Postoperative levator function change in patients with unilateral myogenic versus aponeurotic blepharoptosis.

PURPOSE: To compare the change in levator function (LF) after levator resection in patients with unilateral myogenic (MP) and aponeurotic ptosis (AP). METHODS: In a prospective study, patients of >5 years old were included from June 2015 to April 2017. Other types of ptosis, associated strabismus and previous eyelid surgery were excluded. Eyelid examination and photography were performed before and at least 6 months after surgery. Success was defined as Margin reflex distance 1 (MRD1) of within 0.5 mm of the unoperated side. All procedures (levator resection) were performed by or under supervision of one surgeon. RESULTS: There were 58 patients in the MP (mean age: 19.2 years) and 20 in the AP (mean age: 49.5) group with median follow up of 10 months. LF was significantly improved from 5.8 to 7.3 mm in the MP and from 11.8 to 13.6 mm in the AP group. LF improvement was not observed in 17.2% of MP and 25% of AP group (P = 0.5). Mean preoperative LF was significantly (Odd ratio = 1.8) higher in patients with than without LF improvement in the MP group. It was significantly reverse in the AP group (Odd ratio = 0.38). A significantly positive (r = 0.30) and negative (r = -0.72) correlations were observed between preoperative LF and LF improvement in the MP and AP groups, respectively. Success was observed in 90% of AP and 84.5% of MP group. In order of frequency, undercorrection, overcorrection, and contour abnormality were the reasons for failure. No variable significantly affected the success rate in either group. CONCLUSION: Majority of MP and AP showed postoperative LF improvement. While higher preoperative LF was significantly correlated with LF improvement in the MP, it was reverse in the AP group. Success rate was not significantly different between the groups and no factor significantly affected the success in either group.

Change in Lower Eyelid Position After Ptosis Repair in Patients With Unilateral Myogenic Versus Aponeurotic Blepharoptosis.

PURPOSE: To compare preoperative and postoperative lower eyelid scleral show in patients with unilateral myogenic (MP) and aponeurotic (AP) ptosis, analyze the factors correlated with them, and assess the rate of postoperative lower eyelid symmetry in both groups. METHODS: Patients (older than 5 years old) with unilateral MP (58) and AP (20) were included from June 2015 to April 2017. Excluded were patients with previous eyelid surgery, strabismus, levator function of ≤3, and associated procedures. Margin reflex distance (MRD) 1 and 2 and levator function were measured by the same observer before and at least 6 months after the ptosis repair. RESULTS: Lower scleral show was observed in 56.8% and 80% of MP and AP, respectively. Margin reflex distance 2 was significantly (r = -0.37, p = 0.002) associated with MRD1 in the MP group (multiple regression analysis). Both groups showed a significant improvement of MRD2, postoperatively resulting in symmetric MRD2 in 91.4% of MP and 80% of AP group. It was not changed in 43% of MP and 25% of AP group. Multiple regression analysis showed that preoperative MRD2 was the only significant factor associated with postoperative improvement of scleral show in the MP group. CONCLUSIONS: Lower scleral show was significantly improved after ptosis repair in both MP and AP. The more severe MP was significantly associated with more severe preoperative scleral show. Preoperative MRD2 was the only factor predicting postoperative improvement of scleral show in the MP. No factor was significantly associated with MRD2 in the AP group.

Eyelash Ptosis in Unilateral Myogenic and Aponeurotic Blepharoptosis: A Prospective, Controlled, Before- and After-Study.

PURPOSES: The purposes of this study were to compare lash ptosis (LP) with contralateral eyelid in patients with unilateral myogenic (MP) and aponeurotic (AP) ptosis before and after the ptosis repair and to assess the correlation between postoperative eyelid height and LP symmetry. METHODS: Patients older than 5 years were included from June 2015 to April 2017. Eyelid examination, LP grading (0-3), and photography were performed before and at least 6 months after ptosis repair. Success of ptosis repair (levator resection) was defined as margin reflex distance 1 within 0.5 mm of the contralateral eyelid; LP improvement, as at least 1 grade improvement at the last follow-up; and LP symmetry, as 2 eyelids being within 1 grade. RESULTS: There were 58 patients with MP and 20 with AP, with mean age of 19.2 and 49.5 years and median follow-up of 10 months. Lash ptosis was observed in 89.5% of ptotic and 33.3% of control eyelids. Mean LP grade was significantly higher in the MP (1.5) than in the AP (1.1), which significantly improved to 0.6 and 0.4, respectively. However, it persisted in 50.9% of MP and 31.2% of AP postoperatively. Lash ptosis symmetry was observed in 97.4% of patients, which was not correlated with margin reflex distance 1 symmetry. Lower levator function was the only significant factor correlated with LP. CONCLUSION: Lash ptosis was significantly worse in MP than in AP. Lower LF was correlated with more severe LP. Ptosis repair resulted in significant improvement of LP and its symmetry with the contralateral eyelid. Lash ptosis symmetry did not correlate with eyelid height symmetry postoperatively.

Visual and Anatomical Outcomes of Spironolactone Therapy in Patients with Chronic Central Serous Chorioretinopathy.

PURPOSE: To evaluate the effect of spironolactone on chronic central serous chorioretinopathy (CSC). METHODS: In this prospective interventional case series, patients with chronic CSC were treated with spironolactone (25 mg daily) for at least 6 weeks. If the subretinal fluid (SRF) had not completely resolved by this time, treatment was continued, and the dosage was increased to 25 mg twice daily. Primary outcome measure was the change in maximum SRF height at the final follow-up visit, as detected by optical coherence tomography. Secondary outcome measures were changes in best corrected visual acuity (BCVA) and central macular thickness (CMT). RESULTS: Sixteen eyes of 14 patients with chronic CSC were enrolled. Mean follow-up time was 6.4 ± 4.3 months. Baseline BCVA was 0.54 ± 0.44 logarithm of the minimum angle of resolution (log MAR), which improved to 0.42 ± 0.43 log MAR at the final visit (P = 0.04). Mean CMT decreased from 282.69 ± 103.23 µm at baseline to 236.75 ± 90.10 µm at final visit (P = 0.11), and the mean of maximum SRF height decreased from 155.63 ± 95.27 µm at baseline to 77.19 ± 95.68 µm at the final visit (P = 0.04). SRF resolved completely in seven eyes (43.75%). CONCLUSION: In eyes with persistent SRF due to CSC, spironolactone therapy was associated with a statistically significant decrease in maximum SRF height, as well as an improvement in BCVA.

Tear Film, Lacrimal Drainage System, and Eyelid Findings in Subjects With Anophthalmic Socket Discharge.

PURPOSE: To compare the results of tear film and lacrimal drainage system tests between anophthalmic socket and normal eye and assess discharge characteristics and frequency of prosthesis removal (questionnaire), eyelid function, and meibomian glad dysfunction (MGD). DESIGN: Prospective masked case control. METHODS: Subjects (≥6 years and ≥6 months of wearing prosthesis) with unilateral acquired anophthalmic socket discharge were included. Excluded was ocular adnexal abnormality of any reason and incomplete tests. The subjective questionnaire was completed. Blinking rate, lagophthalmos, eyelid laxity, MGD, Schirmer test, tear meniscus height, and dye disappearance test were assessed by a masked examiner. Another masked examiner performed an irrigation test 1 week later and interpreted the scintigraphy images at the end of the study. RESULTS: Included were 50 subjects (mean age: 31.3 years, mean prosthesis wear: 96.1 months). Discharge was frequent or very frequent in 85%, mucoid or mucopurulent in 90%, and moderate to severe in 86% of the subjects. MGD in 58%, lagophthalmos in 80%, and eyelid laxity in 46% were observed. Anophthalmic socket sides showed a significantly lower tear production and higher tear drainage obstruction. Subjects with frequent prosthesis removal had a significantly (P = .02) greater lagophthalmos and blinking rate (P = .04). The blinking rate was also significantly greater in subjects with higher frequency of discharge (P = .04). CONCLUSION: Tear film impairment (aqueous and lipid) and lacrimal drainage obstruction should be considered in subjects with anophthalmic socket discharge. A significantly higher blinking rate and lagophthalmos were found in subjects with higher frequency of prosthesis removal.

Statins and postoperative infections: a randomized clinical trial.

BACKGROUND: Observational studies, rather than randomized trials, revealed that statins might be associated with other benefits. OBJECTIVES: The present study aimed at evaluating the preventive effects of lovastatin when used as a prophylactic agent for early and late infective complications after surgery. PATIENTS AND METHODS: A total of 149 patients undergoing elective intracranial and spinal surgeries, were enrolled in a double- blind randomized clinical trial in the department of neurosurgery of a teaching hospital. An amount of 20 mg lovastatin and the same dose of placebo, one day before the operation and three days after the surgery, were used for cases and controls, respectively. The patients were evaluated for local and systemic infections during hospitalization and 10, 30, 60 and 90 days after discharge. RESULTS: A total of 149 patients, 78 men and 71 women with a mean age of 40.3 ± 16.5, were assigned to prophylactic protocols. 46 and 103 patients were in the case and control groups, respectively. Eight episodes of infection were detected, including six bacterial meningitis and two episodes of hospital- acquired pneumonia. All of the patients with documented postoperative infections were part of the placebo group, however, there were no significant statistical differences between the groups (P = 0.059). CONCLUSIONS: In spite of the differences between the two groups, the results did not significantly support the preventive effect of statins in postoperative infections.
