The current alternative for ocular surface and anophthalmic socket reconstruction, cryopreserved umbilical amniotic membrane (cUAM).

PURPOSE: This report presents the results of using cryopreserved umbilical amniotic membrane (cUAM) as an alternative mucosal graft for ocular surface reconstruction in cases of anophthalmic socket contracture (ASC), cicatricial entropion (CE), and conjunctival-scleral defects. METHODS: The study included patients who underwent non-commercial implantation of cUAM grafts (prepared by corneal banking methods) for ASC, CE, conjunctival defect, and scleral melting. The main success criteria for this study were the comfortable fitting of the ocular prosthesis in ASC patients, the natural eyelid position in CE patients, and the degree of conjunctivalisation in melting patients. RESULTS: cUAM transplantation was performed in 2 patients who could not use a prosthetic eye due to conjunctival contracture, 2 patients with CE, and 1 patient with conjunctival defect and 1 patient with conjunctival-scleral melting. The primary outcome was achieved in 83.3% (5/6) of patients. In one patient with CE, partial healing was achieved due to the persistence of CE in the medial upper eyelid. CONCLUSIONS: cUAM is a viable alternative to mucosal grafting for reconstructing the bulbar and palpebral conjunctival surface, fornix, and orbit, with reduced donor morbidity and shorter surgical time. Its regenerative ability allows for tissue defect healing and improves cosmetic appearance through epithelialization within weeks.

Reducing tension step by step in epicanthus and lower eyelid incision for treating cilial entropion in children: A case series analysis.

OBJECTIVE: To evaluate the surgical outcomes of a modified technique for treating congenital cilial entropion in children, which involves reducing tension step by step in the epicanthus and lower eyelid incision. METHODS: The observational group consisted of 153 pediatric patients (81 males and 72 females) who were treated using the modified technique, whereas the control group included 124 patients (68 males and 56 females) who were treated using the rotating suture surgery. All the participants were bilateral. Surgical outcomes were classified as good, fair, or poor, and the recurrence rate, scar condition, inferior eyelid position, and patient satisfaction were also assessed. RESULTS: The mean follow-up period was 9.13 ± 3.50 months (range: 3-14 months) for the observational group and 6.93 ± 4.51 months (range: 3-14 months) for the control group. In the observational group, surgical success with "good" outcomes was achieved in 300 eyes (98.04%), compared to 224 eyes (90.32%) in the control group. No recurrence occurred in the observational group, whereas the recurrence rate in the control group was 4.43%. Postoperative scar formation was mild in the observational group. The average scar score was 1.27 ± 0.96 in the observational group and 2.70 ± 0.99 in the control group, with a statistically significant difference (P < 0.001). Neither overcorrection nor postoperative ectropion was observed in both groups. CONCLUSION: The modified technique effectively corrected medial entropion and trichiasis in the lower eyelid, resulting in stable postoperative outcomes, mild scar formation, quick recovery, flexible eyelid motility, and stable ocular surface. Therefore, it can be widely applied to children with congenital entropion and trichiasis.

Trichiasis removal using dermatological punch: A case report.

Entropion, a common malposition of the eyelid, can lead to trichiasis and corneal damage. This article presents a clinical case in which, following initial surgery to correct entropion, the use of a dermatological punch was chosen to definitively eliminate persistent trichiasis. This relatively unknown yet effective approach proved to be a quick and straightforward alternative with positive outcomes, emphasizing the importance of considering innovative approaches to recurrent challenges in clinical practice.

Tarsal Buckling and Entropion after Levator Aponeurosis Advancement in Patients with Floppy Eyelid Syndrome.

Two patients with floppy eyelid syndrome presented with severe eye pain and foreign body sensation after recent levator aponeurosis advancement. The examination in both patients was notable for entropion of the upper eyelid, and upper lid eversion revealed deformity of the tarsus in both patients. Surgical revision with full-thickness horizontal tarsotomy and limited excision of the abnormal tarsus corrected the deformity. The authors propose a mechanism for this phenomenon and a modification of surgical technique that may prevent this complication.

Long-term success rate of entropion surgery is equivalent in juvenile and adult dogs.

OBJECTIVE: To compare long-term outcomes of lower lid entropion surgery performed in juvenile dogs versus adult dogs and evaluate the success rate of temporary tacking procedures in dogs < 1 year of age. ANIMALS: 116 client-owned dogs. METHODS: A retrospective study was performed evaluating dogs younger than 3 years old diagnosed with primary lower lid entropion between 2010 and 2020. Recurrence of entropion following temporary tacking sutures was evaluated. Surgical outcomes were evaluated of entropion surgery in dogs < and > 1 year of age. RESULTS: 44 dogs with entropion (71 eyes) had a temporary tacking procedure. The entropion resolved in 36.6% of eyes, requiring no further therapy. The median age of dogs successfully treated with a temporary tacking procedure was younger than those that failed. Forty-seven dogs (75 eyes) had entropion surgery at maturity, and 52 dogs (79 eyes) were juvenile. Twenty-seven dogs had temporary tacking procedure prior to surgery, accounting for the difference in number. There was no statistically significant difference in the recurrence rate of entropion between eyes of adult (6/75 [8%]) and juvenile dogs (10/79 [12.7%]) following surgery. CLINICAL RELEVANCE: Entropion surgery in juvenile dogs is not associated with a higher risk of recurrence and need not be delayed until dogs are older than 1 year of age.

Comparison of entropion outcome with and without intervention in Romane and Ile de France sheep breeds.

BACKGROUND: Congenital entropion is the most frequent ocular disorder in newborn lambs of certain sheep breeds, which, if not treated, can result in complete blindness and death due to starvation. OBJECTIVES: The aims of this study were to compare the spontaneous healing of entropion in two breeds and assess the outcome of cases with and without therapeutic intervention. METHODS: A total of 158 entropion cases (119 Ile de France and 39 Romane) were investigated, and swab samples were collected from the cornea and conjunctiva of 73 of the affected lambs for bacteriological investigation. In addition, an ocular intervention was carried out in 123 affected animals. RESULTS: The Romane breed developed entropion at an average age of 7 days compared to the Ile de France, which developed it at an average age of 1 day. Likewise, significant differences were found between bilateral and unilateral involvement in both breeds. Meanwhile, 22.1% of cases recovered spontaneously, and the highest rate of spontaneous recovery without intervention was observed in the Romane breed (66%). Bacteria isolated from ocular samples included Staphylococcus spp. (42.5%), Bacillus spp. (21.9%), Trueperella pyogenes (13.7%), Corynebacterium spp. (12.3%) and Escherichia coli (9.6%). CONCLUSIONS: The results of the study showed that the onset time of entropion, bilateral involvement, the severity of the process and the need for re-treatment were higher in the Ile de France breed than in the Romane breed. Likewise, the Romane breed showed a higher degree of spontaneous recovery of entropion.

Lateral tarsal strip procedure: comparison of absorbable sutures and non-absorbable polypropylene suture. Does the suture type matter?

BACKGROUND/OBJECTIVES: To determine whether the success and complication rates of the Lateral Tarsal Strip (LTS) Procedure, when treating involutional ectropion/entropion, is influenced by the use of suture when attaching the tarsal strip to the periosteum. SUBJECTS/METHODS: Multi-centre retrospective comparative study of re-operation and complication rates (Recurrence, Dehiscence, Suture Infection, Granuloma, Haemorrhage, Residual-Lid Laxity, Suture Extrusion and Repeat Procedure) in LTS, between 01/01/2017 and 01/01/2022 who met the inclusion/exclusion criteria, for involutional ectropion/entropion using an absorbable polyglactin (vicryl) and non-absorbable polypropylene suture (prolene). RESULTS: 1079 operations in 891 patients (36% female, average age 81.4 years) were performed with an average follow-up of 1.785 years. 588 operations in 475 patients were performed using prolene whilst 491 procedures in 416 patients were performed using vicryl sutures. Of these, 61% were performed by a consultant surgeon in the prolene group compared to 49.7% in the vicryl group. Overall complication rates between prolene and vicryl were 24.7% and 29.7% (p = 0.061) respectively. Higher complication rates for post-operative residual lid laxity, granuloma and suture infection were greater in the vicryl group versus prolene (2.65% and 0.51% p = 0.004, 2.24% and 0.68% p = 0.03, 1.83% and 0.17% p = 0.007 respectively). Non-significant results for dehiscence or repeat procedures (2.24% and 2.21% p = 0.974, 6.72% and 9.01% p = 0.166 respectively). CONCLUSIONS: Both sutures are effective for the correction of involutional ectropion/entropion with LTS. Dehiscence and redo rates were not statistically significant. Nevertheless, the use of vicryl suture was found to be associated with a higher complication rate for: post-operative residual lid laxity, granuloma and suture infection.

Comparison of Stab Incision and Eyelid Crease Incision Techniques in Children with Revision Frontalis Sling Surgeries Using Silicone Rods.

PURPOSE: To compare stab and eyelid crease incision techniques in revision frontalis sling surgeries using silicone rods. METHODS: This retrospective study involved 52 eyes in 48 consecutive pediatric patients who underwent revision frontalis sling surgery between 2008 and 2019. All primary surgeries were performed by making eyelid crease incisions and suturing of silicone rods onto the tarsal plates. The revision surgeries were performed by either making stab incisions over the eyelid through which to pass the silicone rods (group A), or by refixing the same or a new silicone rod to the tarsal plate (group B). The surgical results were compared. RESULTS: The mean follow-up period was 22.4 months (range, 6-62 months) and the mean age of the patients was 6.1 years (range, 1-16 years). There were 28 female and 20 male patients. Surgical success was achieved in 23 of 28 patients (82.1%) in group A, and 12 of 24 patients (50.0%) in group B. The difference between the groups was statistically significant (p = 0.012). Superficial punctate epithelial defects were detected in six group A patients (21.4%) and seven group B patients (29.1%). In group B, lid hematoma occurred in three patients (12.5%) and entropion occurred in three patients (12.5%). The silicone rods were removed from two eyes, and entropion spontaneously resolved in one eye with close follow-up. CONCLUSIONS: Using the stab incision technique increases revision frontalis sling surgery success rates when primary surgeries are performed using eyelid crease incisions and suturing silicone rods to the tarsal plates in children.

Preseptal transconjunctival approach in orbital floor fracture repairs to prevent postoperative lower eyelid malposition.

PURPOSE: Lower eyelid malposition can be a complication following orbital floor fracture surgeries. We present our incidence of lower eyelid malposition from a large case series of orbital floor fracture repairs using the 'swinging eyelid' approach and 'hang back' technique. METHODS: A retrospective review of all orbital fracture surgeries at our institution from November 2011 to March 2021 was performed. Primary outcomes included the incidence of lower eyelid malposition by category, the average time to presentation after primary surgery, and reoperation rates among cases with lower eyelid complications. RESULTS: A total of 438 cases that involved repair of the fractured orbital floor were identified. Six patients (1.37 %) developed lower eyelid malposition following primary orbital floor repair. Two patients (0.46 %) developed reverse ptosis of the lower eyelid. Two patients (0.46 %) returned with lower lid cicatricial ectropion. One patient (0.23 %) had postoperative lower eyelid retraction. One patient (0.23 %) had postoperative lower eyelid cicatricial entropion. No cases of lower lid flattening, lower eyelid fat flattening, or eyelid notch was noted. All patients with lower eyelid malposition underwent additional surgeries except one patient with reverse ptosis (83.3 %). The average time to the presentation of postoperative complications from the surgery date was 292.8 days (range = 49 days to 3.5 years). CONCLUSION: Lower eyelid malposition after orbital floor repair is a known complication that can be decreased by employing the 'swinging eyelid' with a preseptal approach and closure by the 'hang back' technique.

Eyelid Surgery in Thyroid Eye Disease.

PURPOSE: To review and summarize a comprehensive synopsis of surgery of the eyelid in thyroid eye disease (TED). METHODS: A PubMed search for specific eyelid manifestations of TED was performed. Studies reporting surgical management of these were reviewed, along with the author's own experience. RESULTS: The most common eyelid manifestations of TED include eyelid retraction, blepharoptosis, entropion, and epiblepharon, with most of them requiring surgical intervention. The correction of eyelid retraction has received maximum attention, with several surgical techniques that have stood the test of time. Blepharoptosis in TED that requires surgical intervention is usually aponeurotic. Entropion and Epiblepharon are rare in TED, and may resolve spontaneously, or following orbital decompression. CONCLUSIONS: Retraction is the commonest eyelid manifestation of TED, with multiple surgical options available for its correction. Blepharoptosis, entropion, and epiblepharon are rare eyelid findings in TED, that may occasionally require surgical correction.

[Subdermal hyaluronic acid injection treatment of an upper eyelid entropion in a rabbit]. / Subdermale Hyaluronsäureinjektion zur Behandlung eines Oberlidentropiums bei einem Kaninchen.

Surgical correction is the typical treatment for an entropion. However, considerable anesthetic risk exists for a subset of patients, particularly rabbits and guinea pigs. In a high number of these cases, this represents the main reason for reluctance to treat an entropion. The following report describes the case of a 9-year-old rabbit with a superficial cornea defect and a mild entropion of the upper eyelid. Eversion of the eyelid from a mild entropion to a normal position was attained by the subdermal injection of a hyaluronic acid filler (Alayna SG 24 Distinct®, BSC Medical Devices GmbH, Munich, Germany) without necessitating general anesthesia or sedation. Following a period of 273 days, a relapse occurred which was subsequently successfully treated with a repeat injection. An entropion of the contralateral eye became evident during the follow-up period and was also effectively managed by a single subdermal filler injection. In the reported case, treatment with subdermal hyaluronic acid injection proved to be well tolerated and efficacious.

Horizontal eyelid shortening alone versus combined procedures for the correction of involutional lower eyelid entropion.

BACKGROUND: Conventionally, management of involutional entropion involves correcting both vertical and horizontal laxity, however the optimal surgical approach is debated. OBJECTIVE: To compare the recurrence rate of horizontal lower eyelid shortening alone with combined surgical approaches for correction of involutional lower eyelid entropion. METHODS AND MATERIAL: A retrospective, comparative, consecutive case series of patients undergoing surgery for involutional lower eyelid entropion with both horizontal and vertical laxity. Patients were categorized based on the procedure as: Group 1, horizontal shortening alone, Group 2, horizontal shortening with everting sutures), and Group 3, horizontal shortening with retractor plication. RESULTS: Of the 249 procedures (31 bilateral) performed on 218 patients, 54 (22%) involved horizontal eyelid shortening alone (Group 1), while 80 (32%) had this combined with everting sutures (Group 2), and 115 (46%) with retractor plication (Group 3). The anatomical success rates for Groups 1, 2, and 3 were 93, 94, and 90% (P = 0.69), respectively. Similarly, reported symptom improvements were 94, 93, and 93% for these groups (P = 0.91). After an average follow-up of 15.7 months (median 10; range 6-81), Group 1 (eyelid shortening alone) had a 7% (4/54) recurrence, compared to 8% (16/195) in Groups 2 and 3 (combined procedures) (P = 1.0). Complications were minor, with no significant difference between groups. CONCLUSION: Eyelid shortening alone appears to be as effective as combined techniques for involutional entropion with both horizontal and vertical eyelid laxity. Nevertheless, procedure selection should consider primary pathogenic factors.

Everting Sutures for Involutional Entropion: A Non-incision, Simple and Cost-Effective Technique.

Entropion is one of the common eyelid marginal malposition and it causes irritation, and ulceration of the cornea that leads to visual loss of a patient. Patient may present with watering and foreign body sensation of the eye initially. Entropion may occur in the upper or lower eyelid. Involutional entropion is common and affected the lower eyelid. There are various non-surgical and surgical options to correct the entropion. Non-surgical procedures include taping the lower eyelid which relieves the entropion temporarily, botulinum toxin type-A injection into lower eyelid may temporarily relief the discomfort from entropion up to 6 months. This study was carried out to assess the outcome of the everting sutures for the correction of lower eyelid involutional entropion and to describe the cost effective of the procedure. A nonrandomized, non control group quasi experimental study was conducted in a Tertiary Eye Hospital, in Gopalganj, Bangladesh from January 2016 to December 2019. A less invasive everting sutures technique was applied for the correction of involutional entropion of eyelid. Follow up was maintained at regular intervals and we assess the outcome of the surgical techniques. We evaluated 33 eyes of 31 patients. The success rate was 87.88%. Recurrences were observed in 5(15.15%) eyelids in the 18 months follow up times. The time of the procedure was only 10 minutes, and the cost of the procedure was cheaper. Everting sutures was minimal invasive, non-incision, cost effective procedure for the correction of involutional entropion.
