Topical insulin in neurotrophic keratopathy after diabetic vitrectomy

To assess the efficacy and safety of topical insulin (TI) for treating neurotrophic keratopathy (NK) within one-month post-diabetic vitrectomy (DV) compared to conventional non-invasive measures, we conducted this retrospective case-control study including all eyes that developed acute NK (stages 2 and 3) following DV between October 2020 and June 2023. The control group included NK cases managed with preservative-free lubricant eye drops and prophylactic topical antibiotics. In contrast, the study group included NK cases treated with TI [1 unit per drop] four times daily, in addition to the previously mentioned treatment. The primary outcome measure was time to epithelial healing. Secondary outcome measures included any adverse effect of TI or the need for amniotic membrane transplantation (AMT). During the study period, 19 patients with a mean age of 49.3 ± 8.6 years received TI versus 18 controls with a mean age of 52.5 ± 10.7 years. Corneal epithelial healing was significantly faster in the TI-treated group compared to controls, with a mean difference of 12.16 days (95% CI 6.1–18.3, P = 0.001). Survival analysis indicated that the insulin-treated group had 0% and 20% of NK stages 2 and 3, respectively, that failed to achieve corneal epithelial healing, compared to 20% and 66.7% for the control group (P < 0.001). In the control group, two eyes required AMT due to progressive thinning. Additionally, three patients in the control group, progressing to stage 3 NK, were switched to TI, achieving healing after a mean of 14 days. No adverse effects were reported in the TI-treated group. Our study suggests that TI can effectively and safely promote the healing of NK after DV.

The outcomes of corneal sight rehabilitating surgery in Stevens-Johnson syndrome: case series

PurposeTo summarize the outcomes of corneal sight rehabilitating surgery in Stevens-Johnson syndrome (SJS).MethodsThis is a retrospective analysis of a consecutive case series. Twenty-four eyes of 18 SJS patients were included in this study. The ocular parameters, surgical procedures, postoperative complications, and additional treatments of the cases were reviewed.ResultsA total of 29 corneal sight rehabilitating surgeries, which consists of 9 keratoplasties, 8 Keratolimbal allograft (KLAL) and 12 combined surgeries (keratoplasty and KLAL simultaneously) were performed on the 24 eyes. All patients were treated with glucocorticoid eyedrops and tacrolimus eyedrops for anti-rejection treatment without combining systemic immunosuppression, except two patients who were prescribed prednisone tablets for the management of systemic conditions. The mean follow-up period was 50.6 ± 28.1 months. The optimal visual acuity (VA) (0.74 ± 0.60 logarithm of the minimum angle of resolution [logMAR]) and endpoint VA (1.06 ± 0.82 logMAR) were both significantly better than the preoperative VA (1.96 ± 0.43 logMAR) (95% CI, p = 0.000). 57.1% patients (8/14) were no longer in the low vision spectrum, and 88.9% patients (8/9) were no longer blind. The mean epithelialization time was 7.1 ± 7.6 weeks. The success rate was 86.7%. Additional treatments for improving epithelialization included administration of serum eyedrops (n = 10), contact lens (n = 15), amniotic membrane transplantation (n = 6), and tarsorrhaphy (n = 8). Complications included delayed epithelialization (n = 4, over 12 weeks), glaucoma (n = 11), and severe allograft opacity (n = 4). Only one graft rejection was observed.ConclusionsKeratoplasty and KLAL can remarkably enhance VA and improve low vision or even eliminate blindness for ocular complications of SJS. The outcome of the surgeries was correlated with the preoperative ocular situation and choice of operative methods.

Clinical features and comprehensive treatment of persistent corneal epithelial dysfunction after cataract surgery

ObjectiveEvaluation of clinical efficacy and safety of tobramycin/dexamethasone eye ointment in treating persistent corneal epithelial dysfunction (PED) after cataract surgery.Methods26 cases diagnosed as PED after cataract surgery accept the tobramycin/dexamethasone ophthalmic ointment and intense pulse light treatment in the Xiamen University of Xiamen eye center between September 2016 and April 2022 were retrospectively analyzed, mainly including clinical manifestations, characteristics of morphological changes imaged by in vivo confocal microscopy, meibomian glands infrared photography, lipid layer thickness (LLT), management and therapeutic effects.ResultsThere were 26 eyes, include 8(35%) males and 15(65%) females with an average age of 69.6 ± 5.2 years(50 to 78 years). The mean hospitalization time was (18.4 ± 7.5) days after cataract surgery. Twenty patients had meibomian gland dysfunction. Infrared photography revealed varying loss in the meibomian glands, with a mean score of 3.8 ± 1.2 for gland loss. The mean LLT was 61.6 ± 8.4 nm. After treatment, 20 patients were cured, and 3 received amniotic membrane transplantation. After treatment, the uncorrected visual acuity (UCVA) and best-corrected vision activity (BCVA) improved (P < 0.001), and there was no significant difference in intraocular pressure (IOP) before and after treatment (P > 0.05).ConclusionsThe early manifestation of PED after surgery is punctate staining of the corneal epithelium. Tobramycin and dexamethasone eye ointment bandages have a good repair effect. The meibomian gland massage combined with intense pulse light treatment can effectively shorten the course of the disease.

How does atmospheric pressure cold helium plasma affect the biomechanical behaviour on alkali-lesioned corneas?

BackgroundMelting corneal ulcers are a serious condition that affects a great number of animals and people around the world and it is characterised by a progressive weakening of the tissue leading to possible severe ophthalmic complications, such as visual impairment or blindness. This disease is routinely treated with medical therapy and keratoplasty, and recently also with alternative regenerative therapies, such as cross-linking, amniotic membrane transplant, and laser. Plasma medicine is another recent example of regenerative treatment that showed promising results in reducing the microbial load of corneal tissue together with maintaining its cellular vitality. Since the effect of helium plasma application on corneal mechanical viscoelasticity has not yet been investigated, the aim of this study is first to evaluate it on ex vivo porcine corneas for different exposition times and then to compare the results with previous data on cross-linking treatment.Results94 ex vivo porcine corneas divided into 16 populations (healthy or injured, fresh or cultured and treated or not with plasma or cross-linking) were analysed. For each population, a biomechanical analysis was performed by uniaxial stress-relaxation tests, and a statistical analysis was carried out considering the characteristic mechanical parameters. In terms of equilibrium normalised stress, no statistically significant difference resulted when the healthy corneas were compared with lesioned plasma-treated ones, independently of treatment time, contrary to what was obtained about the cross-linking treated corneas which exhibited more intense relaxation phenomena.ConclusionsIn this study, the influence of the Helium plasma treatment was observed on the viscoelasticity of porcine corneas ex vivo, by restoring in lesioned tissue a degree of relaxation similar to the one of the native tissue, even after only 2 min of application. Therefore, the obtained results suggest that plasma treatment is a promising new regenerative ophthalmic therapy for melting corneal ulcers, laying the groundwork for further studies to correlate the mechanical findings with corneal histology and ultrastructural anatomy after plasma treatment.

Histopathological and statistical study of corneal repair in rabbits. A new way to understand corneal recovery.

The study aims to evaluate corneal healing post amniotic membrane transplantation in controlled corneal defects, justifying its application in routine ophthalmology practice. The objective is to establish a reliable method for assessing the repair process. In three groups of six adult New Zealand rabbits, keratectomy and a monolayer transplant of dehydrated human amniotic membrane (AM) were conducted in the left eye (OS) with the right eye (OD) serving as the control eye. Clinical signs were assessed, and both eyes were enucleated at 1, 2, and 4 weeks for optical coherence tomography (OCT) measurements and histological analysis, collecting data from different epithelium, stroma, and limbus regions. This study was conducted using a formula that combines histologic data categorizing their presence and/or type as beneficial for corneal repair. No statistically significant differences were found between the experimental and control eyes regarding all clinical signs and OCT measurements. However, a linear model using histopathological results showed a period-implant mode interaction with statistical significance (p=0.010). The use of the single-layer amniotic membrane resulted in improved corneal recovery with the stromal side showing better performance in the first week and the epithelial side proving to be more effective than the stromal side in the long term. For the first time, a statistical formula employing histopathological data is introduced to determine corneal recovery, potentially offering a more accurate and reliable method compared with the observation of clinical signs and corneal measurements with OCT.

AN ATYPICAL CASE OF BILATERAL CORNEAL OPACITY: WHAT ARE THE POSSIBLE DIAGNOSIS?

Introduction: Corneal opacity can be divided into inflammatory and noninflammatory entities. The clinical presentation and characteristics of a corneal opacity can often help reach a diagnosis. However, atypical cases are more challenging to diagnose. This report aims to explore an atypical case of corneal opacity and the diagnostic approach through its clinical presentation. Case Report: A thirty-seven-year-old female patient had a chief complaint of gradual blurry vision in both eyes and slowly growing whitish lesions one year prior. The patient recalled a history of bilateral eye redness two years ago. The anterior segment examination and AS-OCT revealed bilateral, smooth, oedematous pearly-white elevated opacity with well-demarcated margins at the center of the cornea, with epithelial depth. The diagnosis of corneal keloid was favored, with GDLD and SND as the differential diagnosis. In local anesthesia, the patient underwent superficial keratectomy and amniotic membrane transplantation of the right eye. On one month follow-up, the patient felt an improvement in her subjective complaints with a normal appearance of the cornea. Discussion: The atypical characteristics found in our case didn’t fit a single mold, as it shared features of post- injury hypertrophic scar, degenerative, and dystrophy. We diagnosed the patient with corneal keloid caused by suspicion of subclinical infection. Although GDLD and SND were still possible, the working diagnosis was enough to warrant a therapeutic surgical removal. Conclusion: Atypical presentations make diagnosis more challenging. However, despite improvements in diagnostic modalities, signs, and symptoms remain very helpful in reaching a working diagnosis.

Acellular human amniotic membrane: A safe and stable matrix for corneal stromal regeneration

Amniotic membrane (AM) transplantation is used as a safe and effective method to treat a variety of ocular complications. On the ocular surface, this membrane degrades within a few days. This study investigated the safety and long-term stability of human amniotic membrane (HAM) grafts in the corneal stroma. Three rabbits with healthy eyes underwent unilateral stromal pocketing with implantation of decellularized HAM (dHAM). Examinations of graft bio-integration were performed by corneal imaging using slit lamp and optical coherence tomography (OCT) at 1 week, 3 months, and 9 months. The thickness of the thickest part of the amniotic membrane was 187 μm at the first follow-up, 184 μm at 3 months, and 166 μm at 9 months. Histological evaluation was performed after the last follow-up. The results showed no clinical complications, such as opacity, neovascularization, infection, or rejection. The thickness of the grafts remained stable over time. Histopathological analyses showed the grafts were integrated into the corneal stroma without any inflammation. This study indicated that HAM was a naturally safe, stable, and compatible matrix in the corneal stroma and was considered a promising candidate for corneal stromal regeneration.

Clinical Characteristics and Treatment of Ophthalmic Sequelae of Stevens-Johnson Syndrome and Toxic Epidermal Necrolysis at a Tertiary Eyecare Centre in Hungary.

This study analysed the causative factors and clinical characteristics of acute and chronic ocular sequelae of Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) treated at a large third-referral centre in a developed country (Hungary) over a 15-year period. This was a retrospective review of patients with acute and/or chronic SJS/TEN who were managed between 2006 and 2020 at the Department of Ophthalmology of Semmelweis University in Budapest, Hungary. For each subject, clinical data, including patient demographics, clinical history, causative agents of SJS/TEN, and conservative and surgical treatment details, were reviewed. Ninety-six eyes of 48 patients were included (28 female; 58.3%); the age at disease onset was 32.1 ± 22.4years. The most common causative factors were medicines (n = 36; 75.0%). Among these drugs, 29.2% were nonsteroidal anti-inflammatory drugs (NSAIDs) (n = 14), 20.8% were antibiotics (n = 10) and 14.6% were antiepileptic drugs (n = 7). In patients with chronic SJS/TEN, the most commonly found ocular sequelae were conjunctival hyperaemia in 45 (56.3%) eyes, symblepharon in 38 (47.5%) eyes, trichiasis/distichiasis in 37 (46.3%) eyes, corneal neovascularization in 31 (38.8%) eyes and corneal scarring in 29 (36.3%) eyes. In patients with chronic SJS/TEN, the most frequently used topical conservative treatment included antibiotics in 53 (66.3%) eyes, preservative-free artificial tears in 50 (62.5%) eyes and topical corticosteroids in 42 (52.5%) eyes of 40 patients. The most frequently performed ocular surgeries for managing chronic ocular sequelae in patients with SJS/TEN were epilation for trichiasis (n = 27; 33.8%), cataract surgery (n = 14; 17.5%), entropion surgery (n = 12; 15.0%), penetrating keratoplasty (PK) (n = 11; 13.8%) and amniotic membrane transplantation (n = 4; 5.0%). Our results suggest that NSAIDs, antibiotics and antiepileptic drugs are the most common causative factors for SJS/TEN in Hungary. Like in other countries, in Hungary, the ocular management of patients with acute and chronic SJS/TEN is heterogeneous, and most cases do not follow modern therapeutic guidelines.

Modified mini-SLET for treatment of complex cases in pterygium surgery

The major problem associated with the benign but destructive growing pterygium is the high recurrence rate. Anew surgical technique to lower recurrence rates is minor ipsilateral simple limbal epithelial transplantation (mini-SLET), where the regeneration potential of limbal stem cells is used in combination with amniotic membrane transplantation (AMT) for surgical reconstruction. The aim of this study is to assess the surgical outcome of the mini-SLET technique with tenonectomy, mitomycinC, and AMT as used in the authors' hospital. Atotal of 16eyes from 15patients undergoing mini-SLET after surgical pterygium removal with tenonectomy, mitomycinC, and AMT were analyzed retrospectively. Two different groups of pterygia were enrolled: group1 included recurrent pterygia (n = 10) and group2 comprised primary large pterygia such as double-head pterygia (n = 6). In addition to assessment of best corrected visual acuity and compete ophthalmological examination, preoperative slip-lamp examination with photo documentation served to calculate the corneal size of the pterygium head using VISUPAC software (Zeiss, Oberkochen, Germany). Postoperatively, best corrected visual acuity and slit-lamp examination were routinely evaluated. The surgical outcome was defined by the postoperatively achieved best corrected visual acuity, restoration of the ocular surface, recurrence rate, and rate of postoperative complications. Median follow-up in all patients was 27months; in groups1 and 2 it was 30.7and 25.3months, respectively. No recurrence developed in 15eyes (93.75%). Only one group1 patient (6.25%) suffered arecurrent lesion after 10months. Postoperatively, logMAR visual acuity did not change significantly. During follow-up, complications were limited to one case of early wound dehiscence. Mini-SLET in combination with tenonectomy, mitomycinC, and AMT enables good surgical reconstruction of the ocular surface, and almost complete healing in the sense of restitutio ad integrum is possible. The results of the present study have shown the technique's effectiveness for recurrence prevention.

Amniotic membrane transplantation for ocular surface burns

Amniotic membrane transplantation for ocular surface burns

Correlation Between the Cost and Safety of Corneal Graft Types.

Background Corneal diseases are the fourth most common cause of blindness worldwide. In the majority of these diseases, vision reduction is reversible and can be restored to a large extent by replacing the cornea through specific surgery and, in particular, transplantation. In Greece, due to a lack of organized eye banks as well as donors, the grafts intended for corneal transplantation usually come from eye banks abroad. This study focuses on the dynamics of cost versus value in the decision-making process for the procurement of corneal grafts, ultimately investigating the safety that the procured grafts provide to patients. Methodology A total of 267 patients with severe vision problems who underwent 301 corneal and amniotic membrane transplants from years 2020 to 2023 at the Transplant Unit of the Athens General Hospital "Georgios Gennimatas" were included in this study. All patients who were deemed appropriate to undergo corneal transplant operations, the diagnosis that led to the specific surgery, and other relevant data were recorded and evaluated. Results There was no significant difference in the ratio between males and females (51.3% male and 48.7% female). The mean age of the patients was 66.5 years (SD = 13.7 years). Graft problems were faced by 13.9% of the patients, with the amniotic membrane by 1.5% (in the total number of surgical operations) and both eyes by 4.5% of patients. The majority of the patients had undergone only one surgery (88.8%). Reoperation was needed in 14% of the cases, and 7.6% of the cases were surgeries that occurred due to graft rejection or non-functioning grafts from surgeries performed at another hospital or clinic. In the majority of surgeries (60.8%), a Descemet's stripping automated endothelial keratoplasty graft was used. The mean cost was 3,167 euro (SD = 960.3 euro). Furthermore, in 35.8% of the surgeries, the graft was preserved with amphotericin. Conclusions The present study draws useful conclusions about the effectiveness of surgical interventions through the correlation of cost and safety of the grafts that are approved and finally used in corneal transplants, as well as the submission of proposals to improve the procedures and lead to patient benefits.

Clinical Outcomes and Indications of In-Office Sutureless Dried Gamma Ray-Sterilized Human Amniotic Membrane Transplantation With Bandage Contact Lenses in Various Ocular Surface Disorders.

The purpose of this study was to investigate the efficacy and indications of using dried gamma ray-sterilized amniotic membrane (AM) transplantation with bandage contact lenses for the in-office sutureless treatment of various ocular surface diseases. This study retrospectively included 56 eyes of 52 patients with various ocular surface diseases treated with sutureless dehydrated AM-assisted therapeutic contact lenses. The patients were followed up and assessed 1, 2, and 4 weeks after the treatment, and the therapeutic contact lenses were removed after 1 or 2 weeks. The size of the corneal lesion and the degree of pain experienced by each patient before and after the procedure were measured. Corneal re-epithelization rate and clinical aspects related to re-epithelialization were evaluated. Complete corneal re-epithelialization of the epithelial defect was observed in 40 eyes. The complete re-epithelialization rates of persistent epithelial defect caused by infectious ulcers, neurotrophic ulcers, ulcers due to burn, toxic keratopathy, previous penetrating keratoplasty or other corneal surgeries, and severe dry eye disease were 69.2%, 80.0%, 77.8%, 100%, 75.0%, and 100%, respectively. Five patients with uncontrolled infectious ulcers, neurotrophic ulcer, bullous keratopathy, and ulcers associated with rheumatic disease did not show significant improvement. Patient pain scores significantly decreased after the procedure. Dehydrated AM transplantation with a bandage contact lens is minimally invasive and easily applicable through in-office procedures. This approach is expected to be more actively applied in various ocular surface disorders, not only in severe corneal diseases but also in relatively mild corneal surface diseases.

Combination Therapy of Amniotic Membrane Transplantation with Conjunctival Peritomy and Autologous Serum for Mooren's Ulcer: A Case Report

Introduction : A case report of a patient with Mooren’s ulcer who received partial amniotic membrane transplantation and autologous serum eye drops.&#x0D; Case Illustration : A 44-year-old male patient presented with chief complaint of blurred vision, pain in left eye, and history of eye trauma 6 months prior. Empirical topical antibiotics didn’t improve his condition. VA of left eye was hand movement with good colour/light perception. We diagnosed the patient with marginal ulcer. Partial amniotic membrane transplantation with conjunctival peritomy was planned for this patient along with fortified antibiotic eye drops. Autologous serum eye drops were started at 2 weeks post-surgery. 2 months after surgery, his condition has significantly improved with visual acuity of 6/12 (Snellen), healed corneal defect, and subjective relief of symptoms.&#x0D; Discussion : Mooren’s ulcer is a severe ulcerative inflammation of the cornea with unclear exact pathogenesis. Many therapies of Mooren’s ulcer are recommended in literatures, including surgical and non- surgical treatment. It was reported that amniotic membrane transplantation and conjunctival peritomy may be chosen as alternative surgical procedure for Mooren’s ulcer, as peritomy displaces the source of inflammation away from the cornea and amniotic membrane helps in corneal reepithelialization. Autologous serum is considered as an effective adjuvant therapy for ocular surface diseases such as dry eye disease, cicatricial pemphigoid, Steven-Johnson syndrome, and Mooren’s ulcer—thus the decision to include the therapy in our regiment.&#x0D; Conclusion : The combination of amniotic membrane transplantation, conjunctival peritomy, and autologous serum may help in the overall improvement of patients with Mooren’s ulcer.

Amnion Membrane Transplantation: A Therapy for Persistent Epithelial Defect as A Result of Neurotrophic Keratitis

Introduction : A persistent epithelial defect (PED) is a failure of re-epithelialization and complete healing of the cornea. The primary goal of PED treatment is to create a favorable environment for corneal wound healing. Amniotic membrane transplants (AMT) become one of the refractory cases treated for PED. This study aims to report AMT as therapy for a PED.&#x0D; Case Illustration : A fifty-six-year-old male presents with a chief complaint of redness and pain in the left eye in the last2 weeks. The patient complained of blurred vision, tearing, and foreign body sensations. An ophthalmology examination of the left eye revealed that it was close to face finger counting in visual acuity and had a persistent epithelial defect, corneal edema, descemet fold, and a decrease in corneal sensation. The patient was diagnosed with PED and received autologous serum eye drops, levofloxacin eye drops, vitamin A palmitate eye gel, and acyclovir 400mg twice a day, but did not respond adequately. AMT was planned for the patient. The patient's pain level improved one week after surgery.&#x0D; Discussion : The most common symptom of PED is pain. There are various etiological factors for PED. Neurotropic keratitis has emerged as one of the causes of PED. Management for PED is carried out sequentially according to the protocol.&#x0D; Conclusion : Amniotic membrane transplantation has become an alternative therapy for PED. The amniotic membrane provides re-epithelialization of the cornea and anti-inflammatory properties. The prognosis for AMT as a therapy for PED is quite good.

Combination of Superficial Keratectomy, Ethylenediaminetetraacetic (EDTA), and Amniotic Membrane Transplantation as A Treatment of Band keratopathy: A Case Report

Introduction : Band keratopathy is a degeneration of the cornea characterized by the presence of opacity, which isa deposit of calcium hydroxyapatite. These calcium deposits can be removed in several ways, including using ethylenediaminetetraacetic (EDTA), superficial keratectomy, or phototherapy keratectomy.&#x0D; Case Illustration : A 29-year-old male patient came with complaints of blurry vision in the right eye since 2-3 years ago, accompanied by the middle part of both eyes looking white, especially the right eye, since 17 years ago. The examination revealed a band keratopathy in the nasal to temporal region with neovascularization in the right eye, and keratopathy bands in the nasal and temporal parts, as wellas a cloudy lens in the right eye (Figure 1). Patients received treatment that included a combination of superficial keratectomy, administration of EDTA, and amniotic membrane transplantation (Figure 2). After the procedure, the clarity of the cornea improves (Figure 3). The patient was scheduled to undergo cataract surgery on his right eye.&#x0D; Discussion : Band keratopathy is a degenerative condition of the cornea characterized by grayish-white hazy deposits in the superficial layers of the cornea, primarily affecting Bowman's layer. In the treatment of individuals with symptomatic band keratopathy, chelation with EDTA, superficial keratectomy, laser keratectomy for phototherapy, or combining current procedures are the most often utilized therapeutic approaches.&#x0D; Conclusion : The combination of surgical management in cases of band keratopathy is expected to remove deposits on the cornea, improve the ocular surface, and reduce recurrences.

Pseudopterygium After Limbal Dermoid Cyst Excision in a Child with Goldenhar Syndrome

Introduction : Goldenhar syndrome is a rare congenital disorder also known as oculoauricularvertebral dysplasia. Limbal dermoid associated with this syndrome. This case report aims to present an reccurent pseudopterygium after three times limbal dermoid cyst excision in patient with Goldenhar syndrome.&#x0D; Case Illustration : Patient 13 years old male with pseudopterygium in right eye. Visual acuity both eyes 6/6 snellen chart. Fibrovascular tissue from tarsal conjunctival inferotemporal to 2 mm limbal cornea in right eye. Patient had limbal dermoid cyst in right eye since birth and underwent limbal dermoid cyst excision for three times. First time surgery used amniotic membrane transplantation, then second and third surgery used conjunctival limbal graft. Goldenhar syndrome have been diagnosed since the age of 2 years old. External examination noticed asymmetrical hemifacial microsmia, grade III microtia right ear, conduction deafness, and laryngomalacia.&#x0D; Discussion : Limbal dermoid cyst is one of characteristic of Goldenhar syndrome. In this case pseudopterygium grade II in right eye developed after limbal dermoid cyst excision for three times. Limbal dermoid simple excision may lead to corneal vascularization persistent epithelial defect, scar, and pseudopterygium. Various surgical include superficial keratectomy, amniotic membrane transplantation and lamellar or penetrating keratoplasty. Pseudopterygium still occurs in this case, even though recurrence has been prevented by administration of amniotic membrane transplantation and conjunctival limbal graft.&#x0D; Conclusion : We should be concerned about management of limbal dermoid cyst with Goldenhar syndrome to prevent recurrent pseudopterygium.

Tenon Patch Graft in The Management of Corneal Perforations: A case series

Introduction : A full-thickness defect of the cornea that results in a rupture or opening is known as corneal perforation. Despite corneal transplant being the gold standard therapy, finding a donor remains challenging. Tenon patch graft (TPG) may be the alternative surgical procedure to repair the damaged cornea. This case series presents six cases of corneal perforations that have been effectively managed with TPG.&#x0D; Case Illustration : Six cases with corneal perforations in the age range of 6-75 years old were presented with varying perforation sizes ranging from 0.5 to 8 mm. The most common complaints were vision loss, redness, and watery eyes. Ophthalmology examinations revealed five corneal ruptures and one impending corneal rupture caused by trauma, infections, corpus alienum, and post-operative. All patients underwent TPG surgery with compression/infinity sutures using 10-0 nylon, followed by bandage contact lenses, with three adjoined with amniotic membrane transplant. Post TPG, patients were followed up for 1-4 months and no complications such as glaucoma, cataract, or endophthalmitis were found.&#x0D; Discussion : Corneal damage that is not treated promptly causes further erosion of the deeper corneal layers. When medication fails, other measures must be taken to preclude further damage. TPG may be an accessible and cost-effective surgical procedure of choice to preserve eye integrity both functionally and structurally.&#x0D; Conclusion : This case series of tenon patch grafts for corneal perforations less than 9 mm demonstrated the effectiveness of TPG in promoting corneal healing without significant complications. Despite differences in perforation size and patient characteristics, all six cases saw closure of the perforation.

PEDIATRIC BLEPHAROKERATOCONJUNCTIVITIS WITH DESCEMETOCELE AND CORNEAL NEOVASCULARIZATION : A CASE REPORT

Introduction : Blepharokeratoconjunctivitis is a chronic and recurrent inflammatory eyelid disorder that is commonly associated with secondary conjunctival and corneal involvement that is frequently underdiagnosed in children. The objective is to report a descemetocele and corneal neovascularization as severe complications of blepharokeratoconjunctivitis in children.&#x0D; Case Illustration : A five years old girl complained blackish lump in the right eye since a month ago. She also had a whitish spot in her eye since a year ago with redness, glare and watery. Three years ago she had a lump in the right eyelid and eye redness intermittently that was getting better with eye drop and history of allergy of house dust mites. Visual acuity (VA) in right eye was hand movement. Anterior segment of the right eye showed telangiectasis of palpebra, hyperemic conjunctiva, with neovascularization of entire surface of the cornea, descemetocele, leucoma and corneal thinning around descemetocele. We injected subconjunctival anti-vascular endothelial growth factor (VEGF) injection then we performed amniotic membrane transplantation. Follow-up 2 months post surgery we found VA was 2 m counting finger and the corneal neovascularization was reduced.&#x0D; Discussion : This case represents severe blepharokeratoconjunctivitis can cause some complications, from this patient we found corneal neovascularization and descemetocele. Anti-VEGF injection was to inhibit new blood formation in the patient’s cornea and the amniotic membrane transplantation was to manage the descemetocele.&#x0D; Conclusion : Pediatric blepharokeratoconjunctivitis and the complications associated with its treatment can be sight threatening. Early recognition of this disease entity and adequate management may arrest the disease process and may minimize visual morbidity.
