Dr Park is an BrisbaneEye Doctor who performs diagnosis and treatment of many eye conditions such as cataracts, macular degeneration, macular holes, epiretinal membranes, retinal detachment, diabetes (diabetic retinopathy), retinal vein occlusions, glaucoma.
A cataract is a clouding of the natural lens of the eye. This can result in reduced vision that can affect driving, reading and general day to day activities, result in glare sensitivity, and a sense of just not seeing clearly. It can be compared to looking through a smudgy windscreen. Cataracts are part of the aging process. By the age of 60 half of all people will have some cataract although it may be mild. Medical conditions such as diabetes, injury, chronic eye diseases can also result is cataracts, and rarely some people are born with cataracts. Treatment of cataract involves surgery. Cataract surgery is performed under monitored local anaesthetic at a Day Surgery Hospital. Cataract surgery is a successful procedure in 98% of cases. Dr Park will discuss your suitability for cataract surgery.
Macular Degeneration (AMD)
Macular degeneration also known as Age related macular degeneration (AMD) is a degenerative condition affecting the central area of the retina called the macula. There are two types of AMD, dry and wet. Dry AMD is more common and can cause slow progressive loss of vision. Wet AMD is characterized by the development of abnormal blood vessels beneath the retina which may leak fluid and/ or bleed. Vision loss can occur quickly. Intravitreal injections (injection of medication into the eye) Anti-VEGF is required for treatment of wet AMD. PBS approved meditations are used at Mt Ommaney. Injections are performed at Westside Eye Clinic. It is important to monitor vision with amsler grids as early treatment of wet AMD offers best vision outcome. Studies have demonstrated benefit in taking anti-oxidants, supplements (e.g. Macuvision plus) & cessation of smoking to reduce the risk of progression of Age related macular degeneration.
Macular Surgery (Vitrectomy microsurgery)
Macular hole is a defect/ a hole that occurs in the central area of retina called the macular. Vitrectomy surgery is required to treat macular hole.
Epiretinal membrane (Macular pucker, cellophane maculopathy) causes 'wrinkling' of central area of retina called the macular. If this causes symptoms (such as distortion) and/ or swelling of macular, vitrectomy surgery is usually required.
Retinal detachment occurs when retina ('the wall paper of eye') peels off the back wall of the eye. It usually occurs as a result of vitreous contraction in an aging eye which causes retinal traction and may result in a retinal tear. In most cases the vitreous contracts and does not cause retinal problems, this is known as a posterior vitreous detachment and results in floaters in the eye. Retinal detachment can result in rapid vision loss. Often one will experience a dark 'curtain' or a 'shadow' moving across the vision (so called field defect). Retinal detachments require surgery and Dr Park will discuss with you the best treatment option.
Posterior Vitreous Detachment (PVD)
Inside the eye is filled with a jelly like substance called vitreous. Vitreous ('the jelly') is made up of collagen and water. With aging, the vitreous becomes more watery and loses its shape and consistency, and pulls away from the back of the eye. This is called posterior vitreous detachment (PVD). This is different to retinal detachment. Over 75% of those over the age of 65 develop a PVD. Symptoms include floaters (like cobwebs) and flashes of light. It is unusual for PVD to cause long term visual problems. PVD can be associated with retinal tears and it is important to have retinal examination following an onset of a PVD to exclude retinal tears.
Diabetic Retinopathy (Diabetic Eye Disease)
Diabetic Retinopathy is an eye disease caused by complications of diabetes mellitus. Diabetes in the eye causes damage to the small blood vessels that nourish the retina (light sensitive film at the back of the eye). These blood vessels may expand and leak fluid. Fluid that leaks at the macula (central retina) can cause macular oedema (macular swelling) which can result in vision loss. Diabetic retinopathy can be severe with growth of abnormal new blood vessels, which can bleed and cause vitreous haemorrhage (bleeding in the jelly of the eye). Treatment can include intravitreal injections (injection of Eye medication into eye), laser, and in more severe cases vitrectomy surgery. Eye Injections are performed at Westside Eye Clinic. It is important to control blood sugar, blood pressure and cholesterol levels to reduce diabetic damage to the eye. Taking a tablet may help reduce diabetes in the eye, please ask Dr Park.
