Key words: ranibizumab, age-related macular degeneration, central macular thickness. Research objective. To evaluate influence of treatment with vascular endothelial growth factor inhibitor, ranibizumab, for best corrected visual acuity and central macular thickness in patients with neovascular age-related macular degeneration. Materials and methods. In this retrospective study were included treatment – naive patients. Intravitreal injections were performed at Lithuanian University of Health Sciences Kaunas Clinics Eye clinic. In this study were analysed the 24-month morphological and functional outcomes of intravitreal ranibizumab injections. Best corrected visual acuity was meassured using the Snellen chart (Landolt’s rings C optotypes). Optical coherence tomography images were obtained using the spectral – domain OCT (NIDEK RS – 3000 Advance (NIDEK CO LTD, Japan). The central thickness measurements were obtained from macular thickness maps using the digital caliper tool. Results. In this study were included 88 patients. Best corrected visual acuity before treatment was 0.36 ± 0.22. The difference between visual acuity before and after first injection was 0.04 ± 0.22 (p = 0.03). Before fifth injection visual acuity was 0.41 ± 0.21, after – 0.46 ± 0.22 (p = 0.05). Central macular thickness before treatment was 297.81 ± 106.04 μm. The difference between central macular thickness before and after first injection was 85.21 ± 113.37 μm (p < 0.001). Before second injection central macular thickness was 273.57 ± 87.49 μm, after – 234.51 ± 58.96 μm (p = 0.002). Before fourth injection central macular thickness was 237.20 ± 40.87 μm, after – 219.10 ± 42.26 μm (p = 0.04). The mean central macular thickness significantly decreased from 298.15 ± 104.78 to 229.08 ± 56.57 (p < 0.001). In 24 month of treatment the average number of ranibizumab injections was 3.61 ± 1.55. Conclusions. Our study’s results showed that over 24 month best corrected visual acuity improvement was statistically significant after first and fifth injection. Baseline compared with last injection, there was not statistically significant difference. Central macular thickness improvement statistically significant was after first, second and fourth injection. There was statistically significant decreased baseline compared with the last injection. The mean number of ranibizumab injections was 3.61 ± 1.55 in 24 month.

Purpose: To compare the effectiveness of intravitreal ranibizumab (IVR) for diabetic macular edema (DME) between eyes with and without previous vitrectomy. Procedures: We prospectively assessed the best-corrected visual acuity (BCVA) and central macular thickness (CMT) after IVR for 6 months. Results: There were no significant differences in the baseline BCVA and CMT between both groups. In the nonvitrectomized group (n = 15), the mean changes of BCVA and CMT from baseline to month 6 were significant (p < 0.01). In the vitrectomized group (n = 10), the improvement appeared to be slower, and the mean BCVA improvement was not significant (p = 0.5), although the mean CMT decrease was significant (p < 0.05). There were no significant differences in the mean changes of BCVA and CMT between both groups at 6 months. Conclusions: The difference in the effectiveness of IVR between both groups was not significant. IVR can be a treatment option even for vitrectomized DME eyes.

The purpose of the study was to evaluate changes in best corrected visual acuity, central retinal thickness, area and flow in the neovascular membrane and to compare therapeutic outcomes from baseline in patients who received three doses of Beovu (brolucizumab) at three-month follow-up. Material and methods: A prospective observational study conducted at the Prof. K. Gibiński University Clinical Center of the Medical University of Silesia in Katowice. Eight patients with exudative form of age-related macular degeneration (AMD) were observed. Results: The mean best corrected visual acuity (BCVA) outcome increased with each subsequent visit. The mean central retinal thickness (CRT) result also improved (decreased) with each subsequent visit, except for the last measurement. A statistically significant change in neovascular membrane area was observed after the first injection. In further treatment, the membrane area underwent changes that were not statistically significant. A statistically significant change in neovascular membrane flow was demonstrated after the first and second injections. Discussion: Our study confirmed the efficacy of brolucizumab in the treatment of patients with exudative AMD in terms of improvements in best corrected visual acuity (BCVA), central retinal thickness (CRT), neovascular membrane area, and neovascular membrane flow area.

Background/Aim. The integrity of outer retinal structures, primarily the photoreceptor layer, is important because of its direct correlation with visual acuity. The aim of this study was to investigate the correlation between best-corrected visual acuity (BCVA), the foveal photoreceptorinner segment/outer segment (IS/OS) junction and external limiting membrane (ELM) in patients with neovascular age-related macular degeneration (NVAMD) after the treatment with bevacizumab, as well as the correlation between the above-mentioned parameters and different types of neovascular membrane, classified by fluorescein angiography (FA). Methods. The study included 82 patients with NVAMD, treated with intravitreal bevacizumab. All patients underwent a basic ophthalmological examination, FA and optical coherence tomography (OCT). Based on the results of FA, all the patients were divided into two main groups ? type I (the occult and minimally classic) and type II (classic and predominantly classic) of the choroidal neovascular membrane (CNV). The OCT images revealed either the presence or the absence of IS/OS and ELM. Results. After the treatment, the mean best corrected visual acuity improved significantly in both groups (p < 0.01). Preserved IS/OS and ELM were registered in a smaller number of patients as compared to the condition before the treatment (p < 0.01). After the treatment, the mean BCVA was significantly better in patients with preserved IS/OS and ELM (p < 0.01). In addition, we registered a higher number of patients with preserved ELM in the first group than in the second group (p < 0.01), whereas there was no significant difference in the integrity of IS/OS between the groups (p > 0.05). Conclusion. The patients with preserved IS/OS and ELM achieved better final visual acuity as compared to the patients without preserved IS/OS and ELM. In our patients, the absence of IS/OS and ELM were more frequent in type II (classic and predominantly classic) CNV than in type I (the occult and minimally classic) CNV.

Ophthalmic Disease

Background: Taxanes are drugs used in various chemotherapeutical protocols to treat solid tumors. They have multiple systemic adverse effects, such as bone marrow suppression, alopecia, nausea, and vomiting, and may rarely cause ocular symptoms. In the past decade, a few reported cases have shown the occurrence of a cystoid macular edema with significant visual loss after the use of a taxane-based chemotherapy. The aim of this study was to compare the central macular thickness (CMT) before and after the initiation of a taxane-based therapy in visually asymptomatic patients and to elucidate the possible impact of these drugs on the vision of cancer patients. Methods: Patients with a confirmed diagnosis of a solid tumor were screened for any ophthalmic disease before inclusion and had a baseline macular spectral domain optical coherence tomography (OCT; RTVue-100; Optovue Inc., Fremont, CA, USA) before the initiation of a taxane-based chemotherapy according to different protocols, such as 4EC-4T, 3FEC/3T, or 4TC. OCT was repeated after 4 cycles (or 3 months) of treatment, and CMT was compared to baseline. Patients presenting diabetic retinopathy, age-related macular degeneration or any condition that causes macular edema confirmed by ophthalmic examination were excluded. Results: Fifty eyes of 25 patients were included; 92% of the subjects were female with a mean age of 48.52 years, 88% were diagnosed with breast cancer, 8% with esophageal cancer, and 4% with ovarian cancer. Docetaxel was the taxane administered to 92% of the patients. The received dose of docetaxel ranged between 110 and 160 mg. The other patients had paclitaxel in their protocols. No significant macular edema or drop in visual acuity were noted in any patient. Nevertheless, the mean CMT was found to be increased, particularly in the parafoveal and perifoveal areas (mean difference of +2.22 μm; p = 0.001). Conclusion: Taxane-based chemotherapy regimens seem to increase macular thickness, with a relative sparing of the fovea, in patients without significant macular edema. Further research is required to better explain the pathophysiology and possible impact of this phenomenon.

Background: Amblyopia is more common in children with high astigmatism, but factors contributing to development of amblyopia and visual outcomes are not fully understood. Objective: To evaluate the effect of amblyopia on the clinical outcomes in children with ⩾1.75 diopter (D) astigmatism. Methods: We reviewed the medical records of children with ⩾1.75 D astigmatism with and without amblyopia (amblyopes group and non-amblyopes group). The mean age, gender, amount and type of ocular deviation, presence of convergence insufficiency (CI), stereopsis, time of initial spectacle use and follow-up time, differences in best-corrected visual acuity (VoD) and spherical equivalent (SE) between eyes were assessed and compared between the groups. Best-corrected visual acuity (BCVA), mean SE, astigmatism measurements were assessed and compared between amblyopic, fellow, and non-amblyopic eyes. Results: The records included 68 eyes of 34 children with amblyopia and 56 eyes of 28 children without amblyopia. The mean age, gender, amount and type of ocular deviation, presence of CI, stereopsis, time of initial spectacle use, follow-up time, and the difference in SE did not differ between groups. In amblyopes, exodeviation was more common and statistically greater in near (33 cm) than at distance (6 m) (p = 0.005). The mean BCVA and astigmatism values were statistically different between amblyopic, fellow, and non-amblyopic eyes. Conclusion: A greater near than distance exodeviation and higher mean astigmatism value were found in amblyopic children with astigmatism.

Importance: To provide new insights into aflibercept effect in non-naive-treated patients with neovascular age-related macular degeneration. Purpose: To assess the efficacy of intravitreal aflibercept in patients with neovascular age-related macular degeneration without optimal response to previous anti-vascular endothelial growth factor A therapy. Design: Single-arm, multi-centre, prospective study. Participants: Patients ⩾50 years with active neovascular age-related macular degeneration, best-corrected visual acuity between 20/32 and 20/320 with suboptimal response to ranibizumab or bevacizumab. Methods: Aflibercept was administered monthly (3-first months), and bimonthly thereafter until month 8. Anatomical and functional outcomes were assessed. Main outcome measure: Percentage of eyes without intra or subretinal fluid on optical coherence tomography after 3-monthly loading doses of aflibercept. Results: A total of 46 patients were included. At week 12, 45.7% (95% confidence interval: 31.5%–60.1%) of eyes showed no fluid on optical coherence tomography. The mean (standard deviation) best-corrected visual acuity increased from 65.1 (8.3) to 69.6 (8.1) letters (+4.5 (5.8) p < 0.0001) and was stabilized at week 40 as compared to baseline. Mean central macular thickness decreased from 430 (119) µm to 323 (100) µm at week 12 (–107 (90) µm, p < 0.0001) and was reduced at week 40 (–46 (111) µm, p = 0.0056). At week 40, 21.7% (95% confidence interval: 9.8%–33.7%) had no fluid. There was a case of presumed noninfectious endophthalmitis that was successfully managed. Conclusion: Almost half of patients presented no fluid on optical coherence tomography at week 12, and there was a clinically significant improvement in best-corrected visual acuity. At week 40, one in five patients did not show intra or subretinal fluid, central macular thickness decreased and best-corrected visual acuity was stabilized compared to baseline.

Retinal vein occlusion is the second most common cause of blindness in retinal vascular disease after diabetic retinopathy and may lead to complications of macular edema. Bevacizumab is an influential treatment as an anti vascular endothelial growth factor (VEGF). This study aims to determine the difference of visual acuity and macular thickness before and after treatment of Bevacizumab. This is a quasi experimental study in patients with secondary macular edema retinal vein occlusion who meets the inclusion criteria. Visual acuity and macular thickness were evaluated after one month of treatment. This study was conducted for two months since May-June 2017 by collecting secondary data from medical record at SMEC Samarinda from January 2016 – June 2017. Data were analyzed using Wilcoxon. Sixteen eyes from 16 patients were diagnosed with macular edema secondary retinal vein occlusion given bevacizumab treatment. The mean visual acuity before therapy was 1.106 LogMAR ± 0.509 and increased to 0.889 logMAR ± 0.608 (p = 0.116) after treatment while the mean macular thickness before therapy was 504.06 μm ± 301.273 and decreased to 348.81 μm ± 181.17 (p = 0.017) after treatment. There was a significant effect on the decrease in macular thickness but no significant effect on visual acuity improvement in patients with macular edema secondary retinal vein occlusion at SMEC Samarinda.  Keywords: Retinal vein occlusion, macular edema, bevacizumab

Aim.Real-lifeevaluation in the management of patients affected by macular edema secondary to retinal vein occlusion.Material and Methods. A retrospective, observational study using theI-Macula Webplatform.Results. Thirty-five patients (37 eyes; 15 females and 20 male) affected by RVO were analysed. At 12 months, there was a statistically significant improvement of best-corrected visual acuity (p=0.0235) and central macular thickness (p<0.0001). The mean change in visual acuity was 8.9 letters. Twenty-seven eyes underwent DEX implant (n=62; mean: 2.29) only. Of these, 8, 4, 14, and 1 eyes underwent 1, 2, 3, and 4 DEX implants, respectively. The remaining 10 eyes were also injected with ranibizumab (n=49; mean: 4.9). At 12 months, 12 eyes (32.5%) presented a dry macula, whereas the remaining 25 eyes (67.5%) still had macular edema. Mean interval between the first and second treatment (T1) and between the second and third treatment (T2) were 5.15 and (T2) 3.7 months, respectively. Where only DEX implants were received, T1 and T2 was 5.1 and 4.9 months, respectively.Conclusions. This study confirms that DEX implants and/or anti-VEGF drugs improve visual acuity and central macular thickness in patients affected by RVO.
