Objectives: The aim of the study was comparison of wet-type age-related macular degeneration in phakic and pseudophakic patients in terms of anatomical and functional success based on the real-life data of Türkiye. Methods: The multicenter retrospective real-life study data of the. retinal study group were used in this study. Among 867 eyes of 867 patients were included in the study. Patients were divided into two groups according to the status of the lens; phakic group and pseudophakic group. The follow-up period of the two groups, the number of injections at the 1st, 2nd, and 3rd years, and changes in the central macular thickness (CMT, μ) and visual acuity (VA, logMAR) of the patients at the beginning, 6th, 12th, 24th, and 36th months were examined. Results: In our study, the number of injections in the 1st, 2nd, and 3rd years, respectively, was 4.2±2.0, 1.8±1.9, and 1.0±1.7 in the phakic group, and 3.9±2.0, 1.7±1.9, and 0.8±1.4 in the pseudophakic group. When the two groups were compared in terms of the number of injections, there was a statistically significant difference in the 1st year, but there was no significant difference in the 2nd and 3rd years (p=0.001, p=0.350, and p=0.288, respectively). There was no statistically significantdifference between the groups in terms of CMT in the baseline, 6th, 12th, 24th, and 36th months (p=0.991, p=0.327, p=0.652, p=0.599, and p=0.873, respectively). Although there was no difference in VA between groups at the beginning (p=0.052), the phakic group showed statistically better VA in controls at 3rd, 6th, 12th, 24th, and 36th months (p=0.001, p=0.001, p=0.000, p=0.000, and p=0.003, respectively). Conclusion: Differences in the number of injections and visual results between phakic and pseudophakic patients in wet type AMD may necessitate the creation of different treatment and follow-up protocols.

Objectives: This study aimed to compare the effects of dexamethasone (DEX) implants and ranibizumab (RAN) injections in younger patients with macular edema due to branch retinal vein occlusion (RVO) in a 6-month follow-up. Methods: The treatment-naive patients with macular edema secondary to branch RVO were included retrospectively. Medical records of patients who were treated with intravitreal RAN or DEX implant were evaluated before and at the 1st, 3rd, and 6th months after the injection. Primary outcome measures were the change in best-corrected visual acuity (BCVA) and central retinal thickness. The level of statistical significance was set at 0.05/3=0.016, according to the Bonferroni correction. Results: Thirty-nine eyes of 39 patients were included in the study. The mean age of the study population was 53.82±5.08 years. Median BCVA in the DEX group (n=23) at baseline, 1st, 3rd, and 6th month was 1.1, 0.80 (p=0.002), 0.70 (p=0.003), and 1 (p=0.018) logarithm of the minimum angle of resolution (log-MAR), respectively (p<0.05). Median BCVA in the RAN group (n=16) at baseline, 1st, 3rd, and 6th months was 0.90, 0.61, 0.52, and 0.46 logMAR, respectively (p<0.016 for all comparisons). Median central macular thickness (CMT) in the DEX group at baseline, 1st, 3rd, and 6th months was 515, 260, 248, and 367 μm, respectively (p<0.016 for all comparisons). Median CMT in the RAN group at baseline, 1st, 3rd, and 6th months was 432.5 (p<0.016), 275 (p<0.016), 246 (p<0.016), and 338 (p=0.148) μm. Conclusion: There is no significant difference in treatment efficacies in both visual and anatomical outcomes at the end of the 6th month. However, RAN can be considered the first choice in younger patients with macular edema secondary to branch RVO because of the lower side effect profile. [ABSTRACT FROM AUTHOR]

Purpose: To examine the effects of treatments performed on children with adenoviral conjunctivitis.Methods: 50 children with Adenoviral keratoconjunctivitis (AK) were evaluated. Patients were divided into four groups according to the medical treatment agents that were used previously. AK symptoms were clinically scored and analyzed. The diagnosis of all children was confirmed by an in-office lateral flow immunoassay.Results: Fifty patients with AK were included in the study. 24 (48%) were female and 26 (52%) were male. The mean age was 12.88 ± 2.66 (8-17). In PVP-I groups clinical findings shows faster improvement than other groups (p < .05).Conclusions: Conjunctival irrigation with 2.5% PVP-I is very effective for the treatment of adenoviral conjunctivitis in childhood. Ganciclovir ophthalmic gel 0.15% increases the effect of 2.5% PVP-I on AK, but this was not statistically significant. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To evaluate the results and recurrence rates of external and endonasal dacryocystorhinostomy (DCR) surgery in patients with primary acquired nasolacrimal duct obstruction (PANDO) in Turkish Cohort. METHODS: Medical records were reviewed in all patients who underwent surgery for PANDO between January 2010 and September 2014 in a tertiary university hospital retrospectively. The patients were followed up on the first day, first month, third month and sixth month postoperatively. Lacrimal drainage system and recurrence rates were recorded. RESULTS: This study was conducted in 81 patients, 27 of whom were men (33.3%) and 54 were women (66.7%). The mean follow-up time was 30.13±16.42 months (range 6–62 months). The mean age was 50.51±12.47 years (range 16 to 77 years). External DCR was used in 44 (66.7%) of the cases and endonasal DCR was used in 37 (45.7%) of the cases. Surgical results of DCR were divided into three groups based on the integrity and openness of the lacrimal drainage pathway in all PANDO patients. Operation success rates of these data revealed that 45 (55.6%) cases were recorded as successful, 20 (24.7%) of the cases were accepted as partially successful and 16 (19.8%) of the cases were deemed as unsuccessful. Based on these data, surgical success rates were found in 38 (86.4%) patients in external DCR and 27 (73%) patients in endonasal DCR. Surgical failure rates were six (13.6%) in external DCR and 10 (27%) in endonasal DCR. There was no statistically significant difference between success rates and recurrences in both groups (p>0.05). CONCLUSION: Endoscopic DCR produced simple, minimally invasive and preferable results compared to external DCR in the Turkish population. Although the success of external DCR is higher and the recurrence is lower than endoscopic DCR, with the outcomes of this study, endoscopic DCR can be tried as the first choice to protect the patient from major surgery and anesthesia in PANDO.

Objectives: The purpose of the study was to compare the refractive error measurements of pediatric patients performed with a Plusoptix A09 photorefractor (PO; Plusoptix AG, Nuremberg, Germany), a Retinomax K-plus 3 (RTX; Right Group, Tokyo, Japan), and the new handheld auto refracto-keratometer, the Nidek HandyRef-K (HDY; Nidek SA, Créteil, France), and to evaluate the intermethods agreement. Methods: A total of 194 eyes of 194 children were included in the study. All of the children underwent refraction measurement with the PO before cycloplegia and 2 autorefractors were used after cycloplegia: the RTX and the HDY. Results: The mean age of the patients was 16.65±10.04 months (range: 3-34 months). There were no statistically significant differences between the spherical values (SV) or cylindrical axis values (CAV) measured with the PO (SV: 1.61±1.79 diopters [D]; CAV: 94.25±72.47 D), the RTX (SV: 1.91±2.06 D; CAV: 94.3±73.44 D), and the HDY (SV: 1.89±2.04 D; CAV: 93.55±73.71 D) (p>0.05).There was a statistically significant difference in the cylindrical values (CV) assessed with the RTX (CV: -0.97±0.75 D) and the HDY (CV: -1.11±0.76 D) (p=0.003) and the HDY and the PO (CV: -0.92±0.68 D) (p=0.002), while there was no statistically significant difference between the values determined with the RTX and the PO (p>0.05). Statistically significant differences were demonstrated for spherical equivalent values (SEV) obtained with the RTX (SEV: 1.43±1.97 D) and the PO (SEV: 1.15±1.74 D) (p=0.02), and the HDY (SEV: 1.34±1.95 D) and the PO (p=0.03), but no significant difference was found between the RTX and the HDY values (p>0.05). Conclusion: No significant difference was found between the SEV measured by the RTX and the HDY, but the PO was significantly less hyperopic than the RTX and the HDY. The CV measured by HDY was higher than that of other devices. These devices can be used for screening in crowded pediatric ophthalmology clinics and may be an easier way of measuring refractive errors in children younger than 3 years of age, but high SEV and CV results should serve as an alert to physicians. It should also be kept in mind that cycloplegic retinoscopy is still the gold standard and these alternative methods can only be used for screening. The prescription of eyeglasses should not be made without cycloplegic retinoscopy. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the functional and anatomical outcomes of patients underwent combined pars plana vitrectomy (PPV) and penetrating keratoplasty (PKP) using temporary keratoprosthesis (TKP) for vitreoretinal pathology and corneal opacities secondary to severe ocular trauma. Materials and Methods: Medical records of participants that underwent combined PPV and PKP surgery with TKP for severe eye trauma were retrospectively analysed. During the follow-up, functional success (best corrected visual acuity (BCVA)) remained the same or increased, and anatomic success (retinal reattachment, graft transparency) and complications were evaluated. Results: Twenty-two eyes of 22 patients (mean age 43.40±22.43 years, 15 male/7 female) were included in this study. The mean follow-up period was 12±7.8 months. At the last follow-up, BCVA increased in 3 patients (13.6%) and remained unchanged in 16 patients (72.7%). Two of 3 patients had decreased BCVA with LogMAR chart from 2.10 to 3.10 logMAR, while 1 patient had decreased from 3.10 logMAR to loss of light sensation (13.6%). At the last follow-up, the retina was attached in 16 patients (72,8%). Corneal graft remained transparent during follow-up in 12 patients (54.5%), while graft failure was seen in 10 eyes (45.5%). Conclusion: PPV and PKP surgery combined with TKP is an alternative method for patients with corneal opacities that not allowed to vitrectomy. Although retinal reattachment is achieved in the majority of patients, corneal graft failure is a common postoperative complication. Patients should be informed about the long-term functional outcomes of this complicated surgery. [ABSTRACT FROM AUTHOR]
