Case ReportsGiant cell arteritis with spontaneous remission.
Clinical manifestations of giant cell arteritis (GCA) are variable. Whether signs and symptoms present in an explosive fashion or insidiously, once manifest the course is usually progressive unless treatment is initiated. ⋯ Clinicians should be aware of this aspect of the disease in order to avoid a delay in diagnosis and treatment.

Supraorbital nerve block in trabeculectomy surgery: an observational case series.
Thirteen patients completed a visual analogue pain scale after trabeculectomy with topical anaesthesia and a supraorbital nerve block with 2 mL of lignocaine 2%. Ease of surgery was graded on a scale of 0-5. Inadvertent eye movements and episodes of orbicularis spasm were recorded. ⋯ Three subjects had inadvertent eye movements with ease of surgery recorded as 1 of 5 in 12 cases and 2 of 5 in one case. The novel application of this anaesthetic technique offers adequate analgesia in trabeculectomy surgery. However, a larger scale comparative trial is needed to further evaluate the value of this technique.

Historical ArticleOphthalmology in proverbs and aphorisms.
After a comprehensive review of available texts and literature covering five millennia, the authors present a collection of ophthalmic proverbs and aphorisms with an examination of their applicability within current medical knowledge. A total of 74 ophthalmic proverbs and aphorisms were retrieved from 130 texts and divided into seven categories: (i) importance of vision ('The eyes, like sentinels, hold the highest place in the body'); (ii) definition of blindness and anatomical observations ('The eye is protected by the lashes, eyebrows, and orbit'); (iii) diseases of the eye such as presbyopia, sensitivity to light and dry eye ('Tear in the eye is jewel'); (iv) the eye as a window of the body; (v) vulnerability of the eye ('The eye cannot oppose an awl'); (vi) health behaviours and protection of sight ('Be gentle with two: women and eyes'), and finally; and (vii) nutrition and vision ('Carrots improve vision'). The majority of these proverbs and aphorisms can be used as a guide, not for prognosis, diagnosis or cure, but rather for ocular health promotion.

Letter Case ReportsRecovery of postoperative visual loss following treatment of severe anaemia.
A 29-year-old pregnant woman noted acute visual loss following emergent Caesarean section complicated by excessive uterine bleeding. Postoperative visual acuity was count fingers in both eyes. ⋯ Following transfusion, the patient's vision improved over the next 6 months. In an otherwise healthy patient, visual loss associated with postoperative blood loss may still be partially reversible with correction of the anaemia, even after a delayed period of time.
