A scleral buckle is one of several ophthalmologic procedures that can be used to repair a retinal detachment. Retinal detachments are usually caused by retinal tears, and a scleral buckle can be used to close the retinal break, both for acute and chronic retinal detachments. [citation needed] Scleral buckles come in many shapes and sizes.
Retinal detachment is a condition where the retina pulls away from the tissue underneath it. [1] [2] [3] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. [4] Retinal detachment is a medical emergency that requires surgery. [2] [3]
A retinal implant is a visual prosthesis for restoration of sight to patients blinded by retinal degeneration. The system is meant to partially restore useful vision to those who have lost their photoreceptors due to retinal diseases such as retinitis pigmentosa (RP) or age-related macular degeneration (AMD).
Surgically correct retinal detachment by scleral buckle or pars plana vitrectomy. [1] Prior to surgery, oral or topical anti glaucoma drugs may be used to reduce IOP. [1] After surgical correction of the retinal detachment, the condition resolves, aqueous cells disappear and IOP normalizes. [3] The condition is not responsive to corticosteroid ...
A blurred or gray spot in the central visual field is common when the retina is detached. Reduced visual acuity may persist after the fluid has disappeared. [1] The disease is considered of unknown cause. It mostly affects white males in the age group 20 to 50 (male:female ratio 6:1) [3] and occasionally other groups.
This is referred to as an "exoplant". Placement of the scleral buckle for patients who have had a retinal detachment has been shown to lead to reattachment approximately 80 to 90 percent of the time after one surgery. In cases of failure, most patients are treated with vitrectomy.
Nearly all ocular surgeries viz keratoplasty, cataract extraction, glaucoma surgery, iridectomy, strabismus, [5] retinal detachment surgery etc. can be done under regional anaesthesia. Conjunctiva, globe and orbicularis can be paralysed using a combination of surface anaesthesia, facial anaesthesia and retrobulbar block. [1]
Argus retinal prosthesis, also known as a bionic eye, is an electronic retinal implant manufactured by the American company Second Sight Medical Products. It is used as a visual prosthesis to improve the vision of people with severe cases of retinitis pigmentosa .
