation, and rejection. A 2008 study showed that HA has a more rapid rate of fibrovascularization than MEDPOR, a high-density porous polyethylene implant manufactured from linear high-density polyethylene. Development in polymer chemistry has allowed introduction of newer biocompatible material such as porous polyethylene (PP) to be introduced into
9768-467: The sight in one eye. He subsequently wore an ocular prosthetic . While he was hospitalised in Lausanne, Sirikit visited him frequently. She met his mother, The Princess Mother Sangwan , who asked her to continue her studies nearby so that the king could get to know her better. Bhumibol selected a boarding school for her in Lausanne, Riante Rive. A quiet engagement in Lausanne followed on 19 July 1949, and
9879-400: The smooth surface is less abrasive and irritating than other materials used for similar purposes. Polyethylene also becomes vascularized, allowing placement of a titanium motility post that joins the implant to the prosthesis in the same way that the peg is used for hydroxyapatite implants. PP has been shown to have a good outcome, and in 2004, it was the most commonly used orbital implant in
9990-562: The surgical procedure, and it typically will take up to three visits before the final fitting of the prosthesis. In most cases, the patient will be fitted during the first visit, return for the hand-painting of the prosthesis, and finally come back for the final fitting. The methods used to fit, shape, and paint the prosthesis often vary to suit both ocularist and patient needs. Living with an ocular prosthesis requires care, but oftentimes patients who have had incurable eye disorders, such as micropthalmia , anophtalmia or retinoblastoma , achieve
10101-694: The throne and was studying in Switzerland . Bhumibol and Sirikit (as well as a few other students) were staying at the Royal Thai Embassy in Paris. Sirikit accompanied the king as he visited various tourist attractions, and they found that they had much in common. On 4 October 1948, while Bhumibol was driving a Fiat Topolino on the Geneva - Lausanne road, he collided into the rear of a braking truck 10 km outside of Lausanne. He injured his back and incurred cuts on his face that cost him most of
10212-443: The throne on the night of 1 December 2016. His coronation took place from 4–6 May 2019. The Thai government retroactively declared his reign to have begun on 13 October 2016, upon his father's death. Aged 64 at that time, Vajiralongkorn became the oldest Thai monarch to ascend to the throne. He is the wealthiest monarch in the world , with a net worth estimated to be between US$ 30 billion and US$ 70 billion . Vajiralongkorn
10323-523: The title 'Somdet Phra Nang Chao Sirikit Phra Borommarachininat' on his birthday, 5 December 1956. She became the second Siamese queen regent in Thai history. The first was Queen Saovabha Phongsri of Siam , who served as regent when her husband King Chulalongkorn travelled to Europe, and later became Queen Sri Patcharindra. At dawn on 21 July 2012, Queen Sirikit felt unsteady and staggered while exercising at Siriraj Hospital , where King Bhumibol Adulyadej resided. After performing magnetic resonance imaging ,
10434-400: The title of "Chao Khun Phra" or Royal Noble Consort, and the royal name of Sineenat Wongvajirapakdi, to Major General Niramon Ounprom ; the occasion marked the first official naming of a secondary consort for nearly a century. Three months later, on 21 October 2019, a palace order stripped Sineenat of her title and ranks, stating that she had been disrespectful to Queen Suthida and disloyal to
10545-473: The upper eyelid, deepening of the superior sulcus, backward tilt of the prothesis, and stretching of the lower eyelid after evisceration or enucleation. These problems are generally thought to be secondary to orbital volume deficiencies which is also addressed by MCOIs. The conical shape of the MCOI more closely matches the anatomic shape of the orbit than a spherical implant. The wider anterior portion, combined with
10656-500: The use of ocular prosthesis is that of a woman found in Shahr-I Sokhta , Iran dating back to 2900–2800 BC. It has a hemispherical form and a diameter of just over 2.5 cm (1 inch). It consists of very light material, probably bitumen paste. The surface of the artificial eye is covered with a thin layer of gold, engraved with a central circle (representing the iris) and gold lines patterned like sun rays. On both sides of
10767-513: The wedding, Mom Sujarinee (as she was now known) decamped to Britain with all her children, while Vajiralongkorn caused posters to be placed all around his palace accusing her of committing adultery with Anand Rotsamkhan, a 60-year-old air marshal. Later, the prince abducted the daughter and brought her back to Thailand to live with him. She was later elevated to the rank of princess, whilst Sujarinee and her sons were stripped of their diplomatic passports and royal titles. Sujarinee and her sons moved to
10878-420: The wrapping material are created at the insertion sites of the extraocular muscles, allowing the attached muscles to be in contact with the implant and improving implant vascularization. Drilling 1 mm holes into the implant at the muscle insertion sites is performed to facilitate vascularization of hydroxyapatite implants. Tenon's fascia is drawn over the implant and closed in one or two layers. The conjunctiva
10989-478: Was "widely loathed and feared" and "unpredictable to the point of eccentricity", while the online journal Asia Sentinel said that he was "regarded as erratic and virtually incapable of ruling"; the journal was blocked shortly thereafter. In a leaked diplomatic cable , senior Singaporean foreign ministry official Bilahari Kausikan said that Vajiralongkorn had a gambling habit partly funded by exiled former prime minister Thaksin Shinawatra. On 12 November 2009,
11100-466: Was Thai ambassador. They married in 1950, shortly before Bhumibol's coronation. Sirikit was appointed queen regent in 1956, when the king entered the Buddhist monkhood for a period of time. Sirikit has one son and three daughters with the king. Consort of the monarch who was, at the time the world's longest-reigning head of state , she was also the world's longest-serving queen consort. Sirikit suffered
11211-512: Was about 11 years old and soon became a capable rider. While studying in Thailand and abroad, he played several sports with friends, including football, rugby, and rowing. Vajiralongkorn also competed in sailing with King Bhumibol and sister Princess Ubolratana when they stayed at Klai Kangwon Palace in Hua Hin. In football, Vajiralongkorn first played as a forward and later became a center-back at Chitralada School, Millfield School in England, and
11322-399: Was approved by Health and Welfare, Canada, in February 2001. Aluminium oxide has previously been shown to be more biocompatible than HA in cell culture studies and has been suggested as the standard reference material when biocompatibility studies are required to investigate new products. The rate of exposure previously associated with the bioceramic implant (2%) was less than most reports on
11433-472: Was at one point the most commonly used orbital implant in the United States. The porous nature of this material allows fibrovascular ingrowth throughout the implant and permits insertion of a coupling device (PEG) with reduced risk of inflammation or infection associated with earlier types of exposed integrated implants. Hydroxyapatite is limited to preformed (stock) spheres (for enucleation) or granules (for building up defects). One main disadvantage of HA
11544-475: Was banned on 7 March 2019 by the Constitutional Court of Thailand for bringing a member of the royal family into politics and its political leaders were banned from politics for a decade. Vajiralongkorn has direct control over the royal household and palace security agencies . Vajiralongkorn's reign has been plagued by controversies unheard of during the reign of his predecessor. His image
11655-842: Was born on 28 July 1952 at 17:45 in the Amphorn Sathan Residential Hall of the Dusit Palace in Bangkok . When the crown prince was one year old, Somdet Phra Sangkharat Chao Kromma Luang Vajirananavongse, the 13th Supreme Patriarch of Thailand of the Rattanakosin Era , gave the child his first name at birth, Vajiralongkorn Boromchakrayadisorn Santatiwong Thewetthamrongsuboribal Abhikkunupakornmahitaladulyadej Bhumibolnaretwarangkun Kittisirisombunsawangwat Boromkhattiyarajakumarn. Vajiralongkorn began his education in 1956 when he entered kindergarten at
11766-413: Was expected to succeed to the throne of Thailand but asked for time to mourn before taking the throne. On the night of 1 December 2016, the fiftieth day after the death of Bhumibol, Regent Prem Tinsulanonda led the heads of the country's three branches of government to an audience with Vajiralongkorn to invite him to ascend to the throne as the tenth king of the Chakri dynasty . Vajiralongkorn accepted
11877-671: Was finally able to sue for divorce in the Family Court in January 1993. In the court proceedings, Vajiralongkorn accused Soamsawali of being completely at fault for the failed relationship. She was not able to refute the charges due to the prohibition against lèse majesté . The divorce was finalized in July 1993. When Vajiralongkorn was introduced to Yuvadhida Polpraserth, she was an aspiring actress. She became his steady companion and gave birth to his first son, Prince Juthavachara Mahidol, on 29 August 1979. He later had three more sons and
11988-665: Was later pardoned by the king. Nicolaides later stated that "it's entirely fiction from cover to cover". In August 2011, the German judicial authorities in Munich impounded a Boeing 737 aircraft, one of two belonging to Crown Prince Vajiralongkorn. Administrators seized the aircraft because of a 20-year-old Thai government debt owed to a now-defunct German construction corporation for the Don Mueang Tollway , that had risen to some €30 million. German authorities, representing
12099-647: Was officially divorced from Vajiralongkorn. On 1 May 2019, three days before his coronation, Vajiralongkorn married Suthida Tidjai, former acting commander of Royal Thai Aide-de-Camp Department. Suthida was therefore made the queen consort of King Vajiralongkorn whose coronation took place in Bangkok on 4–6 May 2019. The marriage registration took place at the Amphorn Sathan Residential Hall in Bangkok, with his sister Princess Sirindhorn and President of Privy Council Prem Tinsulanonda as witnesses. On 28 July 2019, Vajiralongkorn bestowed
12210-554: Was proclaimed crown prince on 28 December 1972 at 12:23 in the Ananta Samakhom Throne Hall , making him the third crown prince of the Chakri dynasty. On 6 November 1978, at age 26, the prince was ordained as a monk at Wat Phra Kaew . As is traditional for royals, he stayed at Wat Bowonniwet Vihara for 15 days, under the monastic name "Vajiralongkornno". After completing his studies, Vajiralongkorn served as
