Congenital eyelid imbrication syndrome: A rare occurrence in Pakistan.

Congenital eyelid imbrication syndrome (CEIS) is a rare condition presenting at birth and is characterised by overriding of the upper lid on the lower lid. It is due to longer upper lid, than the lower lid. Overriding leads to spontaneous eversion of the upper lids. In our patient, examination revealed canthal tendon laxity and hyperaemia of the tarsal conjunctiva. All the rest of the structures in the eyeball and adnexa were normal. Spontaneous eversion occurred in two weeks as the upper lid grew with time. No treatment was required.

[A case of eyelid fistula after cosmetic lateral canthoplasty].

A 35-year-old female presented with a chief complaint of exudates from the outer corner of the left eye for more than half a year after cosmetic lateral canthoplasty. A fistula was seen in the skin of the left eye 5 mm from the lateral canthus, with clear fluid inside it. Left eyelid fistula was diagnosed and surgically removed. The histopathological examination confirmed that the tissue connected with the fistula was lacrimal gland tissue. No recurrence was found during the 2-month follow-up.

Relationship between histopathological findings of patients with dermatochalasis and vitamin D deficiency.

PURPOSE: To compare the histopathological findings of patients who had been diagnosed with dermatochalasis (DC) and had undergone upper eyelid blepharoplasty (ULB) as well as those of controls (C-Group) according to their serum vitamin D (SVD) levels. METHODS: The prospective study included 136 upper eyelid skin from 68 patients who underwent surgery for DC and 53 upper eyelid skin from 53 patients who underwent levator surgery with ULB. The DC Group was then divided into 3 subgroups according to the marginal reflex distance (MRD4). The lymphatic vessel (LV) count and diameter of the largest LV (DLLV) were recorded, the stromal collagen bed (SCB) was observed, and its depth was measured, the interfibrillar edema was examined, and the elastic fiber and macrophage counts and recorded, respectively, and then all of these were evaluated. The SVD levels were compared between the DC patients and the C-Group. RESULTS: In comparison to the C-Group, significant changes were seen in the dilated LV, DLLV, SCB depth, interfibrillar edema, elastic fiber density, and macrophage count in the DC sub-Groups (P < 0.001 for all). While no difference was found between DC sub-Group 1 (MRD4 > 4 mm) and the C-Group (P > 0.05), a significant difference was found between DC sub-Group 2 (MRD4 2-4 mm) and DC sub-Group 3 (MRD4 < 2 mm) for all of the parameters (P < 0.05). A statistically significant difference was also found in the SVD levels between the DC sub-Group 1 and DC sub-Groups 2-3 (P < 0.017, P < 0.001 respectively). CONCLUSION: According to the results of this study, SVD level was significantly lower in DC group. Moreover, an increased LV count and diameter, decreased elastic fiber count, collagen fiber and stromal edema irregularity, and increased macrophage count were found to be associated with the SVD level.

Lower eyelid retraction repair using autologous auricular scapha cartilage.

PURPOSE: To assess the efficacy of lower eyelid retraction surgery utilizing autologous auricular scapha cartilage (located within the anterior surface groove between the helix and anti-helix) and to present the surgical outcomes in a patient cohort. METHODS: Medical records of 21 patients who underwent lower eyelid retraction surgery with scapha cartilage were retrospectively reviewed. Retractions, present for an extended duration (6 months to 20 years), exhibited 1 mm or more inferior scleral show, attributed to prior lower eyelid blepharoplasty, facial palsy, or as a normal anatomical variation. Surgical interventions included lateral canthotomy, cantholysis, incision of the subtarsal conjunctiva-lower eyelid retractors, lower eyelid retractor lysis, cartilage graft suturing to the defect area without conjunctival cover, and tightening of the lateral canthal corner in all patients. RESULTS: A total of 29 eyelids in 21 patients underwent surgery without intraoperative complications. Over a mean follow-up period of 11 months (range: 6-30 months), lower lid retraction improved in 96.5% of eyelids. Postoperative margin-to-reflex distance measurements (MRD2) significantly decreased compared to preoperative values (p = 0.001; p < 0.01). Average improvements in MRD2-a (midpupil to lower lid) and MRD2-b (lateral limbus to lower lid) were 1.77 ± 0.80 and 2.04 ± 0.81, respectively (p = 0.001; p < 0.01). Four eyelids (4/29) required revision due to canthal corner loosening, with correction necessitating periosteal flaps. All four patients had previously undergone two or more repairs elsewhere. The graft was visible in two lids but did not require further revision. One patient experienced mild helix deformity at the donor site, which did not warrant additional intervention. CONCLUSION: In cases of lower lid retraction associated with middle/posterior lamellar shortening, utilizing an autologous auricular scapha cartilage spacer graft offers notable benefits. These advantages comprise straightforward harvesting with minimal donor site complications, stability without experiencing shrinkage, a softer texture in comparison to posterior cartilage, a concave shape that facilitates proper fitting on the globe, and its autologous nature.

Morbihan Disease: A Rare Case of Periorbital Bilateral Edema with Histopathological Findings of Chronic Inflammation and Demodex Localization.

BACKGROUND Morbihan disease, also known as Morbihan syndrome, is a rare medical condition characterized by chronic facial edema predominantly affecting the upper two-thirds of the face. Despite being recognized in medical literature for decades, its true prevalence and underlying pathophysiology remain poorly understood. Various hypotheses, including impaired lymphatic drainage, abnormal vascular permeability, immune dysregulation, and inflammatory reactions to demodex infestation, have been proposed to explain the etiology. CASE REPORT We present a case of a 61-year-old man with organized periocular edema of the upper third of the face, ultimately leading to Morbihan disease diagnosis. The patient underwent a midface lift, allowing for tissue retrieval for histopathological examination of the eyelid edematous skin, which revealed chronic inflammation, ectasia of small lymphatic vessels, and features of demodex intrafollicular localization. These findings were not specific, but consistent with the diagnostic hypothesis. The patient was referred to a rheumatologist for further evaluation and treatment. He did not respond well to systemic corticosteroids and immunosuppressive therapy. Rather, this resulted in extension of the edema to the upper eyelid. The patient opted not to undergo further treatment. CONCLUSIONS Morbihan disease is often misdiagnosed due to its rarity and overlapping clinical features with other facial conditions. Its management is challenging and can require a combination of medical and surgical interventions. Systemic corticosteroids, immunosuppressive agents, and topical treatments have had varying success. Surgical procedures, such as blepharoplasty or laser therapy, can be considered in severe cases. Early recognition and appropriate management are crucial to improving patient outcomes and quality of life.

Case Report: Ophthalmomyiasis Externa Caused by Cordylobia anthropophaga Masquerading as a Lid Abscess.

Myiasis is a neglected tropical disease caused by the larvae of dipterous flies. Cutaneous infestation is the predominant type documented in sub-Saharan Africa, and ocular involvement is uncommon. We report the rare occurrence of a case of eyelid ophthalmomyiasis caused by Cordylobia anthropophaga in a Nigerian female to raise awareness among practitioners in both tropical and nonendemic areas.

Assessing neophyte response to daily disposable silicone hydrogel contact lenses: A randomised clinical trial investigation over one month.

OBJECTIVE: This randomised clinical trial assessed the impact on symptoms, tear film dynamics and ocular surface integrity of daily disposable silicone-hydrogel contact lenses (CLs) over a month, paying special attention to lid wiper epitheliopathy (LWE) and its implications for CL discomfort. METHODS: Neophyte CL wearers (n = 44, 21.09 ± 5.00 years old) were randomly assigned to either the experimental (n = 24) or control group (n = 20). Participants assigned to the experimental group were required to wear daily disposable CLs for 1 month for at least 8 h/day and 6 days/week. All participants were healthy subjects (no history of ocular surgery or active ocular disease) with spherical refractive errors between -8.00 and +5.00 D and cylindrical power <0.75 D. At the baseline and 1-month sessions, the Dry Eye Questionnaire 5 (DEQ-5) was completed, together with the measurement of tear film osmolarity with the TearLab osmometer, tear meniscus height (TMH) and lipid layer pattern (LLP) using a slit-lamp with Tearscope Plus attached, fluorescein break-up time (FBUT), maximum blink interval (MBI), corneal staining with fluorescein under cobalt blue light and LWE with lissamine green under slit lamp and halogen white light. RESULTS: At the baseline session, LWE showed a negative correlation with DEQ-5 (r = -0.37, p = 0.02). Significant differences in FBUT and LWE (p = 0.04) and a positive correlation between LWE and DEQ-5 (r = 0.49, p = 0.007) were observed at 1 month. Intrasession analysis at 1 month showed significant differences between the experimental and control groups in DEQ-5, FBUT and LWE (all p ≤ 0.02). Intersession analysis in the experimental group showed variations in DEQ-5, FBUT and LWE (all p ≤ 0.02) but no significant variation in the control group (all p ≥ 0.11). CONCLUSION: The presence of LWE was significantly correlated with higher symptom values in the DEQ-5. Also, participants in the experimental group presented higher values of LWE after 1 month of CL wear, in comparison with the control group.

Examining treatment strategies for xanthelasma palpebrarum: a comprehensive literature review of contemporary modalities.

Xanthelasma palpebrarum (XP) is the predominant form of cutaneous xanthoma, as it accounts for greater than 95% of cases. It is characterized by the presence of foam cell clusters containing a large amount of low-density lipoprotein (LDL), which are located in the connective tissue of skin, tendons, and fascia. XP lesions commonly present as distinctive yellow-orange macules, papules, or nodules, and are primarily on the upper eyelids as well as the inner canthus. Women are affected twice as often as men, with lesions typically emerging between the ages of 35 and 55. The pathophysiology of XP involves abnormal lipid metabolism and is often associated with hyperlipidemic states like Type II and IV hyperlipidemia, hypothyroidism, weight gain, and fatty diet. Despite the availability of various treatment methods, current XP management lacks standardization, particularly due to limited comparative research. To address this gap, we conducted an extensive literature review of 45 studies published between 2012 to 2023, which provides an updated overview of current XP treatment modalities. This comprehensive analysis will inform researchers and clinicians on the evolving landscape of XP management.

A Magnetic Actuator Device for Fully Automated Blinking in Total Bidirectional Eyelid Paralysis: First Proof of Concept in a Human Participant.

Purpose: Currently, no solution exists to restore natural eyelid kinematics for patients with complete eyelid paralysis due to loss of function of both the levator palpebrae superioris and orbicularis oculi. These rare cases are prone to complications of chronic exposure keratopathy which may lead to corneal blindness. We hypothesized that magnetic force could be used to fully automate eyelid movement in these cases through the use of eyelid-attached magnets and a spectacle-mounted magnet driven by a programmable motor (motorized magnetic levator prosthesis [MMLP]). Methods: To test this hypothesis and establish proof of concept, we performed a finite element analysis (FEA) for a prototype MMLP to check the eyelid-opening force generated by the device and verified the results with experimental measurements in a volunteer with total bidirectional eyelid paralysis. The subject was then fitted with a prototype to check the performance of the device and its success. Results: With MMLP, eye opening was restored to near normal, and blinking was fully automated in close synchrony with the motor-driven polarity reversal, with full closure on the blink. The device was well tolerated, and the participant was pleased with the comfort and performance. Conclusions: FEA simulation results conformed to the experimentally observed trend, further supporting the proof of concept and design parameters. This is the first viable approach in human patients with proof of concept for complete reanimation of a bidirectionally paretic eyelid. Further study is warranted to refine the prototype and determine the feasibility and safety of prolonged use. Translational Relevance: This is first proof of concept for our device for total bidirectional eyelid paralysis.

Blink Lagophthalmos in Graves Orbitopathy.

PURPOSE: To investigate the relationship between the kinematics of spontaneous blinks and the anterior area of the levator palpebrae superioris muscle in patients with Graves orbitopathy (GO). METHODS: This is a case-control study. The authors measured the margin reflex distance of the upper eyelid (margin reflex distance 1), the kinematics of spontaneous blinks, and the anterior area of levator palpebrae superioris muscle in CT coronal scans of patients with Graves upper eyelid retraction (GO) and a control group. The eye with the greatest margin reflex distance 1 was selected for analysis in each group. RESULTS: A total of 68 participants were included, with 36 in the GO group and 32 in the control group. In the GO group, the mean margin reflex distance 1 measured 6.5 mm, while in the control group, it was 3.9 mm. Almost all parameters related to the closing phase of spontaneous blinking activity, including amplitude, velocity, blinking rate, and interblink time, did not differ between the two groups. However, the effectiveness of the blink's amplitude (ratio of blink amplitude to margin reflex distance 1) and the main sequence (relationship between amplitude and velocity) were significantly reduced in the GO group compared with the control group. The area of the levator palpebrae superioris muscle was significantly larger in GO than in controls, with 71.4% of patients' muscles outside of the maximum range of the controls. CONCLUSIONS: In patients with GO, there is a reduction in blinking effectiveness, also known as blink lagophthalmos, which is a factor in the common occurrence of ocular surface symptoms. The increase in velocity with amplitude is also reduced in GO.

"Demodicosis" Mimicking PreSeptal Cellulitis: Severe Periocular and Facial Inflammation Caused by "Normal" Skin Flora.

Due to their relatively high prevalence and commensalism, the pathogenicity of Demodex mites has been debated. Recent data, however, show Demodex to be associated with skin and ocular surface diseases such as rosacea, blepharitis, and keratitis. Here the authors report the first known case, to the best of the their knowledge, of Demodex infestation mimicking preseptal cellulitis in an adult human. A 29-year-old male bilaterally blind from advanced retinopathy of prematurity presented with a 2-month history of right-greater-than-left upper eyelid and periocular/cheek swelling, redness, and ocular discharge that did not resolve with oral antibiotics or oral steroids. Based on MRI findings, biopsies of the right lacrimal gland, right orbital fat, and right upper eyelid preseptal skin were obtained which revealed marked intrafollicular Demodex mite density and budding yeasts in the upper eyelid skin. This case serves to alert clinicians to this entity that may not otherwise be usually considered in ophthalmic clinical practice.

[Clinical and morphological aspects of the use of palpebral implants made of noble metals]. / Kliniko-morfologicheskie aspekty primeneniya pal'pebral'nykh implantatov iz blagorodnykh metallov.

Loading of the upper eyelid with palpebral implants made of noble metals is the modern standard of surgical treatment for paralytic lagophthalmos, and is aimed at increasing the mobility of the upper eyelid and normalizing involuntary blinking movements. This review presents the results of morphological studies, including immunohistochemical studies, reflecting the features of biointegration of palpebral implants in uncomplicated and complicated course of the postoperative period, and describes the modern understanding of the causes and immunopathological processes underlying the development of nonspecific inflammatory response, which is one of the most serious complications that often becomes an indication for implant removal.

Meibography-Guided Electroepilation for Congenital Distichiasis: A Novel Surgical Technique.

PURPOSE: Congenital distichiasis is managed either by ablation, using laser, cryotherapy, or electroepilation, or by surgical excision with mucous membrane grafting. Ablative procedures are usually blind as the exact depth of distichiatic eyelashes is unknown. The described surgical technique utilizes meibography for imaging the root and depth of distichiatic eyelashes that aided in performing electroepilation. METHODS: Six patients (n = 24 eyelids; mean age 15.5 ± 12.2 years) underwent infrared meibography (Oculus Keratograph 5 M) and noninvasive tear breakup time prospectively. Eyelashes were electroepilated using a premarked needle inserted at a depth based on meibography findings in 4 patients. Surgical success was defined as no distichiatic eyelash regrowth and functional success was defined as the resolution of symptoms at a minimum of 3 months of follow-up. RESULTS: All 6 patients had all 4 eyelids involved to varying degrees, with a total of 230 distichiatic eyelashes. The median number of distichiatic eyelashes was 9 in the upper eyelids and 4.5 in the lower eyelids. Meibography revealed visible distichiatic eyelash roots in 70% of eyelashes in the upper eyelid and 87.8% in the lower eyelid, respectively. The median eyelash root depth was 2.7 mm (mean 2.9 mm, range 1.8-5.4 mm). The mean noninvasive tear breakup time was 12.2 seconds despite absent or rudimentary meibomian gland segments seen on meibography. The anatomical success was 75% (12/16 eyelids), and functional success was 87.5% (7/8 eyes) at a median follow-up of 5.5 months. CONCLUSION: Preoperative infrared meibography in eyelids with congenital distichiasis helps estimate the eyelash depth and can be used to guide eyelash ablation procedures.

Lid-wiper keratopathy and mucous membrane grafting.

BACKGROUND: A healthy lid-wiper is an important component of a healthy ocular surface. Any abnormality or irregularity of the lid wiper can potentially damage a relatively healthy ocular surface. Stevens-Johnson syndrome, toxic epidermal necrolysis, and ocular cicatricial pemphigoid are some of the examples that can result in lid-margin keratinization during the course of the disease. These permanent changes at the lid margin mechanically abrade the corneal surface and facilitate corneal neovascularization. The corneal clarity is lost over time, and the patients have corneal blindness. PURPOSE: This video discusses the role of a healthy lid-wiper, conditions causing lid-margin keratinization and subsequent lid-wiper keratopathy, and surgical technique in mucous membrane grafting. SYNOPSIS: The video demonstrates the technique of restoration of a healthy lid margin by doing a mucous membrane graft for lid-margin keratinization and its role in the prevention of corneal blindness. HIGHLIGHTS: Lid-margin keratinization is essentially a chronic sequela and is often ignored till irreversible corneal changes develop. Early intervention in the form of mucous membrane grafting can prevent corneal vascularization and loss of corneal clarity. VIDEO LINK: https://youtu.be/NGMlqUp_qLU.

Head rotation and the perception of eyelid height and contour.

PURPOSE: Effective visual perceptual processing is one of the many components of surgical competence. Human face identification is most efficient when viewed upright. However, it is not yet clear how this perception sensitivity impacts eyelid symmetry. This study investigates surgeons' and laypeople's accuracy and efficiency in perceiving eyelid asymmetry from different spatial perspectives. METHODS: A prospective psychometric experiment was conducted where oculoplastic surgeons were recruited from the American Society of Ophthalmic Plastic and Reconstructive Surgery and the Brazilian Oculoplastic Surgery Society, and control participants were recruited via crowdsourcing (Amazon's Mechanical Turk). Standard illustrations of the human face with varying degrees of eyelid abnormality, laterality, gender and rotation were presented to participants who were asked to judge whether the eyelids were symmetric or asymmetric. RESULTS: The survey was completed by 75 oculoplastic surgeons (49.33% male; mean age of 46.9±10.7) and 192 lay individuals (54.6% male; mean age 34.6±11.3 years). Among oculoplastic surgeons, deviation from upright was significantly associated with increased reaction time and decreased proportion correct (OR per 45° for peak 0.68, 95% CI 0.60 to 0.77, p<0.001; OR per 45° for ptosis 0.52, 95% CI 0.32 to 0.87, p=0.012; OR per 180° for aggregate responses 0.56, 95% CI 0.51 to 0.61, p<0.001). Oculoplastic surgeons demonstrated increasing accuracy and decreasing reaction time with additional trials for both peak and ptosis. CONCLUSION: Oculoplastic surgeons perceive eyelid asymmetries more accurately and can better compensate for inverted sensory information. However, accuracy increases and reaction time decreases with additional trials, suggesting trainability and potential for improvement in inversion disability.

Scleral Contact Lens to Preserve a Corneal Graft in Chronic Lagophthalmos.

Facial burns involving the periorbital region may lead to cicatricial ectropion and lagophthalmos, causing severe exposure keratopathy and eventually blindness if uncorrected. In these patients, it is critical to provide aesthetic and functional surgical correction to protect the ocular surface from chronic desiccation in addition to visual rehabilitation. Conventional methods may not be sufficient to provide visual rehabilitation in complex cases. Scleral lenses can be a multipurpose alternative for these patients. Herein, we present the challenging case of a patient who developed cicatricial lagophthalmos and exposure keratopathy after facial transplantation due to gasoline burns and received a scleral contact lens for visual rehabilitation.
