Introduction: The purpose of this study was to examine the relationship between diabetes and glaucoma.
Methods: Consecutive 143 subjects with primary angle-closure glaucoma and 127 subjects with primary open-angle glaucoma (control) were studied retrospectively at an urban Veterans Administration Hospital. In addition to ocular examination findings, body mass index (BMI) and diabetes mellitus (DM) status were recorded.
Results: All subjects in this study were male. The mean age was 72.3 years old in primary open angle versus 71.1 in primary angle-closure subjects. Half of the subjects with angle closure and 70% of open-angle subjects were self-identified as African–American. BMI was not significantly different between the two groups (28.2 in open angle vs. 28.7 in angle closure; P = 0.45). The percentage of DM was higher in subjects with primary angle closure than in those with primary open-angle glaucoma (43% vs. 29%, P = 0.001; Chi-square test). The odds of having DM were nearly two times higher in angle-closure subjects than open-angle subjects (Logistic regression, P = 0.01, 95% confidence interval: 1.17–3.30).
Conclusion: In this retrospective study, diabetes was found to be associated with higher risk for primary angle-closure glaucoma.

Ocular perforating is the most dreaded scenario to confront in patients with scleromalacia perforans. Despite its low prevalence, the progression of scleral necrosis to exposed uvea represents one of the ophthalmic emergencies with a high risk of loss of ocular content whose surgical treatment is performed autologous or heterologous tissue patches. This study describes six patients referred to the ophthalmology service of the Edgardo Rebagliati Martins National Hospital in Lima with a clinic history of autoimmune diseases and scleromalacia perforans >10 mm size, treated with autologous fascia lata grafting in addition to topical and systemic immunosuppressive treatment.

Purpose: The aim of this study is to compare the reduction percent of intraocular pressure (IOP) after selective laser trabeculoplasty (SLT) or pattern laser scanning trabeculoplasty (PSLT) in a group of patients with hypertensive glaucoma.
Materials and Methods: A quasi-experimental prospective study of the patients with baseline IOP of 20 mmHg or more (with at least 1 IOP lowering medication) underwent either PSLT or SLT at 360°. IOP was measured in the following time points: Hour 1, Day 1 and 7, months 1, 3, 6, and 12 after the laser procedure.
Results: The mean age was 68.1 ± 10.1 in the PSLT group and 71.8 ± 4.0 in the SLT group. Eleven eyes (8 patients) underwent PSLT and 9 eyes (6 patients) underwent SLT. Baseline IOP was 22.45 ± 2.4 mmHg, PSLT; 25.0 ± 2.2 mmHg, SLT; (P > 0.05) on an average of 2.4 medications. In the PSLT group, the mean IOP at 1 h, 1, 3, 6 and 12 months was 19.0 ± 5.0, 14.7 ± 2.4, 15.3 ± 3.0, 14.5 ± 2.7, and 13.0 ± 3.1, respectively. In the SLT group, the mean IOP at 1 h, 1, 3, 6 and 12 months was 25.6 ± 6.4, 15.9 ± 4.4, 15.3 ± 2.6, 16.7 ± 4.8, and 21.2 ± 4.3, respectively. IOP was significantly lower in the PSLT group compared to the SLT group at 1 h (P < 0.01) and 12 months (P < 0.01). No serious adverse events were recorded.
Conclusions: PSLT was similar in effect compared to SLT at 1, 3, 6 months, and more effective than SLT at 12 months.

Effective therapeutic options are limited to the management of exudative retinal detachments (RDs). The authors describe the resolution of the case following partial-thickness scleral resection. This 31-year-old male presented with a bilateral exudative RD. There was no history of steroid use either locally or systemically. The fundus eye showed typical of chronic exudative RDs. The axial length was 16.08 mm in the right eye and 15.17 mm in the left eye. Thickening of the sclera was evident in ocular ultrasound. Considering an axial length (nanophthalmic eye), four partial-thickness scleral resections were performed. The exudative RD resolved at 4 months. Partial-thickness scleral resections may be considered as an option for treating chronic exudative RDs patients with nanophthalmic eye.
