Trosolwyg
Trosolwg ymchwil
Mae fy niddordebau yn cynnwys ymchwil glinigol ac iechyd cyhoeddus. Mae'r prosiectau presennol yn cynnwys yr ymchwiliad i ddarparu gwasanaethau iechyd a chymdeithasol i unigolion â nam ar eu golwg, gwerthuso cyflyrau llygaid acíwt mewn gofal sylfaenol ac eilaidd, diogelwch cleifion sy'n ymwneud â gofal llygaid a rôl poen sy'n gysylltiedig â thrin dirywiad macwlaidd sy'n gysylltiedig ag oedran (AMD). Mae prosiectau diweddar wedi archwilio canlyniadau adsefydlu golwg. Arall penodol Mae meysydd yn cynnwys mesurau o swyddogaeth weledol mewn anhwylderau system weledol. Yn benodol, mae gennyf ddiddordeb mewn monitro dilyniant colled weledol, gan ddefnyddio technegau swyddogaethol a delweddu. Mae astudiaethau diweddar wedi gwerthuso'r defnydd o ficroberimetreg mewn AMD ac mewn clefydau eraill, gan ganolbwyntio ar ddehongli clinigol mewn perthynas â data normadol. Mae gwaith blaenorol hefyd yn cynnwys asesu'r berthynas rhwng ansawdd bywyd sy'n gysylltiedig â gweledigaeth gyda chanlyniadau bywyd gyda chanlyniadau bywyd mesurau clinigol fel microperimetreg, yn AMD ac ymchwiliad i mewn i ymylon wrth gefn yn nystagmus.
Trosolwg addysgu
Mae fy nyletswyddau addysgu yn cynnwys rôl arweinydd modiwl ar gyfer y modiwl "Ffarmacoleg Ocwlaidd" ar gyfer myfyrwyr israddedig ail flwyddyn. Rwy'n gyfrifol am drefnu'r cwrs, dylunio strwythur y cwrs ac ysgrifennu a chyflwyno'r darlithoedd a'r sesiynau ymarferol.
Derbyniadau
Fel Cyfarwyddwr Recriwtio a Derbyn, rwy'n gyfrifol am reoli'r prosesau derbyn israddedig yn yr Ysgol.

Ymchwil
Mae gen i awydd cryf i ymgymryd ag ymchwil sy'n cael effaith uniongyrchol ar gymdeithas. Rwy'n ymwneud â nifer o brosiectau ym maes iechyd y cyhoedd ac mewn prosiectau clinigol sy'n gysylltiedig â chlefydau retinol, megis dirywiad macwlaidd sy'n gysylltiedig ag oedran (AMD). Rwy'n aelod o'r Grŵp Iechyd Cyhoeddus Offthalmig a'r Grŵp Ymchwil Macwlaidd.
Prosiect gofal llygaid acíwt
Mae'r prosiect hwn yn gydweithrediad amlddisgyblaethol gyda'r Athro Barbara Ryan, yr Athro Rachel North, Dr Angharad Hobby, Dr Andrew Carson-Stevens o'r Ysgol Meddygaeth, Dr Mat Smith o'r Ysgol Fferylliaeth, a Dr Nik Sheen o AaGIC, ac mae'n cael ei ariannu'n fewnol. Rydym yn ymchwilio i'r amodau llygaid acíwt sy'n cyflwyno i optometryddion, fferyllwyr, meddygon teulu ac i adrannau damweiniau ac achosion brys. Mae'r prosiect hefyd yn rhan o gydweithrediad â SAIL (Secure Anonymised Information Linkage), lle rydym yn cynnal dadansoddiad data ledled Cymru o ragnodi ar gyfer cyflyrau llygaid acíwt. I gael rhagor o fanylion ac i gymryd rhan yn yr astudiaeth fel cyfranogwr, dilynwch y ddolen hon.
Gwerthuso gwallau wrth ddarparu gofal i gleifion â phroblemau sy'n gysylltiedig â'r llygad
Wedi'i ariannu gan KESS2 East, cyd-oruchwyliwr yr Efrydiaeth PhD hon yw Dr Andrew Carson-Stevens a'r partner diwydiannol yw Optometreg Cymru. Nod y prosiect hwn yw gwerthuso diogelwch cleifion sy'n gysylltiedig â'r llygad. Y prif becynnau gwaith yn y prosiect yw: Datblygu a phrofi system adrodd digwyddiadau diogelwch cleifion ar gyfer optometreg yng Nghymru; Dadansoddiad dulliau cymysg o adroddiadau digwyddiadau diogelwch cleifion sy'n disgrifio gofal llygaid anniogel yng Nghymru a Lloegr; Consensws rhanddeiliaid ar natur gofal llygaid anniogel y gellir ei osgoi.
Dull ataliol ar gyfer Mynediad at lwybr System gyfan Cynaliadwy ar gyfer pobl hŷn ag ataliad vISion (ASSIST)
Bydd y prosiect yn mynd i'r afael â'r angen am ofal a chymorth mwy cynaliadwy i bobl hŷn sydd â nam ar eu golwg i'w helpu i fyw bywydau hapusach a mwy boddhaus. Gall y broblem i lawer o bobl hŷn â nam ar eu golwg fod yn cael mynediad at y math cywir o gymorth ar gyfer eu hanghenion unigol a dod o hyd iddynt. Mae Presgripsiynu Cymdeithasol yn golygu "cysylltu pobl â chefnogaeth gymunedol i reoli eu hiechyd a'u lles yn well", lle gall gweithwyr proffesiynol (e.e. meddygon, optometryddion, gweithwyr cymdeithasol, swyddogion tai) gyfeirio pobl at wasanaethau a gweithgareddau cymunedol.
Nod y prosiect yw darganfod beth yw'r ddarpariaeth bresennol o ofal a chymorth i bobl hŷn â nam ar eu golwg, i ddatgelu bylchau mewn mynediad a nodi meysydd arfer gorau. Byddwn yn argymell sut y gellir gwneud gwelliannau i gefnogi'n well, gweithio cydgysylltiedig a ffyrdd mwy effeithlon o ddefnyddio adnoddau presennol. Bydd y prosiect yn cynnwys dulliau cymysg, gan ddefnyddio dull realaeth i glywed barn unigolion â nam ar eu golwg a'u gofalwyr, yn ogystal â staff a rhanddeiliaid eraill.
Ymchwilio i boen ac anghysur sy'n gysylltiedig â chwistrelliadau gwrth-VEGF
Gyda Dr Ashley Wood, a'i ariannu gan Sefydliad Ymchwil Abbeyfield, rydym yn defnyddio ymchwil dulliau cymysg i werthuso profiad poen mewn cleifion sy'n cael pigiadau gwrth-VEGF ar gyfer AMD, fel rhan o gydweithrediad â'r Athro Heather Waterman, yn yr Ysgol Gofal Iechyd.
Trawsnewid gwasanaethau gofal llygaid Cymru
Nod y prosiect hwn yw gwerthuso'r gwasanaethau gofal llygaid gwell a ddarperir gan optometryddion mewn gofal sylfaenol, gan ddefnyddio mesurau profiad a adroddir gan gleifion. Fe'i hariennir gan y cynllun Cyflymu, gyda chefnogaeth Swyddfa Cyllid Ewropeaidd Cymru (WEFO) a Chronfa Datblygu Rhanbarthol Ewrop (ERDF). Rydym yn cydweithio ar ddyfarniad ERDF o £103K, a chyfanswm gwerth y prosiect yw £1.3M. Mae dilysiad o'r mesurau profiad a adroddwyd gan gleifion yn cael ei wneud mewn cydweithrediad â Phrifysgol Abertawe. Gyda'r Athro Barbara Ryan , a Dr Angharad Hobby, rydym yn cydweithio â Bwrdd Iechyd Prifysgol Caerdydd a'r Fro, a'r tîm Accelerate.
Rhagnodi annibynnol mewn optometreg
Mewn cydweithrediad â'r Athro Molly Courtenay, Angela Whitaker ac ymchwilwyr o Brifysgol Swydd Bedford ac Ysgol Feddygol Bryste, gwnaethom astudiaeth ansoddol yn ddiweddar ar y ffactorau sy'n effeithio ar ragnodi gan optometryddion rhagnodol annibynnol, yn seiliedig ar y Fframwaith Parthau Damcaniaethol. Bydd gwaith parhaus mewn cydweithrediad â Dr Nik Sheen o AaGIC yn datblygu cefnogaeth ar gyfer rhagnodi annibynnol gan optometryddion.
Prosiectau eraill
Mae fy niddordebau ymchwil hefyd yn cynnwys archwilio swyddogaeth weledol yn AMD, a sefydlwyd yn ystod fy PhD ac a ddatblygwyd yn ystod cymrodoriaethau ymchwil ôl-ddoethurol rhyngwladol. Roedd gwaith blaenorol yn cynnwys asesiad topograffig y retina gan ddefnyddio delweddu amlfoddol mewn perthynas â swyddogaeth weledol a fesurir gan ficroberimetreg a thechnegau maes gweledol eraill mewn AMD ac mewn clefydau retinaidd eraill. Mae astudiaethau diweddar wedi gwerthuso cymhwyso data normadol mewn microperimetreg, gan ddefnyddio'r Asesiad Uniondeb Macwlaidd (Centervue; Ffigur 1) ac MP-1 (Nidek) offerynnau, i alluogi dehongliad cadarn o ganlyniadau yn y rhai ag anhwylderau system weledol. Astudiaeth barhaus arall yw gwerthuso perthynas microperimetreg ag offerynnau bywyd sy'n gysylltiedig â gweledigaeth ac sy'n gysylltiedig ag iechyd mewn unigolion ag AMD.
Mewn ymchwil arall, rydym wedi penderfynu ar y cytundeb rhwng optometryddion golwg isel ac offthalmolegwyr ymgynghorol yn y broses o ardystio ar gyfer nam ar eu golwg. Rydym hefyd wedi amcangyfrif effaith adfer golwg ar ganlyniadau ansawdd bywyd unigolion â golwg isel. Mae ein canfyddiadau'n darparu cefnogaeth ar gyfer effeithiolrwydd y gwasanaeth adfer golwg.
Delweddau
- Ffigur 1. Mae microberimetreg yn arwain at lygad iach.
- Ffigur 2. Mae microperimetreg yn arwain at AMD cynnar.
Crynodeb o'r canfyddiadau
- Dangosodd optometryddion golwg isel ac offthalmolegwyr ymgynghorol berfformiad cyfatebol wrth ardystio nam ar y golwg, wrth ddosbarthu achosion cryno ar gyfer ardystio.
- Mae adferiad gweledigaeth yn cael dylanwad cadarnhaol ar ansawdd bywyd sy'n gysylltiedig â gweledigaeth.
- Yn AMD cynnar, teneuo'r haen segment allanol, a fesurir gan ddefnyddio segmentu haen retinol o ddelweddau tomograffeg cydlyniant optegol parth sbectrwm, yn gysylltiedig yn sylweddol â sensitifrwydd microperimetreg llai (Ffig 1.).
- Mae microberimetreg fasnachol wedi'i gyfyngu gan ddiffyg dadansoddiadau tebygolrwydd cadarn. Datblygwyd cronfa ddata normadol a model dadansoddi cadarn i ganfod annormaledd.
- Er gwaethaf tebygrwydd mewn gweithdrefnau ysgogiadau a throthwy rhwng microperimetreg ac ymylon confensiynol, mae gwahaniaethau pwysig rhwng offerynnau y mae angen eu hystyried wrth ddehongli canlyniadau meysydd gweledol. Mae'r rhain yn cynnwys y gwahaniaeth mewn ystod ddeinamig, data normadol a lefelau ymoleuedd cefndir. Roedd faint o golled weledol a ganfyddwyd, yn wahanol rhwng offerynnau ac roedd hyn yn dibynnu ar lefel addasu a math o glefyd retinol.
