Areas of Expertise
Retinal Disease
Dr O'Regan's primary focus is medical retina. He diagnoses and treats conditions including macular degeneration (AMD), diabetic eye disease, retinal vein occlusions, and other disorders of the retina and macula. He performs intravitreal injections (anti-VEGF and steroid therapies) and specialist retinal laser treatments, supported by advanced retinal imaging for precise diagnosis and ongoing monitoring.
Glaucoma
Dr O'Regan provides medical glaucoma care for patients with raised eye pressure and glaucoma. He also offers Selective Laser Trabeculoplasty (SLT) — an effective, minimally invasive laser treatment that lowers eye pressure and can reduce or eliminate the need for long-term eye drops.
General Ophthalmology
Dr O'Regan also sees patients with general eye conditions, including dry eye, blepharitis, watery or red eyes, and minor eyelid problems such as styes and eyelid cysts.
