ABSTRACT
BACKGROUND AND OBJECTIVE: To assess the surgical outcomes of the use of tissue glue to close sclerotomy sites when required and the views of ultrasound biomicroscopy of the sclerotomy sites in 23- and 25-gauge vitrectomy systems. PATIENTS AND METHODS: A 25-gauge transconjunctival sutureless vitrectomy was performed in 38 eyes and a 23-gauge transconjunctival sutureless vitrectomy was performed in 46 eyes for various vitreoretinal diseases. Wound leakage occurred at the sclerotomy sites at the end of the surgery in 6 eyes with 23-gauge transconjunctival sutureless vitrectomy and 7 eyes with 25-gauge transconjunctival sutureless vitrectomy. The sclerotomy sites were closed by using tissue glue to prevent wound leakage and evaluated with ultrasound biomicroscopy postoperatively. RESULTS: No wound leakage was observed at the end of the surgical procedure or during the follow-up period. Abnormal fibrous ingrowth was not detected at the sclerotomy sites by means of ultrasound biomicroscopy. CONCLUSION: The results demonstrated the efficacy of tissue glue for closing site ports when wound leakage is observed in transconjunctival sutureless vitreoretinal surgery.

PURPOSE: To report the ultrasound biomicroscopy (UBM) findings of anterior segment tumors and simulating conditions. METHODS: Thirty-five patients underwent UBM. Of those, 16 had histopathologically or cytopathologically diagnosed tumors, and 19 had clinically diagnosed lesions. RESULTS: The study material comprised 13 iris pigment epithelial (IPE) cysts, 7 ciliary body melanomas, 4 iris melanomas, 4 iris nevi, 3 intraocular invasions of conjunctival squamous cell carcinoma, 2 ring melanomas of the anterior chamber angle, 1 medulloepithelioma and 1 pars plana cyst. On UBM, all IPE cysts presented as cystic lesions with a thin cyst wall and no solid components. All ciliary body melanomas showed low to medium reflectivity, with cavitation in one case and extraocular extension in another. Iris melanomas presented as anterior (stromal) iris lesions with medium to high internal reflectivity. There was irregularity and convex bowing of the posterior iris plane in iris melanomas, a feature not seen in iris nevi. Intraocular invasion of conjunctival squamous cell carcinoma was evidenced as areas of medium to high reflectivity in the ciliary body and iris, loss of the acute angle shape and highly reflective spots in the anterior chamber. CONCLUSIONS: UBM was particularly useful in the diagnosis of IPE cysts, in the visualization of small ciliary body melanomas, in the differentiation of iris melanomas from iris nevi and in the demonstration of intraocular invasion from conjunctival squamous cell carcinoma.

PURPOSE: To evaluate the factors influencing AcrySof intraocular lens (IOL) (Alcon Laboratories) movement and near visual acuity after cyclopentolate 1% and pilocarpine 2%. SETTING: Department of Ophthalmology, University of Ankara, Ankara, Turkey. METHODS: Thirty eyes of 22 patients with AcrySof IOL implantation were included in this prospective study. Near visual acuity (Jaeger) at 35 cm through best distance correction without an add and pupil diameter were measured and correlated with anterior chamber depth (ACD) measured with ultrasound biomicroscopy (UBM) after application of cyclopentolate 1% and pilocarpine 2%, respectively. The magnitude of the change in the ACD was correlated with the accommodation amplitude, patient age, time interval between surgery and imaging, preoperative axial length, capsulorhexis diameter, ACD during cycloplegia, IOL diameter, and presence of posterior capsule opacification (PCO). RESULTS: Near visual acuity significantly decreased after application of cyclopentolate 1% and increased after application of pilocarpine 2% (P < .001) in all eyes. The IOL moved anteriorly in 8 (26%) eyes and posteriorly in 22 (74%) eyes after pilocarpine 2%. There was no correlation between the ACD and near visual acuity under cyclopentolate 1% (r = 0.06, P > .05) or pilocarpine 2% (r = 0.04, P > .05). There was a moderate correlation between the anterior IOL movement and accommodation amplitude (P < .05, r = 0.42). There was no correlation between the magnitude of the IOL movement and patient age, time interval between surgery and imaging, the preoperative axial length, capsulorhexis diameter, ACD during cycloplegia, IOL diameter, and the presence of PCO (P > .05). CONCLUSIONS: There was better near visual acuity in all eyes with the AcrySof MAIOL, although most IOLs move slightly backward after of pilocarpine 2%. This points out pseudoaccommodation rather than pseudophakic accommodation. Ultrasound biomicroscopy is useful in determining the ACD and the relation between the IOL and the surrounding tissues after cataract surgery.

BACKGROUND AND OBJECTIVE: To evaluate lacrimal drainage in patients who have undergone successful dacryocystorhinostomy using quantitative dacryoscintigraphy. PATIENTS AND METHODS: This study included 72 eyes of 72 patients. There were 26 males and 46 females, with a mean age of 39.6 years (range, 8 to 67 years). The patients were subdivided into three groups. Group 1 consisted of 35 eyes with external dacryocystorhinostomy, group 2 consisted of 15 eyes with endoscopic dacryocystorhinostomy, and group 3 consisted of 22 eyes with conjunctival dacryocystorhinostomy with a Jones tube. There was no epiphora in patients and the lacrimal drainage systems were patent by irrigation. The other normal eyes of the patients were evaluated as controls. RESULTS: In groups 1 and 2, the mean T(1/2) values for the palpebral aperture were lower than those for normal eyes, and this difference was statistically significant (P < .01). In group 3, no significant difference was detected in the mean T(1/2) values for the palpebral aperture. CONCLUSIONS: Tear flow was slower in patients who had had external and endoscopic dacryocystorhinostomy, but conjunctival dacryocystorhinostomy did not affect T(1/2) values for the palpebral aperture.

Absence or deficiency of tear volume (alacrima) is rarely seen in pediatric ophthalmology. It is often a part of the multiple systemic anomalies like Riley-Day syndrome and anhidrotic ectodermal dysplasia, or it may be associated with adrenal gland insufficiency, achalasia, and neurologic disorders like Allgrove's syndrome. We report on a 7-year-old girl presenting alacrima, achalasia, and mental retardation with normal adrenocortical function.

We report a case of unilateral congenital ptosis which is associated with ocular and systemic congenital malformations including mild microphthalmia, microcornea, cataract, iris and chorioretinal coloboma, ectopic kidney, and ventricular septal defect. An inciting factor, acting during the second month of gestation, may affect the development of the eye, heart, and abdomen and may lead to congenital malformations. Although congenital ptosis rarely presents with ocular and systemic congenital malformations, ophthalmologists should be alert for the possibility of coexisting structural defects. Congenital ptosis is a muscular dystrophy demonstrated by various degrees of muscular degeneration and it may rarely be associated with ocular and systemic congenital malformation. Here, we report a case of congenital ptosis associated with more than one ocular and systemic malformation.

PURPOSE: To compare the clinical findings and the cytological grade of the disease before and after 6 months of topical cyclosporine A treatment in patients with dry eye. SETTING: : This single-center prospective study was performed at the Department of Ophthalmology, Ankara University School of Medicine, between January 2007 and June 2008. METHOD: Forty-five patients with dry eye (with 5 mm/5 minutes or less Schirmer test) were included in the study. Patients were treated with cyclosporine A 0.005% ophthalmic emulsion (RESTASIS) twice daily in addition to lubricant eyedrops 5 times a day. Schirmer test values, tear breakup time (BUT), and impression cytology (goblet cell density, nucleus to cytoplasmic ratio, and epithelial cell morphology) were evaluated at baseline and after 6 months. RESULTS: Before and after 6 months of the treatment with topical cyclosporine A, the median Schirmer test scores were found as 3.00 and 4.00 mm, respectively. The median BUT score at baseline was 4.00 seconds, and after treatment, the median score was 5.00 seconds. There were statistically significant differences in the median Schirmer and BUT values between, before, and after 6 months of treatment (P < 0.05). The mean cytological grade according to Nelson grading system was 1.84 at baseline and 1.51 after treatment with topical cyclosporine A for 6 months. Statistically significant improvement in cytological grades after treatment was observed (P < 0.05). CONCLUSION: Treatment of patients with dry eye for 6 months with topical cyclosporine A resulted in an increase in Schirmer test results, an increase in BUT scores, and an improvement in cytological grade of the disease.

PURPOSE: To evaluate the efficacy of the transillumination technique for precisely locating the ciliary sulcus in transscleral fixation of posterior chamber intraocular lenses (PC IOLs) by determining the haptic positions with ultrasound biomicroscopy (UBM). SETTING: Department of Ophthalmology, Numune Training and Research Hospital, Ankara, Turkey. METHODS: Ultrasound biomicroscopy was used to determine the haptic positions in eyes with ab externo transsclerally fixated PC IOLs. Eyes were randomly assigned to a control group, in which transscleral fixation of a PC IOL was performed, or an endoilluminator-assisted group, in which transscleral fixation was combined with transillumination. RESULTS: The study evaluated 33 eyes of 28 patients ranging in age from 16 to 81 years. The control group comprised 19 eyes (17 patients) and the endoilluminator-assisted group, 14 eyes (12 patients). All haptics were easily visualized with UBM. The UBM examination showed that the rate of haptics located in the sulcus was statistically significantly higher in the endoilluminator-assisted group (64%) than in the control group (24%) (P= .001). There was no significant difference in either group in the rate of precise sulcus location between the straight needle and the 28-gauge insulin needle (P> .05). CONCLUSIONS: Ultrasound biomicroscopy showed the difficulty in reliably suturing the haptics in the ciliary sulcus, even with the use of a transillumination technique. However, the results suggest that the transillumination technique is a safe and easy procedure and helps the surgeon identify the ciliary sulcus during transscleral fixation of PC IOLs more precisely than without the use of transillumination.

PURPOSE: To evaluate the results of lacrimal probing in children at or older than 1 year of age with congenital nasolacrimal duct obstruction. MATERIALS AND METHODS: Fifty eyes of 38 children (24 males, 14 females) with congenital epiphora who underwent nasolacrimal duct probing were evaluated in a prospective study. The age of the patients was between 12 and 101 months (mean: 33 months). Success of probing was defined as complete resolution of preoperative symptoms and signs. The mean follow-up was 8 months (3-28 months). RESULTS: The success rate of probing was 88% (44/50 eyes). Residual epiphora was observed in 6 eyes of 4 patients (12%). Age of the patient, gender, the frequency of epiphora before probing and the unilaterality or bilaterality of epiphora did not correlate with the success of probing (p > 0.05). CONCLUSION: Nasolacrimal duct probing is advocated as a primary treatment in children younger than 9 years of age before proceeding to more complex treatment options. Unsuccessful probing may result from the selection of nonmembranous obstructions rather than the increased age of the patients.

We analyzed ocular and ultrasonographic findings of microphthalmos and associated ocular and systemic pathologies in 27 microphthalmic eyes. A high incidence of consanguinous marriages (26%) was present among the parents of patients. Associated systemic abnormalities were growth retardation, congenital rubella, cleft lip and palate, facial hemangioma, inguinal hernia, clinodactyly, Hurler syndrome, Goltz-Gorlin syndrome and Hallermann-Streiff syndrome. A variety of ocular/systemic abnormalities were encountered. Early ultrasonographic diagnosis and description of other ocular and systemic pathologies are essential.

The aim of this study was to determine the diagnostic accuracy of gadolinium-enhanced three-dimensional (3D) fast spoiled gradient-recalled (FSPGR) MR dacryocystography in patients with epiphora. Bilateral nasolacrimal systems of 19 patients suspected of having nasolacrimal canal obstruction were evaluated with MR dacryocystography. A sterile 0.9% NaCl solution containing 1:100 diluted gadolinium chelate was instilled into the bilateral conjunctival sacs of the patients. The 3D FSPGR sequence was used with 1.0-T scanner with the following parameters: TR 9.3 ms; TE 2 ms; flip angle 20; 256x224 matrix; 13- or 26-cm field of view; and 1-mm slice thickness. Seventeen patients had digital dacryocystography for comparison which we considered standard of reference. Thirty-four nasolacrimal systems were evaluated with MR and digital dacryocystography. Discrepancies between the findings of both methods were detected in 2 patients. The overall sensitivity of MR in detecting the obstruction was 100%. Magnetic resonance helped to determine the canalicular and ductal obstruction in 100% of the patients and the saccular obstruction in 80% of the patients. We conclude that 3D FSGR technique for MR dacryocystography is a reliable and noninvasive method in the evaluation of the obstruction level in the lacrimal system in patients with epiphora.

Endoscopic dacryocystorhinostomy (EN-DCR) is a procedure that presents itself as an alternative choice to the conventional external approach. This study describes the results of endoscopic endonasal non-laser lacrimal surgery. We reported the data of 64 procedures of 63 patients with epiphora or chronic dacryocystitis who underwent primary EN-DCR by means of a microdrill or revision EN-DCR. One of these cases had bilateral surgery. There were 42 women and 21 men. Thirty-four cases had primary EN-DCR and 30 cases had revision EN-DCR secondary to previously failed external DCR. Mean follow up time was 11.34 months. The procedure was successful in 79.4% of primary EN-DCR cases and in 80% of revision EN-DCR cases. The overall success rate was 79.6%. Postoperative complications included periorbital edema, eyelid ecchymosis, punctal granuloma, cyst of the punctum, adhesion between the superior and inferior punctum. Tube dislocation occurred in 3 patients. Premature loss of silicone tube was determined in 5 patients and granulation tissue occurred at the internal osteum in 11 cases. EN-DCR, when compared with external dacryocystorhinostomy (EX-DCR), has lower success rate, but provides the potential advantages of better intraoperative hemostasis, and lack of cutaneous scar.

PURPOSE: To evaluate and measure the thickness of the levator aponeurosis by ultrasound biomicroscopy in congenital dysmyogenic and aponeurotic blepharoptosis. METHODS: Forty-four upper eyelids of 22 patients who had unilateral blepharoptosis were evaluated by ultrasound biomicroscopy. The patients ranged in age from 13 to 69 years (mean, 35.4 +/- 20.2 years). Fourteen patients were male and 8 patients were female. Seven patients had congenital dysmyogenic blepharoptosis and 15 patients had aponeurotic blepharoptosis. Imaging was performed with a 50-MHz transducer. The thickness of the levator aponeurosis was measured centrally at the upper border of the tarsus. RESULTS: The levator aponeurosis was imaged in all eyelids except for one eyelid with aponeurotic blepharoptosis. The mean thickness of the levator aponeurosis was 0.39 +/- 0.10 mm in the ptotic eyelid and 0.42 +/- 0.09 mm in the control eyelid of the patients with congenital dysmyogenic blepharoptosis (p = 0.043). The mean thickness of the levator aponeurosis was 0.26 +/- 0.05 mm in the ptotic eyelid and 0.36 +/- 0.04 mm in the control eyelid of the patients with aponeurotic blepharoptosis (p = 0.001). The thickness of the levator aponeurosis was correlated with the palpebral fissure height (p = 0.013, r = 0.644) in aponeurotic blepharoptosis. The thickness of the levator aponeurosis was correlated with the levator function (p = 0.033, r = 0.795) in congenital dysmyogenic blepharoptosis. CONCLUSIONS: The thickness of the levator aponeurosis can be measured with ultrasound biomicroscopy. The most common pathology in aponeurotic blepharoptosis is thinned-out aponeurosis. The levator aponeurosis of the ptotic eyelid is thinner than the normal eyelid in congenital ptosis.
