Anterior uveitis following eyebrow epilation with alexandrite laser

WOS: 000215307400037PubMed ID: 26379448Ocular tissues are known to be sensitive to damage from exposure to laser emissions. This study reports the case of a female patient with acute unilateral anterior uveitis caused by alexandrite laser-assisted hair removal of the eyebrows. We report a 38-year-old female who presented with unilateral eye pain, redness, and photophobia after receiving alexandrite (755 nm) laser epilation of both eyebrows. Best corrected visual acuity was 20/20 in both eyes. Right eye examination was normal. Left eye examination showed conjunctival injection and 2+/3+ cells in the anterior chamber. Intraocular pressure and fundus examination were normal. Topical steroids and cycloplegic drops were prescribed for 3 weeks. At the end of the 3-week follow-up, best corrected visual acuity was 20/20, and intraocular pressure and fundus examination were normal in both eyes. The left eye was white, and the anterior chamber was clear. The patient continues to be monitored. In conclusion, without adequate protective eyewear, laser hair removal of the eyebrows with alexandrite laser can lead to ocular damage

Treatment of phthiriasis palpebrarum and crab louse: Petrolatum jelly and 1% permethrin shampoo

WOS: 000215278400032PubMed ID: 26451147Phthiriasis palpebrarum is an uncommon cause of blepharoconjunctivitis in which Pthirus pubis infest the eyelashes. We report a case of unilateral phthiriasis palpebrarum with crab louse. A 45-year-old man presented with conjunctival hyperaemia and moderate itching associated with irritation, and crusty excretions of the eyelashes in the left eye. Careful slit-lamp examination revealed many lice and nits in left eye and mild conjunctival hyperaemia. No abnormality was found in the right eye. On dermatologic examination, only one louse was found at the pubic area. The patient was treated effectively with petrolatum jelly (Vaseline) and 1% permethrin shampoo (Kwellada 1% shampoo). At the end of the firstweek no louse or nitwas present on eyelashes and pubic area

Performance of the SRK/T formula using A-Scan ultrasound biometry after phacoemulsification in eyes with short and long axial lengths

Medical Technologies National Conference, TIPTEKNO 2015 -- 15 October 2015 through 18 October 2015 -- 118954Background: The SRK/T formula is one of the third generation IOL calculation formulas. The purpose of this study was to evaluate the performance of the SRK/T formula in predicting a target refraction ±1.0D in short and long eyes using ultrasound biometry after phacoemulsification. Methods: The present study was a retrospective analysis, which included 38 eyes with an AL < 22.0 mm (short AL), and 62 eyes ?24.6 mm (long AL) that underwent uncomplicated phacoemulsification. Preoperative AL was measured by ultrasound biometry and SRK/T formula was used for IOL calculation. Three different IOLs were implanted in the capsular bag. The prediction error was defined as the difference between the achieved postoperative refraction, and attempted predicted target refraction. Statistical analysis was performed with SPSS V21. Results: In short ALs, the mean age was 65.13 ± 9.49 year, the mean AL was 21.55 ± 0.45 mm, the mean K1 and K2 were 45.76 ± 1.77D and 46.09 ± 1.61D, the mean IOL power was 23.96 ± 1.92D, the mean attempted (predicted) value was 0.07 ± 0.26D, the mean achieved value was 0.07 ± 0.63 D, the mean PE was 0.01 ± 0.60D, and the MAE was 0.51 ± 0.31D. A significant positive relationship with AL and K1, K2, IOL power and a strong negative relationship with PE and achieved postoperative was found. In long ALs, the mean age was 64.05 ± 7.31 year, the mean AL was 25.77 ± 1.64 mm, the mean K1 and K2 were 42.20 ± 1.57D and 42.17 ± 1.68D, the mean IOL power was 15.79 ± 5.17D, the mean attempted value was -0.434 ± 0.315D, the mean achieved value was -0.42 ± 0.96D, the mean PE was -0.004 ± 0.93D, the MAE was 0.68 ± 0.62D. A significant positive relationship with AL and K1, K2 and a significant positive relationship with PE and achieved value, otherwise a negative relationship with AL and IOL power was found. There was a little tendency towards hyperopic for short ALs and myopic for long ALs. The majority of eyes (94.74 %) for short ALs and (70.97 %) for long ALs were within ±1 D of the predicted refractive error. No significant relationship with PE and IOL types, AL, K1, K2, IOL power, and attempted value, besides with MAE and AL, K1, K2, age, attempted, achieved value were found in both groups. Conclusion: The SRK/T formula performs well and shows good predictability in eyes with short and long axial lengths

Corneal flap thickness with the Moria M2 single-use head 90 microkeratome in 72 consecutive LASIK procedures

WOS: 000395338300001PubMed ID: 28424534Purpose: This study aimed to evaluate the accuracy and consistency of corneal flap thickness in laser-assisted in situ keratomileusis (LASIK) with the Moria M2 single-use head 90 microkeratome. Methods: The central corneal thickness of 72 (37 right, 35 left) eyes of 37 patients was measured by ultrasonic pachymetry preoperatively and intraoperatively after flap cut. The Moria M2 single-use head 90 microkeratome was used to create a superior hinged flap in all eyes. The right eyes were always operated on before the left eyes in each patient, using the same blade in all bilateral cases. All patients underwent LASIK for myopia and/or myopic astigmatism using VISX Star S4 platform. Results: The mean preoperative spherical equivalent refraction was -3.55 +/- 2.30 D (range: -0.625 to -11.00 D), preoperative central corneal thickness by ultrasonic pachymetry was 541 +/- 26.82 mu m (490-600 mu m) and steepest K was 44.08 +/- 1.49 D (40-46.75 D) in all eyes. The mean flap thickness was 136.97 +/- 20.07 mu m (106-192 mu m), 131.2 +/- 19.5 mu m (91-192 mu m), and 134.16 +/- 19.85 mu m (91-192 mu m) in the right, left, and both eyes, respectively. A positive significant relationship was found between flap thickness and preoperative ultrasonic pachymetry thickness. No significant relationship was found between flap thickness and the age, preoperative spherical equivalent, and preoperative steepest K. The difference between the first and second eyes was not significant. There were no major intraoperative and postoperative complications in all eyes. Conclusion: The Moria M2 single-use head 90 microkeratome cut relatively thicker flaps than were intended. The flap thickness range was quite wide. This was a disadvantage for the accuracy and consistency of corneal flap thickness

MRI results of patients with acute isolyted cranial nerve palsies

AIM: To investigate the magnetic resonance imaging (MRI) results of patients complaining from diplopia with ocular nerve palsy.MATERIAL and METHODS: A routine ophthalmic examination was performed, a neurological consultation was requested, and cranial MRI was performed for all patients. The image results were sorted into four groups: ischemic lesions, demyelinating disease lesions, tumors, and no lesions. White matter gliosis and cerebral infarcts were included in the ischemic lesion group. The medical histories of the patients were acquired from medical records. The chi-squared test was used to analyze the relationship between age and cranial MRI images and to analyze the relationship between the image and paresis type. The statistical significance threshold was set at p<0.05, unless otherwise stated.RESULTS: Ischemic MRI images were the most common image type seen in our study. Third nerve paresis was significantly correlated with ischemic cerebral lesions observed by MRI (p=0.009). Furthermore, lesions were significantly correlated with patients aged above 50 years (p=0.004). There were no significant correlations between fourth or sixth nerve paresis and cranial ischemic images (p=0.680 and p=0.678, respectively). There were two instances of cerebral artery aneurysm, three instances of cerebral infarct, and one instance of intracranial mass, all in patients aged over 50 years.CONCLUSION: Although our patients had minimal or nonexistent neurological symptoms, some had serious cranial pathologies. These pathologies were commonly seen in patients aged over 50 years. We recommend performing MRI on all patients with binocular diplopia

Intraoperative and early postoperative flap-related complications of laser in situ keratomileusis using two types of Moria microkeratomes

WOS: 000341838700012PubMed ID: 24531872The purpose of this study is to describe the incidence, management, and visual outcomes of intraoperative and early postoperative flap-related complications of laser in situ keratomileusis (LASIK) surgery using two types of Moria M2 microkeratomes. This retrospective analysis was performed on 806 primary LASIK cases. The intraoperative and early postoperative flap-related complications were identified and categorized according to type of Moria microkeratome. There were 52 intraoperative and early postoperative complications-one case of partial flap (0.124 %), one case of free flap (0.124 %), one case of small flap (0.124 %), 13 cases of epithelial defect (1.61 %), 12 cases of flap striae (1.49 %), 10 cases of diffuse lamellar keratitis (1.24 %), 10 cases of interface debris (1.24 %), three cases of epithelial ingrowth (0.37 %), and one case of microbial infection (0.124 %). The overall incidence of flap complications was 6.45 %. There were 27 right eye (6.73 %) and 25 left eye (6.17 %) complications. The incidence of complications with the Moria automated metallic head 130 microkeratome was 4.22 % and with the Moria single-use head 90 microkeratome was 2.23 %. We observed one culture-negative interface abscess which was cured with surgical cleaning and intensive medical treatment. The most common complication encountered was epithelial defects, followed by flap striae. Our study showed that LASIK with a microkeratome has a relatively low incidence of intraoperative and early postoperative flap complications.

Predicting the refractive outcome and accuracy of IOL power calculation after phacoemulsification using the SRK/T formula with ultrasound biometry in medium axial lengths

WOS: 000403959400001PubMed ID: 28670106Purpose: To evaluate the accuracy of the SRK/T formula using ultrasound (US) biometry in predicting a target postoperative refraction of +/- 1.00D in eyes with medium axial length (AL) that underwent phacoemulsification. Methods: The present study was a retrospective analysis, which included 538 eyes with an AL from 22.0 to 24.60 mm that underwent phacoemulsification and foldable intraocular lens (IOL) implantation (six different IOLs) in the bag. Preoperative AL was measured by US biometry and IOL power (IOLp) was calculated with the SRK/T formula. Patients had a complete ophthalmic examination, preoperatively and 1, 7, and 30 days after surgery. The achieved spherical equivalent (SE) and the prediction error (PE) were calculated. The prediction error was defined as the difference between attempted predicted target refraction and the achieved postoperative SE refraction. Statistical analysis was performed with SPSS V21. Results: The mean age of the patients was 66.96 +/- 9.67 years, the mean AL was 23.29 +/- 0.62 mm, the mean K1 was 43.62 +/- 1.49D, the mean K2 was 43.69 +/- 1.53D, the mean IOL power was 21.066 +/- 1.464D, the mean attempted (predicted) SE was -0.178 +/- 0.266D, and the mean achieved SE was -0.252 +/- 0.562D. The mean PE (difference between predicted and achieved SE) showed a relatively hyperopic shift (mean +/- standard deviation: 0.074 +/- 0.542D, ranging from -1.855 to 2.170D, P=0.001). A total of 93.87% of eyes were within +/- 1.00D of the PE and 92.75% of eyes within +/- 1.00D of achieved postoperative refraction. A total of 39 eyes (7.25%) had a refractive surprise. A total of 32 of 39 eyes were more myopic than -1.00D and 7 of them were more hypermetropic than +1.00D. There was no correlation between the mean PE and IOL type, AL, K1, K2, and IOLp. There were a positive statistically significant correlation between PE and age (r=0.095; P=0.028) and a negative statistically significant correlation between achieved SE and AL (Spearmans r=-0.125; P=0.04), and age (r=-0.141; P=0.01). Conclusion: The IOLp calculation using the SRK/T formula with US biometry may demonstrate very good postoperative refractive outcomes in medium eyes with a few refractive surprises

Investigating estrogen and progesterone receptors in the lacrimal sacs of individuals with and without chronic dacryocystitis

Objectives: Chronic dacryocystitis is usually seen in middle-aged or older women, suggesting that decreased estrogen and progesterone serum levels may be a causative factor in the disease pathology. However, the occurrence of the disease in premenopausal females and males suggests that there may be more to the explanation than the level of female sex hor-mones. The purpose of the present study was to investigate estrogen and progesterone receptor positivity in the lacrimal sacs of individuals with and without chronic dacryocystitis. Methods: The study group included 50 female and 20 male patients diagnosed with chronic dacryocystitis. Lacrimal sac samples were taken during a dacryocystorhinostomy. The control group comprised 29 cadavers with no evidence of lacrimal system pathology in the health records. The samples were obtained transconjunctivally. Lacrimal sac samples from both groups were stained with the estrogen and progesterone receptor protein antigen. Fisher's exact test and a chi-square test were used to compare the receptor positivity results of premenopausal and postmenopausal women, and samples of those with dacryocystitis and cadaver sacs without the disease. Results: In the control group, estrogen receptor positivity was observed in the samples of 2 premenopausal females. In the study group, estrogen receptor positivity was seen in 4 premenopausal females. There was no significant difference in estrogen receptor positivity between the premenopausal and postmenopausal female groups (p=0.41). A similar result was not established between the premenopausal and postmenopausal females in case group (p=0.056). No comparison was made of the progesterone receptor because only 1 example of progesterone receptor positivity was found in a pre-menopausal female in the dacryocystitis group. Conclusion: Estrogen receptor positivity did not seem to be a factor in chronic dacryocystitis physiopathology

Comparison of different formulas for intraocular lens power calculation using a new optical biometer

Purpose. - To evaluate and compare the predictability of different formulas for intraocular lens (IOL) power calculation using a new optical biometer (Aladdin). Methods. - This prospective cross-sectional study included 70 eyes of 70 patients who underwent uneventful phacoemulsification with IOL implantation. Preoperative IOL power calculations were performed using the Aladdin optical biometer. Postoperative actual refractive errors and errors predicted by the SRK/T, SRK II, Holladay 1, Hoffer Q and Haigis formulas were analyzed. The mean estimation error (EE), mean absolute estimation error (AEE) and the percentage of eyes within +/- 0.50 and +/- 1.00 D of the target refraction for each of five formulas were calculated and compared. This analysis was also repeated in three groups formed based on axial length (AL) (group 1: 24 mm). Results. - In the overall study group, the smallest mean AEE was provided by the Holladay 1 formula, however there was no statistically significant difference in the mean AEE's predicted by the five formulas (P = 0.34). The highest percentage of eyes within +/- 0.50 and +/- 1.00 D of the target refraction was also found by using Holladay 1 (71% and 97%). SRK/T provided smallest mean AEE for groups 1 (n = 13) and 3 (n = 16). In group 2 (n = 41), the smallest mean AEE was obtained using Holladay 1. Conclusions. - Based on the Aladdin biometric data used in our study, better results can be obtained using SRK/T formula in eyes with short or long AL. The Holladay 1 formula may be preferred in eyes with moderate AL

Anterior segment optical coherence tomography evaluation of corneal epithelium healing time after 2 different surface ablation methods

WOS: 000349405000011PubMed ID: 25630007Objectives: To compare epithelial healing time following laser epithelial keratomileusis (LASEK) and photorefractive keratectomy (PRK) with anterior segment optic coherence tomography (AS-OCT). Methods: This prospective interventional case series study comprised 56 eyes of 28 patients that underwent laser refractive surgery in the Department of Ophthalmology, Medipol University Medical Faculty, Istanbul, Turkey, between March 2014 and May 2014. Each patient was randomized to have one eye operated on with PRK, and the other with LASEK. Patients were examined daily for 5 days, and epithelial healing time was assessed by using AS-OCT without removing therapeutic contact lens (TCL). Average discomfort scores were calculated from ratings obtained from questions regarding pain, photophobia, and lacrimation according to a scale of 0 (none) to 5. Results: The mean re-epithelialization time assessed with AS-OCT was 3.07 +/- 0.64 days in the PRK group, 3.55 +/- 0.54 days in the LASEK group, and the difference was statistically significant (p=0.03). Mean subjective discomfort score was 4.42 +/- 0.50 in the PRK eyes, and 2.85 +/- 0.44 in the LASEK eyes on the first exam day (p=0.001). The score obtained on the second (p=0.024), and third day (p=0.03) were also statistically significant. The fourth (p=0.069), and fifth days scores (p=0.1) showed no statistically significant difference between groups. Conclusion: The PRK showed a statistically significant shorter epithelial healing time, but had a statistically significant higher discomfort score until the postoperative fourth day compared with LASEK.الطريقة: هذه الدراسة التداخلية املرتقبة للحاالت املسلسلة تتضمن 56 ً عينا من 28 ً مريضا الذين تلقوا جراحة الليزر االنكسارية في قسم أمراض العيون في مستشفى كلية الطب جامعة ميدي بول، اسطنبول، تركيا، في الفترة ما بني مارس 2014م مايو 2014م. كل مريض خضع للعملية ألحدى عينيه بطريقة )الالزيك( والعني االخرى بطريقة )بي آر كي(. مت االختيار بني العينني بطريقة عشوائية. مت فحص كل مريض بعد العملية بشكل دوري وملدة خمسة أيام، ومت حساب الزمن املستغرق لشفاء الغشاء الظهاري للقرنية باستخدام الـ ) أي اس- أو سي تي( بدون ازالة العدسات الالصقة املداوية. مت حساب معدل درجات االنزعاج عن طريق سؤال املريض عن األلم، رهاب الضوء و تدمع العني بنقاط من الصفر )مبعنى ال يوجد( الى 5. النتائج: املتوسط الزمني لعودة التظهرن املقاس بطريقة الـ ) أي اس- أو سي تي( كانت: 64.0±07.3 يوم في مجموعة الـ)بي آر كي( و 54.0±55.3 في مجموعة الـ )الالزيك( والفرق بني املجموعتني كان ً واضحا ً إحصائيا )بي= 03.0 .)املتوسط االنزعاجي الغير املوضوعي كان 50.0±42.4 في العيون التي خضعت للـ )بي آر كي( و 44.0±85.2 في العيون التي خضعت للـ )الالزيك( في اليوم األول للفحص. املعدالت التي مت احلصول عليها لدرجة االنزعاج في اليومني الثاني والثالث كانت ً أيضا ً واضحة احصائيا، )بي= 024.0 و بي=03.0 على التوالي(. ً اليومني الرابع واخلامس لم يظهر درجات واضحة احصائيا بني املجموعتني )بي=069.0 و بي=1.0 )على التوالي. اخلامتة: أظهرت طريقة الـ )بي آر كي( زمنا أقصر اللتئام الغشاء الظهاري ً الذي كان واضحا ً إحصائيا ولكنه في الوقت نفسه أظهرت درجة انزعاج أكثر حتى اليوم الثالث بعد العملية
