Pseudoexfoliation Syndrome (PEX)? glaucoma, pupil cataract, true foliation 👁 What is Pseudoexfoliation Syndrome (PEX)?PEX is a systemic ocular condition in which abnormal fibrillar protein deposits accumulate on the lens, iris, cornea, and other ocular structuresFirst described by Lindberg in 1917Best observed after pupillary dilationPredominantly affects elderly patients, more common in females🔍 True vs Pseudo ExfoliationTypeDescriptionTrue exfoliationCapsular delam.. 2025. 4. 20. Aniridia, WAGR syndrome, nystagmus, glaucoma, strabismus 👁 What is Aniridia?Aniridia is a rare congenital eye disorder characterized by the partial or complete absence of the iris.While the iris controls how much light enters the eye, aniridia affects not only the iris but also multiple ocular structures, making it a panocular disease.🔬 Key Ocular FeaturesFeatureDescriptionPhotophobiaIris absence leads to light sensitivityVisual delayDue to corneal .. 2025. 4. 20. Sturge-Weber Syndrome (SWS), phakomatosis, Choroidal hemangioma & Glaucoma 👁 What is Sturge-Weber Syndrome (SWS)?Sturge-Weber Syndrome is a type of phakomatosis,characterized by vascular malformations involving the brain, face, and eyes.Also called Encephalotrigeminal angiomatosis📊 Incidence: ~1 in 50,000 live births🧠 The Triad of AngiomasIntracranial AngiomaTypically in occipital / parieto-occipital lobesCommon symptoms:Seizures (75–90%)Intellectual disability (50%.. 2025. 4. 20. 👁 Intraocular Pressure (IOP) & Glaucoma: Why It Matters, Tonometers for IOP Measurement 👁 Intraocular Pressure (IOP) & Glaucoma: Why It MattersGlaucoma causes irreversible optic nerve damageIOP measurement is the key tool for early detection and managementPlays a role in diagnosis, monitoring, and screening🧪 Key Tonometers for IOP Measurement1.
