A partial or complete failure in the involu�tion of the primary optic vesicle resulting in the formation of a cyst according to Duke Elder[1] is a rare anomaly. Sometimes the cyst is small producing a picture of anophthalmos. On the contrary the cyst may be quite large, even larger than the normal eye. Such a cystic eye is thin-walled with a bluish tinge and occupies the centre of the orbit. It may pro�duce a bulging on the lid, particularly the upper. The lids and conjunctival sac are fully developed and the orbit, although sometimes normal, is usually reduced in size. We present here a case of unilateral congenital ectopic eyeball, encysted in the substance of the lower lid.


M.L., a 8 years old Hindu boy was brought to the eye department with the history of the absence of the left eye ball and a swelling around the left lower lid since birth; systemic examination revealed no abnormality. Visual acuity in the normal looking right eye was 6/6. Left eye was absent from the orbital socket. The orbital cavity was contracted and lined with normal looking conjunctiva. There was a round shaped bulge over the lower lid [Figure 1].

Surgery was undertaken under general anaesthesia. Through a linear skin incision, 2 cm below and parallel to the lower lid margin, the mass was exposed. It looked like an eye ball with bluish tinge of its walls and felt cystic to palpation. No extra ocular muscle could be made. out: A withish tract extended from its posterior pole towards the orbital floor. While handling this tract sudden bradycardia resulted, 0.6 nag of At ropi ne Sulph. was prom�ptly administered intravenously and the pulse rate quickly returned to normal. It was presumed that the occurence of bradycardia was via the oculocardiac reflex, produced by handling the ectopic eyeball and connected soft tissues. The cystic mass was freed from the surrounding tissue and removed in toto [Figure 2] Postoperative recovery was unevent�ful. Subsequently a prosthesis has been fitted to bring about a satisfactory cosmetic appearance [Figure 3].


In the rare incidence of the failure in involution of the primary optic vesicle. when the eyeball is replaced by a cyst, it usually occupies either the centre of the orbit or pro�duces it bulge on the upper lid.

The presentcase is unusual in the sense that the ectopic encysted eyeball was totally lodged in the lower eyelid and partially extended onto the malaf eminence. It is also considered necessary to remember the possibility of stimulating the oculocardiac reflex while handling ectopic eyeballs, as encountered by us in this case.


A rare case of congenital ectopic eyeball, encysted in the lower eyelid, has been reported.
