Etiology determines intraocular pressure treatment

Dr. Patients usually have symptomatic vision loss secondary to cataract formation and tend not to have significant inflammation on examination. Uveitis is inflammation of the uvea. Complications are more frequently related to hyphema than microhyphema. Cataract surgery was performed, and a posterior chamber IOL was inserted. Cunningham described two issues—failure to distinguish leukocytes from pigment and failure to recognize acute angle closure. Pathergy (exaggerated skin injury occurring after minor trauma), read by a physician at 24-48 hours.

When indicated, pathogen-specific antimicrobial agents should also be given. Treatments of uveitis depend upon the cause, which may be infectious or non-infectious. 9 – Rao PV, Deng P, Maddala R, Epstein DL, Li CY, Shimokawa H. Hyphema can be caused by either blunt or penetrating injury, but when it is a result of penetrating trauma, its management and role in glaucoma are dictated by the overall globe injury. The prevalence and severity of diseases in economically deprived population differ from those in rest of the world [2] because of lack of good primary health care, poor affordability and poor compliance. The incidence of cataract in uveitis varies from 57% in pars planitis [2] to 78% in Fuchs heterochromic iridocyclitis (FHI) [3]. Its role in the etiopathogenesis of pars planitis is unknown.[36] HLA associations include HLA-DR, B8, and B51, the most significant being HLA-DR which occurs in 67-72% of patients.

It is characterized by progressive acquired loss of retinal ganglion cells leading to optic nerve atrophy and visual field deficits. The presentation of corticosteroid-induced IOP elevation in the uveitic patient differs from the preceding mechanisms because there is a delay between initiation of the medication and the increase in IOP. Uveitis was diagnosed based on clinical examination. Another concern is related to the possible induction of chronic conjunctival inflammation that may have a negative effect in future filtering surgeries. Trabeculectomy can be performed with or without the use of antimetabolites to treat uveitic glaucoma. A quiet eye with a pigmented central keratic precipitate with a clear halo and no AC reaction (Figure  B) was recorded before starting the drops. “Be careful not to undertreat the uveitis because persistent active inflammation can result in other ocular complications, including loss of vision.

The clinical presentation, including stellate KPs, diffuse iris atrophy, lack of posterior synechiae and evidence of mild vitritis are all in favor of FHI.There are few uveitic entities that resemble FHI. Inflammation in patients with the ICE syndrome was mentioned in few early reports and more than one author described the onset of uveitis in these patients [10, 12]. The visual acuity was 20/200 in the right eye and 20/25 in the left eye. Cunningham noted that so-called “soft steroids,” including loteprednol etabonate (Lotemax/Alrex, Bausch + Lomb), rimexolone (Vexol, Alcon), and low-concentration formulations of prednisolone acetate, should not be used as a strategy for mitigating corticosteroid-induced IOP elevation until the inflammation is controlled. In the mixed mechanism cause, IOP is elevated as a result of chronic inflammation-induced permanent damage to the outflow system and/or formation of peripheral anterior synechiae, causing angle closure. Topical acyclovir ointment was administered to patients with active dendritic keratitis and topical corticosteroids were initiated after epithelial keratitis healed. Treatment for the IOP is based on the medical and surgical approaches generally used to manage glaucoma.

Orthoptic examination, fluorescein angiography and visual fields examination were performed in selected cases. The treatment includes corticosteroids to control inflammation, and antiglaucoma medications notably beta-blockers and carbonic anhydrase inhibitors to control IOP. A topical carbonic anhydrase inhibitor is used as a second-line agent, but if a more potent IOP-lowering effect is needed, an oral carbonic anhydrase inhibitor is considered. She had no history of uveitis. Pseudoexfoliation often occurs alongside glaucoma, accounting for up to 20 percent of open-angle glaucoma cases.1 Of the patients with pseudoexfoliation, a fifth will present with glaucoma and elevated pressure, but 15 percent more will develop glaucoma within 10 years.1 Dr. Cunningham said he prescribes a prostaglandin analogue, which has the benefit of once-daily instillation. Postoperative complications included severe hyphema in the AC, bleb leakage, choroidal detachment, cataract progression requiring surgery, hypotonic maculopathy, and blebitis/endophthalmitis.

Typically, the insulin-dependent diabetic is easier to manage because patients can increase their insulin to compensate for corticosteroid-induced hyperglycemia. The patients symptoms disappeared three days later, and she chose to try Alphagan P (brimonidine, Allergan) bid O.D. The situation in rural parts of Liberia, Sierra Leone and Guinea is less clear. During the procedure, we carefully dissected fibrotic subconjunctival tissue from the area of the previous revision. Evaluation and management of elevated IOP in patients with uveitis. Ophthalmology, June 2010; Focal Points, Volume XXVIII, Number 6, Module 3 of 3.
