Mae fy ymchwil yn canolbwyntio ar glefyd macwlaidd, prif achos nam ar y golwg yn y DU. Drwy ddatblygu technolegau newydd sy'n gallu canfod a monitro clefyd macwlaidd yn gynnar, rwy'n gobeithio y gallwn gyflymu datblygiad ymyriadau therapiwtig newydd.
Mewn partneriaeth â Chanolfan Dechnoleg Seryddiaeth y DU , mae ein tîm ymchwil, y Grŵp Ymchwil Macwlaidd, wedi datblygu techneg newydd o'r enw Densitometreg Retinol Delweddu ffyddlondeb uchel (IRD) sy'n archwilio uniondeb swyddogaethol y cyfadeilad retinol allanol. Bydd y ddyfais unigryw hon yn sicrhau newid paradeim yn ein dealltwriaeth o swyddogaeth retinaidd mewn iechyd a chlefydau. Ynghyd â thechnolegau mwy confensiynol rydym ar hyn o bryd yn defnyddio IRD mewn treial clinigol o gyfansoddyn therapiwtig newydd ar gyfer dirywiad macwlaidd sy'n gysylltiedig ag oedran.

Ymchwil
Datblygu technolegau diagnostig newydd a therapiwteg ar gyfer clefyd macwlaidd cam cynnar yw fy mhrif ddiddordeb ymchwil. Ynghyd â chydweithwyr yn ein Grŵp Ymchwil Macwlaidd, rwy'n cymryd rhan yn y prosiectau canlynol:
SAponins for MAcular DIsease (SAMADI)
Gyda Dr Ashley Wood, yr Athro Marcela Votruba, Dr Rebecca Playle, Ms Claire Nollett, Dr Irene Ctori a Dr Alison Binns, mae hwn yn Dreial Clinigol o Gynnyrch Meddyginiaethol Ymchwiliol (saponinau triterpenoid) ar gyfer dirywiad macwlaidd sy'n gysylltiedig ag oedran cynnar a chanolradd. Ariennir y treial Cam II hwn gan AltRegen Co. Ltd, a gydlynir gan y Ganolfan Treialon Reseach ac mae'n cael ei gynnal ym Mhrifysgol Caerdydd a Phrifysgol y Ddinas, Llundain. Mae'r broses recriwtio yn agor ym mis Hydref 2021. Mae metrigau addasu tywyll, gan gynnwys y rhai o Densitometreg Retinol Delweddu ffyddlondeb uchel (IRD), yn fesurau canlyniadau.
Densitometreg delweddu ffyddlondeb uchel: archwilio'r berthynas rhwng cinetegau pigment gweledol, fasgwlature choroidal a dyddodion dedrusenoid is-retinol mewn dirywiad macwlaidd sy'n gysylltiedig ag oedran
Gyda Dr Ashley Wood mae'r efrydiaeth PhD hon (Ms Vera Silva) a ariennir gan y Gymdeithas Macwlaidd yn anelu at sefydlu: 1) effaith oedran ar ganlyniadau IRD ac OCTA; 2) y berthynas rhwng swyddogaeth allanol-retinol a vasculature choroidal mewn pobl ag AMD cam cynnar; 3) y berthynas rhwng IRD a mesurau confensiynol o addasu tywyll a chleifion adroddwyd swyddogaeth weledol.
Delweddu swyddogaethol o'r retina allanol gan ddefnyddio densitometreg delweddu ffyddlondeb uchel: archwilio'r berthynas rhwng cineteg pigment gweledol a phatholeg AMD
Gyda Dr Ashley Wood bydd yr efrydiaeth PhD a ariennir gan Goleg yr Optometryddion (Ms Krishna Pattni) yn defnyddio IRD i ddarganfod sut mae nodweddion drusen, gan gynnwys ffug-drusen reticular, yn effeithio ar adfywio pigmentau gweledol. Byddwn yn profi'r rhagdybiaeth bod adfywio pigmentau côn yn cael ei amharu'n ddetholus gan ddrusen meddal ac adfywio pigmentau gwialen gan ffug-ddrusen reticular.
Defnyddio Realiti Estynedig (AR) i wella symudedd mewn pobl â golwg isel
Gyda Dr Parisa Eslambolchilar a'r Athro Yukun Lai o'r Ysgol Cyfrifiadureg a chymorth gan Guide Dogs, Sefydliad y Deillion Caerdydd (CIB) a Sight Cymru, mae'r efrydiaeth PhD hon (Hein Htike) yn datblygu dyfais realiti estynedig a all helpu pobl sydd â golwg isel i lywio'u ffordd o amgylch adeiladau a'r amgylchedd adeiledig yn ddiogel.
