Objective: Determine the safety of ACR-128 phakic lenses for high myopia correction one year after implantation. Method: A cross-sectional study was conducted of 67 eyes of 36 patients with myopia corrected with ACR-128 phakic lens implants (31 in both eyes and 5 in one eye). Pre- and postoperative determination was made of ocular tension, endothelial cell loss by count, cell variation coefficient and hexagonality, as well as of postoperative complications and lens position with respect to the endothelium and the crystalline lens. Statistical analysis was based on the paired T-test with a significance level of 95 percent Results: Mean age was 28.06 ± 6.14 (25 women and 11 men). An immediate complication was hypotonia: RE: 1 (3.03 percent), LE: 1 (2.94 percent). Pupil irregularity was mediate: RE: 1 (3.03 percent), LE: 1 (2.94 percent) and late: RE: 1 (3.03 percent), LE: 2 (5.88 percent). Total average ocular tension was 14.09 ± 2.51 preoperative and 14.22 ± 2.64 postoperative (p = 0.90). Cell count was 2667.27 ± 228.72 preoperative and 2591.96 ± 301.21 postoperative, with 2.94 percent total endothelial loss 75.31 ± 237.41 (p = 0.06). Differences were not found in the variation coefficient (p = 0.60) or in hexagonality (p = 0.57). Lens position was 2.09 mm with respect to the endothelium and 1.08 mm with respect to the crystalline lens. Conclusions: ACR-128 phakic lens implantation for high myopia correction is a safe procedure with no postoperative complications or modifications in ocular tension or the corneal endothelium after one year's follow-up(AU)

Morphology and epidemiological study of idiopathic scoliosis among primary school students in Chaozhou, China

BACKGROUND@#Idiopathic scoliosis (IS) affects patients' quality of life, yet there have been few reports of its morphology and epidemiological study in the southeast region of China. The aim of this study is to access the curve characteristics, prevalence, and factors associated with IS in Chaozhou city.@*METHODS@#A cross-sectional study was performed in 2018, in which scoliosis screening was conducted among 5497 primary school students in Chaozhou city. Then, a case-control study based on the screening involving 2547 children was followed for the exploration of the associated factors. The questionnaires covering demographic characteristics, postural habits, cognition and self-sensation of scoliosis, and physical conditions were addressed for the investigation. ORs with 95%CIs were calculated based on logistic regression analysis to evaluate the factors associated with scoliosis.@*RESULTS@#The prevalence of IS among primary school students was 6.15% in Chaozhou city, with 4.04% for males and 8.71% for females. The average Cobb angle was 15° (range 8 to 37°). Multiple logistic regression analysis suggested that female (OR=2.45), BMI (OR=0.67), having myopia (OR=1.49), self-sensation of scoliosis with symptoms (OR=5.52), insufficient sleep time (OR=2.65, 3.33), and less exercise time (OR=7.09, 7.29) were significantly associated with IS.@*CONCLUSIONS@#The prevalence of IS among primary school students in Chaozhou was at an average level, and it was significantly higher in females than in males. Lower body mass, having myopia, insufficient sleep time, and lower physical activity were associated with IS.

Effectiveness of Toric Orthokeratology in the Treatment of Patients with Combined Myopia and Astigmatism

PURPOSE: The purpose of this multi-institute, single-group clinical trial was to evaluate the effectiveness and safety of toric orthokeratology lenses for the treatment of patients with combined myopia and astigmatism. METHODS: A total of 44 patients were included in this clinical trial. The patients ranged in age from 7 to 49 years, with myopia of -0.75 to -6.0 diopters (D) and astigmatism of 1.25 to 4.0 D. After excluding 21 subjects, 23 subjects (39 eyes) were analyzed after toric orthokeratology lens use. The subjects underwent ophthalmologic examination after 1 day and 1, 2, 3, and 4 weeks of wearing overnight toric orthokeratology lenses. RESULTS: A total of 19 subjects (31 eyes) completed the trial after five subjects (eight eyes) dropped out. In the patients who completed the study by wearing lenses for 4 weeks, the myopic refractive error decreased significantly by 2.60 ± 2.21 D (p < 0.001), from -3.65 ± 1.62 to -1.05 ± 1.64 D. The astigmatic refractive error were also significantly decreased by 0.63 ± 0.98 D (p = 0.001), from 2.07 ± 0.83 to 1.44 ± 0.99 D. The mean uncorrected and corrected visual acuities before wearing the lenses were 2.14 ± 0.80 logarithm of the logMAR (logMAR) and 0.05 ± 0.13 logMAR, respectively, which changed to 0.12 ± 0.30 logarithm of the logMAR (p < 0.001) and 0.01 ± 0.04 logMAR (p = 0.156) after 4 weeks. No serious adverse reactions were reported during the clinical trial. CONCLUSIONS: Our results suggest that toric orthokeratology is an effective and safe treatment for correcting visual acuity in patients with combined myopia and astigmatism.

Refraction and eye anterior segment parameters in schizophrenic patients / Refração e parâmetros do segmento anterior ocular em pacientes com esquizofrenia

ABSTRACT Purpose: To evaluate the difference in terms of refractive errors and anterior segment parameters between schizophrenic patients and healthy volunteers. Methods: This study compared 70 patients (48 men) who were diagnosed with schizophrenia with a control group of 60 (35 men) who were similar in terms of age, gender, education, and socioeconomic level. Anterior segment examination was performed using a Scheimflug system. Axial length and lens thickness (LT) were measured using optic biometry. The following tests were administered to the psychiatric patient group: Brief Psychiatric Rating Scale (BPRS), Scale for the Assessment of Negative Symptoms (SANS), and Scale for the Assessment of Positive Symptoms (SAPS). Results: Mild myopia was detected in both the schizophrenic and control groups, with no statistically significant difference (p>0.005). Corneal volume (CV), anterior chamber volume (ACV), anterior chamber depth (ACD), and central corneal thickness (CCT) values were lower in the schizophrenic group, and there was a statistically significant between-group difference (p=0.026, p=0.014, p=0.048, and p=0.005, respectively). LT was greater in schizophrenics, and the difference was found to be statistically significant (p=0.006). A statistically significant negative correlation was found between SAPS and cylinder values (p=0.008). The axial eye length, cylinder value, pupil diameter, mean keratometric value, and anterior chamber angle revealed no statistically significant difference between the groups (p>0.05). Conclusion: No statistically significant difference was detected in terms of refraction disorders between schizophrenics and the healthy control group, while some differences in anterior chamber parameters were present. These results demonstrate that schizophrenics may exhibit clinical and structural differences in the eye. .

RESUMO Objetivo: Avaliar se existem diferenças em relação aos erros refracionais e parâmetros do segmento anterior entre pacientes com esquizofrenia e voluntários saudáveis. Métodos: Este estudo comparou 70 pacientes diagnosticados com esquizofrenia (48 homens) com um grupo controle de 60 pacientes, semelhantes em relação à idade, sexo, escolaridade e nível socioeconômico (35 homens). O exame do segmento anterior foi realizado com o sistema Scheimflug; os comprimentos axiais do olho e a espessura do cristalino foram avaliadas por meio de biometria óptica. Os seguintes testes foram aplicados ao grupo de pacientes psiquiátricos: Brief Psychiatric Rating Scale (BPRS), Scale for the Assessment of Negative Symptoms (SANS), e Scale for the Assessment of Positive Symptoms (SAPS). Resultados: Miopia leve foi detectada em ambos os grupos de esquizofrenia e de controle, sem diferença estatisticamente significativa (p>0,005). Volume de córnea (CV), volume da câmara anterior (ACV), profundidade da câmara anterior (ACD) e paquimetria central da córnea (CCT) apresentaram valores menores no grupo de esquizofrênicos e houve diferença estatisticamente significativa entre os dois grupos (p=0,026, p=0,014, p=0,048 e p=0,005, respectivamente). A espessura do cristalino (LT) foi maior em esquizofrênicos e a diferença foi estatisticamente significativa (p=0,006). Foi encontrada uma correlação negativa estatisticamente significativa entre SAPS e os valores cilíndricos (p=0,008). O comprimento axial do olho, o valor do cilindro, o diâmetro pupilar, a ceratometria média e o ângulo da câmara anterior não revelaram nenhuma diferença estatística entre os grupos (p>0,05). Conclusões: Não foi detectada diferença estatisticamente significativa em relação aos transtornos de refração entre os esquizofrênicos e o grupo controle, enquanto algumas diferenças nos parâmetros de câmara anterior estavam presentes. Estes resultados demonstram que esquizofrénicos podem ...

Macular hole in juvenile X-linked retinoschisis

An 18 year-old male with no antecedent of trauma, systemic syndrome or myopia was referred for surgical treatment of a full thickness macular hole in the left eye. A more careful inspection revealed discrete foveal cystic changes in the fellow eye and subtle peripheral depigmented retinal pigment epithelial changes in both eyes. A spectral-domain optical coherence tomography [SD-OCT] scan confirmed, in addition to the full thickness macular hole in the left eye, microcystic spaces in the nuclear layers of both retinae. The diagnosis of X-linked retinoschisis was confirmed with a full field electroretinogram displaying the typical negative ERG. Macular holes are uncommon in the young and those complicating X-linked retinoschisis are rare. This report highlights the importance of investigating the presence of a macular hole in a young patient and illustrates the clinical and SD-OCT clues beyond the foveal center which led to the correct diagnosis of X-linked juvenile retinoschisis.

The Correlation of Differences in the Ocular Component Values with the Degree of Myopic Anisometropia

PURPOSE: To determine the relationship between the differences in the ocular component values with the degree of anisomyopia. METHODS: Refraction, corneal power (CP), and biometry were examined in 50 myopic adults with refractive differences (RD) over 1.50 diopters (D). Ocular components were measured by ultrasound biometry and keratometry. The correlation between the differences in the ocular component values with the degree of anisomyopia was analyzed by linear regression analysis. RESULTS: Among 50 adults with anisomyopia, 5 had RD from 1.50 to 2.99 D, 11 had RD from 3.00 to 3.99 D, 9 had RD from 4.00 to 5.99 D, 12 had RD from 6.00 to 7.99 D, 7 had RD from 8.00 to 11.99 D, and 6 had > or =12.00 D. There was no significant correlation between the ocular components (CP, crystalline lens thickness [LT], and anterior chamber depth [ACD], and the length from the cornea to the posterior surface of the lens [ACD + LT]) and the RD (p > 0.05). The RD showed a significantly positive correlation with vitreous chamber depth (VCD), and axial length (r = 0.963, p < 0.0001). CONCLUSIONS: The severity of anisomyopia was not correlated with the between-eye differences in the anterior chamber values of the eye (CP, ACD, LT, ACD + LT). The severity of anisomyopia was significantly correlated with the between-eye differences in VCD.

Clinical Characteristics of Glaucomatous Subjects Treated with Refractive Corneal Ablation Surgery

PURPOSE: To evaluate the clinical characteristics of newly diagnosed glaucomatous subjects who had a history of refractive corneal ablation surgery (RCAS). METHODS: Sixty-eight glaucomatous subjects who had a history of RCAS and 68 age- and visual field (VF) mean deviation-matched glaucomatous subjects with no history of RCAS were included. Intraocular pressure (IOP), central corneal thickness (CCT), VF, and retinal nerve fiber layer thickness determined by optical coherence tomography were assessed. Parameters were compared between patients with and without a history of RCAS. Between-eye comparisons in the same participant (more advanced vs. less-advanced eye, in terms of glaucoma severity) were performed in the RCAS group. RESULTS: With similar levels of glaucoma severity, those with a history of RCAS showed significantly lower baseline IOP and a thinner CCT than the eyes of individuals without a RCAS history (13.6 vs. 18.7 mmHg, 490.5 vs. 551.7 micrometer, all p < 0.001). However, the extent of IOP reduction after anti-glaucoma medication did not significantly differ between the two groups (17% vs. 24.3%, p = 0.144). In the between-eye comparisons of individual participants in the RCAS group, the more advanced eyes were more myopic than the less-advanced eyes (-1.84 vs. -0.58 diopter, p = 0.003). CONCLUSIONS: Eyes with a history of RCAS showed a similar level of IOP reduction as eyes without such a history after anti-glaucoma medication. Our finding that the more advanced eyes were more myopic than the less-advanced eyes in the same participant may suggest an association between glaucoma severity and myopic regression.

[Rhegmatogenous retinal detachment Eye research Center-Mashhad University of Medical Sciences]

Evaluation of epidemiology and seasonal variation of Rhegmatogenous Retinal Detachment [RRD], in patients undergoing retinal detachment surgery. Medical records of 416 patients admitted in KHATAM eye hospital [Mashhad, IRAN] were reviewed between years 2000 to 2008. Information about sex, age, season and month of incidence and operation and concomitant risk factors of patients, were gathered and analyzed. Average age of patients was 41 years old. Most of the cases of the disease were observed in the age group of above 6- y/o [35%]. The frequency of the RRD was higher in male patients than in females. [Ratio: 1.7 to 1]. Distribution of our cases in different seasons showed no significant difference between them [P value = 0.142]. The highest and lowest rate of RRD was observed in October and September respectively with October having 51 patients [12.3%] and September having 23 patients [5.5%]. Myoia and pseudophakia were most common risk factors. There was no statistically significant relationship between age and month [and season] of incidence [or diagnosis and surgical procedure] of the RRD, likewise for gender. This study showed more RRD in male patients. Patients above than 60 years old have greater risks of incidence of RRD. No seasonal incidence pattern for RRD was founded; however, most of cases occurred in October, and at least in September

Risk factors associated with pre-senile cataract

To determine frequency of various risk factors associated with presenile cataract among patients schedule for cataract surgery. Study was conducted at Abbasi Shaheed Hospital and Karachi Medical Dental College between October 2007 and September 2009. Patients of cataract of age 30-55 years were selected. Presence of risk factors like diabetes mellitus, high myopia, occupational exposure to metal work, atopic dermatitis and smoking were noted. Visual acuity, anterior and posterior segments were examined and axial length was measured. Two hundred fifty four patients satisfying inclusion criteria were selected. These included 181 male [mean age 44.7 years] and 73 females [mean age 43.8 years]. Unilateral eye involvement was present in 108 patients while bilateral involvement was present in 146 patients. Risk factors frequency was diabetes [26%], high myopia [16.1%], smoking [15%], metallic exposure [3.1%], atopic dermatitis [2%] while 37.8% were idiopathic. Significant difference were found in frequency of risk factors [p=0.004] and mean age according to presence of risk factors [p=0.001]. While no significant association was found of age with risk factors [p=0.7] and gender [p=0.24]. Our study shows that idiopathy contributed to most of the cases of presenile cataract followed by diabetes mellitus, high myopia and smoking

Conventional Epi-LASIK and Lamellar Epithelial Debridement in Myopic Patients with Dermatologic Keloids

We report the outcome of conventional epipolis laser in situ keratomileusis (Epi-LASIK, flap-on) and lamellar epithelial debridement (LED; Epi-LASIK, flap-off) in myopic patients with dermatologic keloids. Three patients, who were all noted to be susceptible to keloid scarring, received conventional Epi-LASIK in their right eyes and LED in their left eyes. The patients were followed-up for 6 to 21 months after their surgeries, and the outcomes were then evaluated. In case 1, the preoperative spherical equivalent (SE) was -6.5 diopters (D) in the right eye (OD) and -6.25 D in the left eye (OS). At 21 months postoperatively, the uncorrected visual acuity (UCVA) was 20 / 12.5 in both eyes. In case 2, the preoperative SE was -5.25 (OD) / -6.00 (OS). After six months, the postoperative UCVA was 20 / 12.5 in both eyes. In case 3, the preoperative SE was -4.5 (OD) / -2.0 (OS). The UCVA at the six-month follow-up was 20 / 12.5 in both eyes. No adverse events, including corneal haze, occurred in any of the patients. All three of our patients reported excellent visual outcomes following both conventional Epi-LASIK and LED, despite their histories of keloid formation. The present cases suggest that both Epi-LASIK and LED may be safe and effective techniques for myopic patients with dermatologic keloids.

Clinical Characteristics and Outcomes of Cataract Surgery in Highly Myopic Koreans

PURPOSE: To evaluate the clinical characteristics and outcomes of cataract surgery in highly myopic Korean subjects. METHODS: We retrospectively reviewed the medical records of 694 eyes of 694 patients who underwent cataract surgery. The case group included 347 eyes of 347 patients whose axial lengths (AXL) were > or =26.00 mm, and the control group included 347 eyes of 347 patients with AXL between 22.00 and 25.99 mm. Cataract density was determined preoperatively using the Pentacam Scheimpflug imaging system. We compared age at operation, cataract type, coexisting disease, visual prognosis, and complications. RESULTS: The mean age at the time of the operation was 59.60 +/- 12.28 years in the case group and 67.47 +/- 11.36 years in the control group. The case group had a larger proportion of nuclear cataracts and posterior subcapsular cataracts (PSC), 40.63% and 26.22%, respectively, versus 25.07% and 11.82%, respectively, in the control group. Postoperative corrected visual acuity showed a negative correlation with AXL (R2 = 0.172), and severe funduscopic findings were related to poor visual prognosis (p = 0.05). The incidence of retinal detachment in the case group after cataract surgery was 1.72%, compared with 0.28% in the control group. CONCLUSIONS: Highly myopic eyes tend to develop cataracts earlier than normal eyes and to have a higher prevalence of coexisting disease and complications, such as retinal detachment. Nuclear cataracts and PSC were more common in the highly myopic group. Poor visual prognosis was associated with longer axial length and retinal myopic degeneration.

One Sister and Brother with Mirror Image Myopic Anisometropia

We report a case of one sister and brother with mirror image myopic anisometropia. One sister and brother complained visual disturbance. The sister was 10 years 11 months old, and brother was 8 years 4 months old. Full ophthalmic examinations were performed, including slit lamp examination, intraocular pressure, keratometry, anterior chamber depth, axial length, fundus examination and the cycloplegic refraction. The cycloplegic refractive power was -15.50 dpt cyl.+4.50 dpt Ax 85degrees (right eye), -1.00 dpt cyl.+0.50 dpt Ax 90degrees (left eye) in the sister; -1.75 dpt cyl.+2.25 dpt Ax 90degrees (right eye), -9.50 dpt cyl.+4.00 dpt Ax 80degrees (left eye) in the brother. The co-occurrence of severe myopic anisometropia in a sister and brother is extremely rare. The present case suggests that severe myopic anisometropia may be related by genetic inheritance.

Fibrinous anterior uveitis following laser in situ keratomileusis.

A 29-year-old woman who underwent laser in situ keratomileusis (LASIK) for myopic astigmatism in both eyes presented with severe pain, photophobia and decreased visual acuity in the left eye eight days after surgery. Examination revealed severe anterior uveitis with fibrinous exudates in the anterior chamber, flap edema and epithelial bullae. Laboratory investigations for uveitis were negative and the patient required systemic and intensive topical steroids with cycloplegics to control the inflammation. This case demonstrates that severe anterior uveitis may develop after LASIK and needs prompt and vigorous management for resolution.

Surgical treatment of heavy eye syndrome; report of two cases

To report the clinical features and surgical outcomes of two patients with heavy eye syndrome who underwent partial Jensen's procedure. A 21-year-old man and a 24-year-old woman with high myopia [-18 and -8 diopters, respectively], high axial length [27.5 and 24.6 ram], progressive esotropia [40 and 50 prism diopters], hypotropia [5 and 2 prism diopters], abduction limitation, and inferior displacement of the lateral rectus on computed tomography were diagnosed with heavy eye syndrome and underwent partial Jensen's procedure. The technique consisted of splitting the lateral and superior recti from their insertion up to the equator and uniting their superior and temporal halves respectively, with non-absorbable sutures without scleral fixation. Two months postoperatively, esotropia was reduced to 10 prism diopters in case #1 and to 25 prism diopters in case #2; limitation of abduction was also considerably diminished. Patients with heavy eye syndrome, large angle esotropia and limitation of abduction, may benefit from partial Jensen's procedure which is a simple and safe surgical option

Lateral fixation of sclera to the periosteum with medial rectus disinsertion for severe myopic strabismus fixus.

Myopic strabismus fixus is characterized by severe ocular motility restriction with the development of progressive esotropia and hypotropia. Management of severe cases with strongly positive forced duction test can be challenging. We describe a longstanding case of myopic strabismus fixus, which was managed by bilateral medial rectus disinsertion and scleral fixation laterally to the periosteum.

Manejo del estrabismo en el alto miope / Management of strabismus in high myopia

Se analiza un grupo de 12 personas con estrabismo asociado a alta miopía, en términos de su presentación clínica, cirugía realizada y sus resultados. En 7 de éstos pacientes se realizó un tipo de unión entre los músculos rectos superior y lateral (técnica de Yokohama), pero se consideraron diferentes enfoques quirúrgicos sobre el recto medio. Se obtuvieron buenos resultados en la mayoría de los casos, observándose solamente 2 casos que requirieron reoperación.

A group of 12 patients with strabismus associated to high myopia is analyzed in terms of clinical presentation, surgery performed and its results. In 7 of these patients a type of muscular union between superior and lateral rectus (Yokoyama's technique) was done, but different approaches to the medial rectus were considered. Good results were obtained in most cases with only 2 patients requiring reoperations.

Phacoemulsification using iris-hooks for capsular support in high myopic patient with subluxated lens and secondary angle closure glaucoma.

We report an unusual case of angle closure glaucoma in a 78-year-old highly myopic female patient. The patient did not show any preoperative signs of subluxation of lens. However, the capsular bag was noted to be unstable during surgery. The patient was managed with phacoemulsification of lens using a novel method of iris hooks for stabilization of capsular bag during surgery.

Healing pattern of myopic macular hole based on optical Coherence Tomography [OCT]

To evaluate the different patterns in the healing of myopic macular holes with regard to the clinical appearance, OCT pattern and visual prognosis. A prospective non-randomized study was done on thirty patients from the outpatient clinic at Ain Shams University Hospital. All had retinal detachment due to a myopic macular hole. They were divided into three groups according to the post-operative OCT pattern of healing: group [A] with U pattern including 10 patients, group [B] with V pattern including 9 patients and group [C] including 11 patients. For all patients a complete ophthalmic examination and OCT were done pre- and post-operative. Thirty patients with a mean age of 50.1 years and 76.66% were females. The mean preoperative Log MAR was 2.11 +/- 0.30 in group [A], 2.2 +/- 0.26 in group [B] and 2.19 +/- 0.40 in group [C]. The mean postoperative Log MAR was 1.26 +/- 0.26 in group [A], 1.31 +/- 0.30 in group [B] and 1.92 +/- 0.54 in group [C]. Postoperative clinical hole pattern in group was F+O [flat and open] in 6 patients [20%], F+C [flat and closed] in 19 patients [63.33%] and E+O [elevated and open] in 2 patients [6.66%]. Postoperative OCT pattern was U pattern in 10 patients [33.33%], V pattern in 9 patients [30%] and W pattern in 11 patients [36.66%]. Post operative mean OCT hole size in group [A] was 370.9 +/- 207.29 micro m, in group [B] was 405.8 +/- 175.10 micro m and in group [C] was 550.7 +/- 344.3 micro m. As in idiopathic macular holes, there are three patterns of healing in myopic macular holes which form U, V and W patterns and which correlate with a clinical pattern of healing and visual prognosis
