👁 What is Limbal Girdle?Limbal girdle refers to a white, arc-shaped opacity seen at the peripheral cornea, near the limbus.It is a common, age-related degeneration, typically asymptomatic.🔍 Key FeaturesFound in 55% of people aged 40–60Seen in almost 100% of individuals over age 80Typically bilateral and symmetricMost common in the nasal and inferior limbus 🧬 Types of Vogt’s Limbal Girdle🟡 Ty..

👁 Corneal Degeneration vs. Corneal Dystrophy – What’s the Difference?When describing corneal changes, ophthalmologists distinguish between:DegenerationDystrophyEach term refers to different causes, patterns, and implications.🧬 🔍 DefinitionsAspectDegenerationDystrophyOnsetTypically in middle-aged or elderly individualsUsually before age 10CauseAcquired, age-related, environmentalGenetic, conge..

👁 What is Posterior Polymorphous Corneal Dystrophy (PPMD/PPCD)?Posterior Polymorphous Corneal Dystrophy (PPMD/PPCD) is a rare, autosomal dominantcorneal dystrophy in which corneal endothelial cells take on epithelial-like characteristics.🔍 Key FeaturesUsually asymptomatic, no significant pain or vision lossDoes not typically progress to stromal edema or severe corneal hazeIn rare cases, it may..

👁 What is Fuchs’ Endothelial Dystrophy?Fuchs' Endothelial Dystrophy (FED) is a progressive corneal disorderwhere corneal endothelial cells fail, leading to corneal swelling (edema) and gradual vision loss.It usually affects both eyes symmetrically and is more common in middle-aged women (40s–50s).The earliest sign is the appearance of guttata — droplet-shaped excrescences on Descemet’s membrane..

👁 What is Macular Corneal Dystrophy?Macular Corneal Dystrophy (MCD) is a rare inherited disordercharacterized by grayish, ill-defined stromal opacities that progressively involve the entire cornea, including the limbus.🔍 Key FeaturesOnset typically before age 10Begins in the superficial central stroma and spreads to the deep layers and peripheryAppears as gray-white nodular lesions with diffus..

👁 What is Gelatinous Drop-like Dystrophy (GDLD)?Gelatinous Drop-like Dystrophy (GDLD) is a rare inherited corneal dystrophycharacterized by the formation of gelatinous, cyst-like opacities on the corneal surface.🔍 Key FeaturesUsually appears in early childhood, with mulberry-like elevated lesions beneath the epitheliumCaused by amyloid protein deposition in the superficial stromaProgressive vi..

👁 What is Schnyder Crystalline Corneal Dystrophy (SCCD)?Schnyder Crystalline Corneal Dystrophy (SCCD) is a rare genetic disorderin which sparkling, needle-like cholesterol or lipid crystalsaccumulate in the central cornea, often creating a shimmering appearance.🔍 FeaturesAutosomal dominant inheritance, but sporadic cases can occurCrystals are composed of cholesterol or lipids,deposited in the ..

👁 What is Fleck Corneal Dystrophy (FCD)?Fleck Corneal Dystrophy (FCD) is a rare, inherited corneal conditionin which small, freckle-like grayish opacities appear throughout the corneal stroma.🧬 Key CharacteristicsOpacities are confined to the stroma, not affecting the epitheliumThey are scattered throughout all stromal layers, often asymmetricallyUsually bilateral, but can also appear unilater..

👁 What is Central Cloudy Dystrophy of Francois (CCDF)?Central Cloudy Dystrophy of Francois (CCDF) is a rare, inherited corneal conditionfirst described by the French ophthalmologist Francois, hence its name.It is characterized by irregular, crocodile shagreen–like opacities in the posterior central corneal stroma.🧬 Key CharacteristicsInherited in an autosomal dominant (AD) patternOften associa..
