RESUMO
PURPOSE: To prospectively evaluate the intraocular pressure (IOP) lowering ability, retreatment rate, and complications of transcleral Diode laser cyclophotocoagulation using a higher power setting than what is generally recommended. PATIENTS AND METHODS: A total of 36 eyes of thirty six patients with refractory glaucoma, and who fitted our inclusion criteria underwent Diode cyclophotocoagulation. The laser power was set at 2250 mW, with a duration of 2000 ms, and a total number of 28 shots for the first treatment and 20 shots for any consequent one. The patients were followed up for 1 year with the following outcomes being analysed: IOP, visual acuity, change in the number of medications, and complications. RESULTS: The mean IOP decrease was 53% (P < 0.05), and 72.2% of the patients maintained an IOP < or =21 mmHg for the whole duration of the study The number of medications necessary to control the pressure, significantly dropped from 2.8 to 0.89 (P < 0.05), and 25% of the patients needed the treatment to be repeated only once. In all, 33% of the patients improved their visual acuity after the treatment, while 22% worsened, and the rest stayed the same. The most common treatment complications were conjunctival injection and corneal oedema, and these were both transient and reversible. CONCLUSION: The use of the higher power setting of 2250 mW, resulted in a sustained lower IOP, less use of medications, less need for retreatment, relative preservation of visual acuity, and only reversible complications.

Benign ductal cysts of the accessory lacrimal glands are uncommon lesions of the orbit, arising from the glands of Wolfring and Krause. We report two patients with histopathologically proved cysts in whom CT scans revealed well-circumscribed extraconal cystic lesions adjacent to the globe, involving both eyelids. Radiologists should be aware of these rare lesions so as to include them in the differential diagnosis of orbital cysts.

PURPOSE: To report the rare occurrence of tick infestation of the eyelid margin. METHODS: A 58-year-old woman was initially examined with a small yellow lesion of the left upper eyelid margin that appeared after she felt a sting near her eye. Close examination disclosed an insect body attached to the eyelid margin. En bloc excision of the insect with part of the eyelid was performed. RESULT: Gross examination of the specimen identified the organism as the nymph stage of a bloated tick of the genus Hyalomma but of an uncertain species. CONCLUSION: Ticks (Hyalomma) can become embedded in the meibomian gland orifice and manifest as a mass at the eyelid margin.
