Effects of Fat Repositioning for Tear Trough Deformity on Eye Movement.

ABSTRACT: Fat repositioning is a common surgical technique for treating tear trough deformity. As this technique is mainly performed for cosmetic purposes, its functional outcomes have rarely been evaluated. The purpose of this study was to evaluate the changes in eye movements that occur after fat repositioning for tear trough deformity. The authors performed fat repositioning on 18 eyelids of 9 patients and evaluated their eye movements and binocular vision before surgery and at 1, 3, and 6 months after surgery. Hess screen and Binocular single vision tests were performed during each follow-up examination and the scores were recorded. The authors observed that fat repositioning did not affect binocular vision; however, vertical and horizontal eye movements worsened at 3 months after surgery. Nevertheless, there was no significant difference between the eye movements recorded before surgery and those recorded 6 months after surgery. Regardless of this finding, it should be noted that vertical or horizontal strabismus might occur after fat repositioning for tear trough deformity.

Combination of Dermal fat Grafting and Frontalis Suspension Using Polytetrafluoroethylene Sheet for Blepharoptosis With a Deep Sulcus.

ABSTRACT: The frontalis suspension procedure is a common surgical method for patients with severe blepharoptosis. While frontalis suspension is a very effective method, the transplant material may be visualized after surgery in patients with a deep sulcus and severe blepharoptosis. To prevent this complication, we performed a combination of dermal fat grafting and frontalis suspension using a polytetrafluoroethylene sheet in 5 patients (6 eyelids). We followed-up the patients for at least 6 months postoperatively (mean: 6.8 months) and observed no transplant material visualization or occurrence of infection. The mean pre- and postoperative margin reflex distance-1 was -3.75 (-5 to -2) and 2.10 (1-3), respectively. Bulky upper eyelids were observed 6 months postoperatively in 1 patient (2 eyelids). None of the patients underwent reoperation. In conclusion, the combination of frontalis suspension using a polytetrafluoroethylene sheet and dermal fat grafting for severe blepharoptosis and a deep upper eyelid sulcus was effective in preventing visualization of the transplant material.

A New Surgical Method for Medial Ectropion Repair: Fixing the Lower Eyelid Retractor to the Back of the Tarsal Plate.

ABSTRACT: Involutional ectropion is a disease in which the eyelids are everted outwards, and because the eyelids move away from the eyeballs, the ocular surface and conjunctiva are exposed causing inflammation, pain, photophobia, foreign body sensation, epiphora, and blurred vision. It is thought to be caused by horizontal and vertical laxity. Various surgical methods have reportedly been used to correct involutional ectropion. Shortening the lower eyelid retractor (LER) is an indispensable surgical operation for medial ectropion. When the LER is shortened, it is usually fixed to the lower edge of the tarsal plate. Herein we describe a new type of surgery that has now been performed on 6 eyes in 4 patients. The procedure involves separating the conjunctiva from the tarsal plate, inserting the LER between the conjunctiva and the tarsal plate, and then fixing it to the back of the tarsal plate. In all 6 eyes, the lower eyelid now contacts the eyeball, and morphological improvements were achieved. This new surgical method is a useful way to raise the tarsal plate.
