Chronic open-angle glaucoma should always be excluded (see Chapter 11). The major complications associated with retinal vein occlusion are reduced vision from macular edema, neovascular glaucoma secondary to iris neovascularization, and retinal neovascularization. 1. MACULAR EDEMA IN RETINAL VEIN OCCLUSION Macular dysfunction occurs in almost all

patients with advanced glaucoma. The main side effects are a rise in pressure for 1–4 hours in about one-third of eyes, usually preventable by pretreatment with apraclonidine drops, and a rise in pressure for 1–3 weeks in about 2% of treated eyes. Initial treatment with 50 laser burns in 180° of the trabecular meshwork, followed by treatment to the other 180° at a later date if necessary, reduces the severity of these pressure rises. Subsequent loss of pressure control can be very sudden after

visual performance, that is, visual acuity not correctable with conventional glasses or contact lenses. They may have cloudy vision, constricted fields, or large scotomas. There may be additional functional complaints: glare sensitivity, abnormal color perception, or diminished contrast. Some patients have diplopia. A frequent complaint is confusion from overlapping but dissimilar images from each eye. The term “low vision” covers a wide range. A person in the early stages of an eye disease may

or more sessions, and possibly a loaner lens for home or job trial. Older patients usually need more adaptation time and reinforcement than younger or congenitally impaired persons. Practitioners and staff benefit from training programs to learn how to manage a low-vision patient in the office. Basic setups for incorporating low vision into a practice are reviewed in a number of publications. Instruction is the key to success in vision rehabilitation. Over 90% of patients succeed with

All patients with squamous cell carcinoma of the eyelid should be advised of the risk of residual or recurrent tumor post-treatment and encouraged to adhere to recommended follow up. Figure 4–14.
