Surgical management of orbital implant exposures after evisceration or enucleation: Retrospective study - Limoges University Hospital.

INTRODUCTION: Implant exposure is the most frequent complication after evisceration or enucleation, and multiple surgical techniques for the management of orbital implant exposure. The goal of our study is to investigate the success rate and risk factors for failure of various surgical procedures. METHODS: This was a retrospective study performed at the University Hospital of Limoges. We collected data from the files of every patient operated on for implant exposure between January 2005 and December 2020. The main criterion was the percentage of success for each procedure. Secondary objectives were to identify risk factors for failure of Müller's muscle flaps and to determine the incidence of post-enucleation socket syndrome depending on whether the orbital implant was maintained. RESULTS: Fifty-one patients were included: 26 patients who underwent Müller's muscle flap, 16 dermis-fat graft, 3 conjunctival flap, 2 amniotic membrane graft, 1 temporalis fascia graft, 1 buccal mucosa graft, 1 implant rotation, and 1 implant exchange. The dermis-fat grafts were more successful (87.5%) than the Müller's muscle flaps (52.2%) (P=0.0213). The study highlighted the importance of good vascularization of the implant (OR=32.00, P-value=0.0245) for the success of Müller's muscle flaps, and we found no statistically significant difference between the patients who maintained their implants and those who did not (P=0.3865) with regard to the incidence of post-enucleation socket syndrome. CONCLUSION: Müller's muscle flap may remain a reasonable option in the management of medium-sized implant exposures of well-vascularized implants confirmed on MRI in patients with no systemic healing disorders. Dermis-fat graft remains the option of choice in other cases, especially in large exposures or complicated orbits.

Streptococcus pneumoniae endophthalmitis: clinical settings, antibiotic susceptibility, and visual outcomes.

Streptococcus pneumoniae endophthalmitis is clinically more severe, more difficult to treat, and carry a higher risk of vision loss, evisceration, or enucleation. This study is to investigate the clinical settings, antibiotic susceptibility, and visual outcomes of S. pneumoniae endophthalmitis at a tertiary referral center in Taiwan. S. pneumoniae endophthalmitis was diagnosed in 38 eyes of 38 patients. The main clinical features were postcataract endophthalmitis (n = 13, 34%) and endophthalmitis associated with corneal ulcer (n = 12, 32%), trauma (n = 6, 16%), endogenous etiology (n = 4, 11%), trabeculectomy (n = 2, 5%), and pterygium excision-related scleral ulcer (n = 1, 3%). Presenting visual acuity ranged from counting fingers to no light perception. Pars plana vitrectomy with intravitreal antibiotics was performed in 17 eyes (39%) in primary or secondary treatments. S. pneumoniae isolates were susceptible to vancomycin (38/38, 100%), penicillin (37/38, 97%), ceftriaxone (37/38, 97%), cefuroxime (12/15, 80%), levofloxacin (13/15 ,87%), and moxifloxacin (15/17, 88%). Final visual acuity was better than 20/400 in 3 of 38 eyes (8%), 5/200 to hand motions in 3 eyes (8%), and light perception to no light perception in 32 eyes (84%). Ten eyes (26%) underwent evisceration or enucleation. Although S. pneumoniae isolates were susceptible to vancomycin, S. pneumoniae endophthalmitis had a very poor visual prognosis.

Ruthenium-106 versus iodine-125 plaque brachytherapy of 571 choroidal melanomas with a thickness of ≥5.5 mm.

BACKGROUND: Episcleral brachytherapy is the most common eye-preserving treatment for medium-sized choroidal melanomas. γ-emitting iodine-125 (125I) and ß-emitting ruthenium-106 (106Ru) are widely used. The latter is however generally reserved for thinner tumours (<6 mm). In this study, we compare ocular and patient survival in thicker tumours treated with the respective radioisotope. METHODS: All patients with ≥5.5 mm thick choroidal melanomas who were treated with plaque brachytherapy at a single institution between 1 November 1979 and 31 December 2015 were included (n=571). Size-controlled Cox regression HRs for postbrachytherapy enucleation, repeated brachytherapy and melanoma-related mortality were calculated, as well as Kaplan-Meier disease-specific survival and relative 10-year survival in matched subgroups. RESULTS: 317 patients were treated with 106Ru and 254 with 125I. The rate of repeated brachytherapy was significantly higher among patients treated with 106Ru (8%) than with 125I (1%, p<0.001). Size-controlled Cox regression HRs for postbrachytherapy enucleation (125I vs 106Ru 0.7, p=0.083) and melanoma-related mortality were not significant (125I vs 106Ru 1.1, p=0.63). Similarly, Kaplan-Meier disease-specific and relative 10-year survival was comparable in matched groups of 5.5-7.4 mm (relative survival 106Ru 59%, 125I 56%) and ≥7.5 mm thick tumours (relative survival 106Ru 46%, 125I 44%). CONCLUSIONS: Rates of repeated brachytherapy were significantly higher among patients treated with 106Ru versus 125I for thick choroidal melanomas. There were, however, no significant differences in rates of enucleation or patient survival.

Comparing the Management of Eye Injuries by Coalition Military Surgeons during the Iraq and Afghanistan Conflicts.

PURPOSE: To compare incidences, ocular injury types, and treatment performed on United States and United Kingdom military service members and host nation civilians within the Iraq and Afghanistan conflicts to inform future military surgical training requirements and military medical planning. The United States routinely deployed ophthalmologists, whereas the United Kingdom did not. DESIGN: Retrospective cohort study of the United States and United Kingdom military Joint Theatre Trauma Registries. PARTICIPANTS: All patients with eye injuries treated at a deployed Military Treatment Facility between March 2003 and October 2011. METHODS: An adjusted multiple logistic regression model was performed using enucleation or evisceration and primary open-globe repair as dependent variables and casualty nationality, location, and the presence of an ophthalmic surgeon as independent variables. MAIN OUTCOME MEASURES: Incidence of eye removal (enucleation or evisceration) or primary repair for open globe injury. RESULTS: Five thousand seven hundred nineteen of 67 586 (8%) survivors or those who died of wounds were recorded to have sustained eye injuries. The most common eye injuries were open-globe injury without intraocular foreign body (3201/5719 [56%]). Adnexal injuries (eyelid lacerations and damage to lacrimal apparatus) were recorded in 1265 of 5719 patients (22%). The odds of undergoing evisceration or enucleation for open-globe injury was highest in host nation civilians (odds ratio [OR], 9.23; P < 0.001), but there was no evidence of a difference between United States and United Kingdom military service member casualties (P = 0.38). The presence of an ophthalmic surgeon (OR, 16.3; P < 0.001) significantly affected the odds of eye removal. CONCLUSIONS: Eye injuries were more likely to have been treated definitively in United States Medical Treatment Facilities (MTFs), reflecting the absence of ophthalmologists in most deployed United Kingdom MTFs. The Iraq and Afghan conflicts were notable for coalition air dominance; the shape of future conflicts may mandate delays in evacuation, which may affect visual outcomes negatively, particularly if primary repair of patients with open-globe injuries is delayed. This study provides evidence to support the maintenance of specialist ophthalmic surgical competencies in deployed coalition MTFs for future conflicts.

Outcomes of ocular evisceration and enucleation in the British Armed Forces from Iraq and Afghanistan.

BACKGROUND/OBJECTIVES: To evaluate outcomes from all British military patients who underwent eye removal during the Iraq and Afghanistan wars. SUBJECTS/METHODS: Retrospective case note review of all patients (n = 19) who had undergone either evisceration or enucleation, on a database of all military patients repatriated to the Royal Centre for Defence Medicine, Birmingham. RESULTS: Twenty eye removals were performed on 19 patients, of which 14 (70%) were eviscerations and 6 (30%) were enucleations. Orbital wall fractures were seen in 12 (61%) patients, with orbital floor fractures being the most common. The eye removal was a primary procedure in five of fourteen eviscerations, and five of six enucleations. Complications were seen after four (28.6%) eviscerations patients and two (33.3%) enucleations. Postoperative pain was problematic after three (21.4%) eviscerations but no enucleations. Orbital implants were placed during three of the five primary enucleations, with good outcomes in two. One patient however required implant retrieval and wound washout due to a high risk of infection and communication with the intra-cranial space. CONCLUSIONS: Evisceration and enucleation are both viable options in the management of severe ocular trauma in military patients. Evisceration and enucleation have similar complication rates and outcomes, and both have low rates of sympathetic ophthalmia. Primary orbital implants can be at high risk in cases with orbital roof fracture, but can provide good outcomes in select patients.

Racial, Ethnic, and Socioeconomic Disparities in Retinoblastoma Enucleation: A Population-Based Study, SEER 18 2000-2014.

PURPOSE: To determine the effect of race, ethnicity, and census tract-level composite socioeconomic status (SES) on retinoblastoma enucleation. This study augments Truong and associates, providing multivariate analyses combining sociodemographic and clinical characteristics with more accurate SES measures. We hypothesized that children from nonwhite, Hispanic, and lower socioeconomic backgrounds would have increased adjusted odds of enucleation. DESIGN: Retrospective cohort analysis. SETTING: Multicenter population-based study using the Surveillance, Epidemiology, and End Results (SEER) 18 Registries. STUDY POPULATION: Children aged 18 years and younger diagnosed with retinoblastoma between 2000 and 2014. Subjects were identified using International Classification of Diseases-Oncology (ICD-O) site and morphology codes. MAIN OUTCOME MEASURES: Enucleation odds ratios (ORs) and 95% confidence intervals (CIs). RESULTS: Analysis of 959 retinoblastoma patients revealed that 70.8% were enucleated. Adjusted analyses showed associations between enucleation and Asian (OR 2.00, CI 1.08-3.71) or black (2.42, 1.41-4.16) race, Hispanic ethnicity (1.69, 1.16-2.46), and low SES (1.68, 1.09-2.58). Significantly increased enucleation risk was associated with older age at diagnosis (age 1-2 years 2.55, 1.80-3.61; >2 years 4.88, 2.57-9.25), unilateral disease (5.00, 3.45-7.14), and advanced stage (regional 4.71, 2.51-8.84; distant 3.15, 1.63-6.08). No interactions were observed between race, ethnicity, SES, and stage at diagnosis. Enucleation rates decreased over time across all racial, ethnic, and socioeconomic groups. CONCLUSIONS: Children from nonwhite, Hispanic, and lower socioeconomic backgrounds are more likely to receive enucleation. These associations are independent of stage of diagnosis, suggesting larger systemic disparities in retinoblastoma care. The origin of these differences requires further study and attention by clinicians and policy makers.

Enucleations and Eviscerations for Combat Ocular Trauma Performed During Operations Iraqi and Enduring Freedom: 2001 to 2011.

PURPOSE: To describe the demographics and clinical outcomes of patients who underwent posttraumatic enucleation or evisceration during Operations Iraqi Freedom (OIF) and Enduring Freedom (OEF) from 2001 to 2011. METHODS: The Walter Reed Ocular Trauma Database is a retrospective case series of US Servicemembers and Department of Defense civilians who had combat ocular injuries in OIF and OEF. Data regarding posttraumatic enucleations and eviscerations performed during OIF and OEF were extracted. The main outcomes analyzed were the number of enucleations and eviscerations performed, location of the surgery, laterality, and graft type. The secondary outcome measures included: mechanism of injury and Ocular Trauma Score classification. RESULTS: One hundred nine enucleations and eviscerations were performed on the 890 eyes (12.24%). Sixty-three (57.80%) primary enucleations, 36 (33.03%) secondary enucleations, 5 (4.59%) postretinal detachment repair enucleations, and 5 (4.59%) primary eviscerations were completed. The surgeries were completed at a combat support hospital (57; 52.3%), or Walter Reed Army Medical Center (49; 45.0%). All surgeries were unilateral except in 2 patients. The most common graft type used was silicone (n = 56; 51.38%). Improvised explosive devices caused 76 (69.72%) eye injuries. Ocular Trauma Score were recorded as 56 (51.38%) between 0 and 44, 44 (40.37%) between 45 and 65, and unknown in 9 (8.26%). CONCLUSION: Posttraumatic enucleation or evisceration due to devastating ocular trauma is required in about 15% of ophthalmic patients in modern combat trauma. The psychosocial impact on veterans who have required an enucleation or evisceration from combat trauma has been poorly studied and requires further review.

INADVERTENT INTRAOCULAR SURGERY IN CHILDREN WITH UNSUSPECTED RETINOBLASTOMA: A Study of 14 Cases.

PURPOSE: To study the clinical presentation and treatment outcome of patients who underwent inadvertent intraocular surgery before the diagnosis of retinoblastoma. DESIGN: Retrospective study of 14 patients who had undergone an inadvertent intraocular surgery before the diagnosis of retinoblastoma. RESULTS: The mean age at presentation to the ocular oncology clinic was 69 months. The most common initial misdiagnosis was endophthalmitis (n = 4). The most common inadvertent intraocular surgeries were pars plana vitrectomy (n = 6) with/without lensectomy and evisceration with/without previous pars plana vitrectomy (n = 5). The mean interval between intraocular procedure and initiation of treatment for retinoblastoma was 7 months. At presentation in the oncology clinic, the tumor was intraocular (n = 3), with extrascleral tumor extension (n = 11), and/or optic nerve tumor extension (n = 5). All patients were started on multimodal treatment including 12 cycles of high-dose systemic chemotherapy, enucleation or orbital exenteration, and orbital external beam radiotherapy. Over a mean follow-up period of 27 months, 8 (57%) patients died because of progressive disease despite initiation of treatment. CONCLUSION: Misdiagnosis and inadvertent surgical intervention in cases of retinoblastoma in combination with delayed initiation of appropriate treatment is associated with poor prognosis. High index of suspicion for retinoblastoma is needed to avoid misdiagnosis and mismanagement.

Enucleation in Asian Indian patients: a histopathological review of 2009 cases.

OBJECTIVE: To review the indications of enucleation in Asian Indian patients and study the trend over the 22-year period. METHODS: Retrospective study of 2009 patients who underwent enucleation. RESULTS: The mean age at presentation of patients who underwent enucleation was 155 months The histopathology diagnosis included a benign tumor (n = 22, 1%), malignant tumor (n = 1472, 73%), acute trauma (n = 93, 5%), retinal vascular disease (n = 50, 3%), inflammatory/infective pathology (n = 33, 2%), or other miscellaneous/non-specific diagnosis (n = 460, 23%). There was a good correlation between the clinical and histopathology diagnoses at 96%. The most common indication for enucleation in young patients ( ≤ 20 years) was retinoblastoma (n = 1257, 82%; p < 0.001), atrophic bulbi or phthisis bulbi (n = 163, 39%; p < 0.001) in middle-age adults, and uveal melanoma (n = 25, 42%; p < 0.001) in older adults. Over the years, there was a decreasing trend of enucleations for atrophic bulbi/phthisis bulbi/painful blind eye (33% from the years 1996 through 2000 to 7% from 2010 to 2018; p < 0.001) and acute trauma (3% from the years 1996 through 2000 to < 1% from 2010 to 2018; p < 0.001) and an increasing trend for intraocular tumors including retinoblastoma (56% from the years 1996 through 2000 to 73% from 2010 to 2018; p = 0.01) and uveal melanoma (3% from the years 1996 through 2000 to 11% from 2010 to 2018; p < 0.006). CONCLUSION: In Asian Indian population, malignant tumors remain the most common indication for enucleation in young and older patients, while desire for better cosmesis with customized ocular prosthesis is the main indication for enucleation in middle-age adults.

The Demography and Etiology of Pediatric Enucleation in a Tertiary Eye Center in North China, 2001-2015.

PURPOSE: To review the demography and etiology of pediatric enucleation over time. METHODS: Pediatric ophthalmic inpatients recruited and recorded (aged 0-14 years) at Shandong Eye Institute from January 2001 to December 2015 were reviewed. Changes during the three periods from 2001 to 2005, 2006 to 2010, and 2011 to 2015 were compared and analyzed. RESULTS: A total of 9307 pediatric inpatients were reviewed. Of these, 71 patients (71 eyes) who had been treated by enucleation were analyzed; 46 were boys (64.79%) and 25 were girls (35.21%). The mean age at enucleation was 9 (0-14) years. The pediatric enucleation rate during this 15-year period was 0.76% (71/9307), with a decreasing trend (p < 0.001). From 2001 to 2005, the figure was 3.45% (43/1245); it dropped to 0.80% (26/3231) from 2006 to 2010 and then dropped further to 0.04% (2/4831) by 2015. Trauma (52.1%, 37/71) was the leading etiology. Overall, 89.2% (33 eyes) exhibited open globe injuries; 78.4% (29/37) of these involved boys. In the cases with open injuries, the mean age at the time of trauma was 6.0 (0-14) years and the mean age at enucleation was 11 (2-14) years. Retinoblastoma (RB) (22.5%, 16/71) was the second-most common etiology; 68.8% (11/16) of these cases involved girls and the mean age at enucleation was 2 (0-5) years. CONCLUSION: A decrease in pediatric enucleation in North China, especially in Shandong Province, was observed over time, possibly because of better surgical techniques, improvements in the treatment of RB, and public health interventions in children.

Retinoblastoma: towards an earlier diagnosis. / Retinoblastoma: hacia un diagnóstico más precoz.

OBJECTIVES: The number of enucleations and visual sequels due to retinoblastoma is high. The aim of this study was to evaluate the different diagnostic aspects and propose strategies that might improve the clinical management of this condition. METHOD: A retrospective study was conducted on 38 patients with retinoblastoma studied genetically (29 unilateral, 9 bilateral). The evaluation included: age of onset, clinical signs, and time since onset, number of enucleations, time to diagnosis, and survival at 5 years. RESULTS: Leukocoria was the main clinical sign (present in 90% of cases). The mean diagnostic delay was 3.2 months. Among the unilateral cases, the eyes were enucleated in 76%, and 55% in the bilateral forms. Only one death was found among the 25 patients followed-up for at least 5 years. CONCLUSIONS: Retinoblastoma diagnostic and treatment strategies need to be updated. Good coordination between paediatricians and ophthalmologists is essential for this. Its management in reference centres, which have the necessary technology and experience, should contribute to increase the rate of organ preservation.

Microbial keratitis-induced endophthalmitis: incidence, symptoms, therapy, visual prognosis and outcomes.

BACKGROUND: To evaluate symptoms, therapies and outcomes in rare microbial keratitis-induced endophthalmitis. METHODS: Retrospective study with 11 patients treated between 2009 and 2014. Clinical findings, corneal diseases, history of steroids and trauma, use of contact lenses, number and type of surgical interventions, determination of causative organisms and visual acuity (VA) were evaluated. RESULTS: The incidence of transformation from microbial keratitis to an endophthalmitis was 0.29% (n = 11/3773). In 90.9% (n = 10/11), there were pre-existent eyelid and corneal problems, in 45.5% (n = 5/11) rubeosis iridis with increased intraocular pressure and corneal decompensation, and in 18.2% (n = 2/11), ocular trauma. Specimens could be obtained in 10 of 11 samples: 33.3% of those 10 specimens were Gram-positive coagulase-negative Staphylococci (n = 3/10) or Gram-negative rods (n = 3/10) and 10.0% Staphylococcus aureus (n = 1/10). In 30% (n = 3/10), no pathogens were identifiable. 72.7% (n = 8/11) of all keratitis-induced endophthalmitis were treated with vitrectomy and 9.1% (n = 1/11) with amniotic-membrane transplantation. In 27.3% (n = 3/11) the infected eye had to be enucleated - 18.2% (n = 2/11) primarily, 9.1% (n = 1/11) secondarily. No patient suffered from sympathetic ophthalmia. The median initial VA was 2.1 logMAR (n = 11/11). At one month, median VA was 2.0 logMAR (n = 7/11), after three months 2.0 logMAR (n = 6/11), and after one year 2.05 logMAR (n = 6/11). The change in VA was not significant (p > 0.99). 36.4% (n = 4/11) of the cases resulted in blindness. CONCLUSIONS: The overall outcome is poor. Enucleation should be weighed against the risk of local and systemic spread of the infection, prolonged rehabilitation and sympathetic ophthalmia.

Eye injuries from electrical weapon probes: Incidents, prevalence, and legal implications.

PURPOSE: While generally reducing morbidity and mortality, electrical weapons have risks associated with their usage, including burn injuries and trauma associated with uncontrolled fall impacts. However, the prevalence of significant eye injury has not been investigated. METHODS: We searched for incidents of penetrating eye injury from TASER® conducted electrical weapon (CEW) probes via open source media, litigation filings, and a survey of CEW law-enforcement master instructors. RESULTS: We report 20 previously-unpublished cases of penetrating eye injury from electrical weapon probes in law-enforcement field uses. Together with the 8 previously published cases, there are a total of 28 cases out of 3.44 million field uses, giving a demonstrated CEW field-use risk of penetrating eye injury of approximately 1:123 000. Confidence limits [85 000, 178 000] by Wilson score interval. There have been 18 cases of total unilateral blindness or enucleation. We also present legal decisions on this topic. CONCLUSIONS: The use of electrical weapons presents a rare but real risk of total or partial unilateral blindness from electrical weapon probes. Catastrophic eye injuries appear to be the dominant non-fatal complication of electronic control.

Surgical preferences in the management of recalcitrant endophthalmitis.

To assess the practice patterns of current members of the American Society of Ophthalmic Plastic and Reconstructive Surgery (ASOPRS) in the treatment of medically refractive endophthalmitis (MRE). A 17-question survey included the procedure of choice for MRE, the preferred type of orbital implant, the timing of implant placement, and the incidence of postoperative complications. 107 ASOPRS members participated in the study. In the setting of MRE, 72% preferred evisceration versus 28% who preferred enucleation. Fifty-nine percent of responders preferred enucleation if the MRE extended to orbital tissues versus 27% who would eviscerate. Among those that would place an orbital implant at the initial surgery, 65% would do so during an enucleation and 58% would do so during an evisceration. If an orbital implant was placed at the initial surgery, 52% of responders preferred a silicone implant, while 17% preferred hydroxyapatite implant. A minority of responders (6%) reported "yes" to ever having infectious complications after primary enucleation, compared to 10% after primary evisceration. Overall, 12% of responders noted more frequent complications (other than infectious) when an enucleation was performed compared to 5% for eviscerations. Current opinions on the surgical management of MRE show a trend toward evisceration, with 65% of ASOPRS respondents placing an orbital implant at the time of an enucleation and 58% at the time of an evisceration. Enucleation was preferred when involvement of orbital tissues was apparent. Both evisceration and enucleation remain a viable treatment option for MRE. The most appropriate initial approach is best determined by careful patient selection and informed decision-making by the patient.

A decade of surgical eye removals in Ontario: a clinical-pathological study.

OBJECTIVE: To assess patient demographics, clinical indications, and pathologic causes of surgically removed eyes over a decade in Ontario (Canada) and to identify areas of ocular disease management needing more attention. DESIGN: Retrospective cross-sectional study. PARTICIPANTS: The surgically removed eyes of 713 consecutive mainly adult patients from 2004 to 2013. METHODS: Demographic, clinical, and pathologic data were collected on all eyes received by the University of Toronto Ophthalmic Pathology Laboratory from 2004 to 2013. RESULTS: Of the 713 eyes removed, enucleations accounted for 60% of cases, eviscerations for 39% of cases, and exenteration for 1% of cases. The most common clinical indications for surgical eye removal were blind painful eye (37%), neoplasm (35%), and trauma (6%). The leading pathologic causes of eye removal were neoplasm (36%), glaucoma (21%), infection or inflammation (17%), and trauma (16%). Glaucoma-related findings were the most common pathologic findings observed (38%), regardless of the primary cause. CONCLUSIONS: A blind painful eye and neoplasms were the most commonly documented indications prior to removal of the eye. Common pathologies included glaucoma, neoplasms, infection/inflammation, and trauma. However, regardless of the primary cause, glaucoma-related pathologies were the most common pathologic findings. Refractory eye disease and pain continue to be important reasons for removal of eyes among patients in Ontario. More effective and targeted management strategies are needed to reduce the need for this radical eye surgery of last resort.

Indications for eye removal over a 13-year period at an ophthalmology referral center in São Paulo, Brazil.

PURPOSE:: To analyze the indications and types of eye removal at Latin America's highest-volume ophthalmic reference center in São Paulo, Brazil. METHODS:: A retrospective analysis was conducted of surgical pathological reports in the electronic database of the Ophthalmology Department of the Universidade Federal de São Paulo Hospital of patients who underwent eye-removal procedures between January 2000 and December 2012. RESULTS:: A total of 412 cases met the inclusion criteria for this study. The most common indications for eye removal were ocular melanoma and retinoblastoma, representing 35.4% and 31.1% of the total cases, respectively. Other frequent indications included endophthalmitis (6.3%), nonspecific inflammation (4.1%), squamous cell carcinoma (3.6%), panophthalmitis (3.4%), and phthisis bulbi (1.2%). The remaining indications accounted for 14.8% of all cases, with each accounting for <1% of the total cases. Enucleation was the most common eye-removal procedure seen in our study. CONCLUSIONS:: The two most common indications for eye removal were ocular melanoma and retinoblastoma. Alternative treatment options are effective in limiting the need for eye removal but are constrained by our public center's so cioeconomic context.

Indications for enucleation and evisceration in a tertiary eye hospital in Riyadh over a 10-year period.

BACKGROUND: Enucleation and evisceration are eye removal procedures considered as palliative treatment when all other therapeutic options are exhausted. OBJECTIVE: Describe the causes and histopathological findings leading to enucleation/evisceration, and correlate the clinical findings with the histopathological findings. DESIGN: Retrospective, descriptive study. SETTINGS: Tertiary care hospital, Riyadh, Saudi Arabia. PATIENTS AND METHODS: The medical records of patients who underwent enucleation or evisceration from February 2005 to May 2015 were reviewed. Patients were classified into two categories based on indications of surgery: traumatic and nontraumatic. Causes of ocular injury in the traumatic group were documented, and the histopathological findings were reviewed for the nontraumatic cases. MAIN OUTCOME MEASURE(S): Number of enucleation and evisceration surgeries and their causes and histopathological findings. RESULTS: One hundred ten patients underwent evisceration (n=69, 63%) and enucleation (n=41, 37%). Causes were traumatic in 38 (35%) and nontraumatic in 72 (65%). The median age was 50 years and there were 64 men and 46 women. Postoperative endophthalmitis was the most common indication for surgery (n=24, 21.8%), followed by painful blind eye (n=22, 20%). Ocular trauma was more predominant in men (n=29, 76%) than in women (n=9, 24%), and the leading mechanism of trauma was metallic nail injuries (n=6, 15.8%). In the nontraumatic group, endophthalmitis was the most common histopathological finding (n=25, 34.7%). CONCLUSIONS: The majority of the eye enucleation/evisceration surgeries were due to nontraumatic causes, especially postoperative infections. However, severe eye trauma was still a main indication for this destructive procedure. Guidelines are needed to decrease the incidence/severity of work-related eye injuries and to detect and manage eye infections earlier and more promptly. LIMITATIONS: Retrospective study, in one hospital in one area; therefore, results cannot be generalized.

RESUMO Objetivo: Analisar os tipos e indicações para a remoção dos olhos no maior centro de referência oftalmológica da América Latina em São Paulo, Brasil. Métodos: Revisão retrospectiva de laudos cirúrgico patológico em uma base de dados eletrônica do Departamento de Oftalmologia do Hospital da Universidade Federal de São Paulo. Foram analisados pacientes submetidos ao procedimento de remoção oftálmica no período de janeiro de 2000 a dezembro de 2012. Resultados: Um total de 412 casos estiveram de acordo com os critérios de inclusão desse estudo. A indicação mais comum para remoção oftálmica foi Melanoma ocular e Retinoblastoma, representando, respectivamente, 35,4% e 31,1% do total de casos. Outras indicações frequentes incluíam Endoftalmite 6,3%, Inflamação inespecífica 4,1%, Carcinoma escamocelular 3,6%, Panoftalmite 3,4% e Phthisis Bulbi 1,2%. O restante das indicações totalizaram 14,8% de todos os casos, sendo que cada um correspondem com menos de 1% do total. Enucleação foi o procedimento de remoção oftálmica mais comum observado em nosso estudo. Conclusão: As duas indicações mais frequentes para remoção oftálmica no centro oftalmológico de referência do Brasil foi melanoma e retinoblastoma. Opções terapêuticas alternativas são efetivas para limitar a necessidade da remoção ocular, porém são restritos devido ao contexto socioeconômico de nossa população.

Dry Eye Syndrome After Proton Therapy of Ocular Melanomas.

PURPOSE: To investigate whether proton therapy (PT) performs safely in superotemporal melanomas, in terms of risk of dry-eye syndrome (DES). METHODS AND MATERIALS: Tumor location, DES grade, and dose to ocular structures were analyzed in patients undergoing PT (2005-2015) with 52 Gy (prescribed dose, not accounting for biologic effectiveness correction of 1.1). Prognostic factors of DES and severe DES (sDES, grades 2-3) were determined with Cox proportional hazard models. Visual acuity deterioration and enucleation rates were compared by sDES and tumor locations. RESULTS: Median follow-up was 44 months (interquartile range, 18-60 months). Of 853 patients (mean age, 64 years), 30.5% had temporal and 11.4% superotemporal tumors. Five-year incidence of DES and sDES was 23.0% (95% confidence interval [CI] 19.0%-27.7%) and 10.9% (95% CI 8.2%-14.4%), respectively. Multivariable analysis showed a higher risk for sDES in superotemporal (hazard ratio [HR] 5.82, 95% CI 2.72-12.45) and temporal tumors (HR 2.63, 95% CI 1.28-5.42), age ≥70 years (HR 1.90, 95% CI 1.09-3.32), distance to optic disk ≥5 mm (HR 2.71, 95% CI 1.52-4.84), ≥35% of retina receiving 12 Gy (HR 2.98, 95% CI 1.54-5.77), and eyelid rim irradiation (HR 2.68, 95% CI 1.49-4.80). The same risk factors were found for DES. Visual acuity deteriorated more in patients with sDES (0.86 ± 1.10 vs 0.64 ± 0.98 logMAR, P=.034) but not between superotemporal/temporal and other locations (P=.890). Enucleation rates were independent of sDES (P=.707) and tumor locations (P=.729). CONCLUSIONS: Severe DES was more frequent in superotemporal/temporal melanomas. Incidence of vision deterioration and enucleation was no higher in patients with superotemporal melanoma than in patients with tumors in other locations. Tumor location should not contraindicate PT.
