Sequelae of Trachoma are all EXCEPT
(Ectropion) (66-Khurana 4th) (168-Parson 20th)SEQUELAE OF TRACHOMA1. Sequelae in the lids - may be trichiasis, entropion** tylosis (thickening of lid margin) ptosis, maderosis and ankloblepharon2. Conjunctival sequelae - include concretions, pseudocyst xerosis and symblepharon3. Corneal sequelae - may be corneal opacity, ectasia, corneal xerosis and total corneal pannus blinding sequelae4. Other sequelae - may be chronic dacrocystitis, and chronic dacroadenitis* Trachoma causes superficial corneal vascularization* Pinguecula - degenerative condition formation of yellowish white patch on the bulbar conunctiva near the limbus, commonly in persons exposed to strong sunlight, dust and wind (same etiology of the Trachoma)* It affect the nasal side first & then the temporal side* ECTROPION - out rolling or outward turning of the lid margin is called ectropionTypes1. Senile ectropion - commonest variety2. Cicatricial ectropion - thermal bum, chemical bums lacerating injuries and skin ulcers3. Paralytic ectropion-paralysis of seventh nerve - Bell's palsy, head injury and infections of the middle ear4. Mechanical ectropion - tumours, as in proptoses and marked chemosis of the conjunctiva5. Spastic ectropion - spasm of the orbicularisFindings in TRACHOMA* Conjunctival follicles* (commonly on upper tarsals conjunctiva and fornix)* Papillary hyperplasia *** Conjunctival scaring* Herbert's pit*** Pannus*** Comeal ulcer, opacity & scarring* Vision 2020 - The five major eye conditions focusing are* Cataract** Trachoma** Onchocerciasis * * ** Childhood blindness* Refractive error and low vision* Arlt's line - fine linear scar in the sulcus subtarsalis in Trachoma*** The SAFE (Surgery, Antibiotics, Face washing, Environmental improvement) strategy for control of Trachoma*** Most common systemic association of scleritis is - Rheumatoid arthritis*** Lamina cribrosa (sieve like perforation in the posterior part of sclera) is absent in Morning glory syndrome** Sclera is thinnest at -posterior to attachment to superior rectus**** Telecanthus is - increase in intercanthal distance with normal interpupillary distance* Recurrent chalazion should be subjected to histopathologic evaluation to exclude the possibility of sebaceous cell carcinoma*** The comeal transparency is maintained by - Endothelium
