RESUMO

AIM: To evaluate, on the basis of two-year observations, the effectiveness of intravitreal treatment with Ranibizumab in patients with diabetic macular edema (DME) unresponsive to the previous laser treatment. Cohort and Methods: A retrospective study evaluates 29 eyes of 29 patients with diffuse DME unresponsive to their previous laser treatment. The group of the patients consisted of 16 males (55.1%) and 13 females (44.8%); their mean age was 71.3. The mean duration of diabetes mellitus was 13 years (3-20). 19 patients (65.5%) were treated with insulin, 10 patients (34.4%) were treated with peroral antidiabetics (PAD); the mean HbA1c value was 52 mmol/l. The treatment was started with 3 initial doses of intravitreal injections of Ranibizumab 0.5 mg. There was a one- -month interval between the applications. Subsequent evaluations and administrations of the following injections were made in the pro re nata (PRN) mode; the check-ups were carried out every month during the first year and on average every 3 months in the second year. The monitored parameters: the best corrected visual acuity (BCVA) measured on ETRDS (Early Treatment Diabetic Retinopathy Study) optotypes, the central retinal thickness (CRT). These parameters were monitored prior to the treatment and then in the 3rd, 6th, 9th, 12th, 18th and 24th months. RESULTS: A statistically significant improvement in the mean value of BCVA was detected. From the initial 65.4 ±10.61 letters it improved by 11.2 letters (p.

RESUMO

AIMS: Present the use of Optical Coherence Tomography Angiography (OCTA) in vitreoretinal interface diseases and results of macular capillary network evaluation before and after idiopathic macular hole surgery (IMD). METHODOLOGY: Prospective evaluation of functional results, anatomical and OCTA findings before and after IMD surgery. The group consists of 8 eyes of eight patients. Preoperatively and 1, 3 and 6 months after surgery, the best corrected visual acuity (BCVA) was examined, fundus photography was performed, examination of the macula by spectral-domain optical coherence tomography (SD OCT), determination of the stage of IMD according to Gases and also OCTA examination. The area of the foveal avascular zone (FAZ) and vascular density (VD) were evaluated by using of the OCTA. The operation was performed in all cases by transconjunctival suture 25G vitrectomy by one surgeon, always peeling the inner limiting membrane. An expansive gas, 7x 20% SF6, 1x 15% C3F8, was used for vitreous tamponade. RESULTS: In all 8 cases, the primary closure of the IMD occurred after the operation. The mean BCVA improved statistically significantly from 0.74 to 0.48 logMAR (p = 0.0023). The average FAZ area decreased from 0.345 mm² to 0.25 mm² after surgery (p = 0.0458). The mean VD increased from 7.93 mm-1 to 8.38 mm-1 (p = 0.2959). CONCLUSIONS: Assessment of the macular capillary network in patients with diseases of the vitreoretinal interface offers new findings and important details that can lead to prognostic information and a better understanding of the pathogenesis of the disease. We demonstrated a statistically significant reduction in FAZ in the eyes after successful IMD surgery and an indirect relationship between the improvement of BCVA and the change in FAZ area in our cohort.

RESUMO

PURPOSE: To evaluate the safety and clinical efficacy of ranibizumab (Lucentis) in the treatment of choroidal neovascularization (CNV) caused by diseases other than age-related macular degeneration (AMD). PATIENTS: 21 patients with mean age 61  17.2 years (min 16, max 85) with CNV due to causes other than AMD, in particular pathological myopia (n=11), angioid streaks (n=3), central serous chorioretinopathy (n=2), North Carolina macular dystrophy (n=1), dominant familial drusen (n=1) and idiopathic CNV (n=3). METHODS: The patients were treated at the Ophthalmology Department of the University Hospital in Hradec Kralove with three monthly initial intravitreal injections of ranibizumab 0.5 mg with subsequent treatment regimen pro re nata (PRN). The best corrected visual acuity (BCVA) was evaluated on the ETDRS optotypes (Early Treatment Diabetic Retinopathy Study), central retinal thickness (CRT) was measured by optical coherent tomography (OCT) (Zeiss, Cirrus). These parameters were evaluated before start of the study and then at 1 (BCVA only), 4, 8, and 12 months during treatment. We also evaluated the possible occurrence of ocular and systemic side effects. RESULTS: Statistically significant improvement in the mean of BCVA score of 11.4 letters (p.

RESUMO

INTRODUCTION: Diabetic macular edema (DME) is the most frequent cause of decreased vision in patiens with diabetes type 2. DME is caused by increased permeability of macular capillaries. The aim of our study was to retrospectively evaluate the results of micropulse laser treatment, 577 nm wavelength, in pacients with DME with follow-up three months and one year. METHODS: The retrospective trial with one year follow-up includes 63 eyes of 37 patients with diabetic macular edema treated from September 2015 to January 2017.  Most patients had diabetes type 2 (34 patients), 3 patients had diabetes type 1. Diffuse DME was diagnosed in 54 eyes, focal DME in 9 eyes. Most of the patients (42 eyes) suffered from non proliferative diabetic retinopathy, 21 eyes showed signs of proliferative retinopathy. DME lasted on average for 29 months before initiating with micropulse laser (median 21 months). On average 1,56 laser visits were needed for the treatment of 1 eye, usually in 3 months interval. Photocoagulation of macula was performed in all patients by micropulse laser, 577 nm wavelenght/IQ 577TM IRIDEX). We used 5 % duty cycle. The average glycated hemoglobin in the group was 66,8 mmol/mol, maximal 100 mmol/mol. Estimated data were statistically evaluated by Friedman and Dunn´s test. RESULTS: At the end of 1 year period we found out improvement in BCVA (increase of at least 5 letters of ETDRS charts) in 20 eyes, 25 eyes showed stabilisation of BCVA (alltogether 71 % of the group), in 18 eyes we found out decrease of BCVA of more than 5 letters of ETDRS charts. On average we estimated decrease of visual acuity from 62 to 61,1 letters (p > 0,05). After one year we estimated 63 µm CRT decrease on average, from 442 µm to 379 µm (p= 0,0124). CONCLUSION: In our group of DME patiens treated by micropulse laser we have estimated BCVA stabilisation and signifiant improvement of macular edema in ¾ eyes, confirmed by OCT. We have estimated clinically significant decrease of macular edema in the whole group with one-year follow-up.

RESUMO

INTRODUCTION: The aim of this work is to evaluate our own results of surgical treatment of retinal detachment in immature newborns. Retinopathy of prematurity (ROP) is one of the most complicated ocular disorders, both in terms of diagnosis and therapy. It is a potentially blinding illness that arises from the incomplete development of the bloodstream of the neuroretina of preterm infants. Currently, the most effective therapy is ablation of the avascular retina by laser photocoagulation or cryocoagulation. Despite this treatment, the immature retina may develop it´s detachment. METHODOLOGY: We report 2 case-reports, retrospective results of 4-eyes in 2 patients with severe ocular and overall complications of prematurity. The ocular background of preterm babies was investigated in arteficial mydriasis by an indirect ophthalmoscope, and later with the RetCam photographic device. The ROP stages were evaluated according to the ICROP classification. All eyes were treated with cryo-retinopexy at the threshold stage of ROP, followed by intraocular surgery for progression of traction retinal detachment. The surgical technique was a 3-port 25-G PPV (pars-plicata vitrectomy) with insertion of ports 1.5 mm from limbus. The PPV was performed using the Constellation (ALCON) operating unit, controlling the intraocular pressure for 15 torr. The assessment of visual acuity was performed according to the scale: no light perception (no response of the child to light), light sensitivity (positive or negative reaction to illumination), fixation of light. RESULTS: The retina stayed attached in all operated eyes, more in each case-report. CONCLUSION: Contemporary vitreoretinal surgery allows for the anatomical success of traction retinal detachment surgery during ROP already in neonatal age.Key words: retinal detachment, retinopathy of prematurity, PPV, surgery.

RESUMO

UNLABELLED: Punctate Inner Choroidopathy (PIC) is a rare idiopathic ocular inflammatory disease. It occurs mostly in young, myopic, otherwise healthy women. Symptoms of the disease include acute vision decrease associated with central and paracentral scotoma. In 80% of cases PIC occur bilaterally. We report the case of a woman at the age of twenty-five, who was treated for PIC. Due to the finding of active inflammatory deposit in the retina of the left eye and low visual acuity was recommended corticosteroid therapy with a good therapeutic effect. KEY WORDS: Punctate Inner Choroidopathy (PIC), white dot syndromes.

RESUMO

Macular edema due to retinal vein occlusion is the second most common cause of vascular vision impairment. The authors refer two case reports that describe different response to treatment with OZURDEX, biodegradable injectable implant slowly releasing 700 µg dexamethasone. Treatment with corticosteroids is effective also in the case of cystic retinal edema, but its effect can be temporary. The most common adverse events are elevation of intraocular pressure and cataract development.

RESUMO

Rhegmatogenous retinal detachment (RRD) is the separation of the sensory retina from the pigment epithelium (RPE). RRD is caused by a retinal tear in the periphery and the vitreoretinal (VR) traction, which allows access of the vitreous fluid to the subretinal space. Treatment of symptomatic retinal detachment is currently surgical only. Surgical options are intraocular and extraocular. This is the retrospective evaluation of the group of 17 eyes of 17 patients with RRD, which were operated by scleral buckling. Patients were 9 men and 8 women, age range 19-61 (median 46) years. The observation period is 1-13 months (median 7). The possible types of external interventions procedure were used only two: the radial plombage (in one case double) and cerclage. 15 patients (88 %) were phakic, and 2 were pseudophakic. In 12 eyes (71 %) were the quadrant RRDs, 2 eyes had dialysis in periphery of the retina, 1x it was the top half and 1x bottom half, and 1 patient had a subtotal RRD. In 9 (53 %) cases were used type of operation cryocoagulation with radial buckle and in 8 cases cryocoagulation with the cerclage. In four cases, was injected the gas tamponade into the vitreous at the end of the surgery. Primary attaching the retina occurred in 16 cases (94 %) and the retina remained flat in 14 eyes (82.4% ), in 2 cases occurred re-detachment (11.7 %). Preoperative best corrected visual acuity (BCVA) ranged from hand movement to 20/20 (average Snellen equivalent 20/63) and postoperative BCVA was 1/50 - 20/20 (average 20/50). Improving BCVA was statistically significant (Wilcoxon p=0.01). We consider the cryosurgical procedure for phakic eyes as the gold standard of the surgical treatment of uncomplicated rhegmatogenous retinal detachment. The main reason for the eventual failure of this technique is persistent vitreous traction and proliferative vitreoretinopathy (PVR).

RESUMO

PURPOSE: Rhegmatogenous retinal detachment is a serious condition that can significantly impair visual function, even after a successful surgery. One of the complications that can significantly impair visual acuity in the postoperative period is a development of the epimacular membrane (ERM). The aim of this work is to monitor the effect of peeling of the internal limiting membrane (ILM) in the macula at the anatomical and functional results in the postoperative period, especially with regard to the development of ERM. METHODS: Prospective study of 21 eyes, which underwent peeling of ILM during pars plana vitrectomy for rhegmatogenous retinal detachment (on detached macula). The ILM peeling was done without using decalin during this procedure. We tested best corrected visual acuity (BCVA) and followed fundus biomicroscopic findings. Proliferative vitreoretinopathy (PVR) was evaluated according to the recommendations of the Retina Society Terminology Committee. To exclude the development of ERM in the macula optical coherence tomography (OCT) was performed at the end of the 18-month follow-up period. RESULTS: In total, the results of 21 eyes of 21 patients who underwent PPV for rhegmatogenous retinal detachment were evaluated. In all of them was during PPV performed ILM peeling on detached macula, these are followed prospectively. ILM peeling without using decalin was sufficient in all eyes. All eyes with ILM peeling did not develop ERM at the end of the follow-up period. CONCLUSIONS: ILM peeling during PPV for rhegmatogenous retinal detachment reduces the risk of developing secondary ERM.

RESUMO

Every eye surgery has its pitfalls and possible complications. Even after properly and noncomplicated orbital or intraocular surgery there can develop a loss of visual acuity or visual field. In the perioperative period was on the operated eye for epimacular membrane (23G pars plana vitrectomy) retinal arterial occlusion with fatal consequences for visual function. Entrance visual acuity decreased from 20/63 to counting fingers. Risk factors for age-related and underlying diseases were accompanied by systemic hypotension and mild anemia. Commonly available topical and general therapy did not lead to any significant improvement.

RESUMO

AIM: The aim of the study was to establish the efficacy of anti VEGF (Vascular Endothelial Growing Factor) drugs in the treatment of wet form ARMD (Age-Related Macular Degeneration) in everyday clinical practice in the Department of Ophthalmology, Faculty Hospital, Hradec Králové, Czech Republic, E.U., in patients registered in the Czech national registry AMADEUS. MATERIAL AND METHODS: Retrospective study with 24 months follow-up period. In the group were evaluated 143 eyes of 140 patients, out of them were 77 women (65.8 %), of average age 73.09 (71.69 - 74.48) years, and 40 men (34.2 %) of average age 74 (58 - 85) years. All of the patients were completely examined before the beginning of the treatment; during the treatment were, except the standardized eye examination, in patients treated with ranibizumab the color fundus photography and Optical Coherence Tomography (OCT) with measuring of the central retinal thickness performed every three months at least. The patients treated by pegaptanib were examined every six weeks before the drug application. The fluorescence angiography (FA) was performed at the beginning of the treatment to establish the type and extension of the choroidal neovascularization and during the treatment in case of necessity to establish the activity of the choroidal neovascular membrane (CNV). The treatment by ranibizumab was in the regimen PRN (pro re nata), and pegaptanib was applied every six months during the first year with the follow-up evaluation of the findings. The treatment evaluations were performed at 12 and 24 months. RESULTS: During the two years follow - up period, the authors noticed in patients treated with ranibizumab loss of 5.12 letters of ETDRS optotypes in case of mostly classical CNV, in occult CNV loss of 5.45 letters, and in minimally classical CNV loss of 2.83 letters. In three evaluated eyes with classical CNV in patients treated with pegaptanib we noticed after 2 years loss of 6.67 letters, in eleven eyes with occult CNV we established loss of 9.91 letters, and in two eyes with minimally classical CNV the average best-corrected visual acuity (BCVA) remained unchanged. The pegaptanib treatment results may be influenced by small number of evaluated patients. The visual acuity changes during the two years treatment were not statistically significant. We noticed the decrease of average CRT (central retinal thickness) in all types of CNV treated both with ranibizumab and pegaptanib after the two years follow up. To reach these results, an average of 5.51 applications of ranibizumab and 9 applications of pegaptanib during the two years were used. CONCLUSION: In the followed-up group we found, comparing to the natural course of neovascular form of ARMD, retarding of the BCVA decrease during the two years treatment with VEGF inhibitors in everyday clinical practice. Better results were achieved with ranibizumab treatment, however the differences were not statistically significant.

RESUMO

INTRODUCTION: The age related macular degeneration (ARMD) is the most common cause of practical blindness in the population older than 60 years of age. Usually it starts as a dry form with soft drusen.The progression of the dry form is difficult to control-promising seems to be the influence of rheologic factors in the choroid and the retina and thus improvement of their blood flow. AIM: By means of haemorheopheresis to improve blood rheology and thus micocirculation in the choroid and retina. The authors describe the development of the dry form of the ARMD in the sensitive stage with soft drusen and the eventual presence of retinal pigment epithelium detachment (RPED) after haemorheopheresis. The treated patients were compared with a control group (natural course of the ARMD) with the same number of patients. METHODS: In a prospective, randomized study, comprising of 16 patients with the dry form of ARMD were treated with haemorheopheresis (cascade filtration) and 16 patients in the control group. Haemorheopheresis treatment comprised of 8 cycles in 10 weeks. Plasma obtained by separator was filtered by the Evaflux 4A (Japan) separator, where, the defined spectrum of high molecular proteins was captured. This lead to a decrease in blood and plasma viscosity and thus to improvement of rheologic conditions of the retina. RESULTS: Results show a positive influence on the absorption of soft drusen, reduction of the retinal pigment epithelium detachment, and the possibility to improve the visual acuity of the treated patients. CONCLUSION: Comparing to the worsening of clinical signs and visual functions in natural course of the ARMD development, the rheopheresis as well tolerated method may cause the retardation or stop of the unfavorable course of the disease.

RESUMO

AIM: To evaluate the efficacy of the 4 mg triamcinolone acetonide injection into the vitreous in patients with diabetic macular edema not responding to the laser treatment after one-year follow-up. PATIENTS AND METHODS: In a prospective study, 20 eyes with diffuse diabetic macular edema, not responding to the previous laser treatment were evaluated. The group consists of 20 patients; the mean age was 61.5 (29-76) years. The mean duration of diabetes was 14.5 (2-28) years. Twelve patients (60%) were treated by means of insulin, and eight patients (40%) by means of oral agents; the blood levels of glucose ranged between 3.2 - 22 mmol/L. In all patients, the treatment by means of intravitreal injection of triamcinolone started at least 3 months after the previous unsuccessful laser therapy of the macular region. Before the application, and at 1, 3, 6, 9 and 12 months after the application the visual acuity at the EDCRS optotypes was examined, the intraocular pressure was measured, the macula was examined by means of biomicroscopy, the photography of the fundus was performed by the funduscamera, and the macular thickness and its volume were measured by means of optic coherence tomography. The intravitreal injection of 4 mg of triamcinolone was performed on the outpatient's basis under aseptic circumstances at the operation theatre. RESULTS: The starting best-corrected visual acuity was 0.17 +/- 0.09 and after 12 months it improved to 0.22 +/- 0.14. During the 12 months follow-up period, the visual acuity improved in 11 eyes (55%), stabilized in 5 eyes (25%) and decreased in 4 eyes (20%). The improvement of the visual acuity was significant in all follow-up controls. In the first month p = 0.001, in the 12th month p = 0.038. The macular thickness decreased from the mean value 506.2 +/- 91.4 microm (range, 389 -719) in the beginning of the study, to the mean 362.4 +/- 92.6 microm (range, 211 - 569) after 12 months. During the follow-up period of twelve months, the macular thickness reduced in 18 eyes (90%), and increased in 2 eyes (10%). The decrease of the macular thickness is significant in all follow-up controls. In the 1st, 3rd, and 6th months, p < 0.0005, in the 9th and 12th months, p = 0.001. The correlation coefficient between the best-corrected visual acuity and the macular thickness is -0,467, and the probability (p= 0.038) is statistically significant. In 6 patients, the intravitreal injection of triamcinolone was repeated, and in one of them twice. CONCLUSION: The intravitreal injection of triamcinolone reduces the macular thickness and improves the visual acuity in patients with diabetic macular edema, in whom the laser treatment did not established the improvement. The best effectiveness is observed in the first three months after the application. After 12 months, we observed the reduction of the macular thickness in 90% of patients, and improvement of the visual acuity in 55% of patients. In some cases, it is necessary to repeat the application of triamcinolone to keep its effect.

RESUMO

The aim of this study was to evaluate the efficacy of intravitreal application of triamcinolone in macular edema of different etiology. In this prospective study, 20 eyes were evaluated: 12 with diabetic macular edema, 6 with macular edema due to venous occlusion, 1 with pseudophakic cystoid macular edema, and 1 with cystoid macular edema in case of uveitis. Four milligrams of tramcinolon acetonide were injected in to the vitreous cavity. Before and in one month intervals after the application, the intraocular pressure was measured, visual acuity on the ETDRS optotypes was established, the macula was examined biomicroscopically, examination of the photography of the fundus was performed, and macular thickness was measured by means of optical coherence tomography. The follow-up period was 3 months. The mean visual acuity was 0.16 at the beginning of the study, 1 month after the application 0.32, and after 3 months 0.31. The mean thickness of the macula decreased from the initial value 537 microm by 249 microm after one month (improvement by 46.6%) and by 203 miceom after three month (improvement by 39.7%). As a complication, the elevation of the intraocular pressure was noticed in 20% of eyes, and this was compensated in all cases by means of local therapy. The intravitreal injection of triamcinolon seems to be a promising part of treatment of the macular edema of different origin.

RESUMO

THE AIM OF THE STUDY: Authors refer to one year's results of the study of 56 eyes of 50 patients with the exsudative form of the age-related macular degeneration treated by means of transpupillary thermotherapy at the Department of Ophthalmology, School of Medicine, Charles University, Hradec Králové (Königgrätz), Czech Republic, EU. PATIENTS AND METHODS: In all patients, the best-corrected visual acuity (BCVA) before treatment was established. Beside the ordinary examination methods, the digital color photography of the fundus with topography of the lesion, fluoresceine angiography (FAG), or possibly indocyanine green angiography and optical coherence tomography (OCT) were performed. After the treatment, in given intervals, the BCVA was established, and retinal findings were evaluated by means of biomicroscopic examination, comparative color photography of the fundus, optical coherence tomography, fluoresceine angiography, or possibly indocyanine green angiography. RESULTS: During one year after the treatment, the visual acuity decreased by 2 or more lines on Snellen optotypes in 38.2% of patients, remained stable in 52.9%, and improved in 8.8% of patients. The FAG findings improved in 83.9% and the OCT findings in 84.8% of patients. This improvement was statistically significant. In patients with classical choroidal membrane, the BCVA decreased in 35.8%, remained stable in 57.1% and improved in 7.1% of patients. The FAG finding improved in 78.7%, and the OCT finding improved in 90.8% of patients. The improvement of the OCT findings was statistically significant. In patients with occult choroidal membrane, the visual acuity decreased in 45 %, remained stable in 45%, and improved in 10% of patients. The FAG findings improved in 88.9%, and the OCT findings in 78.9% of patients. The improvement was statistically significant. CONCLUSION: Our results show that transpupillary themotherapy belongs to important methods of treatment of the classical and occult membranes of the choroid in exsudative forms of the ARMD.
