Levator palpebralis superioris histopathologic findings in congenital ptosis and surgical outcome after its resection: Is there any association?

PURPOSE: To evaluate the histopathologic findings of Levator palpebralis superioris (LPS) muscle biopsy after LPS resection for treatment of congenital ptosis and its possible relation with surgical outcomes.Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name). Author 4 Given name: [Seyed Mohsen] Last name [Rafizadeh]. Author 6 Given name: [Seyed Ali] Last name [Sonbolestan].Also, kindly confirm the details in the metadata are correct.The author names and the sequence are correct. METHODS: Congenital ptosis patients were enrolled in this retrospective study. All of them underwent full ophthalmologic examination included of Margin-reflex distance 1 (MRD-1) and LPS function measurement preoperatively. The patients were followed for 3 months for the postoperative period and after that the measurements were repeated. Histologic parameters including percentages of fat, striated and smooth muscle, and fibrous tissue. The histopathologic findings and their possible correlation with the measurements are analyzed. RESULTS: Sixty-seven patients with unilateral congenital ptosis were enrolled. 45 patients (67.2%) were males. The mean age of patients was 16.10 ± 11.18 years. The patients' MRD-1 was improved significantly from 0.82 ± 1.26 mm to 3.85 ± 1.25 mm after LPS resection (P = 0.000). The success rate was 80.3%. There were no correlations between MRD change and histopathologic tissue percentages but significant correlation was found between success of surgery and fibrous tissue percentage of resected sample (P = 0.033). CONCLUSIONS: The histopathology of the LPS may be useful in prediction of surgical outcome after LPS resection in congenital ptosis patients. The percentage of fibrous tissue play an important role.

The role of Whitnall's ligament position in the success of levator resection surgery in congenital ptosis.

PURPOSE: This study aimed to investigate the role of Whitnall's ligament position in the success of levator resection surgery in congenital ptosis. METHODS: It was an interventional case series on patients with congenital ptosis who underwent levator muscle resection in Farabi Eye Hospital (2020-2022). Patients with incomplete follow-up, a history of trauma, poor Bell's phenomenon, previous ocular and lid surgeries, poor levator function (≤ 4mm), and syndromic ptosis or systemic diseases were excluded. During the surgery, several factors, including the distance between Whitnall's ligament and the upper edge of the tarsus (W-distance), the vertical length of the tarsus (T-length), and the amount of levator muscle resection (LMR), were measured. A successful outcome was defined as the inter-eye difference of margin reflex distance-1 (MRD1) ≤ 1 and post-op MRD1 ≥ 3 OR the inter-eye difference of MRD1 ≤ 0.5 with any value of post-op MRD1 in unilateral cases and Postop-MRD1 > 3 in bilateral cases during the 3-months period. RESULTS: Thirty four eyes of 34 patients were included, and 79.4% of patients achieved successful outcomes. In univariate analysis, Preop-MRD1 and Preop-LF had meaningful negative correlations with the amount of LMR to reach the successful outcome (p < 0.05), which was only meaningful for Preop-LF in multivariable analysis (p < 0.05). Noticeably, W-distance had a significant positive correlation in univariate and multivariable linear regression (p < 0.05). CONCLUSIONS: W-distance can be considered a significant new parameter other than Preop-LF influencing the amount of levator resection needed to achieve success in levator resection surgery.

Association between blepharophimosis-ptosis-epicanthus inversus syndrome and lacrimal system anomalies.

Blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) is a congenital eyelid syndrome. Several associations, including the horizontal displacement of the puncta, canalicular stenosis, and ectropion have been so far described. Herein, we report a one-year-old boy presented to the Oculoplastic Clinic of Farabi Eye Hospital with complaint of watery discharge from both eyes since his birth. Based on the general appearance, the diagnosis of BPES was made. Mild tear regurgitation from the inferior punctum was noted. Detailed examination showed bilateral superior punctal agenesis with coloboma of both upper eyelids and lateral displacement of the inferior puncta. Multiple unsuccessful attempts of probing were suggestive of the presence of NLDO. The patient was managed by performing canaliculodacryocystorhinostomy. Osteotomy was performed to pass the canalicular and nasolacrimal obstruction followed by a successful canaliculoplasty. Finally, the lacrimal drainage system was intubated with a mono-Crawford from the inferior punctum into the nasal cavity. On the 1st-month follow-up visit, the complaint of watery discharge was resolved. This is an extremely rare report of nasolacrimal duct and sac anomaly in a patient with blepharophimosis. Thus, we recommend the evaluation of the nasolacrimal drainage system in these patients after the first month of birth.

COVID-19 associated rhino-orbito-cerebral mucormycosis, risk factors and outcome predictors; a multicentric study.

BACKGROUND: Since the onset of the Covid-19 pandemic, an increase in mucormycosis cases has been observed in many countries, including Iran. However, the role of covid-19 and associated risk factors have not been thoroughly investigated. OBJECTIVE: This study is designed to identify epidemiologic characteristics, risk factors, and outcome predictors of Covid-19-Associated Rhino-Orbito-Cerebral Mucormycosis (C-ROCM). METHODS: Data of pathology proven Covid Associated ROCM cases were retrospectively obtained from 7 tertiary care centers throughout Iran from February 20, 2021, to July 22, 2021. Univariate and multivariate analyses were performed using binary logistic regression to assess the effects of various factors on the outcome. RESULTS: A total of 132 patients with C-ROCM were included in the study. The mean age of patients was 61.6 ± 13.9 (60.6% male). In 12 patients (9.1%), both eyes were involved. Diabetes was the most common comorbidity (94.7%). The mortality rate was 9.1%, higher in males (12.5%) than females (3.8%). Severe vision impairment was seen in 58 patients (43.9%). Main factors that had a negative impact on the outcome in the univariate analysis include older age (P < 0.001), higher steroid dosage (P < 0.001), higher HbA1c level (P < 0.001), Covid-19 severity (P < 0.001), and brain involvement (P < 0.001). However, in the multivariate analysis, the effects of age (P = 0.062), steroid dosage (P = 0.226), and Covid-19 intensity (P = 0.084) decreased, and the difference was no longer statistically significant. CRAO was a predictor of mortality in the univariate analysis (P = 0.008, OR = 4.50), but in the multivariate analysis, this effect decreased and was no longer significant (P = 0.125). CONCLUSION: The risk of C-ROCM and its complications may increase in patients with more severe Covid-19, steroid over-prescription, ICU admission due to Covid-19, and poor glycemic control during and after Covid-19 treatment.

Post periorbital carboxytherapy orbital emphysema: a case report.

Periorbital carboxytherapy is used as one of the non-surgical facial rejuvenation methods in recent years. In this modality, the sterile carbon dioxide is injected into the subcutaneous space, assuming that to improve blood supply and repair of the injection site. Here, we report a 24- year-old woman who presented with acute bilateral orbital emphysema starting one day after cosmetic periorbital carboxytherapy. On physical examination, bilateral non-tender, non-erythematous swelling of both upper and lower lids was noted with crepitus on palpation. Uncorrected visual acuity (UCVA) of the patient in both eyes was 10/10 and RAPD was negative. The orbital computed tomography (CT) scan of the patient confirmed bilateral preseptal emphysema extending into orbital space through the orbital septum. Oral prednisolone 50 mg per day was prescribed, and the patient was observed closely. Gradually, periorbital pain and swelling subsided, and the symptoms resolved within one week.

Lacrimal Drainage System Problems After Rhinoplasty.

BACKGROUND: To report case series of permanent nasolacrimal system problems following rhinoplasty METHODS: The documents of patients with epiphora and history of rhinoplastic surgery were reviewed. The data of patients with permanent epiphora (continued over 3 months or started after 3 months of post-rhinoplasty surgery) and lacrimal drainage system (LDS) problems were analyzed for demographics, the result of diagnostic probing and irrigation, findings of orbital and paranasal sinuses CT scan, abnormalities in nasal endoscopy, treatment, and follow-up data. RESULTS: Forty-three patients with epiphora and history of rhinoplasty were referred to our clinic. Ten of them had permanent epiphora and LDS problems. In these patients, the mean time between rhinoplasty and initial symptoms of LDS problems was 10.3 ± 15.1 (range, 0-45 months) and the mean time between rhinoplasty and the LDS surgery was 22.2 ± 19.5 months (range 4-60 months). Diagnostic probing and irrigation test revealed canalicular stenosis in four (40%) patients, pus reflux in four (40%), clear reflux without passage in four (40%), and partial nasolacrimal duct obstruction (NLDO) in two (20%) of patients. DCR was performed in eight (80%) patients. Therapeutic probing and lacrimal intubation were performed in two (20%) patients. CONCLUSION: A permanent injury of the LDS is one of the important complications of the rhinoplastic surgery that should be managed based on the onset and duration of the symptoms and the location of the injury.

Solitary neurofibroma of the orbit with intracerebral extension associated with ocular surface melanocytoma: a case report.

Solitary or isolated neurofibroma is uncommonly observed in the orbit. Neurofibromas typically involve peripheral nerves and occasionally the cranial nerves. A 29-year-old man presented with recent onset left eye proptosis and exotropia. Physical examination was positive for hyperpigmented lesions of the ipsilateral ocular surface and hard palate. Imaging revealed an infiltrative orbital mass with extension through superior orbital fissure into the brain. There was also bone defect of greater sphenoid wing. Medial orbitotomy was performed to obtain biopsies of the orbital mass and the pigmented ocular surface lesions. Histopathologic diagnosis of neurofibroma was confirmed for the former and melanocytoma for the latter. His symptoms and examinations remained stable during the follow up. This case is unique due to several features, including extensive intracerebral spread of orbital neurofibroma in a patient without definite diagnosis of neurofibromatosis type 1 and association with ipsilateral ocular surface melanocytoma and palatal pigmented lesions. ABBREVIATIONS: CT: computed tomography; GFAP: glial fibrillary acid protein; MRI: magnetic resonance imaging; NF-1: neurofibromatosis type 1.

Clinical and Ultrasonographic Evaluation of Infantile Periocular Hemangioma Treated With Oral Propranolol.

PURPOSE: To evaluate the clinical and ultrasonographic response of periocular infantile capillary hemangioma during treatment with oral propranolol. METHODS: Patients with infantile periocular hemangioma and visual or cosmetic concerns were enrolled in this prospective interventional case series. Propranolol was given at a dose of 2 mg/kg per day for at least 6 months. Evaluation of treatment response was performed at month 3 (time point 1) and month 6 (time point 2). Gray scale ultrasonography and color Doppler imaging were performed at baseline and month 3. RESULTS: Thirty-one patients with mean age of 4.1 ± 2.3 months were eligible for analysis. Complete or near complete clinical resolution was observed in 4 patients (12.9%) at time point 1 and 21 patients (67.7%) at time point 2. Longitudinal diameter, transverse diameter, thickness, arterial peak systolic velocity, and end diastolic velocity reduced significantly from baseline to 3-month follow up. Complete clinical response at time point 2 was significantly higher in patients with peak systolic velocity reduction >50% from baseline to month 3 than patients with peak systolic velocity reduction of 10% to 50% and <10%. CONCLUSIONS: Propranolol is safe and effective for infantile periocular hemangioma. Ultrasonography and color Doppler imaging are useful modalities to monitor and predict the treatment response.

Color Doppler imaging of orbital vasculature before and after orbital decompression in thyroid eye disease.

Purpose: To measure alterations in orbital blood flow parameters using color Doppler imaging (CDI) before and after orbital decompression in patients with moderate to severe thyroid eye disease (TED). Methods: Resistance index (RI) and maximum and minimum velocity of ophthalmic artery (OA), superior ophthalmic vein (SOV), and central retinal artery (CRA) of 24 eyes (14 patients) with TED were measured before and at least 3 months after cosmetic orbital decompression procedure (single or double walls) using CDI. Complete eye examination was performed to define the severity (EUGOGO classification) and activity (clinical activity score) of TED. Results: Median OA (p = 0.003) and CRA (p = 0.001) resistance indices were significantly reduced postoperatively. Significant differences were found in maximum (p = 0.001) and minimum (p = 0.014) velocity of SOV before and after surgery. While a significant decrease in exophthalmometry was observed after the orbital decompression (p = 0.031), intraocular pressure changes were not significant (p = 0.182). Conclusion: Orbital decompression procedure led to a significant reduction of RI in both CRA and OA in patients with TED.

Color Doppler imaging in thyroid eye disease and its correlation to disease activity.

Purpose: To evaluate alterations in orbital color Doppler imaging (CDI) parameters and their correlation to disease activity and severity in patients with thyroid eye disease (TED). Methods: Seventy-six orbits of 45 TED patients and 40 orbits of 40 normal controls were enrolled in this cross-sectional study. According to clinical activity score (CAS), patients were categorized to active (CAS ≥ 3) or inactive disease (CAS < 3). Patients were also classified as having mild, moderate or severe disease. Peak systolic velocity (PSV), end diastolic velocity (EDV), and resistance index (RI) in ophthalmic artery and central retinal artery, and maximum and minimum velocity in superior ophthalmic vein and central retinal vein were determined in all subjects. Results: There was a significant difference in maximum velocity of superior ophthalmic vein and EDV and RI of ophthalmic artery between patients with TED and normal subjects. Superior ophthalmic vein maximum and minimum velocity and ophthalmic artery RI were significantly higher in patients with active disease than inactive cases. Disease severity did not affect the blood flow parameters independently. A cutoff point of 3.99 cm/s in superior ophthalmic vein maximum velocity yielded a sensitivity of 91.2% and specificity of 81.2% in detecting active disease. Conclusion: Retrobulbar blood flow is altered in TED and is related to disease activity. Superior ophthalmic vein maximum velocity could be helpful in differentiation of active and inactive cases.

Comparison of the success rate between monocanalicular and bicanalicular intubations in incomplete complex congenital nasolacrimal duct obstruction.

This article compares the success rate between monocanalicular (MCI) and bicanalicular intubations (BCI) in incomplete complex congenital nasolacrimal duct obstruction (CNLDO) and evaluate the factors responsible for the success of intubation. First, 99 patients with incomplete complex CNLDO underwent MCI (Monoka) or BCI (Crawford). Therapeutic success was defined as dye disappearance test grade 0-1 and complete resolution of previous symptoms at 12 months' follow-up. The success rates were compared between two groups. In all cases, the correlation of the age, gender, history of probing, and the presence of purulent discharges with the improvement in CNLDO symptoms were evaluated. 52 cases in the MCI and 47 cases in the BCI group were included. Then, 48 patients (48.5%) had history of probing. 26 patients (26.3%) had purulent discharges. The patients in the MCI group had lower success rate (59.6%) than the patients in the BCI group (74.4%) but the difference was not significant (p = 0.11). No complication occurred in the BCI group. In 4 cases (7.6%) in the MCI group, the tubes were lost before time of planned removal. In all cases, only preoperative absence of the pus was significantly correlated with success (p = 0.09 and OR = 0.39). BCI may be a better treatment for the patients with incomplete complex CNLDO. In silicone intubation for these cases, preoperative absence of purulent discharges could increase the success rate.

Fluorescein Dye Disappearance Test: A Reliable Test in Assessment of Success After Dacryocystorhinostomy Procedure.

PURPOSE: To evaluate the reliability indices of 5-minute fluorescein dye disappearance test (FDDT) for anatomical and subjective successes after dacryocystorhinostomy (DCR) procedure and to propose a paradigm in assessment of patients with tearing after DCR. METHODS: In a retrospective study, results of FDDT (176 eyes of 176 patients) were tested against the success rates after both external (135 eyes) and endoscopic endonasal (41 eyes) DCR and bicanalicular silicone intubation. Subjective success was defined as no symptom or intermittent excess tear (without overflow) in cold weather and anatomical success as free passage on irrigation test. Irrigation was performed at the time of tube removal in 58 eyes and at the last follow up in 118 eyes. Fluorescein dye disappearance test and subjective success were assessed either 1 week after tube removal (58 eyes) or at the last follow up (118 eyes). Grades 0 and 1 were considered as negative FDDT, and grades 2 and 3 as positive FDDT. RESULTS: Included patients who had primary acquired (94.9%) and traumatic (5.1%) nasolacrimal duct obstruction had a mean age of 49.8 years and a mean follow up of 11.7 months. There were 15 cases with previously failed DCR. The mean time of tube removal was 7.2 weeks (SD = 2.2). Final anatomical and subjective success rates were 95.5% (168/176) and 92% (162/176), respectively. Fluorescein dye disappearance test showed a sensitivity of 100% and a specificity of 86.3% for the anatomical success. They were 85.7% and 88.2% for the subjective success, accordingly. CONCLUSIONS: All anatomically failed DCR showed a positive FDDT (100% sensitivity) in this series. The proposed paradigm offers a less invasive approach to post-DCR epiphora.

Minimum incision no skin suture external dacryocystorhinostomy.

PURPOSE: To report the technique and results of 5-mm incision no skin suture external dacryocystorhinostomy procedure (Ext-DCR). METHODS: In a retrospective interventional case series, 77 patients (85 procedures) with nasolacrimal duct obstruction (NLDO) were included. The size of skin incision was 5 mm. Silicone tube was inserted in all and planned to be removed 6 weeks after the operation. Functional success was defined as no symptom or just excess tear in the cold weather and anatomical success as free irrigation at last follow-up time (at least 6 months) when patients' satisfaction (visual analogue score) on the site of incision was also recorded. RESULTS: There were 85 procedures in 77 patients (52 women; 67.5%) with primary acquired (82) or traumatic (3) NLDO and with a mean age of 52.9 years and follow up of 12.9 months. Associated common canalicular stenosis (membrane) was found in 15 (17.6%), canalicular stenosis in 2 (2.4%), and both in 2 (2.4%) cases. Anatomical and overall functional success was 98.8% (84/85) and 95.3% (81/85), respectively. Subjects with canalicular stenosis had a lower anatomical (75%) and functional (50%) success rates, which were statistically significant (p=0.00). Wound elongation (up to 8 mm) was observed in 3 cases, which did not require skin suturing. Mean patient satisfaction score for the appearance of incision was 99.2. CONCLUSION: Minimum incision (5 mm) no skin suture Ext-DCR offers high patient satisfaction and success rates.

Reliability of air bubble test in assessment of anatomical and functional success after external dacryocystorhinostomy.

PURPOSE: To assess the sensitivity and specificity of air bubble test (ABT) for anatomical and functional success after external dacryocystorhinostomy (Ext-DCR). METHODS: In a retrospective interventional case series, patients with nasolacrimal duct obstruction who had undergone Ext-DCR procedure were included. Functional success was defined as no symptom or mild excess tear in the cold weather and anatomical success as free irrigation at last follow-up time (at least 6 months). Air bubble test was performed by putting antibiotic drops into the eye and asking the patient to exhale while keeping the nose and mouth closed. Formation of bubbles inside the eye (hissing noise) was considered as positive test. Specificity, sensitivity, and positive and negative predictive values were then calculated for both anatomical and functional success. RESULTS: There were 85 procedures in 77 patients. Anatomical and overall functional success was 98.8% (84/85) and 95.3% (81/85), respectively. Air bubble test showed a sensitivity of 82.1% and specificity of 100% for the anatomical success after Ext-DCR. Sensitivity and specificity were 83.9% and 75% for the functional success. CONCLUSION: Positive ABT indicated no anatomical failure after Ext-DCR in this series.

Eighteen-point abobotulinum toxin a upper face rejuvenation: an eye plastic perspective on 845 subjects.

PURPOSE: To report the method and results of 18-point Abobotulinum toxin A (ABO-BTA, Dysport) upper face rejuvenation on 845 subjects. METHODS: In a retrospective chart review, all subjects (the first cycle of injection) with ABO-BTA upper face rejuvenation from 2003 to 2009 were included. Excluded were subjects with facial spastic disorders, injection after upper face lifting, and aberrant regeneration of facial nerves. Upper face rejuvenation included 18 points of injection at forehead creases (4), frown lines (5), bunny line (1), crow's feet (4 on both sides), and lower eyelid crease (4 on both sides). They were revisited in 10 to 14 days for assessment of the effects and possible touch-up injection. Demographics, year of injection, topical anesthetic usage, touch-up injection, and adverse effects (AE) were recorded. RESULTS: There were 845 subjects (85.8% women) whose age was below 40 in 49.3%. All but 68 (8%) were happy with the touch-up visit, 10 to 14 days after injection. Touch-up injection was performed in 8% of subjects mainly for the eyebrow asymmetry. AE (22/845, 2.6%) were bruise (15/845, 1.8%), blepharoptosis (3/845, 0.3%), remained eyebrow asymmetry after touch-up injection (2/845, 0.2%), and headache (2/845, 0.2%). They were significantly more in subjects with touch-up injection, younger than 40 years, and in the first and second year of experience (especially for the bruise). CONCLUSIONS: Eighteen-point ABO-BTA upper face rejuvenation had a low rate of AE in this series in which majority was bruise at the lateral canthal area. They were significantly more in the first years of experience, subjects younger than 40, and who had touch-up injections.

Purpose: To report a rare case of orbital dermoid cyst, involving the inferior rectus muscle, in a 26-year-old female presenting with proptosis and blurred vision in her right eye. Observations: The unique features of this case are discussed, including the location and contents of the cyst, the surgical approach, and the postoperative outcome. Conclusion and importance: The importance of considering dermoid cysts in the differential diagnosis of an orbital mass involving extraocular muscles and the need for a thorough evaluation to diagnose and manage these rare lesions.

Comparative efficacy of probing with or without intubation, and/or inferior turbinate fracture in simple congenital nasolacrimal duct obstruction: a randomized clinical trial.

To compare the success rates of probing with or without monocanalicular intubation, and/or inferior turbinate fracture in resolving simple congenital nasolacrimal duct obstruction (CNLDO). A randomized, double-blind clinical trial was conducted on children aged 12-36 months exhibiting symptoms of epiphora and/or mucous discharge along with a positive fluorescein dye disappearance test (DDT). Patients were randomly assigned to one of the following interventions: (1) probing; (2) probing and monocanalicular intubation; (3) probing and inferior turbinate fracture; (4) probing, inferior turbinate fracture, and monocanalicular intubation. Participants were categorized into two age groups (12-24 months and 24-36 months) and assessed for resolution of CNLDO three months post-surgery. Success was defined as the absence of epiphora or mucopurulent discharge and a negative DDT. Among the 201 participants, 51 underwent probing alone, 53 underwent probing with intubation, 47 underwent probing with turbinate fracture, and 50 underwent probing with turbinate fracture and intubation. No significant differences were observed in age, gender, or laterality of the disease between the groups (Ps > 0.05). While there was no significant difference in success rates among interventions in both age groups (Ps > 0.05), patients aged 24-36 months who underwent interventions involving intubation exhibited a significantly higher success rate compared to those without intubation (93.0% vs. 76.2%; P = 0.018). However, this difference was not observed in patients aged 12-24 months (95.7% vs. 92.9%; P = 0.551). Incorporating interventions such as intubation and/or turbinate fracture alongside conventional probing does not significantly alter the success rate of simple CNLDO resolution in children aged 12-24 months. However, older patients (24-36 months) may derive greater benefits from interventions involving intubation.

Transconjunctival lower blepharoplasty: a 2-sided assessment of results and subjects' satisfaction.

PURPOSE: To assess the results and satisfaction after transconjunctival lower blepharoplasty, evaluate the effect of associated aesthetic procedures on the satisfaction, and compare surgeon versus subjects' perspective on the results. METHODS: In a retrospective cross-sectional study, a chart review was performed on transconjunctival lower blepharoplasty procedures performed by 1 eye plastic surgeon from April 2003 to April 2009. Subjects with less than 6 months follow-up time or reoperation were excluded. Demographic data, associated surgical procedures, intra and postoperative complications, subjects and surgeon's perspectives on postoperative results, photographs (before and after the operation), and satisfaction score (Visual analogue scale score) at last follow-up time were recorded. RESULTS: There were 164 subjects (133 women, 81.1%) with mean age of 50.7 years (standard deviation=11.6, range: 23-80). Mean follow-up time was 22.8 months (standard deviation=11.5, range=6-60 months). Complications, observed by the surgeon and subjects, were undercorrected fat excision (4.9% vs. 3.7%), eyelid retraction (1.2% vs. 1.2%), and tear trough deformity (9.7% vs. 0.6%). Subjects reported less complication rate (5.4%) than surgeon (15.8%). Mean visual analogue scale score was 92.8 (standard deviation=0.36), which was significantly higher in subjects who had simultaneous upper blepharoplasty and lower in subjects with postoperative eyelid retraction. CONCLUSIONS: Transconjunctival lower blepharoplasty is associated with a high satisfaction. Subjects reported less complication rate than surgeon especially for tear trough deformity. Postoperative eyelid retraction significantly decreased and simultaneous upper blepharoplasty procedure significantly increased the satisfaction.

Reliability of fluorescein dye disappearance test in assessment of adults with nasolacrimal duct obstruction.

PURPOSE: To evaluate the role of fluorescein dye disappearance test (FDDT) in assessment of adults with primary acquired nasolacrimal duct obstruction (PANDO) and its correlation with age and severity of epiphora. METHODS: In a prospective, cross-sectional comparative study, FDDT at 2 (2-FDDT), 5 (5-FDDT), and 10 (10-FDDT) minutes were performed in 58 eyes of 58 patients with PANDO (case) and 58 eyes of 58 subjects without epiphora (control) between 2008 and 2010. Exclusion criteria were any disease, trauma, or medications that might have an effect on tear drainage system. Patients with functional or incomplete obstruction and upper lacrimal drainage system obstruction were excluded in the case group. FDDT and severity of epiphora were graded. RESULTS: Case and control groups were matched. 2-FDDT showed a sensitivity of 82.8%, specificity of 91.4%, positive predictive value of 90.6%, and negative predictive value of 84.1%. Sensitivity and negative predictive value decreased to 71.1% and 78.6% in 5-FDDT. 5-FDDT specificity and positive predictive value, however, increased to 94.8% and 93.5%, respectively. There was no statistically significant correlation between severity of epiphora and age with FDDT. CONCLUSIONS: FDDT is a simple, reliable, and highly specific test in assessment of adults with PANDO.

Severe unilateral congenital ptosis with poor levator function: tarsoconjunctival mullerectomy plus levator resection vs frontalis sling procedure.

AIM: To compare frontalis sling and tarsoconjunctival mullerectomy plus levator resection (TCMLR) in subjects with severe unilateral congenital ptosis with poor levator function (LF). METHODS: A prospective non-randomized non-blinded single center clinical trial. Fifty patients with severe unilateral congenital ptosis with poor LF were recruited. The frontalis sling and TCMLR were performed and the functional, cosmetic outcomes, complications, and success rate were evaluated at 1, 3, and 6mo postoperatively. The t-test, Chi-square, Fishers exact, and nonparametric Mann-Whitney tests were used by SPSS software. RESULTS: Frontalis sling and TCMLR procedures were performed on 26 and 24 patients respectively. The mean age was 10.97±10.67y. LF was significantly better in the TCMLR group at months 1, 3, and 6 (P=0.002). Lagophthalmos was more common in the TCMLR group (no significant difference). At month 3, mild punctate epithelial erosions were observed more in the frontalis sling group (P=0.002). Significant complete success rate of 1st and 6th month for the frontalis sling vs TCMLR groups were 50% vs 20.8% (P=0.02), and 38.4% vs 50% (P=0.03) respectively. CONCLUSION: Complete success rate of TCMLR is higher in long-term follow-up in contrast with the frontalis sling in the short-term. Transient complications are more detected in mid-term follow-ups in both groups.
