Abstract
A 71-year-old male presented with painless and slowly progressive proptosis of the right eye. The patient had no history of cancer and was in good health. Orbital magnetic resonance imaging showed a well-demarcated, slightly lobulated intraconal orbital mass hypo-isointense on T1- weighted and isointense on T2-weighted images, demonstrating contrast enhancement in the right orbit. The lesion had a central cavitary region. An anterior orbitotomy with lower lid crease incision was performed and the lesion was excised in toto. Histopathologic examination revealed diffuse infiltration of monomorphic population of small lymphoid cells. Immunohistochemical staining demonstrated diffuse and strong positivity for CD20, CD5, and cyclin D1. Histopathological and immunohistochemical findings were consistent with mantle cell lymphoma. Positron emission tomography-computed tomography did not show systemic involvement. The patient underwent orbital external beam radiotherapy (36 Gy). There was no recurrence and/or systemic involvement at 2.5 years follow-up.

Abstract
PURPOSE To determine the effect of patient and tumor features and different treatments on eye removal (enucleation or exenteration) and metastasis in posterior uveal melanoma (PUM). METHODS Retrospective analysis. Patient age (≤60 vs >60 years), sex (female vs male), visual acuity (VA, ≤20/40 vs >20/40), largest tumor basal diameter (LTBD), tumor thickness, tumor stage according to American Joint Committee on Cancer (AJCC) 8th edition, ciliary body involvement, distance to optic disc (OD)/fovea (≤3 mm vs >3 mm), OD involvement, and histopathology were evaluated. Primary treatment options were transpupillary thermotherapy, plaque radiotherapy, Cyberknife radiosurgery, exoresection, and eye removal. Risk factors for primary eye removal were determined using logistic regression test and those for secondary eye removal and metastasis with Cox regression analysis. RESULTS Of 387 cases, 153 (39.5%) underwent primary eye removal. Multivariable risk factors for primary eye removal included AJCC tumor stage (p = 0.001, OR:4.586; p < 0.001, OR:34.545; p < 0.001, OR:103.468 for stages T2, T3, and T4 vs stage T1, respectively), and VA≤20/40 (p = 0.014, OR:2.597). Multivariable risk factors for secondary eye removal were VA≤20/40 (p = 0.019, RR:2.817) and AJCC stage T3 vs T1 (p = 0.021, RR:2.666). Eye preservation rates in patients undergoing eye-conserving treatments were 80.3%, 69.6%, and 51.5% at 5, 10, and 15 years, respectively. Metastasis-free survival rates were 81.0%, 73.0%, and 56.7% at 5, 10, and 15 years, respectively. Multivariable risk factors for metastasis included eye removal as primary treatment (p = 0.005, RR:2.828) and mixed type histopathology (p < 0.001, RR:4.804). DISCUSSION Early diagnosis is crucial for both eye preservation and survival in PUM. Increasing AJCC tumor stage and lower VA were risk factors for eye removal in this study. Mixed type histopathology and primary eye removal were risk factors for metastasis.

Abstract
PURPOSE To report a rare case of atopic keratoconjunctivitis (AKC) presenting with bilateral corneal panni associated with limbal inclusion cysts in the left eye. MATERIALS & METHODS Retrospective case report. RESULTS A 19-year-old female with AKC presented with bilateral corneal panni and limbal inclusion cysts in the left eye. Anterior segment swept-source optical coherence tomography showed bilateral hyperreflective epicorneal membrane and a lobulated cystic lesion in the left eye. Ultrasound biomicroscopy demonstrated a dense membrane overriding the cornea in both eyes and hyporeflective spaces separated by medium reflective septa in the cyst. The patient underwent excision of the limbal inclusion cyst and pannus in the left eye. Histopathological examination revealed subepithelial cystic lesion surrounded by non-keratinizing epithelium; areas of acanthosis, hyperkeratosis, parakeratosis, and hyperplasia in the epithelium of the pannus; as well as inflammation, fibrosis, and increase in vascularization in the stroma. CONCLUSION To our knowledge, this is the first case of corneal pannus associated with limbal inclusion cysts in AKC. Surgical excision was done to establish the diagnosis as well as to improve vision in our case.

Abstract
This study aims to systematically review the reported literature on the use of anterior segment optical coherence tomography (AS-OCT) in ocular surface tumours and simulating lesions. A systematic literature search was done using PubMed, Scopus, and Web of Science databases between January 2002 and December 2021. On AS-OCT, ocular surface squamous neoplasia typically demonstrate epithelial thickening, epithelial hyperreflectivity, and an abrupt transition between normal and abnormal epithelium. Conjunctival nevi usually show mildly hyperreflective epithelium of normal thickness, internal hyperreflectivity, and intralesional cysts which is the hallmark of this tumour. Primary acquired melanosis presents with normal thickness epithelium, basal epithelial hyperreflectivity, and absence of cysts. Conjunctival melanoma demonstrates hyperreflective normal/thickened epithelium, hyperreflective basal epithelium, internal hyperreflectivity, and absence of intralesional cysts. Conjunctival lymphoma shows homogenous, low-medium reflective subepithelial lesions with smooth borders, and dot-like infiltrates. Benign reactive lymphoid hyperplasia findings are similar to lymphoma but the infiltrates are more hyperreflective compared to lymphoma. Pterygium shows thickened conjunctival epithelium, epithelial hyperreflectivity, and subepithelial wedge-shaped hyperreflective tissue separated from the overlying epithelium by a cleavage plane. Pinguecula demonstrates mildly thickened epithelium and similar findings with pterygium but does not extend beyond the corneal limbus. This review shows that AS-OCT, as a noninvasive tool, has potential uses in the differential diagnosis of ocular surface tumours and simulating lesions. Major limitations of AS-OCT include limited visualization of the posterior border of thick, keratinized, and pigmented tumours and lack of assessment of large conjunctival tumours in a single cut.

Abstract
Optical coherence tomography (OCT) is a non-invasive method that provides the opportunity to examine tissues by taking cross-sectional images. OCT is increasingly being used to evaluate anterior segment (AS) pathologies. Swept-source (SS) OCT allows greater penetration and achieves better visualization of the internal configuration of AS tissues due to the longer wavelength employed and high scan speeds. We reviewed the utilization of AS SS-OCT in various conditions including glaucoma, ocular surface pathologies, iris tumors, refractive surgery, cataract surgery, and scleral diseases. A systematic literature search was carried out on PubMed, Scopus, and Web of Science databases between January 1, 2008, and September 1, 2022 using the following keywords: AS SS-OCT; dry eye and SS-OCT; ocular surface and SS-OCT; cornea and SS-OCT; dystrophy and SS-OCT; glaucoma and SS-OCT; ocular surface tumors and SS-OCT; conjunctival tumors and SS-OCT; refractive surgery and SS-OCT; cataract and SS-OCT; biometry and SS-OCT; sclera and SS-OCT; iris and SS-OCT; ciliary body and SS-OCT; artificial intelligence and SS-OCT. A total of 221 studies were included in this review. Review of the existing literature shows that SS-OCT offers several advantages in the diagnosis of AS diseases. Exclusive features of SS-OCT including rapid scanning, deeper tissue penetration, and better image quality help improve our understanding of various AS pathologies.

Abstract
PURPOSE To report wide-field fundus imaging and fluorescein angiography findings in conditions mimicking retinoblastoma (pseudoretinoblastoma). METHODS The clinical and imaging records of 28 patients (36 eyes) imaged with RetCam 3 (Clarity Medical Systems, Inc) wide-field fundus photography and fluorescein angiography who were diagnosed as having various pseudoretinoblastoma disorders between February 2020 and August 2021 were retrospectively evaluated. RESULTS Most patients were referred with suspicion of retinoblastoma. Other patients had unresolved eye conditions and received initial treatment elsewhere and they were referred later for exclusion of retinoblastoma. On RetCam fundus photography and fluorescein angiography, pseudoretinoblastoma conditions were diagnosed as Coats disease (9 eyes), congenital glaucoma (3 eyes), persistent fetal vasculature (3 eyes), familial exudative vitreoretinopathy (2 eyes), retinopathy of prematurity (2 eyes), myelinated retinal nerve fibers (2 eyes), optic nerve hypoplasia (2 eyes), oculocutaneous albinism (2 eyes), meridional fold (2 eyes), combined hamartoma of retina and retinal pigment epithelium (2 eyes), grouped congenital hypertrophy of the retinal pigment epithelium (1 eye), retinal astrocytic hamartoma (1 eye), morning glory syndrome (1 eye), optic glioma (1 eye), giant choroidal nevus (1 eye), vasculitis (1 eye), and chorioretinitis (1 eye). RetCam imaging and fluorescein angiography demonstrated telangiectasias, microaneurysms, submacular exudation/fibrosis, capillary non-perfusion, and exudation posterior to telangiectasias in Coats disease. Hypofluorescent optic discs, peripheral non-perfusion, and vascular leakage were observed in congenital glaucoma. Large areas of capillary non-perfusion, poor foveal morphology/formation, elongated ciliary processes with hyperfluorescent central core, and hyperfluorescent fibrovascular stalk at the posterior pole were hallmarks of persistent fetal vasculature. CONCLUSIONS RetCam wide-field fundus imaging and fluorescein angiography play an important role in the diagnosis of conditions simulating retinoblastoma.

Abstract
PURPOSE To investigate the distribution of pseudoretinoblastoma (PSRB) cases based on gender, age, and laterality. MATERIALS AND METHODS The clinical records of 607 patients (851 eyes) who were referred for diagnosis of retinoblastoma or simulating conditions between October 1998 and May 2021 were retrospectively evaluated. Patients were stratified by age as follows: ≤1 year, >1-3 years, >3-5 years, and >5 years. RESULTS Of 190/607 PSRB patients, 129 (67.9%) were males and 61 (32.1%) females (p = 0.001). The 3 most common diagnoses in males were Coats disease (20.2%), persistent fetal vasculature (PFV, 14.0%), and chorioretinal coloboma (6.2%). In females, the 3 most common diagnoses included PFV (21.3%), retinal dysplasia, congenital glaucoma, and combined hamartoma (each 6.6%). PFV was the most common diagnosis in ≤1 year old patient group (26.6%). Coats disease and PFV were the most common diagnoses in >1-3 years old patient group (each 16.7%). Coats disease was the most common diagnosis in >3-5 years old (30.8%) and >5 years old patient groups (13.1%). PSRBs were unilateral in 121/190 (63.7%) patients. Coats disease usually presented unilaterally (p < 0.001) while PFV, optic nerve head drusen, and retinopathy of prematurity as bilateral diseases (p = 0.019, p = 0.001, and p = 0.001 respectively). DISCUSSION PSRB diagnoses show differences depending on gender, age, and laterality. In our study, the most common PSRB lesions were Coats disease in males and PFV in females. PFV was the most frequent diagnosis in ≤3 years and Coats disease in >3 years of age groups. Coats disease and PFV were the most common unilateral and bilateral PSRB diagnoses respectively.

Abstract
Hamartomas are local malformation of cells that demonstrate abnormal proliferation in the area where they are normally present. Retinal and optic disc hamartomas include astrocytic hamartoma, congenital hypertrophy of the retinal pigment epithelium (CHRPE), simple congenital hamartoma of the retinal pigment epithelium (CSHRPE), combined hamartoma of the retina and retinal pigment epithelium (CHRRPE), retinal hemangioblastoma (retinal capillary hemangioma), and retinal cavernous hemangioma. Retinal and optic disc hamartomas can be observed sporadically as well as with systemic associations. Astrocytic hamartoma usually appears as a flat, transparent yellowish lesion. CHRPE is a round, pigmented, and flat lesion. CSHRPE usually presents as a dark black macular tumor. CHRRPE consists of vascular, glial, and pigment epithelial components, which can demonstrate peripapillary, macular, and peripheral localization. Retinal hemangioblastoma is a vascular tumor, red-pink in color with tortuous and dilated afferent and efferent vessels, typically located in the peripheral retina or optic disc. Retinal cavernous hemangioma is characterized by the formation of thin-walled saccular angiomatous structures in the retina or optic nerve head resembling concord grapes. Ultrasonography, fundus autofluorescence, optical coherence tomography, optical coherence tomography angiography, and fluorescein angiography methods are used in the diagnosis of retinal and optic disc hamartomas. Some retinal and optic disc hamartomas do not require treatment. However, complications including vitreous hemorrhage, macular exudation, retinal detachment, macular hole, epiretinal membrane, and choroidal neovascularization require treatment.

Abstract
We report a case of bilateral optic nerve head drusen complicated by choroidal neovascularization (CNV) in the left eye at presentation. The presence of optic disc and macular edema in addition to exudation led to the misdiagnosis of neuroretinitis at an outside medical center. Swept-source optical coherence tomography (SS-OCT) and SSOCT angiography were critical in establishing the diagnosis and follow-up in a noninvasive manner. Secondary CNV associated with optic nerve head drusen responded well to intravitreal injections of anti-vascular endothelial growth factor in the left eye. Asymptomatic nonexudative CNV that developed in the right eye during follow-up regressed spontaneously without treatment. [Ophthalmic Surg Lasers Imaging Retina 2022;53:518-521.].

Abstract
OBJECTIVES To investigate the results of partial lamellar sclerouvectomy (PLSU) for anteriorly located uveal tumours. METHODS We reviewed the tumour features, histopathologic findings, complications, visual acuity outcomes, eye preservation, metastasis, and mortality data of 56 cases with uveal tumours who underwent PLSU between February 1999 and February 2019. RESULTS The mean largest tumour base diameters were 5.8 × 3.4 mm and the mean tumour thickness was 3.3 mm. Histopathologically, 30 (53.6%) eyes had malignant melanoma, 13 (23.2%) had nevus, 5 (8.9%) had iris stromal cyst, 4 (7.1%) had melanocytoma, 2 (3.6%) had Fuchs' adenoma, 1 (1.8%) had iris pigment epithelial cyst, and 1 (1.8%) had invasive breast cancer metastasis. The most common postoperative complications included cataract in 21 (37.5%) eyes, vitreous haemorrhage in 15 (26.8%), scleral thinning in 10 (17.9%), and hyphema in 6 (10.7%). At a mean follow-up of 40.4 (range: 10-201) months, tumour recurrence was observed in 2/30 (6.7%) eyes with melanoma and 1/5 (20.0%) eye with iris stromal cyst. Eyes with recurrent melanoma were treated with enucleation. Liver metastasis developed in only 1 (3.3%) melanoma case. All patients were alive at the end of follow-up. CONCLUSIONS PLSU is a successful treatment method for many anteriorly located uveal tumours. In our series, the overall tumour recurrence and globe salvage rates were 5.4% and 96.4% respectively. Among melanoma cases, the metastasis rate was 3.3% and survival rate was 100%.

Abstract
Surgery in intraocular tumors is done for excision/biopsy and the management of complications secondary to the treatment of these tumors. Excision/biopsy of intraocular tumors can be done via fine-needle aspiration biopsy (FNAB), transretinal biopsy (TRB), partial lamellar sclerouvectomy (PLSU), and endoresection. FNAB, TRB, and PLSU can be used in tumors that cannot be diagnosed by clinical examination and other ancillary testing methods. PLSU is employed in tumors involving the iridociliary region and choroid anterior to the equator. Excisional PLSU is performed for iridociliary and ciliary body tumors with less than 3 clock hours of iris and ciliary body involvement and choroidal tumors with a base diameter less than 15 mm. However, for biopsy, PLSU can be employed with any size tumor. Endoresection is a procedure whereby the intraocular tumor is excised using vitrectomy techniques. The rationale for performing endoresection is based on the fact that irradiated uveal melanomas may cause complications such as exudation, neovascular glaucoma, and intraocular pigment and tumor dissemination (toxic tumor syndrome), and removing the dead tumor tissue may contribute to better visual outcome. Endoresection is recommended 1-2 weeks after external radiotherapy. Pars plana vitrectomy is also used in the management of complications including vitreous hemorrhage, retinal detachment, and epiretinal membrane that can occur after treatment of posterior segment tumors using radiotherapy and transpupillary thermotherapy. It is important to make sure the intraocular tumor has been eradicated before embarking on such treatment.

Abstract
We report a case of unilateral varicella-zoster virus (VZV) related keratouveitis and papillitis. A 54-year-old male presented with headache, left forehead rash, and decreased vision in the left eye. Examination of the left eye showed visual acuity (VA) of 0.15, relative afferent pupillary defect, anterior stromal corneal edema, nongranulomatous keratic precipitates, a swollen and hyperemic optic disc. The patient could read 6/12 of the Ishihara plates in the left eye. Optical coherence tomography (OCT) showed optic disc edema and OCT angiography (OCTA) revealed increased peripapillary vascularity. Computerized visual field testing demonstrated an enlarged blind spot and lower altitudinal defect. Serum anti-varicella-zoster IgM antibody level was elevated. The patient was put on oral acyclovir and prednisone treatment. At 1-month follow-up visit, VA increased to 0.9 and color vision was 11/12 Ishihara plates. OCT showed resolution of optic disc edema and OCTA demonstrated normalization of the increased peripapillary vascularity. Computerized visual field test demonstrated improvement in the lower altitudinal visual field defect and normalization of the enlarged blind spot. Optic nerve involvement in VZV infection occurs rarely, especially in immunocompetent patients as in our case.

Abstract
CLINICAL RELEVANCE This study investigates the demographic and clinical features of conjunctival tumours. BACKGROUND Conjunctival tumours include a large spectrum of conditions ranging from benign lesions to aggressive, life-threatening malignancies. Knowing the distribution of conjunctival tumours by age and gender is important for reducing cancer morbidity. METHODS The clinical records of 375 patients (410 eyes) diagnosed with a conjunctival mass at a tertiary referral centre between February 1999 and November 2020 were retrospectively evaluated. RESULTS Two-hundred-seventeen (57.9%) patients were male and 158 (42.1%) were female. Of 410 conjunctival tumours, 159 (38.8%) were benign, 106 (25.9%) premalignant, and 145 (35.4%) malignant. Overall, the 3 most common diagnoses were squamous cell carcinoma (SCC, 19.5%), conjunctival intraepithelial neoplasia (CIN, 18.3%), and naevus (17.8%). The most common benign, premalignant, and malignant tumours were naevus (n = 73/159, 45.9%), CIN (n = 75/106, 70.8%), and SCC (n = 80/145, 55.2%) respectively. Naevus was the most common tumour in ≤20 years and > 20-40 years old patient groups (56.2% and 25.4% respectively). CIN was the most frequent tumour in patients aged > 40-60 years (25.7%). SCC was the most common tumour in > 60-80 years and > 80 years old patient groups (44.3% and 80.0% respectively). The median patient age was greater in patients with malignant tumours (64.5 years) compared to patients with premalignant (55.5 years, p = 0.011) and benign tumours (22.0 years, p < 0.001). Malignant tumours displayed larger base diameter, greater thickness, and intrinsic vessels compared to premalignant or benign lesions (p < 0.001 for each parameter). Malignant tumours also displayed more amelanotic vs melanotic appearance (p < 0.001) and limbal vs extralimbal bulbar location compared to benign lesions (p < 0.001). CONCLUSION Premalignant and malignant tumours comprised 61.2% of all conjunctival tumours and were usually detected in patients > 40 years of age in this study.

Abstract
PURPOSE To compare the efficacy of transpupillary thermotherapy (TTT), indocyanine green-enhanced TTT (ICG-TTT), and photodynamic therapy (PDT) in the management of circumscribed choroidal hemangioma (CCH) and to investigate the baseline clinical features effecting treatment outcomes METHODS: Retrospective review of clinical records of 60 eyes with CCH which underwent TTT (25), ICG-TTT (22), or PDT (13). Main study outcomes were 1) final visual acuity (VA) ≤20/200, 2) <2 Snellen lines VA increase, 3) persistent subretinal fluid (SRF), and 4) <20% decrease in tumor thickness. RESULTS Multivariable factors associated with final VA ≤20/200 included longer duration of symptoms (p = 0.015), lower initial VA (p = 0.030), and presence of retinoschisis overlying the tumor (p = 0.047). Multivariable factors for <2 Snellen lines VA increase were longer duration of symptoms (p = 0.018) and previous failed treatment (p = 0.003). By multivariable analysis, the only significant factor for persistent SRF was the presence of retinoschisis (p = 0.001). Multivariable factors associated with a decrease in tumor thickness by <20% were smaller initial tumor thickness (p = 0.045) and presence of retinoschisis (p = 0.014). By Pearson Chi-Square/Fisher Exact Test, final VA ≤20/200 rates (48.0%, 13.6%, 30.8% respectively, p = 0.041) and VA improvement by <2 lines rates (64.0%, 27.3%, 38.5% respectively, p = 0.036) were significantly different between TTT, ICG-TTT, and PDT groups. However, by post hoc analysis, ICG-TTT yielded statistically better outcomes compared to TTT with respect to final visual acuity (VA) ≤20/200 (p = 0.012) and <2 Snellen lines VA increase (p = 0.012). CONCLUSIONS Longer symptom duration, previous failed treatment, lower initial VA, and presence of retinoschisis were risk factors for worse visual outcomes. Eyes with retinoschisis displayed more SRF persistence after treatment. Smaller initial tumor thickness and presence of retinoschisis were risk factors for <20% decrease in tumor thickness.

Abstract
PURPOSE To evaluate the risk factors leading to recurrence and new tumor (NT) development in patients with retinoblastoma after intravenous chemotherapy (IVC) and to review the treatment outcomes. MATERIALS AND METHODS The records of 166 retinoblastoma cases (having 246 affected eyes) who underwent six-cycle IVC (vincristine, etoposide, and carboplatin) as primary treatment between October 1999 and August 2020 were reviewed retrospectively. RESULTS The mean ages at presentation were 9.0 (median: 8.0) and 9.2 (median: 8.5) months in cases with recurrence and NTs respectively. Recurrence was detected in 40 (16.3%) eyes, NTs in 29 (11.8%), and both recurrence/NTs in 24 (9.8%). The mean time elapsed till recurrence and NT was 10.7 months. Multivariable analysis showed that the factors predictive of recurrence were largest tumor base diameter (LTBD) >12 mm (p = 0.039) and presence of subretinal seeds at diagnosis (p = 0.043). Multivariable risk factors for the development of NTs were bilateral familial retinoblastoma (p = 0.001) and presence of subretinal seeds at diagnosis (p = 0.010). Mean follow-up was 80.1 (median: 72.5) months. By Kaplan-Meier analysis, the 1-, 3-, and 6-year recurrence and NT rates were 21.2%, 28.1%, and 28.7% and 14.9%, 22.6%, and 23.9% respectively. The most common treatment methods used for recurrent and/or NTs included cryotherapy, transpupillary thermotherapy, and intra-arterial chemotherapy. Enucleation was eventually required in 24/93 (25.8%) eyes. No patient developed metastasis. DISCUSSION Development of recurrence and/or NT after IVC was noted in 38% of all retinoblastoma eyes. Bilateral familial disease, LTBD >12 mm, and presence of subretinal seeds at baseline were risk factors for recurrence and NTs in this study.

Abstract
PURPOSE To review the authors' experience in the diagnosis of retinoblastoma and to explore the frequency of intraocular conditions that mimic this malignancy according to patient age at presentation. METHODS This was a retrospective observational study including 549 patients (769 eyes) who were referred for confirmation and/or management of retinoblastoma between October 1998 and June 2019 at a single tertiary center. A detailed ocular examination was done by the same ocular oncologist under general anesthesia for every patient. RESULTS Of 549 patients referred for diagnostic confirmation or management of retinoblastoma, 393 (71.6%) patients were found to have retinoblastoma and 156 (28.4%) patients received the diagnosis of pseudoretinoblastoma. The mean patient age at presentation was 52.1 months, ranging from 1 to 276 months. The most common diagnoses among patients with pseudoretinoblastoma younger than 1 year were persistent fetal vasculature (PFV) (n = 19; 28.8%), Coats disease (n = 7; 10.6%), chorioretinal coloboma (n = 4; 6.1%), retinal dysplasia (n = 4; 6.1%), and retinal detachment (n = 4; 6.1%). In patients with pseudoretinoblastoma who were 1 to 5 years old, the most common diagnoses were Coats disease (n = 10; 25.6%), PFV (n = 7; 17.9%), and optic disc hypoplasia (n = 3; 7.7%). Patients older than 5 years were most likely to have Coats disease (n = 8; 15.7%), optic disc drusen (n = 5; 9.8%), retinopathy of prematurity (n = 4; 7.8%), and combined hamartoma (n = 4; 7.8%). CONCLUSIONS This study shows that 28.4% of patients referred for suspicion or management of retinoblastoma were classified as having pseudoretinoblastoma. The most common conditions causing diagnostic confusion with retinoblastoma included PFV and Coats disease, similar to previous publications from both high-and low-income countries.

Abstract
PURPOSE To evaluate the cytopathological results, surgical complications, and patient outcomes after transretinal biopsy (TRB) for diagnosis of retinal/choroidal tumors METHODS: Records of 40 cases who underwent TRB via 23-gauge (23 G) pars plana vitrectomy between March 2011 and March 2020 were reviewed. STUDY DESIGN Retrospective. RESULTS Twenty-six (65.0%) cases were women and 14 (35.0%) were men. The mean age at diagnosis was 57.2 (range: 18-83) years. The mean tumor base diameter was 12.0×9.8 mm and the mean tumor thickness was 4.9 mm. According to cytopathological examination, 29 (72.5%) cases had choroidal melanoma, 2 (5.0%) had non-small cell lung cancer metastasis, 1 (2.5%) had adenoma of retinal pigment epithelium, 1 (2.5%) had small cell lung cancer metastasis, 1 (2.5%) had invasive breast cancer metastasis, 1 (2.5%) had retinal astrocytic hamartoma, and 1 (2.5%) had pseudoneoplastic gliosis. Cytopathological examination of 4 (10.0%) cases revealed findings consistent with macular and extramacular degeneration. Postoperative complications were mild vitreous hemorrhage in 16 (40.0%) cases, gradually worsening cataract in 4 (11.8%), retinal detachment in 1 (2.5%), hyphema in 1 (2.5%), glaucoma in 1 (2.5%), and macular hole in 1 (2.5%). During the mean 11.1 (range: 1-55) months follow-up, 1 (3.4%) patient with choroidal melanoma developed liver metastasis. All patients were alive at the end of follow-up. CONCLUSIONS TRB using 23 G pars plana vitrectomy can be used to make the cytopathologic diagnosis of retinal/choroidal tumors whenever the clinical diagnosis is not certain or in cases with known diagnosis to obtain information on cell type/cytogenetics. In our series, the most common diagnosis after cytopathologic examination was choroidal melanoma.

Abstract
PURPOSE To evaluate the results of secondary intra-arterial chemotherapy (IAC) and/or intravitreal chemotherapy (IVC) as a salvage treatment for retinoblastoma (RB). MATERIALS AND METHODS The medical records of 31 (20 male, 11 female) cases (with 38 eyes) who underwent secondary IAC and/or IVC between February 2010 and June 2019 were retrospectively reviewed. RESULTS Thirteen (41.9%) cases had unilateral and 18 (58.1%) had bilateral RB. According to the International Classification of RB, 6 (15.8%) eyes had group B, 9 (23.7%) eyes had group C, 16 (42.1%) eyes had group D, and 7 (18.4%) eyes had group E RB at diagnosis. All patients underwent six-cycle intravenous chemotherapy as primary treatment and 8 eyes received external radiotherapy before IAC/IVC. Secondary IAC was performed in 21 (55.3%) eyes, IVC in 10 (26.3%) eyes, and IAC + IVC in 7 (18.4%) eyes. External radiotherapy was applied in 2 (5.3%) eyes after IAC/IVC, one of which was later enucleated. In total, 17 (44.7%) eyes undergoing secondary IAC/IVC treatments were enucleated. Metastasis and death were not observed in any case during the mean follow-up period of 59.3 (median 61, range: 10-98) months. DISCUSSION Although 60.5% of the eyes undergoing IAC/IVC consisted of groups D and E RB, globe salvage and survival rates were 55.3% and 100.0%, respectively. External radiotherapy was required in 5.3% of the eyes after IAC/IVC. In conclusion, IAC and IVC are safe and effective treatment methods in eyes with RB unresponsive to other eye-preserving treatments and those demonstrating recurrence.

Abstract
OBJECTIVES To report the swept-source optical coherence tomography angiography (SS-OCTA) findings in choroidal and retinal tumors. METHODS A retrospective noncomparative interventional case series of 60 eyes having various choroidal and retinal tumors imaged with SS-OCTA (Topcon DR1 Triton Plus, Tokyo, Japan) between September 2018 and February 2020 was conducted. Inclusion criteria were tumor thickness <4 mm, tumor base diameter <10 mm, and tumor location at the posterior pole. RESULTS Choroidal nevi usually demonstrated well-defined borders, hyperreflective internal structure, and no outer retinal involvement on SS-OCTA. Choroidal melanoma, in contrast to nevi, usually had ill-defined borders (p = 0.018), mixed hyperreflective-hyporeflective or hyperreflective internal structure (p = 0.014), and demonstrated outer retinal involvement (p < 0.001). Circumscribed choroidal hemangioma usually presented with well-defined borders, a hyperreflective internal tumor structure with multiple dilated interconnected tumor vessels intermixed with signal void areas representing connective tissue. Optic disc melanocytomas showed a hyporeflective plexus related to blocking of signal by the pigment and an intact radial peripapillary capillary network. There was flow on the surface and slightly deeper within the lesion on B-scan angiography overlay. Retinal astrocytic hamartomas had well-defined borders and a hyperreflective vascular plexus in the superficial and deep retina. Outer retina and choriocapillaris showed hyporeflective change due to shadowing/masking from calcium or high blood flow in the lesion. CONCLUSIONS Each of the different retinal and choroidal tumors studied in this series presented with different SS-OCTA features to aid in the differential diagnosis of these conditions. Good quality images are obtained in patients with good fixation and tumors <3 mm in thickness located at the posterior pole.

Abstract
PURPOSE To describe clinical, anterior segment optical coherence tomography (AS-OCT), in vivo confocal microscopy (IVCM), histopathologic, and immunohistochemical findings in a patient with multiple endocrine neoplasia type 2b (MEN 2b) syndrome. MATERIALS AND METHODS Retrospective case report of a patient with MEN 2b. RESULTS A 31-year-old male diagnosed with MEN 2b presented with eye redness, burning, and visible conjunctival mass in both eyes. The patient's past medical history revealed that he underwent bilateral adrenalectomy and total thyroidectomy. Genetic testing revealed M918T heterozygous mutation in the RET proto-oncogene. Corrected visual acuity was 20/20 in both eyes. Anterior segment examination revealed bilateral thickened lid margins, ectropion, blepharitis, conjunctival injection, temporal and inferonasal subconjunctival lesions with corneal invasion, corneal neovascularization, and marked corneal nerves. AS-OCT showed a subepithelial mixed reflective lobular mass in both eyes. Hyperreflective and noticeable thickened stromal corneal nerves were observed on IVCM in the left eye. After incisional biopsy of the right perilimbal lesions, histopathological examination revealed that lesions consisted of spindle cells in hypocellular bundles with no atypia and mitosis. Immunohistochemical examination revealed diffuse staining with S100, focal staining with synaptophysin, and no staining with neurofilament protein. These findings were considered compatible with a benign nerve sheath tumor, probably schwannoma. CONCLUSIONS We present clinical, AS-OCT, IVCM, histopathological, and immunohistochemical findings in a patient with MEN 2b. To our knowledge, this is the first case of a conjunctival schwannoma diagnosed histopathologically in MEN 2b.

Abstract
Objectives To evaluate the long-term treatment outcomes in intraocular retinoblastoma (RB) including the associated factors for eventual treatment with external beam radiotherapy (EBRT) and enucleation as well as to analyse the risk factors for metastasis and death in extraocular RB. Methods Retrospective analysis of 390 eyes from 256 (89.8%) intraocular RB and 29 (10.2%) extraocular RB cases diagnosed and treated between October 1998 and May 2018 at one of the largest tertiary care centers in Turkey. Results Of 351 intraocular RB eyes, 53.3% had group D/E disease at presentation. 75 (21.4%) of 351 eyes underwent primary enucleation. Of the remaining 276 eyes undergoing eye-conserving treatments, 201 (72.8%) were salvaged. Most of these eyes were treated using intravenous chemotherapy and/or focal treatments [transpupillary thermotherapy (TTT) and cryotherapy] initially. EBRT was eventually required in 48 (17.4%) eyes and secondary enucleation in 75 (27.2%) eyes. At mean follow-ups of 76.7 and 39.7 months for intraocular and extraocular RB cohorts, respectively, 180 (46.2%) eyes underwent primary/secondary enucleation and exenteration. Overall, 13 cases developed metastasis and 9 died. Two patients with trilateral RB also expired. Multivariable risk factors for enucleation were the presence of vitreous seeds (p < 0.001), absence of EBRT administration (p = 0.033), 5–9 TTT applications compared with no TTT (p = 0.031), and each 1 mm increase in tumour base diameter (p < 0.001). Univariate factors predictive of metastasis were the presence of extraocular RB detected by imaging methods (p < 0.001) and extrascleral/optic nerve cut end involvement at histopathological examination (p < 0.001). Conclusions In our series, 72.8% of the intraocular RB eyes undergoing eye-conserving treatments were saved. The globe salvage rate for all intraocular and extraocular RB eyes was 53.8% and the overall survival rate was 96.1%.

Abstract
AIM To evaluate the risk factors leading to recurrence in patients with ocular surface squamous neoplasia (OSSN). METHODS The records of 112 patients with OSSN who underwent treatment and follow-up between February 1999 and August 2018 were reviewed retrospectively. RESULTS Totally 67 patients (59.8%) were male and 45 patients (40.2%) were female. The mean age at presentation was 63.7y (range 22-87y). Partial lamellar scleroconjunctivectomy (PLSC) was performed in 105 (93.7%) cases and enucleation was performed in 7 (6.3%) cases due to bulbus invasion as the first step treatment. Treatments used in addition to PLSC included cryotherapy in 78 eyes (74.3%), alcohol epitheliectomy in 57 eyes (54.3%) for presence of corneal involvement, and amniotic membrane transplantation in 17 eyes (16.2%) for ocular surface reconstruction. Topical mitomycin C was used in 10 patients (9.5%) and strontium-90 (Str-90) treatment in 4 (3.8%) patients because surgical margins were tumor positive at the histopathological examination. Postoperative histopathologic diagnoses were squamous cell carcinoma (52 cases), carcinoma in situ (44 cases), moderate conjunctival intraepithelial neoplasia (11 cases), and mild conjunctiva intraepithelial neoplasia (5 cases). At a mean follow-up of 20.1mo, tumor recurrence was observed in 21 (18.8%) cases. The rate of recurrence was found to be lower in cases that underwent supplemental cryotherapy compared to those that did not (P<0.001). There was no metastasis in any case. CONCLUSION In our series, the recurrence rate is 18.8% and overall globe salvage rate is 90.2% for OSSN at relatively short-term follow-up.

Abstract
OBJECTIVES The aim of this study is to evaluate the effects of calisthenic exercises on balance, walking speed, fatigue, quality of life, and psychological status in patients with Multiple Sclerosis (MS). PATIENTS AND METHODS Forty patients diagnosed with MS were randomized into two exercise groups (group 1 = hospital-based, group 2 = home-based). Outcome measures including the MS International Quality of Life Scale, 10-meter walking test, Berg Balance Scale, Fatigue Severity Scale and the Hospital Anxiety Depression Inventory were assessed at the baseline and at 12-weeks. RESULTS Thirty-six participants completed the exercise programme (hospital based = 16, home based = 20). The mean age was 32.83 ± 3.64 years. The mean duration of disease was 6.97 ± 3.15 years. Hospital-based and home-based exercise groups had significant improvements in the balance, 10-meter walking test, anxiety, and the quality of life after the 12-week exercise programme. There was a significant improvement in the hospital-based patients in terms of the depression scores. No significant improvement was observed in terms of fatigue in any of the groups. When both groups were compared, the improvement in the balance and depression scores of the hospital-based patients was significantly higher than the home-based patients. CONCLUSIONS Calisthenic exercises can be easily performed both at home and in hospital setting. In patients with MS, calisthenic exercises performed at home or at the hospital may improve the balance, quality of life, and the functional and psychological status, while no significant effect has been observed on fatigue.
