Cyclodiode treatment of neovascular glaucoma secondary to Coats' disease

Severe Corneal Melt Post Trans-Scleral Cyclodiode in a Case of Neovascular Glaucoma Secondary to Coats Disease: A Case Report

A novel case of neurotrophic keratitis and severe corneal melt requiring surgical management is presented 1 month following trans-scleral cyclodiode for Coats disease and neovascular glaucoma. Risk factors contributing to the complication include previous extracapsular cataract surgery, perioperative use of topical non-steroidal anti-inflammatories and dexamethasone/neomycin, as well as other topical drops containing preservatives such as benzalkonium chloride. Meticulous consideration of preoptimization of the ocular surface and rationalization of perioperative eye drop regimes is discussed.

Neovascular Glaucoma in Children: A case series and a review of the literature

PURPOSE

To study the uncommon causes and treatment options for neovascular glaucoma in children.

PATIENTS AND METHODS

A review of the literature on neovascular glaucoma in children was conducted and we present three cases of neovascular glaucoma in children.

RESULTS

We present three cases of neovascular glaucoma: two cases were secondary to a retinal vasoproliferative tumor-one to neurofibromatosis type 1 and the other to exudative retinopathy secondary to mild retinopathy of prematurity-and one case was secondary to a central retina vein occlusion secondary to an optic nerve glioma. Vision in the affected eye was severely impaired in all the children.

CONCLUSION

The diagnosis and treatment of neovascular glaucoma in children is challenging and often a complication of a systemic or late-stage ocular condition. An appropriate diagnosis and estimation of the visual potential are essential to determine the correct treatment, especially in young children.

Acute Angle-closure Glaucoma as a First Presentation of Coats' Disease: A Case Report

PURPOSE

The purpose of this study was to report an unusual first manifestation of Coats' disease presenting as an acute angle-closure glaucoma attack in an adult patient.

PATIENTS AND METHODS

A 37-year-old African woman presented to the emergency department with severe headache, ocular pain, and no light perception in the left eye. The left pupil was middilated and nonreactive, and the intraocular pressure (IOP) by applanation tonometry was 47 mm Hg. Slit-lamp examination revealed anterior subcapsular opacification (glaukomflecken), posterior synechiae, and total angle closure with iris bombé. A fundus examination revealed macular exudation, inferior vascular dilation, and tortuosity with peripheral telangiectasia and macroaneurysms, in addition to partial exudative retinal detachment involving the macula. On the basis of these findings, Coats' disease was diagnosed.

RESULTS

The patient was treated with antiglaucoma medications and laser peripheral iridotomy to control the IOP, which had decreased to 21 mm Hg the following day. Diode laser transscleral cyclophotocoagulation was performed to further decrease the IOP. After completing a 360 degree laser, the IOP decreased to 8 mm Hg and then stabilized around 12 mm Hg. The vision remained no light perception; however, the patient felt major symptomatic relief.

CONCLUSIONS

The present case describes acute angle-closure glaucoma as an initial presentation of Coats' disease in adults. Clinicians should be aware that this unique presentation in Coats' disease can occur even without retinal detachment.
