RÉSUMÉ
Congenital corneal anaesthesia [CCA] is a rare clinical entity which can occur as an isolated anomaly or can be associated with some systemic disorders, usually the latter. CCA was diagnosed in a 2 1/2 year old girl from the history of self-inflicted ocular injuries and non-healing corneal ulceration, and evaluation of the corneal sensations

We describe an HIV-seropositive patient who presented with bilateral superficial epithelial keratitis due to protozoal infection by the microsporidia Encephalitozoon cuniculi. Diagnosis was made by clinical and cytological examination of conjunctival and corneal scrapings and was further confirmed by light and electron microscopy

Anterior capsulotomy is a key step in cataract surgery. Here we report our experience with two techniques, namely can-opener capsulotomy [COC] and continuous curvilinear capsulorhexis [CCC]. Which technique is chosen is partly influenced by the type of cataract present: it was mature in 52.1%, immature in 42.2%, and associated with pseudoexfoliation in 5.8% of cases. Posterior capsular tears occurred in 7% of all operations [7.8% of all 90 cases of COC, and 5.8% of all 52 cases of CCC]. Five of the total of 10 posterior capsular breaks occurred in eyes with mature cataract [a rate of 6.8%], 2 in eyes with immature cataract [a rate of 3.3%], and 3 in eyes with pseudoexfoliation [a rate of 37.5%]; this stresses the significance of local population factors among the causes for the relatively high rate of capsular rupture experienced by us. Of all posterior capsular breaks, 70% happened during the phase of irrigation and aspiration of cortical material. This step was most dangerous in the group operated using the COC technique. Six out of seven cases [85.7%] of posterior capsular rupture in this group happened during irrigation and aspiration of cortex. While in the group operated using the CCC technique, the risk of posterior capsular rupture was equally divided between nucleus delivery, irrigation/aspiration and intra -ocular lens implantation [one case for each step]

We report the findings in an of eye a patient who, in 1980, underwent excision of a pterygium three times in the one year. The second and third operation were followed by beta irradiation. The 3600 cGy applied in two overlapping fields during the second of these irradiations had resulted in 7200 cGy being applied near the nasal limbus, which is where the most severe changes were seen. These consisted of corneal thinning [thickness estimated to be < 40% of normal] near the limbus at 3 o'clock, and scleral necrosis adjacently, permitting uveal tissue to shine through. A large, elevated and calcified plaque covered the nasal part of the rest of the sclera, right up to the caruncle. Vision in this eye was reduced to hand movements, mainly due to corneal scarring and immature senile cataract

We report a case of Kleeblattsch = del [cloverleaf skull] syndrome in a newborn. This fatal disorder is very rare, only a few cases have been recorded in the literature. Among multiple systemic deformities, ocular structures are also severely affected, with involvement of the globe, orbit, and adnexa

A clinical study of 112 cases of vernal keratoconjunctivitis in the Eastern coastal region of the United Arab Emirates was carried out during a twelve-month period, starting from September of 1990. The disease manifested predominantly in the limbal form, with a majority of the patients suffering from active disease throughout the year, and only a small percentage of cases giving typical atopic and family histories. The predominance of the limbal form of vernal keratoconjunctivitis, especially in persons of dark complextion, provides evidence that genetic factors may play a role in the development of this disease, though environmental factors do influence the severity of it. A combination therapy of sodium cromoglycate and aspirin was effective in relieving symptoms and minimizing recurrences
