A 63-year-old Caucasian man with metastatic lung adenocarcinoma undergoing chemotherapy and external radiotherapy was referred for routine eye examination. Although he was asymptomatic, ocular examination revealed a relatively well-circumscribed whitish retinal lesion measuring 0.5×0.5×0.5 mm located along the inferotemporal vascular arcade in the right eye. Optical coherence tomography (OCT) showed a hyperreflective dome-shaped lesion occupying the inner retinal layers with few hyperreflective dots overlying the retina in the posterior vitreous consistent with tumor cells. Fluorescein angiography revealed early hyperfluorescence and late staining without leakage at the lesion site. A diagnosis of presumed retinal metastasis from lung adenocarcinoma was made. At 2 months follow-up after completion of chemotherapy, the retinal lesion was found to have regressed completely leaving minor irregularities in the inner retinal layers on OCT. To date, there have been only 41 cases of carcinoma metastasis to the retina reported in the literature including the current case. Despite its rarity, retinal metastasis should be considered in the differential diagnosis of a white-yellow retinal mass with/without overlying vitreous cells especially in patients with a history of systemic cancer.

AIM: To evaluate the results and complications of secondary endoresection via pars plana vitrectomy for choroidal melanoma and review the previously reported endoresection studies on the treatment of choroidal melanoma. METHODS: The medical records of 6 patients with choroidal melanoma who underwent secondary endoresection between March 2012 and March 2020 were retrospectively reviewed. The indications for secondary endoresection were progressive or recurrent tumor and severe exudative retinal detachment after previous treatment with plaque radiotherapy/Cyberknife radiosurgery/transpupillary thermotherapy (TTT). RESULTS: Before endoresection, 2 eyes had Iodine-125 plaque radiotherapy and TTT, 1 eye had Ruthenium-106 plaque radiotherapy and TTT, 1 eye had Cyberknife radiosurgery and TTT, 1 eye had Cyberknife radiosurgery, and 1 eye had TTT only. Preoperative visual acuity ranged from 20/63 to 20/1600 (Snellen) and from 0.5 to 1.9 (mean: 1.1) on the logMAR scale. The mean tumor base diameters were 9.5×8.7 mm and the mean tumor thickness was 5.4 mm. After secondary endoresection, transient vitreous hemorrhage developed in 2 (33.3%) eyes and retinal detachment in 1 (16.7%) eye. Cytopathological examination revealed epithelioid cell melanoma in 4 (66.7%) eyes and mixed cell melanoma in 1 (16.7%). Melanoma cell type was not specified in 1 (16.7%) eye. At a mean follow-up of 49.6mo (range: 16-90mo), mean visual acuity did not improve and 1 eye was enucleated due to tumor recurrence. Final visual acuity ranged from 20/63 to 20/1600 (Snellen) and from 0.5 to 1.9 (mean: 1.2) on the logMAR scale. Two patients with choroidal melanoma developed metastasis and eventually expired. CONCLUSION: Secondary endoresection seems to be an effective treatment option for globe salvage in choroidal melanoma not responsive to conventional treatment and displaying persistent exudative retinal detachment. There was no visual acuity increase among the treated eyes but globe salvage was possible in most cases in this study.

A 43-year-old patient presented with painless proptosis, limited upgaze, and vision loss in the right eye. Funduscopic examination revealed right optic disc edema and subtle macular compression. Swept-source optical coherence tomography (SS-OCT) revealed a smooth contoured elevation of the posterior pole without any distortion of retinal structures, an appearance closely simulating dome-shaped maculopathy. Swept-source optical coherence tomography angiography (SS-OCTA) revealed normal retinal and choroidal vasculature. Orbital magnetic resonance imaging demonstrated a well-circumscribed intraconal mass compressing the globe and optic nerve in the right orbit. An anterior orbitotomy was performed, whereby the tumor was totally excised and diagnosed histopathologically as cavernous hemangioma. This case represents an orbital cavernous hemangioma touching the eyeball and producing compression of the posterior pole presenting with a dome-shaped maculopathy-like appearance on SS-OCT. SS-OCT and SS-OCTA are important noninvasive tools for evaluating the retinal and choroidal effects in orbital tumors.

A 22-year-old woman presented with progressive swelling of the nasal conjunctiva in the left eye. Anterior segment examination revealed a diffuse cystic appearance to the inferonasal bulbar conjunctiva and plica semilunaris. Anterior segment swept-source optical coherence tomography (OCT) revealed clear hyporeflective spaces demarcated by hyperreflective septae in the affected conjunctiva, consistent with the diagnosis of lymphatic malformation (LM). Magnetic resonance imaging revealed a well circumscribed intraconal mass located inferonasally in the left orbit. Systemic examination revealed a lesion similar to LM on the left hard palate. The left conjunctival mass was excised subtotally. Subsequently, a transconjunctival anterior orbitotomy was performed and the left orbital mass was completely removed intact. Histopathologically, the conjunctival mass was diagnosed as LM and the orbital mass as venous malformation (VM). This case represents a rare coexistence of histopathologically proven conjunctival LM and orbital VM as well as a presumed LM of the hard palate, all 3 lesions occurring in the ipsilateral midface area.

Tiroid oftalmopati, Graves Hastalığı'nın en önemli tiroid dışı bulgusu olup göz tutulumu sıklıkla tiroid fonksiyon bozukluğuna eşlik eder, ancak klinik oftalmopati ötroid graves varlığında da ortaya çıkabilir. Tiroid oftalmopati, otoimmün bir hastalık olup tiroide ve retroorbital dokuya ait ortak bir antijene karşı antikor cevabı oluşmaktadır. Retroorbital dokudaki fibroblastlar bu antijenin primer bölgesi gibi görünmektedir. Otoimmün tiroid hastalığı bulunan kişilerde göz şikayetleri ile sık karşılaşılmakta, ancak olguların çoğunda hafif veya orta şiddette klinik oftalmopati görülmektedir. Az sayıda olguda ise optik nöropati veya kornea perforasyonu neticesinde ciddi görme kaybına neden olabilen ciddi oftalmopati izlenmektedir. Tanı genellikle klinik bulgulara dayanılarak konulur; tiroid fonksiyon testleri, tiroid antikorları ve orbita görüntüleme yöntemleri ise tanıda yardımcıdır. Günümüzde oftalmopati gelişimini engelleyecek bir tedavi yönteminin bulunmaması hastalığın tedavisinde özellikle hafif olgularda semptomatik yaklaşımı gündemde tutmaktadır. Ancak, orta veya ağır TO olgularında birden fazla tıbbi ve/veya cerrahi tedavi gerekebilir. Bu hastaların yakından takip edilmesi ve tedavilerinin doğru sırayla uygulanması çok önemlidir. Bu çalışmada, tiroid oftalmopati tanısı alan ve üçüncü basamak referans merkezi olarak endokrinoloji ve diğer göz kliniklerinden kliniğimize refere edilen olguların takip ve tedavi sonuçlarının tartışılması amaçlandı.Hastaların kayıtları retrospektif olarak incelendi ve EUGOGO kriterlerine göre bilimsel detayların tamamlanabildiği 168 olgunun 306 gözü çalışmaya dahil edildi. Olguların yaş ortalaması 42,3 ± 12,4 yıl idi. Olguların 105'i kadın, 63'ü erkek idi. Olguların %54,2'sinde sigara kullanım öyküsü mevcuttu. Olguların %39,2'sinin birinci veya ikinci derece akrabasında tiroid hastalığı bulunmaktaydı. Tiroid hastalıkları incelendiğinde, 135 olguda (%80,4) graves hastalığı saptanmış olup, kalan 33 olguda diğer tiroid hastalıkları (hashimoto tiroiditi %8,3, multinodüler guatr %8,3 ve tiroid kanseri %3) bulunmaktaydı. Göz tutulum ve tiroid hastalığı süreleri birlikte değerlendirildiğinde, 91 olguda (%54,2) klinik oftalmopati ile tiroid hastalığı tanılarının eş zamanlı olduğu görüldü. Gözlerin %68'inde kapak retraksiyonu, %54,8'inde aşağı bakışta kapak gecikmesi, %6,9'unda lagoftalmus ve %2'sinde pitozis saptandı. Ortalama proptozis ölçümü 20,3 ± 3,2 mm olup, proptosis gözlerin %47'sinde mevcuttu. Gözlerin %32,4'ünde hareket kısıtlılığı görülürken, olguların sadece %7,1'inde manifest kayma (4 hT, 3 ET+hT, 2 ET, 3 XT) tespit edildi. Kompresif optik nöropati %2 oranında saptanırken, ciddi korneal tutulum hiçbir olguda mevcut değildi. Hastalık şiddeti değerlendirildiğinde, 197 gözde (%64,4) hafif, 103 gözde (%33,6) orta-ciddi ve 6 gözde (%2) ise çok ciddi tutulum izlendi. Yüz gözde (%32,6) aktif TO bulguları izlenirken, 206 gözde (%67,4) TO inaktif fazda idi. Hastaların %20'sine (34 olgu) tedavi uygulandı. En çok uygulanan tedavi sistemik steroidler (%12) olup bunu orbita dekompresyonu (%5), orbital radyoterapi (%2) ve topikal guanetidin uygulaması (%1) izledi.Sonuçta, göze yönelik tedaviler hastalığın şiddet ve aktivitesi yanında, hastaların ek sistemik hastalıkları, tedavi uyumu ve endokrinoloji bölümünün önerileri de göz önünde bulundurularak planlanmalıdır. Hastalarda spontan regresyon olabileceği unutulmamalı ve tedavi aşamasında fazla proaktif davranılmamalıdır.Anahtar kelimeler: klinik aktivite skorlaması, orbital dekompresyon, orbital radyoterapi, sigara, tiroid oftalmopati. Thyroid ophthalmopathy, is the most important extra thyroidal finding of Graves disease. Ocular involvement often accompanies with thyroid dysfunction but ophthalmopathy can also occur in the presence of euthyroid Graves.Thyroid ophtalmopathy, is an autoimmune disorder that an antibody response was seen against a common antigen of thyroid gland and retroorbital tissue. Orbital fibroblasts seem to be the primary site of this antigen.Eye problems are common in cases with autoimmune thyroid diseases, but mild or moderate clinical ophthalmopathy is seen mostly. In a few cases there is severe ophthalmopathy that corneal perforation or optic neuropathy leads to severe vision loss. Diagnosis is based on the clinical findings, however thyroid function tests, thyroid autoantibodies and orbital imaging methods are useful.Symptomatic approach is preferred especially in mild cases since there is no treatment modality that can prevent ophtalmopathy development. However, many medical and/or surgical treatments may be necessary in cases with moderate or severe TO. These patients should be followed up frequently and treated in the correct order.The aim of this study was to discuss the follow up and treatment results of cases who were referred to our clinic as the tertiary reference center from endocrinology and other eye clinics.Medical records of the patients were evaluated retrospectively and 306 eyes of 168 patients that scientific details can be completed according to the EUGOGO criteria were included in the study. The mean age of the patients was 42.3 ± 12.4 years. Sixty three men and 105 women participated to the study. Smoking habits were noted in 54.2% of the cases. There was a thyroid disease in the first or second degree relatives in 39,2% of the cases. Graves disease was found in 135 cases (80.4%), the remaining 33 cases had other thyroid diseases (Hashimoto's thyroidits 8.3%, multinodular goiter 8.3% and thyroid cancer 3%). When the durations of eye and thyroid diseases were evaluated together, it was observed that the times of diagnosis for both eye and thyroid diseases were simultaneous in 54,2% of the cases. There was lid retraction in 68%, lid lag in 54.8%, lagophtalmus in 6.9% and pitosis in 2% of the eyes. The mean proptosis was 20.3 ± 3.2 mm and proptosis was present in 47% of the eyes. Movement was limited in 32.4% of the eyes, but manifest deviation (4 ht, 3 hT+ET, 2 ET, 3 XT) was detected only in 7.1% of the cases.
