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.
