Thirty-two eyes (94.1%) had a history of a glaucoma diagnosis, which had been treated for 10.0 ± 10.1 years. Glaucoma in the fellow eye was noted in 16 cases (47.1%) and a history of Posner-Schlossman syndrome was noted in 13 cases (38.2%). Visual fields measured using a Humphrey field analyzer were normal-to-early stage (MD>-6dB) in 16 eyes (47.1%) and middle-to-late stage (MDâ¤-6dB) in 18 eyes (52.9%). The intraocular pressure decreased from 22.4 ± 10.6 mmHg at the initial visit to 14.9 ± 7.9 mmHg after medical treatment, including 0.5% topical ganciclovir (GCV) with and without a systemic anti-CMV agent, corticosteroid eye drops, and an anti-glaucoma agent (p< 0.01). During the follow-up period of 4.8 ± 3.0 years (range, 0.2â 10 years), 16 eyes (47.1%) required glaucoma surgery, including filtering surgery (7 eyes) and trabeculotomy only (9 eyes).Conclusion: Our case series showed that most of the patients with CMV corneal endotheliitis had glaucoma. Although medical therapy, including 0.5% topical GCV, had efficacy in lowering the intraocular pressure, one-half of the cases required glaucoma surgery. Therefore, ophthalmologists should strive to make an earlier diagnosis of CMV corneal endotheliitis by utilizing PCR testing of aqueous humor samples to prevent sight-threatening glaucomatous damage.Keywords: cytomegalovirus, corneal endotheliitis, secondary glaucoma, antiviral treatment |
