Coats' Type Retinitis Pigmentosa and Subretinal Neovascularisation in a Patient With Renal Failure

Bilateral Neovascular Glaucoma With Retinitis Pigmentosa: A Clinical Challenge

“…Most of these had some evidence of posterior segment ischemia which was absent in our case that led to the clinical dilemma. The reported mechanisms of NVG in these studies include loss of receptor cells, intraocular inflammation secondary to photoreceptor destruction, co-existent vaso-occlusive diseases, or altered metabolic environment of the retinal vasculature, retinal pigment epithelium (RPE) dysfunction, and capillary non-perfusion [5][6][7][8]. Chronically raised IOP by undiagnosed glaucoma was the trigger causing ocular ischemia rather than RP/retinal pathology that explained the failure of any response with retinal PRP in this case.…”

“…Differentials for bilateral NVG which were considered in this case included systemic inflammatory diseases/atherosclerotic diseases, carotid occlusive diseases leading to OIS, and PDR masked by RP, all of which were ruled out in our case [3,[6][7][8]. Other causes for isolated rubeosis iridis include ocular tumors, chronic retinal detachment or endophthalmitis, chronic inflammation or uveitis, and ocular trauma [8].…”

Coats‐like retinopathy in a Young Indian Rhesus Macaque (Macaca mulatta)

“…This animal, also, had no history of laser therapy. Rare cases of bilateral Coats retinopathy have been reported in a 2-year girl with severe bone marrow hypoplasia [10] and Reiter's disease [2]. However, complete blood counts, histology, and laboratory tests suggested that the current cases were not consistent with RB, RP, juvenile diabetes, bone marrow hypoplasia, and Reiter's disease.…”

“…Rare patients with advanced RP can have exudative vasculopathy, often called Coats‐like disease. Retinal exudation is associated with many other pediatric conditions including juvenile diabetes and laser therapy . Diabetic retinopathy is an ocular manifestation affecting up to 80% of patients with juvenile diabetes.…”
