2. 70 yr old male presented with h/o swelling in rt lower lid -2months Painless swelling,slowly increasing in size. No h/o trauma,no h/o discharge from the mass. H/o similar swelling at the same site noticed 1yr back which was treated by aspiration 3 months back
3. H/o DM-4yrs General examination and systemic examination wnl H/o cataract surgery in BE. BCVA = 6/12 in BE. 10 x 12 mm localized tense cystic swelling in lateral 1/3rd of RLL,exendingupto lateral canthus Overlying skin shows few dilated vessels with yellowish deposits in mass.

13. Dermoid cysts Are choristomas,tissue anomalies c/d by types of cells not normally found at the involved site. Though,derived from all three germinal layers,ocular dermoids consists mainly ectoderm with mesodermal elements. Account for 3-9% of all orbital masses. About 50% of trs involving head are found in/adjascent to orbit.
14. Can be found in all age groups,but most commonly in adolescent age groups. Most frequent site - supero temporal quadrant of orbit [in relation to frontozygomatic suture]. In eye,other sites are limbus, eyebrows, conjunctiva and rarely eye lids.
