Purpose: Congenital ectropion uvea is a rare anomaly, which is associated with open, but dysplastic iridocorneal angles that cause childhood glaucoma. Herein, we present 3 cases of angle-closure glaucoma in children with congenital ectropion uvea. Observations: Three children were initially diagnosed with unilateral glaucoma secondary to congenital ectropion uvea at 7, 8 and 13 years of age. The three cases showed 360° of ectropion uvea and iris stromal atrophy in the affected eye...

REVIEW
David M Clive, Vijay K Vanguri
The syndrome of tubulointerstitial nephritis and uveitis (TINU) is a multisystemic autoimmune disorder that may occur in response to various environmental triggers, including drugs and microbial pathogens. Evidence exists of HLA antigen-related genetic predisposition to developing TINU. The resulting inflammation affects chiefly the ocular uvea and renal tubules, although other organs may be involved. TINU is uncommon; only about 200 cases are on record since its original description 40 years ago, although it is possible that new ones are no longer being reported...

Spontaneously occurring ocular neoplasia is rarely reported in rabbits. This case series presents four cases of rabbits diagnosed with iridociliary tumors, which have not been previously reported in this species. Major pathological findings include epithelial tumors affecting the anterior uvea with variable pigmentation and basement membrane formation. Follow-up information was only available for two cases, but neither showed evidence of metastasis, suggesting that the prognosis for these tumors in rabbits, as in other species, may be very good...

BACKGROUND: Uveitis is the inflammation of the uvea that often occurs in children. There are many causes of disease, but some of them do not have any reasons and are then called idiopathic uveitis. Cytokines play an important role in the regulation of the immune response. Determination of cytokine profiles could contribute to the explanation of the etiology of uveitis and could serve to evaluate the inflammation intensity as well as be helpful in the early diagnosis this disease. The purpose of this study was to determine the serum level of selected inflammatory cytokines, such as interleukin-6 (IL-6), interleukin-8 (IL-8), and tumor necrosis factor α (TNF-α) and to compare their diagnostic power as a markers of idiopathic anterior uveitis in children...

Malignant melanoma of the uvea is the most common primary malignant tumor in the eye. We aimed to analyze GNAQ and GNA11 mutations in uveal melanomas using formalin-fixed, paraffin-embedded material and correlate the results with clinicopathological parameters. Tumor tissue was microdissected followed by amplification of GNAQ exon 4 and 5, GNA11 exon 4 and 5, and finally analyzed by Sanger sequencing. A total of 64.4 GNA11/GNAQ mutations, including ten yet unreported, were found. Two cases showed multiple mutations...

The most common iris lesions are iris nevi, iris melanomas and iris pigment epithelium cysts. However, there is an abundance of rare differential diagnoses that have to be considered, including other melanocytic and non-melanocytic lesions. Diagnostic tools include the slit lamp examination, gonioscopy, tonometry, transillumination, ultrasound biomicroscopy (UBM), optical coherence tomography, fluorescein angiography and standardized photography-assisted documentation. The timely identification of malignant lesions (i...

We report a case of sympathetic ophthalmia 1 month following trauma in a 71-year-old immunocompetent female patient of Indian origin. The patient was hospitalized with signs and symptoms of meningism, ataxia, and neurosensory deafness. We explore and provide further clinical evidence in supporting the hypothesis of antigen cross-reactivity derived from tissues with common neural crest embryological background such as the uvea and cells of the labyrinth. The patient was human leukocyte antigen-A2 positive and treatment with oral steroids and cyclosporine has managed to have favorable results and control the inflammation...

Uveal metastasis is the most common intraocular malignancy. Lung cancer is one of the most common malignancies that metastasize to uvea. Iris involvement is rarely reported. Here we report a case of iris metastasis from pulmonary adenocarcinoma that was treated with photodynamic therapy (PDT). A 65-year-old Chinese man was referred to our hospital for iris white neoplasm and blurred vision for 2 weeks in his right eye. His accepted pulmonary lobectomy, radiotherapy and chemotherapy for pulmonary adenocarcinoma 1year ago and liver metastases were found 2 months earlier...

Melanoma is the most common type of primary cancer to affect the adult eye. Approximately 95% of ocular melanomas are intraocular and arise from the uvea (i. e. iris, ciliary body, and choroid), while the remaining 5% are located in the conjunctiva. Although both uveal and conjunctival melanomas are thought to derive from malignantly transformed melanocytes, uveal melanoma is clinically and biologically distinct from conjunctival melanoma, and indeed from its more common cutaneous counterpart. Intense efforts have been recently made to understand the molecular biology involved in the development of ocular melanomas, and in their progression...
