Graded full-thickness anterior blepharotomy for correction of upper eyelid retraction not associated with thyroid eye disease

PURPOSE: To evaluate the efficacy of graded full-thickness anterior blepharotomy for upper eyelid retraction of various causes not associated with Graves eye disease. METHODS: Twenty-one eyelids of 18 patients with upper eyelid retraction not caused by Graves eye disease were treated with graded full-thickness anterior blepharotomy. Preoperative and postoperative symptoms, midpupil to upper eyelid distance, lagophthalmos, and superficial punctuate keratopathy were evaluated. RESULTS: Upper eyelid retraction was due to facial nerve palsy in 4 patients (22%), overcorrected ptosis in 5 patients (28%), and cicatrix after trauma in 6 patients (33%). One patient each (6% each) had retraction from graft-versus-host disease, after blepharoplasty, and after orbicularis oculi myectomy for blepharospasm. At a mean of 10 months follow-up, presenting symptoms resolved or improved in 17 patients (94%) and remained unchanged in 1 patient (6%). Midpupil to upper eyelid distance, lagophthalmos, and superficial punctuate keratopathy all improved significantly (all p < 0.001). No surgical complications occurred. CONCLUSIONS: Graded full-thickness anterior blepharotomy is a safe, effective, and rapid technique for patients with symptomatic upper eyelid retraction due to etiologies other than Graves eye disease. This technique improves symptoms and signs of ocular exposure while addressing relative upper eyelid height symmetry and contour.     

Interaction with intraocular lens materials: Does heavy silicone oil act like silicone oil?

PURPOSE: To determine the interaction of heavy silicone oil with various intraocular lens (IOL) materials and whether heavy silicone oil covers the silicone IOL optic as silicone oil does. SETTING: Department of Ophthalmology, Dokuz Eylul University, Izmir, Turkey. METHODS: The study group comprised 5 poly(methyl methacrylate) (PMMA) IOLs, 4 foldable silicone IOLs, 5 foldable hydrophilic acrylic IOLs, and 5 foldable hydrophobic acrylic IOLs. Each IOL was bathed in balanced salt solution (BSS) for 10 minutes and then placed in heavy silicone oil dyed with Sudan Black for another 10 minutes. Afterward, each IOL was reimmersed in BSS for 5 minutes and examined under the light microscope. Digital images were analyzed to determine the optic area covered with heavy silicone oil. RESULTS: The mean heavy silicone oil coverage was 7.05% +/- 7.88% (SD) (range 1.13% to 20.54%) on PMMA IOLs, 100% on silicone IOLs, 12.17% +/- 11.43% (range 1.25% to 31.52%) on hydrophobic acrylic IOLs, and 34.64% +/- 13.28% (range 12.57% to 44.42%) on hydrophilic acrylic IOLs. Heavy silicone oil coverage of silicone IOLs was statistically significantly greater than the coverage of other IOL materials. CONCLUSION: Heavy silicone oil acted the same as silicone oil and covered the entire surface of silicone IOLs.     

Functional outcomes after implantation of Tecnis ZM900 and Array SA40 multifocal intraocular lenses

PURPOSE: To evaluate the functional outcome after implantation of the Tecnis ZM900 multifocal intraocular lens (IOL) (AMO) and the Array SA40 multifocal IOL (AMO). SETTING: Department of Ophthalmology, Bundesknappschaft s Hospital, Sulzbach, and the Department of Ophthalmology, Marienhospital, Aachen, Germany. METHODS: In a prospective comparative 2-center trial, Tecnis ZM900 and the Array SA40 multifocal IOLs were bilaterally implanted in 50 patients (50 eyes Tecnis, 50 eyes Array) by 1 surgeon at each center. The following parameters were assessed 30 to 60 days and 120 to 180 days after surgery in both eyes: refraction, pupil size, uncorrected and best corrected visual acuities for distance and near at different contrast levels, and photopic and mesopic contrast sensitivity at different spatial frequencies. Patient satisfaction (spectacle independence, photic phenomena, overall satisfaction) was assessed by a questionnaire. RESULTS: The main differences between the 2 multifocal IOLs were the better uncorrected near visual acuity (P<.001), distance-corrected near visual acuity (P<.001), the mesopic contrast sensitivity at high spatial frequencies (P<.05) as well as greater independence from spectacles in patients with the Tecnis multifocal IOL, resulting in higher levels of patient satisfaction. CONCLUSION: The aspherical diffractive Tecnis multifocal IOL gave better outcomes than the Array multifocal IOL.     

A multicenter experience of thrombotic microangiopathies in Turkey: The Turkish Hematology Research and Education Group (ThREG)-TMA01 study

Thrombotic microangiopathies (TMAs) are rare, but life-threatening disorders characterized by microangiopathic hemolytic anemia and thrombocytopenia (MAHAT) associated with multiorgan dysfunction as a result of microvascular thrombosis and tissue ischemia. The differentiation of the etiology is of utmost importance as the pathophysiological basis will dictate the choice of appropriate treatment.We retrospectively evaluated 154 (99 females and 55 males) patients who received therapeutic plasma exchange (TPE) due to a presumptive diagnosis of TMA, who had serum ADAMTS13 activity/anti-ADAMTS13 antibody analysis at the time of hospital admission. The median age of the study cohort was 36 (14-84). 67 (43.5%), 32 (20.8%), 27 (17.5%) and 28 (18.2%) patients were diagnosed as thrombotic thrombocytopenic purpura (TTP), infection/complement-associated hemolytic uremic syndrome (IA/CA-HUS), secondary TMA and TMA-not otherwise specified (TMA-NOS), respectively. Patients received a median of 18 (1­75) plasma volume exchanges for 14 (153) days. 81 (52.6%) patients received concomitant steroid therapy with TPE. Treatment responses could be evaluated in 137 patients. 90 patients (65.7%) achieved clinical remission following TPE, while 47 (34.3%) patients had non-responsive disease. 25 (18.2%) non-responsive patients died during follow-up. Our study present real-life data on the distribution and follow-up of patients with TMAs who were referred to therapeutic apheresis centers for the application of TPE.     

The spectrum of diseases causing fever of unknown origin in Turkey: a multicenter study.

OBJECTIVE: The purpose of this trial was to determine the spectrum of diseases with fever of unknown origin (FUO) in Turkey. METHODS: A prospective multicenter study of 154 patients with FUO in twelve Turkish tertiary-care hospitals was conducted. RESULTS: The mean age of the patients was 42+/-17 years (range 17-75). Fifty-three (34.4%) had infectious diseases (ID), 47 (30.5%) had non-infectious inflammatory diseases (NIID), 22 (14.3%) had malignant diseases (MD), and eight (5.2%) had miscellaneous diseases (Mi). In 24 (15.6%) of the cases, the reason for high fever could not be determined despite intensive efforts. The most common ID etiologies were tuberculosis (13.6%) and cytomegalovirus (CMV) infection (3.2%). Adult Still's disease was the most common NIID (13.6%) and hematological malignancy was the most common MD (7.8%). In patients with NIID, the mean duration of reaching a definite diagnosis (37+/-23 days) was significantly longer compared to the patients with ID (25+/-12 days) (p=0.007). In patients with MD, the mean duration of fever (51+/-35 days) was longer compared to patients with ID (37+/-38 days) (p=0.052). CONCLUSIONS: Although infection remains the most common cause of FUO, with the highest percentage for tuberculosis, non-infectious etiologies seem to have increased when compared with previous studies.
