![]() However, optical coherence tomography (OCT) can provide unexpectedly good pictures through comparatively small pupils and moderately dense lens opacities. In people with advanced cataracts, tests such as ophthalmoscopy, fluorescein angiography, and fundus photography may be hampered to a great extent. Even though the potential acuity meter (PAM) is most often helpful, and several tests of reading performance could also give helpful information. It may be tough to distinguish between vision loss from retinal pathology and vision loss from cataract. Therefore, identifying associated retinal pathology is an important aspect of preoperative assessment as well as informed consent. Rather than any specific surgical complication, an unrecognised retinal disorder following cataract surgery may cause a disappointing visual outcome. General Principles and Preoperative Planning for Cataract Surgery in People with Retinal Diseases It is the second most common retinal vascular disorder after diabetic retinopathy. Retinal vein occlusion: A condition characterised by blockage of small veins that drain blood from the retina.Macular degeneration: This is the deterioration of the central portion of your retina which causes blurring of vision or blind spots.Macular hole: It is a small hole present in the centre of the retina.Epiretinal membrane: It is a thin layer of scar tissue that forms on the surface of the retina.Diabetic retinopathy: Diabetes can cause deterioration of the tiny capillaries in the eye resulting in leakage of fluid into the retina, retinal swelling, and vision distortion. ![]() Retinal detachment: This may occur when fluid passes through a retinal tear causing it to become detached from the underlying tissue.Retinal tears: A retinal tear may occur when the central gel-like substance of your eyeball shrinks and pulls on the retinal tissue lining the inner surface of the eyeball.Some of the common retinal diseases include: However, complications can be minimised, and visual outcomes improved by expecting issues and formulating a comprehensive preoperative, intraoperative, and postoperative plan. Hence, the decision to carry out cataract surgery in people with pre-existing retinal diseases is usually challenging and may increase the risk of complications for the patient. ![]() Ultimately, cataract surgery can result in retinal disease de novo, like cystoid macular oedema. Contrarily, cataract surgery may worsen existing retinal conditions, such as uveitis, macular degeneration, and diabetic retinopathy. Cataract formation can occur following pneumatic retinopexy and pars plana vitrectomy (PPV), surgical treatments for retinal detachment. ![]() Vision can be corrected with cataract surgery, which involves the removal of the cloudy lens and replacing it with an artificial intraocular lens (IOL) implant.Ĭataracts and retinal diseases are frequently associated with each other. Any structural change in these proteins can alter the clarity of the lens and negatively impact vision. These specific proteins provide the lens its transparent structure. The lens is mostly made up of water and proteins. People with high blood pressure, diabetes, high blood cholesterol levels, or other vascular diseases are more prone to retinal diseases.Ī cataract is a condition which causes clouding of the natural lens in the eye, resulting in blurry vision. It is composed of millions of specialised light-sensitive cells that are capable of receiving and organising visual information which is transmitted through the optic nerve to your brain allowing you to see. The retina is a thin layer of tissue present on the inner surface of the back of your eyeball. Retinal diseases are conditions or disorders that affect your retina causing visual symptoms such as blurred vision.
