Characteristics and perspectives of patients with postoperative trichiasis in Hadiya Zone, Ethiopia.

BackgroundPostoperative trachomatous trichiasis (PTT) is a challenge for trichiasis surgery programs. Little is known about PTT patients’ perceptions regarding outcomes and future disease management. This study aimed to understand the characteristics of PTT patients, how they managed trichiasis and their perceptions of prior surgeries and future surgery uptake.MethodsPatients with PTT were identified during an existing trichiasis screening program in Hadiya Zone, Ethiopia. A vision assessment and evaluation of the eyelids were conducted to determine distance vision, presence and severity of trichiasis and eyelid contour abnormalities. A questionnaire was administered to obtain information regarding patients’ perceptions of surgery and PTT management approaches. Descriptive statistics were used to characterize PTT and determine associations between PTT severity and patient perceptions.ResultsAmong 404 participants, most were female (79.7%) and aged 40–60 y (62.6%). In total, 514 eyelids had PTT, and nearly half had severe PTT (46.9%). Although >50% of participants were currently epilating to manage their PTT, the majority (82.8%) indicated that they wanted repeat surgery. Most participants indicated that pain persisted despite epilation. The majority (75.1%) indicated satisfaction with their prior surgery and 59.6% indicated that they would recommend surgery to others.ConclusionsThis study, which included a large proportion of severe PTT cases, indicated that individuals were generally satisfied with prior surgery and would prefer to have surgery again for PTT management.

Basal Cell Carcinoma Of Eyelid: A Surgical Challenge Solved

Basal cell carcinoma is the most common skin malignancy constituting 90% of eyelid tumors. Although it rarely metastasizes, it needs to be addressed with timely diagnosis and prompt treatment to avoid disfigurement of the tissues it invades. We report a case of 72 years old male with basal cell carcinoma of the lateral canthus. The patient was planned for an excision biopsy of the lesion. Despite the excision of a large tumor involving the lateral canthus of the left eye (3*3 cm) and a large portion adjoining the upper and lower eyelids (1.5 cm approximately), we were able to restore the eyelid contour at the lateral canthus. There have been many proposed treatment modalities for basal cell carcinoma however excision biopsy remains the gold standard. This article outlines the etio-pathogenesis, clinical features, and various treatment modalities in the management of basal cell carcinoma.

Surgical Approach to the Treatment of Upper Eyelid Retraction Caused by Prominent Filtration Bleb

Objective: To report on the technique of upper eyelid lengthening in patients with upper eyelid retraction not associated with Graves' disease but associated with bleb exposure and exposure keratitis. Case series: We present three patients (four eyes) with a history of glaucoma who underwent trabeculectomy with an active bleb with symptoms associated with bleb and corneal exposure due to retraction of the upper eyelid not associated with Graves' disease. All patients underwent surgical treatment to lengthen the upper eyelid by percutaneous complete blepharotomy with complete dissection of the orbicularis muscle, aponeurosis of levator palpebral muscle, Muller’s muscle and dissection of nasal and temporal conjunctiva reaching the superior border of the tarsus. In addition, the lateral horns of the levator muscle were resected, while preserving a strip of intact conjunctiva directly above the bulging bleb. Before and after surgery, the following measurements were made: including, visual acuity, retraction measurement, presence symptoms of dry cornea and bleb, MRD, and upper eyelid contour. Results: Preoperative upper lid marginal reflex distance (MRD) was measured. In addition, conjunctival staining of the bleb and cornea was recorded. Visual acuity ranged from 6/12 to 6/36. Upper eyelid retraction ranged from 3mm to 7.5mm, this was measured by calculating the marginal reflex distance (MRD) of the upper retracted eyelid minus 4.5 mm, representing the normal MRD. Amounts of lubricating drops used by patients per day was also recorded and quantified. The following postoperative measurements were recorded: MRD of upper eyelid; specifically including upper eyelid contour and position, present or absence of upper eyelid ptosis. Visual acuity improved by one line in the first postoperative week and maximum up to three lines after a month. A good cosmetic result was achieved. Conclusion: Blepharotomy is a surgical procedure suitable for the treatment of severe eyelid retraction. Preservation of the bridge of the intact conjunctiva over the bleb protects the bleb from traumatization in the postoperative period. This makes possible to use the blepharotomy in cases of eyelid retraction with exposure of the filtration bleb, and also maintain the correct contour of the upper eyelid.

Ophthalmic features and management of 86 patients with cryptophthalmos—A refined classification to assist in surgical planning

This study aimed to describe a cohort of patients with cryptophthalmos (CO), characterize associated oculofacial abnormalities, and expand the classification to summarize surgical strategies for managing CO. A retrospective, interventional case series was conducted on 86 patients (124 eyes) with CO. The study proposed further classifying complete and incomplete CO into cyst, microphthalmia, anophthalmia, and normal eyeball based on globe structures and then modifying surgery accordingly. The demography, ophthalmic features, systemic anomalies, operation methods, and treatment outcomes were reviewed. CO was complete in seven eyes (5.6%) and incomplete in eight eyes (6.5%). A total of 109 eyes (87.9%) of abortive CO were encountered. Among 15 eyes (13 patients) of complete and incomplete types, 9 (60.0%) eyeballs were identified as cysts, 3 (20.0%) as microphthalmia, 1 (6.7%) as anophthalmia, and 2 (13.3%) as normal eyeballs. Cyst reduction was performed in eight eyes and one patient underwent enucleation with hydroxyapatite implantation. The socket was fit with an ocular prosthesis or a conformer after fornix and eyelid reconstruction. Microphthalmia was enucleated, and hydroxyapatites were implanted; patients were fit with ocular prosthesis or conformer after fornix and eyelid reconstruction. A complete CO with normal eyeball was reported with the eyesight of hand movement after ocular surface reconstruction. The upper eyelid contour and adequate fornix were maintained after coloboma repair and fornix reconstruction in all patients with abortive CO. This study demonstrates the clinical manifestations of different types of CO and expands the manifestation spectrum, proposing a refined classification of CO and modifying surgical strategies accordingly.

Maximal Levator Resection Beyond Whitnall's Ligament in Severe Simple Congenital Ptosis with Poor Levator Function.

PurposeTo evaluate the functional and cosmetic outcomes, as well as factors that influence surgical success of maximal levator resection beyond Whitnall’s ligament in patients with poor levator function (LF) and severe simple congenital ptosis.MethodsThis retrospective interventional study included patients with severe simple congenital ptosis and LF of ≤4 mm who had undergone maximal levator resection beyond Whitnall’s ligament with a minimum of 12 months follow-up. Postoperative marginal reflex distance-1 (MRD1) was assessed for functional outcomes as excellent, good, fair and poor. Eyelid contour and the difference in MRD1 between eyes were assessed for symmetrical cosmetic outcomes as excellent, good and poor. Demographic data, factors influencing surgical success and postoperative complications were analyzed.ResultsA total of 38 ptotic eyelids in 31 patients were included. Successful surgical outcomes (at least good functional and cosmetic outcomes) were achieved in 26 patients (83.87%) with the mean MRD1 of +3.61 ± 0.27 mm and +3.51 ± 0.17 mm at 1 week and 12 months after surgery, respectively. There were no significant differences in demographic and preoperative data between the successful and unsuccessful surgical outcome groups, mean preoperative ptosis measurements were 4.19 ± 0.20 mm versus 4.72 ± 0.36 mm (p = 0.242) and mean pre-operative LF were 3.16 ± 0.15 mm versus 2.29 ± 0.61 mm (p = 0.561), respectively. The only factor that significantly influenced the surgical success rate was the length of the resected levator muscle. The mean lengths in successful and unsuccessful groups were 18.15 ± 0.44 mm and 14.29 ± 0.94 mm, respectively (p = 0.011).ConclusionMaximal levator resection beyond Whitnall’s ligament is an effective procedure for severe simple congenital ptosis with poor LF. Refinement of surgical techniques and careful assessment of the optimal resected length for the levator muscle grants successful surgical outcomes.

Frontalis Sling Using a Silicone Rod for Ptosis in Third Nerve Palsy: Cosmesis versus Safety.

PurposeTo evaluate the results of the frontalis sling operation using a silicone rod for the correction of ptosis in patients with third nerve palsy with a focus on corneal safety.MethodsPatients with third nerve palsy who underwent the frontalis sling operation using a silicone rod between 2008 and 2019 were included in this study. The medical records of all patients were reviewed, and their clinical characteristics and postoperative outcomes were analyzed. In this retrospective, interventional case series, the main outcome measures were eyelid contour, eyelid height by margin reflex distance, and corneal status.ResultsTwenty-four eyes of 18 patients (12 male and six female patients) were included. The mean age at the time of surgery was 35.1 years (range, 5–64 years). Twelve patients underwent a unilateral ptosis operation, and six patients received a bilateral ptosis operation. The mean follow-up period was 32.1 months (range, 2–87 months). Most patients (21 of 24 eyes, 88%) showed poor Bell’s phenomenon on preoperative examination. Satisfactory eyelid height and eyelid contour were achieved in almost all patients (mean postoperative margin reflex distance, +1.2 mm) postoperatively. Although corneal erosions were detected for several months in eight of 24 eyes after surgery, these findings were well controlled medically with artificial tear eye drops and ointments.ConclusionsFrontalis sling surgery using a silicone rod can safely and effectively correct ptosis without severe corneal complications in patients with third nerve palsy. Our study outlines a new method to define the postoperative safety outcome by specifically focusing on categorized corneal status.

Wide excision of eyelid tarsus with superficial lamellar lid margin tarsus excision for palpebral conjunctival melanoma

Conjunctival melanoma (CM) rarely occurs in the Chinese population. It is found more often in the non-bulbar area with worse prognosis compared with Caucasians. No consensus is reached regarding the standard surgical treatment of palpabral CM. We presented a 39-year-old Chinese female who developed CM at her right eye, involving superonasal palpebral conjunctiva, superonasal bulbar conjunctiva and medial caruncle. We excised the lesion including underlying Tenon capsule and the main part of underlying tarsus with a maximum clear margin of 4 mm, while sparing the tarsus of the eyelid margin. We applied a hemi-depth lamellar incision on the eyelid margin tarsus to preserve the contour of eyelid. Double freeze-thaw cryotherapy was applied to the excision margin, and the conjunctival deficit was closed by an amniotic membrane graft. We provided post-operation adjuvant chemotherapy with 0.02% mitomycin C three times daily for a schedule of three weeks on, one week off. Good cosmetic outcome was achieved with no recurrence in the following 36 months. Tarsus is important in lid function and for aesthetic appearance. To achieve wide-enough safety margin and intact eyelid contour, we presented a new simple approach with good cosmetic outcome and desirable disease control in palpebral CM surgery.

Comparing the symmetry of upper eyelid following unilateral ptosis correction

BackgroundMargin Reflex Distance 1(MRD 1) only describes the central height of upper eyelid and relies on the examiner’s experience and disregards eyelid contour abnormalities. Therefore MRD 1 may not be sufficient for an acceptable result to evaluate the outcomes of ptosis surgery. The primary purpose of this study was to assess outcomes of unilateral ptosis correction based on parameters including degree of symmetry, MRD 1, peak height of the upper lid, temporal and nasal ocular surface area, and temporal/nasal area ratio with an objective, quantitative, and repeatable method.MethodsThis study was designed as a retrospective non-randomized case-control study. Medical records of the patients with unilateral ptosis between October 2015 and December 2020 were reviewed. Patients with unilateral ptosis who underwent surgical correction and levator function of 5 mm or greater were included in the study. Two groups were defined; ptotic eye was case group and contralateral eye was control group. Data analysis was performed Image J and Matlab softwares.ResultsThirty-four patients were included in the study. Mean age of patients was 58.8 ± 12.7 years (range 15–75 years). Mean follow-up time was 19.5 ± 7.3 months (range 8–40 months). Four patients were diagnosed with congenital ptosis and 30 patients aponeurotic ptosis. Mean preoperative degree of symmetry for overall eyelid contour was 36.6 ± 27.5% (range 1–92%). Mean postoperative degree of symmetry for overall eyelid contour was 72.4 ± 16.5% (range 55–92%). Temporal/Nasal (T/N) area ratios for contralateral normal eye was 1.19 pre-postoperative, and it was 1.11 preoperatively, 1.15 postoperatively for operated ptotic eye.ConclusionsThis study primarily demonstrated a quantitative, objective, and repeatable method to investigate the degree of symmetry after eyelid surgeries. Secondly, this study suggested that T/N ratio may not be a reliable parameter to evaluate the eyelid symmetry.

Upper Eyelid Contour Changes After Orbital Decompression in Graves Orbitopathy.

To evaluate the effect of orbital decompression on the upper eyelid contour. A paired cross-sectional analysis of the upper eyelid contour was performed for 103 eyes of 66 patients who underwent orbital decompression. A control group of 26 normal subjects was also included. The eyelid contour of all participants were measured with Bézier lines adjusted to the eyelid contour and 9 midpupil eyelid margin (MPD) distances from a horizontal line bisecting the pupil. One central, corresponding to the margin reflex distance (MRD 1), and 8 equally distributed medially and laterally at 20% of the interval between the lines. Patients were classified as with flare if the height of the most lateral MPD relative to the MRD 1 was above the upper limit of the controls. Preoperatively 63 of the 103 contours were classified as flare + (F+). After decompression MRD1 showed a mean decrease of 0.4 mm and the location of the contour shifted 0.8 mm medially. These changes were not correlated with proptosis reduction. Orbital decompression decreased the lateral curvature of the contours especially for the F+ lids. In 40% of the F+ eyelids the flare sign disappeared after decompression. Orbital decompression affects the lateral eyelid contour and diminishes the amount of lateral eyelid retraction surgery necessary to correct the flare sign. In 40% of the patients, the eyelid contour is normalized with proptosis reduction only.

A New Surgical Technique for Postoperative Trachomatous Trichiasis.

The World Health Organization has identified management of postoperative trichiasis (PTT) as one of the key remaining areas of focus needed to eliminate blinding trachoma as a public health problem. We developed the Bevel-Rotation Advancement Procedure (B-RAP) to treat individuals who need repeat trichiasis surgery. Scarring caused by trichiasis surgery can cause the eyelid to become thick and distorted, making repeat surgery more difficult. To minimize eyelid thickness following B-RAP, a beveled incision of the tarsus is made allowing a marginal rotation of the eyelash fragment. Dissection between the anterior and posterior lamellae above the beveled incision and removal of scar tissue allows the marginal rotation to be combined with a posterior lamellar advancement to treat severely scarred eyelids with PTT and eyelid contour abnormalities (ECAs). Two surgeons performed B-RAP on 44 eyelids of 30 patients with PTT. The number of prior trachomatous trichiasis (TT) surgeries ranged from 2 to more than 4. At the 3-6 months postoperative visit, 37 eyelids (84%) had no recurrence of PTT. Three eyelids had central lashes touching; the remaining eyelids with recurrent PTT had nasal and temporal lashes touching. Fifteen eyelids (34%) had ECAs, but only 1 was severe. B-RAP was developed considering the altered eyelid anatomy found in the postsurgical eyelid with TT. Thinning of the eyelash fragment and removal of postoperative scar tissue improves the ability to advance and stabilize the eyelash fragment after external rotation. B-RAP shows promise as a procedure for improving outcomes of repeat trichiasis surgery.

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

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. 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). 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). Predictable, targeted, and symmetrical lid crease can be obtained using the modified open method of tarso-frontalis suspension surgery.

How to determine the amount of levator resection in congenital ptosis repair

Background and objective: Levator aponeurosis resection is an effective technique to correct blepharoptosis when the levator function is fair to good. This study aimed to determine the amount of levator resection in congenital blepharoptosis repair. Methods: This is a prospective case series study conducted in Rizgary teaching hospital and private hospitals in Erbil city, Kurdistan Region, Iraq, from June 2011 to August 2019. The data of 53 patients (64 eyelids) affected by congenital blepharoptosis with poor to good levator function that underwent unilateral orbilateral levator resection blepharoptosis repair through the standard approach were included. The final outcome measures included postoperative eyelid height, contour, and symmetry. Results: This study includes a total of 53 patients with congenital blepharoptosis (64 eyelids); 20 males and 33 females. The age of the patients ranged from 3 years to 54 years, with a mean age ± SD of 14.11 ± 10.66 years. The ptosis was right sided in 22 patients (41.5%), left sided in 20 patients (37.7%), and bilateral in 11 patients (20.8%). The study showed good patient satisfaction in 66.03% of the cases, suboptimal satisfaction in 22.64% of the cases, and poor satisfaction in 11.32% of the cases. Conclusion: The levator resection for congenital ptosis is effective even with poor levator function and replaced in our practice the traditional fascial sling. We recommend that further studies be done on a larger number of patients to investigate the effectiveness of levator resection in patients with severe ptosis and very poor levator function.

Lateral sliding flap for one-step reconstruction of medium-sized eyelid defects

Background/purpose: To report the results of our clinical study on the efficacy of a ‘Lateral Sliding Flap’: A one-step technique for lower or upper eyelid reconstruction. Methods: Retrospective analysis of a consecutive case series of patients treated with a ‘Lateral Sliding Flap’ following tumour removal by horizontal block excision. In this technique a (medium-sized) defect of up to 50% of the eyelid was reconstructed by disinsertion of the lateral canthus, medial advancement of the lateral (remaining) (full-thickness) eyelid and a laterally-based horizontal skin-muscle advancement flap, followed by canthal fixation. We recorded the operating time and evaluated the postoperative eyelid apposition, lid contour, complications and frequency and type of re-operation. The outcome was scored (according to four grades (excellent/good/fair/ poor) of lid apposition and contour. Results: Seven consecutive patients, all treated by one oculoplastic surgeon in one year, were included. Six were female, one was male. Five had lower eyelid defects, two had upper eyelid defects of 40-50% of the horizontal width. The average age was 67,9 years, ranging from 52 to 85 years. The mean postoperative follow-up time was 31 months, ranging from 21-43 months. The average duration of the reconstruction was 31 minutes (ranging from 25 to 38 minutes). The outcome was excellent in 3 patients, good in 3 patients and fair in one patient. (Some) lash loss may be encountered. No complications such as flap ischemia of necrosis were noted. No re-operation was required. Conclusion: The ‘Lateral Sliding Flap’ is an efficaceous, one-step technique for reconstruction of defects of up to 50% of the lower or upper eyelid. With the technique a normal eyelid margin is created at the level of the cornea for optimal visual function and comfort. Compared to Tenzel’s semicircular rotation flap, the ‘lateral sliding flap’ results in a shorter vertical scar and “Hidden” horizontal scars in the relaxed skin tension lines.

Improved Eyelid Muscle Tension Balance With Refined Frontalis Muscle Flap Suspension in the Treatment of Severe Ptosis.

The tension balance of the upper eyelid following ptosis repair is crucial to a successful postoperative outcome. To improve on existing surgical techniques, the authors developed a new refined frontalis muscle flap suspension (FMFS) for severe ptosis repair and explored the balancing effect between the orbicularis muscle and frontalis muscle following surgery. Forty-three patients (47 eyes) with a mean age of 6.07 ± 2.55 years old were diagnosed with severe congenital ptosis and underwent refined FMFS with complete orbicularis preservation between January 1, 2010 and December 31, 2017 in the Wenzhou Eye Hospital, Wenzhou, China. The outcomes measured include upper eyelid margin reflex distance (MRD1), degree of lagophthalmos, and cosmetic outcome (lash angle, eyelid contour, and crease). Surgical complications were also recorded. The preoperative mean MRD1 was -1.29 ± 0.88 mm and preoperative levator function was 1.87 ± 0.82 mm (ranged from 0 to 3.0 mm). Following surgery, lagophthalmos was observed in all cases in the first week with a mean palpebral fissure height of 1.68 ± 0.40 mm and diminished over 3 months. The MRD1 improved to +3.04 ± 0.68 mm at 6 months following surgery. All cases showed excellent cosmetic outcomes. There were no significant complications. The refined FMFS is a safe and reliable surgery in treating severe ptosis. The eye-closing power of the intact orbicularis muscle is sufficient at countering the lifting power of the frontalis muscle suspension, achieving a balanced blink mechanism and eyelid closure.

Fan-Shaped Thin Fat Pedicles for Tear Trough Correction Through a Layer-Level Fixation: A Modified Transconjunctival Blepharoplasty.

Fat repositioning is an effective way to treat tear trough deformity (TTD) in Asians. Recent techniques mainly focused on the fixation technique, whereas how to precisely shape and individually quantify the fat pedicle has been ignored. This article introduced an individualized, targeted, and tension-free technique to fabricate a fan-shaped thin septum fat pedicle for repositioning. Furthermore, a layer-level fixation method was advocated to provide sufficient, continuous, uninterrupted filling of the TTD. From January 1, 2009, to December 31, 2018, 492 patients underwent this procedure. Through a transconjunctival incision, a continuous fan-shaped, tension-free, customized septum fat pedicle was precisely designed to match the TTD anatomy. The pedicle could either be elongated, or thickened, or debulked, or translocated, to meet the patients' individual needs. At the same time, a layer-level fat pedicle fixation technique was applied to fully interrupt the TTD. The mean operation time was 60 ± 9.3 minutes. All patients demonstrated a significant improvement with elimination of both eye bags and TTD. High satisfaction was noted among the patients. No obvious resorption of the fat pedicles was observed, and the lower lid contour improvements were durable. One infection occurred after 3 days of surgery, and was resolved by removal of the suture followed by topical application of iodine and oral antibiotics for 3 to 5 days. No other complications were observed. Precisely repositioning transconjunctival fat using a layer-level fixation technique with a fan-shaped thin fat pedicle under a subperiosteal plane is an effective, lasting, and safe approach for individually treating TTD.

Outcomes of optic nerve sheath fenestration from superomedial eyelid crease approach

ABSTRACT Purpose The purpose of this study is to report the safety and outcomes of optic nerve sheath fenestration (ONSF) performed via superomedial eyelid crease approach. Methods A retrospective chart review was performed on patients undergoing superomedial eyelid crease ONSF at a single institution between 2014-2019. Data obtained included preoperative visual acuity (VA), mean deviation (MD) on visual field (VF), papilledema grade, intraoperative time, estimated blood loss, intraoperative complications and optic nerve sheath biopsy results. Postoperative month 6 (POM6) data collected included VA, MD, papilledema grade, and lid contour. Outcome measures included overall change in VA, MD, and papilledema grade at POM6. Statistical analysis was performed using STATA version 16 statistical software. Data analysis was done comparing all patients pre- and postoperatively. Additional subgroup analysis was performed on patients undergoing ONSF for IIH vs other indications, and on the contralateral unoperated eye. Results A total of 31 eyes of 24 patients were identified, four of whom were excluded due to being lost to follow-up. At POM6, improvement was seen in VA (p<0.001) across all groups. There was improvement in POM6 median papilledema grade and MD, but these did not reach statistical significance. Additional subgroup analysis on patients with IIH showed statistically significant improvement in POM 6 VA (p=0.009), papilledema (p=0.009) and MD (p<0.001), as well as VA improvement in the contralateral unoperated eye (p<0.001). Conclusions Superomedial eyelid crease approach for ONSF is a safe and effective surgery in IIH and other conditions of excess pressure within the optic nerve sheath.
