Purpose

To report a rare and late oculoplastic complication of retinal detachment surgery.

Methods

A 71-year-old man attended the oculoplastic clinic complaining of drooping eyelids. His past ophthalmic history included left retinal detachment repair 20 years previously. On examination, he had bilateral moderate dermatochalasis and left aponeurotic blepharoptosis. Lid crease height was 8mm on the right and 10mm on the left. Margin reflex distance (MRD) 1 was 5mm on the right and 1mm on the left, with MRD2 of 5mm on both sides. Levator function was 14mm on the right and 12mm on the left. Motility was otherwise normal. The left tarsal plate was notably thickened and yellow.

The patient underwent bilateral upper lid blepharoplasty and left ptosis repair. As the first skin incision was made on the left upper lid, a discharge of oily refractive particles was noted. Approximately 2ml of silicone oil was expressed from the lid and surgery continued without complication.

Results

At 2 weeks post-operatively, lid crease height was 8mm on both sides. MRD1 was 5mm on the right and 4mm on the left, with MRD2 of 5mm on both sides. Levator function was 14mm on the right and 13mm on the left. Wounds were healing well and the patient was very satisfied with the results. Visual acuity was 6/9 in both eyes with normal intraocular pressure and normal fundal examination.

Conclusion

Migration of silicone oil from the vitreous cavity causing mechanical ptosis is a rare and late complication of retinal detachment surgery. We identified 5 previous similar case reports with presentation between 2 months and 12 years after oil implantation. At 20 years, this case is the latest documented presentation of such a complaint.
