Ultra-wide-field fundus photography compared to ophthalmoscopy in diagnosing and classifying major retinal diseases.

To analyze the performance of ultra-wide-field (UWF) fundus photography compared with ophthalmoscopy in identifying and classifying retinal diseases. Patients examined for presumed major retinal disorders were consecutively enrolled. Each patient underwent indirect ophthalmoscopic evaluation, with scleral depression and/or fundus biomicroscopy, when clinically indicated, and mydriatic UWF fundus imaging by means of CLARUS 500™ fundus camera. Each eye was classified by a clinical grader and two image graders in the following groups: normal retina, diabetic retinopathy, vascular abnormalities, macular degenerations and dystrophies, retinal and choroidal tumors, peripheral degenerative lesions and retinal detachment and myopic alterations. 7024 eyes of new patients were included. The inter-grader agreement for images classification was perfect (kappa = 0.998, 95% Confidence Interval (95%CI) = 0.997-0.999), as the two methods concordance for retinal diseases diagnosis (kappa = 0.997, 95%CI = 0.996-0.999) without statistically significant difference. UWF fundus imaging might be an alternative to ophthalmoscopy, since it allows to accurately classify major retinal diseases, widening the range of disorders possibly diagnosed with teleophthalmology. Although the clinician should be aware of the possibility that a minority of the most peripheral lesions may be not entirely visualized, it might be considered a first line diagnostic modality, in the context of a full ophthalmological examination.

Descriptive epidemiology of malignant mucosal and uveal melanomas and adnexal skin carcinomas in Europe.

This work provides descriptive epidemiological data of malignant mucosal and uveal melanomas and adnexal skin carcinomas in Europe as defined as in the RARECARE project. We analysed 8669 incident cases registered in the period 1995-2002 by 76 population-based cancer registries (CRs), and followed up for vital status to 31st December 2003. Age-standardised incidence to the European standard population was obtained restricting the analysis to 8416 cancer cases collected by 64 not specialised CRs or with information available only for some anatomical sites. Period survival rates at 2000-2002 were estimated on 45 CRs data. Twenty-two CRs which covered the period 1988-2002 were analysed to obtain the 15-year prevalence (1st January 2003 as reference date). Complete prevalence was calculated by using the completeness index method which estimates surviving cases diagnosed prior to 1988 ('unobserved' prevalence). The expected number of new cases per year and of prevalent cases in Europe was then obtained multiplying the crude incidence and complete prevalence rates to the European population at 2008. We estimated 5204 new cases per year (10.5 per million) to occur in Europe, of which 48.7% were melanomas of uvea, 24.8% melanomas of mucosa and 26.5% adnexal carcinomas of the skin. Five-year relative survival was 40.6% and 68.9% for mucosal and uveal melanomas, respectively. Adnexal skin carcinomas showed a good prognosis with a survival of 87.7% 5 years after diagnosis. Northern Europe, United Kingdom (UK) and Ireland showed the highest 5-year survival rate for uveal melanomas (72.6% and 73.4%), while Southern Europe showed the lowest rate (63.7%). More than 50,000 persons with a past diagnosis of one of these rare cancers were estimated to be alive at 2008 in Europe, most of them (58.8%, n=29,676) being patients with uveal melanoma. Due to the good prognosis and high incidence of uveal melanomas, these malignancies are highly represented among the long-term survivors of the studied rare cancer types. Therefore, maximising quality of life is particularly important in treatment of uveal melanoma. As regards mucosal melanomas, the centralisation of treatment to a select number of specialist centres as well as the establishment of expert pathology panels should be promoted. The geographical differences in incidence and survival should be further investigated analysing the centre of treatment, the stage at diagnosis and the treatment.

In vivo confocal microscopy of ocular surface squamous neoplasia.

PURPOSE: To analyse in vivo structural and cellular features of ocular surface squamous neoplasia using clinical confocal microscopy. METHODS: Ten consecutive cases of untreated ocular surface squamous neoplasia were in vivo investigated using clinical confocal microscopy (ConfoScan4, Nidek Co. Ltd, Gamagori, Japan) with a × 40 surface non-contact objective lens. Confocal microscopy images were compared with cytologic samples obtained by scraping technique. RESULTS: Confocal microscopy examination revealed large areas of superficial cells debris and/or keratin debris accompanied by syncytial-like groupings, loss of the normal structure of the conjunctival epithelium and or of the corneal basal epithelium layer, papillomatous organization, large fibrovascular structures, and fine vessels perpendicular to the tumour surface. Sub-epithelial (pre-Bowman) space involvement was documented in four cases (50%). Irregular healthy tissue infiltration at the lateral edge of the lesion was documented in two cases (20%) whereas abrupt demarcation between neoplastic cells and normal epithelium was documented in eight cases (80%). In vivo cyto-morphologic study using clinical confocal microscopy showed cellular anisocytosis, pleocytosis, and anisonucleosis, enlarged nuclei with high nuclear to cytoplasmic ratio, high reflective cytoplasm and indistinct cytoplasmic borders in all cases (100%) . CONCLUSION: CCM appears to be a promising and non-invasive method for in vivo structural and cellular analysis of OSSN.

Long-term follow-up with optical coherence tomography and microperimetry in eyes with metamorphopsia after macula-off retinal detachment repair.

PURPOSE: to report the long-term sequential morphological and functional results in eyes with metamorphopsia after retinal detachment (RD) repair. PATIENTS AND METHODS: in six eyes of six patients aged 58.7 ± 11.0 years with metamorphopsia after successful buckling surgery for macula-off RD, best-corrected visual acuity (BCVA), fundus biomicroscopy, Amsler grid test, time-domain optical coherence tomography (TD-OCT) and central 12° microperimetry (MP-1) were performed at months 1, 3, 6, 12, and 18. At 5 to 6 years after surgery all patients underwent also spectral domain (SD)-OCT. RESULTS: three eyes slowly recovered pre-RD BCVA. In the remaining three eyes-with good final BCVA-the interrupted junction line between photoreceptor cell inner and outer segments (IS/OS) was progressively less evident after RD surgery; and the external limiting membrane was preserved on SD-OCT examination. In all eyes post-operative metamorphopsia faded with time, but fully disappeared in 6 years only in two eyes without photoreceptor abnormalities. One of the two eyes with subretinal fluid up to 6 months and IS/OS disruption had central dense scotoma with relatively unstable fixation on MP-1 and persistent metamorphopsia. Macular sensitivity (MS) increased from 9.7 ± 7.1 at month 1 to 13.5 ± 5.6 dB at the final check, and was weakly (r=0.33) correlated with post-operative BCVA and OCT abnormalities. CONCLUSION: long-standing metamorphopsia can occur after successful macula-off RD repair even without detectable photoreceptor disruption on OCT. Post-operative BCVA recovery weakly correlates with increasing MS, and late restoration of the photoreceptor layer may be observed.

In vivo detection of monosomy 3 in eyes with medium-sized uveal melanoma using transscleral fine needle aspiration biopsy.

PURPOSE: Cytogenetic prognostication of choroidal melanoma, particularly monosomy 3 detections, is limited to enucleated eyes or resected tumors. The authors developed an in vivo technique to detect monosomy 3 using transscleral fine needle aspiration biopsy (FNAB). METHODS: Eight eyes with medium-sized choroidal melanoma were included in this prospective study. A 25-gauge transscleral FNAB was performed during surgical procedure for brachytherapy, just before applying the radioactive plaque over the tumor base. Sampled material underwent fluorescence in situ hybridization (FISH) with centromeric probes for chromosome 3. Follow-up was >12 months. RESULTS: Transscleral FNAB yielded sufficient material in 7 of 8 eyes (87.5 %). Five of seven eyes had monosomy 3. No early or late complications were detected. CONCLUSIONS: This study demonstrates that medium choroidal melanomas may be safely sampled by intraoperative transscleral FNAB to detect monosomy 3 in vivo.

Reconstruction of conjunctiva with amniotic membrane after excision of large conjunctival melanoma: a long-term study.

PURPOSE: To evaluate, on a long- term basis, the role of amniotic membrane in the reconstruction of large conjunctival defects after excision of large conjunctival melanoma. METHODS: Four consecutive patients with diffuse conjunctival melanoma involving both bulbar and palpebral conjunctiva were studied. Conjunctival melanoma was completely excised (with wide clinically disease-free margins) and amniotic membrane immediately sutured to the surrounding conjunctiva and sclera to cover the conjunctival defect. Minimum follow-up was 48 months. RESULTS: Successful conjunctival surface reconstruction and physiologic fornical depth were achieved in all patients within 6 weeks. No recurrence of primary melanoma was observed during long-term follow-up. CONCLUSIONS: Amniotic membrane transplantation is an effective alternative in ocular surface repairing surgery after removal of large conjunctival tumors.

Treatment of conjunctival squamous cell carcinoma with topical 5-fluorouracil.

AIM: To evaluate the efficacy of topical 5-fluorouracil (5-FU) alone, without concurrent surgery or radiotherapy, for the treatment of conjunctival squamous cell carcinoma. METHODS: Eight patients affected by conjunctival squamous cell carcinoma (three recurrent cases, three incompletely excised, and two untreated cases) were treated with 1% 5-FU eye drops. Topical 1% 5-FU was administered four times daily for 4 weeks (one course). Clinical examination (biomicroscopy and photography) and morphological evaluation of conjunctival cytological specimens were used to monitor the efficacy of local chemotherapy, side effects, and recurrences. RESULTS: All patients showed clinical regression of conjunctival carcinoma after topical 1% 5-FU treatment. Neoplastic conjunctiva was completely replaced by normal epithelium within 3 months. Mean follow up was 27 months. One patient needed two courses of local chemotherapy for recurrent disease. An acute transient toxic keratoconjunctivitis was observed in all treated cases; it was easily controlled with topical therapy. No long term side effects were found. CONCLUSIONS: Topical 1% 5-FU is effective in the treatment of recurrent, incompletely excised, and selected untreated conjunctival squamous cell carcinomas. Topical 1% 5-FU has no major complications. This study suggests that topical conjunctival chemotherapy with 1% 5-FU may be useful, at least as adjunctive therapy, in the treatment of conjunctival squamous cell carcinoma.

Isolated brain metastasis of malignant choroidal melanoma 27 years after enucleation.

Choroidal melanoma primarily metastasizes to the liver. Isolated extrahepatic metastases have rarely been reported and they generally resulted in death within 6 months. We describe a patient who developed an isolated brain metastasis 27 years after his left eye was enucleated for choroidal melanoma. The metastasis was successfully treated with surgery and radiotherapy. The patient is alive and disease free 3 years after treatment of the metastasis. Posterior location and other clinical and morphologic characteristics of primary choroidal melanoma could explain the unusually long latency of this solitary extrahepatic metastatic disease. Lifelong surveillance to detect early signs of metastasis is mandatory for any patient treated for choroidal melanoma.

The effect of external eye irradiation on choroidal circulation.

BACKGROUND: The effect of external beam radiation therapy (teletherapy) on the choroidal circulation is poorly known. Eyes irradiated with teletherapy represent a good model to study, without confounding factors, the pathophysiologic and clinical aspects of radiation-induced chorioretinal damage. This study used fluorescein and indocyanine green choroidal angiography to investigate the late effects of external eye irradiation on the choroidal circulation. METHODS: Fluorescein angiography and indocyanine green choroidal videoangiography were performed on patients with radiation retinopathy because of external eye irradiation for orbital and paranasal sinus malignancies. Patients were divided into two groups according to the treatment field (anterior unilateral or bilateral). RESULTS: Indocyanine green angiograms showed areas of choriocapillaris hypoperfusion in all eyes-unilateral or bilateral irradiation-affected by radiation retinopathy. Late indocyanine green choroidal staining was found in five eyes (28%) of the patients who received unilateral anterior irradiation. In the same group, nine eyes (52%) had signs of choroidal precapillary occlusion and four eyes (23%) had rubeosis iridis without retinal neovascularization. One case of subfoveal choroidal neovascularization was documented in the bilateral irradiation group. CONCLUSIONS: Radiation side effects are not limited to the retinal vessels but also involve choroidal circulation. The damage to the choroid is primarily vascular, and its clinical aspects depend on the treatment fields. Anterior irradiation may be a critical factor for the appearance of unusual rubeosis iridis and neovascular glaucoma.

Orbital ectopic lacrimal gland tissue simulating a neoplasm. Report of a case with fine needle aspiration biopsy diagnosis.

A case occurred of sclerosing chronic dacryoadenitis in lobules of ectopic lacrimal gland tissue diagnosed by fine needle aspiration biopsy performed under computed tomographic guidance. This choristomatous lesion caused unilateral proptosis and clinically simulated a neoplasm. This is the first report of cytologic diagnosis of orbital ectopic lacrimal gland tissue using fine needle aspiration biopsy. The potential hazard of regarding glandular inclusions derived from inadvertent use of a needle on a normal lacrimal gland or glands as indicating metastatic neoplasms is stressed.

Anton (von) Rosas (1791-1855): on the occasion of the bicentennial of his birth. Part II. A survey of his scientific works with special emphasis on specific topics.

The author outlines the scientific works of Anton (von) Rosas (1791-1855), professor of ophthalmology in Padua and Vienna. Rosas' scientific opinions are compared with those of his teacher (G. J. Beer) and contemporaries. Three topics of medical and surgical ophthalmology have been analyzed in detail: epidemic-contagious ophthalmia of the army, cataract and artificial pupil. Rosas appears as a protagonist of the ophthalmologic culture of his time.

Effects of ionizing radiation on human conjunctival epithelial cells: a clinical and cytologic study.

In order to identify early and late modifications induced by ionizing radiation on the conjunctival surface, we studied 10 patients irradiated for paranasal sinus tumors. A clinical and morphological study of conjunctival epithelium (using an impression cytology technique) was performed; 5 patients were examined during and the others after treatment. Actinic conjunctivitis and keratitis, observed during treatment, reappeared within a few months after the end of radiotherapy. At a threshold dose of 25 Gy, chronic nuclear changes and cellular surface disorganization of the conjunctival epithelium were found--these progressed and persisted. Our data support the importance of careful monitoring of such irradiated patients and the benefit of planning a prospective clinical study to evaluate the effects of available drugs (all-trans retinoic acid) in the treatment of these lesions.

The epidemiology and prevalence of diabetic retinopathy in the Veneto region of north east Italy. Veneto Group for Diabetic Retinopathy.

The prevalence of diabetic retinopathy and its relationship to a number of risk factors were examined in a population-based study in the Veneto region of North East Italy. Of 1321 diabetic patients selected, 98% attended for examination. Prevalence of diabetic retinopathy was 26.2% (24.4% background and 1.8% proliferative). The prevalence of retinopathy was significantly related (p less than 0.01) to the duration of diabetes (17.3% for less than 5 years; 60.8% for greater than 20 years). Proliferative retinopathy was much more prevalent after 20 years of diabetes. After 10 years most proliferative retinopathy was found in Type 1 diabetic patients, but before 10 years from diagnosis it was most prevalent in Type 2 diabetes. The prevalence of retinopathy was significantly related (p less than 0.001) to the type of diabetes and was found predominantly in Type 1 (46.2%) and insulin-treated Type 2 (45.9%) subjects and to a lesser degree in non-insulin-treated patients (24.6%). The prevalence of retinopathy was significantly related to both fasting and post-prandial blood glucose levels (p less than 0.001), blood urea nitrogen (p less than 0.05), and systolic (p less than 0.001) and diastolic (p less than 0.01) blood pressure. No significant differences were found in the prevalence of total or proliferative retinopathy between males and females. No significant relationships were found with family history of diabetes, alcohol intake, smoking habits, cholesterol, triglycerides, and serum uric acid.

[Sorsby's pseudo-inflammatory macular dystrophy: laser treatment]. / Dystrophie maculaire pseudo-inflammatoire de Sorsby: essai de traitement par le laser.

In 1949, Sorsby described a familial fundus disease with progressive visual loss and bilateral hemorrhages and exudates of the posterior pole. The dystrophy, whose inheritance was apparently autosomal dominant, was called pseudo-inflammatory macular dystrophy because of extensive macular lesions that could suggest a post-inflammatory change. The ophthalmoscopic signs include the presence of diffuse drusen-like deposits with extensive changes of retinal pigment epithelium and focal atrophy of the choriocapillaris, particularly in the posterior pole. Some eyes grow subretinal neovascularization, which appears associated to retinal edema, deep hemorrhages and hard exudates. These cases ultimately result in a disciform macular scar. Atrophy of peripheral fundus is typical of advanced stages. We present the case of three sisters whose fundus lesions resembled Sorsby's pseudo-inflammatory macular dystrophy. In two of them, where there was a great suspicion of macular subretinal neovascularization, the laser treatment seemed to positively condition the course of the disease. In our opinion, even though a generalized atrophy of the choroid and retina cannot probably be avoidable, laser treatment can delay the loss of central vision, by blocking the capillaries from leaking, thus preventing secondary destruction from bleeding and fibrosis.

Juvenile pilocytic astrocytoma of the optic nerve diagnosed by fine needle aspiration biopsy.

Fine needle aspiration biopsy of an orbital mass was performed under CT guidance in a nine-year-old boy presenting with rapidly increasing proptosis of the right eye with lateral displacement and no light perception. The cytologic findings consisted of bipolar astrocytes with cytoplasmic fibrillated processes intermingled with Rosenthal fibers. A cytologic diagnosis of juvenile pilocytic astrocytoma was advanced; this was confirmed by subsequent histologic study of the surgical specimen. The differential diagnosis among juvenile pilocytic astrocytoma, neurilemmoma and meningioma of the optic nerve are discussed.

Retinopathy following radiation therapy of paranasal sinus and nasopharyngeal carcinoma.

Radiation retinopathy is a complication of the therapeutic irradiation of orbital and periorbital structures. The authors studied two groups of patients who had orbital (group 1) and periorbital (group 2) external irradiation. Radiation retinopathy occurred in 63.6% of patients in group 1 and 36.3% group 2. Retinal radiation damage showed a different clinical evaluation in the two groups, appearing earlier (mean, 11 versus 55 months) and with greater involvement of the peripheral retina in group 1 (with three cases of neovascular glaucoma). This study demonstrates that radiation retinopathy occurs in a significant number of cases when the eye is not totally involved in the irradiation field and shows at least two different clinical aspects in relation to the radiation treatment. It also suggests that portal design and choroidal circulation damage may represent important factors in the development of radiation retinopathy.

Fine needle aspiration biopsy in ophthalmology.

When noninvasive techniques fail to confirm or rule out the suspicion of a malignant lesion, fine needle aspiration biopsy may provide an efficient, economical and relatively safe method of obtaining material for cytological study. The technique may also be valuable for intraoperative morphological evaluation. Traumatic complications produced by fine (21-25 gauge) needles are infrequent and almost never serious, and concerns about tumor seeding through the procedure have been largely dispelled by recent studies. Reliable results require a high level of skill in performing the aspiration procedure and in cytologically examining the small amount of material obtained. The authors review the history, applications, techniques and complications of fine needle aspiration biopsy, presenting guidelines for and illustrations of its use in specific ophthalmic situations.
