RESUMO

BACKGROUND Cataract surgery is associated with the development of late-onset age-related macular degeneration (AMD). The pathogenic mechanism is still not fully established. The purpose of this study was to evaluate the possible changes in central macula thickness (CMT) and subfoveal choroid thickness (SCT) after uneventful cataract surgery. MATERIAL AND METHODS A total of 65 eyes of 65 patients who underwent phacoemulsification and intracapsular lens implantation were included in this prospective study. Patients had not undergone previous ocular surgery and had no other ocular abnormality. CMT and SCT were measured at baseline and postoperatively at week 1 and months 1, 3, 6 and 12 via spectral domain optical cohorence tomography (SD-OCT). RESULTS CMT was 252.4±27.6 µm (mean ±SD) preoperatively, then 253.5±29.8, 256.1±28.7, 257.4±27.2, 253.18±23.7, and 252.8±21.7 µm at postoperative week 1 and postoperative months 1, 3, 6, and 12, respectively. There were insignificant changes in CMT, and it returned to baseline at six months after surgery (all p>0.05). SCT was 237.4±21.6 µm preoperatively, and 240.5±24.8, 241.2±25.7, 242.7±26.3, 243.1±24.2, and 244.2±21.4 µm at postoperative week 1 and postoperative months 1, 3, 6, and 12, respectively. Although there was an increase in SCT during follow-up, the difference between preoperative and postoperative values was not significant (p>0.05). CONCLUSIONS Uncomplicated phacoemulsification induces subclinical changes in CMT, probably due to the inflammatory insult of surgery, and CMT returns to baseline value. There were slight, insignificant increases in choroid thickness during follow-up, and this did not return to baseline during follow-up. Changes in the choroid after cataract surgery may provide clues to the development of late-onset AMD.

RESUMO

BACKGROUND: Knobloch syndrome is a rare, autosomal recessive, developmental disorder characterized by stereotyped ocular abnormalities with or without occipital skull deformities (encephalocele, bone defects, and cutis aplasia). Although there is clear heterogeneity in clinical presentation, central nervous system malformations, aside from the characteristic encephalocele, have not typically been considered a component of the disease phenotype. METHODS: Four patients originally presented for genetic evaluation of symptomatic structural brain malformations. Whole-genome genotyping, whole-exome sequencing, and confirmatory Sanger sequencing were performed. Using immunohistochemical analysis, we investigated the protein expression pattern of COL18A1 in the mid-fetal and adult human cerebral cortex and then analyzed the spatial and temporal changes in the expression pattern of COL18A1 during human cortical development using the Human Brain Transcriptome database. RESULTS: We identified two novel homozygous deleterious frame-shift mutations in the COL18A1 gene. On further investigation of these patients and their families, we found that many exhibited certain characteristics of Knobloch syndrome, including pronounced ocular defects. Our data strongly support an important role for COL18A1 in brain development, and this report contributes to an enhanced characterization of the brain malformations that can result from deficiencies of collagen XVIII. CONCLUSIONS: This case series highlights the diagnostic power and clinical utility of whole-exome sequencing technology-allowing clinicians and physician scientists to better understand the pathophysiology and presentations of rare diseases. We suggest that patients who are clinically diagnosed with Knobloch syndrome and/or found to have COL18A1 mutations via genetic screening should be investigated for potential structural brain abnormalities even in the absence of an encephalocele.

RESUMO

PURPOSE: This study aimed to evaluate the changes in retrobulbar blood flow by using color Doppler sonography in patients who had undergone intravitreal ranibizumab injection for neovascular age-related macular degeneration (AMD). METHODS: The study comprised 37 AMD patients who had undergone intravitreal 0.5 mg ranibizumab injection. The ophthalmic artery, central retinal artery, and short lateral posterior ciliary artery of both eyes of patients were evaluated by color Doppler sonography. Peak systolic velocity, end-diastolic velocity, and resistance index were calculated before injection, and after injection on day 7 and day 30. The pre- and postinjection values were compared using Wilcoxon signed rank test. RESULTS: In a comparison with the preinjection values of peak systolic velocity, end-diastolic velocity, and resistance index, the postinjection values at both day 7 and day 30 showed no statistically significant difference in ophthalmic artery, lateral posterior ciliary artery, and central retinal artery (p > 0.05). Similarly, for the same parameters, pre- and postinjection values in the uninjected fellow eye showed no statistically significant difference (P > 0.05). CONCLUSIONS: Intravitreal ranibizumab injection for neovascular AMD does not cause a significant change in the retrobulbar blood flow in either the injected eye or the fellow eye.

RESUMO

PURPOSE: To determine the distribution of central corneal thickness (CCT) and intraocular pressure (IOP) in a population of Turkish school children and to evaluate the relationships between these values and both age and gender. METHODS: A total of 30,320 eyes from 15,160 healthy school children aged 5-18 years were examined. CCT and IOP were measured using an ultrasonic pachymeter and a non-contact tonometer, respectively. Measurements were compared with age, gender, and parental consanguinity of subjects. RESULTS: The mean age of the school children was 10.43 ±â€…2.54 years. For right eyes, mean CCT was 557.91 ±â€…34.26 µm and mean IOP was 14.15 ±â€…2.87 mmHg. Mean CCT was significantly thicker in males compared to females (P < 0.0001). Mean IOP was significantly higher in females compared to males (P < 0.0001). CCT in children aged 14 years and older was significantly thinner than that in the younger age groups (P < 0.0001). There was a significant difference among the age groups for IOP (P < 0.05). No significant differences were observed in CCT or IOP related to parental consanguinity (P = 0.538, P = 0.319, respectively). CONCLUSION: Mean CCT in Turkish school children is of comparable thickness to that in Western school children. CCT reached adult values around 14 years of age in our children. Furthermore, males had thicker CCT than females. IOP was lower in males than females, and increased with age.

RESUMO

PURPOSE: To evaluate the effects of intravitreal moxifloxacin with or without dexamethasone on experimental Bacillus cereus endophthalmitis. METHODS: The right eyes of 21 New Zealand albino rabbits weighing 2-3 kg were used in this study. Each eye was inoculated with 1×10(6) colony-forming units of B. cereus microorganisms via intravitreal injection into the vitreous cavity, and an experimental model of B. cereus endophthalmitis was formed. The rabbits were separated into 3 groups: Group 1 was given 0.1 mL of balanced saline solution intravitreally, group 2 was given 50 µg of moxifloxacin, and group 3 was given 50 µg of moxifloxacin plus 400 µg of dexamethasone 24 h after the inoculation. Vitreous aspirates were taken for microbiological examination on the 3rd day. Clinical inflammation scores were evaluated on days 1, 7, and 14. The rabbits were killed on the 14th day, and the eyes were enucleated for histopathological examination. RESULTS: On the 7th day, only the vitreous scores of the treatment groups were significantly low compared with those of the control group (P<0.05). On day 14, the clinical scores of vitreous inflammation were 2.43±0.79, 1.43±0.53, and 1.29±0.49 in Groups 1, 2, and 3, respectively. The clinical scores of the treatment groups were significantly lower compared with those of the control group on day 14 (P<0.05). Histopathological scores were 2.43±0.79, 1.43±0.53, and 1.43±0.79 for the iris and 2.14±0.69, 1.57±0.53, and 1.14±0.38 for the vitreous in Groups 1, 2, and 3, respectively. Apart from the conjunctiva, the histopathological scores of the other tissues in the treatment groups were significantly lower compared with those of the control group (P<0.05). No significant differences were found in the histopathological or clinical scores among the treatment groups (P>0.05). Microbiological scores at day 14 were 151±6.43, 125.43±13.44, and 131.14±16.99 for Groups 1, 2, and 3, respectively. The microbiological scores of the treatment groups were significantly lower compared with those of the control group (P<0.05). CONCLUSIONS: Intravitreal moxifloxacin injection is effective in experimental B. cereus endophthalmitis. The addition of intravitreal dexamethasone may not significantly affect treatment efficacy.

RESUMO

Distinctive facial features consisting of hypertelorism, telecanthus, blepharophimosis, blepharoptosis, epicanthus inversus, periumbilical defects, and skeletal anomalies are seen in autosomal-recessive Carnevale, Malpuech, Michels, and oculo-skeletal-abdominal (OSA) syndromes. The gene or genes responsible for these syndromes were heretofore unknown. We report on three individuals from two consanguineous Turkish families with findings characteristic of these syndromes, including facial dysmorphism, periumbilical depression, mixed hearing loss, radioulnar synostosis, and coccygeal appendage. Homozygosity mapping yielded an autozygous region on chromosome 3q27 in both families. In one family, whole exome sequencing revealed a missense mutation, MASP1 c.2059G>A (p.G687R), that cosegregated with the phenotype. In the second family, Sanger sequencing of MASP1 revealed a nonsense mutation, MASP1 c.870G>A (p.W290X), that also cosegregated with the phenotype. Neither mutation was found in 192 Turkish controls or 1200 controls of various other ancestries. MASP1 encodes mannan-binding lectin serine protease 1. The two mutations occur in a MASP1 isoform that has been reported to process IGFBP-5, thereby playing a critical role in insulin growth factor availability during craniofacial and muscle development. These results implicate mutations of MASP1 as the cause of a human malformation syndrome and demonstrate the involvement of MASP1 in facial, umbilical, and ear development during the embryonic period.

RESUMO

OBJECTIVE: To compare the results of probing with and without endoscopy in cases of congenital nasolacrimal duct obstruction who had previously not undergone probing. METHODS: Fifty-one children with congenital nasolacrimal duct obstruction who underwent surgical intervention between June 2007 and April 2009 in our hospital were included in the study. Patients who had had previous probings were excluded from the study. Conventional probing was performed in 37 eyes of 25 patients, and probing with intranasal endoscopic visualization in 36 eyes of 26 patients. Diagnosis was based on history of epiphora since birth or shortly after, and fluorescein dye disappearance test. RESULTS: Thirty-two of 37 eyes (86.48%) were cured by probing. Of the 5 cases with complaints, 1 had lacrimal sac fistula. Thirty-four of 36 eyes (94.44%) were cured by probing guided by endoscope observation. Thirty-two cases had stenosis at the lower end of the nasolacrimal duct which required probing. In two cases the probe passed submucosally to the floor of the nose. In two cases a false passage was made at the upper end of the inferior meatus. In these cases, the operation was continued by repeating the process until the distal end of the nasolacrimal canal was seen to have been passed. CONCLUSION: Probing with endoscopy may be excessive in primary cases but in cases which have undergone unsuccessful probing, it is useful for visualization of anomalies in the lower nasolacrimal canal and to obtain the correct anatomic position for the probe.

RESUMO

BACKGROUND: Central serous chorioretinopathy is an idiopathic disorder that leads to serous neurosensory retinal detachment. The disorder is usually self-limited and resolves spontaneously; however, sometimes neurosensory retinal detachment persists. This form of the disorder is called chronic central serous chorioretinopathy (CCSC). OBJECTIVE: The aim of this study was to assess the effects of photodynamic therapy (PDT) on visual acuity with full-dose verteporfin for CCSC. METHODS: The eyes of patients with CCSC were included in the study. Ophthalmic examination including best-corrected visual acuity (BCVA), fundus examination, fluorescein angiography, and optical coherence tomography was performed before treatment and at 1, 3, 6, 9, and 12 months. PDT with full-dose verteporfin (6 µ/m(2) of body surface area) was applied only to areas of active leakage. BCVA was converted to a log of the minimum angle of resolution (logMAR) equivalent for statistical analysis. Central foveal thickness and BCVA between baseline and follow-up were compared. RESULTS: Seventeen eyes of 16 patients (13 males, 3 females; mean [SD] age, 39.75 [7.51] years; mean duration of follow-up, 13.06 [1.82] months) were used in the study. The mean (SEM) logMAR BCVA was 0.26 (0.07) at baseline and 0.04 (0.02) at 12 months. Mean logMAR BCVA values at baseline (0.259) and after treatment (0.112, 0.053, 0.047, 0.041, and 0.041 at 1, 3, 6, 9, and 12 months, respectively) differed significantly (P = 0.006, P = 0.005, P = 0.005, P = 0.005, and P = 0.005). There was a significant difference in the mean central foveal thickness at the final visit (169 µm) compared with the baseline value (383 µm; P < 0.001). BCVA decreased in one eye (20/20 vs 20/25) and persisted during follow-up; in the other 16 eyes, BCVA either increased (n = 10) or remained stable (n = 6). CONCLUSIONS: In this small, open-label study, patients with CCSC treated with a single course of PDT with full-dose verteporfin had significant improvement from baseline in BCVA and resolution of subretinal fluid accumulation and active leakage. Treatment was generally well tolerated, but one patient had worsening in BCVA.

RESUMO

PURPOSE: To evaluate the clinical efficacy of intravitreal bevacizumab (IVB) combined with panretinal photocoagulation in patients with open angle neovascular glaucoma (NVG). METHODS: Nine patients (9 eyes) with NVG participated in this study. Patients received IVB (1.25 mg) as the initial treatment for NVG and were followed up for at least 4 months. IVB was offered as the first treatment of choice to patients with NVG. Panretinal photocoagulation was performed as soon as feasible after the second week and completed in all patients the fourth week after IVB. The main outcome measures are resolution of INV, inhibition of peripheral anterior synechia (PAS), and controllability of intraocular pressure (IOP). RESULTS: The mean follow-up period was 5.6+/-1.4 months (range, 4-9 months). The mean IOP before treatment was 35.1+/-9.7 mmHg (range, 24-56) under medication before IVB treatment. After IVB and after combined treatment, the mean IOP was reduced to 22.8+/-8.1 mmHg (range, 9-33) and 13.0+/-4.0 mmHg (range, 7-20), respectively. The mean referral INV was 3.6+/-0.4 grade (range, 3-4) and reduced to 1.6+/-0.4 (range 1-2) grade after IVB and 0.6+/-0.8 (range 0-2) grade after combined therapy. By IVB, combined panretinal photocoagulation recurrence of INV was not observed. CONCLUSIONS: In NVG, IVB treatment can reduce iris and angle neovascularization and inhibits further PAS formation temporarily. Panretinal photocoagulation inhibits neovascularization constantly. Therefore, management of open angle NVG is more feasible with bevacizumab combined with panretinal photocoagulation.

RESUMO

Apert's syndrome is a rare form of craniosynostosis that exhibits with many ocular manifestations. We present two cases of Apert's syndrome. Our first case is a 10-year-old girl admitted with exotropia, V pattern and proptosis on examination. Investigations revealed coronal craniosynostosis, cleft palate, vaginal atresia and syndactyly of the hands and feet. The second case is a 5-year-old boy presented with hypertelorism, exotropia, dissociated vertical deviation and proptosis. Investigations revealed coronal craniosynostosis, bifid uvula and syndactyly of the hands and feet.

RESUMO

BACKGROUND: A pterygium is a fibrovascular overgrowth of degenerative bulbar conjunctival tissue that grows over the limbus onto the cornea. Although various approaches have been proposed for the treatment of pterygium, the common problem after these treatments is recurrence. OBJECTIVES: The goals of this study were to compare the efficacy of mitomycin C (MMC) and limbal-conjunctival autograft (LCAU) in preventing recurrence of primary pterygia and to monitor long-term adverse effects (AEs). METHODS: Patients undergoing pterygium surgery between February 2006 and May 2007 were assessed prospectively and randomly divided into 2 groups using a random number table. The MMC group underwent pterygium excision and received 0.02% MMC intraoperatively for 2 minutes. The LCAU group underwent pterygium excision and LCAU. Recurrence and AE rates of the 2 treatments were compared during the 1-year follow-up period. Assessors for pterygial recurrence were masked to treatment group. RESULTS: One hundred thirteen eyes (57 patients in the MMC group and 56 patients in the LCAU group) were included in the study. Thirteen of the patients (7 in the MMC group and 6 in the LCAU group) were withdrawn due to irregular attendance at follow-up visits or lack of sufficient dose and duration for postoperative topical antibiotic and steroid administration; their data were excluded from analysis. Fifty patients (MMC group: 26 men, 24 women; mean [SD] age, 48.0 [12.3] years; age range, 30-73 years; LCAU group: 27 men, 23 women; mean age, 49.0 [12.6] years; age range, 28-71 years) in each group completed the study. The mean (SD) length of the pterygium across the limbus was similar in the MMC group and the LCAU group (4.18 [1.27] vs 4.07 [1.24] mm). The mean follow-up period was also similar in the 2 groups (16.0 [1.9] vs 15.0 [1.7] months). The rate of recurrence was significantly greater in the MMC group than in the LCAU group (10 [20.0%] vs 2 [4.0%] patients; P=0.035). Seven patients (14.0%) in the MMC group experienced AEs: conjunctival cyst (3 patients), symblepharon (2), conjunctival granuloma (1), and dellen (1). In the LCAU group, 1 patient (2.0%; P=0.032 vs MMC group) experienced permanent graft edema. All patients in the LCAU group experienced transient graft edema, with recovery occurring in 3 to 4 weeks. There were no intraoperative complications and there was no graft rejection. CONCLUSIONS: Recurrence and postoperative AEs were less frequently observed in primary excision with LCAU than with MMC in these Turkish patients who completed the study. This study found that pterygium excision with LCAU was well tolerated and effective in these patients.

RESUMO

We report a rare case in which triamcinolone acetonide particles gathered on posterior lens capsule after injection of intravitreal triamcinolone acetonide. Intravitreal injection of triamcinolone acetonide is useful in the treatment of macular edema; however, accumulation of triamcinolone acetonide particles on the posterior lens capsule may decrease visual acuity and requires surgical treatment.

RESUMO

BACKGROUND: We report a case of inverted follicular keratosis (IFK) on the conjunctiva. A few cases of IFK have been reported in the literature, but it appears that IFK on the conjunctiva has never been reported. CASE: A 21-year-old man was referred for evaluation of a conjunctival mass. OBSERVATIONS: By slit-lamp biomicroscopy, an 8 x 5 x 3 mm mass was observed over the nasal conjunctiva adjacent to the limbus in the left eye. An excisional biopsy of the lesion was carried out. The results of a pathologic examination showed IFK. During the 9-month follow-up period, the patient had no recurrence of the lesion. CONCLUSION: IFK can be considered in the differential diagnosis of conjunctival masses as a rare specific lesion.

RESUMO

BACKGROUND: Ophthalmologists should be aware of the signs and symptoms of anthrax, although it is a rare disease in humans. We report our successful treatment of three patients with cutaneous lesions in the periorbital area. CASES: In this study, we report on the treatment of three female patients who were initially diagnosed as having preseptal cellulitis. OBSERVATIONS: Gram-positive robs were revealed in the microscopic examination of scrapings taken from the lesions. Bacillus anthracis was found in only two of the three scraping-material cultures. Intravenous penicillin G was administered in all cases. Black and necrotic eschar, which is characteristic of anthrax, developed on the eyelids of all three patients during treatment. At the final examinations of the patients after the completion of treatment, we recognized the development of cicatrisation, lagophthalmos, and slight ectropion in the upper eyelid of the first patient, and, in the second patient, restriction of upper eyelid movement and development of a corneal scar from exposure keratopathy and ectropion. The cutaneous lesions healed without any eyelid pathology in the third patient. CONCLUSION: Although it is a rare disease in humans, anthrax should be considered in the differential diagnosis of preseptal and orbital cellulitis.

RESUMO

PURPOSE: A prospective evaluation of the ocular blood flow velocity in patients with BehCet's disease was carried out to determine its changes. METHODS: Subjects were divided into three groups: those with ocular involvement in BehCet's disease (group I), those without ocular involvement in BehCet's disease (group II), and a control group (group III). Twenty-seven eyes in group I and 28 eyes each in groups II and III were investigated. The blood flow in the central retinal artery (CRA), ophthalmic artery (OA), nasal posterior ciliary artery (NPCA), and the temporal posterior ciliary artery (TPCA) was measured using color Doppler ultrasonography (CDU) to determine the peak systolic velocity (PSV), end diastolic velocity (EDV), and resistivity index (RI). The mean blood flow velocity of the central retinal vein (CRV) was also measured. These results were then compared among the three groups of subjects. RESULTS: The PSV values of CRA in groups I and II were found to be significantly lower than those in the control group ( P < 0.001, P = 0.018, respectively). The PSV values of CRA in group I were found to be significantly lower than those in group II ( P< 0.001). The EDV values of CRA in groups I and II were found to be significantly lower than those in the control group ( P< 0.001, P = 0.034, respectively). The EDV values of CRA in group I were significantly lower than those in group II ( P = 0.041). The PSV values of OA in group I were significantly lower than those in the control group ( P = 0.002). The EDV values of OA in group I were significantly lower than those values in group II or the control group ( P = 0.001 and P = 0.037, respectively). The PSV values of NPCA in group I were significantly lower than those in the control group ( P = 0.007). The PSV values of TPCA in groups I and II were significantly lower than those in the control group ( P< 0.001, P < 0.001, respectively). The EDV values of TPCA in group I were significantly lower than those values in group II or the control group ( P = 0.014 and P = 0.003, respectively). There were no significant differences in the mean blood flow values of the CRV among all three groups ( P > 0.05). CONCLUSIONS: There are significant reductions in the blood flow values of the orbital arteries in patients with BehCet's disease, and they are more evident in those with ocular involvement. This might be the result of occlusive vasculitis, which is frequently seen in the retinal vessels of patients with BehCet's disease.

RESUMO

BACKGROUND: Orbital myiasis cases are very rare worldwide. We are reporting this case caused by Hypoderma bovis because invasive parasitic larvae can cause massive destruction. CASE: An 85-year-old female patient was admitted to the Department of Ophthalmology of the Dicle University School of Medicine with the complaint of a wound in her right eye for over one year. Larvae had been in the same eye for one week. OBSERVATIONS: The clinical examination showed no light perception in her right eye. The eyelid was thickened and there was a necrotic lesion 3 x 4 cm in diameter, invading inferiorly into the upper side of the maxilla, superiorly to the roof of the orbita, medially to the lateral part of the nose, and laterally to the ossa zygomatica. Pathological examination of orbital tissue specimens confirmed basal cell carcinoma. CONCLUSIONS: Orbital exenteration, total maxillectomy and graft repair were conducted in the right eye. During the six-month follow-up period, orbital tomography was performed. No recurrence or metastasis was observed.
