Half-half PDT is a feasible treatment for chronic CSC. However, there was a lower success rate at 6 months compared with the control group.

Background Mucopolysaccharidoses ( MPS s) are a group of rare lysosomal storage disorders characterized by the accumulation of glycosaminoglycans in various tissues and organs. Ocular problems that affect the cornea, trabecular meshwork, sclera, retina, and optic nerve are very common in these patients. However, there was limited literature focusing on comprehensive ocular findings in different types of MPS . Methods We retrospectively reviewed the clinical ophthalmologic features and electrodiagnostic results of 50 Taiwanese patients with a diagnosis of MPS (34 males and 16 females; age range, 1.1–34.9 years; nine with MPS I, 17 with MPS II , 17 with MPS IV , and seven with MPS VI ). Results Among 44 patients with available data for visual acuity, 15 patients (34%) had a visual acuity of less than 0.5 (6/12) equivalent in their better eye, including 71% of those with MPS VI , 38% with MPS IV , 29% with MPS I, and 14% with MPS II . Severe corneal opacities existed in 57% of MPS VI patients and 11% of MPS I patients, compared with none for MPS II and MPS IV patients. Among 80 eyes with available data of refraction, 11 eyes (14%) had myopia (≦−0.50 D), 55 eyes (69%) had hyperopia (≧0.50 D), and 55 eyes (69%) had high astigmatism (≧1.50 D). Ocular hypertension was found in 45% (28/62) of eyes. There were 16% (14/90), 11% (10/90), 13% (12/90), 31% (27/86), and 79% (30/38) of MPS eyes with lens opacities, optic disc swelling, optic disc cupped, retinopathy, and visual pathway dysfunction, respectively. Intraocular pressure was positively correlated with the severity of corneal opacity ( p < 0.01). Conclusions Ocular complications with significant reduction in visual acuity are common in MPS patients. Diagnostic problems may arise in these patients with severe corneal opacification, especially for those with MPS VI and MPS I.

We presented a rare case of a sole choroidal metastatic tumor from esophageal squamous cell carcinoma (ESCC) without other organ metastasis in Taiwan. A 43-year-old male with ESCC was referred for a 1-month history of decreased vision in his left eye. A 5.7 mm thick, yellow choroidal tumor occupied posterior pole, featured with pinpoint hyperfluorescence on angiography and subretinal fluid on optical coherence tomography. Positron emission tomography showed a singular hypermetabolic focus in the left eye. The tumor regressed with complete response and the vision preserved after radiation with total 57.60 gray applied by tomotherapy. The gastrointestinal system is the third most common metastatic origin in Taiwan while esophageal cancer metastasizing to choroid is rare. The discrepancy between the high prevalence of primary ESCC and the rareness of choroidal metastasis from ESCC is undetermined.
