Correlation between metabolic controls and changes in retina in patients having diabetes.

INTRODUCTION: Diabetes mellitus is as old as the human race. Retinopathy, being one of complications of diabetes mellitus, is the most common cause of blindness. This study was aimed at analyzing the correlation between retinopathy and duration of disease, metabolic control, and obesity. MATERIAL AND METHODS: The study sample consisted of 135 patients divided into the experimental group of 90 patients with retinopathy and the control group of 45 patients without retinopathy. The patients were exa- mined according to standard protocols: anamneses, endocrinology, ophthalmology exams, biochemical analyses, and anthropometric measurements. RESULTS: The average age of patients was 60.13 +/- 9.29 in the experimental group, while it was 57.55 +/- 4.85 in the control group. The average duration of disease was 11.71 +/- 5.8 and 14.40 +/- 7.68 in the control group experimental group, respectively. The following statistically essential differences between the control and experimental group were found: in duration of disease (11.71 +/- 5.85; 14.40 +/- 7.68; r = 0.000), in glycemia (7.02 +/- 2.20; 8.34 +/- 3.18; p = 0.000), in glycosylated hemoglobin A1C (HbA1C) (7.16 +/- 1.37; 8.22 +/- 2.05; r = 0.000), in triglycerides (1.92 +/- 0.72; 2.63 +/- 1.60; r = 0.001), and in body mass index (23.94 +/- 2.65; 27.66 +/- 15.13; r = 0.000). CONCLUSION: There is a positive correlation between duration of disease, glycosylated hemoglobin A1C, triglycerides, body mass index - obesity and retinopathy. A significant statistical correlation among those parameters has been found in patients with diabetic retinopathy.

Cataract surgery in patients with ocular pseudoexpholiation.

MATERIAL AND METHODS: Retrospective 5-year study based on general and ophthalmic history records, and including 268 eyes (174 patients), aged 50 years and over. Ophthalmological examination involved visual acuity, measuring of intraocular pressure, slit lamp examination and indirect ophthalmoscopy. Type of surgical treatment was tailored for each patient (extra capsular cataract extraction, phaco-emulsiphication). RESULTS: Preoperative slit lamp examination showed phacodonesis in 17.91% (47), iridodonesis in 2.98% (8), pigment dispersion in 6.72% (18), lens subluxation in 4.85% (13) on the total. Extra capsular cataract extraction was performed in 36.94% (99) and phaco-emulsiphication in the others. Analysis of intra operative complications showed: posterior capsular rupture 17.91% (48), zonular dialysis or break 5.97% (16), lens subluxation 1.86% (5), intraocular bleeding 2.98% (8), vitreous loss 13.80% (37). Postoperative complications include: anterior chamber reaction 45.90% (123), intraocular lens tilt 15.67% (42), endothelial decompensation 21.64% (58), subluxation/luxation IOL 3.73% (10), secondary cataract 21.46% (58), pigment dispersion 37.68% (101), increased IOP 13.80% (37), residual lens matter 13.80% (37), hyphema 3.73% (10), posterior synechiae 6.72% (18), iris prolapsus 2.73% (8). CONCLUSION: Cataract surgery in PES will frequently encounter small pupils, shallow anterior chambers, posterior adhesions, weak zonular support, partial subluxation or complete dislocation of lens. Authors presented the best possible approach on PES and surgical methods for patients with cataract with special accent of possible surgical complications.
