Correlation of visual field defects and optical coherence tomography finding in migraine patients

The aim of our work was to detect any structural or functional visual defects during and in between the attacks in patients with migraine. Sixty patients with migraine as well as sixty age and sex matched controls were included. All cases were subjected to full ophthalmological examination. Cases with any previously known optic nerve abnormalities or with history of increased intraocular pressure were excluded from this study. A full threshold 24-2 automated perimetry as well as optical coherence tomography [OCT] were performed for retinal nerve fiber layer [RNFL] thickness. Correlations between results of study group with migraine and controls were analyzed and recorded. There was a statistically significant difference between the patients with migraine and the controls in visual field analysis which was [P < 0.05] for generalized visual field deficits and [P < 0.001] for localized visual field deficits during the attack with no statistically significant difference in visual field in between the attacks [P > 0.05]. OCT RNFL thickness had no statistically significant difference between migraine and control groups [P > 0.05]. Migraine can cause functional ocular disorder without any structural abnormalities

recurrence of pterygium after different modalities of surgical treatment

To assess and compare the recurrence rate of pterygium after limbal stem cell transplantation versus amniotic membrane transplantation [AMT] as ocular surface reconstructing measures in recurrent pterygium, also evaluation of the use of antimetabolite drugs as adjunctive therapy for AMT. Prospective randomized comparative study included 60 eyes of 48 patients with recurrent pterygia. Informed consents were taken from all patients. Primary pterygium excision was performed 6-15 months ago; the cases were divided randomly into three equal groups: Group 1: included 20 eyes with excision of the pterygium and application of limbal stem cell transplantation with conjunctival autograft, group 2: included 20 eyes with excision of the pterygium followed by AMT and group 3: included 20 eyes in which surgical excision of pterygium was followed by intra-operative application of low-dose of MMC [0.05%] for 3 min then using AMT. The study included 36 males and 12 females of age ranged from 28 to 52 years. The recurrence rate was 2 eyes in group 1 [10%] [limbal stem cell transplantation + conjunctival autograft], 6 eyes in group 2 [30%] [AMT] and 4 eyes [20%] in group 3 [MMC + AMT]. The rate of recurrence was significantly different between the three groups [P < 0.001]. Limbal stem cell transplantation together with conjunctival autografting proved to be more effective in prevention of pterygium recurrence and in rapid restoration of normal epithelial morphology. MMC in addition to AMT decreases the incidence of recurrence
