RESUMO

PURPOSE: To compare standard and total corneal astigmatism measurements to the predicted pseudophakic (nontoric) refractive astigmatism in candidates for cataract surgery. DESIGN: A retrospective, cross-sectional study. METHODS: A single-center analysis of consecutive eyes measured with a swept-source optical coherence tomography biometer at a large tertiary medical center between February 2018 and June 2020. Corneal astigmatism was calculated based on standard keratometry astigmatism (KA), total corneal astigmatism (TCA), and predicted refractive astigmatism (PRA) for a monofocal nontoric intraocular lens (IOL) implantation calculated by the Barrett toric calculator using the predicted posterior corneal astigmatism (PRA(Predicted-PCA)) and the measured posterior corneal astigmatism (PRA(Measured-PCA)) options. Separate analyses were performed for each eye. SETTING: Ophthalmology Department, Shaare Zedek Medical Center, Jerusalem, Israel. RESULTS: In total, 8152 eyes of 5320 patients (4221 right eyes [OD] and 3931 left eyes [OS], mean age 70.6±12.2 years, 54.2% females) were included in the study. The mean vector values (centroid) for KA, TCA, PRA(Predicted-PCA), and PRA(Measured-PCA) were 0.07 diopters [D] at 19.5°, 0.27 D at 7.5°, 0.44 D at 2.9°, and 0.43 D at 179.3°, respectively (P < .01), for OD and 0.02 D at 150.3°, 0.23 D at 169.7°, 0.40 D at 179.4°, and 0.42 D at 169.5°, respectively (P < .01), for OS. More than 73% of eyes had a PRA >0.5 D. CONCLUSIONS: Standard and total corneal astigmatism measurements differ significantly from the PRA by the Barrett toric calculator. The PRA, rather than the KA or TCA, should be used as the reference guide for astigmatism correction with toric IOL implantation.

RESUMO

PURPOSE: To compare calculated corneal surgically induced astigmatism (SIA) by means of anterior-based keratometry (K) and total keratometry (TK) measurements made by 2 biometric devices. SETTING: Ophthalmology Department, Shaare Zedek Medical Center, Jerusalem, Israel. DESIGN: Retrospective, consecutive case series. METHODS: The medical records of patients who had undergone cataract surgery through a 2.4 mm temporal clear corneal incision by a single surgeon between March 2018 and November 2020 were retrospectively reviewed. Patients for whom there were preoperative and postoperative K measurements assessed by 2 biometric devices, optical low-coherence reflectometry (OLCR) (Lenstar LS900, Haag-Streit, software v. eye suite i/9.1.0.0) and swept-source optical coherence tomography (SS-OCT) (IOLMaster700, Carl Zeiss Meditec AG, software v. 1.80.6.60340), were identified. Corneal SIA (mean vector value) was calculated by vector analysis for 3 groups: SS-OCT(K), SS-OCT(TK), and OLCR(K). Bivariate analyses were applied for comparisons. RESULTS: 147 eyes of 123 patients (73 right eyes and 74 left eyes) were enrolled in the study. The right eye corneal SIA values were 0.09 diopters (D) @ 136 degrees, 0.09 D @ 141 degrees, and 0.07 D @ 123 degrees for the SS-OCT(K), SS-OCT(TK), and OLCR, respectively. The corresponding left eye corneal SIA values were 0.13 D @ 120 degrees, 0.11 D @ 123 degrees, and 0.08 D @ 120 degrees. There were no statistically significant differences between the mean vector value and variance of the corneal SIA for the right (P = .78 and P = .65) and the left (P = .75 and P = .37) eyes of the 3 groups. CONCLUSIONS: Corneal SIA values were low (0.07 to 0.13 D) and similar for the SS-OCT and the OLCR biometric devices with standard K measurements. TK measurements yielded similar corneal SIA values compared with anterior corneal-based measurements.

RESUMO

OBJECTIVE: This study presents the results of an updated clinical protocol for orbital blow-out fractures, with a special emphasis on nonsurgical treatment and orthoptic evaluation of functional improvement. METHODS: A two-centre multidisciplinary prospective cohort study was designed to monitor the results of a clinical protocol by assessing ductions, diplopia, globe position, and fracture size. Patients underwent clinical assessment and orthoptic evaluation at first presentation and then at 2 weeks and 3/6/12 months after nonsurgical or surgical treatment. Outcome parameters were field of binocular single vision (BSV), ductions, degree of enophthalmos, a diplopia quality-of-life (QoL) questionnaire, and other sequelae or surgical complications. RESULTS: 46 of the 58 patients who completed the 3, 6 and/or 12-month follow-up received nonsurgical treatment. There was full recovery without diplopia or enophthalmos (>2 mm) in 45 of the 58 patients. The other 13 patients had limited diplopia, mainly in extreme upward gaze (average BSV 90). Five of those 13 patients did not experience impairment of diplopia in daily life. The average QoL score at the end of follow-up was 97. No patients developed late enophthalmos. CONCLUSION: This study showed that a high percentage of patients with orbital floor and/or medial wall fracture recovered spontaneously without lasting diplopia or cosmetically disfiguring enophthalmos. The conservative treatment protocol assessed here underlines the importance of orthoptic evaluation of functional parameters.

RESUMO

PURPOSE: To correct peripapillary retinal nerve fibre layer (pRNFL) measurements performed with spectral domain optical coherence tomography (SD-OCT) for low image quality factor (QF) in patients with cataract, using measurements before and after cataract surgery. METHODS: SD-OCT (Topcon 3DOCT-2000) volume scans of the optic disc of 13 cataract patients were used. A set of three reflective filters with optical density ranging from 0.11 to 0.54 were used. The correlation was calculated between the change in thickness measurements and the change in image quality factor. Changes before and after cataract surgery were analysed. A correction for scans with a lower QF was calculated using an equation which was formulated based on the relationship between the change in thickness measurements and the change in image quality factor. RESULTS: Thirteen right eyes of thirteen cataract patients were included in this study. pRNFL thickness measurements before and after cataract differed significantly (96 versus 99 micron, p < 0.01). Preoperative linear regression lines showed a different slope than postoperative regression lines. Corrected pRNFL thickness measurements of before cataract surgery differed significantly with pRNFL thickness measurements after cataract surgery. CONCLUSIONS: The presence of cataract influences the QF-pRNFL relationship. The lower the image QF, the higher the pRNFL thickness underestimation. We found a rather curvilinear relationship between QF and pRNFL. Our corrected measurements of the pRNFL thickness in case of lower image QF due to cataract still differed significantly from the pRNFL thickness measurements after cataract surgery.

RESUMO

Non-Hodgkin orbital lymphoma (NHOL) and idiopathic orbital inflammation (IOI) are common orbital conditions with largely unknown pathophysiology that can be difficult to diagnose. In this study we aim to identify serum miRNAs associated with NHOL and IOI. We performed OpenArray® miRNA profiling in 33 patients and controls. Differentially expressed miRNAs were technically validated across technology platforms and replicated in an additional cohort of 32 patients and controls. We identified and independently validated a serum miRNA profile of NHOL that was remarkably similar to IOI and characterized by an increased expression of a cluster of eight miRNAs. Pathway enrichment analysis indicated that the miRNA-cluster is associated with immune-mediated pathways, which we supported by demonstrating the elevated expression of this cluster in serum of patients with other inflammatory conditions. The cluster contained miR-148a, a key driver of B-cell tolerance, and miR-365 that correlated with serum IgG and IgM concentrations. In addition, miR-29a and miR-223 were associated with blood lymphocyte and neutrophil populations, respectively. NHOL and IOI are characterized by an abnormal serum miRNA-cluster associated with immune pathway activation and linked to B cell and neutrophil dysfunction.

RESUMO

PURPOSE: To describe the natural course of orbital fat volume and extraocular muscle volume in mild Graves orbitopathy during a 4-year follow-up. To describe fatty changes within the extraocular muscles. PATIENTS: Twenty-five patients with mild Graves orbitopathy, who did not require any therapeutic intervention other than supportive therapy, were followed for 4 years. METHODS: CT scans were performed in all patients at baseline and follow-up. A validated technique using Mimics (Materialise) was used to calculate fat and muscle volumes. Outcomes were compared with previously collected data. The amount of intramuscular fat was assessed on CT scans in a semi-quantitative way by two blinded observers according to a four-point scale. RESULTS: After a median follow-up of 4.3 years, the median fat to orbital volume ratio increased with 0.08 from 0.57 to 0.65 (p = 0.000), whereas the median muscle volume to orbital volume ratio decreased with 0.03 from 0.17 to 0.14 (p = 0.000). In this control group in patients between 49 and 54 years old, the changes were 0.01 and -0.002, respectively. The Clinical Activity Score decreased to zero (p = 0.000), and the median eyelid aperture decreased from 12 to 10 mm (p = 0.007). A significant increase of intramuscular fat was found in patients with Graves orbitopathy. CONCLUSIONS: The natural course of mild Graves orbitopathy, as observed over 4 years, is characterized by an increase of orbital fat volume, a decrease in muscle volume, and an increased intramuscular fatty degeneration.

RESUMO

PURPOSE: To evaluate the accuracy of different intraocular lens (IOL) power calculation formulas available on the American Society of Cataract and Refractive Surgery calculator in calculating multifocal IOL power in eyes with previous hyperopic corneal refractive laser surgery. DESIGN: Retrospective case series. SETTING: Amsterdam University Medical Center, University of Amsterdam, and Retina Total Eye Care, Driebergen, the Netherlands. METHODS: This study compared the accuracy of 3 formulas using historical refractive data (ie, Masket, modified Masket, and Barrett True-K) and 3 formulas using no previous refractive data (ie, Shammas, Haigis-L, and Barrett True-K no-history). RESULTS: Sixty-four eyes were included. The variance of the prediction error of the various formulas was similar and ranged from 0.27 D2 to 0.33 D2 (P = .99). The modified Masket formula had a significantly higher median absolute prediction error than the Masket formula, Barrett True-K formula, and mean value of all formulas (P < .001). CONCLUSION: All formulas showed comparable accuracy in predicting IOL power in eyes after hyperopic corneal refractive laser surgery except for the modified Masket formula, which performed less accurately than the Masket formula, Barrett True-K formula, and mean value of all formulas.

RESUMO

PURPOSE: To compare the accuracy of different intraocular lens (IOL) calculation formulas available on the American Society of Cataract and Refractive Surgery (ASCRS) post-refractive surgery IOL power calculator for the prediction of multifocal IOL power after previous corneal refractive laser surgery for myopia. METHODS: An analysis and comparison were performed of the accuracy of three methods using surgically induced change in refraction (ie, Masket, Modified Masket, and Barrett True-K formulas) and three methods using no previous data (ie, Shammas, Haigis-L, and Barrett True-K No History formulas). The average of all formulas was also analyzed and compared. RESULTS: Thirty-six eyes of 36 patients were included. All formulas, except for the Masket, Modified Masket, and Barrett True-K formulas, had myopic mean numerical errors that were significantly different from zero (P ⩽ .01). The median absolute error of the Shammas formula (0.52 diopters [D]) was significantly higher compared to all of the other formulas (P < .05), except for the Haigis-L formula (P = .09). Comparing the formulas using no previous data, the Barrett True-K No History formula had the lowest median absolute error (0.33 D, P < .001). CONCLUSIONS: The Shammas formula showed the least accuracy in predicting IOL power in eyes with multifocal IOL implantation after previous corneal refractive laser surgery for myopia. In eyes with all available data, all formulas performed equally except for the Shammas formula, whereas in eyes lacking historical data, the Barrett True-K No History formula performed best.

RESUMO

Purpose: To present nine new cases of superior ophthalmic vein thrombosis (SOVT) and compare these with the literature, and to assess the impact of SOVT for the clinician. Methods: Using the data bases of the Department of Ophthalmology of the AMC, we searched for patients with radiologically evidenced SOVT between January 2006 and December 2014. In addition, a PubMed search, using the mesh term 'superior ophthalmic vein thrombosis', was done. Results: We found nine patients with SOVT. In three patients, SOVT was related to dural arteriovenous fistulae. In one patient, it was caused by the acute reversal of warfarin by vitamin K. In two patients, an infectious cause was found. In three patients, the cause of SOVT was not found despite screening for coagulation and other disorders. All patients presented with eyelid swelling, proptosis, and/or motility impairment. We found complete recovery in four patients. Three patients had mild sequelae and two patients had severe visual impairment. In the literature, we found 60 cases reporting on SOVT with various aetiologies. Clinical presentation, treatment modalities, and outcomes were comparable to our findings. Conclusion: Our case series and literature review show that SOVT can occur simultaneously with cavernous sinus thrombosis (CST) but can also be a separate entity. Clinical presentation can mimic orbital cellulitis (OC) or CST and when no signs of OC can be found, an alternative cause for SOVT should be sought. When timely and adequate treatment is conducted, the prognosis is predominantly favourable.

RESUMO

PURPOSE: Septic cavernous sinus thrombosis (CST) is a rare complication of infections in the head and neck area. CST is notorious for its bad prognosis, with high mortality and morbidity rates described in literature. However, these rates are based on old series. We question whether the prognosis of CST is currently still as devastating. The primary purpose of this study is to assess the mortality and morbidity of CST. METHODS: Using the databases of all relevant specialties in our tertiary referral hospital, we collected all the patients treated for CST in the period 2005-2017. In addition, a PubMed search, using the mesh term 'cavernous sinus thrombosis', was performed. RESULTS: We found 12 patients with CST in the study period. Of the 12 patients, 11 survived and 9 recovered without any permanent deficits. Seven patients were treated with anticoagulation, and in none of the patients we saw hemorrhagic complications. In literature, older articles describe higher mortality rates (14-80%), but more recent articles report mortality and morbidity rates similar to our results. CONCLUSIONS: The prognosis of CST nowadays is more favorable than previously described. Anticoagulation seems to be a safe addition to antibiotic and surgical treatment, at least in patients without central nervous system infection.

RESUMO

BACKGROUND: Cosmetic dissatisfaction, pain, and chronic discharge may present months till years after enucleation in patients operated because of retinoblastoma. If noninvasive treatment modalities are insufficient, socket reconstruction can be considered. In this study, we discuss the results of dermis-fat exchange to treat these problems. METHOD: Four patients with late onset post enucleation socket problems with a request for treatment were included in this prospective study. Socket inspection was documented and pictures at baseline and at a follow-up of at least 6 months were taken. To quantify the problem 'pain', a VAS score at baseline and at follow up was used. For the problem 'cosmetic dissatisfaction' standardized questionnaires were used. RESULTS: Two patients were included because of cosmetic dissatisfaction; one was included with chronic pain and one with chronic discharge. Reconstruction of the socket using autologous dermis-fat insertion was done in all four. In one of them, severe shrinking of the fat developed. This patient was treated with additional injectable fillers. Both of them, ultimately, had satisfactory results. Autologous fat transplantation also solved the problem of chronic discharge and pain in the two other patients. CONCLUSION: Socket reconstruction by autologous dermis-fat exchange may solve different post enucleation socket problems. However, shrinking of the transplanted fat may occur and require additional procedures.

RESUMO

PURPOSE: To describe the outcomes in terms of the refraction and visual acuity of multifocal intraocular lens (IOL) implantation in patients with previous hyperopic corneal refractive laser surgery. SETTING: Academic Medical Center, University of Amsterdam, Amsterdam, and Retina Total Eye Care, Driebergen, the Netherlands. DESIGN: Retrospective case series. METHODS: Results were analyzed 3 months after implantation of a multifocal IOL (Acrysof Restor SN6AD1) in patients after previous corneal refractive laser surgery for hyperopia. The primary outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and refraction. The secondary outcome measures were the number of laser enhancements and posterior capsule opacification (PCO) rates. RESULTS: Forty eyes of 40 patients were included. Sixteen eyes (40.0%) had lens extraction because of cataract, and 24 eyes (60.0%) had refractive lens exchange. The mean postoperative UDVA was 0.16 logarithm of the minimum angle of resolution (logMAR) ± 0.18 (SD), and the mean postoperative CDVA was 0.01 ± 0.08 logMAR. The mean postoperative spherical equivalent was 0.04 ± 0.92 diopter (D). Twenty-five eyes (62.5%) were within ±0.50 D of emmetropia, and 35 eyes (87.5%) were within ±1.0 D of emmetropia. Nine eyes (22.5%) had a laser enhancement because of a residual refraction error. Eleven eyes (27.5%) had a neodymium:YAG laser capsulotomy because of PCO. CONCLUSIONS: In general, multifocal IOL implantation after corneal refractive laser surgery for hyperopia resulted in good visual acuity and refraction. The magnitude of previous hyperopia did not influence the refractive predictability.

RESUMO

PURPOSE: To report on the beneficial results of an intense regimen of 0.05% cyclosporine eye drops, eight times a day in patients with therapy resistant vernal shield ulcers. METHODS: Case cohort of four eyes of three male children with vernal keratoconjunctivitis complicated by shield ulcers, who were treated with frequent cyclosporine 0.05% eye drops and observed for up to 5 years. RESULTS: Quick resolution of the shield ulcers and complete re-epithelialization within 14-25 days was observed after adding intensive treatment with cyclosporine 0.05% to regular anti-inflammatory, histamine blocking, and surgical therapy. In one patient, additional scraping of the bottom of the ulcer was needed. CONCLUSIONS: In patients with vernal shield ulcers, frequent installation of low-concentration cyclosporine eye drops seems to have a promising therapeutical value.

RESUMO

PURPOSE: To report the results of long-term topical treatment with bevacizumab (Avastin) 5 mg/mL eyedrops in a case of aniridia-related neovacularization of the cornea. METHODS: Interventional case report. A female patient with aniridia had a decrease in the best corrected visual acuity from 0.32 to 0.02 in the OS over the course of 4 years, secondary to central corneal neovascularization and epithelial breakdown. Vision in the OD was 0.2. In 2008, at age 28, a shared decision was made to start off-label treatment with bevacizumab eyedrops 0.5% in both eyes. After 9 years, the visual acuity in the OD remained stable, with stability of the macropannus and maintenance of central corneal clarity. In the OS, the central corneal neovascularization regressed, the epithelium regained its clarity, and after cataract surgery visual acuity was regained to 0.32. RESULTS: After 9 years of treatment with topical bevacizumab, vision acuity is comparable to the situation of 12 years previously: Visual acuity remained stable in the ODS. CONCLUSION: In a young patient with progressive corneal neovascularization secondary to aniridia, stability of central corneal neovascularization was obtained and corneal clarity was preserved by adding a daily drop of bevacizumab 5 mg/mL. No adverse events occurred. Vessel growth was inhibited, and as such, the progression of the natural history of the patient's disease was halted. More clinical study with longer follow-up is needed to investigate the applicability of treatment with topical VEGF inhibitors in aniridia.

RESUMO

PURPOSE: To describe the refraction and visual acuity outcomes of multifocal intraocular lens (IOL) implantation in patients with previous corneal refractive laser surgery for myopia. SETTING: Academic Medical Center, University of Amsterdam, Amsterdam, and Retina Total Eye Care, Driebergen, the Netherlands. DESIGN: Retrospective cohort study. METHODS: The 3-month results after implantation of a multifocal IOL (Acrysof Restor) in patients who had corneal refractive laser surgery for myopia were analyzed. The primary outcome measures were corrected distance visual acuity, uncorrected distance visual acuity (UDVA), and refraction. The secondary outcome measures were number of laser enhancements, corneal irregularity, pre-laser magnitude of myopia, and posterior capsule opacification (PCO) rate. RESULTS: Seventy-seven eyes of 43 patients were included. Twenty-nine eyes had lens extraction because of cataract, and 48 eyes had a refractive lens exchange. The mean postoperative UDVA was 0.14 logarithm of minimum angle of resolution ± 0.22 (SD). The mean postoperative spherical equivalent was -0.38 ± 0.78 diopter (D). Fifty-seven percent of eyes were within ±0.50 D of emmetropia, and 86% were within ±1.0 D. Sixteen eyes (20.8%) had laser enhancement because of residual refraction. Fourteen eyes (18.2%) had a neodymium:YAG laser capsulotomy because of PCO. Eyes with pre-laser myopia greater than 6.0 D had a less predictable outcome than eyes with pre-laser myopia less than 6.0 D (P = .026). CONCLUSIONS: Multifocal IOL implantation after corneal refractive laser surgery for myopia resulted in good visual acuity and refraction. Results were less predictable with myopia greater than 6.0 D.

RESUMO

PURPOSE: To assess the change and interrelationship of the field of binocular single vision (BSV) and the quality of life (QoL), tested with two different tools, after one or two strabismus surgeries in patients with Graves' orbitopathy (GO). METHODS: Prospectively, consecutive patients with GO who were scheduled for their first strabismus surgery were recruited from five centres specialized in the treatment of GO. One week preoperatively and 3 months after the last operation, a full ophthalmic and orthoptic examination was performed. Change in field of BSV, GO-QoL and thyroid eye disease-QoL (TED-QoL) was recorded. RESULTS: A total of 59 met all the eligibility criteria of whom 15 underwent two strabismus operations. The median (interquartile range) preoperative score of the field of BSV was 0 (0-0), which improved to 73 (53-85) after the correction(s) (p < 0.001). After the first surgery, a significant higher score of the field of BSV was found in the patients who underwent one operation (76; 60-86) compared with those who underwent two 0 (0-63) operations (p < 0.001). After the second surgery, this score increased to 62 (40-76; p = 0.05). A moderate correlation was found between the score of the field of BSV and the GO-QoL visual functioning (VF) questionnaires (r = 0.485; p < 0.001). Both the GO-QoL and TED-QoL for VF and appearance (AP) showed significantly higher scores after the treatment (p < 0.001). CONCLUSION: After strabismus surgery in GO patients, both the field of BSV and quality of life questionnaires increase. In approximately 30% of the patients, an additional strabismus surgery is performed. This second surgery significantly expands the field of BSV and the quality of life.

RESUMO

BACKGROUND: Pre- or retroseptal bacterial orbital cellulitis (pOC/rOC) is not an uncommon orbital disease. Treatment consists of antibiotics with or without surgical drainage. Several questions regarding course, complications and outcome of treatment are unanswered and the indication for surgery is not well defined. The aim of this study is to: 1. describe the outcome of orbital cellulitis (OC) in a large cohort, 2. assess the significance of Chandler's classification, 3. assess the incidence of abscess formation in OC, and 4. redefine criteria for surgery. METHODS: Retrospective case series of patients with OC seen between 1-1-2007 and 1-1-2014 in a tertiary referral center. RESULTS: Sixty-eight patients presented with (presumed) bacterial pOC. Two out of these 68 developed rOC. All 68 patients had a full recovery. Forty-eight patients presented with rOC. Four out of 48 (8%) had intracranial extension of the infection at the time of admission. No admitted patient developed distant seeding. Only four (8%) patients with rOC had a true orbital abscess. In the other 92% we found a diffuse orbital inflammation or a subperiosteal empyema. Forty-four (92%) patients with rOC had a full recovery. CONCLUSIONS: 1. The prognosis of both pOC and rOC nowadays is generally favorable. 2. Chandler's classification is of little use. 3. True abscess formation in OC is rare. 4. The indication for surgical intervention must be based on the clinical presentation and the assessment of true orbital abscess formation.

RESUMO

PURPOSE: To evaluate the refractive accuracy of intraocular lens (IOL) power calculation after phacovitrectomy. SETTING: Eye Hospital Zonnestraal and Department of Ophthalmology Academic Medical Center, Amsterdam, the Netherlands. DESIGN: Retrospective comparative case series. METHODS: Refraction results 1 month after phacovitrectomy or phacoemulsification were compared with predicted refractions calculated using the IOLMaster 500 and the Haigis formula. Indications for vitrectomy were macular pucker, macular hole, vitreous floaters, vitreous hemorrhage, and vitreomacular traction. Enrolled eyes had an axial length (AL) between 20.13 mm and 29.43 mm. RESULTS: The phacovitrectomy group comprised 133 eyes (133 patients) and the phacoemulsification group, 132 eyes (132 patients). The refractive outcomes after phacovitrectomy (-0.06 diopter [D] ± 0.50 [SD]) and phacoemulsification (-0.08 ± 0.47 D) were comparable (P = .74). The final postoperative refraction was within ±1.00 D of the preoperative refractive target in 94.9% and 94.6% of phacovitrectomy cases and phacoemulsification cases, respectively. Subgroup analysis found no increased risk for refractive surprises after gas tamponade or in eyes with an AL of 26.00 mm or greater. CONCLUSIONS: Standard IOL power calculation used in regular phacoemulsification surgery was accurate in phacovitrectomy procedures in eyes with a wide range of AL and a wide range of vitrectomy indications. No tendency toward a myopic shift was found.

RESUMO

PURPOSE: To report the incidence of opacification of the intraocular lens (IOL) after Descemet stripping endothelial keratoplasty (DSEK) in an academic ophthalmology clinic. METHODS: In this retrospective case series, all patients who underwent DSEK between 2003 and 2013 were included. In 2008, the first patient presented with reduced vision as a result of opacification of the IOL in our clinic. The period between DSEK surgery and diagnosis of IOL opacification, Snellen corrected distance visual acuity before and after the appearance of IOL opacification, IOL specifications, and incidence of IOL exchange were assessed. RESULTS: A total of 160 eyes were operated on. Opacification was seen in 8 eyes (5%) and was diagnosed between 4 and 24 months after DSEK (mean, 9.6; SD, 6.3; range, 4-24 months). The mean Snellen corrected distance visual acuity was 0.6 (SD, 0.2; range, 0.2-0.8) before opacification and 0.3 (SD, 0.2; range, 0.02-0.6) after opacification of the IOL occurred. The IOL material was hydrophilic acrylic in all patients. In 4 eyes, IOL exchange was performed. CONCLUSIONS: Opacification of the IOL can be a vision-threatening late complication after DSEK and was seen in 8 of 160 eyes.

RESUMO

BACKGROUND: Metastasis of breast carcinoma to the orbit is characterized by symptoms of altered appearance and double vision. A combination of enophthalmos, ptosis and impairment of eye movements is typical. Sometimes these symptoms are the first manifestation of breast carcinoma. CASE DESCRIPTION: Two female patients, aged 66 and 52, presented with enophthalmos. Both had recently undergone mammography with no abnormalities being observed. CT scans of these patients disclosed an intra-orbital, space-occupying process. Histological examination of biopsies from the abnormal tissue revealed that both patients had metastatic breast carcinoma. CONCLUSION: In a female patient with non-traumatic enophthalmos, metastasis of breast carcinoma must be ruled out and reliance may not be placed on a mammogram revealing no abnormalities.
