Global, psychological, and visual quality of life after evisceration/enucleation surgery (QOLAE study): A descriptive case series.

PURPOSE: To describe the early health-related quality of life (HRQoL) of patients who have undergone an eye removal surgery. METHODS: A descriptive monocentric study was conducted. Patients with a surgical indication of eye amputation were enrolled. Three standardized surveys were given to each patient 1-3 months after the surgery. The following standardized questionnaires were used: National Eye Institute Visual Function Questionnaire 25 (NEI VFQ-25) (range: 0-100), Short Form-36 (SF-36) (range: 0-100), and Perceived Stress Scale (PSS-10) (range: 0-40). RESULTS: Between January 2021 and January 2022, in the Ophthalmology Department of the University Hospital of Besançon (France), 20 patients who were going to undergo an eye removal surgery were included. The population comprised a majority of men (12 men vs. 8 women) with a mean age of 70 (±16.2) years. The underlying conditions leading to the eye amputation were varied: three infections (15%), three retinal detachments (15%), three chronic uveitis (15%), 11 traumas (55%), three tumors (15%), and five chronic high intraocular pressures (25%). The surgical procedure consisted of an evisceration in 15 cases (75%) or an enucleation in five cases (25%). On average, the composite NEI VFQ-25 scored 68.7 (±22.4). Regarding the SF-36 score, the physical composite score was 63.1 (±15.4), and the mental composite score was 64.7 (±14.4). The overall PSS-10 score was 12.3 (±8.7). CONCLUSION: The patients who had undergone an eye amputation had an early reduction in their HRQoL in all its domains, especially in the vision, mental, and physical specific quality of life. These patients need personalized preparation before the surgery. These findings need to be assessed in the long term.

[Metachronous bilateral retinoblastoma: a case report].

The patient is a 2-year-old male. The family consulted the Department of Ophthalmology, Shanghai Ninth People's Hospital, after noticing a white reflection in the pupil area of the child's right eye for 6 days. Following a thorough ocular and systemic examination, the patient was diagnosed with retinoblastoma (Group E, cT2bN0M0) of the right eye. The right eye was enucleated and classified as pathological stage pT3cN0M0. Postoperatively, systemic intravenous chemotherapy with the VEC regimen was administered. Genetic testing revealed a germline mutation in the RB1 gene: c.874 (exon9) delT (p.Tyr292fsTer9), necessitating close monitoring of the socket during follow-up visits. Three months after the operation, fundus examination revealed yellow-white lesions in the left eye, and bilateral retinoblastoma was diagnosed (Group E in the right eye, Group C in the left eye). Based on the ICRB and pTNM stages, the patient underwent six rounds of systemic intravenous chemotherapy and three rounds of cryotherapy in the left eye. No recurrence was detected with a 4-year follow-up. The patient was initially diagnosed with unilateral retinoblastoma, but later developed the disease in the contralateral eye during treatment, which was a case of metachronous bilateral retinoblastoma.

Clinical outcomes and complications of a new high-density polyethylene-based spherical integrated porous orbital implant.

PURPOSE: To describe our experience over 6 years using a new high-density polyethylene-based spherical integrated porous orbital implants (Oculfit). METHODS: This is an observational retrospective case series study analyzing all cases requiring Oculfit implants between February 2015 and September 2021. Clinical information regarding the population included, the characteristics of the implant, and the outcomes and complications during the follow-up were noted. The success of the implant was defined according to anatomical and functional parameters. RESULTS: The study analyzed 90 cases of anophthalmic patients. The main causes for enucleation or evisceration were ocular decompensations (36.7%) and neoplasms (27.8% uveal melanoma and 7.8% retinoblastoma). Anatomical success was identified in 63 (70.0%) cases, functional success in 79 (87.8%) and complete success (anatomical + functional) in 61 (67.7%) cases. Factors associated with the functional success were age and exposure of the primary orbital implant. Complications appeared in 11 (12.2%) cases, which were completely resolved without sequelae in 4 (4.4%). Orbital explant was required in 5 (5.6%) cases. CONCLUSION: In our experience, Oculfit can be considered a useful alternative among the currently available options for orbital implants and has a good efficacy/safety profile.

Outcome of Retinoblastoma After Implementation of National Retinoblastoma Treatment Guidelines in South Africa.

PURPOSE: Retinoblastoma, a curable childhood cancer, has been identified as a tracer cancer in the WHO Global Initiative for Childhood Cancer. To document the outcomes of children with retinoblastoma in South Africa, treated as per the first prospective standard national treatment guidelines for childhood cancer in South Africa. PATIENTS AND METHODS: All children diagnosed with retinoblastoma between 2012 and 2016 in five South African pediatric oncology units were treated with a standard treatment on the basis of the International Society of Pediatric Oncology-Pediatric Oncology in Developing Countries guidelines for high-income settings. Treatment included focal therapy with/without chemotherapy, or enucleation with/without chemotherapy, and orbital radiotherapy, depending on enucleated eye histology. The end point was survival at 24 months, using Kaplan-Meier curves with log-rank (Mantel-Cox) and chi-square (χ2) tests with respective P values reported. RESULTS: A total of 178 children were included in the study; 68% presented with unilateral disease. The median age was 27 months (range 0-118 months) with a male:female ratio of 1:0.75. The overall survival was 79% at 24 months with significant association with stage at diagnosis (P < .001) and older age over 2 years as opposed to younger than 2 years (P < .001). Causes of death were disease progression/relapses in 90% (34 of 38) and unknown in 2% (1 of 38), whereas treatment abandonment was 1.7% (3 of 178). CONCLUSION: Efficacy with national treatment guidelines was confirmed, and feasibility of implementing standard national childhood cancer treatment guidelines was documented, involving multidisciplinary teams in South Africa. Outcome was significantly associated with stage at diagnosis and age.

Experience Dependence of Alpha Rhythms and Neural Dynamics in the Mouse Visual Cortex.

The role of experience in the development and maintenance of emergent network properties such as cortical oscillations and states is poorly understood. To define how early-life experience affects cortical dynamics in the visual cortex of adult, head-fixed mice, we examined the effects of two forms of blindness initiated before eye opening and continuing through recording: (1) bilateral loss of retinal input (enucleation) and (2) degradation of visual input (eyelid suture). Neither form of deprivation fundamentally altered the state-dependent regulation of firing rates or local field potentials. However, each deprivation caused unique changes in network behavior. Laminar analysis revealed two different generative mechanisms for low-frequency synchronization: one prevalent during movement and the other during quiet wakefulness. The former was absent in enucleated mice, suggesting a mouse homolog of human alpha oscillations. In addition, neurons in enucleated animals were less correlated and fired more regularly, but no change in mean firing rate. Eyelid suture decreased firing rates during quiet wakefulness, but not during movement, with no effect on neural correlations or regularity. Sutured animals showed a broadband increase in depth EEG power and an increased occurrence, but reduced central frequency, of narrowband gamma oscillations. The complementary-rather than additive-effects of lid suture and enucleation suggest that the development of emergent network properties does not require vision but is plastic to modified input. Our results suggest a complex interaction of internal set points and experience determines mature cortical activity, with low-frequency synchronization being particularly susceptible to early deprivation.

A modified supraorbital surgical approach for enucleation- exenteration in dromedary camels (camelus dromedarius): Clinical study.

Enucleation and exenteration are widely utilized ophthalmic procedures in veterinary field. Enucleation in camels is like other large animals, typically performed under the influence of heavy sedation and loco-regional analgesia. The aim of the current study was to introduce a new surgical approach to enucleate the eye of camels through supraorbital fossa approach. for that purpose, the technique was applied to seven camels referred to the King-fisal teaching veterinary hospital for unilateral enucleation. Assessment of applicability, safety and feasibility of this technique was done. All procedures were performed in the kush (sitting) position under the influence of heavy sedation with Xylazine HCl in combination with retrobulbar nerve block. A "C" shaped skin incision was made in the skin and fascia of the supraorbital fossa to enter the orbital cavity, after which the periorbital fat was gripped, dissected and removed. Bleeding controlled by electrocautery and visible large blood vessels were ligated. After ligation the optic nerve and ophthalmic blood vessels, the eyeball was dissected sharply and freed from the orbital bony attachment. Finally, the orbital fascia and skin were sutured with simple interrupted pattern separately. The approach proved successful in all camels, with the enucleation procedure being both feasible and easily performed. The mean surgical time was approximately 46.6±12.4 minutes. The minimal occurrence of short and long-term complications was encouraging, and the cosmetic outcomes were notably improved. The supraorbital approach is a safe and effective technique for camel ophthalmic surgery, showing advantages in exposure and minimal complications. Further research is needed for validation and broader clinical applications.

Pathological findings in enucleated eyes of patients with neurofibromatosis type 1: report of a case with 15-year follow-up and review of 14 patients in the literature.

BACKGROUNDS: Iris nodules are frequently noted as clinical manifestations of neurofibromatosis type 1 but the other intraocular manifestations are rare. The purpose of this study is to present a patient with a phthisic eye who underwent enucleation for a cosmetic reason after 15-year follow-up and also to review 14 patients with enucleation described in the literature. CASE PRESENTATION: A 17-year-old man with neurofibromatosis type 1 from infancy underwent the enucleation of phthisic left eye and also had the resection of eyelid subcutaneous mass lesions on the left side for a cosmetic reason. He had undergone four-time preceding surgeries for eyelid and orbital mass reduction on the left side in childhood and had developed total retinal detachment 10 years previously. Pathologically, the enucleated eye showed massive retinal gliosis positive for both S-100 and glial fibrillary acidic protein (GFAP) in the area with involvement of the detached retinal neuronal layer, together with a more fibrotic lesion along the choroid which were, in contrast, negative for both S-100 and GFAP. The choroid, ciliary body, and iris did not show apparent neurofibroma while episcleral neurofibroma was present. LITERATURE REVIEW: In review of enucleated eyes of 14 patients in the literature, buphthalmic eyes with early-onset glaucoma on the unilateral side was clinically diagnosed in 9 patients who frequently showed varying extent of hemifacial neurofibromatosis which involved the eyelid and orbit on the same side. Pathologically, neurofibromas in varying extent were found in the choroid of 12 patients. One patient showed choroidal malignant melanoma on the left side and fusiform enlargement of the optic nerve on the right side suspected of optic nerve glioma. The phthisic eye in another patient showed massive retinal gliosis similar to the present patient. CONCLUSIONS: In summary of the 15 patients with neurofibromatosis type 1, including the present patient, buphthalmic or phthisic eyes with no vision were enucleated for cosmetic reasons and showed choroidal neurofibroma in most patients and massive retinal gliosis in two patients including the present patient.

Clinical characterization and long-term postoperative outcomes of retinoblastoma patients receiving enucleation and primary orbital implantation in early infancy: an observational study.

OBJECTIVES: To retrospectively investigate clinical characterization and the long-term postoperative outcomes of retinoblastoma (RB) patients receiving enucleation with primary orbital implantation in early infancy (0-6 months old). METHODS: The clinical and follow-up data of 42 RB patients receiving enucleation with primary orbital implantation in early infancy at Beijing Tongren Hospital from December 2009 to January 2020 were analysed. The average follow-up time was 83 months. The patient group included 24 males and 18 females, 30 unilateral and 12 bilateral cases. A total of 44 eyes with 10 in stage D and 34 in stage E underwent 40 unilateral and 2 bilateral surgeries. 17 RB eyes received hydrogel and 27 RB eyes received hydroxyapatite implants. This study was performed by following the guideline of STROBE. RESULTS: Enucleation combined with primary orbital implantation promoted survival and was safe with few and minor complications such as increased secretion, upper eyelid ptosis, and sunken eye sockets which were not affected by stages, lateralities, or implant materials. 55-80% RB patients exhibited satisfactory appearance and obvious or moderate motility of orbital implants according to the evaluation by doctors and family members. Family members were likely more optimistic about the appearance and more pessimistic about motility of the orbital implantation than doctors did.The quality of life was high as indicated by PedsQL3.0 or PedsQL4.0 scores ( ≧ 90 for > 75% patients). It was not affected by the stages, laterality, and implant materials, nor affected by the appearance and motility of the implants. CONCLUSIONS: The outcomes of the combination of enucleation and primary orbital implantation for pertinent RB patients in early infancy are generally satisfactory with few and minor complications, high safety, appearance, and overall quality of life. Enucleation combined with primary orbital implantation in early infancy benefits pertinent RB patients in appearance, survival, and quality of life.

Effects of early monocular enucleation on cortical spreading depression in well-nourished and malnourished adult rats.

Sensory development is a complex process that can influence physiological and pathological factors. In laterally-eyed mammals, monocular enucleation (ME) during development and the subsequent lack of external sensory stimuli can result in permanent morphological and physiological changes. Malnutrition, especially in early life, also can cause permanent morphofunctional changes due to inadequate nutrient intake in both hemispheres. This study investigated the effects of early (postnatal day 7) ME and malnutrition during the suckling period on cortical excitability in adulthood (110-140 days of life). For this, we compared the speed propagation of cortical spreading depression in the occipital and parietal cortex of malnourished and well-nourished adult rats, previously suckled small-sized litters with three pups (L3/dam) medium-sized litters with six pups (L6/dam), and large-sized litters with twelve pups (L12/dam). The CSD velocity was augmented by the ME in the contralateral side of the removed eye in the parietal and occipital cortex. These findings suggest that visual sensory input deprivation is associated with permanent functional changes in the visual pathways, which can alter cortical excitability and lead to modifications in CSD propagation.

Visualization of distribution in the vitreous cavity via eye drops using ultra-heavily T2-weighted sequences in MRI: a preliminary study with enucleated pig eyes.

We investigated whether magnetic resonance imaging can visualize the distribution in the vitreous cavity via eye drops of ophthalmic solutions, gadolinium-based contrast agent, and 17O-water, and to clarify the usefulness of ultra-heavily T2-weighted sequences in the research of intraocular distribution. Five different solutions (V-ROHTO, TRAVATANZ, gadobutrol, H217O, and saline) were administered to excised pig eye specimens. The samples were scanned using T1 mapping, T2 mapping, 3D T2-weighted (echo times (TE): 500, 3200, and 4500 ms), a half-Fourier single-shot turbo-spin echo sequence (HASTE; TE: 440 and 3000 ms), and 3D-real inversion-recovery before eye drops administration. Subsequently, we used a plastic dropper to drop a 0.5 mL solution each, and images were obtained up to 26 h later. Temporal changes in the T1 and T2 values of the anterior chamber and vitreous cavity were compared. The other sequences were evaluated by determining temporal signal changes as signal intensity ratio (SIR) compared to "No drop." The T1 and T2 values of samples treated with gadobutrol and H217O decreased over time. The SIR of samples treated with gadobutrol and H217O showed remarkable changes in the 3D T2-weighted images, whereas no remarkable temporal changes were observed in the other solutions. Longer TEs resulted in remarkable changes. We demonstrated that visualization of distribution in the vitreous cavity via eye drops could be achieved with excised pig eyes using gadobutrol and H217O, but not with ophthalmic solutions. Ultra-heavily T2-weighted sequences may be promising for the early and highly sensitive visualization of the intraocular distribution of eye drops.

A retrospective study on adjuvant chemotherapy in retinoblastoma: validation of the new recommendation against treatment for pT2a tumors based on the 8th AJCC classification.

BACKGROUND: Retinoblastoma (RB) is an intraocular malignant tumor detected in early childhood with variable global impact. Histopathological classification of the tumor in enucleated globes with RB is the key for the decision of adjuvant chemotherapy use. We aim to validate the use of adjuvant chemotherapy in cases with combined pre-laminar/intralaminar optic nerve (ON) invasion and focal choroidal invasion according to the American Joint Committee on Cancer (AJCC) 8th classification. METHODS: This is a retrospective study conducted at King Abdulaziz University Hospital (KAUH) and King Khalid Eye Specialist Hospital (KKESH) in Riyadh, Saudi Arabia of all RB cases who underwent enucleation over 22 years (2000 to 2021). The histopathological findings were reviewed to identify the enucleated globes classified as pT2a tumors, as an inclusion criterion. Basic demographic and clinical data were collected via chart review Simple descriptive and basic statistical analysis of the data was used where applicable. RESULTS: Thirty-one patients who had an enucleated globe with RB that fit into the above classification were included. Sixteen were males and 15 were females. The median age was 14 months (IQR = 14 months). Most of the patients (93.5%) had no family history of RB. The commonest presentation was leukocoria in 87.1% followed by squint in 32.3%. Fourteen patients (45.2%) were treated by enucleation alone while 17 patients (54.8%) received adjuvant chemotherapy. Out of these, 7 patients had unilateral RB and the remaining 10 patients had bilateral RB. None of our patients developed recurrence or metastatic disease irrespective of the indication for adjuvant chemotherapy use after a maximum period of follow up reaching 17.84 years and a median of 10.6 years (IQR = 5.92). CONCLUSIONS: In patients with 8th AJCC histopathological classification of pT2a, chemotherapy following enucleation might not be justified. The outcome in our untreated group of patients did not differ from the treated group with the absence of metastasis after a relatively long period of follow up with a median exceeding 10 years in both groups. Therefore, the risk and benefit of post enucleation adjuvant chemotherapy in the treatment of unilateral RB should be carefully decided and discussed with the primary caregivers taking into consideration the most recent evidence and recommendations in the literature.

Evolving criteria for group E retinoblastoma: impact on outcomes.

OBJECTIVE: To assess the impact of evolving criteria for group E retinoblastoma on ocular survival outcomes. DESIGN: A retrospective observational study. METHODS: Single-institution consecutive case series of patients with advanced intraocular retinoblastoma (groups D and E) were classified based on International Intraocular Retinoblastoma Classification (IIRC) and International Classification of Retinoblastoma (ICRB) criteria. The main outcomes measured were ocular survival, frequency of histopathologic risk factors (HRF), and the need for adjuvant therapy. RESULTS: A total of 332 eyes of 298 patients were classified into group D (150, 45%) and E eyes (182, 55%) based on IIRC criteria. ICRB classification resulted in upstaging of 57 group D eyes (17%) to group E. Eyes that were upstaged to group E from D in the ICRB classification (E1) differed significantly, with a greater proportion undergoing primary enucleation (17 of 57, 30%) than those that were not (10 of 93, 11%) (p = 0.003). Similar significant differences were observed between group E2 and E3 eyes (p < 0.0001). Ocular survival according to Kaplan-Meier estimates at 12 months of 79%, 59%, 49%, and 1% differed significantly between all groups (ICRB D, E1, E2, and E3, respectively). CONCLUSION: Proposed new subgrouping of group E eyes into E1, E2, and E3 based on clinical criteria is based upon natural history of tumor progression and is predictive of ocular survival. Preservation of the existing lower boundaries for group E by ICRB and IIRC offers the possibility of reanalyzing existing published data.

Long-Term Outcomes of Enucleation and Secondary Orbital Implantation Surgeries Using Polyester Mesh-Wrapped Acrylic Orbital Implants.

OBJECTIVE: To reveal the long-term outcomes of enucleation and secondary orbital implantation surgeries employing nonabsorbable surgical mesh-wrapped acrylic orbital implants for various reasons. METHODS: A retrospective interventional study of 48 eyes that underwent primary or late primary enucleation and secondary orbital implantation using polyester mesh-wrapped acrylic orbital implants, between 2012 and 2021. Patient demographics, diagnosis, prior ophthalmic surgery, implant size, follow-up periods, and implant-associated complications were evaluated. RESULTS: The records of 36 patients who underwent primary or late primary enucleation and 12 who underwent secondary orbital implantation due to sphere extrusion were evaluated. Patients' mean age was 38.7 (range: 2-75) and the mean follow-up period was 48.3 months (range: 24-72 mo). Major causes for surgeries were trauma and malignancies (54.1% and 33.3%, respectively). No complications, such as conjunctival dehiscence, implant exposure or extrusion, contracted socket, or fornix insufficiency were observed in any patient during the long-term follow-up period postsurgeries. CONCLUSION: Using polyester mesh-wrapped acrylic orbital implants in enucleation and secondary orbital implantation surgeries proves to be a successful, safe, and cost-effective option.

Report of endophthalmitis caused by Paradictyoarthrinium diffractum after plant trauma: A case involving left enucleation.

During outdoor work in April 2022, a 48-year-old man was stabbed by a tree branch and underwent intraocular foreign body extraction and repair of the scleral wound with sutures and amniotic membrane graft at a local hospital. Steroid therapy with prednisone was prescribed after a diagnosis of uveitis. Vitrectomy was performed in June 2023; a fungal culture was positive, and ITS sequencing identified the organism as Paradictyoarthrinium diffractum. Empiric antifungal therapy did not have an effect, and, because of deterioration of the condition, the left eye was enucleated in October 2023. P. diffractum is a mangrove host-specific saprophytic fungus that has not been reported in humans.

A case of accidental self-enucleation caused by obstructive sleep apnea.

A novel form of injury associated with obstructive sleep apnea (OSA) that was comorbid with obesity hypoventilation syndrome and severe daytime somnolence is reported in a 55-year-old woman, manifesting as severe ocular and extraocular muscle injuries sustained from suddenly falling asleep and colliding with a sharp object, resulting in surgical enucleation of the right eye and orbital implant. The literature on injuries (falls, motor vehicle accidents) related to OSA and excessive day time sleepiness is reviewed, along with the literature on injuries from OSA-related parasomnias. The diverse health hazards, including physical injury, associated with OSA-excessive daytime sleepiness, are emphasized, further encouraging the need to educate primary care providers on early detection of OSA with prompt treatment intervention. CITATION: Baker N, Schenck CH, Golden E, Varghese R. A case of accidental self-enucleation caused by obstructive sleep apnea. J Clin Sleep Med. 2024;20(8):1395-1397.

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.

Amniotic Membrane Augmentation for Enucleation After Chemotherapy in Retinoblastoma.

PURPOSE: To describe amniotic membrane augmentation for enucleation after chemotherapy in retinoblastoma. METHODS: This was a retrospective study of patients with retinoblastoma who underwent enucleation. The study also evaluated the utility of amniotic membrane grafting in enucleation after chemotherapy in eyes with retinoblastoma. RESULTS: In this study, 110 eyes of 107 patients were analyzed, and 49 patients had previous systemic chemotherapy, 13 eyes had previous intra-arterial chemotherapy, and 7 eyes had external beam radiation. Amniotic graft was used in 8 eyes (5 following IAC, 2 following systemic chemotherapy, and 1 after both). After IAC, 3 of 7 eyes without amniotic graft had implant exposure compared to 0 of 6 eyes with amniotic graft (P = .05). Pathological examination of the conjunctiva after intra-arterial chemotherapy showed goblet cell hypoplasia that hinders wound healing. CONCLUSIONS: Amniotic membrane augmentation improves wound integrity in patients with retinoblastoma, especially following intra-arterial chemotherapy.

Postoperative Pain Following Eye Enucleation: A Prospective Observational Study.

Background and Objectives: Enucleation of an eye is the most invasive procedure in ophthalmologic surgery. It can be the result of various diseases (malignant/chronic/trauma/infection) and is nevertheless relatively rare, but leads to the loss of a strongly innervated neuronal organ. This study systematically evaluates postoperative pain levels following enucleation of the eye globe. Materials and Methods: This prospective single-center study enrolled twenty-four patients undergoing enucleation of the eye globe. Perioperatively all patients completed (preoperative day, day of surgery, 1st, 2nd, and 3rd day following surgery) standardized questionnaires concerning their pain experience and treatment-related side-effects (internal protocol, QUIPS, painDETECT®). Patients received usual pain therapy in an unstandardized individual manner. Results: Preoperatively, mean average pain intensity of all included patients was 3.29 ± 2.46 (range, 0-8), 3.29 ± 3.24 (range, 0-8) on the day of surgery, 4.67 ± 1.90 (range, 2-10) on day 1, 3.25 ± 1.39 (range, 1-6) on day 2, and 2.71 ± 1.30 (range, 1-6) on day 3 after surgery. Mean maximum pain intensity was 4.71 ± 3.28 (range, 0-10) preoperatively, 4.04 ± 3.78 (range, 0-10) on the day of surgery, 5.75 ± 2.01 (range, 2-10) on day 1, 4.25 ± 1.89 (range, 2-10) on day 2, and 3.88 ± 1.54 (range, 2-8) on day 3 after surgery. Nineteen patients (79.2%) stated that they would have preferred more pain therapy. Conclusions: Patients undergoing eye enucleation report pain sensations in need of intervention in this university hospital. Thus, effective standardized pain treatment concepts are now a high priority to be established in an interdisciplinary manner containing standardized regimens and continuous regional procedures. Awareness of this problem in the medical team should be sharpened through targeted training and information.
