RESUMO

BACKGROUND: Limited studies have reported surgical outcomes that are defined by strict criteria following grade 2 or 3 socket reconstruction using an oral mucosal graft (OMG). We aimed to determine factors influencing surgical outcomes of anophthalmic socket reconstruction using OMG in patients with grade 2 or 3 socket contractures. METHODS: Thirty-seven patients who underwent socket reconstruction with autologous OMG between January 2007 and December 2017 were retrospectively analyzed. The successful outcome was defined as an eye prosthesis wearing without experiencing displacement and the absence of any re-operations or additional surgeries following socket reconstruction. Factors affecting surgical outcomes were identified using multivariate analysis. RESULTS: A total of 15 male and 22 female patients (mean age: 40.2 ± 17.2 years) were included. The median duration of socket contracture was 21.5 years. Grade 2 and 3 socket contractures, based on Tawfik's classification, were reported in 20 and 17 patients, respectively. Twenty-eight and eight patients underwent socket reconstruction using OMG alone and OMG combined with a hard palate graft, respectively. The success rates of grades 2 and 3 socket contracture reconstruction were 80.0% and 52.9%, respectively. Multivariate analysis demonstrated that only grade 3 contractures were predictive of worse outcomes. At the final visit (mean follow-up: 6.3 years), 34 patients (91.9%) could wear their eye prostheses. CONCLUSIONS: Socket reconstruction using autologous OMG can provide acceptable results in grade 2 and 3 contractures; however, satisfactory results were more significantly reported in grade 2 than in grade 3 contractures.

RESUMO

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.

RESUMO

PURPOSE: To compare tear film osmolarity (TFO) values and matrix metalloproteinase 9 (MMP-9) levels between anophthalmic sockets and healthy fellow eyes and to assess the use of the MMP-9 and TFO as objective biomarkers for the dry anophthalmic socket syndrome (DASS). METHODS: In this prospective single-center study, the anophthalmic sockets and healthy fellow eyes of 98 unilateral anophthalmic patients were assessed using the ocular surface disease index (OSDI) questionnaire, InflammaDry® MMP-9 point-of-care immunoassay, TFO with TearLab™ Osmolarity System, and clinical conjunctival inflammation. MMP-9 concentration and conjunctival inflammation were graded semi-quantitatively. Differences between anophthalmic sockets and the healthy fellow eyes for OSDI scores, MMP-9, TFO values, clinical conjunctival inflammation, and eyelid abnormalities as well as the correlation between these factors and demographic data were evaluated. RESULTS: Patients had significantly higher OSDI, MMP-9, and TFO values, as well as higher conjunctival inflammation on the anophthalmic side, compared to the healthy side (p ≤ 0.002, respectively). For anophthalmic sockets, there was a significant positive correlation between OSDI scores and TFO values (p = 0.007), between the grade of posterior blepharitis and TFO values (p = 0.026), and between the conjunctival inflammation and MMP-9 values (p < 0.001), as well as between MMP-9 levels and time since eye loss (p = 0.004). CONCLUSIONS: Measuring MMP-9 and TFO may be helpful tools as efficient, quantifiable biomarkers, disease course parameters, or predictors for treatment response in the clinical management of patients with DASS or future therapy studies. Ophthalmologists should consider the updated diagnosis criteria including TFO and the definition for DASS proposed in this study.

RESUMO

Ocular prostheses are liable to host microbial adhesion, which can favor conjunctival inflammation. Knowing the microbiota of the ocular prosthesis and anophthalmic socket is important for predicting infection-related pathogens. This study evaluated the microbiota of the prostheses and anophthalmic sockets of six individuals by 16S rRNA sequencing. The microbial abundance and diversity were analyzed using the Operational Taxonomic Units at the genus level. Forty-seven phyla, capturing 1,258 named genera, were recorded in the sample set. In both sites, the most frequent genera were Fusobacterium, Staphylococcus, Prevotella, and Streptococcus. The microbial abundance was higher for the anophthalmic socket than for the prosthesis. Alpha diversity showed no significant differences in bacterial richness or diversity between sites. Although the microbial abundance in the anophthalmic socket was higher, both sites had similar microbiota with high diversity and low dominance among the genera.

RESUMO

A 67-year-old Caucasian male presented with severe contraction of socket lining 8 years after enucleation, dermis fat graft and successful ocular prosthesis fitting. Following two failed attempts at using amniotic membrane grafts to reform the socket lining, a total socket reconstruction was attempted using a novel nasal turbinate mucosal graft technique. This was performed in a staged fashion with lower fornix reconstruction followed by upper fornix reconstruction 3 months later. The patient was stable at 12 months review, with a satisfactory cosmetic outcome. Nasal turbinate mucosa was used as it was surgically accessible, provided natural socket lubrication due to its mucosal surface, and avoided oral mucosa and its associated morbidity. This case report suggests that nasal turbinate mucosa is a suitable autologous grafting material for total socket reconstruction in contracted anophthalmic sockets.

RESUMO

PURPOSE: To analyse the ocularist's perspective on the management of the anophthalmic socket and external ocular prosthesis (EOP). METHODS: Ocularists from two countries were invited to participate in an online questionnaire. Data were collected on demographics, anophthalmic socket and EOP management (manufacturing, use, cleaning), complications, follow-up visits and multidisciplinary care. The frequency and proportions of the responses were statistically analysed. RESULTS: The questionnaire was addressed to 20 Brazilian and 17 Spanish ocularists, obtaining a response rate of 65% and 64.7%, respectively. 62.5% of respondents were men. The most common cause of anophthalmia in Brazil (69.2%) and Spain (36.4%) is an eye disease (chi square: p = 0.188). Polymethylmethacrylate (PMMA) is the most commonly used material in EOP manufacture (chi square: p = 0.448), and 70.8% reported using customized EOPs (chi square: p = 0.069). Deposits are frequently observed in both countries (chi square: p = 0.157). Changing the prosthesis is recommended after 5 to 10 years by Brazilian ocularists, and after less than 5 years of use by Spanish ocularists (81.8%) (chi square: p = 0.041). Annual follow-up is recommended by Spanish ocularists (45.5%), while semestral (38.5%) and case-dependent (38.5%) follow-up is recommended by Brazilian ocularists (chi square: p = 0.267). Daily cleaning is advocated by 61.5% of Brazilian ocularists and once a month by 45.5% of Spanish ocularists (chi square: p = 0.098), with 75% of ocularists from both countries not recommending EOP removal at night (Fisher´s exact test: p = 0.166). Good communication between ocularists and ophthalmologists was reported by 87.5% of our responders (chi square: p = 0.642). CONCLUSION: Although there are no unified protocols on the management of EOPs, Brazilian and Spanish ocularists follow similar guidelines. Differences between countries were the patients´ referral and the prosthesis´ useful life.

RESUMO

BACKGROUND: The last definition of the post-enucleation socket syndrome (PESS) by Tyers and Collin-formulated almost 40 years ago in 1982-is predominantly based on the clinical characteristics and does not include the insights of newer studies into the pathophysiological mechanism of the PESS. METHODS: A systematic PubMed literature review regarding the pathophysiological mechanism of the PESS was performed, and results were comprised to give an overview of the current knowledge of the PESS including the exact pathophysiological mechanism. RESULTS: The primarily postulated pathophysiological mechanism of the PESS was the atrophy of orbital tissues, especially of fat, resulting in variable clinical findings. Newer studies using high-resolution computed tomography and magnetic resonance imaging or performing histopathological analyses found no orbital fat atrophy but rather a rotatory displacement of the orbital tissues from superior to posterior and from posterior to inferior together with the retraction of the extraocular muscles and a possible volume loss of the orbital implant by resorption if it is manufactured from hydroxyapatite. PESS results in a backward tilt of the superior fornix, a deep superior sulcus, a pseudo-ptosis, a lower eyelid elongation and laxity, a shallower inferior fornix, as well as enophthalmos and may lead to an inability of wearing ocular prostheses. CONCLUSIONS: A novel and comprehensive definition of the PESS is proposed: PESS is a multifactorial and variable syndrome caused by a rotatory displacement of orbital contents together with the retraction of the extraocular muscles and possible resorption of the orbital implant if it is manufactured from hydroxyapatite.

RESUMO

PURPOSE: To evaluate the amplitude of movement in anophthalmic sockets reconstructed with conical or spherical orbital implants with and without an external ocular prosthesis (EOP), and whether the fornix depth could play a role. METHODS: Prospective observational study involving unilateral anophthalmic sockets evaluated the amplitude of movement with conical (20 subjects) or spherical (16) non-porous orbital implants, with and without an EOP, having the contralateral eye as the control group. Standardized photographs were obtained in the four gaze directions and measurements were performed using the Image J software. The upper and lower fornix depths were measured using rulers. RESULTS: Compared to the contralateral eye, the median movement amplitude without EOP was smaller with conical implants in supraduction (-0.88 mm, p=0.008), abduction (-2.26 mm, p<0.001) and adduction (-0.91 mm, p=0.008). Spherical implants had reduced movement only in abduction (-2.63 mm, p<0.001). Conical and spherical implants had similar amplitudes of movement in all versions, and were always smaller compared to the control. The median movement amplitude with the EOP was -3.05 mm (p=0.001) than without the EOP in abduction and -2.07 mm (p=0.020) in adduction, regardless of implant format. The fornix depth did not affect the orbital implants or EOP movement amplitude's median. CONCLUSION: Conical and spherical implants provide similar amplitude of movement and fornix depth did not have an influence on it. The amplitude of movement was significantly limited compared to the contralateral eye and was even more reduced if the EOP was in place with conical or spherical implant formats.

RESUMO

Purpose: To report the outcomes of a survey on patients' concerns and satisfaction with custom ocular prosthesis (COP) wear and compare with objective clinician grading scales.Methods: The questionnaire was answered by 156 participants. General social concerns and prosthesis-related concerns were plotted on a scale of 0 to 10, indicating least to maximum satisfaction and also not concerned to very concerned. Comparison between subjective patient and objective clinician scores was done.Results: The mean age at presentation was 27.53 ± 15.53 years (range 3-72 years).For patients that underwent a prior surgical procedure, mean satisfaction with the surgery was 9.42 ± 1.27. Mean satisfaction with the COP was 8.98 ± 1.75. The median satisfaction score for the primary surgery as well as for the outcome of the custom ocular prosthesis was 10. Commonest prosthesis-related concerns were reduced motility (mean 3 ± 2, median 3), watering, crusting and discharge (mean 2 ± 2, median 2), and difference in the size of the prosthetic eye relative to the other eye (mean 1 ± 2, median 1). Subjective patient concern responses and the objective clinician grading correlated strongly for movement of the prosthesis (r = -0.84, p < .0001), periocular fullness (r = 0.65, p < .0001), color of the prosthesis (r = -0.8, p < .0001) and size relative to the other eye (r = 0.7, p < .0001).Conclusion: Custom ocular prosthesis usage had a high satisfaction score with minimal concerns. Commonest prosthesis-related concerns correlated strongly with objective clinician grading.

RESUMO

OBJECTIVES: To evaluate the outcomes of secondary autologous dermis-fat graft as an orbital implant in anophthalmic sockets. METHODS: In this prospective study, which was conducted at Jinnah Post Graduate Medical Centre, Karachi, between January 2015 and January 2020, we evaluated 12 patients between the ages of four and 60 years. Most of the adults were victims of trauma, whereas children were known cases of retinoblastoma or trauma and all underwent enucleation. All of them were primarily treated elsewhere and not offered primary orbital implants. We performed autologous dermis-fat graft as an orbital implant in these patients harvesting graft from gluteal region and followed them up to look for complications. RESULTS: Out of 12 patients two went into failure, while rest of the patients showed successful outcome. All patients underwent successful surgery. Initially, a silicon conformer was placed, which was later on replaced with artificial prosthetic eye. CONCLUSION: Regardless of the small sample size, this procedure proved to be a safe and effective method for augmenting orbital volume in anophthalmic sockets in children and adults.

RESUMO

PURPOSE: To describe our experience with retroauricular myoperiosteal autograft for surgical coverage of exposed orbital implants. METHODS: This was a single-center, retrospective, observational cohort study, in which demographic and clinical data were compiled by reviewing the clinical records of anophthalmic patients with implant exposure treated with an autogenous retroauricular myoperiosteal graft at the Instituto de Microcirugía Ocular (IMO, Barcelona, Spain) over the period January 2007 to December 2017. Main outcome was the long-term coverage of implant after retroauricular myoperiosteal autograft; secondary outcome was the rate of post-surgical complications and management. RESULTS: Over the 11-year period, 27 eyes of 27 patients with implant exposure received a retroauricular myoperiosteal autograft. Mean participant age was 47.3 ± 17.9 years (range 9-78, median 45). Primary surgery was enucleation in 8 eyes (29.6%) and evisceration in 19 (70.4%). Implant materials were porous polyethylene in 17 (63%), hydroxyapatite in 3 (11.1%), and bioceramics in 4 (14.8%). In the remaining three patients (11.1%), the implant material and size were unknown. Implant exposure was diagnosed after a mean of 98 ± 111.7 months. Mean exposure diameter was 5.9 ± 3.1 mm. Mean follow-up duration after graft surgery was 37.5 ± 39 months. In four patients (14.8%), implant re-exposure was recorded and in two of these patients a re-graft using the same technique was performed. In the last follow-up session, all patients showed good implant coverage. CONCLUSIONS: Myoperiosteal graft could be a valid option for the long-term management of implant exposure irrespective of primary surgery, exposed area, and implant material.

RESUMO

Purpose: To evaluate the effect of intra-lesional injection of Trichloroacetic acid (TCA) 10% in patients with conjunctival inclusion cysts.Methods: This prospective case series study included all patients with conjunctival inclusion cyst who were referred to our referral center from August 2016 to August 2018. All patients received TCA 10% injection into the conjunctival cyst, and outcomes of the intervention were evaluated at least 6 months later.Results: Ten patients with mean age of 24 ± 17.6 (range 6-65) years including three children received TCA 10% injection into the conjunctival cyst. We included 6 anophthalmic and 4 ophthalmic cases. All patients were treated successfully and no recurrence of the lesion was observed in any case. Mean follow up duration was 18.1 ± 8.3 (range 6-28) months.Conclusion: Intra-lesional injection of TCA 10% is a safe, simple, and effective treatment in patients with conjunctival inclusion cysts including ophthalmic cases and anophthalmic cases, both in adults and in children. This concentration may avoid ocular surface complications.

RESUMO

PURPOSE: To investigate mucoid discharge and the inflammatory response of anophthalmic sockets to cryolite glass prosthetic eye wear. PATIENTS AND METHODS: A total of 101 cryolite glass prosthetic eye wearers used visual analog scales (0-10) to measure frequency, color, volume, and viscosity of mucoid discharge associated with their prosthesis. Standardized photographs of the conjunctiva of their anophthalmic sockets were taken and conjunctival inflammation was semi-quantitatively graded (0-4). All characteristics of discharge and conjunctival inflammation were correlated to eye loss cause, hand washing behavior, and cleaning regimes as explanatory variables. RESULTS: Mean mucoid discharge characteristics (0-10 scale) were frequency 5.3 ± 2.8, color 4.8 ± 3.2, volume 4.9 ± 3.0, and viscosity 5.1 ± 3.2. The mean conjunctival inflammation score (0-4 scale) was 2.1 ± 1.0. There was a positive correlation between the grade of conjunctival inflammation and the frequency (p = 0.018), color (p = 0.001), volume (p = 0.003), and the viscosity of mucoid discharge (p = 0.005). More conjunctival inflammation was associated with higher frequency of cleaning (p < 0.001) and lower frequency of hand washing before removal (p = 0.001). Higher frequency, color, volume, and viscosity of discharge were associated with higher frequency of cleaning (p ≤ 0.001). CONCLUSIONS: Discharge severity associated with prosthetic eye wear was positively correlated with more conjunctival inflammation, higher cleaning frequency, and less hand washing before handling. The results suggest that cryolite glass eyes should not be removed daily for cleaning and that further research should be undertaken to develop a standardized treatment protocol for managing inflammation and mucoid discharge. This protocol would advise hand washing before handling cryolite glass eyes and recommend a minimum period of wear between cleaning sessions.

RESUMO

Purpose: We present a series of primary orbital implant replacement for cases of implant exposure to describe our experience of this one-staged surgical approach. Methods: This study reports on a one-stage technique which involved the removal of the exposed implant or dermis fat graft (DFG) and insertion of a secondary (replacement) in the same procedure, with a variety of materials, including autologous tissue. Re-exposure in a socket where a DFG was placed was defined as a new defect in the newly epithelialized conjunctiva or dehiscence of the dermis-conjunctiva junction. All cases of primary replacement for the management of exposed orbital implant, porous and non-porous, were included, even when there were clinical signs suggestive of infection. The primary outcome was the rate of re-exposure, requiring additional surgical procedures. Infection following primary replacement was a secondary outcome. Results: Seventy-eight patients had primary replacement for the management of an exposed orbital implant. 6.4% had re-exposure at a mean follow-up of 49.7 months (9.1% for ball implants and 4.5% for DFG). The rate of exposure was higher in those with prior signs of infection than those without (8% vs. 3.6%). Re-exposure occurred in 4.5% of cases with DFG implantation, 4.3% of cases with non-porous implants and in 20% of cases with porous implants. Conclusion: Primary replacement for management of exposed orbital implant, porous and non-porous, has a high rate of successful outcome even in cases with presumed or confirmed infection.

RESUMO

Purpose: To describe a novel technique of using a hard palate-dermis fat composite graft (HPDFG) for reconstruction of a contracted anophthalmic socket. Methods: Retrospective, noncomparative, interventional case series of four patients who underwent HPDFG placement by one surgeon between 2010 and 2017. Results: Six harvested HPDFGs were placed in four patients with contracted anophthalmic sockets. A harvested hard palate graft (HPG) and a dermis fat graft (DFG) were adjoined with sutures to form a composite graft. All adhesions and symblephara between the eyelid and the anterior surface of the anophthalmic socket were lysed. The HPG component was attached to the tarsal margin to vertically lengthen the eyelid. The free edge of the DFG was sutured to the cut edge of the bulbar conjunctiva to simultaneously expand the anterior conjunctival surface area and fornix volume. The line of union between the two grafts formed the apex of the new fornix. Four HPDFG were used to reconstruct both the upper and lower lid fornices in two severely contracted sockets. Three patients received post-operative 5-fluorouracil (5-FU) injections. Three patients underwent additional revisions with buccal mucous membrane graft, amniotic membrane graft, full-thickness skin graft, pedicle flap, and dermal fillers. All four patients achieved excellent cosmesis and comfortable prosthesis fit. Conclusions: Composite HPDFG is an effective method of reconstructing a contracted anophthalmic socket by restoring volume, lengthening the posterior lamella, and expanding the fornix to allow for successful prosthesis retention. Adjunctive use of 5-FU injections can delay post-operative cicatrization.

RESUMO

The purpose of this article is to evaluate the three different surface coating on cohesive silicone gel implants in eviscerated rabbit eye sockets. Forty-five albino rabbits underwent right eye evisceration and received hemisphere-shaped cohesive silicone gel implants with smooth (Group 1), textured (Group 2), or polyurethane-coated surface (Group 3) in the socket. The animals were euthanized at 7, 30, and 90 days postoperatively. Computed tomography of the orbits was performed prior to euthanasia. Subsequently, the orbital contents were removed and underwent histologic and morphometric examination. Data were statistically analyzed. There were no adverse effects throughout the study. The majority of implants in the Group 1 exhibited 180° rotation. The Group 3 experienced an intense inflammatory reaction around the implant and implant deformation probably due to pseudocapsule contraction. Cohesive silicone gel implants had good integration into the scleral socket. Optimal results were obtained with cohesive silicone gel textured implants (Group 2). Smooth implants (Group 1) rotated significantly, whereas polyurethane (Group 3) coated implants precipitated an intense inflammatory reaction and were deformed postoperatively.

RESUMO

To compare post-operative results and complications in patients who undergo enucleation with or without suture closure of the conjunctiva. This was a retrospective chart review study. Review of 50 cases of enucleation surgery at the University of Arkansas for Medical Sciences and Arkansas Children's Hospital between July 2011 and December 2014. Criteria for inclusion in the study were all cases of enucleation that had extraocular muscles attached to a spherical orbital implant with or without conjunctival closure, and at least 2 months of postoperative follow up. Post-operative complications were evaluated. A total of 36 cases fulfilled the criteria for inclusion in the study; 12 cases with direct sutured layered direct closure of Tenon's and then conjunctiva and 24 cases with Tenon's capsule sutured closure but without direct conjunctival sutured closure. No implant complications were identified in either group (p = 1.0). Mean follow-up for all groups was 16.71 months (range 2 to 43 mo., SD 11.94). Mean follow up for the non-closure group was 14.42 months (range 2.25 to 36 mo., SD 10.35). Two cases in the conjunctival closure group developed a conjunctival cyst, affecting prosthesis fit, approximately 3 months postoperatively: no such cysts were identified in the non-conjunctival closure group. Fisher exact test for cyst formation between the two groups was not statistically significant (p = 0.1048). Direct conjunctival closure following enucleation surgery does not appear to increase the risk of extrusion, exposure, or infection. Foregoing direct closure decreases surgical time and reduces cost. It is unclear if this decreases conjunctival cyst formation.

RESUMO

PURPOSE: To assess the efficacy and safety of porous and nonporous implants for management of the anophthalmic socket. METHODS: Case series meta-analysis was conducted with no language restriction, including studies from: PUBMED, EMBASE and LILACS. Study eligibility criteria were case series design with more than 20 cases reported, use of porous and/or nonporous orbital implants, anophthalmic socket and, treatment success defined as no implant exposure or extrusion. Complications rates from each included study were quantified. Proportional meta-analysis was performed on both outcomes with a random-effects model and the 95% confidential intervals were calculated. RESULTS: A total of 35 case series studies with a total of 3,805 patients were included in the meta-analysis. There are no studies comparing porous and nonporous implants in the anophthalmic socket treatment. There was no statistically significant difference between porous polyethylene (PP) and hydroxyapatite (HA) on implant exposure: 0.026 (0.012-0.045) vs 0.054 (0.041-0.070), respectively and, neither on implant extrusion: 0.0042 (0.0008-0.010) vs. 0.018 (0.004-0.042), respectively. However, there was a significant difference supporting the use of PP when compared to bioceramic implant: 0.026 (0.012 -0.045) vs. 0.12 (0.06-0.20), respectively, on implant exposure. CONCLUSION: PP implants showed lower chance of exposure than bioceramic implant for anophthalmic socket reconstruction, although we cannot rule out the possibility of heterogeneity bias due to the nature and level of evidence of the included studies. Clinical trials are necessary to expand the knowledge of porous and nonporous orbital implants in the anophthalmic socket management.

RESUMO

One of the most common tumors of the eye diagnosed in childhood is retinoblastoma, which mandates enucleation with adjunctive chemotherapy and radiotherapy to save the patient's life. The most common late enucleation complication is post-enucleation socket syndrome (PESS), which poses a management dilemma for the prosthodontist and surgeon, along with being a major esthetic concern for the patient. The reconstruction of such sockets is complex. The purpose of this clinical report is to describe the rehabilitation of such a pediatric patient with severe PESS. The patient was successfully rehabilitated by presurgical conformer therapy, socket reconstruction surgery with non-meshed intermediate split thickness skin graft (STSG)/Blair-Brown graft, and postsurgical conformer stent. This was followed by fabrication of a custom ocular prosthesis, to achieve favorable functional, physical, and psychological effects.
