RESUMO

PURPOSE: The coronavirus disease 2019 (COVID-19) pandemic led to overall interrupted medical care, resulting in disease progression and morbidity. The study aimed to evaluate clinicopathological presentations and severity of eyelid malignancy during the COVID era, comparing the results with patients presented during pre-COVID era and evaluating the reasons for delayed presentation in patients with advanced eyelid malignancy in the COVID-era. METHODS: This was a comparative, ambispective observational study. Data regarding demographic, clinical, histopathology, and treatment modalities of confirmed cases of eyelid malignancy admitted during the period from March 2020 to September 2022 (defined as COVID era group) were collected and compared with retrospectively collected data from March 2017 to March 2020 (defined as pre-COVID era group). COVID era patients were further categorized as localized and advanced disease. Patients with advanced eyelid malignancy during COVID era were further subjected to a questionnaire to evaluate the reasons for delayed presentation. RESULTS: In total, 115 patients of eyelid malignancy were studied [COVID era group 40 (35%) and pre-COVID era group 75 (65%)]. A statistically significant increase in the duration of disease (P = 0.0001) and advanced tumor T-stage (P = 0.03) was noticed in the COVID era group. Demographic, histopathology, and ocular morbidity details were similar in both groups. The common reasons that led to delay in presentation and treatment in advanced T-stage patients during the COVID era were fear of acquiring COVID, lockdown, and lack of medical facilities. CONCLUSION: During the COVID-19 pandemic, both hospital- and patient-related factors contributed to delay in presentation, leading to advanced-stage disease indicating need of triaging of eyelid malignancy in the event of such pandemics in future.

RESUMO

This was a prospective, interventional, comparative study conducted on patients with congenital simple severe ptosis. A novel method of silicone rod fixation to the tarsus (tarsal tunnel technique, group 1) was done compared with a conventional technique of silicone rod fixation (suture fixation technique, group 2) in frontalis suspension surgery. A total of 30 patients were randomized into two groups of 15 patients each. Postoperatively, MRD1, vertical palpebral aperture, and eyelid fold height were comparable in both groups till the last follow-up with stability in eyelid position. Patient satisfaction scores showed similar results with good-fair satisfaction grading in 13 patients in group 1 and 11 patients in group 2 at 6 months follow-up. No significant complications occurred in either group. Tarsal tunnel fixation of silicone rods is a novel method in sling surgery with optimal cosmetic and function outcomes. Further long-term studies are needed to validate the results of the technique.

RESUMO

INTRODUCTION: Many countries from South-East Asia reported an epidemic of sino-orbital mucormycosis (SOM), otherwise a rare disease, during the coronavirus disease 2019 pandemic. SOM, a potentially fatal disease, is typically treated with orbital exenteration and systemic antifungals after metabolic stabilization. There is no clear evidence of survival benefit of exenteration in the literature, and thus, there have been attempts at globe conserving treatments like orbital infusion after limited debridement and intraorbital injections with Amphotericin B (IOAB). METHODS: We conducted a prospective comparative interventional study at a tertiary eye care hospital to evaluate treatment outcomes with the use of adjunctive IOAB in cases of SOM with mild to moderate orbital disease. RESULTS: Thirty-six patients of SOM with mild to moderate orbital disease were recruited in the study. In the intervention group, 23/26 (885%) eyes had stable orbital disease at the end of treatment (4-6 weeks). No deterioration in visual acuity was noted as a result of treatment. In 8/26 (30.77%) patients, inflammation was noted as a side effect of IOAB requiring temporary discontinuation of injections. The mean follow-up for cases was 14.2 months (range 12-15 months). 1/23 (4.35%) patients had relapse of orbital disease at 3 months. Twenty-one patients are alive on last follow-up. Of the patients who refused treatment (controls), 2/9 (22.22%) patients relapsed. One of these patients with relapse underwent exenteration, while the other was managed with IOAB. At a follow-up of 14 months (range 12-15 months), eight patients are alive. On evaluating the ocular parameters in salvaged eyes, improvement in extraocular movements was noted in 75-80% cases. The degree of proptosis and resistance to retropulsion did not change significantly. CONCLUSION: In the current study, an improvement in the globe salvage rates was noted in cases of SOM with mild to moderate orbital disease treated with adjunctive IOAB as compared to controls at a mean follow-up of 14 months, although it did not achieve statistical significance. The study supports the inclusion of IOAB in routine management of mild to moderate orbital disease.

RESUMO

Background: The aim of the study was to evaluate the outcomes of voriconazole in terms of functional recovery and response on imaging in the management of invasive aspergillosis of orbit. Methods: This was a prospective non-comparative interventional study. Diagnosed cases of invasive orbital aspergillosis were studied in a tertiary care hospital. Intravenous voriconazole followed by oral treatment was given. Sinus debridement was done, where needed. The response to treatment was assessed clinically and on radiology. Results: A total of 10 diagnosed cases of invasive orbital aspergillosis were studied. Nine cases (90%) occurred in immunocompetent patients. Predisposing sinus infection was seen in 8 patients (80%). The most common presenting complaint was the protrusion of eye. On voriconazole treatment, there was a statistically significant improvement in vision and extraocular movements from first week onwards (p = 0.01 and p = 0.02, respectively) and reduction in proptosis from second week onwards (p = 0.003). Imaging was done at three months follow-up which revealed a good response to treatment in 90% of patients. All patients tolerated the drug well except one who had transient hepatic dysfunction. The mean follow-up was 5.8 months (range: 3-12 months). There was no recurrence of disease till the last follow-up. Conclusion: Invasive orbital aspergillosis commonly presents as sino-orbital disease, mostly in immunocompetent adult patients. Voriconazole is a safe and effective drug with good short-term clinical outcome.

RESUMO

Nasal natural killer/T-cell lymphoma (NK/TCL) is a rare form of malignant non-Hodgkin lymphoma (NHL) with a far more rare involvement of orbit. The orbital involvement has a highly variable clinical presentation. Here, we report one such case of a 40-year-old male patient who presented with swelling in the right upper and lower eyelids with the diminution of vision for 12 days. He had a history of blocked nose for two months. Clinical examination and CT scan of the orbit and paranasal sinuses suggested a diagnosis of right orbital cellulitis with pansinusitis. A combination of intravenous antibiotics was started, and functional endoscopic sinus surgery was done. Histopathology was a suggestive of nasal NK/TCLl NHL. After proper staging, the patient was given chemotherapy and radiotherapy. There was a complete resolution of mass with no recurrence over a follow-up of 10 months.

RESUMO

Introduction: Eyelid sebaceous gland carcinoma (SGC) is an aggressive malignancy. Surgical excision is the standard treatment for non-metastatic eyelid SGC. This study aimed to evaluate treatment outcomes with use of neoadjuvant chemotherapy (NACT) and any change in ease/difficulty of surgical treatment in such cases. Methods: This was a prospective interventional study conducted over 24-month period. Histopathologically, confirmed cases without any systemic metastasis were included. Clinico-demographic details were collected for 30 patients. 10 patients received NACT using cisplatin and 5-FU. Tumour response was evaluated using RECIST criteria. An ease of surgery questionnaire was used to assess difficulty of surgical treatment before and after NACT. Results: Of the 30 patients evaluated for recruitment, 37% had recurrent SGC and 72% had advanced tumour stage. Ten patients were recruited for NACT. There was partial response in 80% and complete response in 10% cases. Tumour T category downstaging was seen in 50% of cases. While tumour dimensions/volume reduced substantially, surgical ease improved in only 40% cases. Conclusion: A significant proportion of SGC patients evaluated in our study presented with recurrent and/or advanced disease. NACT caused tumour regression in 90% of cases. However, surgical ease improvement was limited, pointing to a need for surgical modification in such cases. Corneal ulceration was noted in 2 cases with large tumours causing a complete mechanical ptosis. Overall, the study introduced an ease of surgery questionnaire and provided insights into benefits and challenges of using NACT for eyelid SGC management.

RESUMO

PURPOSE: To study the outcomes of minor salivary gland transplantation for severe dry eye disease secondary to chronic Steven Johnson Syndrome. METHODS: It was an ambispective, interventional case series conducted at Rajendra Prasad Centre for Ophthalmic Sciences, Delhi, India from 2022 to 2023 evaluating the outcomes of minor salivary gland transplantation with anchorage of the minor salivary glands to superior rectus muscle in twenty cases of severe dry eye disease secondary to chronic Steven-Johnson Syndrome. The pre-operative clinical parameters were compared to those at post-operative 1 year follow-up. RESULTS: At 1 year follow-up, there was an improvement in mean Schirmer-1 value (p = 0.0004), hyperemia score (p = 0.0004), keratinization score (p = 0.04), corneal epithelial defect score (p = 0.0004), corneal opacification score (p = 0.001), corneal neovascularization score (p = 0.001), palisades of Vogt score (p = 0.007), corneal keratinization score (p = 0.04) and corneal conjunctivalization score (p = 0.08). CONCLUSION: The minor salivary gland transplantation is a viable management option for cases with severe dry eye disease secondary to chronic Steven Johnson Syndrome with clinical improvement in corneal and conjunctival parameters of the ocular surface.

RESUMO

PURPOSE: This study aimed to determine the clinical indications for orbital exenteration, demographic profile of these patients, and clinicopathologic correlations in the current times and to compare these results with previous published data. METHODS: It was a retrospective study. All exenterations performed at a tertiary eye care center over a period of 20 years (from January 2001 to June 2020) were retrospectively evaluated. Patient records were reviewed to obtain demographic data, presenting symptoms and their duration, laterality, and clinical and histopathologic diagnosis. RESULTS: A total of 352 cases (males:females = 222:130) who underwent exenteration were identified. Patients age ranged from 11 months to 87 years (mean: 43.86 years, median: 50 years). The most common indication for exenteration was found to be eyelid malignancy in 54.36%, followed by retinoblastoma in 18.75% and primary orbital tumors in 14.49%. Out of 156 cases of eyelid malignancies requiring exenteration, squamous cell carcinoma (SCC) was the most common histologic subtype ( n = 94, 60.26%), followed by sebaceous gland carcinoma ( n = 40, 25.64%) and basal cell carcinoma ( n = 20, 12.82%). The most common primary orbital tumors requiring exenteration were adenocystic carcinoma of the lacrimal gland in adults and rhabdomyosarcoma in the pediatric age group. Benign conditions requiring exenteration included fulminant fungal orbital infections and lymphangioma among others. CONCLUSION: The number of exenterations performed have significantly increased in terms of absolute numbers. However, the ratio of exenteration to other tumor-related surgeries, mainly excision biopsy, has reduced compared to that reported from a previous study. The most common indication in our study remains eyelid malignancy followed by intraocular malignancy. However, SCC has emerged as the most common tumor histologic subtype requiring exenterations.

RESUMO

Receptor tyrosine kinases (RTKs) serve as molecular targets for the development of novel personalized therapies in many malignancies. In the present study, expression pattern of receptor tyrosine kinases and its clinical significance in orbital RMS has been explored. Eighteen patients with histopathologically confirmed orbital RMS formed part of this study. Comprehensive q-PCR gene expression profiles of 19 RTKs were generated in the cases and controls. The patients were followed up for 59.53 ± 20.93 years. Clustering and statistical analysis tools were applied to identify the significant combination of RTKs associated with orbital rhabdomyosarcoma patients. mRNA overexpression of RTKs which included MET, AXL, EGFR was seen in 60-80% of cases; EGFR3, IGFR2, FGFR1, RET, PDGFR1, VEGFR2, PDGFR2 in 30-60% of cases; and EGFR4, FGFR3,VEGFR3 and ROS,IGFR1, EGFR1, FGFR2, VEGFR1 in 10-30% of cases. Immunoexpression of MET was seen in 89% of cases. A significant association was seen between MET mRNA and its protein expression. In all the cases MET gene expression was associated with worst overall survival (P = 0.03).There was a significant correlation of MET mRNA expression with RET, ROS, AXL, FGFR1, FGFR3, PDGFR1, IGFR1, VEGFR2, and EGFR3 genes. Association between MET gene and collective expression of RTKs was further evaluated by semi-supervised gene cluster analysis and Principal component analysis, which showed well-separated tumor clusters. MET gene overexpression could be a useful biomarker for identifying high risk orbital rhabdomyosarcoma patients. Well-separated tumor clusters confirmed the association between MET gene and collective expression of RTK genes. Therefore, the therapeutic potential of multi-kinase inhibitors targeting MET and the 9 other significant RTKs needs to be explored.

RESUMO

BACKGROUND: Pigmentation could be a relevant prognostic factor in uveal melanoma (UM) development. Microphthalmia-associated transcription factor (MITF) regulates melanin synthesis by activating tyrosinase-related protein 2 (TYRP2) and silver protein (SILV) that induce the melanogenesis pathway. Although their oncogenic potential has been observed in various malignancies but has not been investigated in UM Asian population. Our aim is to study the ultrastructure of melanosomes and the prognostic significance of pigmentation markers such as TYRP2, MITF and SILV in UM. METHODS: Transmission electron microscopy was performed to compare the ultrastructure of melanosomes in the normal choroid and UM cases. Immunoexpression of TYRP2, SILV and MITF was analysed in 82 UM samples. The mRNA expression level of all genes was measured in 70 UM cases. A statistical correlation was performed to determine the prognostic significance of all markers. RESULTS: Premelanosomes and mature melanosomes undergoing dedifferentiation were observed in high-pigmented UM cases as compared with low-pigmented UM cases. Seventy per cent of UM cases showed high SILV expression while TYRP2 and MITF expression was present in 58% and 56% of cases, respectively. At the mRNA level, upregulation of TYRP2, SILV and MITF markers was seen in around 50% of UM cases, which was statistically significant with high pigmentation. Reduced metastatic-free survival was statistically significant with the MITF protein expression. CONCLUSION: Our results demonstrated that ultrastructural changes in melanosomes and high expression of TYRP2, MITF and SILV could dysregulate the melanogenesis pathway and might be responsible for the aggressive behaviour of UM.

RESUMO

Introduction. Invasive mucormycosis (IM) is a potentially fatal infection caused by fungi of the order Mucorales. Histopathology, culture, and radiology are the mainstays of diagnosis, but they are not sufficiently sensitive, resulting in delayed diagnosis and intervention. Recent studies have shown that PCR-based techniques can be a promising way to diagnose IM.Hypothesis/Gap Statement. Early diagnosis of fungal infections using molecular diagnostic techniques can improve patient outcomes, especially in invasive mucormycosis.Aim. The aim of this study was to evaluate the utility of our in-house mould-specific real time PCR assay (qPCR) in comparison with the commercially available real time PCR (MucorGenius PCR), for the early diagnosis of mucormycosis in tissue samples from patients with suspicion of invasive mucormycosis (IM). This in-house assay can detect and distinguish three clinically relevant mould species, e.g. Aspergillus spp., Mucorales and Fusarium spp. in a single reaction with only one pair of primers, without the need for sequencing.Methodology. We enrolled 313 tissue samples from 193 patients with suspected IM in this prospective study. All cases were classified using EORTC/MSGERC guidelines. All samples were tested using traditional methods, in-house qPCR, and MucorGenius PCR.Results. Using direct microscopy as a gold standard, the overall sensitivity and specificity of in-house qPCR for detection of IM was 92.46% and 80% respectively, while that of the MucorGenius PCR was 66.67% and 90% respectively. However, co-infection of IM and IA adversely affected the performance of MucorGenius PCR in detection of IM.The in-house PCR detected Aspergillus spp. in 14 cases and Fusarium spp. in 4 cases which showed clinical and radiological features of fungal sinusitis. The in-house qPCR also performed better in detecting possible cases of IM. This aids early diagnosis and appropriate treatment to improve patient outcomes.Conclusion. Because the in-house PCR is not only sensitive and specific, but also entirely based on SYBR Green for detection of targets, it is less expensive than probe-based assays and can be used on a regular basis for the diagnosis of IM in resource-constrained settings. It can be used to distinguish between mucormycosis and fungal sinusitis caused by Aspergillus and Fusarium in high-risk patients, as well as to accurately detect Mucorales in fungal co-infection cases.

RESUMO

PURPOSE: To excise external angular dermoid cyst (EADC) by transconjunctival approach and compare the surgical outcomes with the standard transcutaneous approach. DESIGN: This was a prospective, pilot, interventional, comparative study. METHODS: Patients with EADC with no or minimal fixity to the underlying bone on palpation and limited to eyelid were recruited. Patients were randomized into 2 groups; group 1 included patients with transcutaneous approach, and group 2 included patients with transconjunctival approach. The parameters assessed were intraoperative complications, duration and ease of surgery, postoperative complications, and overall satisfaction. RESULTS: Six children with a painless, round lesion in outer aspect of eyelid were recruited in each group. None of the patients had any intraoperative or postoperative complications, including dysfunction of eyelid contour and fold, persistence or late occurrence of lateral eyelid droop, excessive or recurrence of swelling, and ocular surface problems, especially in group 2, but a skin scar though hidden was inevitable in group 1. The duration of surgery was comparable with better ease of surgery in group 1 and a gradual learning curve in group 2. The overall satisfaction scores were significantly better in group 2 (p < 0.0001). In group 1, parents of 5 of 6 patients had to be reassured that the skin scar will fade with time. CONCLUSION: Transconjunctival excision of EADC is a viable and novel approach in patients with mobile cyst that is limited to the eyelid with no obvious bony fossa. Main limitations of the approach are that it requires surgical expertize, provides less surgical space, and has a gradual learning curve.

RESUMO

OBJECTIVE: End-stage ocular diseases usually end up with atrophic bulbi or phthisis bulbi leading to orbital volume loss which needs to be addressed. We studied the use of autologous fat for volume augmentation of the orbit because it is minimally invasive and allows early rehabilitation with the use of an artificial eye. DESIGN: It was a prospective, interventional study. METHODS: A total of 14 eyes of 14 patients with atrophic bulbi with shrinkage or phthisis bulbi with no perception of light (PL) and aged older than 18 years were included for the study purpose. Painful or inflamed eyes or suspected intraocular tumors were excluded. An autologous fat graft was obtained from the lower abdomen or buttocks and injected into the retrobulbar space using a 20-gauge cannula after adequate peribulbar anesthesia. Outcomes measures were patient satisfaction, change in Hertel's exophthalmometry, vertical and horizontal palpebral aperture, and socket volume. RESULTS: Hertel exophthalmometry showed a significant improvement both with and without an artificial eye from 14.92 ± 2.3 mm to 16.71 ± 1.94 mm (p-value 0.003 without an artificial eye). The vertical palpebral aperture also showed a significant improvement from 5 ± 1.70 mm to 6.71 ± 1.58 mm (p-value < 0.001). There was a significant reduction in the socket volume from 1.22 ml to 0.39 ml (p-value < 0.001). No local or donor site complications were seen. CONCLUSIONS: Autologous fat transfer is a minimally invasive, safe, and effective procedure for orbital volume augmentation in small, nonseeing eyes. The short-term outcome of our study was good in most patients and can be considered for such patients.

RESUMO

PURPOSE: This study compares the 8th edition staging of AJCC for prognosis of eyelid Sebaceous Gland Carcinoma (SGC) patients with respect to the 7th edition. METHODS: A retrospective study was undertaken over a period of 100 months. Ninety-nine histopathologically proven cases of eyelid SGC available for follow-up were recruited. Patients were staged by both the 7th and 8th editions of AJCC and followed up at six monthly intervals after surgery. RESULTS: Of the 99 eyelid SGC patients recruited, recurrence and orbital invasion developed in 22%, lymph node metastasis in 21% and 4% had distant metastasis and also died. High-risk features include tumour size>20 mm, orbital invasion, exenteration and staging by both the 7th and 8th editions of AJCC. Cox regression analysis revealed that staging by AJCC 8th edition was associated with greater risk for local recurrence (HR 3.01,95% CI-1.65-5.51%, p < 0.01) lymph node metastasis (HR 8.26, 95% CI 3.96-17.19%, p < 0.01) and disease-free survival (HR 4.61, 95% CI 2.81-7.54). The Kaplan-Meir survival curves of eyelid SGC patients by the 8th edition AJCC staging were also significantly associated with lymph node metastasis (p < 0.01), tumour-related deaths (p < 0.01) and reduced disease-free survival (p = 0.07). The higher Harrell's values by the 8th edition signify better predictive value for lymph node metastasis and DFS (disease-free survival). The lower AIC values indicate a better monotonicity of gradients for lymph node metastasis, recurrence and DFS. CONCLUSION: Staging by the 8th AJCC edition is, therefore, recommended for eyelid SGC as it gives a better perspective about disease outcome. The orbital extension was the single most important predictor of lymph node metastasis, recurrence and death.

RESUMO

Existing clinical indicators for metastatic risk classification and patient treatment of uveal melanoma (UM) in the Asian population are limited. Preferentially expressed antigen in melanoma (PRAME) has gained attention in the prognosis of cancers and considered as a potential biomarker in many tumors including UM. Therefore, this study investigated the expression of PRAME and its association with loss of nuclear BAP1 (nBAP1) as well as its correlation with clinicopathological parameters and patient outcome. Immunohistochemical expression of PRAME and BAP1 proteins were assessed in 66 prospective cases of UM. mRNA expression level was measured by quantitative real-time PCR. Kaplan-Meier curves and Cox proportional hazard models were used to analyze the correlation of protein expression with clinicopathological parameters, metastasis-free survival and overall survival. Nuclear PRAME (nPRAME) expression and loss of nBAP1 were observed in 24 and 62% cases, respectively. PRAME mRNA expression level was found to be upregulated in 64% (7/11) of metastatic patients. mRNA and immunoexpression of nPRAME were statistically significant with many clinicopathological high-risk factors. On univariate and multivariate analyses, high mitotic activity, extraocular invasion and presence of nPRAME expression were statistically significant (p < 0.05). On Kaplan-Meier survival analysis, patients expressing PRAME had significantly reduced metastasis-free survival (MFS) and overall survival (OS). MFS and OS were also reduced in patients expressing PRAME along with loss of nBAP1. Our data show that nPRAME expression, in combination with loss of nBAP1, could be a useful predictive biomarker in the therapeutic management of UM patients at high risk.

RESUMO

OBJECTIVES: To study the thickness of levator palpebra superioris-Muller's muscle complex (LMC) on ultrasound biomicroscopy (UBM) and to correlate with the clinical response to botulinum toxin A (BTA) injection in patients with inactive-stage of thyroid-related upper eyelid retraction (UER). We also studied the correlation of clinical parameters, preinjection with postinjection values. METHODS: This was a prospective, interventional study. Patients with thyroid-related UER who underwent subconjunctival injection of BTA were recruited. Demographic data and clinical details were evaluated. UBM (50 MHz) was done to measure the thickness of LMC. Patient's satisfaction was graded at each follow-up. Follow-up was done at 1 week, 1 month, and 3 months' time intervals. RESULTS: A total of 13 patients were recruited and 26 eyes were divided into two groups; group 1 included eyes with UER (n = 17), and group 2 included eyes without UER (n = 9). There was a statistically significant reduction in margin reflex distance 1 (MRD1) after BTA injection at 1-week, 1-month, and 3-months follow-up with maximum reduction at 1 month. The mean LMC thickness of 26 eyes was 0.96 mm which was found to be significantly more than normal controls. On comparison of mean LMC thickness with the amount of UER and reduction in MRD1, we did not find a significant difference. CONCLUSIONS: Patients with TED have significantly thicker LMC on UBM than controls. Further studies are needed with a larger sample size on the correlation of UBM features of levator aponeurosis with response to BTA injection.

RESUMO

CLINICAL RELEVANCE: Patients undergoing exenteration have significant anxiety and depression, and lower quality of life that worsens after surgery. Therefore, counselling by an eye health-care provider along with the team of psychologist and psychiatrist could be provided pre-operatively to assess baseline psychosocial status and be continued post-operatively to look for any deterioration. BACKGROUND: Orbital exenteration comes with psychological trauma of disfigurement of face. The study aimed to evaluate the quality of life, anxiety and depression in patients undergoing orbital exenteration, before and after the procedure; and also compared the same with patients previously rehabilitated by spectacle-mounted prosthesis after exenteration. METHODS: It was a prospective cohort study. Group I included patients who were planned to undergo orbital exenteration, and group II were those already using spectacle-mounted prosthesis post orbital exenteration for at least 3 months. Level of depression was assessed using Patient Health Questionnaire-9(PHQ-9), anxiety using Generalised Anxiety and Depression scale-7(GAD-7), and quality of life was assessed using Functional Assessment of Cancer Therapy- General (FACT-G) score. RESULTS: A total of 19 patients were recruited in group I and 10 patients in group II. The baseline demographic factors were comparable. The scores for PHQ-9 and GAD-7 were significantly higher at 3-month post-exenteration follow-up, indicating significantly higher levels of anxiety and depression after orbital exenteration in group I. Both these scores were significantly lower in group II compared to group I (3 months follow-up), indicating lower levels of anxiety and depression after rehabilitation with prosthesis. The FACT-G and its subscores were all significantly higher in group II patients compared to post-operative scores of group I patients, indicating higher overall quality of life after rehabilitation with prosthesis. CONCLUSIONS: Patients undergoing exenteration have a significant level of anxiety and depression, and lower quality of life that worsens after orbital exenteration.

RESUMO

BACKGROUND: Cicatricial ectropion can be corrected by invasive surgical modalities such as full-thickness skin graft, lateral tarsal strip procedure, etc., which are associated with donor site morbidity and additional scars. Use of autologous fat graft (AFG) in treatment of burn scars has previously shown encouraging clinical results as to skin color, texture, and softness. OBJECTIVE: We aim to introduce the use of AFG for the correction of mild to moderate grades of cicatricial ectropion of the lower eyelid in adult patients. METHODS: This was a prospective, interventional, non-comparative, pilot study including 5 patients with a cicatricial ectropion of grade I-III. All these patients underwent a pre-injection workup to assess anatomical outcomes (grade of ectropion, vertical palpebral aperture (VPA), lagophthalmos, and eyelid retraction), functional outcomes (dry eye status) and aesthetic outcome (change of scar color, thickness, pain, and consistency). RESULTS: At 6-months follow-up assessment, all patients had improvement in grade of ectropion, significant improvement in VPA and eyelid retraction, and almost complete resolution of lagophthalmos in all the three patients who had pre-injection lagophthalmos. There was a significant improvement in scar color, thickness and consistency on Visual Analogue Score (VAS) with no donor site or systemic complications after the procedure but mild pain on day 1 post-injection at the donor site CONCLUSION: AFG transfer of cicatricial ectropion not only eludes the need of a invasive surgery but provides satisfactory correction with stable outcome with an overall improvement in texture of the scar and has low risk.

RESUMO

A quadragenarian male presented with gradual protrusion of the left eyeball for 7-8 months' duration. On examination, the best corrected visual acuity in the right eye was 20/20, while in the left eye there was no light perception. Contrast-enhanced CT scan revealed a well-defined fat-density mass in the extraconal compartment of the left superior orbit, causing inferolateral globe dystopia with resultant stretching of the optic nerve. Provisionally, orbital dermoid or lipoma was considered in the differential diagnosis. Anterior orbitotomy with complete excision of the mass was performed under general anaesthesia. Histopathological examination revealed an encapsulated, lobulated lesion consisting of mature lipocytes and occasional blood vessels with thrombi. The lesion was divided into numerous lobules by thick fibrous bands. Immunohistochemical stain S100 was strongly positive in the lipocytes. At 3 months of follow-up, the patient had moderate ptosis with leucomatous corneal opacity with no recurrence.
