Abstract
PURPOSE Despite the use of perioperative anxiolytics and pain medication, surgery can be a stressful and painful experience. Providing patients with distractions using video and/or audio tools in addition to medication may be helpful. To date, no studies have compared different distraction modalities in a same-day surgical setting in adults. This study aims to determine whether audio-visual distraction with video glasses (AVD) is more effective in reducing anxiety and pain compared to audio distraction (AD) in conscious patients undergoing orthopaedic surgery. It was hypothesised that AVD, being the more immersive modality, would be more effective than AD on the outcome parameters. METHODS Fifty patients undergoing orthopaedic surgery with local and/or regional anaesthesia in a clinical day-care setting were randomly assigned to receive either fixed-scenery AVD or patient-choice AD with music. Primary outcome was anxiety, as measured by the Dutch version of the Spielberger State-Trait Anxiety Inventory-6 (STAI-6) prior to and 15 min after the intervention. Secondary outcomes were pain (Numeric Rating Scale Pain [NRS-P]), systolic and diastolic blood pressure, heart rate and patient satisfaction. RESULTS Within each group, there was a significant reduction in anxiety (p = 0.028 for AVD, p < 0.001 for AD). In contrast to our hypothesis, listening to music without watching a video (AD group) reduced anxiety significantly more than experiencing full AVD (p = 0.018). The mean pain score did not change significantly within either user group, nor did pain scores differ between user groups. CONCLUSION In conscious patients undergoing surgery, watching a movie (using video glasses and a headphone set) and listening to music (using only a headphone set) are able to significantly reduce anxiety. AVD, although believed to provide higher levels of distraction, did not prove to be superior to AD. The clinical relevance of this study highlights the potential benefits of AVD or AD modalities in improving the surgical experience for conscious patients. Further research is required to examine the influence of freedom of choice in content on the aforementioned outcomes. To estimate the true value of higher immersion levels, different distraction modalities (e.g. AVD versus virtual reality) featuring the exact same scenery or content need to be compared. LEVEL OF EVIDENCE Level I.

Abstract
Background It is suggested that stress related to infertility causes marriage conflicts and decreases in the frequency of sexual intercourse. Aim This study aimed to explore the experiences of the sexuality of infertile women. Patients and Methods A phenomenological design was used in this study. We conducted face-to-face, semistructured, in-depth interviews with 11 infertile women. The interviews were audio-recorded, and a thematic approach was used to assess the data. Results The average age of the women was 33.05 ± 3.40 years, and their age of first sexual intercourse was 23.0 ± 2.8 years and all of them are legally married. The durations of experiencing the problem of infertility were as follows; 3-5 years in 33%, 6-10 years in 27%, and 11 years and above in 38%. According to interpretative phenomenological analysis, two main themes emerge. Two main themes were determined: Perception of Sexuality and Sexual Problems. The results show that infertile women have a higher risk for sexual dysfunction than fertile women. Conclusion These findings suggest that the diagnosis of infertility is an important factor in assessing the differences in the sexual satisfaction of women. In infertility counseling, health professionals must explain the gender differences. Also, infertile couples must encourage to share each other's feelings and this may help couples to cope with the communication problems they may experience.

Abstract
AIM Although the bifrontal approach used to be recommended for large olfactory groove meningioma (OGM), recent studies showed that large OGMs can also be resected safely via unilateral approaches. The present study aimed to discuss reasons for preferring a unilateral frontotemporal approach (UFTA), and the technical nuances and results of the UFTA, based on 18 cases. MATERIAL AND METHODS The clinical and surgical data of patients who had been operated on for large (4-6cm) or giant (>6cm) OGM via a UFTA between 2011 and 2018 were retrospectively collected. RESULTS In all, 18 patients were included. All tumors were compatible with a diagnosis of OGM in the light of peri-operative examinations. 11 cases (61%) were large and 7 (39%) giant OGM; mean diameter was 6.1cm (range, 4-10cm). Resection extent was Simpson grade II in 14 cases (78%), grade III in 1 (5%), and grade IV in 3 (17%). Sixteen cases (89%) had no peri-operative complications, while 2 patients (11%) showed cerebrospinal fluid leakage and hemorrhagic deposition in the surgical area. There were no new neurological deficits nor deaths. CONCLUSION The UFTA for OGM is a relatively safe and effective approach, ensuring a high total removal rate with low mortality and morbidity. This study, with a reasonable number of patients, is one of the few in the literature on the outcome of this approach.

Abstract
Glioblastoma (GBM) is the most prevalent and deadliest subtype of glioma. Despite current innovations in existing therapeutic modalities, GBM remains incurable, and alternative therapies are required. Previously, we demonstrated that Olea europaea leaf extract (OLE) kills GBM cells by modulating miR-181b, miR-137, miR-153 and Let-7d expression. However, although oleuropein (OL) is the main compound in OLE, its role in the antitumour effect of OLE remains unknown. This study determined the effect of OL on GBM cell line T98G and compared the results with our previous findings regarding the effect of OLE on the same cell line. The antiproliferative activity of OL and its effect on temozolomide (TMZ) response were tested inT98G cells using WST-1 assay. OL inhibition was evaluated using one-way analysis of variance with Tukey's post hoc test. The effect of OL on miR-181b, miR-137, miR-153 and Let-7d expression was assessed using quantitative reverse transcription polymerase chain reaction. Fold differences in expression between untreated, OL or OL + TMZ-treated samples were calculated using 2-ΔCt method. Significance was evaluated using an independent sample t-test. Treatment with 277.5 and 555 µM OL resulted in 39.51% and 75.40% reductions in T98G cells within 24 h. Coadministration of 325 µM TMZ and 277.5 or 555 µM, OL caused 2.08- and 2.83-fold increases, respectively, in the therapeutic effect of TMZ. OL + TMZ significantly increased microRNA expression, particularly Let-7d, than OLE. In conclusion, OL has an antitumour effect on GBM cells mainly via regulation of Let-7d expression. The present results also indicate other minor compounds in OLE play important anticancer roles.

Abstract
INTRODUCTION External radiotherapy is one of the main treatment modalities for a variety of malignancies. However, the lower gastrointestinal tract is sensitive to the ionizing radiation. Hyperbaric oxygen treatment (HOT) has been suggested as a viable treatment for refractory radiation colitis, but the effect of S-Methylisothiourea (SMT) in the radiation colitis have not reported. To investigate the effect of SMT, HOT and the combination of both in an acute radiation-induced enterocolitis model. METHODS Sixty Sprague-Dawley rats were divided randomly into five equal groups. A single dose of gamma irradiation (25 Gy) was administered through the colorectal region to anesthetized rats. In the control group, we applied 2 ml of saline solution intraperitoneally for five days. In the HOT group, 100-per-cent oxygen at 2.5 atm pressure was applied for five days. In the SMT group, 10 mg/kg/day of SMT was applied intraperitoneally for five days. In the HOT+SMT group, HOT and SMT were both applied in the same dosages as in the preceding two groups. At the end of five days, the rats were sacrificed and colon samples were collected for histological grading. Blood samples were collected to test for : tumor necrosis factor-α (TNF-α), interleukin-10 (IL-10), IL-1β, transforming growth factor-β (TGF-β) and intercellular adhesion molecule-1 (ICAM-1) mRNA. RESULTS The TNF-α, IL-1β, IL-10 and TGF-β levels were reduced by SMT, HOT and HOT+SMT applications (p < 0.05). However ICAM-1 mRNA levels were not significantly lower (p:0.19). The microscopic scores differed significantly between the SMT, HOT and HOT+SMT groups and the control group. There was significant improvement histologically, especially in the HOT+SMT group. When we compared the weight of the rats before and after the study, weight loss was significantly lower in the SMT, HOT and HOT+SMT groups compared with the control group (p < 0.05). CONCLUSION HOT and SMT together were significantly more effective in preventing weight loss and in reducing inflammation and the severity of colitis histology when compared with HOT and SMT separately.

Abstract
AIM Spina bifida (SB) is a congenital deformity that is frequently seen in infancy. Surgical treatment and clinical follow-up of patients with the diagnosis of SB are important to provide education to the patients and their relatives, to increase patient survival, to ensure that they have a more comfortable life. Neuro-urological problems are highly important for the patients in terms of both social and medical. MATERIALS AND METHODS The medical records of patients who underwent surgery for SB and tethered cord syndrome at our clinic in the past year were retrospectively evaluated. The results of urodynamic studies of the patients were evaluated. The results of patients who underwent control urodynamic studies during the follow-up period were compared with the previous results, and their clinical courses were determined. RESULTS The most frequent urodynamic changes in patients were hyperactive detrusor activity and detrusor sphincter dyssynergy preoperatively. CONCLUSION A significant improvement was observed when the results of postoperative urodynamic studies were evaluated in patients who underwent surgery for tethered cord.

Abstract
OBJECTIVE Thyroid fine needle aspiration biopsy (TFNAB) is the gold standard in the differential diagnosis of the thyroid nodules. In general, no analgesia is needed before this procedure. However, it is usually believed that the patients may be more comfortable if the procedure is performed under local anaesthetics. In this study, we examined the impact of the use of dermal anaesthetic on the patient's level of discomfort during palpation-guided TFNAB. METHODS Fifty female patients with nodular goitre were enrolled in this study. Patients were randomised into two groups: a placebo cream was applied to group 1 patients (25 females; mean age 47.45 +/- 11.61 years), and local anaesthesia (EMLA 5% cream) was applied to group 2 patients (25 females; mean age 50.89 +/- 12.01 years) approximately 1 h before TFNAB. All patients were asked to mark the pain they felt during the TFNAB on Visual Analogue Scale. RESULTS The pain scores during TFNAB were 27.73 +/- 20.01 mm and 24.79 +/- 21.98 mm in the placebo group and in the EMLA group respectively. There was no significant difference between the groups (p = 0.496). CONCLUSIONS Topical anaesthesia before palpation-guided TFNAB provides no benefit.

Abstract
OBJECTIVE CA 72-4 is one of the blood group carbohydrate antigens which can be used as a tumour marker in ovarian, pancreatic and gastrointestinal carcinomas. It can also be elevated in various benign conditions including pancreatitis. Diabetes mellitus is a chronic disorder related with the pancreas. In this study, we investigated CA 72-4 levels in patients with type 2 diabetes and its relation to the metabolic status. METHODS Sixty-nine patients with type 2 diabetes mellitus (female/male = 40/29) and 60 healthy subjects (female/male = 35/25) participated in this study. The levels of serum CA 72-4 were measured and faecal occult blood tests (following 3 days of white diet were obtained for three consecutive days) were performed in all patients. Patients had a pathological finding for any of these two parameters were further investigated with upper gastrointestinal endoscopy, colonoscopy and computerised tomography. RESULTS The mean levels of CA 72-4 was 1.89 +/- 2.61 U/ml in the study group and 1.4 +/- 0.98 U/ml in the control group (p > 0.05). There was no association between CA 72-4 levels and age and sex of the patients, duration of diabetes, body mass index, biochemical indicators of metabolic control (the levels of HbA(1c), fasting and postprandial glucose, serum lipids), the presence of microvascular complications (retinopathy, nephropathy, neuropathy) or treatment modalities. CONCLUSIONS Elevated levels of CA 72-4 in diabetic patients are not related to diabetes and it should be interpreted as evaluated in a non-diabetic patient.

Abstract
PURPOSE To report a case of circumscribed choroidal hemangioma (CCH) that responded to photodynamic therapy (PDT) but 3 years later developed polypoidal choroidal vasculopathy (PCV) with exudative retinopathy. METHODS Case report. RESULTS A 59-year-old woman with a juxtapapillary CCH in her left eye was treated with a single 83-second, 7.5 mm PDT laser spot at 689 nm (50 J/cm2) 15 minutes after the injection of intravenous verteporfin (6 mg/m2). Three years later, the patient presented with photopsia in her left eye. Fundus examination of the left eye showed CCH regressed completely to a flat atrophic scar. There was diffuse macular edema and exudative retinopathy along the inferotemporal vascular arcade. On indocyanine green angiography, there were hyperfluorescent dilated choroidal vessels inferior to the foveola with late staining and leakage consistent with PCV. Hypofluorescence superior and nasal to the optic disc at the site of the treated hemangioma, consistent with choroidal ischemia, was observed. She was treated with 1.25 mg (0.05 cc) intravitreal bevacizumab. After 21 months of follow-up, the exudative retinopathy and macular edema completely regressed. CONCLUSIONS PDT is an effective treatment for CCH. Side effects of PDT for CCH are rare but include PCV.

Abstract
AIM This study was designed in order to examine the relationship between Calpain 10 [single-nucleotide polymorphism (SNP) 19,43,44,63] gene polymorphisms and clinical and hormonal characteristics in women with polycystic ovary syndrome (PCOS). MATERIALS AND METHODS One hundred and seven patients with PCOS and 114 healthy subjects were included in this study. Serum levels of sex steroids were measured for each individual. Insulin resistance (IR) was evaluated by the homeostasis model assessment (HOMA) and quantitative insulin-sensitivity check index (QUICKI) methods. Insulin and glucose responses to the oral glucose tolerance test (OGTT) were analyzed by calculating the areas under the curve for insulin (AUCI) and glucose by the trapezoidal methods.We used PCR and restriction fragment length polymorphism technique to examine Calpain 10 SNP 19, 43, 44, and 63 polymorphisms. RESULTS Allele distribution of Calpain 10 SNP 44 gene polymorphism was observed as significantly different between the groups. Calpain 10 SNP 44 TC genotype was found to be increased in PCOS subjects (69.15%) compared to the control subjects (50%). However, when compared to control subjects, patients with PCOS had similar Calpain 10 SNP 19, Calpain 10 SNP 43, and SNP 63 gene polymorphisms. When compared with normal Calpain 10 gene SNP 44 allele in PCOS subjects, subjects with PCOS having Calpain 10 gene SNP 44 allele polymorphism had higher free testosterone, androstenedione, DHEA-S, and fasting insulin levels. Also, PCOS women with Calpain 10 gene SNP 44 allele polymorphism had high Ferriman-Gallwey (F-G) score, acne, prevalence of menstrual disturbances, waist-hip ratio, HOMA-IR, AUCI levels and low QUICKI levels. CONCLUSION The findings show that Calpain 10 gene SNP 44 allele polymorphism may have a role in PCOS pathogenesis. However, larger-scale studies are needed in this field.

Abstract
PURPOSE To review the clinical presentation, histopathologic analysis, management, and ocular and systemic outcome of rhabdomyosarcoma affecting the ocular region. DESIGN Retrospective, noncomparative, consecutive, interventional case series. PARTICIPANTS Thirty-three consecutive patients with primary ophthalmic involvement of rhabdomyosarcoma from a single tertiary care center specializing in ocular oncology. MAIN OUTCOME MEASURES Final visual acuity, treatment complications, local recurrence, and distant metastasis. RESULTS The mean age at presentation was 10 years (median, 7 years; range, 1 month-68 years). At presentation, 8 patients (24%) were older than age 10 years and 4 patients (12%) were older than 20 years. The rhabdomyosarcoma was primarily located in the orbit in 25 cases (76%), conjunctiva in 4 cases (12%), eyelid in 1 case (3%), and uveal tract in 3 cases (9%). Symptoms or signs related to the tumor were present for a mean of 5 weeks and included proptosis in 10 patients (30%), eyelid swelling in 7 patients (21%), and blepharoptosis in 6 patients (18%). The initial diagnosis before referral to us included rhabdomyosarcoma in 8 cases (24%), conjunctivitis in 5 cases (15%), orbital or preseptal cellulitis in 5 cases (15%), idiopathic orbital inflammatory pseudotumor in 4 cases (12%), and others. Using the Intergroup Rhabdomyosarcoma Study Group staging and treatment protocols, the tumor was classified as group I in 4 cases (12%), group II in 12 cases (36%), group III in 16 cases (48%), and group IV in 1 case (3%). Treatment included surgical debulking and various regimens of chemotherapy and radiotherapy for the periocular tumors and enucleation for the three intraocular tumors. Local tumor recurrence was detected in 6 patients (18%). Orbital exenteration was necessary for tumor recurrence in 2 cases (6%). Long-term visual outcome of the 28 patients who maintained their globe was 20/20 to 20/40 in 11 patients (39%), 20/50 to 20/100 in 5 patients (18%), and 20/200 to no light perception in 12 patients (43%). Regional lymph node metastasis was detected in 2 patients (6%), one at initial visit and one after therapy. Distant metastasis occurred in 2 patients (6%), one detected at initial visit and one after therapy. With mean follow-up of 8.3 years, tumor-related death occurred in 1 patient (3%). CONCLUSIONS Rhabdomyosarcoma can present in the orbit, eyelid, conjunctiva, and uveal tract. After treatment, local tumor recurrence occurs in 18%, metastasis in 6%, and death in 3%.

Abstract
PURPOSE To review the clinical features and management of circumscribed choroidal hemangioma and determine factors predictive of poor visual outcome. DESIGN Retrospective consecutive noncomparative interventional case series. PARTICIPANTS Two hundred consecutive patients with circumscribed choroidal hemangioma. MAIN OUTCOME MEASURES The main outcome measures were analyzed in 155 patients with follow-up of at least 3 months and included complete resolution of subretinal fluid, worsening of visual acuity (more than 2 Snellen lines), and poor final visual acuity (20/200 or worse). RESULTS The patients were seen at a mean age of 45 years with symptoms of decreased visual acuity (81%), visual field defect (7%), metamorphopsia (3%), floaters (2%), progressive hypermetropia (1%), photopsia (1%), pain (1%), and no symptoms (6%). The referring diagnoses were choroidal hemangioma (29%), choroidal melanoma (29%), choroidal metastasis (9%), retinal detachment (6%), central serous chorioretinopathy (5%), and others. The tumor had a median base of 6.0 mm and median thickness of 3.0 mm. Secondary retinal detachment in the foveal region was present in 81% of the patients. Initial treatment included observation (51%), laser photocoagulation (44%), plaque radiotherapy (4%), external beam radiotherapy (1%), surgical repair of retinal detachment (1%), and enucleation for painful neovascular glaucoma (1%). Kaplan-Meier estimates revealed complete resolution of subretinal fluid in 60% patients at 5 years and 76% patients at 10 years follow-up. By multivariable analysis, clinical factors predictive of complete resolution of subretinal fluid included shorter duration of symptoms (P = 0.03) and inferior quadrant location of tumor (P = 0.001). At initial presentation, 82 of 155 (53%) patients had poor visual acuity (20/200 or worse), and 73 of 155 (47%) patients had good to moderate visual acuity (20/100 or better). Of those 82 patients with poor initial vision, poor final vision was found in 54% at 5 years and 80% at 10 years. Of the 73 patients with good to moderate initial vision, poor final vision was found in 12% at 5 years and 43% at 10 years. By multivariable analysis, clinical factors predictive of poor final visual acuity included poor initial visual acuity (P < 0.001), failure of previous laser photocoagulation before referral (P = 0.01), and tumor management with observation after referral (P = 0.02). Worsening of visual acuity (by more than 2 Snellen lines) was observed in 8% at 5 years and 28% at 10 years of those 82 patients who were initially seen with poor vision. Worsening of visual acuity was found in 10% at 5 years and 30% at 10 years of those 73 patients who initially were seen with good to moderate vision. CONCLUSIONS Circumscribed choroidal hemangioma is a rare intraocular tumor. In 38% of cases, this tumor is initially misinterpreted before referral as choroidal melanoma or metastasis. Visual acuity is poor in more than 60% of patients at 10 years, despite successful control of associated subretinal fluid in 76% patients.

Abstract
OBJECTIVES To analyze the results of intraocular surgery in patients treated for retinoblastoma and to assess the ocular and systemic outcomes. DESIGN Retrospective noncomparative case series. PATIENTS Forty-five consecutive patients who underwent an introcular surgery after treatment for retinoblastoma. MAIN OUTCOME MEASURES (1) Recurrence of retinoblastoma, (2) need for enucleation, and (3) systemic metastasis. Overall outcome was defined as favorable in the absence of any of these measures and unfavorable in the presence of 1 or more. RESULTS Thirty-four patients (76%) underwent a single procedure of cataract surgery, a scleral buckling procedure, or pars plana vitrectomy and 11 (24%) underwent a combination of 2 or more surgical procedures. In all, 16 patients (36%) achieved final visual acuity better than 20/200. Unfavorable outcomes included recurrence of retinoblastoma in 14 patients (31%), enucleation in 16 (36%), and systemic metastasis in 3 (7%). Five patients (20%) who underwent cataract surgery, 5 (63%) who underwent a scleral buckling procedure, and 9 (75%) who underwent pars plana vitrectomy manifested an unfavorable outcome. The median interval between completion of treatment for retinoblastoma and intraocular surgery was 26 months in patients with a favorable outcome vs 6 months in those with an unfavorable outcome. CONCLUSIONS Intraocular surgery after treatment for retinoblastoma may be justified in certain exceptional clinical situations. Cataract surgery is safe and effective in most cases. However, the need for a scleral buckling procedure and pars plana vitrectomy may be associated with a higher risk for recurrence of retinoblastoma, enucleation, and systemic metastasis, and a cautious approach is warranted.

Abstract
PURPOSE Ring melanoma of the anterior chamber angle is a rare variant of uveal melanoma that manifests as circumferential, flat tumor growth predominantly confined to the trabecular meshwork and other anterior chamber angle structures. We report the clinical and histopathological features, management, and prognosis of ring melanoma of anterior chamber angle. METHODS A retrospective review of clinical features, management, histopathologic features, and prognosis was performed. Of 8800 patients with uveal melanoma examined on the Oncology Service at Wills Eye Hospital over a 25-year period, only 14 patients (0.2%; 14 eyes) were classified clinically as ring melanoma of the anterior chamber angle. In no case was there appreciable involvement of the iris or ciliary body on clinical examination. RESULTS The patients were followed elsewhere for a mean of 8 months before intraocular malignancy was suspected. Upon referral to the Oncology Service, the intraocular pressure was greater than 22 mm Hg in the affected eye in all patients (mean, 36 mm Hg; median, 35 mm Hg; range, 24 to 48 mm Hg), and all patients were using at least two glaucoma medications. The melanoma infiltrated the anterior chamber angle for a mean of 10 clock hours (range, 8 to 12 clock hours). Tumor management consisted of enucleation in 13 cases and plaque radiotherapy in one case. Histopathologic examination revealed epithelioid cell type melanoma in one case, mixed cell type in nine, and spindle cell type in four. Of the 13 patients who underwent enucleation, tumor cells were found within the Schlemm canal in all cases. Five cases displayed invasion of the intrascleral canals, and three showed episcleral invasion. With the exception of two recent cases, 12 patients were followed for a mean of 64 months (median, 47 months; range, 23 to 225 months). Distant metastasis to the liver was detected in three of 12 patients (25%) after a mean follow-up of 78 months (median, 70; range, 37 to 128 months). CONCLUSIONS Ring melanoma of the trabecular meshwork and angle structures is a rare variant of diffuse uveal melanoma. It often masquerades as unilateral glaucoma and can be difficult to recognize clinically unless careful comparative gonioscopy is performed. Despite the relatively small tumor volume, life prognosis is guarded with distant metastasis in 25% at mean 6 years follow-up.

Abstract
PURPOSE To provide data on types of lesions that require orbital exenteration and discuss our experience with exenteration, emphasizing the eyelid-sparing technique. METHODS The records were reviewed on all patients who underwent orbital exenteration by the senior author and his colleagues. The underlying disease, method of exenteration, healing times, complications, cosmetic outcome, local tumor control, and patient survival were analyzed. RESULTS Of 56 orbital exenterations, 47 were done by eyelid-sparing technique and 9 by eyelid-sacrificing technique. The 9 tumors of eyelid origin that required exenteration included basal cell carcinoma (4), sebaceous gland carcinoma (3), squamous cell carcinoma (1), and melanoma (1). Four of the eyelid lesions were managed by the eyelid-sparing technique and 5 by the eyelid-sacrificing method. The 24 tumors of conjunctival origin included melanoma (20) and squamous cell carcinoma (4). The eyelid-sparing method was used in 22 of the 24 cases. The 10 primary orbital lesions included melanoma (3), malignant lacrimal gland tumor (3), a rhabdoid tumor, meningioma, Wegener's granulomatosis, and aspergillosis. The eyelid-sparing method was used in 8 of the 10 cases. Among intraocular tumors were uveal melanomas (10) and retinoblastoma (1). The eyelid sparing method was used in all 11. With the eyelid-sparing technique, the mean time from exenteration to wound healing and readiness for a prosthesis was 4 weeks (median, 2 weeks; range, 2 to 24 weeks). With the eyelid-sacrificing technique, the mean time was 68 weeks (median, 34 weeks; range, 2 to 340 weeks). Complications were few and cosmetic results were satisfactory. Local tumor control with exenteration was achieved in 53 of 56 cases, but metastasis occurred in 11 of 20 cases of conjunctival melanoma (55%) and in 6 of 10 patients with uveal melanoma (60%). Metastasis has developed in none of the 3 patients with malignant epithelial tumors of lacrimal gland origin. CONCLUSIONS Orbital exenteration is an appropriate procedure for orbital involvement by unresectable malignant tumors of the eyelids, conjunctiva, intraocular structures, and orbit. In most of these cases, including about half of tumors originating in the eyelids, an eyelid-sparing exenteration can be used to achieve more rapid healing.

Abstract
PURPOSE To report a pigmented conjunctival squamous cell carcinoma that clinically simulated a conjunctival melanoma. DESIGN Interventional case report. METHODS Ocular examination, surgical excision, and clinicopathologic correlation. RESULTS A 78-year-old white man developed a lightly pigmented mass at the temporal limbus of his right eye. The differential diagnosis included pigmented squamous cell carcinoma and malignant melanoma. Histopathologic examination revealed a malignant squamous cell tumor that contained foci of melanin pigment. The final diagnosis was pigmented conjunctival squamous cell carcinoma. CONCLUSION Conjunctival squamous cell carcinoma may rarely be pigmented and simulate a conjunctival melanoma.

Abstract
BACKGROUND Sclerochoroidal calcification is an unusual ocular condition that is believed to be idiopathic in most cases. OBJECTIVES To describe the clinical manifestations of sclerochoroidal calcification and to investigate its possible systemic associations. METHODS This noncomparative consecutive case series included patients diagnosed as having sclerochoroidal calcification based on clinical characteristics and diagnostic test findings. We analyzed the demographic, systemic, and ocular features of 27 such patients. Systemic evaluation included tests for calcium-phosphorus metabolism in 19 patients and renal tubular hypokalemic metabolic alkalosis syndromes (Bartter or Gitelman syndrome) in 13. RESULTS All the patients were asymptomatic older (mean age, 70 years) white individuals, incidentally noted as having a choroidal lesion on routine examination. Among 38 eyes, the main referral diagnoses were choroidal metastasis in 10 eyes (26%), choroidal melanoma in 8 (21%), and choroidal nevus in 4 (11%). Sixteen patients (59%) had unilateral clinical findings, while 11 (41%) had bilateral. The Snellen visual acuity was 20/50 or better in 37 eyes (97%). Cogan scleral plaque was visible anterior to the insertion of horizontal rectus muscles in 10 eyes (26%). Among 77 foci, there were a mean of 2 foci of sclerochoroidal calcification in each eye, 41 yellow (53%), 32 yellow-white (42%), 2 white (3%), and 2 orange (3%), measuring a mean 2.6 mm in diameter and 1.1 mm in thickness. The most common locations were postequatorial in 45 (58%), along the temporal vascular arcades in 30 (39%), and in the superotemporal quadrant in 43 (56%). A-scan and B-scan ultrasonography revealed dense echoes compatible with calcium, with orbital shadowing. All the lesions remained stable in size and configuration during a mean follow-up of 38 months. One patient developed a choroidal neovascular membrane over the area of sclerochoroidal calcification. Investigations for abnormal calcium-phosphorus metabolism in 19 patients revealed primary hyperparathyroidism in 1 patient (5%). Clinical and biochemical evaluation of 13 patients demonstrated hypomagnesemia in 6 (46%). Four patients (31%) met the criteria for the diagnosis of Gitelman syndrome. CONCLUSIONS Sclerochoroidal calcification usually manifests as multiple discrete yellow placoid lesions in the midperipheral fundus of asymptomatic older white individuals. Although most cases may be idiopathic in nature, some patients may have underlying systemic disorders involving abnormal calcium-phosphorus metabolism or renal tubular hypokalemic metabolic alkalosis syndromes. All patients with sclerochoroidal calcification should be tested for these treatable systemic associations.

Abstract
PURPOSE To describe the ophthalmic and systemic features in a series of patients initially seen with eyelid basal cell carcinoma associated with Gorlin-Goltz syndrome. DESIGN Retrospective noncomparative case series. PARTICIPANTS Of 105 consecutive patients with eyelid basal cell carcinoma managed at an Ocular Oncology Center between January 1973 and December 1999, four patients with Gorlin-Goltz syndrome were identified. METHODS The ophthalmic and systemic features, management, and outcome of patients with eyelid basal cell carcinoma associated with Gorlin-Goltz syndrome were analyzed. The published literature on Gorlin-Goltz syndrome, specifically related to genetics, systemic features, ophthalmic associations, and prophylactic management strategies, was reviewed. MAIN OUTCOME MEASURES Response of the eyelid basal cell carcinoma to treatment and the final systemic condition were the main outcome measures. RESULTS All four patients had a family history of Gorlin-Goltz syndrome. The systemic manifestations included multiple basal cell carcinomas in all the patients, frontal bossing or increased occipitofrontal circumference in three patients, palmar pits in two patients, odontogenic keratocyst in one patient, ectopic calcification in one patient, and bifid rib in one patient. The mean age at the detection of the first basal cell carcinoma was 30 years (range, 16-38 years). All four patients had multiple basal cell carcinomas on the face and elsewhere. The eyelid basal cell carcinoma was advanced with orbital infiltration in three patients, one of whom opted for palliative radiotherapy, whereas the other two underwent orbital exenteration. The fourth patient, who had localized recurrent basal cell carcinoma in the upper eyelid, was treated with excision and eyelid reconstruction. At the final follow-up (mean, 41 months), eyelid basal cell carcinoma was cured in three patients and stable in one patient. No patient had life-threatening sequelae of Gorlin-Goltz syndrome. CONCLUSIONS Gorlin-Goltz syndrome is a rare autosomal dominant cancer predisposition syndrome that may be associated with eyelid basal cell carcinoma. The associated systemic findings may be a clue to the diagnosis of this condition. It is important to recognize Gorlin-Goltz syndrome when a patient has multiple basal cell carcinomas or when a young patient with eyelid basal cell carcinoma is seen by an ophthalmologist, because lifelong monitoring is essential for patient management.

Abstract
Sebaceous gland carcinoma usually arises from meibomian or Zeis glands deep within the eyelid, but it can rarely arise within the conjunctival epithelium without a deep component. We describe a woman with a history of chronic blepharoconjunctivitis unresponsive to topical medications. Examination disclosed confluent papillary hypertrophy of the upper palpebral conjunctiva and deposits of white flaky material. Tarsoconjunctival punch biopsy revealed intraepithelial sebaceous gland carcinoma. Management consisted of frozen section-controlled complete tumor excision with removal of the entire posterior lamella of the right upper eyelid, cryotherapy to the margins, and reconstruction. Histopathologic analysis confirmed primary sebaceous gland carcinoma localized to the conjunctival epithelium without involvement of underlying meibomian or Zeis glands or the caruncle. Patients with unexplained chronic unilateral blepharoconjunctivitis or papillary hypertrophy of the palpebral conjunctiva should be considered for biopsy to rule out neoplasia, even when there is no sign of an underlying eyelid mass.

Abstract
PURPOSE To review the methods and results of management in a large series of patients with Coats disease, to determine risk factors for poor visual outcome and enucleation, and to propose a practical classification of Coats disease. METHODS In a retrospective consecutive series in 150 patients, Coats disease was defined as idiopathic retinal telangiectasia with intraretinal or subretinal exudation without appreciable signs of retinal or vitreal traction. We reviewed our experience with management, including observation, laser photocoagulation, cryotherapy, and various techniques of retinal detachment surgery and enucleation. The anatomic outcome, complications of treatment, visual results, and reasons for enucleation were tabulated. Factors predictive of poor visual outcome (20/200 or worse) and enucleation were determined using Cox proportional hazards regression models. Based on these observations, a staging classification of Coats disease, applicable to treatment selection and ocular prognosis, is proposed. RESULTS In 117 patients (124 eyes) with a mean follow up of 55 months (range, 6 months to 25 years) primary management was observation in 22 eyes (18%), cryotherapy in 52 (42%), laser photocoagulation in 16 (13%), various methods of retinal detachment surgery in 20 (17%), and enucleation in 14 (11%). Anatomic improvement or stability was achieved in 76% of eyes, and final visual acuity was 20/50 or better in 17 eyes (14%), 20/60 to 20/100 in eight (6%), 20/200 to finger counting in 30 (24%), and hand motion to no light perception in 49 (40%) Enucleation was ultimately necessary in 20 eyes (16%). Risk factors predictive of poor visual outcome (20/200 or worse) included postequatorial (P =.01), diffuse (P =.01), or superior (P =.04) location of the telangiectasias and exudation, failed resolution of subretinal fluid after treatment (P =.02), and presence of retinal macrocysts (P =.02). The main risk factors for enucleation were elevated intraocular pressure (greater than 22 mm Hg; P less than or equal to.001) and iris neovascularization (P less than or equal to.001). Coats disease was classified into stage 1, telangiectasia only; stage 2, telangiectasia and exudation (2A, extrafoveal exudation; 2B, foveal exudation) stage 3, exudative retinal detachment (3A, subtotal; 3B, total); stage 4, total detachment and secondary glaucoma; and stage 5, advanced end-stage disease. Poor visual outcome (20/200 or worse) was found in 0% of eyes with stage 1, 53% with stage 2, 74% with stage 3, and 100% of stages 4 and 5 Coats disease. Enucleation was ultimately necessary in 0% of stages 1 and 2, 7% of stage 3, 78% of stage 4, and 0% of stage 5 disease. CONCLUSIONS Carefully selected treatment can anatomically stabilize or improve the eye with Coats disease in 76% of eyes. However, poor visual outcome of 20/200 or worse commonly results. Patients who present with stages 1 to 3 Coats disease have the best visual prognosis, and patients with stages 4 and 5 have a poor visual prognosis.

Abstract
PURPOSE The purpose of this report is to review the clinical variations and natural course of Coats disease, using strict diagnostic guidelines. METHODS In a retrospective, consecutive series, Coats disease was defined as idiopathic retinal telangiectasia with intraretinal or subretinal exudation without appreciable signs of retinal or vitreal traction. We reviewed our experience with the clinical features, complications, and diagnostic approaches to Coats disease. RESULTS In 150 consecutive patients (158 eyes), Coats disease was diagnosed at a median age of 5 years (range, 1 month to 63 years), occurred in 114 males (76%), and was unilateral in 142 patients (95%). There was no predilection for race or laterality. The most common referral diagnoses were Coats disease in 64 cases (41%) and retinoblastoma in 43 (27%). The first symptom or sign was decreased visual acuity in 68 cases (34%), strabismus in 37 (23%), leukocoria in 31 (20%), and 13 patients (8%) were asymptomatic. Visual acuity at presentation was 20/200 to no light perception in 121 eyes (76%). The anterior segment was normal in 142 eyes (90%). The retinal telangiectasia involved the midperipheral or peripheral fundus in 156 of the 158 eyes (99%) and was restricted to the macular area in two eyes (1%); involved mainly the temporal fundus in 66 eyes (42%), inferior fundus in 41 eyes (26%), and more than one sector in 34 eyes (22%). Retinal exudation was present in all 12 clock hours in 86 eyes (55%) and six or more clock hours in 115 eyes (73%). There was a total retinal detachment in 74 eyes (47%) and neovascular glaucoma in 12 (8%). Retinal macrocysts were present in 18 eyes (11%), a vasoproliferative tumor in nine eyes (6%) and retinal neovascularization in four eyes (3%). Fluorescein angiography in 49 of the 158 eyes (37%) disclosed early hyperfluorescence of the telangiectasias and macular edema in 18 of eyes (37%). Ultrasonography typically showed a retinal detachment but no solid mass. CONCLUSIONS Coats disease is a distinct clinical entity characterized by idiopathic retinal telangiectasia and retinal exudation. It is usually unilateral, occurs mostly in young males, and can cause severe visual loss resulting from exudative retinal detachment. The clinician should follow strict criteria in making the diagnosis, to avoid confusing Coats disease with other forms of exudative retinopathy.

Abstract
PURPOSE To report an unusual case of solitary sequential bilateral breast metastases from choroidal melanoma. METHOD Case report. RESULTS A 48-year-old woman with a large choroidal melanoma in the left eye was treated with Iodine-125 brachytherapy and responded satisfactorily with decrease in tumor thickness. Thirty-seven months after treatment, she developed a solitary, circumscribed melanoma metastasis to the right breast, and 54 months after treatment, a similar metastasis was detected in her left breast. Both breast tumors were managed with lumpectomy. Systemic examination including magnetic resonance imaging of abdomen, chest, and head have been performed regularly and have been normal. At 61 months after treatment, the patient has no clinical evidence of metastatic disease elsewhere. CONCLUSIONS Uveal melanoma rarely metastasizes to breast tissue. A breast nodule in a patient with a history of uveal melanoma is most likely a primary breast tumor but may rarely represent a metastasis from uveal melanoma.

Abstract
OBJECTIVE To evaluate the outcome of contact transscleral diode laser cyclophotocoagulation (CTDC) in eyes with advanced glaucoma and to compare the efficacy in pediatric and adult patients. PATIENTS AND METHODS Included in the study were 41 eyes (39 patients) with advanced glaucoma (15 eyes of 13 pediatric patients and 26 eyes of 26 adult patients). The patients were followed at least for six months or until failure of the procedure, if shorter than 6 months. The mean follow-up of all patients was 10 months (median 8 months, range 3-24 months); the mean pretreatment intraocular pressure (IOP) was 34.5+/-10.9 mm Hg for all cases, 36.2+/-12.6 mm Hg in adult cases and 31.6+/-6.5 mm Hg in pediatric cases. RESULTS At last follow-up after first treatment, there was significant decrease in IOP and the mean reduction in IOP was 12.11+/-10.5 mm Hg for all eyes. The mean reduction in IOP adult (13.6+/-11.8 mm Hg) and (9.9+/-6.8 mm Hg) patients. While the success rate after the first diode laser therapy was 59%, it increased to 75% after retreatments. The most common complications were conjunctival hyperemia and anterior chamber reaction. There was no difference in the complication rate between the pediatric and adult cases. CONCLUSION CTDC is a safe and effective therapy in eyes with advanced refractory glaucoma in the short term. But multiple applications may be needed in the long term. The results in adult and pediatric patients were found to be similar in efficacy and safety.

Abstract
PURPOSE To report a case of an extramedullary plasmacytoma confined to the choroid. METHODS Interventional case report with cytopathologic correlation. RESULTS A 76-year-old asymptomatic woman presented with 2 globular orange and amelanotic choroidal lesions in the right eye. Fine needle aspiration biopsy of one of the choroidal lesions followed by immunocytochemical studies revealed monoclonal plasma cells, diagnostic of plasmacytoma. Systemic evaluation was negative, except for increased serum gamma globulin with immunoglobulin kappa spike on electrophoresis. The patient was managed by ocular external beam radiotherapy. At 9 years follow-up, she was free of local disease and never developed multiple myeloma. CONCLUSION Extramedullary plasmacytoma confined to the choroid is rare. It may present simulating other common amelanotic choroidal lesions. Fine needle aspiration biopsy and proper systemic evaluation are critical in establishing the diagnosis.

Abstract
PURPOSE To review the findings, management, and outcome in 33 cases of primary ophthalmic rhabdomyosarcoma. METHODS The records of 33 consecutive patients from a single ocular oncology center were analyzed retrospectively for outcomes of final visual acuity, local recurrence, and distant metastasis. RESULTS Rhabdomyosarcoma was primarily located in the orbit m 25 cases (76%), conjunctiva in 4 (12%), eyelid in 1 (3%), and uveal tract in 3 (9%). Findings had been present for a mean of 5 weeks and included proptosis in 10 patients (30%), eyelid swelling in 7 (21%), and blepharoptosis in 6 (18%). The initial diagnoses before referral to us included primarily rhabdomyosarcoma in 8 cases (24%), conjunctivitis in 5 (15%), cellulitis in 5 (15%), and pseudotumor in 4 (12%). Tumors were classified according to the Intergroup Rhabdomyosarcoma Study Group staging and treatment protocols as group I in 4 cases (12%), group II in 12 (36%), group III in 16 (48%), and group IV in 1 case (3%). Treatment included surgical debulking, chemotherapy, and radiotherapy. Local tumor recurrence was detected in 6 patients (18%), lymph node spread in 2 (6%), and distant metastasis in 2 (6%). Long-term visual outcome of the 28 patients who maintained their globe was 20/20 to 20/40 in 11 patients (39%), 20/50 to 20/100 in 5 (18%), and 20/200 or worse in 12 (43%). Mean follow-up was 8.3 years; tumor-related death occurred in 1 patients (3%). CONCLUSIONS Rhabdomyosarcoma can present in the orbit, eyelid, conjunctiva, and uveal tract. Following treatment, local tumor recurrence occurs in 18% of cases, metastasis in 6%, and death in 3%.

Abstract
OBJECTIVE To analyze patient management and prognosis after vitrectomy in eyes with unsuspected retinoblastoma. DESIGN Retrospective, noncomparative case series. PARTICIPANTS Eleven consecutive patients who had undergone vitrectomy on an eye with unsuspected retinoblastoma. MAIN OUTCOME MEASURES The two main outcome measures were ultimate patient management and the development of retinoblastoma metastasis. RESULTS Of more than 900 consecutive patients with retinoblastoma managed on the Ocular Oncology Service at Wills Eye Hospital in Philadelphia, 11 (1%) had prior vitrectomy in an eye with viable tumor before referral to us for suspected retinoblastoma. The main preoperative diagnoses included vitreous hemorrhage in seven patients (64%), toxocariasis in two patients (18%), toxoplasmosis in one patient (9%), and endophthalmitis in one patient (9%). In no case was retinoblastoma suspected before vitrectomy. The mean patient age at vitrectomy was 6 years. Retinoblastoma was later suspected during vitrectomy in two patients (18%), on cytologic examination of the vitrectomy specimen in eight patients (73%), and after referral in one patient (9%). The mean interval between vitrectomy and referral to us was 23 days. On examination, the globe was classified as Reese-Ellsworth group Vb in all 11 patients (100%). Anterior chamber tumor cells were clinically visible in four eyes (36%), hyphema in two eyes (18%), and iris neovascularization in two eyes (18%). Retinoblastoma cells were visualized in the vitreous in seven eyes (64%) and not visualized in four eyes (36%) that had vitreous blood. Enucleation was necessary in all 11 patients (100%). Adjuvant treatment was delivered in 10 patients (91%), using orbital radiotherapy in nine patients (82%) and chemotherapy in nine patients (82%). Histopathologic evidence of retinoblastoma invasion was documented in the episclera (two eyes; 18%), anterior chamber (seven eyes; 64%), iris (five eyes; 45%), ciliary body (five eyes; 45%), choroid (three eyes; 27%), and optic nerve (four eyes; 36%; prelaminar, two eyes; postlaminar, two eyes). The vitrectomy ports, Tenon's fascia, cut end of the optic nerve, and orbit were free of tumor. Of the 10 patients who received prophylactic chemotherapy, radiotherapy, or both in addition to enucleation for prevention of retinoblastoma metastasis, none (0%) experienced metastasis or orbital recurrence during the mean follow-up of 7 years (range, 0.2-24 years) from the time of retinoblastoma diagnosis. However, one patient was referred to us after the development of metastatic retinoblastoma, and despite aggressive chemotherapy and radiotherapy after enucleation, died 24 months later. CONCLUSIONS Retinoblastoma may present with atypical features such as vitreous hemorrhage or signs of vitreous inflammation, particularly in older children. Vitrectomy should be avoided in these cases until the possibility of underlying retinoblastoma is excluded. If vitrectomy is performed in an eye with unsuspected retinoblastoma, enucleation combined with adjuvant chemotherapy, radiotherapy, or both without delay is advised to prevent systemic tumor dissemination.

Abstract
Cellular blue nevus is an uncommon pigmented tumor in the conjunctiva, where it generally appears as a deep, circumscribed, pigmented conjunctival mass. We report a case of conjunctival blue nevus that clinically resembled primary acquired melanosis and gave rise to conjunctival melanoma. A 41-year-old man developed a diffuse pigmented mass in the inferior fornix of his left eye. Over a 20-year period, he noted slight progression of the pigment. Foci of epibulbar pigmentation were also present. The lesion resembled primary acquired melanosis. Excisional biopsy and adjuvant cryotherapy were performed. Histopathologic examination disclosed an intense infiltrate of heavily pigmented dendritic melanocytes with aggregates of less pigmented plump cells in the substantia propria. The conjunctival epithelium was normal. Malignant cellular features consistent with melanoma were observed in some foci. Cellular blue nevus of the conjunctiva can simulate primary acquired melanosis and can give rise to malignant melanoma. Arch Ophthalmol. 2000;118:1581-1584

Abstract
PURPOSE To report the concurrent occurrence of choroidal melanoma in a son and father. METHODS Case reports. The likelihood of familial occurrence of uveal melanoma in which father and son are affected was estimated using the principles of probability. RESULTS Unilateral choroidal melanoma was diagnosed in a 41-year-old man. Three months later, his 68-year-old father presented with a pigmented choroidal mass that greatly increased in size during the next 6 months and was diagnosed a choroidal melanoma. No personal or family history of atypical moles, cutaneous melanoma, or other malignancy existed. The likelihood of familial occurrence of uveal melanoma using principles of probability was estimated to be 1 in 10 million. CONCLUSION Considering the low prevalence of uveal melanoma in the general population, the likelihood of uveal melanoma occurring in a family setting is remote.

Abstract
UNLABELLED The purpose of this study is to evaluate the ocular findings in patients with the primary antiphospholipid syndrome (APS). PATIENTS AND METHODS Twenty-two patients (44 eyes) with primary APS (17 women, 5 men) were examined. All patients were younger than 50 years (median age; 37.5 years). In 18 patients, fundus flourescein angiography was performed in addition to the ophthalmologic examination. RESULTS Sixteen patients (72.7%) described visual symptoms. Anterior segment was normal in 19 patients (86.4%). Posterior segment abnormalities were observed in 15 patients (68.2%). Venous dilatation and tortuosity were the most common ocular findings. Retinal vascular occlusive disease was detected in 5 patients (22.7%). Flourescein angiography abnormalities were noted in 14 of the 18 patients (77.8%). The most common angiographic finding was pigment epithelial window defects. CONCLUSIONS Our results indicate that posterior eye segment involvement is relatively common in the primary APS. It also seems that the screening for APS is important in young patients with retinal vascular occlusion, especially in those without conventional risk factors.

Abstract
A 41-year-old asymptomatic woman was referred for enucleation of a 7. 5-mm-thick intraocular tumor suspected to be choroidal melanoma. The clinical findings combined with imaging studies suggested instead a diagnosis of giant nodular posterior scleritis. A scleral biopsy was performed to confirm the diagnosis. After 12 years of observation, the lesion has remained stable and visual acuity has been preserved. Nodular posterior scleritis can present with no symptoms of pain, redness, or visual disturbance and can remain quiet for many years. It must be clinically differentiated from choroidal melanoma.

Abstract
OBJECTIVES To clinically evaluate topical mitomycin chemotherapy in patients with diffuse, multifocal, or recurrent primary acquired melanosis with atypia and/or conjunctival malignant melanoma and to histopathologically study ocular tissue samples obtained before and after treatment. METHODS Chemotherapy with topical mitomycin, 0.04% 4 times daily, was administered for 28 days as the primary and only treatment in 7 patients (after biopsy) and for 7 days as adjuvant therapy to excision and cryotherapy in 5 patients. Mean follow-up was 38 months. Five patients developed subconjunctival recurrences, for which 2 underwent orbital exenteration and 3 were treated conservatively. Histopathologic specimens of conjunctival, adnexal, and ocular tissues obtained before and after chemotherapy were evaluated. RESULTS Regression of tumor was observed in 11 patients with primary or adjuvant topical mitomycin chemotherapy. One patient with nodular melanoma was resistant to mitomycin chemotherapy. Histopathologic findings included regionally variable conjunctival epithelial atrophy and thinning. Dyskeratosis and focal keratinization in conjunctival epithelium were noted. Epithelial nuclei were occasionally pyknotic in areas of atrophic epithelium. Subepithelial inflammation was present and was most intense in areas with severe atrophy and/or keratosis. Two patients with primary treatment and 2 with adjuvant treatment developed subconjunctival recurrence. In patients with recurrent malignant melanoma, the deeper layers of the lamina propria were involved, with sparing of the epithelium and superficial lamina propria. Transient keratoconjunctivitis was observed in all patients during treatment. In evaluation of the exenteration specimens, corneal, scleral, episcleral, retinal, and anterior structures were within normal limits. CONCLUSIONS Topical mitomycin chemotherapy was found to induce regression of conjunctival melanoma and primary acquired melanosis with atypia. When mitomycin chemotherapy was used as an adjuvant to excision and cryotherapy, 2 (40%) of 5 patients experienced tumor recurrence at a mean of 4.3 years' follow-up. Our histopathologic findings demonstrated a long-term mitomycin chemotherapy-related effect on the conjunctiva. The degree of chronic atrophy and inflammation was not clinically significant. The pattern of effect and location of recurrent disease suggest that this regimen of topical mitomycin chemotherapy was most effective for superficial tumors. No complications that would preclude use of our dose regimen were noted. Although subconjunctival or orbital recurrences were noted, topical mitomycin chemotherapy warrants further investigation as an alternative treatment for primary acquired melanosis with atypia and conjunctival malignant melanoma.

Abstract
Retinoblastoma is the most common primary intraocular tumour in children, with an incidence of 1 in 15,000 live births. Treatment strategies for retinoblastoma have gradually evolved over the past few decades. There has been a trend away from enucleation (removal of the eye) and external beam radiation therapy toward focal 'conservative' treatments. Every effort has been made to save the child's life with preservation of eye and sight, if possible. Primary enucleation continues to be the commonly used method of treatment for retinoblastoma. It is employed in situations where eyes contain large tumours, long standing retinal detachments, neovascular glaucoma and suspicion of optic nerve invasion or extrascleral extension. Most of these eyes either have or are expected to have no useful vision. Radiation therapy continues to be an effective treatment option for retinoblastoma. However, external beam radiotherapy has unfortunately been associated with secondary non-ocular cancers in the field of radiation (primarily in children carrying the RB-1 germline mutation). Ophthalmic plaque brachytherapy has a more focal and shielded radiation field, and may carry less risk. Unfortunately, its applicability is limited to small to medium-sized retinoblastomas in accessible locations. Cryotherapy and transpupillary thermotherapy (TTT) have been used to provide control of selected small tumours. TTT is an advanced laser system adapted to the indirect ophthalmoscope which provides flexible nonsurgical treatment for small retinoblastomas. Recent research in the treatment of retinoblastoma has concentrated on methods of combining chemotherapy with other local treatment modalities (TTT, radiotherapy, cryotherapy). This approach combines the principle of chemotherapeutic debulking in paediatric oncology with conservative focal therapies in ophthalmology. Termed chemoreduction, intravenous or subconjunctival chemotherapy is used to debulk the initial tumour volume and allow for local treatment with TTT, cryotherapy and plaque radiotherapy. Cyclosporin has been added to the chemotherapy regimen in several centres. Other clinical settings where chemotherapy is considered are situations where the histopathology suggests a high risk for metastatic disease and where there is extraocular extension. There is no consensus that chemotherapy is needed when choroidal invasion is observed on histopathology. However, in patients where the retinoblastoma is noted beyond the cut end of the optic nerve or if there is disruption of the sclera with microscopic invasion of the orbital tissue, treatment has been helpful. Systemic and intrathecal chemotherapy with local and cranial radiotherapy has improved the survival of these patients. Most recently, the use of new chemotherapy modalities with haematopoietic stem cell rescue or local radiotherapy has increased the survival of patients with distant metastasis. Nevertheless, the prognosis of patients with central nervous system involvement is still poor.
