Abstract
BACKGROUND Congenital simple hamartoma of the retinal pigment epithelium is often identified as an incidental finding. One important issue is the differentiation of these benign lesions from other lesions which could be potentially sight-threatening. METHODS This study describes 4 cases of congenital simple hamartoma of the retinal pigment epithelium that were referred to a university-based hospital. Multimodal imaging including fundus photo, multicolor fundus photo, fundus autofluorescence, optical coherence tomography (OCT), OCT angiography, fluorescein angiography and multifocal electroretinogram is provided. RESULTS The first case is a young man with an incidental finding of this lesion. The second and third cases are diabetic patients with congenital simple hamartoma of the retinal pigment epithelium and diabetic macular edema and the fourth one is a case of congenital simple hamartoma of the retinal pigment epithelium with a full-thickness macular hole. CONCLUSIONS Differentiation of congenital simple hamartoma of the retinal pigment epithelium from other potentially sight-threatening lesions is important. Multimodal imaging can be helpful regarding this issue. Besides typical findings described in the literature, unique features in our cases include concurrent diabetic macular edema and association with a full-thickness macular hole.

Abstract
Purpose To compare the outcomes of fluorescein angiography (FA)-guided and indocyanine green angiography (ICGA)-guided half-dose photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (CSC). Methods In this retrospective comparative study, medical records of eyes with chronic CSC who underwent half-dose PDT were reviewed. A retina specialist performed FA-guided half-dose PDT, and the other performed ICGA-guided treatment. The success of applying PDT in the resolution of subretinal fluid was compared between the FA- and ICGA-guided methods. Results Eighty-two eyes of 73 patients (41 eyes in each group) received half-dose PDT. After half-dose PDT, a significant improvement in the best-corrected visual acuity (BCVA) was found at the time of the last follow-up in both groups (both P < 0.001), with no significant intergroup difference. Central subfield and subfoveal choroidal thicknesses decreased significantly in both groups at the last follow-up (all P < 0.05), with no significant differences between the groups. Subretinal fluid (SRF) resolved in all eyes, and no persistent SRF was detected during the follow-up period. Conclusion FA-guided and ICG-guided half-dose PDT may have similar efficacy for the treatment of chronic CSC.

Abstract
Reducing intraocular pressure (IOP) with eye drops is one of the most common ways to control glaucoma. Low bioavailability and high frequency of administration in eye drops are major challenges in ocular pharmacotherapy. Contact lenses have attracted the attention of scientists in recent decades as an alternative method. In this study, with the aim of long-term drug delivery and better patient compatibility, contact lenses with surface modification and nanoparticles were used. In this study, timolol-maleate was loaded into polymeric nanoparticles made of chitosan conjugate with lauric acid and sodium alginate. Then silicon matrix was mixed with a curing agent (10:1), and the suspension of nanoparticles was added to the precursor and cured. Finally, for surface modification, the lenses were irradiated with oxygen plasma at different exposure times (30, 60, and 150 s) and soaked in different BSA concentrations (1, 3, and 5% w/v). The results showed nanoparticles with a size of 50 nm and a spherical shape were synthesized. The best surface modification of the lenses was for 5 (% w/v) albumin concentration and 150 s exposure time, which had the highest increase in hydrophilicity. Drug release from nanoparticles continued for 3 days and this amount increased to 6 days after dispersion in the modified lens matrix. The drug model and kinetic study show the Higuchi model completely supported the release profile. This study represents the novel drug delivery system to control intra-ocular pressure as a candidate platform for glaucoma treatment. Improved compatibility and drug release from the designed contact lenses would prepare new insight into the mentioned disease treatment.

Abstract
Retinoblastoma is a rare form of cancer that predominantly affects young children as the primary intraocular malignancy. Studies conducted in developed and some developing countries have revealed that early detection can successfully cure over 90% of children with retinoblastoma. An unusual white reflection in the pupil is the most common presenting symptom. Depending on the tumor size, shape, and location, medical experts may opt for different approaches and treatments, with the results varying significantly due to the high reliance on prior knowledge and experience. This study aims to present a model based on semi-supervised machine learning that will yield segmentation results comparable to those achieved by medical experts. First, the Gaussian mixture model is utilized to detect abnormalities in approximately 4200 fundus images. Due to the high computational cost of this process, the results of this approach are then used to train a cost-effective model for the same purpose. The proposed model demonstrated promising results in extracting highly detailed boundaries in fundus images. Using the Sørensen-Dice coefficient as the comparison metric for segmentation tasks, an average accuracy of 93% on evaluation data was achieved.

Abstract
This article aimed to review current literature on the safety and efficacy of stem cell therapy in Stargardt disease. A comprehensive literature search was performed, and two animal and eleven human clinical trials were retrieved. These studies utilized different kinds of stem cells, including human or mouse embryonic stem cells, mesenchymal stem cells, bone marrow mononuclear fraction, and autologous bone marrow-derived stem cells. In addition, different injection techniques including subretinal, intravitreal, and suprachoroidal space injections have been evaluated. Although stem cell therapy holds promise in improving visual function in patients with Stargardt disease, further investigation is needed to determine the long-term benefits, safety, and efficacy in determining the best delivery method and selecting the most appropriate stem cell type.

Abstract
Cystoid macular oedema (CMO), which is defined as a macular thickening and cystic changes due to accumulation of fluid, could be asymptomatic and only diagnosed using paraclinical techniques. Fluorescein angiography (FA) and optical coherence tomography (OCT) are useful in detecting CMO in clinical practice. Non-leaking CMO, also known as angiographically silent CMO, is referred to as cases of CMO without leakage in fluorescein angiography. This type of CMO has been reported in some retinal dystrophies, in cases of maculopathy as a side effect of certain drugs, and also in some systemic disorders. The exact mechanism and treatment options for this type of CMO are still not clear. This literature review aims to discuss different causes of non-leaking CMO, proposed mechanisms, and management options. Three sections including drugs, retinal dystrophies, and systemic disorders are discussed in this review.

Abstract
BACKGROUND Retinal capillary hemangioblastoma (RCH), while sporadic in some cases, is the most common and earliest manifestation of von Hippel-Lindau disease (VHL). This is the first report on different types of VHL variants and genotype-phenotype correlations in Iranian families with RCH. MATERIALS AND METHODS In this prospective observational case series study, 17 families with RCH were included. PCR was performed to amplify 3 exons of VHL gene. Afterward, Sanger sequencing was performed on all PCR products. For the detection of VHL copy number variations, MLPA was used. RESULTS Our study identified 10 different types of VHL variants. Missense mutations were the most common variants found and affected the structure of α domain of the VHL protein (pVHL). The majority of mutations (72.7%) in the patients with RCH and central nervous system hemangioblastoma (CNS-HB) were located on α domain. CONCLUSION α domain of VHL may play a potential role in the pathogenesis of RCH. Our findings suggest that genotype-phenotype characteristics in those variants in α- domain may predispose patients to RCH with CNS-HB.

Abstract
BACKGROUND/ OBJECTIVES Despite being the most common intraocular malignancy in childhood, there is a substantial disparity between developing and developed countries in terms of patient and globe survival in retinoblastoma (Rb). The current study intends to determine patient and globe survival before and after the introduction of the new targeted treatment modalities in a developing country. METHODS Medical records of 350 patients (516 eyes) with retinoblastoma referred to a tertiary referral center for Rb in Tehran, Iran, were reviewed. In order to compare patient and globe survival before and after the availability of the new treatment modalities, including intra-arterial and intravitreal chemotherapy, the patients were divided into group 1 (2001-2007) and group 2 (2008-2018) based on the calendar period of diagnosis. RESULTS Two-hundred-twenty-three eyes of 149 patients and 293 eyes of 201 patients were categorized into groups 1 and 2, respectively. The 5-year patient survival was 97% across the current survey, and the overall survival rate was 96% in group 1 and 99% in group 2 (P = 0.08). Overall, 50% of eyes with retinoblastoma underwent enucleation, which was the primary in 63% (116/184) of the unilateral and 30% (99/322) of the bilateral cases. Primary enucleation was significantly lower in group 2 (35%) in contrast to group 1 (50%) (P < 0.001). In addition, globe survival improved significantly in the International Classification of Retinoblastoma Groups D (17% in group 1 vs. 66% in group 2, P < 0.001) and E (1% in group 1 vs. 23% in group 2 P < 0.001) during the two timelines. In enucleated eyes, despite the increased rate of prelaminar involvement in group 2 (13% vs. 2% in group 1, P = 0.003), the rate of high-risk histopathologic findings was similar between the two groups. CONCLUSION Similar to developed countries, the application of new targeted treatment modalities, including intra-arterial and intravitreal chemotherapy, has been associated with significantly improved globe survival in Rb patients. However, it should be noted that even with the availability of these novel treatment options, the decision for on-time enucleation should not be deferred.

Abstract
As the most common primary intraocular malignancy of childhood, retinoblastoma (RB) has had a complex journey in its management, following a course from enucleation as the first life-saving treatment to numerous globe-salvaging therapies during the last century. Currently, this potentially lethal disease has achieved high survival rates owing to multidisciplinary management and the introduction of neoadjuvant and multimodal chemotherapy. Therefore, the goal of treatment is shifting toward conserving the globe and vision as much as possible. Up until recently, many advanced cases of RB were enucleated primarily; however, targeted chemotherapy via the ophthalmic artery and management of intraocular seeding by local administration of chemotherapeutic agents have revolutionized the globe-conserving therapies. The added benefit of avoiding systemic complications of cytotoxic drugs resulted in these methods gaining popularity, and they are becoming a main part of care in many referral centers. Initially, there were some safety concerns regarding these approaches; however, increasing experience has shown that these modalities are relatively safe procedures and many complications can be averted by changing the choice of the drug and using some prophylactic measures. It is hoped that, in the near future, with advances in early diagnosis and patient-targeted molecular therapies, as well as gene-editing techniques, the patient's vision can be saved even in advanced RB.

Abstract
Purpose To investigate the association of polymorphisms (rs9568036 and rs1801270) in the RB1 and P21 genes with susceptibility to retinoblastoma (RB). Methods This case-control study was designed with 50 patients with RB and 50 controls. Polymerase chain reaction was performed to amplify the intron 17 of RB1 rs9568036 and exon 2 of P21 rs1801270. Then, all the amplified fragments were subjected to directional sequencing, and finally, the association between genotypes and the development of RB risk and invasion was studied. Results A statistically significant difference in genotypic or allele frequencies of single-nucleotide polymorphisms (SNPs) (rs1801270 and rs9568036) was found between Iranian RB patients and the controls (P > 0.05). However, the frequency of genotype RB1 rs9568036 observed a statically significant difference in the RB patients compared to the control group, and the nonwild-type allele A increased the chance of susceptibility to developing RB by 2.92 times. Conclusion The rs9568036 SNP in the RB1 gene may increase susceptibility to the development of RB in the affected patients. In spite of that, this polymorphism does not influence RB patient's invasion. Further investigation with a large enough sample size is recommended to validate this hypothesis.

Abstract
Background To report the long-term outcomes of Ru-106 plaque radiotherapy in eyes with uveal melanoma (UM) and to assess the effect of tumor thickness and location on final outcomes. Methods Medical records of 234 patients undergoing Ru-106 plaque radiotherapy for UM were reviewed, and the visual outcome, globe preservation, and patient survival were evaluated. The results of 2 groups were compared: 1. between thin (small and medium-sized, thickness < 7 mm, 148 eyes [63.2%]) and thick (thickness ≥ 7 mm, 86 eyes [36.8%]) tumors, and 2. between large (largest basal diameter [LBD] > 12 mm, 109 eyes [46.6%]) and medium/small (LBD ≤ 12 mm, 125 eyes [53.4%]). In addition, a comparison of the juxtapapillary location in 46 eyes (19.7%) versus tumors arising elsewhere and between tumors with and without ciliary involvement in 48 eyes (21.5%) were done. Results The patients were followed for a median of 54.2 months (range: 6–194.5 months). After adjusting for baseline visual acuity (VA), there was no significant association between final VA and different dimension and tumor location groups. Final globe preservation was 91.9%, and there was no significant difference between different dimension- and ciliary body involvement groups regarding anatomical success rate. The juxtapapillary tumors had lower globe preservation (80.4% vs .94.7%, p = 0.002). The hazard ratio (HR) for enucleation in juxtapapillary tumors was HR = 6.58 (95-CI: 3.84 to 11.21). The overall metastasis rate was 6.8%, with no significant difference in juxtapapillary tumors (4.3% vs.7.4%, p = 0.455). Conclusions Ru-106 plaque radiotherapy is an effective treatment for thick and large UM. With this type of treatment, the globe preservation rate is lower in juxtapapillary tumors, but there is no significant difference in the metastasis rate.

Abstract
Retinoblastoma (Rb) is a rare childhood intraocular malignancy with an incidence rate of approximately 9000 children per year worldwide. The management of Rb is inherently complex and depends on several factors. The orders of priorities in the treatment of Rb are saving life, globe salvage and vision salvage. Rarity and the young age at diagnosis impede conducting randomized clinical trials (RCTs) for new therapeutic options, and therefore pre-RCTs studies are needed. This review provides an overview of advances in Rb treatment options, focusing on the emergence of new small molecules to treat Rb. Articles related to the management and treatments of Rb were searched in different databases. Several studies and animal models discussing recent advances in the treatment of Rb were included to have a better grasp of the biological mechanisms of Rb. Over the years, the principles of management and treatment of Rb have changed significantly. Innovations in targeted therapies and molecular biology have led to improved patient and ocular survival. However, there is still a need for further evaluation of the long-term effects of these new treatments.

Abstract
Retinal pigment epithelium (RPE) degeneration is the hallmark of age-related macular degeneration (AMD). AMD, as one of the most common causes of irreversible visual impairment worldwide, remains in need of an appropriate approach to restore retinal function. Wet AMD, which is characterized by neovascular formation, can be stabilized by currently available therapies, including laser photocoagulation, photodynamic therapy, and intraocular injections of anti-VEFG (anti-vascular endothelial growth factor) therapy or a combination of these modalities. Unlike wet AMD, there is no effective therapy for progressive dry (non-neovascular) AMD. However, stem cell-based therapies, a part of regenerative medicine, have shown promising results for retinal degenerative diseases such as AMD. The goal of RPE cell therapy is to return the normal structure and function of the retina by re-establishing its interaction with photoreceptors, which is essential to vision. Considering the limited source of naturally occurring RPE cells, recent progress in stem cell research has allowed the generation of RPE cells from human pluripotent cells, both embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSC). Since iPSCs face neither ethical arguments nor significant immunological considerations when compared to ESCs, they open a new horizon for cell therapy of AMD. The current study aims to discuss AMD, review the protocols for making human iPSCs-derived RPEs, and summarize recent developments in the field of iPSC-derived RPEs cell therapy.

Abstract
Purpose: Plaque therapy is a well-recognized treatment for intraocular tumors. In current study, we aimed to prospectively investigate the short-term effects of ruthenium 106 (Ru-106) plaque therapy on the cornea and ocular surface parameters. Methods: Twenty-five patients diagnosed with choroidal melanoma which undergone Ru-106 plaque therapy from 2016 to 2018 were included. Tear osmolarity, tear film break-up time, Schirmer test I, fluorescein dye staining based on Oxford staining method; Ocular Surface Disease Index (OSDI) questionnaire and corneal specular microscopy were performed. These tests were assessed preoperatively and then 3 months postoperatively. Results: The mean (±SD) age of subjects was 48.52 ± 15.18 years. The patients were followed for a mean(±SD) period of 3.64 ± 2.40 months. Total mean (+SD) delivered radiation dose to the tumor apex and total received radiation by the sclera was 83.20 ± 26.31 and 640.65 ± 472.69 Gray (Gy), respectively. In longitudinal analysis, OSDI score and Oxford staining score increased significantly (P = 0.002 for both variables) and the prevalence of dry eye disease (DED) increased from 20% preoperatively to 72% at 3 months postoperatively (P = 0.001).The changes in the all specular microscopy parameters were statistically nonsignificant (all P values > 0.05). Conclusion: There is a considerable increase in the rate of DED following plaque therapy for the treatment of choroidal melanoma in short-term follow-up. The OSDI questionnaire and fluorescein staining test are valuable tools for early detection of DED postoperatively.

Abstract
Background: To investigate the effect of various factors on ocular motility disturbance after episcleral plaque brachytherapy with Ruthenium 106 (106Ru).Methods: Twenty consecutive patients who underwent plaque brachytherapy for all types of intraocular tumors were included in this interventional prospective case series. Ruthenium-106 was used with a mean total dose of 93.2 ± 21.2 Gy toward the tumor apex. Full orthoptic examinations were performed before and after the surgery.Results: The average follow-up time was 6 months (range: 4-9 months). Two (10%) out of 20 patients developed exotropia. The mean age of patients without strabismus was higher than the patients with strabismus (49.8 ± 10.7 years compared to 23 ± 4.2 years, respectively) (p = .011). Strabismus was observed in the patients who had tumors with larger apical diameters (7.6 ± 2 mm compared to 4.1 ± 0.9 mm, respectively) (p = .021). The mean radiation dose to the tumor base in the group with strabismus was higher than the group without motility disturbance (1046.5 ± 604.1 Gy compared to 384.3 ± 175.3, respectively) (p = .021). Most tumors were located in the inferotemporal fundus (30%), followed by supratemporal location (25%), supranasal (10%), and macular region (10%). A higher percentage of patients with postoperative strabismus underwent muscle manipulation compared to the patients who did not develop this complication (100% compared to 38.9%).Conclusion: Manipulation of the extraocular muscles, high doses of radiation, and low vision could cause strabismus after episcleral plaque brachytherapy.

Abstract
The purpose of this study was to introduce a new deep learning (DL) model for segmentation of the fovea avascular zone (FAZ) in en face optical coherence tomography angiography (OCTA) and compare the results with those of the device’s built-in software and manual measurements in healthy subjects and diabetic patients. In this retrospective study, FAZ borders were delineated in the inner retinal slab of 3 × 3 enface OCTA images of 131 eyes of 88 diabetic patients and 32 eyes of 18 healthy subjects. To train a deep convolutional neural network (CNN) model, 126 enface OCTA images (104 eyes with diabetic retinopathy and 22 normal eyes) were used as training/validation dataset. Then, the accuracy of the model was evaluated using a dataset consisting of OCTA images of 10 normal eyes and 27 eyes with diabetic retinopathy. The CNN model was based on Detectron2, an open-source modular object detection library. In addition, automated FAZ measurements were conducted using the device’s built-in commercial software, and manual FAZ delineation was performed using ImageJ software. Bland–Altman analysis was used to show 95% limit of agreement (95% LoA) between different methods. The mean dice similarity coefficient of the DL model was 0.94 ± 0.04 in the testing dataset. There was excellent agreement between automated, DL model and manual measurements of FAZ in healthy subjects (95% LoA of − 0.005 to 0.026 mm2 between automated and manual measurement and 0.000 to 0.009 mm2 between DL and manual FAZ area). In diabetic eyes, the agreement between DL and manual measurements was excellent (95% LoA of − 0.063 to 0.095), however, there was a poor agreement between the automated and manual method (95% LoA of − 0.186 to 0.331). The presence of diabetic macular edema and intraretinal cysts at the fovea were associated with erroneous FAZ measurements by the device’s built-in software. In conclusion, the DL model showed an excellent accuracy in detection of FAZ border in enfaces OCTA images of both diabetic patients and healthy subjects. The DL and manual measurements outperformed the automated measurements of the built-in software.

Abstract
Objective:
The present study was designed to evaluate the effects of Atorvastatin (ATO)
plus Melatonin (MEL) on streptozocin-induced Diabetic Retinopathy (DR) in rats.
Methods:
Diabetes was induced in Wistar rats with an intraperitoneal injection of streptozocin
(50 mg/kg). Animals were randomly assigned to one of the following groups (8 rats/group): Control
group, Diabetic group, Diabetic + MEL group (20 mg/kg/day), Diabetic + ATO group (10
mg/kg/day), Diabetic + MEL + ATO group (as above). Treatments were started one week after
induction of diabetes and continued for 7 weeks. At the end of the experiment, angiography was
performed and the rats were killed and retinas were harvested for pathological and molecular examinations.
Results:
Administration of MEL reduced the fluorescein leakage, MDA and ROS levels compared
to diabetic group. Treatment with ATO only reduced ROS levels compared to diabetic group. In
addition, administration of ATO plus MEL decreased these indices compared to the diabetic and
ATO groups. Histologically, retinal vascular congestion was not observed in the combined ATO
and MEL group as compared to the diabetic, ATO, and MEL groups.
Conclusion:
These data provide evidence for the therapeutic value of MEL in combination with
ATO in clinical practice for prevention of DR.

Abstract
Optical coherence tomography angiography (OCTA) is a revolutionary method in the visualization of the vascular system in different retinal and choroidal layers. During the last 4 years since the commercial availability of different OCTA devices, attempts have been made to utilize this technology in various aspects of ocular oncology from the differentiation of benign and malignant lesions to assisting in evaluation of post-treatment complications, such as radiation retinopathy. However, current OCTA technology is restricted by various artefacts and inherent limitations, some of which are more pronounced in the presence of elevated tumoural lesions. Imminent advancements in OCTA systems and image acquisition processes promise a great potential for application of OCTA in ocular oncology.

Abstract
Purpose: To report the clinical outcome of rhuthenium-106 plaque radiotherapy in acquired retinal pigment epithelial (RPE) tumors. Methods: In this interventional case series, two eyes of two patients with clinically diagnosed ocular-acquired RPE tumors including adenoma and adenocarcinoma underwent plaque radiotherapy with rhuthenium-106. The clinical findings and visual outcome of the patients were evaluated. Results: The first patient was a 44-year-old male, and the second was a 32-year-old female. The follow-up times were 24 and 32 months. The tumor was unilateral and hyperpigmented in both cases, located at juxtapapillary in one patient and on peripheral part of the retina in the other. Vitreous hemorrhage and peripheral exudation were obvious in one patient. Macular edema, epiretinal membrane, and retinal feeder vessels were also detected in the examination. The patients underwent plaque radiotherapy with rhuthenium-106 as the first step of management. The tumor has been stable until the last follow-up in both patients with globe preservation and acceptable visual acuity (5/10 for the first case and 4/10 for the second case). Conclusion: Rhuthenium-106 plaque radiotherapy might be a conservative therapy in the management of acquired RPE tumors and prevent early enucleation.

Abstract
Optic neuropathies refer to the dysfunction or degeneration of optic nerve fibers caused by any reasons including ischemia, inflammation, trauma, tumor, mitochondrial dysfunction, toxins, nutritional deficiency, inheritance, etc. Post-mitotic CNS neurons, including retinal ganglion cells (RGCs) intrinsically have a limited capacity for axon growth after either trauma or disease, leading to irreversible vision loss. In recent years, an increasing number of laboratory evidence has evaluated optic nerve injuries, focusing on molecular signaling pathways involved in RGC death. Trophic factor deprivation (TFD), inflammation, oxidative stress, mitochondrial dysfunction, glutamate-induced excitotoxicity, ischemia, hypoxia, etc. have been recognized as important molecular mechanisms leading to RGC apoptosis. Understanding these obstacles provides a better view to find out new strategies against retinal cell damage. Melatonin, as a wide-spectrum antioxidant and powerful freeradical scavenger, has the ability to protect RGCs or other cells against a variety of deleterious conditions such as oxidative/nitrosative stress, hypoxia/ischemia, inflammatory processes, and apoptosis. In this review, we primarily highlight the molecular regenerative and degenerative mechanisms involved in RGC survival/death and then summarize the possible protective effects of melatonin in the process of RGC death in some ocular diseases including optic neuropathies. Based on the information provided in this review, melatonin may act as a promising agent to reduce RGC death in various retinal pathologic conditions.

Abstract
PURPOSE This study evaluates the outcomes of ruthenium-106 (Ru-106) plaque brachytherapy for vasoproliferative tumors (VPTs) of the ocular fundus in a single referral ocular oncology center. METHODS The clinical charts of all patients diagnosed with VPT who underwent plaque radiotherapy from 2002 to 2017 were reviewed. Clinical features, types of treatment, outcomes and complications were evaluated. RESULTS Of 46 patients with VPT diagnosis in our ocular oncology clinic, 25 (54.34%) cases were treated with Ru-106 plaque brachytherapy. Eleven patients (44%) were male, and the mean age at the time of diagnosis was 40.92 ± 13.11 years. The mean follow-up time was 47.56 ± 36.87 months. Inferotemporal quadrant was the most common site of the tumor (64.00%). The mean delivered apex and scleral dose was 101.56 ± 6.51 and 412.26 ± 113.66 Gray (Gy), respectively. Initial tumor length, width and thickness were 10.26 ± 3.42, 8.05 ± 2.83 and 4.27 ± 1.10 mm, respectively. The mean tumor thickness decreased to 2.60 ± 0.63 mm, postoperatively. Complete resolution of subretinal fluid around the tumor was achieved in 81.80% of cases. Visual acuity was more than 20/400 in 64% of patients before treatment and 60% of patients at last follow-up. CONCLUSION Our study showed that Ru-106 plaque radiotherapy is an effective and safe method of treatment in VPTs.

Abstract
Retinoblastoma tumor (RB) is one of the most prevalent ocular cancers among children. RB may be caused by inherited mutations in RB1 gene as well as some environmental risk factors. Human papillomaviruses (HPV) are suspected as a risk factor of RB due to their pRb inactivating protein. This study evaluated the molecular prevalence of HPV among the RB tumor specimens in Iran. The RB tumor samples were tested for detection of HPV-L1 gene using a nested-PCR approach, and then followed by sequencing and phylogenetic analysis to reveal HPV types. Overall, there were 61 RB tumor samples; 54/61 (88.5%) had unilateral and 7/61 (11.5%) bilateral RB; 55/61 cases (90.2%) had sporadic non-familial RB tumor. HPV-DNA was detected in 6/61 (9.8%) of patients' tumors; the HPV positive RB cases all had unilateral and unfamiliar sporadic RB tumor. HPV type 16 was the most prevalent type identified across the RB tumor samples (3/61, 4.9%). The rate of detected HPV among the RB specimens seems to be considerable. Further investigations are required to elucidate the exact association between HPV and progression to RB.

Abstract
Purpose: To evaluate the role of intrasilicone oil injection of methotrexate (MTX) at the end of vitrectomy surgery for rhegmatogenous retinal detachment (RRD) associated with proliferative vitreoretinopathy (PVR).Methods: In this prospective comparative study, pars plana vitrectomy and retinal reattachment were performed for eyes with RRD with grade C PVR. In the MTX group, 250 µg MTX was injected into the silicone oil at the end of surgery. The rate of retinal redetachment associated with PVR was assessed.Results: In total, 44 eyes of 44 patients (22 in the MTX group and 22 controls) were included. Baseline characteristics were similar between the two groups. Retinal redetachment occurred in one eye (4.5%) in the MTX group and five eyes (22.7%) in the control group (p = 0.18). The change in visual acuity was similar between the two groups at final visit (p = 0.15).Conclusion: The rate of redetachment associated with PVR was lower after intrasilicone injection of MTX at the end of vitrectomy for RRD with severe PVR compared to control group; however, the difference was not statistically significant.

Abstract
PurposeTo present our experience with the surgery in retinal detachment (RD) associated with giant retinal tear (GRT) over 10 years in a tertiary referral hospital.Patients and MethodsIn this retrospective study, the charts of all patients with the diagnosis of RD associated with GRT who underwent surgery from 2005 to 2015 at Rassoul Akram Hospital were reviewed. Exclusion criteria were concomitant presence of diabetic retinopathy, and uveitis. All patients had to have at least 3 months of follow up. The success rate and factors associated with repeated surgery were determined.ResultsSixty two eyes of 61 patients including 51 males and 10 females were assessed. Proliferative vitreoretinopathy (PVR) was present in 14 (22.6%) of eyes. Pars plana vitrectomy (PPV) alone was performed in 44 eye (71.0%) and simultaneous vitrectomy and phacoemulsification surgery was performed in 18 eyes (29.0%). An encircling episcleral band was placed in 7 eyes (11.3%). Anatomic success after one vitrectomy procedure was achieved in 45 eyes (72.58%) and ultimately in 61 eyes (98.4%) at last follow up. Seventeen eyes needed repeated PPV due to redetachment associated with PVR in the follow up period. The rate of repeated PPV was significantly higher in eyes with PVR at baseline and surgery with encircling episcleral band. Trauma, extension of tear, age, and lens status had no significant effect on the rate of repeated PPV.ConclusionsOur study shows that the high surgical success can be achieved in patients with RD associated with GRT with single or multiple surgeries.

Abstract
OBJECTIVE We assessed the effectiveness of educational interventions in increasing the perceived risk of fireworks and preventing fireworks-related injuries among male teenagers. METHODS In a field trial, using a cluster sampling approach, 3 high-, middle- and low-income municipality districts were selected. In each district, 5 male middle and high schools were randomly selected and assigned into one control and 4 intervention groups: (1) distribution of a multimedia disk regarding injury victims; (2) distribution of safety brochures; (3) mailing to parents from schools discussing the risk of fireworks and limiting the fireworks budget; and (4) peer-to-peer education by trained students about the risks of fireworks. Safety instructions were included in all interventions. RESULTS After analyzing 1584 students' responses, the use of firecracker inversely correlated with the economic level of families (p < .001). The risk factors for fireworks-related injury (N = 31, 2.0%) included use of hazardous fireworks, making bonfires, history of fireworks-related injury, fireworks budget, and "willingness to pay." Preventive interventions did not statistically change the use of fireworks, fireworks budget, making a bonfire, and fireworks-related injuries compared with the preceding year. The interest in hazardous fire crackers was less in intervention group; however, no statistically significant differences among the different interventions were observed. CONCLUSION The interventions failed to lessen risky behaviors and fireworks-related injuries among male teenagers.

Abstract
PurposeThe most common intraocular tumor in childhood, retinoblastoma, is largely associated with mutations in the RB1 gene. In the most comprehensive RB1 screening in Iran, we evaluated the RB1 mutations in 106 patients with retinoblastoma, including 73 bilateral (heritable) and 33 unilateral (sporadic) cases.Patients and methodsMutations were identified using amplification refractory mutation system (ARMS) PCR and direct sequencing of the 27 coding exons of RB1 and multiplex ligation-dependent probe amplification (MLPA).Results and ConclusionWe found 33 (31%) and 64 (60%) patients with sporadic unilateral and bilateral retinoblastoma, respectively as well as 9 (8.5%) cases with hereditary bilateral retinoblastoma. In total, we identified 52 causative RB1 mutations in 106 patients (global mutation rate of 49%). Of the 52 patients, 48 (92%) had sporadic and familial bilateral and 4 (8%) had sporadic unilateral RB. Therefore, the detection rate of RB1 mutations was 66% (48/73) and 12% (4/33) in bilateral and unilateral cases, respectively. Mutations were classified as nonsense in 31 (60%), missense in 1 (2%), large deletion in 11 (21%), small deletion in the 7 novel (15%) and splice site mutation in 2 (4%) patients with RB. Of 31 nonsense mutations, 23 (74%) occurred in the 11 Arginine codons of the RB1. Seven mutations (13%) were novel, and 45 (87%) had been previously reported. Thirty-three mutations were single-base substitutions leading to 31 nonsense amino acid changes and 2 splice site mutations in introns 12 and 16 of RB1. The altered 3D model structures of the RB1 novel mutant proteins are also predicted in this study.

Abstract
Purpose: To report the outcomes of half-dose photodynamic therapy (PDT) in patients with chronic central serous chorioretinopathy (CSC). Methods: A chart review of patients with chronic CSC who had received half-dose verteporfin PDT (3 mg/m2) was performed. The main outcome measures were resolution of subretinal fluid and best corrected visual acuity (BCVA). Results: Fifty-three eyes of 51 patients with mean age of 45.01 ± 8.9 years were studied. Three, 6 and 12 months after half-dose PDT, subretinal fluid was completely resolved in 51 eyes (96.2%). In 2 eyes (one patient), subretinal fluid decreased at 3 months but one year later, an increase in subretinal fluid was detected on optical coherence tomography (OCT) which completely resolved following additional PDT. Another patient with recurrence of subretinal fluid rejected further treatment. Mean baseline central subfield thickness was 385 ± 113.0 μm which was decreased to 235 ± 39.7, 247 ± 49.7, and 244 ± 49.52 μm after 3, 6 and 12 months, respectively (all P-values < 0.001). Mean BCVA was 0.33 ± 0.27 LogMAR before PDT and 0.11 ± 0.18, 0.11 ± 0.17, 0.17 ± 0.26 and 0.10 ± 0.23 LogMAR, 3, 6 and 12 months and at final visit (up to 60 months) after PDT, respectively (all P-values < 0.001). Improvement ≥2 lines in BCVA occurred in 20 eyes (37.7%). Statistically significant correlations were found between improvement in BCVA and baseline BCVA, baseline central subfield thickness and central subfield thickness after resorption of subretinal fluid (P < 0.001, P= 0.04 and P= 0.01, respectively). No complications attributed to PDT were observed. Conclusion: Half-dose PDT is effective for treatment of patients with chronic CSC.

Abstract
Purpose The aim of this study was to investigate the rate of monosomy 3 by CISH technique in Iranian patients with uveal melanoma (UM) and its correlation with clinical and histopathological features. Method Archival formalin fixed, paraffin-embedded material from 50 patients who had undergone enucleation for large uveal melanomas was obtained. Monosomy of chromosome 3 alteration by chromogenic in situ hybridization (CISH) was investigated. Clinical and histopathological features of tumors were collected. Results The patients had a mean age of 56.6±7.6 years. Mean basal diameter and thickness of tumors were 14.1 mm and 10.2 mm, respectively. Four patients (8%) were identified to harbor monosomy of chromosome 3. In the mean follow-up of 5.3 years (range, 3.2–9.5 y), only one case with monosomy 3 died of UM metastasis. The most common type of cellularity was mixed cell (86%). There was not any statistically significant correlation between monosomy of chromosome 3 and type of cellularity, ciliary body involvement, and largest basal diameter. Conclusion The low rate of monosomy chromosome 3 and the consequent low rate of mortality may be indicative of good prognosis in Iranian patients with uveal melanoma.

Abstract
Purpose To report a case of perfluorocarbon liquid (PFCL) migration into the subarachnoid space at the time of vitreoretinal surgery in a patient with morning glory syndrome associated retinal detachment. Case report A 9-year-old girl underwent pars plana vitrectomy and silicone oil injection for retinal detachment associated with morning glory syndrome. PFCL was used for retinal stabilization before endolaser photocoagulation. The retina detached, and repeated vitrectomy and silicone oil injection was performed. Postoperative magnetic resonance imaging revealed PFCL in the subarachnoid space. Conclusion The migration of perfluorocarbon into the subarachnoid space is a rare complication of vitrectomy in patients with morning glory syndrome.

Abstract
PURPOSE To evaluate the outcome of scleral buckling surgery in patients with rhegmatogenous retinal detachment (RRD) with subretinal proliferation. METHODS In this retrospective study, a chart review of all patients with RRD associated with subretinal proliferation who were primarily treated with scleral buckling procedure, from April 2007 to April 2014, was undertaken. Main outcome measures were anatomical retinal reattachment and visual acuity. RESULTS Forty-four eyes of 43 patients including 24 males and 19 females with a mean age of 26.5±13.1 years were evaluated. Immediately after the surgery, retina was reattached in all eyes. However, five eyes (11.3%) needed additional surgery for retinal redetachment. Single surgery anatomical success rate was 88.7%. Four eyes (9.1%), needed pars plana vitrectomy for the treatment of redetachment associated with proliferative vitreoretinopathy and scleral buckle revision surgery was successfully performed in the other eye. Best corrected visual acuity improved from 1.5±0.9 logMAR before surgery to 1.1±0.7 logMAR after surgery (P<0.001). An improvement in BCVA of >2 lines was found in 23 eyes (52.2%) and worsening of best corrected visual acuity of >2 lines was observed in 2 eyes (4.5%). CONCLUSIONS Scleral buckling surgery is highly successful in eyes with RRD associated with subretinal proliferation.

Abstract
AIM To assess main indications, postoperative complications and clinicopathological correlation of ocular enucleation-evisceration. METHODS A total of 107 subjects who underwent enucleation and/or evisceration and received hydroxyapatite implants (Scleral wrap or mesh) were assessed. For each patient clinicopathological data was collected which included demographic information, clinical history, primary clinical diagnosis, main cause of ophthalmic surgery (traumatic, non-traumatic), type of surgical procedure (enucleation, evisceration) and pathological report. Patients' postoperative clinical visits were checked for procedure-related complications during first year after surgery. RESULTS ONE HUNDRED AND SEVEN PATIENTS (MALE: 65.4%; mean age: 26y) underwent enucleation (n=100) or evisceration (n=7) due to traumatic (n=41) and non-traumatic (n=66) causes. Disfiguring painful blind eye was the most common indication of surgery (66.4%), followed by leukocoria (19.6%) and endophthalmitis (4.7%). The main types of injury included firecracker, traffic and work accidents, and sharp object perforating injury. In 53 (80.3%) subjects in non-traumatic group the initial clinical diagnosis matched the histopathological results. Malignant tumors (retinoblastoma: 47.5%, malignant melanoma: 27.3%) were the most common pathological diagnoses followed by phthisis bulbi (25.8%). The most common procedure-related complications were major eye discharge (39.6%), and implant exposure and discharge (20.8%). CONCLUSION Trauma and malignant tumors are the leading causes of enucleation-evisceration. Despite developing new techniques and materials, enucleation is still associated with considerable postoperative complications.

Abstract
PURPOSE To evaluate the visual and anatomic results and determine the prognostic factors after pars plana vitrectomy and posterior segment intraocular foreign body (IOFB) removal. MATERIALS AND METHODS This retrospective study reviews the patients' charts of 48 consecutive patients with posterior segment IOFB who underwent pars plana vitrectomy and IOFB removal over a 4-year period, recently. Association between visual outcome and various preoperative, operative, and postoperative variables was statistically analyzed. Data were analyzed with the paired t-test and the chi square test. Statistical significance was indicated by P < 0.05. RESULTS The mean interval between the time of injury and IOFB removal was 24 ± 43.1 days and 27 (53%) eyes underwent IOFB removal within 7 days of the injury. Nine (19.1%) patients achieved a visual acuity of 20/40 or better. An improvement of visual acuity of at least three lines occurred in 21 (44.6%) eyes and the vision remained unchanged in 15 (31.9%) eyes. Postoperative retinal detachment occurred in five (10.6%) eyes. Visual improvement was more likely to occur in eyes with lower levels of presenting visual acuity (P = 0.2). Visual improvement was not associated with an entry site and IOFB location, lens injury, time to surgery, and pre- and post-operative retinal detachment. At the end of follow up, anatomical success was achieved in 97.9% of eyes. CONCLUSIONS High anatomical success could be achieved after the removal of posterior segment IOFBs by vitrectomy, despite a delay in surgery. Poor visual outcome may be mainly due to the initial ocular injury.

Abstract
PURPOSE To screen deletions/duplications of the RB1 gene in a large cohort of Iranian patients using the multiplex ligation-dependent probe amplification (MLPA) technique. METHODS A total of 121 patients with retinoblastoma, involving 55 unilateral and 66 bilateral or familial retinoblastomas, were included in this study. Among these patients, 121 blood and 43 tissue samples were available. DNA was extracted from the blood and tissue samples and analyzed with an RB1-specific MLPA probe set. The mutation findings were validated with SYBR Green Real-Time PCR. RESULTS Twenty-two mutations were found in 21 patients; of these, ten mutations were detected in patients with isolated unilateral retinoblastoma. CONCLUSIONS Our results suggested that MLPA is a fast, reliable, and powerful method for detecting deletions/duplications in patients with retinoblastoma.

Abstract
The patients' survival for the most common intraocular tumor in children, retinoblastoma, has a wide spectrum among the world countries. This study was conducted to provide an overview of the retinoblastoma survival disparity worldwide by discussing the trends of patients' survival, as well as recent advances in the management of retinoblastoma. The design of this study was literature review and commentary. Selected articles from PubMed (except one) including both developing and developed countries regarding the patients' survival in retinoblastoma were considered and reviewed critically. An analysis of 47 articles was performed. In conclusion, in spite of an obvious contrast of retinoblastoma survival disparity in the world, the expanding horizons in developing countries are promising and continuing on all fronts and results are hope-inspiring.

Abstract
BACKGROUND: To evaluate the efficacy of surgical excision, cryotherapy and topical Mitomycin C (MMC) for ocular surface squamous cell carcinoma (SCC) with at least 24 months follow-up. METHODS: Seventeen patients with primary and recurrent invasive SCC of ocular surface underwent surgical excision and map biopsy of the margins, and double freeze-thaw cryotherapy of the bed and margins. Topical MMC (0.04%, 4 times daily) was commenced 7-10 days after operation. It was delivered in cycles that consisted of medication 4 times daily for 7 consecutive days followed by 7 consecutive days of no medication. Patients with primary SCC received two cycles (protocol 1) and those with recurrent SCC received three cycles (protocol 2). Patients with intra-ocular and or orbital extension or those with less than 24 months of follow-up were excluded. The frequency of tumor recurrence and complications associated with treatment were measured. RESULTS: Mean age was 70.7 years (SD = 10, range: 48-80). Mean follow-up time was 48 months (SD = 21, range: 24-89). There were 12 patients with primary SCC and five with recurrent SCC. Mean largest diameter was 9.7 mm (3-20). Surgical margins were free in 12 cases. One patient with recurrent SCC who received protocol 2 treatment developed recurrence 9 months after excision, and remained free of recurrence 24 months after second treatment. Complications comprised transient mild punctate corneal epithelial erosion (eight), irritation and conjunctival hyperemia (11), corneal scar (six), and scleral thinning (three). All except one responded well to conservative management. One scleral thinning required scleral patch graft 1 year after treatment. CONCLUSION: The combination of surgical excision, cryotherapy, and post-operative topical mitomycin-C was effective treatment for ocular surface invasive SCC in long-term follow-up.

Abstract
INTRODUCTION Fireworks are used worldwide as a part of national and cultural celebrations. Personal use of fireworks is associated with serious injuries. The "Last Wednesday Eve Festival" is celebrated on the evening before the last wednesday of the Persian calendar year. In recent years, fireworks have been widely used during the festival, which has resulted in injuries. The aim of this study was to determine the incidence and risk factors of fireworks-related injuries associated with the Last Wednesday Eve Festival, in Tehran, Iran. METHODS A household survey of residents of greater Tehran, using a random cluster sampling design was performed. Number of fireworks-related injuries, expenditures for fireworks and medical treatment of fireworks-related injuries, length of hospital stay for treatment of these injuries and the personal property damage was gathered. RESULTS Interviews were conducted of 2475 households in greater Tehran. At least one member of 19.8% of these households had used fireworks during the 2007 Last Wednesday Eve Festival. Fireworks-related injuries were more common among households whose members had used homemade fireworks than among households whose members had used only commercially made fireworks (OR=16.5, 95% CI: 5.7-47.5). Forty-five households reported that they had sustained personal property damage caused by fireworks during the festival, costing a mean of US$ 36.60. Households with at least one injured member spent a mean of US$ 441.90 for medical care and a mean of US$ 70.80 for other expenses related to seeking medical care. The overall incidence of fireworks-related injury among household members was 0.2% (95% CI: 0.1-0.3%). Fireworks-related injury incidence was highest in the 10-19 age group. The total estimated number of fireworks-related injuries in Tehran during the 2007 Last Wednesday Eve Festival was approximately 17,000. Among the 20 injured individuals, 4 persons (20.0%) were hospitalised for a mean of 2.8 days. CONCLUSIONS The personal use of fireworks in Iran is associated with serious injuries and non-trivial economic costs. This study is the first to describe the incidence and economic costs of fireworks-related injuries in a major city in Iran using a population-based survey. To prevent these injuries, individuals should attend public fireworks displays conducted by professionals rather than engage in personal use of fireworks.

Abstract
BACKGROUND/AIMS Retinoblastoma is a highly malignant eye tumour in children with different survival rates across the world. The aims of this study are to determine the globe and patient survival in children with retinoblastoma in a major referral centre in Iran. METHODS 156 eyes of 105 consecutive patients with retinoblastoma were enrolled from 2001 to 2007. All demographic data, family history, presenting symptoms, duration of symptoms, ocular findings and treatment modalities that were used for the patients were collected. For patient survival, event was defined as death and for globe survival as enucleation. RESULTS The mean age at diagnosis was 28.5 months (unilateral 27.4 months; bilateral 30 months). Five patients had a positive family history. Fifty-two per cent of the cases were unilateral, and 48% were bilateral. The most common presenting sign was leucocoria (64.8%) followed by strabismus (28.2%). Enucleation was done primarily for 75.9% of unilateral cases and 34.3% of bilateral cases. Secondary enucleation was necessary in 5.6% and 7.8% of unilateral and bilaterally involved eyes respectively. Sixty-nine (44.2%) of 156 eyes were salvaged by different globe preserving modalities (unilateral 18.5%; bilateral 57.9%). The Kaplan-Meier survival estimate for globe preservation according to International Classification of Retinoblastoma (ICRB) was 100% for group A eyes, 93.5% for group B, 86.7% for group C, 57.1% for group D and 0% for group E eyes. Kaplan-Meier estimates for patients survival were 100% at 1 year, 94.8% at 3 years and 83.1% at 5 years. CONCLUSION Progress in methods of treatment, early detection of the disease and prompt referral to specialised centres have led to improved outcomes for patients with retinoblastoma in terms of globe and patients' survival rates even in developing countries.

Abstract
PURPOSE To compare the efficacy and safety of 1.25 mg versus 2.5 mg intravitreal bevacizumab (IVB) for treatment of choroidal neovascularization (CNV) associated with agerelated macular degeneration (AMD). METHODS In this randomized clinical trial, consecutive patients with active CNV associated with AMD received 1.25 mg or 2.5 mg IVB. Best corrected visual acuity (BCVA), foveal thickness and side effects of therapy were evaluated one and three months after intervention. RESULTS Overall 86 subjects were enrolled and completed the scheduled follow-up. Forty seven and 39 patients received 1.25 and 2.5 mg IVB respectively. The study groups were balanced in terms of baseline characteristics such as age, BCVA and foveal thickness. Mean improvement in BCVA was 0.06±0.3 logMAR in the 1.25 mg group and 0.07±0.34 logMAR in the 2.5 mg group (P=0.9). Mean decrease in foveal thickness was 49±36 μm in the 1.25 mg group and 65±31μm in the 2.5 mg group (P=0.6). Three cases of vitreous reaction and one case of massive subretinal hemorrhage were observed in the 2.5 mg group. CONCLUSION Double dose (2.5 mg) IVB does not seem to be more effective than regular dose (1.25 mg) injections for treatment of CNV due to AMD and may lead to more complications.

Abstract
A bilateral simultaneous cataract surgery (BSCS) was performed on a 67-year-old man. The surgeon had not changed the surgical settings in between the two procedures for the two eyes. The patient developed fulminant bilateral endophthalmitis a day following the BSCS. Intravitreal culture grew Pseudomonas aeruginosa . The source of infection was not found. Immediate bilateral vitrectomy and intravitreal, subconjunctival, topical and systemic antibiotic did not save the eyes. Patient ended up with bilateral visual loss.

Abstract
PURPOSE To evaluate plaque radiotherapy for iris melanoma. DESIGN Prospective noncomparative interventional case series. METHODS For 38 patients, custom-designed plaque radiotherapy using iodine 125 isotope was applied overlying the cornea with a tumor apex dose of 80 Gy. The main outcome measures were tumor control and ocular complications using Kaplan-Meier estimates and Cox proportional hazards regression analysis. RESULTS In all cases, the melanoma was nonresectable owing to large or discohesive tumor. The tumor configuration was nodular in 24 cases (63%) and flat (diffuse) in 14 (37%). The mean tumor basal diameter was 9 mm (range 4 to 13 mm). Solid tumor extended into the anterior chamber angle in 36 eyes (95%). Tumor seeds were noted on the iris stroma for a mean of 7 clock hours and in the anterior chamber angle for a mean of 4 clock hours. Five-year follow up revealed tumor metastasis in 0% and tumor recurrence in 8% of patients. Visual acuity of 20/200 or worse was found in 16% at 5 years. Radiation-related complications at 5 years included corneal epitheliopathy (9%), cataract (70%), and neovascular glaucoma (8%). No patients developed corneal necrosis, scleral necrosis, retinopathy, or papillopathy. After treatment, the combined incidence of tumor-related and radiation-related elevated intraocular pressure at 5 years was 33%. Enucleation was necessary in 13% at 5 years, for tumor recurrence (n = 3) and patient preference (n = 1). CONCLUSIONS Plaque radiotherapy is a useful alternative to enucleation for eyes with nonresectable iris melanoma. Tumor control is 92% at 5 years, but related complications, especially cataract and elevated intraocular pressure, should be anticipated.
