Trosolwg ymchwil
Mae fy mhrif ddiddordebau ymchwil mewn seicoffiseg sylfaenol a chlinigol. Mae ymchwil yn fy labordy wedi'i anelu'n bennaf at gael gwell dealltwriaeth o bensaernïaeth swyddogaethol y system weledol iach a sut mae'n cael ei newid mewn anhwylderau niwroddirywiol fel glawcoma a dirywiad macwlaidd . Er mwyn mynd i'r afael â'r nodau hyn, mae fy labordy yn defnyddio cyfuniad o seicoffiseg, electroffisioleg, delweddu retinal, a fMRI. Rydym hefyd yn defnyddio'r ddealltwriaeth hon i lywio'r ddylunio offer clinigol cywir a manwl gywir ar gyfer nodi'r diffygion cynharaf o ganfyddiad gweledol yn yr anhwylderau hyn. Rwy'n Brif Ymchwilydd ar Astudiaeth REVAMP, astudiaeth aml-safle ledled y DU a ariennir gan Gynllun Cyllido Llwybr Datblygiadol (DPFS) y Cyngor Ymchwil Feddygol (MRC), lle rydym yn datblygu math newydd o brawf maes gweledol sy'n seiliedig ar dystiolaeth ar gyfer adnabod a monitro clefyd y llygaid, yn fwyaf arbennig glawcoma.
Trosolwg addysgu
Rwy'n arweinydd modiwl ar gyfer 'Cyflwyniad i Ymarfer Optometrig Clinigol' a hefyd yn addysgu ar y modiwlau 'Normal Eye and Visual Pathway', 'Visual Correction', 'Advanced Visual Correction', a 'The Eye'. Yn ogystal, rwy'n goruchwylio myfyrwyr israddedig blwyddyn olaf yn y modiwl Prosiect Ymchwil.

Er mwyn mynd i'r afael â'r nodau hyn, mae fy labordy yn defnyddio cyfuniad o seicoffiseg, electroffisioleg, delweddu retinal, a fMRI. Rydym hefyd yn defnyddio'r ddealltwriaeth hon i lywio'r ddylunio offer clinigol cywir a manwl gywir ar gyfer nodi'r diffygion cynharaf o ganfyddiad gweledol yn yr anhwylderau hyn.
Gwell mesuriadau o'r maes gweledol mewn glawcoma
Mae fy ymchwil wedi canolbwyntio ar nodweddu amrywioldeb signal ac ymateb clefyd gyda chyfluniadau ysgogiad amrywiol mewn cleifion â glawcoma, ac archwilio ffyrdd y gellir cynyddu'r gymhareb signal/sŵn i wella canfod colli golwg cynnil dros amser. Mae gen i ddiddordeb hefyd yn sut mae mesurau clinigol golwg yn cael eu heffeithio gan newidiadau nad ydynt yn niwral yn y llygad sy'n digwydd gydag oedran neu glefyd y llygaid (e.e. mwy o ysgafn intraocular, melyn lens crisialog).
Ymchwil a Gwerthuso Perimetreg Modiwleiddio Arwynebedd (astudiaeth REVAMP)
Yn ddiweddar, dyfarnwyd £1.82miliwn i'm tîm gan Gynllun Cyllido Llwybr Datblygiadol MRC (DPFS) ar gyfer ymchwil i ffyrdd gwell o adnabod colli maes gweledol mewn pobl â glawcoma. Mae'r gwaith hwn yn cael ei wneud mewn cydweithrediad â Dr Padraig Mulholland a'r Athro Roger S Anderson ym Mhrifysgol Ulster, yr Athro David F Garway-Heath yn Sefydliad Offthalmoleg UCL, a'r Athro James E Morgan ym Mhrifysgol Caerdydd. Gellir dod o hyd i ragor o fanylion, gan gynnwys sut i gymryd rhan yn yr astudiaeth, ar dudalen we REVAMP.
Diffygion canfyddiad gweledol gydag oedran a chlefyd
Rydym wedi ymchwilio i newidiadau mewn crynhoad gofodol gydag oedran ac mewn glawcoma cynnar. Dangosodd dau bapur gan ein grŵp, a gyhoeddwyd ochr yn ochr yn Investigative Ophthalmology and Visual Science , er bod crynhoad gofodol yn ddigyfnewid gydag oedran sy'n datblygu, gellir cyfrif am golli sensitifrwydd (i fan bach o olau sy'n amrywio mewn disgleirdeb) mewn glawcoma cynnar trwy ehangu'r ardal o grynhoi gofodol cyflawn (ardal Ricco). Mae gwaith mwy diweddar gan ein grŵp wedi dangos bod crynhoi amser hefyd yn cael ei newid mewn glawcoma. Gyda'i gilydd, mae gan y canfyddiadau hyn oblygiadau uniongyrchol ar gyfer dylunio profion clinigol cywir ar gyfer mesur diffygion maes gweledol cynnar mewn glawcoma.
Delweddu'r ymennydd
Rydym yn defnyddio fMRI a seicoffiseg i astudio ad-drefnu yn y cortecs gweledol dynol mewn glawcoma, gyda chydweithwyr yng Nghanolfan Delweddu Ymchwil yr Ymennydd Prifysgol Caerdydd (CUBRIC). Mae'r gwaith hwn yn cael ei ariannu'n hael gan Fight for Sight, yr Elusen Ymchwil Llygaid.
Delweddu côn in vivo
Rydym wedi bod yn ymgymryd â chyfres o arbrofion lle mae conau yn cael eu delweddu in vivo gan ddefnyddio offeryniaeth glinigol. Cyhoeddwyd canfyddiadau cychwynnol yn ddiweddar yn y cyfnodolyn Ophthalmology.
Aciwtedd gweledol
Mae profion aciwtedd gweledol clinigol yn gyflym ac yn syml i'w perfformio, ond gall y canlyniadau fod yn amrywiol iawn, gan eu gwneud yn eithaf ansensitif i newidiadau cynnil mewn golwg sy'n digwydd dros amser neu mewn ymateb i driniaeth. Un ffactor sy'n cyfrannu yw'r amrywiad eang mewn darllenadwyedd optoteip. Mewn un astudiaeth, fe wnaethom ddangos sut mae 'vanishing optotype acuity' (aciwtedd wedi'i fesur gydag optoteipiau ffug-uchel) yn fwy unffurf ar draws llythrennau nag aciwtedd i lythrennau confensiynol. Gellir gweld optoteipiau sy'n diflannu yn Ffigur 3.
