Primary trabeculotomy compared to combined trabeculectomy-trabeculotomy in congenital glaucoma: 3-year study., Khalil, Dalia H., and Abdelhakim Mohamad A. S. E. , Acta ophthalmologica, 2016 Nov, Volume 94, Issue 7, p.e550-e554, (2016) Abstract

PURPOSE: To compare the outcome of primary trabeculotomy with that of combined trabeculectomy-trabeculotomy (CTT) with mitomycin C (MMC) in children with congenital glaucoma.

METHODS: This is a prospective comparative study, carried out on a cohort of 28 eyes (28 infants) with congenital glaucoma. Infants with proved congenital glaucoma [based on intra-ocular pressure (IOP), cup/disc (C/D ratio), corneal diameter and axial length measurements] were randomly allocated to either group A (trabeculotomy) or group B (CTT with MMC). Postoperatively, all patients were followed regularly for 3 years; for IOP and C/D evaluation. Criteria for successful outcome included resolution of corneal oedema, reversal of disc cupping, and IOP 18 mmHg or less.

RESULTS: Success rate in each group was 85.7% (p = 1.00). All preoperative parameters, including horizontal corneal diameter, axial length, IOP and C/D ratio, were not statistically significantly different between the two groups. Also, postoperative C/D ratio, IOP, IOP difference and percentage difference (compared to preoperative values), at different follow-up visits, were not statistically significantly different between both surgical techniques. Comparing preoperative to postoperative IOP and C/D ratio in each group was statistically significant.

CONCLUSION: Both primary trabeculotomy and CTT with MMC had similar outcomes, which could mean that trabeculotomy could be resorted to first.

Optical coherence tomography findings in patients with bipolar disorder., Khalil, Mohamed A., Saleh Alia A., Gohar Sherif M., Khalil Dalia Hamed, and Said Mohamed , Journal of affective disorders, 2017 08 15, Volume 218, p.115-122, (2017) Abstract

BACKGROUND: Research in bipolar disorder suggests the presence of structural brain abnormalities. It is not clear whether these findings are trait markers or operate with the onset and progress with disease severity and duration. Optical coherence tomography (OCT) is a non-invasive technique that detects degenerative changes in the retina reflecting brain degeneration. This study aimed at detecting these changes and relating them to disease severity and clinical characteristics.

METHODS: A case-control study conducted in Psychiatry and Addiction Medicine hospital, Faculty of Medicine at Cairo University. Forty inpatients with bipolar disorder -according to the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) - were compared to forty matched healthy controls. Patients were subjected to the Structured Clinical Interview of DSM-IV (SCID-I), Hamilton Depression Rating Scale (HAM-D) and Young Mania Rating Scale (YMRS). Both patients and controls were subjected to OCT.

RESULTS: Patients showed thinning of Retinal Nerve Fiber Layer (RNFL) relative to control subjects in most of the OCT parameters including Right average (p<.001 and 95% CI [14.39, 19.84]), Lt average (p<.001 and 95% CI [13.03, 19.42]). Patients also showed decreased Ganglionic Cell Complex (GCC) significantly in Rt average (p=.002 and 95% CI [2.33, 9.78]), Lt average (p<.001) and 95% CI [4.47, 11.63]. Age at onset, number of episodes, and severity did not significantly correlate with OCT parameters.

LIMITATIONS: The small sample and absence of follow-up.

CONCLUSIONS: Patients with bipolar disorder show degenerative changes detected by OCT in relation to healthy controls.
