Disease&Treatment50 Argentina Flag Sign? CCC Continuous Curvilinear Capsulorrhexis complication cataract surgery 👁 What is CCC (Continuous Curvilinear Capsulorrhexis)?Introduced by Gimbel and Neuhann in 1984A key step in cataract surgeryCreates a smooth circular opening (5–5.5 mm) in the anterior lens capsulePrevents radial tears during phaco or IOL insertion🌀 What is the Argentina Flag Sign?A rapid bilateral radial tear of the anterior capsuleNamed for its resemblance to the Argentinian flagOften occurs.. 2025. 4. 19. CCC (Continuous Curvilinear Capsulorrhexis). 👁 What is CCC in Cataract Surgery?Modern cataract surgery primarily involvesphacoemulsification followed by posterior chamber intraocular lens (IOL) implantation.A critical step in this process isCCC (Continuous Curvilinear Capsulorrhexis).🧬 What is CCC?A smooth, round opening (~5–5.5 mm) is created in the anterior lens capsuleAllows safe access for phacoemulsification and IOL insertionEssenti.. 2025. 4. 19. Steroid-Induced Glaucoma (SIG)?, steroid induced IOP increase 👁 What is Steroid-Induced Glaucoma (SIG)?Steroid-induced glaucoma (SIG) is a form of secondary glaucomacaused by elevated intraocular pressure (IOP) after using steroids,whether topical, periocular, systemic, or injected.🔬 Mechanism of SIGSteroids alter trabecular meshwork structure↑ ECM (extracellular matrix) deposition↓ Phagocytic activity → waste builds up→ Outflow resistance increases → IO.. 2025. 4. 19. Toxic Cataract?, Steroid induced cataract, antipsychotics, anticancer, arrhythmia 👁 What is Toxic Cataract?A toxic cataract refers to a lens opacity induced by medications or chemical substances,used either topically (e.g., eye drops) or systemically (oral or injectable drugs). 🔬 Common Cataract-Inducing DrugsDrug TypeAgentCataract TypeSteroidsPrednisolonePosterior subcapsular (PSC)AntipsychoticsChlorpromazineAnterior subcapsular + corneal depositsAnticancerBusulfanPosteri.. 2025. 4. 19. 👁 Modern Cataract Surgery: Phacoemulsification & IOL Insertion, Corneal incision, CCC, capsular tear 👁 Modern Cataract Surgery: Phacoemulsification & IOL InsertionThe current standard method for cataract surgery isphacoemulsification followed by posterior chamber intraocular lens (IOL) implantation.Though femtosecond laser is occasionally used, ultrasound remains central to cataract removal. 🧬 Key Surgical Steps (Simplified)Corneal IncisionCreates an entry point for surgical toolsCCC (Contin.. 2025. 4. 19. Cataract Surgery & Lens Anatomy Explained, lens capsule, zonule 👁 Cataract Surgery & Lens Anatomy ExplainedModern cataract surgery typically uses phacoemulsification with intraocular lens (IOL) implantation,a method first introduced by Kelman in 1967.📌 Surgical Goal EvolutionTransitioned from restoring cloudy vision to achieving→ better refractive outcomes→ fewer surgical complicationsBut complications like posterior capsule rupture, iris prolapse, radial .. 2025. 4. 19. Cataracts: Causes and Antioxidant Eye Drops 👁 Cataracts: Causes and Antioxidant Eye DropsCataracts remain the leading cause of blindness worldwide,accounting for nearly 48% of all blindness cases.While surgery is well-established, pharmacological prevention or delay is still under-researched.🔍 Key Risk FactorsAging, diabetes, UV exposure, malnutrition, smoking, renal diseaseMost importantly: Oxidative Stress→ Free radicals damage lens p.. 2025. 4. 19. What is Spheroidal Degeneration of the Cornea (SDC)? What is Spheroidal Degeneration of the Cornea (SDC)?Spheroidal degeneration is a degenerative ocular condition characterized by the deposition of yellow-brown, globular proteinaceous material in the cornea and/or conjunctiva.The term “spheroidal” implies a nearly spherical but imperfectly round appearance.🔍 Alternate NamesClimatic Droplet Keratopathy (CDK)Bietti’s nodular degeneration, Fisherma.. 2025. 4. 19. Corneal Lipid Degeneration What is Corneal Lipid Degeneration?Corneal Lipid Degeneration refers to the accumulation of lipids (fats) in the cornea,which can lead to corneal opacities. It is classified into:Primary (idiopathic)Secondary (acquired) 🔹 Primary Lipid DegenerationExtremely rare; no identifiable underlying causeOccurs without corneal neovascularizationLipids deposit in both central and peripheral stromaBlood li.. 2025. 4. 18.
