Astigmatism Characteristics and Surgical Outcomes in Younger Children With Severe Congenital Ptosis After Frontalis Suspension Surgery

Background: To examine the astigmatism characteristics and surgical outcomes in patients with unilateral severe congenital ptosis following frontalis suspension surgery.Methods: We included 53 congenital ptosis patients who underwent frontalis suspension surgery in Hunan Children‘s Hospital. Each patient underwent a refractive examination before and after surgery to assess astigmatism. We also evaluated the effects and complications associated with the procedure.Results: Degree of astigmatism in ptotic and fellow eyes was -1.45±0.59 D and -0.66±0.51 D before surgery. Ratio of severe astigmatism in ptotic and fellow eyes was 51.3% and 12.8%. The fellow eyes presented with with-the-rule astigmatism (WR; 71.8%) and against-the-rule astigmatism (AR; 20.5%) types, with no cases of oblique astigmatism (OA). Ptotic eyes demonstrated higher frequencies of AR (59.0%) and OA (10.2%) than did fellow eyes. Furthermore, the former showed increased astigmatism, followed by a gradual decrease at the 6-month, before significantly decreasing at the 1-year postoperatively. The ratio of postoperative AR and OA astigmatism cases in ptotic eyes decreased to 35.9% and 7.7% 1 month postoperatively. However, there was a postoperative increase in the WR ratio from 30.8% to 56.4% after 1 month. Kaplan-Meier survival analysis showed a success rate of 81.4% at 6 months and 62.9% at 12 months which was influenced by the following complications: suture reaction, epithelial keratopathy, infection and granuloma, lid lag, and recurrence. Conclusion: Frontalis suspension surgery can effectively and safely correct congenital ptosis in younger patients, which may ameliorate the development of amblyopic astigmatism.

Treatment of Severe Ptosis by Conjoint Fascial Sheath Suspension

Objective. To explore the role of conjoint fascial sheath (CFS) suspension in the treatment of severe ptosis. Methods. A total of 110 patients with severe ptosis who were admitted to our hospital from May 2018 to December 2020 were included. Fifty-seven patients treated with frontalis suspension were assigned into group A, and the remaining 53 patients treated with CFS suspension were assigned into group B. The curative effect, ocular surface alterations, complications, and satisfaction in the two groups were compared. Results. Patients in group B suffered from severe upper eyelid retraction and lid lag than those in group A, as well as more limited range of motion (ROM) ( P < 0.05 ). The curative effect and patient satisfaction in group B were higher than those in group A ( P < 0.05 ). Postsurgical complications in group B were fewer than those in group A ( P < 0.05 ). Conclusion. CFS suspension is effective in the treatment of severe ptosis.

Conventional versus Modified Tarso-frontalis Suspension Surgery using Targeted Lid Crease for Simple Congenital Blepharoptosis with Poor Levator Action

Introduction: The routine technique of tarso-frontalis suspension surgery for simple congenital blepharoptosis with poor levator action is cosmetically less rewarding due to either an absence or asymmetry of the postoperative eyelid crease. The objective of this study was to assess the eyelid crease quality after a modified open method of tarso-frontalis suspension surgery compared to the closed method. Materials and methods: This was a retrospective comparative study reviewing the case sheets of all the patients undergoing unilateral tarso-frontalis suspension surgery with silicon rod employing Fox pentagon design from September 2017 to February 2019 at Mechi Eye Hospital, Jhapa, Nepal. A review of 40 case sheets of congenital lid ptosis with poor levator function(<4mm) aged 9 years or more was done. Tarso-frontalis suspension surgery, modified with a mini blepharoplasty incision, direct attachment of silicon rod to tarsus, completion of pentagon design with supra-brow incisions, and skin-orbicularis-tarsus-orbicularis-skin suture (open method) was done in 20 cases whereas other 20 cases underwent surgery with supraciliary stab incisions (closed method). Results: The mean age of the patients was 21.1+5.9 years (range 9-30 years). The ptosis amount ranged from 3–10mm. At the 6th postoperative month, most of the cases had good ptosis correction (90% open group, 85% closed group, p=0.74). However, cosmetic outcomes were better in the open group compared to the closed group: 100% symmetrical eyelid crease compared to 40% (p<0.001) and 90% acceptance rate for eyelid contour compared to 70% (p=0.23). Conclusion: Predictable, targeted, and symmetrical lid crease can be obtained using the modified open method of tarso-frontalis suspension surgery.

Predicting the Success Rate of Levator Resection Surgery Using Whitnall Ligament Position

Ptosis is defined as lower positioning of the upper eyelid margin which normally is placed 1.5 mm below the superior corneal limbus [1]. Ptosis can be accounted as the 3rd most common eyelid disorders following chalazion and entropion [2]. It may result in amblyopia, visual field defect, cosmetic and psychological problems. Generally, ptosis is subdivided to congenital and acquired cases [3]. Abnormal development of levator muscle or innervation abnormalities is responsible for congenital cases of ptosis. On the other side, trauma, several neurologic disease, and defective levator aponeurosis can lead to acquired ptosis [4]. Levator function, clinical feature, and concomitant eyelid or face abnormalities are the determining factors for choosing appropriate surgical plan [5]. Common surgical approaches include frontalis suspension technique and levator muscle procedures (levator advancement and levator resection) in which frontalis suspension is performed in cases with poor levator function and the latter one is suitable for patients with preserved levator function [4]. Levator resection outcomes are not absolutely predictable. Multiple factors such as ptosis severity, levator function, and age of patient have been discussed as predictive factors for surgical success rate.

An Inflammatory Reaction to Stored Fascia Lata 37 Years Postimplantation

We report a rare case of a suspected inflammatory reaction to stored fascia lata 37 years post-placement. Clinical, imaging, histopathological, and immunohistochemical findings are presented, with a literature review on reactions to stored fascia lata. A 39-year-old woman had upper eyelid congenital ptosis repaired successfully at 2 years with bilateral frontalis suspension procedures using stored fascia lata. Thirty-seven years later, the patient presented with swelling of her eyelids and forehead, which was tender to the touch, in the same pattern as the fascia lata slings placed earlier. Histopathological examination disclosed a non-necrotizing granulomatous inflammatory infiltrate with numerous asteroid bodies. Initially, it was responsive to oral prednisone, but with recurrent inflammation, long-term methotrexate was required to control the inflammation. To our knowledge, this type of delayed inflammatory reaction has not been previously reported. It raises a concern about the use of allogeneic donor tissue and accepted sterilization techniques that may not be 100% effective in deactivating all components of the donor graft, including potential infectious pathogens, leading to a subsequent latent reaction.

The Function-Preserving Frontalis Orbicularis Oculi Muscle Flap for the Correction of Severe Blepharoptosis With Poor Levator Function

Background Severe blepharoptosis with poor LF has traditionally been managed with exogenous frontalis suspension but complications such as lagophthalmos, infection, rejection were often reported. Objectives The function-preserving frontalis orbicularis oculi muscle (FOOM) flap was designed to correct severe blepharoptosis with poor levator function (LF). With preservation of the OOM function, the long-term surgical outcome of the technique was assessed. Methods This retrospective study included only adult patients with severe blepharoptosis and poor LF, all of whom had their surgery performed by the senior surgeon, Lai CS, over a 6-year period. Clinical assessment of LF, palpebral fissure height (PFH), marginal reflex distance 1 (MRD1), duration of follow up, and postoperative complications were recorded. Results 34 patients and 59 eyelids were recorded during a mean follow-up period of 17.7 months. Postoperative evaluation yielded improvements of an average PFH gain of 5.62 ± 1.61 mm (p &lt; 0.001) as well as MRD1 and PFH increase by an average of 4.03 ± 0.82 mm (p &lt; 0.001) and 8.94 ± 0.81 mm (p &lt; 0.001), respectively. All patients demonstrated normalization of orbicularis function as no lagophthalmos was observed at the 8-month postoperative follow up. Recurrence of ptosis were recorded in four eyelids (6.78%). Revisions were performed in two eyelids (3.39%). No infection or granuloma was noted. Conclusions The function-preserving FOOM flap is a useful vector for frontalis suspension. Not only does it effectively address lagophthalmos as well as other complications, but it provides aesthetically pleasing outcomes in patients with severe blepharoptosis and poor LF.
