To report two cases with corneal sterile infiltration presumably due to topical ocular hypotensive agent.. Case report.. Case 1: A 65-year-old man presented with corneal opacity and neovascularization in his left eye. A diagnosis of glaucoma was made 2 years previously, and anti-glaucoma agents were prescribed (brimonidine tartrate, ripasudil hydrochloride hydrate, and brinzolamide) for both eyes. Case 2: A 75-year-old woman noticed corneal opacity in the left eye. A diagnosis of glaucoma was made 35 years previously, and anti-glaucoma agents were prescribed (brimonidine tartrate, 1% dorzolamide, and bimatoprost) for both eyes. In both cases, ocular examination revealed follicular conjunctivitis and blepharitis in both eyes, and corneal sterile infiltration with neovascularization in the left eyes. The three topical drugs were discontinued and replaced with 0.1% fluorometholone. Both the blepharitis and corneal sterile infiltration improved thereafter, although corneal opacity remained across the stromal layer.. We encountered two cases of corneal and conjunctival complications that were suspected as side effects after brimonidine eye drop use. Special care should be taken to observe the condition of ocular surface when topical brimonidine is administered.

Subclinical inflammation may be observed in patients using topical antiglaucomatous drugs. The objective of this study was to investigate inflammation in conjunctiva of glaucoma patients using prostaglandin analogs, by the detection of an immunogenetic marker (HLA-DR) and compare the effect of 3 different drugs: latanoprost, bimatoprost, and travoprost in the induction of this inflammation.. Thirty-three patients with primary open-angle glaucoma were evaluated without and with prostaglandin analogs topical therapy. Imprints of conjunctival cells were obtained, fixed on glass slides, and prepared for immunohistochemical analysis.. Before the use of prostaglandin analogs, 4 of the 33 patients evaluated presented expression of HLA-DR in the conjunctiva (mild). After 1 month on prostaglandin analog treatment, all but 1 patient presented HLA-DR staining. HLA-DR expression of these 32 patients was scored as mild (19 patients), medium (11 patients), or intense (2 patients). The differences were statistically significant both when the presence and the increased expression of HLA-DR were considered (P<0.001). When the 3 different groups were analyzed (latanoprost, bimatoprost, and travoprost) no statistically significant difference was found (P=0.27).. The use of prostaglandin analogs eye drops provokes a subclinical inflammatory reaction, observed by HLA-DR expression, even after a short period of treatment, independently of the class of the prostaglandin analogs used.

To evaluate histopathologic signs of conjunctival inflammation in patients with conjunctival hyperemia induced by bimatoprost treatment.. Prospective interventional study.. The study included 15 eyes of 15 patients scheduled for cataract surgery. Patients in the treatment group (n = 9) exhibited trace to moderate conjunctival hyperemia when treated with bimatoprost 0.03% every day for 15 to 30 days before surgery. The control group (n = 6) included untreated patients with no ocular disease other than cataract. Conjunctival biopsies were obtained for histologic evaluation with light microscopy.. Vascular congestion was observed in biopsies from 7 patients (78%) in the bimatoprost group and 5 patients (83%) in the control group. Signs of inflammation were found in biopsies from 2 patients (22%) in the bimatoprost group and 2 patients (33%) in the control group.. Histopathologic signs of inflammation were no more frequent in conjunctival specimens from bimatoprost-treated patients with trace to moderate hyperemia than in those from untreated control subjects.
