Ans:D. Any of the above.
The patient is suffering from Trichiasis
- It is an acquired condition characterised by posterior misdirection of previously normal eye lashes.
- Trichiasis is differentiated from pseudotrichiasis which occurs secondary to entropion (inward turning of eyelid). Both these conditions lead to irritation of cornea and may lead to punctate epitheliopathy. Trichiasis may lead to infectious keratitis, pannus formation or even corneal ulceration.
- Irritation of eyes ,Foreign body sensation in eye,Redness of eyes,Watering,Pain in eyes,Increased sensitivity to light,etc.
- Infectious :Trachoma,herpes Zoster
- Autoimmune:Ocular cicatricial pemphigoid.
- Stevens-Johnson syndrome,Vernal keratoconjunctivitis,Chronic staphylococcal blepharitis.
- Chemical:Alkali Burns
- Repair of orbital floor fracture,Blepharoplasty (eyelid surgery) , Repair of ectropion
Thermal burns to the lids
Management of Trichiasis is primarily surgical
- Epilation: Epilation involves mechanical removal of eyelashes with forceps.
- Electrolysis: Eyelash follicle is destroyed by passage of electric current through a fine needle inserted into lash root.
- Cryotherapy: Cryoprobe freezes the lash follicles and destroys it. It should be avoided in cases with ocular cicatricial pemphigoid.
- Laser thermoablation: Laser thermoablation may be used to destroy eyelash follicles.
- Radiofrequency ablation: Smallest gauge wire is introduced alongside the lash to the follicle for destruction with radiofrequency.
